Decision Support for Public Alligator Harvesting in Georgia, Florida, and South Carolina	June 2017	Regulations for public alligator harvesting in the states of Georgia, Florida, and South Carolina are based on an assessment of current-year alligator population size against statistically-estimated historical trends in abundance. However, mechanistic models offer certain advantages over statistical models in that (1) they may be able to better predict harvest outcomes that are outside of historical experience, (2) they facilitate the making of optimal harvest decisions based on threshold conditions tied to the biology of the species, not the population's past performance, and (3) they provide a straightforward way to account for biological uncertainty about the response of populations to harvest management. In this project, we will employ a structured decision making approach to consider the problem of public alligator harvesting in the three participating state agencies. The approach will explicitly recognize the policy differences (management objectives and regulatory options) among the agencies, but it will take advantage of regional commonalities in population biology, habitat relationships, and sampling characteristics in the development of a set of decision models. Under this design, we expect that efficiencies can be created because the model set can be informed and improved by data contributed by any agency, and the models may indicate uncertainties toward which agencies can coordinate focused research efforts.
Pre-assessment Plan to Determine Potential Exposure and Injuries of Nesting and Hatching Loggerhead Sea Turtles	July 2011	The purpose is to determine and quantify exposure and injuries to the nesting adult loggerhead sea turtles that reside in and nest along the shores of the Gulf of Mexico resulting from exposure to MS Canyon 252 oil (hereafter referred to as oil). This study is being conducted in partnership with a separate yet identical project to quantify exposure and injury to adult Kemp’s ridley turtles that nest primarily along the Texas coast. Combined, these two studies will assess nesting turtle impacts along the entire Gulf coast of the United States.	None
Incubation temperatures of loggerhead turtle (caretta caretta) nests On NW Florida Beaches	March 2012	The ratio of males to females in a population is an important feature of population structure. Sex ratio directly relates to reproductive rate and adaptive capability of a population (Ridley 1993) and is necessary for determining size, status, and dynamics of the population. For all species of sea turtles, basic knowledge of natural existing sex ratios has been missing until recently and is still not complete for most nesting groups. Sex determination of sea turtles is dependent upon the temperature at which the eggs are incubated (Yntema and Mrosovsky 1982).	Sex determination of sea turtles is dependent upon the temperature at which the eggs are incubated (Yntema and Mrosovsky 1982). Several features of nesting beaches have been shown to impact incubation temperatures therefore understanding temperatures of the beach in which eggs incubate is critical to our knowledge of sex ratios.
Gopher Tortoise (gopherus polyphermus)Population Survey For St. Marks NWR-Line Transect Distance Sampling	August 2011	The gopher tortoise (Gopherus polyphemus), unlisted range, is among the U.S. Fish and Wildlife Ecological Services 2008 priorities as a “preclude the need to list” species. This project furthers the Strategic Habitat Conservation process by providing critical information necessary for outcome-based monitoring, planning and management at St. Marks National Wildlife Refuge.
Collection of Digital Serial Imagery in Support of Aquatic Invasive Species Program And CERP	May 2011	In its 10th year, 2010 was a landmark year for the UF/USACE UAS Program. The team now has developed a very reliable, waterproof platform (Nova 2.1) which is totally autonomous including takeoff (hand tossed) and landing. The FAA requirement to fly within 1 nautical mile line of sight required land and water landings in the extensive Everglades and Lake Okeechobee. The Nova 2.1 performed 40+ individual flights without incident in 2010.	None
Southeastern Adaptive Management Group (SEAMG)	September 2013	The Southeastern Adaptive Management Group (SEAMG) was created in 2001 for the purpose of achieving a better science-based approach to wildlife conservation and management. The principal mission of the group is “To better integrate research and management for the purpose of improving how natural resource management decisions are made.” As part of this mission, the SEAMG is responsible for exploring and developing quantitative tools that improve and facilitate the integration of research and management. A distinguishing feature of the SEAMG is that it seeks ways to achieve a heightened level of integration between researchers and managers. At this level of integration, management actions themselves are viewed as opportunities for learning through experimentation, and the selection of management actions generally includes compromises between the (possibly) long-term value of learning and the short-term value of achieving more immediate management objectives. SEAMG scientists interact closely with scientists and managers of cooperating organizations to solve problems of natural resource management.	None
Startegic Habitat Conservation for Florida Scrub-Jays at Merritt Island National Wildlife Refuge	July 2011	This project involves the development of a management strategy for oak (Quercus spp.) scrub that will maximize the long-term demographic performance of Florida scrub-jays (Aphelocoma coerulescens). The project focuses on the Happy Creek Scrub Reserve Unit of Merritt Island National Wildlife Refuge, which is an area with an ecological legacy of fire suppression. The objective of this project is to determine how creation of bare ground by plowing could supplement prescribed burning to help maintain better habitat conditions for Florida scrub-jays.	None
Linking Snail Kite Foraging Activity, Habitat Quality, and Critical Demographic Parameters to Guide Effective Conservation	April 2012	Recent demographic studies reveal alarming trends in the snail kite population in Florida. Kite numbers have drastically declined since 1999, with the population essentially halving from 2000 to 2002 and again from 2006 to 2008.	Information gaps (identified in Figure 1) currently preclude our ability to simultaneously manage hydrology with respect to vegetation, snails and kites in WCA3A. Synthesizing and analyzing available overlapping datasets, as well as collecting additional targeted data, will help elucidate key components in this system’s dynamics, which will aid management decisions for WCA3A and improve recovery planning efforts for the endangered snail kite.
Nesting Habitat and Nest Failures of the Everglad Snail Kite on Kissimmee Lakes and Nesting, Recruiting and Foraging Ecology of the Florida Snail Kite in Lake Tohopekaliga	March 2013	The Snail Kite is a federally endangered raptor whose population in Florida has recently undergone precipitous declines. The remaining population remains heavily dependent upon the Kissimmee Chain of Lakes (KCOL), a group of lakes in central-Florida that is subject to many anthropogenic influences, including water and vegetation management. It is therefore crucial to gain an understanding of how the habitat on these lakes influences kite reproduction as well as determining reasons for nesting failure and success.	The proposed study will provide critical information regrading reasons for snail kite nesting failure, by looking at the vegetative communities that supply nesting substrate, presence of predators, and the role that interspecific avian assemblages play on the success rate of the nests.
Demographic, Movement, and Habitat of the Endangered Snail Kite in Response to Operational Plans in Water Conservation Area 3A	April 2011	The objective of this research is to monitor the birds' response to environmental changes (anthropogenic and natural) focusing on the most critical demographic parameters: survival, reproduction, recruitment, and population growth rate.	None
Surveys of Snail Kite Breeding and Habitat Use in the Upper St. Johns River Basin	February 2011	The purpose of this project is to document snail kite usage and reproduction within the Blue Cypress Marsh Complex (BCMC) during 2008,2009, and 2010. Since the snail kite population in Florida is best viewed as a single population, we also report additional demographic data at the scale of the whole population.	None
Production and evaluation of an autonomous UAV system for natural resources management	December 2009	The multidisciplinary team of collaborators at University of Florida has developed a small autonomously-controlled UAV system for the detection, classification, tracking, and counting of animals, plants, or other objects or terrain characteristics. The purpose of this project is to pursue enhancements to an existing unmanned aerial vehicle (UAV) system to improve its present applicability and future potential for a variety of natural-resource uses. The research is interdisciplinary in nature and includes engineering, ecological, photogrammetric, and remote sensing elements and experts in those disciplines. Research objectives and major tasks of this three-year project include, but are not limited to, the following: 1. Improvements in construction and electronics to enhance the reliability and ease of operation of the aircraft. 2. Progress in the development of geographical referencing capability for imagery collected from the aircraft. 3. Training of personnel for testing of a complete UAV system for research and management applications. 4. Development and testing of thermal infrared (TIR) sensor capability. 5. Evaluation of operating and maintaining a UAV system. 6. Exploration of future UAV system enhancements for remote-sensing applications. [continuation of RWO 228]	None
Biodiversity Using Prediction	May 2013	The objectives of this project are to develop the knowledge necessary to make accurate predictions of the response of species and their ecosystems to climate change. These predictions are necessary to inform natural resource managers on how to appropriately adapt conservation strategies for a changing future, and both Federal and Florida state agencies have identified the understanding of global climate change impacts as priority issues. This project is a subset of a larger project with the USGS Southeast Ecological Science Center and Florida State Universitiy that will used downscaled climate predictions from coupled Atmospheric-Ocean General Circulation Models (AOGCMs) to peninsular Florida, and then use existing hydrologic models for each basin to predict how the changes in climate will influence water flow and stage in the systems. Our part of the project will then link floral and faunal responses of particular indicator species (an endangered vole and small mammal, raptor, and fish communities) to those predicted changes in water availability using empirical analyses of both newly collected and existing data and population models for each taxon.

Alligator distribution, size, and hole occupancy and crocodile juvenile growth and survival	March 2015	Responses of crocodilians are directly related to suitability of environmental conditions including hydropattern. Correlations between biological responses and environmental conditions contribute to understanding of species' status and trends over time. Positive or negative trends of this indicator relative to hydrologic changes permit assessment of positive or negative trends in restoration impacts. Restoration success or failure would be evaluated by comparing recent and future trends and status of crocodilian populations with historical population data and model predictions; as stated in the CERP hypotheses related to alligators and crocodiles (CERP MAP section 3.1.2.5 and 3.1.2.6, 2004). Importantly, these data can be used in an analysis designed to distinguish between effects of CERP and non-CERP events such as hurricanes or droughts. Data from this MAP project will be used to develop, refine, and validate spatially explicit crocodilian population models, which can then be applied in setting interim goals and targets. This project also fills a critical research need (refining crocodile/salinity relationship) identified as part of RECOVER recommendations for setting interim goals and targets. The objectives and work proposed here follow the recommendations from the MAP, Part 2: 2006 Assessment Strategy for the MAP and the RECOVER GE Trophic Sub-team, to enhance and build upon research and monitoring programs for alligators and crocodiles that have been funded as part of the CESI, Modified Water Deliveries, and RECOVER MAP. This work is designed to satisfy requirements for monitoring changes in alligator and crocodile populations over different time scales as a result of restoration. Generally, the statement of work (SOW) described below is intended to support four broad objectives of the MAP: 1. Establish pre-CERP reference state including variability for each of the performance measures; 2. Determine the status and trends in the performance measures; 3. Detect unexpected responses of the ecosystem to changes in stressors resulting from CERP activities; 4. Support scientific investigations designed to increase ecosystem understanding, cause-and-effect, and interpret unanticipated results. CERP and RECOVER MAP hypotheses and goals related to crocodilians Alligators � Expand distribution of reproducing alligators and alligator holes to southern marl prairies/rocky glades and restore the keystone role of alligator holes as refugia for aquatic fauna; � Provide salinity regimes that are suitable for expansion of reproducing alligators into oligohaline portions of estuaries; � Increase in current populations and body condition of reproducing alligators in ridge and slough landscape. Crocodiles � Restoration of freshwater flows to estuaries and salinity regimes will increase growth and survival of crocodiles. � Restoration of location of freshwater flow will result in an increase in relative density of crocodiles in areas of restored flow, such as Taylor Slough/C-111 drainage. Tasks Alligators 1. Finish developing and testing a monitoring program for relative distribution, size (condition), nesting and hole occupancy rates of the American alligator in response to CERP projects as specified in the MAP. The monitoring program and procedures developed will provide the baseline for future comparisons and an effective means for evaluating restoration success for the American alligator in the GE ecosystem. 2. Monitor changes in alligator populations due to restoration over short (body condition), medium (distribution, hole occupancy) and long (nesting) temporal and spatial scales. Crocodiles 1. Finish developing and testing a monitoring program for nesting, condition, growth and survival of crocodiles in areas that will be affected by CERP projects. 2. Monitor changes in nesting, condition, growth, and survival of crocodiles in response to CERP projects.	None
Adaptive Management of Gulf Coast Salt Marshes Considering Sea Level Rise and Recovery of the Endangered Florida Salt Marsh Vole	September 2010	The Florida Cooperative Fish and Wildlife Research Unit (FCFWRU) is proposing a multidisciplinary, coordinated research effort on the effects of the combination of decreased fresh water flow and sea level rise to coastal ecosystems and habitats in the Big Bend region of Florida. A key species of interest is the salt marsh vole (Microtus pennsylvanicus dukecampbelli) which is possibly the rarest of Florida's mammals. The Florida Cooperative Fish and Wildlife Research Unit (FCWRU) and Lower Suwannee National Wildlife Refuge (LSNWR) collaborated to trap for salt marsh voles and to establish several transects through salt marshes during winter 2008.

Structured decision making, ecological thresholds and the establishment of management trigger points	December 2009	Discussions of "ecological thresholds", "acceptable variation" and "management trigger points" occur frequently in discussions of ecological monitoring programs (e.g., Noon 2003). However, these discussions tend to be vague and rambling, with some agreement on the general need for thinking about such issues, but little detail about how to proceed to actually define these concepts either generally or for specific problems (e.g., specific monitored systems). This recognition appears to have motivated the Request for Proposals on this topic as part of the USGS National Park Monitoring Program. Researchers thus propose to do the following. (1) Provide a conceptual framework for thinking about the concepts of thresholds, acceptable variation and trigger points in terms of a structured decision process. In particular, researchers will demonstrate that structured decision making provides a natural framework for such concepts and leads to clear thinking about the nature of such concepts and means of defining them. (2) Provide a step by step procedure that leads to a decision matrix for optimal decisions. Decision matrices specify what management action to take for each possible set of values of the state variable(s) of interest and thus explicitly provide thresholds and trigger points that are optimal with respect to objectives. Researchers will work with National Park personnel from one or more parks to implement the approach with one or more example issues. Specifically, they will begin with the development of objectives and available management actions, move to model(s) development, consider the kind of monitoring program(s) available to estimate system state and then develop decision matrices that are optimal with respect to the objectives.

Effects of Spotted Bass on Shoal Bass and Largemouth Bass in the Flint River	December 2025	Shoal Bass are endemic to the Apalachicola–Chattahoochee–Flint (ACF) River basin in Florida, Georgia, and Alabama and support a socioeconomically important fishery in the ACF basin. Introduction of nonnative Spotted Bass into this system is cause for concern due to potential negative interactions with native Shoal Bass and Largemouth Bass. We will assess how Shoal Bass and Largemouth Bass have responded to the introduction of Spotted Bass in the Flint River, evaluate how quickly Spotted Bass have spread throughout the system, and identify the environmental conditions associated with preferred sites. This project will provide new insights for managing native bass species and associated fisheries in the ACF basin.

Assessing angler opinions and perceptions about non-native freshwater fishes in Florida	June 2024	More non-native freshwater fish species have been found in Florida than any other state. These introductions often present major challenges to resource management agencies, although some non-native fishes support socioeconomically valuable fisheries that benefit anglers and fisheries managers alike. For instance, in south Florida, popular fisheries have developed for species such as Peacock Bass, Clown Knifefish, Oscar, and Mayan Cichlid. However, in other parts of the state, non-native fishes such as Pterygoplichthys spp. cause bank erosion and destabilization and associated economic and aesthetic costs. Overall, human perceptions of non-native fishes in Florida are likely to be highly variable, yet this subject has scarcely been investigated, much less used to inform fisheries management in the state. The purpose of this project is to develop and disseminate survey instruments to gauge opinions of anglers and the general public about non-native freshwater fishes throughout the state of Florida.

FLAKES: A multi-organization dataset to investigate invasive plant management impacts in Florida lakes	December 2024	Aquatic plant management is critical for maintaining open waterways for navigation and recreation, reducing mosquito-borne diseases, and protecting freshwater ecosystems. Florida invests heavily in aquatic plant control, with state and federal agencies spending over $20 million annually on management. Most aquatic plant management efforts in the state involve herbicide application, with a primary focus on hydrilla, water hyacinth, and water lettuce. Although these three species are classified as invasive and have been present in Florida for decades, research on their impacts has yielded inconsistent results. There is a critical need to better characterize effects of invasive plants and their management on aquatic ecosystems in Florida. To this end, our objectives are to evaluate (1) the direct impacts of invasive plant management on plant species abundances and (2) the indirect impacts of invasive plant management on Largemouth Bass populations through changes in plant abundances after curating a master dataset composed of long-term data collected by various agencies across Florida.

Assessing effects of Tilapia on Largemouth Bass and Bluegill reproduction, recruitment, and growth	June 2024	Quantitative research evaluating the effects of non-native freshwater fishes on native species in Florida is lacking despite the importance of this information for management. To address this knowledge gap, we will conduct a pond study evaluating the effects of one of the most widespread genera of non-native freshwater fish, Tilapia <i>Oreochromis</i> spp. (<i>Oreochromis</i> <i>aureus</i>, <i>Oreochromis</i> <i>niloticus</i>, and their hybrids), on two ecologically and socioeconomically important native fishes, Largemouth Bass <i>Micropterus salmoides</i> and Bluegill <i>Lepomis macrochirus</i>. Introduced in the 1960s, Tilapia spp. have become widely established throughout peninsular Florida. Previous research on the impacts of high densities of Blue Tilapia <i>Oreochromis aureus </i>demonstrated reduced age-0 production, recruitment, and growth of Largemouth Bass. However, these studies were limited in that they only evaluated the effects of high densities of Blue Tilapia on age-0 Largemouth Bass production and growth. We aim to build on these studies by evaluating the impacts of both low and high density Tilapia populations on age-0 and age-1 Largemouth Bass and Bluegill in 0.4-ha ponds (n = 9). The proposed study site is located near the current latitudinal limit of established Tilapia populations in Florida, which makes it an opportune location to study interactions of Tilapia with Largemouth Bass and Bluegill given possible Tilapia range expansion and/or population growth in north central Florida and the panhandle due to climate change.

Observing Flight Initiation Distances of Florida Chelonia mydas in the Crystal Bay Area	October 2022	Vessel strikes have become a more significant threat as an increasing number of sea turtles around the world, and especially in Florida, are stranded (injured or killed) due to an increase in the number of strikes by recreational or commercial vessels over the past several decades. For effective management strategies to be established, threats to sea turtles must be thoroughly understood. Observing how green turtles (Chelonia mydas) react to oncoming vessels at varying speeds will allow for critical information surrounding these interactions to be recorded. We will conduct observational boat surveys to measure turtle response and flight initiation distance from the vessel and compare behaviors of turtles of different size classes. This research looks to improve the available information on a relevant threat for sea turtles not only in Florida but globally and will be useful for management organizations to help reduce vessel-related mortality.

Effects of climate change on barrier island habitat and nesting sea turtles.	May 2012	As the global climate changes it is likely to have significant effects on coastal habitats and the species that rely on this habitat for survival. Warmer temperatures and rising seas can increase beach erosion, altering oceanographic patterns and influencing sand temperatures. These changes to the coastal environment may greatly affect species such as sea turtles. Sea turtles spend most of their life at sea but rely on the shoreline for one critical life-history phase: nesting. Changes to beach topography, sand temperatures and oceanographic patterns may impact nesting success, change incubation rates and influence nesting site fidelity. Determining the effects of climate change on nesting sea turtles will help provide better management information for this threatened species.	None
Abiotic and biotic factors affecting fish occurrence, abundance, and growth in sixty Florida lakes	June 2026	Studying the effects of abiotic and biotic factors on fish populations is a long-standing tradition in fisheries science. However, there is less information on how fish populations and communities respond to abiotic and biotic factors across broad spatial extents, diverse lake types, and associated gradients in lake surface area, trophic state, and aquatic macrophyte coverage, particularly in Florida. There is a need to evaluate how environmental factors varying across large regions affect fish populations, fish communities, and fisheries management. Addressing these knowledge gaps could reveal useful information for managing fish populations and communities in regions with wide-ranging environmental conditions, and predicting how fish populations and communities may respond to environmental changes. The objective of this study is to investigate fish population and community characteristics in relation to abiotic and biotic factors across wide-ranging conditions of lake surface area, trophic state, and macrophyte abundance in Florida. Our research will generate data summaries and statistical models to quantify and predict fish occurrence, abundance, growth, and related population/community characteristics in Florida lakes.

Using long-term monitoring data to evaluate Largemouth Bass and Black Crappie population dynamics amid environmental change	December 2023	Largemouth Bass and Black Crappie are popular sport fishes that are widely distributed across Florida and most of the United States. However, there is limited information about how long-term environmental alterations (e.g., changes in climate, aquatic vegetation coverage, lake trophic status) affect these species and the valuable fisheries they support. This knowledge gap, combined with the ecological and socioeconomic significance of centrarchid fisheries, makes it important to study the effects of environmental alterations on Largemouth Bass and Black Crappie population dynamics (e.g., growth, survival). Such information will fulfill a management need for these high-profile species in Florida. Our primary objective is to evaluate if and how climate change, hydrilla expansion, and cultural oligotrophication have affected Largemouth Bass and Black Crappie population dynamics in lakes across Florida over the last 15 years. We will develop a variety of statistical models to understand historical trends in Largemouth Bass and Black Crappie population dynamics using data from the FWC Freshwater Fisheries Long-term Monitoring Program. We will also conduct a detailed social-ecological investigation of a unique, intensively managed reservoir fishery noted for its Largemouth Bass abundance and size structure to understand interactions among fish populations, aquatic habitats, and fisheries stakeholders. Our research will yield insights for understanding long-term trends in Largemouth Bass and Black Crappie population dynamics and interrelationships among fish, habitats, and people across Florida, yielding management-relevant information for FWC and other partners in fisheries management.

We will also conduct a detailed social-ecological investigation of a unique, intensively managed reservoir fishery noted for its Largemouth Bass abundance and size structure to understand interactions among fish populations, aquatic habitats, and fisheries stakeholders. Our research will yield insights for understanding long-term trends in Largemouth Bass and Black Crappie population dynamics and interrelationships among fish, habitats, and people across Florida, yielding management-relevant information for FWC and other partners in fisheries management.
Informing invasive species management amid climate and land-use change to build social-ecological resilience	June 2026	Climate change is a major phenomenon altering the distribution of non-native fishes and their ecological and socioeconomic impacts. The influence of climate change on water temperature has substantial implications for non-native fish distributions because it influences individual fish survival, growth, reproduction, and dispersal as well as population and community structure. Understanding water temperature variability and the effects of climate change on aquatic thermal regimes is critical for managing non-native fishes now and in the future, especially in Florida where nearly 200 non-native fishes have been documented. Despite the prevalence of non-native fishes in Florida, water temperature dynamics are poorly understood in lotic ecosystems that are prone to non-native fish occurrence (e.g., south Florida canals, Kissimmee, Ocklawaha, and Choctawhatchee rivers). Thermal habitat research in Florida’s lotic systems has not been conducted at sufficient spatiotemporal and ontogenetic resolution to predict when and where non-native fishes are likely to occur in the context of climate change. We will address these knowledge gaps by supplementing Florida’s network of 200 water temperature loggers by deploying 75+ additional loggers in key rivers and canals that are not currently well-monitored. We will use water temperature data to model non-native fish survival, reproduction, recruitment, and dispersal under different climate change scenarios from 2022–2070. We will develop these thermal habitat suitability models into relevant products for non-native fish management, including predictive maps of species distribution and spread. Ultimately, our research will promote development of robust, spatially explicit programs for managing non-native fishes in Florida.

Investigating Grass Carp movement, emigration, habitat use, and natural mortality after stocking at Lake Apopka	December 2024	Managing invasive plants such as hydrilla is a pressing issue for fisheries and aquatic resource managers in Florida. While herbicide treatment is a common approach for controlling hydrilla, it is often controversial. Human dimensions research indicates stakeholder support for alternative control techniques (e.g., Grass Carp stocking) to reduce the number of chemical treatments necessary to control hydrilla in certain areas of Florida. We will use radio telemetry to assess stocking mortality, natural mortality, movement, emigration, and habitat use of Grass Carp in Lake Apopka. We will use this information to develop a Grass Carp population model and identify strategies for balancing biological and chemical approaches for hydrilla control. This project will be a cooperative endeavor among FWC Freshwater Fisheries Research, FWC Division of Freshwater Fisheries Management, FWC Invasive Plant Management, and the Florida Cooperative Fish and Wildlife Research Unit at the University of Florida.

Leveraging habitat suitability modeling to inform management of nonnative fishes in a changing climate	December 2024	Florida has more than 200 nonnative fishes that cause major ecological and societal consequences. In this project, we will predict survival, reproduction, recruitment, and dispersal of priority nonnative fishes in Florida over the next 50 years to develop science-driven approaches for managing these species. We will generate predictive distribution maps, decision support tools, and stakeholder engagement activities to help manage nonnative fishes and inform the public about fisheries conservation. This project will involve close collaboration with fisheries managers to ensure that research products are useful for preventing the introduction, slowing the spread, eradicating, and controlling nonnative fishes.

Lessons from a long-term fisheries monitoring program: The Florida experience	June 2026	Fisheries managers need consistent, reliable information on fish populations across space and time to make informed management decisions. However, developing and sustaining long-term monitoring programs is inherently challenging for fisheries management agencies amid limitations in time, money, and personnel. This dichotomy—the value of fisheries monitoring on the one hand, the difficulty of monitoring on the other—makes it critical for fisheries agencies to formally evaluate their monitoring programs to maximize data reliability and program efficiency. In 2006, the Florida Fish and Wildlife Conservation Commission (FWC) implemented a long-term monitoring (LTM) program to track trends in freshwater fish population distribution and community structure in numerous water bodies throughout Florida. Although the LTM program is designed to document changes in fish communities and thereby inform fisheries management amid anthropogenic stressors (e.g., land-use change, non-native species), the LTM program has yet to be comprehensively evaluated. The purpose of this project is to thoroughly evaluate the LTM program—including ecological insights, sampling design and statistical rigor, fisheries management implications, and program delivery—in collaboration with the FWC.

Environmental correlates of fibropapilloma in green turtles.	December 2025	Fibropapilloma is a debilitating disease of green turtles that gives rise to tumor-like growths that can inhibit the animal's basic visual, foraging, and locomotor functions. It has been linked to the presence of a herpesvirus, however the expression of tumors appears to be dependent on a variety of co-factors. Increasing populations of green turtles in southeast US waters gives cause for concern, as some of these co-factors appear to be correlated with anthropogenic disturbances.

Assessing effects of anthropogenic and climate-induced change on health of coastal ecosystems.	December 2022	Florida’s coastline is constantly reworked by long and short-term climatic cycles. Shifts in the frequency and intensity of those cycles due to global change, in conjunction with anthropogenic alterations, are affecting the resilience of coastal habitats and the species that rely on them. This research will integrate existing approaches with novel techniques to examine the coupling of oceanographic and onshore processes and their effects on sea turtle nest incubation and dune stabilization. Sea turtles nest in a variety of beach environments, and the success of an individual nest is influenced by its location on the beach and the resulting incubation micro-environment. The effects of tide-driven gas exchange on sea turtle nest incubation, beach microbial communities, and dune stabilization have received little attention. Our recent research indicates that incursion and retreat of the saltwater wedge causes substantial movement of gases through the beach during the tidal cycle, and that alterations like beach nourishment have the potential to suppress this natural pumping effect. We will evaluate how nest incubation dynamics and productivity respond to altered gaseous environments. Additionally, we will examine the role of beach nourishment in shifting offshore/onshore organic matter budgets, and the implications for greenhouse gas emissions. The results of this work will identify how and where habitat suitability issues might arise, and inform sound conservation planning measures and better nourishment practices, including mitigation and alternative actions.

Birdsbesafe: Is a novel cat collar more effective at stopping domestic cats from killing birds at higher latitudes?	February 2022	Up to 4 billion birds are killed annually in the US alone by domestic cats. We examine a novel conservation tool that has the potential to be effective at keeping domestic cats from killing songbirds: the Birdsbesafe® cat collar cover. We are testing whether the BCC is differentially effective at various latitudes. Because birds at higher latitude birds have a shorter breeding season and a concurrent higher spike in testosterone then birds at lower latitudes, we predict that the more "distracted" breeding birds in the northern latitudes will show a higher magnitude difference in predation by cats with and without the BCC.

Movements and overwinter survival of juvenile Red Knots in Southeast US: Information needs for recovery planning	December 2024	Much of the focus of Red Knot research and conservation over the past twenty years has largely focused on just a few sites along the Atlantic flyway, primarily in the mid-Atlantic region. We currently do not fully know the distribution of juvenile Red Knots (approx. first 22 months after hatch). Without knowing where juvenile Red Knots occur, we could be missing key threats to this group such as habitat loss or degradation or human disturbance that need to be addressed. The primary goal of this project is to develop the information needed to make good conservation and management decisions on the juvenile life stage of Red Knots that will significantly contribute to the de-listing of the species. Specifically, we aim to identify the main area(s) where juvenile Red Knots occur during their first two years of life, how long they survive, if they recruit into the adult population, to achieve a better understanding of the potential threats where they occur, and to develop management recommendations to improve the conditions they face.

Colonial nesting wading bird tracking and habitat use assessment	December 2024	This study may inform and enhance future restoration planning for key colonial nesting wading bird species along the Alabama coast that were injured by the DWH oil spill. Overall research objectives include determining daily and seasonal movements, home range size, and habitat use by several species of colonial-nesting wading birds (tricolored herons, little blue herons, and possibly white ibis) in Mobile Bay, Mississippi Sound, and Perdido Bay, Alabama. The goals of this proposed project are to better understand the extent to which declines in colonial nesting wading bird populations result from habitat limitation versus other potential population-limiting factors, and in turn, which restoration approaches and techniques are most appropriate to effectively target and restore wading bird populations.

Effects of Coastal Dynamics & Climate on Loggerhead Turtle N...	May 2018	While some sea turtle populations appear to be in recovery due to protections enacted decades ago, loss of suitable nesting habitat, driven by climatic factors and anthropogenic responses to those factors, poses an increasing threat to the sustainability of established and newly founded nesting populations. Data on the responses of nesting sea turtles to perturbations and change in the onshore and nearshore coastal habitat is lacking, and this research seeks to fill those data gaps with relevant, actionable information. The study is a collaborative effort that include the University of Florida (Wildlife Ecology and Conservation, the Doris Duke Conservation Scholars Program,The Whitney Laboratory for Marine Biosciences, School of Natural Resources and the Environment, and the Archie Carr Center for Sea Turtle Research), the U.S. Geological Survey, the Florida Fish and Wildlife Conservation Commission, and the National Oceanic and Atmospheric Administration National Estuarine Research Reserve. Biological and physical beach data collected in monitoring efforts to date have contributed to the establishment of the first conservation easement for sea turtles in the United States.

Evaluation of the impact of artificial lighting on sea turtle hatchling orientation.	December 2020	Light pollution that associates with human development disorients sea turtle hatchlings. Although the light management to reduce artificial lighting is underway, the quantified spatial data on hatchling orientation accuracies and measurements to show the progress of the management efforts are limited. The present project provides information on the threats of artificial lighting that can be directly reduced in the North Atlantic Ocean and the Gulf of Mexico. The partners of the study include the Florida Fish and Wildlife Conservation Commission and multiple counties in the state of Florida. The project produces the models that predict hatchling orientation accuracies using light intensity data that can be easily collected by the stakeholders.

Nutritional ecology and husbandry of Dermatemys mawii	August 2020	Dermatemys mawii is a critically endangered fresh-water turtle endemic to Central America. Captive breeding programs for wild release have been identified as an important component of conservation efforts for D. mawii, but relatively little is known about their biology and ecology. Research is needed that will inform captive and wild management. Only a few scientific studies have been conducted that focus on the unique biology and ecology of D. mawii. This project is collaborating with the Belize Foundation for Research and Environmental Education and the Turtle Survival Alliance. Knowledge gained from this study will address the long-term conservation goals by informing husbandry practices, captive breeding protocols, and wild management of D. mawii. In broader terms, this study will contribute to our understanding of life-history strategies of herbivorous reptiles.

Green turtle spatial distribution, abundance and habitat models in the Northeastern Gulf of Mexico.	August 2021	Understanding the distribution and habitat requirements of threatened species is one of the keys to managing their recovery. Threatened juvenile green turtles (Chelonia mydas) recruit to shallow lagoons, bays and estuaries in Florida, yet, in many areas, we lack key information about their distribution, abundance and specific habitat requirements. A number of indicators suggest green turtles are recovering in the North Atlantic after centuries of human exploitation. However, the nearshore habitats they depend upon are rapidly changing through human-induced regime shifts and climate change. The Sea Turtle Conservancy, one of the world's oldest and most respected sea turtle NGOs, is collaborating with the University of Florida and the Florida Cooperative Fish and Wildlife Research Unit to study green turtles in the northeast Gulf of Mexico. The main goals of this research are to develop a habitat model that predicts green turtle abundance and understand their health, diet and movement patterns in the region. This work will inform federal and state wildlife managers on the important link between juvenile green turtles and their habitat in one of the largest remaining seagrass beds in the Gulf of Mexico.

Impacts of translocation on a cooperatively breeding bird in Ocala National Forest	June 2020	Translocation has been considered as a conservation tool to increase the population numbers of Florida scrub-jays, especially in areas that have been recently restored, and where small, isolated populations reside and are unlikely to increase naturally through dispersal. The majority of translocation research has focused on the success at recipient sites, while the impacts associated with the donor population have not been monitored. Ocala National Forest is home to the largest remaining population of Florida scrub-jays and is currently the donor site for translocations. As the goal of any translocation is to have a positive impact on the species population, it is imperative that the costs to the donor population are minimized to the greatest extent possible. This study intends to focus on the impacts that translocation could place on the donor population through monitoring of nesting success and productivity. During two field seasons, a subset of helpers will be removed from groups for translocation. Nests will be monitored within three categories of family groups: (1) no helpers, (2) helpers, (3) helpers removed. Data will be collected on productivity, nest success, weight of nestlings, time spent provisioning, and breeder persistence. Monitoring nests in groups with and without helpers will increase the understanding of how this cooperative breeder benefits from the presence of non-breeding individuals. If data show evidence that helpers do not increase productivity or nest success, then future translocations can focus on removing helpers as opposed to entire family groups.

Overwintering survival of shorebirds on Florida's Panhandle	December 2020	The beaches and coastal bayside wetlands along Florida’s panhandle are important to migrant and resident shorebirds, including species of conservation concern including Piping Plovers (Charadrius melodus) and Red Knots (Calidris canutus). Human disturbance and development, dredged and hardened inlets, and sea level rise have impacted much of the natural beach habitat in this region. Systematic surveys for non-breeding shorebirds have taken place either biweekly or monthly for the past 3-5 years. The objectives of this study are to use existing data and collect additional field data to:<br>(1) summarize/analyze regional data on non-breeding shorebirds using public lands along Florida’s Panhandle region, and (2) where data on banded birds permits, determine overwintering survival of select species (e.g. Piping Plover, Red Knot) at targeted sites along NW Florida beaches. This work will inform managers of potential areas that may need additional protection or alternative management to enhance survival of migrating and overwintering shorebirds.<br>	The beaches and coastal bayside wetlands along Florida’s panhandle are important to migrant and resident shorebirds, including species of conservation concern including Piping Plovers (Charadrius melodus) and Red Knots (Calidris canutus).

Composition, distribution and ecology of the Nature Coast sea turtle assemblage	August 2020	Initial objectives: 1) Visual transect surveys using a surface vessel will identify areas of high occurrence and will be conducted with methods similar to the work of Inwater Research Group (2012), but with the addition of line transects with distance sampling to account for detectability issues. 2) Polling of fishers and recreationists will provide a survey of local knowledge to identify turtle “hotspots”. Some of the impetus for the proposed work comes from the recent rise in anecdotal reports of the increased presence of sea turtles in coastal areas adjacent to the NCBS. 3) Aerial transects with Box on Strut (BoS)/Aerial transects with Unmanned Aerial Systems (UAS) – will leverage the research interests of the UF Unmanned Aerial Systems Research Program to perform BoS and Nova 2.1 (fixed-wing platform) flights. Resulting imagery will address the efficacy of these tools for aquatic megafaunal surveys, and provide additional data for demographic analyses. 4) Assessment of nearshore bottom types and health with tethered Remotely Operated Vehicle (ROV) transects and sampling – will allow examination and possible correlation of edaphic factors driving prey/forage availability and habitat selection. 5) Overlay of climatic data on historical and current sea turtle distribution and assemblage composition – will investigate the role of climate/SST and related variability on species distribution and dominance. This may allow examination of the hypothesis that localized increases in turtle sightings may reflect responses to changing conditions and are not solely an indication of increased populations.

Migration Trends for King and Common Eiders and Yellow-billed Loons Past Point Barrow in a rapidly changing environment	December 2018	Most of the king (Somateria spectabilis) and common eiders (S. mollissima v-nigra) and yellow-billed loons (Gavia adamsii) nesting in northern Alaska and northwestern Canada migrate twice-annually past Point Barrow, Alaska during their northward spring migration and their southward fall migration. In 1996, spring and fall counts indicated both eider species experienced population declines of approximately 50% between 1976 and 1996. The counts were repeated in 2002-2004, at which time it appeared that since 1996 the number of common eiders passing Point Barrow had increased, but only slightly, and that the number of king eiders had remained stable but had not come back to the 1970 levels. Loon species were also counted in the surveys in 2002-2004, but data have not been analyzed. The Wildlife Conservation Society (WCS) and the North Slope Borough (NSB) successfully completed a spring count in 2015 and propose to repeat the spring migration count in 2016. Our objectives are to: (1) obtain estimates of king and common eider populations to be analyzed with the current 2015 count and that can be compared with those from 1970s, 1996 and the early 2000s in order to evaluate long-term and current trends; (2) evaluate observer error through photographic and radar techniques; and (3) obtain estimates of yellow-billed loon populations that can be compared to the previous counts. Such data is critically needed in order to assess conservation needs of these species, both now and in the future.

Wader Study 128(3): 265-273. doi:10.18194/ws.00256 \| Abstract	December 2021	Shorebirds have been banded for decades and monitoring programs have helped to accumulate large band-encounter datasets from across the globe; however, many of these datasets are left largely unused, particularly those collected by citizen scientists. These datasets can provide valuable insight into<br>the migration and movement strategies of shorebirds and the threats they face throughout their migratory cycle. We used long-term (2003–2018) band-encounter data of Red Knots Calidris canutus rufa in North America to determine: (1) the spatiotemporal distribution during the nonbreeding season, (2) site fidelity to nonbreeding sites, and (3) migratory connectivity of knots using the southeastern United States (Southeast), an important overwintering and stopover area for this subspecies. Annual mean site fidelity ranged from 0% to 86% across 24 sites. We found movement between sites across the Southeast during migratory and wintering periods, indicating that knots are using the region as interconnected sites, as opposed to relying on a single site or a cluster of adjacent sites. We identified ‘hop migration’ as a common strategy for knots in the region, and showed regular within-year movement between sites in South Carolina, Georgia,<br>and Florida. The Southeast is an understudied part of the rufa range; our results show the importance of the region to the subspecies both as a stopover and wintering area. Despite the inherent biases in the data and imperfect detection due to inconsistent survey effort, the data showed large-scale movements and confirmed the region as a complex of sites connected by knots.

Using systems thinking to inform management of imperiled species: a case study with sea turtles. Biological Conservation 260: 109201 \| Abstract \| Publisher Website	June 2021	Management of imperiled species facing spatiotemporally dynamic threats is difficult. Systems thinking can inform their management by quantifying the impacts that they face. We apply systems thinking to the Northern Gulf of Mexico (NGM) loggerhead (Caretta caretta) Recovery Unit (RU), one of the smallest subpopulations of loggerheads nesting in the USA. We characterized disturbances to nests, management actions, and hatchling production across 12 nesting beaches used by this RU to explore how hatchling production would increase if disturbances were mitigated. Annual hatchling production at sites ranged from 470 to 18,191 hatchlings/year. Wash overs (19.3% nests/year), washouts (17.9% nests/year), and predation (13% nests/year) were the most common annual disturbances across sites. Focusing on the most impactful disturbances at just five sites could increase annual NGM RU hatchling production by 2.2–6.7%. Efforts to mitigate wash overs and washouts are ongoing in Alabama, but these may be futile against tropical cyclones, which accounted for >80% of washouts in the present study, and further require careful examination of associated adverse side-effects. Efforts to mitigate predation are common throughout this RU, but require improved knowledge of predator ecology to reach full potential. Systems thinking allowed us to create a simple model for assessing disturbances and management strategies in terms of hatchling sea turtles. This model can be augmented to run dynamic simulations of how disturbances and management actions impact hatchling production, and can be applied to other species with similar reproductive strategies.

Expanded mitochondrial control region sequences increase resolution of stock structure among North Atlantic loggerhead turtle rookeries. Marine Ecology Progress Series,. 469:145-160. \| Abstract	July 2012	The southeastern USA hosts the largest nesting concentration of loggerhead turtles Caretta caretta in the Atlantic. Regionally significant nesting also occurs along the Caribbean coast of Mexico, in Cuba, and in the Bahamas. Previous studies of North Atlantic loggerhead turtle rookeries based on a 380 bp fragment of the mitochondrial control region supported recognition of 8 demographically independent nesting populations (management units) in the Northwest Atlantic in addition to Cape Verde in the eastern Atlantic. Recent analysis of expanded mitochondrial control region sequences revealed additional genetic diversity and increased population structure between western and eastern Atlantic loggerhead turtle rookeries. We sequenced an 817 bp mitochondrial DNA fragment in 2427 samples from nesting beaches in the southeastern USA, Cay Sal Bank, Bahamas, and Quintana Roo, Mexico. Pairwise F-ST comparisons, pairwise exact tests of population differentiation, and analysis of molecular variance support previously proposed management unit designations and additionally indicate that southeastern and southwestern Florida rookeries should be recognized as distinct management units. Therefore, Northwest Atlantic loggerhead turtle rookeries can be subdivided into 10 management units, corresponding to the beaches from (1) Virginia through northeastern Florida, (2) central eastern Florida, (3) southeastern Florida, (4) Dry Tortugas, Florida, (5) Cay Sal, Bahamas, (6) southwestern Cuba, (7) Quintana Roo, Mexico, (8) southwestern Florida, (9) central western Florida, and (10) northwestern Florida. We confirmed increased resolution of stock structure between many Northwest Atlantic management units and the Cape Verde rookery with the expanded control region haplotypes.

Fisheries bycatch of non- target species in the commercial fleet is a major source of anthropogenic injury and mortality for sea turtles and marine megafauna. 2. The Río de la Plata, Maritime Front (RLPMF) and its adjacent international waters - comprising part of the Argentine and Uruguayan exclusive economic zones (EEZs), is a highly important fishing ground in the South-western Atlantic Ocean (SWAO) as well as feeding and development grounds for sea turtles. 3. This paper analyses the distribution of the bottom and pelagic trawling fishery within the RLPMF using information from Vessel Satellite Monitoring System (VMS). With this information, areas of highest trawling intensity were defined and further evaluated their overlap with sea turtle habitat-use areas from available sea turtle satellite tracking information.4. Results besides identifying high-susceptibility areas for sea turtle bycatch by the commercial trawler fleet along the RLPMF, provide predictive tools to identify vulnerable areas to interaction of sea turtles and the commercial fishing fleet.5. Implementation of bycatch mitigation measures, such as reduced fishing effort areas by the Argentine and Uruguayan fisheries management agencies has the potential to benefit the fisheries as well as marine megafauna. Furthermore, there is a need for additional research on the impact this fleet can have on sea turtles present in the area.<br><br>

Marine Ecology. 15pp IP- 068594. https://doi.org/10.1111/maec.12412 \| Abstract \| Publisher Website	April 2017	Grande Riviere beach, on the island of Trinidad, supports the largest nesting population of leatherback turtles in the Caribbean region. Throughout the nesting season, nests are naturally disturbed by newly nesting females, resulting in egg breakage and loss of some nest viability. This environment is ideal for the growth and proliferation of microorganisms. The range of bacterial flora present in beach sand and egg shells was examined, with emphasis on bacteria that may pose a threat to public and animal health. The extent to which the bacterial load and genera on the beach changed throughout the season was also assessed. Twenty-five genera were identified, with Pseudomonas spp. found to be the most predominant environmental bacteria. Four genera identified possess zoonotic potential, while five additional genera are known to be of public and animal health significance. Distinct shifts in the density and distribution of bacteria were observed along the beach from early to peak nesting season. Shifts were seen across heavily traversed zones, thus highlighting the potential exposure threats posed to beach visitors and animals alike. Further studies aimed at speciating this population of bacteria, as well as isolating potential fungal pathogens may mitigate this threat. Identification of bacterial agents that are specifically pathogenic to leatherback turtles, turtle eggs, hatchlings and those who may interact with these animals will serve to enhance and guide efforts to better conserve this species and protect the health of all who visit this ecologically significant site.

The Open Ecology Journal. 5: 25-44. \| Abstract	October 2012	The line transect distance sampling method provides unbiased estimates of abundance when organisms are distributed randomly or line transects are laid out randomly, sample sizes are large and other assumptions of the method are met; such, however, is rarely the case in real life. We conducted a simulation study to investigate how spatial distribution and density of objects, and total length, layout and number of transects influence bias, precision, and accuracy of estimates of abundance obtained by distance sampling along line transects. Overall, density estimated using the distance sampling method was within 4.9% of the true density, but it varied substantially depending upon spatial distribution of objects. Of the three spatial distribution patterns considered, estimates of density were least biased, and most precise and accurate when objects were distributed randomly; they were most biased, and least precise and accurate when objects followed a clumped distribution. The estimated bias (% difference between true density and estimated density) for clumped, random and uniform distribution was 13.1%, -0.4%, and 2.1%, respectively; precision (% coefficient of variation, CV( D ˆ )) was 13.7%, 9.1%, and 9.2%; and accuracy (root mean-squared error, RMSE) was 27.9%, 7.4%, and 11.7% for clumped, random, and uniform distribution, respectively. Increasing total transect length and using several short transects (as opposed to few long transects) generally reduced bias, and increased accuracy and precision of estimates of abundance. A systematic layout of transects worked as well as, or better than, random layout, except when objects were distributed uniformly in space. This study advances the utility of the line transect method by providing information both on how study design affects accuracy and precision of abundance estimates, and how it can be improved when assumptions of the method are not strictly met based on a priori knowledge of the spatial distribution and presumed density of the target organism through appropriate changes in the study design.

Marine Biology. 161:2659–2668 DOI 10.1007/s00227-014-2537-0 \| Abstract	September 2014	Because subpopulations can differ geographically, genetically and/or phenotypically, using data from one subpopulation to derive vital rates for another, while often unavoidable, is not optimal. We used a two-state open robust design model to analyze a 14-year dataset (1998-2011) from the St. Joseph Peninsula, Florida (USA; 29.748°, -85.400°) which is the densest loggerhead (Caretta caretta) nesting beach in the Northern Gulf of Mexico subpopulation. For these analyses, 433 individuals were marked of which only 7.2 % were observed re-nesting in the study area in subsequent years during the study period. Survival was estimated at 0.86 and is among the highest estimates for all subpopulations in the Northwest Atlantic population. The robust model estimated a nesting assemblage size that ranged from 32 to 230 individuals each year with an annual average of 110. The model estimates indicated an overall population decline of 17 %. The results presented here for this nesting group represent the first estimates for this subpopulation. These data provide managers with information specific to this subpopulation that can be used to develop recovery plans and conduct subpopulation-specific modeling exercises explicit to the challenges faced by turtles nesting in this region.

Global Ecology and Conservation 23: https://doi.org/10.1016/j.gecco.2020.e01070 \| Abstract \| Publisher Website	September 2020	The warming climate presents a challenge to conservation of all threatened and endangered species but particularly to those that exhibit temperature-dependent sex determination such as sea turtles. Changes in temperature may result in changes in the sex ratio of the population which can directly affect reproductive rate, abundance and population dynamics. The NW Atlantic loggerhead turtle population is listed as threatened under the U.S. Endangered Species Act, and one of the smallest subpopulations in this assemblage nests in the northern Gulf of Mexico. Here, we describe the incubation environment of northern Gulf of Mexico loggerheads nesting at several different beaches in Northwest Florida. Temperature dataloggers were placed inside and adjacent to nests on different nesting beaches across Northwest Florida. In addition, incubation durations were recorded from nests deposited on those same beaches. Internal nest temperatures were higher than those in the sand, however sand temperatures were correlated with incubation durations. Sand temperatures differed along the vertical beach profile and according to depth. Temperatures also differed along a geographic gradient across Northwest Florida and in relation to distance from the Apalachicola River. Incubation durations followed a similar pattern. Mean monthly temperatures at all sites were at or lower than 29 °C (range 23.1 °C–29.6 °C at the dunes; 23.8 °C–29.4 °C at mid-beach) which suggests nests in Northwest Florida may be producing a significant number of males, in contrast to the large number of females being produced on Florida’s Atlantic coast. The temperatures and incubation durations on these nesting beaches may be regulated by differing sources of sand and beach orientations across Northwest Florida. <br><br>

Environmental factors predicting the orientation of sea turtle hatchlings on a naturally lighted beach: A baseline for light-management goals. Journal of Experimental Marine Biology and Ecology 541 (2021) 151568. \| Abstract	May 2021	On sea turtle nesting beaches, artificial lighting associated with human development interferes with hatchling orientation from nest to sea. Although hatchlingdisorientation has been documented for many beaches, data that managers can use in understanding, predicting, and managing the issue are of limited detail. Thepresent study provides baseline hatchling orientation data that can be compared to those from beaches with artificial lighting to prioritize light-management effortsthere. In 2014, the precision of hatchling orientation was quantified for 87 nests on a naturally lighted beach that had little to no artificial lighting. Precision ofhatchling orientation was regressed against seven environmental variables: beach slope, distance from nest to dune, dune height, apparent dune silhouette heightrelative to nest site, moon illumination percentage, cloud cover percentage, and relative humidity. Results favored a regression model that included distance fromnest to dune, with shorter distances from the dune predicting a narrower angular range (i.e., greater precision) of hatchling orientation. The study confirmed findingsof an earlier laboratory experiment that highlighted the importance to accurate hatchling orientation of a dark silhouette (dune) on the side of the nest site oppositethe ocean side. Reducing artificial light and promoting the planting of pioneer plants that assist dune formation can increase hatchling survival.

Deep and machine learning image classification of coastal wetlands using unpiloted aircraft system multispectral images and lidar datasets. Remote Sensing. \| Abstract	August 2022	The recent developments of new deep learning architectures create opportunities to accurately classify high-resolution Unoccupied Aerial System (UAS) images of natural coastal systems and mandate continuous evaluation of algorithm performance. We evaluated the performance of four machine learning techniques applied to UAS multispectral aerial imagery and canopy height models (CHM) prepared using both, UAS-acquired lidar, and structure-from-motion (SfM) point clouds combined with a DTM from a publicly accessible lidar dataset. We assessed the performance of the U-Net and DeepLabv3 deep convolutional network architectures and two traditional machine learning techniques (support vector machine (SVM) and random forest (RF)) applied to seventeen coastal land cover types in the Wolf Branch Creek Coastal Nature Preserve located in west Florida. Twelve combinations of spectral bands and CHMs were used to train the classifiers. The classification algorithms were trained with a total of 3,094 polygons created from an object-based image segmentation step. A total of 747 random, ground-truth accuracy assessment points, representing all 17 classes, were used to assess the classification results. Our results using the spectral bands showed that the U-Net (83.80% - 85.27% overall accuracy) and the DeepLabV3 (75.20% - 83.50% overall accuracy) deep learning techniques outperformed the SVM (60.50%-71.10% overall accuracy) and the RF (57.40% -71.0%) machine learning algorithms. Adding the CHM to the spectral bands slightly increased the overall accuracy as a whole in the deep learning models, with some vegetation classifications benefitting from the additional information, while the addition of a CHM notably improved the SVM and RF results. Similarly, using bands outside the three spectral bands, namely near infrared and red edge, increased the performance of the machine learning classifiers with minimal impact on the deep learning classification results. The difference in the overall accuracies produced by the use of UAS-based lidar and SfM point clouds, as supplementary geometrical information, in the classification process were minimal across all classification techniques. Our results highlight the advantage of using deep learning networks to classify high resolution UAS images in highly diverse coastal landscapes. We also found that low-cost, three-visible-band imagery is feasible without risking a significant reduction in the classification accuracy when deep learning models are adopted.
Goforth, K. M. and R.R. Carthy. 2022. Tidally-driven gas exchange in beaches: implications for sea turtle nest success. Journal of Coastal Research. doi.org/10.2112/JCOASTRES-D-21-00082.1 \| Abstract	February 2022	The success of individual sea turtle nests is influenced by nest location on the beach and the resulting incubation environment. Several abiotic factors affect nest incubation, and thus nest success, but tides and gas exchange are two of the most important. The effects of tides on nest success have been well documented in regard to overwash and inundation events. However, the possible effect of tidally-driven gas exchange has received little attention. The incursion and retreat of the saltwater wedge may cause substantial movement of gases through the beach during the tidal cycle. This study quantifies the differences in tidally-driven gas exchange among beach types and shoreline elevation levels. Carbon dioxide (CO<sub>2</sub>) efflux was used as a means of measuring gas movement through the beach to examine tidal effects across different beach zones and among different beach types. CO<sub>2</sub> efflux was measured throughout the tidal cycle at three distinct beaches (accreting, eroding, and nourished) at Cape San Blas, Florida. There was a general pattern of CO<sub>2</sub> efflux rising and falling throughout the tidal cycle on each beach and a difference in the CO<sub>2</sub> efflux observed among beaches and beach zones. Efflux patterns at the nourished and eroding beaches were similar, but the nourished beach exhibited a decreased and dampened CO<sub>2</sub> efflux pattern throughout the course of the tidal cycle. Analyses of the hatchling turtle emergence success data from 2011 to 2014 for the three beaches found that emergence success differed among the three beaches. The highest emergence success was on the nourished beach, which exhibited a relatively consistent efflux pattern. These results suggest that tidally-driven gas exchange may have implications on nest incubation and survival and are a consideration in beach restoration management and best practices for coastline conservation.

Ifju. 2022, The Bathy-drone: An autonomous Uncrewed drone-tethered sonar system. Drones \| Abstract	October 2022	A unique drone-based system for underwater mapping (bathymetry) was developed at the University of Florida. The system, called the "Bathy-drone," is comprised of a drone that drags, via a tether, a small vessel on the water surface in a raster pattern. The vessel is equipped with a recreational commercial off-the-shelf (COTS) sonar unit that has down-scan, side-scan, and chirp capabilities and logs GPS referenced sonar data onboard or transmitted in real-time with a telemetry link. Data can then be retrieved post-mission and plotted in various ways. The system provides both isobaths and contours of bottom hardness. Extensive testing of the system was conducted on a 5-acre pond located at the University of Florida Plant Science and Education Unit in Citra, FL. Prior to performing scans of the pond, ground truth data was acquired with an RTK GNSS unit on a pole to precisely measure the location of the bottom at over 300 locations. An assessment of the accuracy and resolution of the system was measured by comparison to the ground truth data. The pond ground truth had an average depth of 2.30m while the Bathy-drone measured an average 21.6cm deeper than the ground truth, repeatable to within 2.6cm. The results justify integration of RTK and IMU corrections. During testing, it was found that there are numerous advantages of the Bathy-drone system compared to conventional methods including ease of implementation and the ability to initiate surveys from the land by flying the system to the water or placing the platform in the water. The system is also inexpensive, lightweight, and low volume, thus making transport convenient. The Bathy-drone can collect data at speeds of 0-24 km/h (0-15 mph), and thus can be used in waters with swift currents. Additionally, there are no propellers or control surfaces underwater, so the vessel does not tend to snag on floating vegetation and can be dragged over sandbars. An area of more than 10 acres was surveyed using the Bathy-drone in one battery charge and in less than 25 minutes.

Global Change Biology, 23(11):4556-4568, http://dx.doi.org/10.1111/gcb.13712. \| Abstract \| Publisher Website	June 2017	Somatic growth is an integrated, individual-based response to environmental conditions, especially in ectotherms. Growth dynamics of large, mobile animals are particularly useful as bio-indicators of environmental change at regional scales. We assembled growth rate data from throughout the West Atlantic for green turtles, Chelonia mydas, which are long-lived, highly migratory, primarily herbivorous mega-consumers that may migrate over hundreds to thousands of kilometers. Our dataset, the largest ever compiled for sea turtles, has 9690 growth increments from 30 sites from Bermuda to Uruguay from 1973 to 2015. Using generalized additive mixed models, we evaluated covariates that could affect growth rates; body size, diet, and year have significant effects on growth. Growth increases in early years until 1999, then declines by 26% to 2015. The temporal (year) effect is of particular interest because two carnivorous species of sea turtles—hawksbills, Eretmochelys imbricata, and loggerheads, Caretta caretta—exhibited similar significant declines in growth rates starting in 1997 in the West Atlantic, based on previous studies. These synchronous declines in productivity among three sea turtle species across a trophic spectrum provide strong evidence that an ecological regime shift (ERS) in the Atlantic is driving growth dynamics. The ERS resulted from a synergy of the 1997/1998 El Niño Southern Oscillation (ENSO)—the strongest on record—combined with an unprecedented warming rate over the last two to three decades. Further support is provided by the strong correlations between annualized mean growth rates of green turtles and both sea surface temperatures (SST) in the West Atlantic for years of declining growth rates (r = −.94) and the Multivariate ENSO Index (MEI) for all years (r = .74). Granger-causality analysis also supports the latter finding. We discuss multiple stressors that could reinforce and prolong the effect of the ERS. This study demonstrates the importance of region-wide collaborations.
Bishop, N., Polisar, J., Eliazar, P.J., Carthy, R.R., & Bjorndal, K.A. 2022. Diet of Dermatemys mawii, an aquatic turtle that relies heavily on terrestrial vegetation. Chelonian Conservation and Biology. CCB1467 \| Abstract	March 2022	<i>Dermatemys mawii</i> is a critically endangered freshwater turtle endemic to Central America. In the wild, these turtles are thought to be wholly herbivorous as adults and feed on a variety of vegetation; however, no studies have quantitatively assessed potential dietary differences based on biotic and abiotic factors. The purpose of our study was to describe and quantify the wild diet of <i>D. mawii</i> and assess differences based on habitat, maturity, and sex. We evaluated the stomach contents of 66 turtles legally harvested by local hunters for personal consumption throughout the country of Belize. Percent volume (by displacement) and percent frequency of each stomach item were used to calculate an index of relative importance (IRI). One algal and six plant families contributed to an overall diet composition consisting of leaves, flowers, stems, seedpods, seeds, and fruit. Rocks and invertebrates were also consumed, although we believe these to be incidental consumption. The leaves of the riparian tree <i>Inga edulis</i> were present in 73.1% of turtle stomachs and accounted for almost half of the total volume of all stomach contents combined. We used Spearman rank correlation coefficients to test the null hypothesis that there was no correlation in the rankings of stomach items (i.e. there were differences) when comparing turtles by habitat, age, and sex. There were significant differences in the ranking of food items between river and lagoon habitats, with lagoon turtles relying heavily upon the algae <i>Nitella </i>sp.; however, the stomach contents from both habitats were equally diverse (H<sub>rivers</sub> = 1.68, H<sub>lagoons</sub> = 1.64). There were no differences in IRIs between adults and juveniles or between males and females. Our results emphasize the importance of habitat in <i>D. mawii </i>diet selection and the importance of leaves from riparian plants species that are shed into their aquatic habitats.
Bishop, N. D., Hudson, R., Marlin, J., Pop, T., Rainwater, T., Boylan, S., Atkinson, B., and Carthy, R. R. 2021. Using growth rates to estimate the minimum age and size at sexual maturity in a captive population of the critically endangered Central American river turtle Dermatemys mawii. Journal of Zoo and Aquarium Research, 9(3), 150–156. https://doi.org/10.19227/jzar.v9i3.432 \| Abstract	July 2021	The Central American river turtle (<i>Dermatemys mawii</i>) is a critically endangered species that has incurred substantial losses over the last several decades due to overhunting. This species is now being considered for head-starting programs (i.e. captive breeding of turtles for wild release). However, relatively little is known about their life history characteristics, especially with respect to growth and sexual maturation. A robust knowledge of <i>D. mawii</i> life history traits is important in developing conservation management plans. Our research is the first known study to maintain hatchlings, juveniles, and adults in captivity with regular morphometric data collection. We quantified growth rates (cm yr-1) and calculated growth parameters (e.g. growth coefficients) to estimate body size and age at onset of sexual maturity in a group of wild-caught but captive-held and captive-bred <i>D. mawii</i> in Belize. Sizes at the onset of sexual maturity were inferred by segmented linear regressions that identified changes in growth rate by body size. Asymptotic sizes and growth coefficients were calculated using the Fabens method and the Wang method. Parameters from these models were then applied to a modified von Bertalanffy growth equation to estimate age at the onset of sexual matuarity. Male and female <i>D. mawii</i> begin sexual maturation at ca. 38.0 cm and 40.0 cm straight-line carapace length, respectively. We estimated ages associated with these sizes at 13.5-16.9 yrs (males) and 13.6-17.3 yrs (females). No previous literature on growth rates or age at maturation for wild or captive <i>D. mawii</i> has been reported, so our results serve as a starting point in conservation management. Given the life history trait of delayed sexual maturity (>10 years), <i>D. mawii</i> may be more sensitive to losses of the adult population. Therefore, the importance of captive breeding and head-starting programs is concomitant with protecting wild, adult populations.

Tuma, M. E. and A. N. Powell. Movement and Distribution of Red Knots (Calidris canutus) in the Southeastern U.S. Western Hemisphere Shorebird Group, Panama City, Panama	October 2019	The Southeastern U.S. is an important nonbreeding area for Red Knots, supporting migratory and overwintering populations. Studies indicate possible regional declines and shifts in distribution in the knot population in the Southeast; however, most studies have focused on subregions of the Southeast, leaving questions about use and connectivity across the region as a whole. Using over a decade of data from ebird and band resightings from bandedbirds.org, we examined: (1) movement strategies of knots in coastal areas from Texas to North Carolina, and (2) the distribution of knots across that range and what drives that distribution.

Smith, R. S., S. Schaf, and R. R. Carthy. 2023. Entanglement of marine turtles in Florida’s commercial and recreational trap fisheries: 30+ years of data reveal a potentially ubiquitous and persistent threat. Oral presentation at International Sea Turtle Symposium, Cartagena, Colombia.	March 2023	Incidental bycatch is considered to be among the most significant threats facing marine turtle populations. Given the ubiquity of entanglement records across Florida, coupled with most entanglement events being reported in the absence of a recognized on-the-water observer network, the threat posed to marine turtles by trap fishery gear entanglement is likely substantially underreported and underrepresented.

Robinson, B., L. Phillips, and A. Powell. 2017. Accelerated energy intake increases survival rates of Black Oystercatcher broods. Annual Meeting, Pacific Seabird Group, Tacoma, WA.	February 2017	To determine the importance of diet on brood survival, we modeled daily survival rates of broods as a function of energy intake rate and other ecological factors. Delivery rates differed by age, however, the composition and size classes of prey fed to chicks by their parents did not, indicating that adults respond to the energetic needs of broods by increasing parental effort rather than switching prey.

Implications for long-term monitoring of Black Oystercatchers. 6th Western Hemisphere Shorebird Group Meeting, Wallops Island, VA.	September 2015	The collection of prey remains at nest sites is a widely-used method for estimating diet of Black Oystercatcher chicks. However, we found estimates are biased on prey body type and nesting habitat, and alternative methods should be considered.
Robinson, B. H., L. M. Phillips, and A. N. Powell. 2016. Accelerated energy intake increases survival rates of Black Oystercatcher broods. NPS Centennial Science and Stewardship Symposium, Fairbanks, Alaska.	October 2016	To understand the relationship between Black Oystercatchers and the prey on which they depend, we studied their diet, feeding rates, brood growth and survival in Kenai Fjords National Park in 2013 and 2014. Adults responded to the energetic needs of broods by increasing parental effort rather than switching prey, and broods that were fed more had higher survival rates.
Robinson, B. H., L. M. Phillips, and A. N. Powell. 2016. Accelerated energy intake increases survival rates of Black Oystercatcher broods. Alaska Chapter, TWS, Anchorage, Alaska.	March 2016	We found that energy intake was directly related to chick survival in Black Oystercatchers. Increased demands by growing chicks were met through increased provisioning rates by adult birds and not by changing prey type or size class.

Oral presentation at International Sea Turtle Symposium, Cartagena, Colombia.	March 2023	Frequent outbreaks of fibropapillomatosis in recent decades are likely attributable to external drivers such as large-scale anthropogenic changes in the green turtle coastal marine ecosystem. This study found that variations in sea surface temperature, salinity, and nutrient effluent discharge from nearby rivers were correlated with an increased incidence of the disease, substantiating that these may be among the significant environmental drivers impacting Fibropapillomatosis prevalence.

Cardas, Alexis, Abby Powell, and Karl Miller. (2021) Impacts of translocation on the cooperatively breeding Florida scrub-jay in Ocala National Forest, Friday Findings Webinar, USGS Ecosystems Mission Area.	March 2021	<b>Key Messages (What takeaways do you want the audience to have?): </b><br>Donor site/population monitoring should be built into future translocation projects. I realize that some species can be quite cryptic in the wild, but some degree of post-translocation monitoring should be prioritized when creating/implementing research protocols.Continue Florida scrub-jay research in Ocala National Forest as this site contains the largest remaining population while having the least amount of research conducted there. <b><br> Background/Abstract (Issue, Why USGS): </b><br>Translocation has been considered as a conservation tool to increase the population of threatened and endangered species, especially in areas that have been recently restored, and where small, isolated populations reside and are unlikely to increase naturally through dispersal. Most translocation research has focused on the success at recipient sites, while the impacts associated with the donor population have not been rigorously monitored. Ocala National Forest is home to the largest remaining population of Federally Threatened Florida scrub-jays. As the goal of any translocation is to have a positive impact on the species population, it is imperative that costs to the donor population are minimized to the greatest extent possible. I studied nesting success and productivity at donor sites to assess the impact of translocation. Our goal was to determine whether the removal of helpers from family groups of Florida scrub-jays is a viable option for future translocations. We removed a subset of helpers from family groups for translocation January-July of 2018 and 2019. We monitored three categories of family groups: (1) no helpers (<i>n=</i>59<i>)</i>, (2) helpers (<i>n=</i>34<i>)</i>, (3) helpers removed (<i>n=</i>10<i>)</i>. We recorded nest success, mass of nestlings at age day 11, and time spent provisioning (recorded by nest cameras). Overall, productivity and nestling weights were higher in 2018 than 2019 but we found no significant difference in nestling mass between group categories (no helpers and helpers present). The best-supported model in predicting the daily survival rate of Florida scrub-jay nests included the additive effects of linear date within breeding season and year. We found little support for group size (helper, no helper) as a factor to be predictive of daily survival rate. Our results suggest that the presence of non-breeding helpers has less of an effect on nestling mass, productivity, and nest success than the factors of year and linear date within season. Our data suggests that removing helpers is a viable option for future translocation efforts of Florida scrub-jays. In addition to concurrent research conducted at the recipient sites, this will be an important first step towards the initiation of a statewide translocation protocol for Florida scrub-jays.<br> <br><b>Presentation has been reviewed by (CD & Direct Supervisor must approve of presentation): </b><br>Abby Powell, UL of the Florida Cooperative Fish and Wildlife Research Unit and graduate advisor of Alexis Cardas

February 2017	Most of the king and common eiders nesting in northern Alaska and northwestern Canada migrate past Point Barrow, Alaska, during spring and fall migration. Spring migration counts have been conducted approximately every ten years at Point Barrow since 1976, and indicated that both eider species experienced population declines of approximately 50% between 1976 and 1996, and that the declines had stabilized by 2004. We conducted spring counts in 2015 and 2016 to obtain population estimates that can be compared with those from 1970s, 1996, and the early 2000s in order to evaluate long-term and current trends
