Seagrass, saltmarsh and oyster reefs are recognized as Essential Fish Habitats in coastal waters of the U.S. because they support high densities of juvenile fish and invertebrates. Yet the degree to which this juvenile enhancement results in increased fish biomass at a landscape scale remains poorly quantified. Here we present results from an analysis of a large database of habitat specific juvenile densities, collated from the published literature as well as coastal state fisheries independent

@e evaluated surface water dynamics of 29 historically important wetlands in the Chihuahuan Desert of Mexico to migratory waterbirds by reconstructing a 36-year (1984-2019) time series of seasonal (October-March) surface water extent via remote sensing. Our results provide quantitative insight into patterns and trends in surface water availability and inform where restoration and protection efforts may be most beneficial.

The Eastern Oyster is an important bivalve species in coastal Louisiana due to its role as an ecosystem engineer and its high commercial value. Managers seek to identify ideal environments for larval growth, settlement and growth to adulthood but often lack the integrated tools. Here, we couple hydrodynamic and water quality models with larval growth simulation to predict larval survival and growth under different environmental conditions.

We evaluated the accuracy of Bortolloti’s formula on 28 post-fledging Bald Eagles from Louisiana, and upon documenting numerous misclassifications (21.4%), used discriminant analysis to develop a new formula applicable to Louisiana and other southern Bald Eagles.

Seagrass promote coastal resilience, but are declining globally. We develop a suitability model for the dominant species on Guam, an island in the Pacific vulnerable to climate change. The model can help identify suitable areas for restoration, and can identify how changing climate will affect the distribution of enhalus.

|
Restoration of breeding islands for colonial nesting waterbirds is extremely expensive, thus data are needed to assist in determining minimum elevations necessary to sustain nesting success. In this study, we evaluate nesting success of four colonial nesting waterbird species as it relates to flood probabilities in coastal Louisiana.

Colonial nesting waterbirds often use low-lying coastal islands for nesting and overwash events can cause substantial mortality. In this study, we determine the effects of elevation on several colonial nesting waterbird species to assist in the identification of target elevations for island restoration.

Eastern oysters form a vital part of east coast and Gulf of Mexico estuarine ecosystems. In Louisiana, where oysters support a large commercial industry, and form the basis of extensive coastal restoration projects, declining production trends have resulted in concerns about population sustainability. Oyster demography (i.e., how many large oysters) and environmental conditions influence reproductive capacity, which is essential for sustainable oyster populations. This study aims to examine the

Louisiana's coast is rapidly eroding due to multiple natural and anthropogenic stressors.

Our results provide insight into the direct effect of the mussels on shoreline strength and stability and if these effects are density dependent. Understanding the dynamic relationship between G. granosissima and S. alterniflora is a critical precursor to the use of ribbed mussels for shor

The oyster industry is increasingly relying on triploid oysters to boost production. Despite their growth advantage, reports of elevated triploid mortality compared to diploids cause significant concern to oyster growers. Here, we test the effects of extreme salinity and temperature on diploid and triploid survival rates in the lab, to explore potential differences in responses by ploidy.

|
February 2024
|
Spring migrations are an integral part of the annual cycle for most waterfowl species, thus we investigated the potential effects of several environmental factors on blue-winged teal (<i>Spatula discors</i>) spring migration phenology during 2020 – 2023. We hypothesize that photoperiod will explain the greatest variation in migration initiation date, but there is limited research on other factors that may influence initiation from wintering grounds and subsequent migratory movements.

Migratory events are an integral part of the annual cycle for most waterfowl species, thus we investigated the potential influence of dynamic wetland availability on blue-winged teal (<i>Spatula discors</i>) resource selection from 2019-2024. We hypothesized that blue-winged teal would specifically move to and select for proximal areas with greater wetland availability during both spring and autumn migration. This research can inform wetland management and conservation in support of blue-winged teal.

This study used band recovery data to esitmate annual survival,recovery rates, and the process correlation between to assess whether hunting mortality was additive to other mortality factors. The results will provide useful information for waterfowl managers concerned with population modelling of lesser scaup and other ducks.

|
Impoundments are a common tool for waterfowl management in coastal systems, but on organic soils, drawdowns associated with the management can lead to loss of elevation and make the impoundments susceptible to sea level rise. In this study, we evaluate accretion and decomposition mechanisms and their effects on elevation gain and loss in coastal impoundments.

Hydrologic modifications of floodplain forests in the southeast have intensified drought conditions, thus making drought tolerance of increased significance in regeneration of these forests. In this study, we evaluate biomass allocation patterns in seedlings of several bottomland hardwood species to infer interspecific drought tolerances.
