Black (Haliotis cracherodii) and white (H. sorenseni) abalone are closely related phylogenetically and are among the first marine invertebrates to be listed as "endangered" pursuant to the US Endangered Species Act of 1973 as amended. However, the two species have strikingly different population biology and habitat use patters, face very different risk factors, and will require differing and independent actions by management agencies for successful recovery.

We used stable isotope mixing models to estimate, for several species of nearshore fish and crab in two areas of North Puget Sound, Washington, the percent diet originating from eelgrass meadows, pelagic planktonic sources, and oyster farm habitats. Our results indicate that several species of nearshore fish derive a significant proportion of their diets from farm areas, while others derive most of their diets from eelgrass habitat or planktonic sources.

February 2016
|
Poorly understood diseases have influenced populations of three different high-profile coastal marine invertebrate species at San Nicolas Island, California in 2015 and 2016, and an unprecedented coincident generalized physical disturbance has negatively influenced populations of all three species. The confluence of such events is a challenge to simple top-down trophic models in coastal marine ecosystems, complicating the management and conservation of such systems.

Sea otters are widely recognized in the technical literature as important apex predators, and there has been virtually no investigation of potential impacts of bottom-up ocean forcing mechanisms on the dynamics of sea otter populations. Sea otters and black abalone both occur at San Nicolas Island, and an observed (and surprising) positive correlation of sea otter and abalone numbers at SNI since 2001 indicates an important positive role for recent cold-phase ocean dynamics in recruitment succ

Avian egg size reflects maternal investment, and is a life history variable that may be sensitive to environmental conditions. We found that egg size in a seabird, the Scripps Murrelet, in the Channel Islands is related to oceanic conditions, which may provide another mechanism through which changing ocean conditions influence populations.

We developed a multipopulation IPM for Pacific salmon (Oncorhynchus spp.) that accounts for spatial and temporal variability in adult recruitment and age structure, the presence of hatchery-origin spawners, and observation error in abundance, age-composition, and hatchery-fraction data. We have applied the model to data for three different species of salmon in Idaho, Washington, and Oregon, which has illuminated the varying effects of harvest, hatchery influences, freshwater flows, and large-sc

|
August 2022
|
Effective conservation of at-risk species requires an understanding of trends in abundance over time, but in many cases the data necessary to estimate population trajectories are often quite noisy and incomplete. I used a hierarchical state-space model to estimate trends over time for 242 populations located in 62 core areas spread across the Pacific Northwest; approximately 60% of the core areas showed a decreasing trend over time, but only 5% of the core areas had significant declines.

Pigeon Guillemots have been identified as ecosystem indicators, or Vital Signs, in the Puget Sound by the Puget Sound Partnership, a state agency formed in 2007 to coordinate restoration of Puget Sound. The use of these seabirds as Vital Signs is only as powerful as our understanding of how they respond to their environment, however. This research will address missing knowledge regarding the relationship between marine conditions in their foraging habitat.

|
Body size can affect species’ foraging success and efficiency, and males of most seabird species are larger than females. We studied foraging efficiency in a penguin with a sex ratio that is skewed towards males, and found that not size but other sex-specific foraging behaviors are driving large differences in foraging success and potentially mortality rates.

We investigated the sensitivity of management decisions to unknown dynamics regarding colonization of sites by the pathogenic chytrid fungus using value of information and regret analyses. We found that, while uncertainty is substantial, the optimal decisions vary little, suggesting that little management value would be gained by reducing this uncertainty before moving to conserve the boreal toad.

Spatial capture-recapture (SCR) models have become widespread for estimating demographic parameters but tend to rely on unrealistic assumptions about animal movement. Herein, we describe SCR-movement models that integrate animal movement processes into SCR models and demonstrate how to formulate, simulate from, and fit this new class of models.

We found that riverine NO3- concentration, yield, δ15N and δ18O patterns were best defined by two river groupings associated with the two regional mountain ranges (Cascade vs. Olympic<br>mountains), and that hydrologic and climate variables best explained variation in NO3- concentration and yield. These results highlight that while regional-scale climate controls N delivery, finer-scale features at the watershed level play a distinct role in driving N sources.

Seabirds are one of the most highly imperiled groups of birds. Despite this, a disproportionate amount of seabird research focuses on the role of seabirds as ecosystem indicators. Science is needed to advance conservation of the birds themselves. I will demonstrate how a decision-analytic framing can help to ensure that the science we do is maximally relevant to decision makers, and has the greatest potential to effect positive conservation outcomes for seabirds.

|
Synchrony in the demographic rates of spatially structured populations has important implications for population viability, while reflecting the scale at which environmental conditions shape populations. We investigated synchrony in survival in the Common Murre (Uria aalge) in the Baltic Sea, and our results indicate the Murre populations appear to be responding to large-scale forces shaping conditions in the Baltic, which has implications for long-term trajectories for this population.

Monitoring invasive species to learn about their populations is key to making effective management decisions, but sampling efforts are oftentimes limited by the cost of implementing such monitoring. We simulated various candidate monitoring scenarios for invasive brown treesnakes in order to identify a suite of Pareto-efficient scenarios managers may choose from to accurately estimate brown treesnake snake abundance while minimizing cost in areas targeted for suppression.

This works summarizes simulation work we did to assess if the abundance of brown treesnakes can be estimated accurately, precisely, and without bias if non-consumptive lures are used to obtain observations of brown treesnakes (BTS) on camera traps. We found that regardless of camera density on the landscape, lure attraction resulted in poorly estimated BTS abundances; however, even when no lure was used, abundance estimates were still inaccurate, imprecise, and biased. Additional monitoring met

We simulated snake movement to better understand the way lure-attraction and camera trap density can influence abundance estimates of brown treesnakes. We found that with the highest lure-attraction and lowest number of cameras, density estimates were highly biased and imprecise under all models.

Early detection and rapid response (EDRR) to the introduction or spread of an invasive species is key to the prevention of establishment or success of eradication. We evaluate two methods (the use of mouse lures and spray scent) for increasing the detection probability of invasive brown treesnakes during visual surveys as a potential tool for EDRR. We found that use of mouse lures can increase detection of brown treesnakes while spray scent actually lowers detection probability.
