Prey Patch Patterns Predict Habitat Use by Top Marine Predators with Diverse Foraging Strategies

Creator:: Benoit-Bird, Kelly J., Battaile, Brian C., Heppell, Scott A., Hoover, Brian, Irons, David, Jones, Nathan, Kuletz, Kathy J., Nordstrom, Chad A., Paredes, Rosana, Suryan, Robert M., Waluk, Chad M., and Trites, Andrew W.
Abstract:: Spatial coherence between predators and prey has rarely been observed in pelagic marine ecosystems. We used measures of the environment, prey abundance, prey quality, and prey distribution to explain the observed distributions of three co-occurring predator species breeding on islands in the southeastern Bering Sea: black-legged kittiwakes (Rissa tridactyla), thick-billed...

Utilizing Fishermen Knowledge and Expertise: Keys to Success for Collaborative Fisheries Research

Creator:: Yochum, Noelle, Starr, Richard M., and Wendt, Dean E.
Abstract:: Collaborative fisheries research provides a mechanism for integrating the unique knowledge, experience, and skills of fishermen and scientists. It is a joint intellectual endeavor that begins with the inception of a project and continues until its final stages, with each group having mutual investment in-and ownership of-the project. Collaborative fisheries...

Survival and behavior of juvenile steelhead trout (Oncorhynchus mykiss) in two estuaries in Oregon, USA

Creator:: Romer, Jeremy D., Leblanc, Camille A., Clements, Shaun, Ferguson, Jayde A., Kent, Michael L., Noakes, David, and Schreck, Carl B.
Abstract:: Anadromous salmonids are viewed as a prized commodity and cultural symbol throughout the Pacific coast of North America. Unfortunately, several native salmonid populations are threatened or at risk of extinction. Despite this, little is known about the behavior and survival of these fish as the juveniles transition from freshwater to...

Increasing Thiamine Concentrations in Lake Trout Eggs from Lakes Huron and Michigan Coincide with Low Alewife Abundance

Creator:: Riley, Stephen C., Rinchard, Jacques, Honeyfield, Dale C., Evans, Allison N., and Begnoche, Linda
Abstract:: Lake trout Salvelinus namaycush in the Laurentian Great Lakes suffer from thiamine deficiency as a result of adult lake trout consuming prey containing thiaminase, a thiamine-degrading enzyme. Sufficiently low egg thiamine concentrations result in direct mortality of or sublethal effects on newly hatched lake trout fry. To determine the prevalence...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:: Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.
Abstract:: Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...

The effects of semi-chronic thermal stress on physiological indicators in steelhead Oncorhynchus mykiss

Creator:: Kammerer, Brittany D. and Heppell, Scott A.
Abstract:: The physiological response of juvenile steelhead (Oncorhynchus mykiss) to prolonged heat stress was examined by exposing replicated groups of fish to 25 consecutive days at 15°C, 23°C, and 25°C followed by a 55 day recovery period at 15°C. We found that at temperatures ≥25°C, steelhead consumed significantly less food per...

eDNA as a tool for identifying freshwater species in sustainable forestry: A critical review and potential future applications

Creator:: Coble, Ashley A., Flinders, Camille A., Homyack, Jessica A., Penaluna, Brooke E., Cronn, Richard C., and Weitemier, Kevin
Abstract:: Environmental DNA (eDNA) is an emerging biological monitoring tool that can aid in assessing the effects of forestry and forest manufacturing activities on biota. Monitoring taxa across broad spatial and temporal scales is necessary to ensure forest management and forest manufacturing activities meet their environmental goals of maintaining biodiversity. Our...

Host Identity Matters in the Amphibian-Batrachochytrium dendrobatidis System: Fine-Scale Patterns of Variation in Responses to a Multi-Host Pathogen

Creator:: Gervasi, Stephanie, Gondhalekar, Carmen, Olson, Deanna H., and Blaustein, Andrew R.
Abstract:: Species composition within ecological assemblages can drive disease dynamics including pathogen invasion, spread, and persistence. In multi-host pathogen systems, interspecific variation in responses to infection creates important context dependency when predicting the outcome of disease. Here, we examine the responses of three sympatric host species to a single fungal pathogen,...

Non-wadeable river bioassessment: spatial variation of benthic diatom assemblages in Pacific Northwest rivers, USA

Creator:: Pan, Yangdong, Hughes, Robert M., Herlihy, Alan T., and Kaufmann, Philip R.
Abstract:: Current bioassessment efforts are focused on small wadeable streams, at least partly because assessing ecological conditions in non-wadeable large rivers poses many additional challenges. In this study, we sampled 20 sites in each of seven large rivers in the Pacific Northwest, USA, to characterize variation of benthic diatom assemblages among...

Proximity to multiple foraging habitats enhances seabirds’ resilience to local food shortages

Creator:: Paredes, Rosana, Harding, Ann M. A., Irons, David B., Roby, Daniel D., Suryan, Robert M., Orben, Rachael A., Renner, Heather, Young, Rebecca, and Kitaysky, Alexander
Abstract:: As central-place foragers, seabirds from colonies located close to multiple and/or productive marine habitats might experience increased foraging opportunities and enhanced resilience to food shortages. We tested whether this hypothesis might explain divergent trends in 3 populations of black-legged kittiwakes Rissa tridactyla, a surface-feeding piscivore, in the eastern Bering Sea....
