Lesser prairie-chicken brood habitat in sand sagebrush: invertebrate biomass and vegetation

Creator:: Hagen, Christian A., Salter, G. Curran, Pitman, James C., Robel, Robert J., and Applegate, Roger D.
Abstract:: Invertebrates are an important food source for grouse chicks, especially within the first 2 weeks of life. Invertebrate abundance is highly patchy and dependent upon herbaceous cover and vegetation structure. We examined the relationship between invertebrate biomass (from sweepnet samples) and habitat structure at lesser prairie-chicken (Tympanuchus pallidicinctus) brood-use and...

Trichinella Surveillance in Black Bears (Ursus Americanus) from Oregon, USA

Creator:: Mortenson, J. A., Kent, M. L., Fowler, D. R., Chomel, B. B., and Immell, D. A.
Abstract:: We used serology and muscle digestion to test black bears (Ursus americanus) from western Oregon, USA, for Trichinella. Results indicate black bears in Oregon are not part of a sylvatic cycle for Trichinella, and risk of human exposure to Trichinella larvae from eating black bear meat from Oregon appears low.

A doubled down invasion of the northeast Pacific by the Asian mud shrimp, Upogebia major and its coevolved bopyrid isopod parasite, Orthione griffenis

Creator:: Chapman, John W., Li, Jingchun, McGowan, Michael F., Breitenstein, Ralph A., Appy, Ralph, Hieb, Kathryn A., Piotrowski, Christina N., and Elder, Leanne E.
Abstract:: Dramatic declines of the native northeast Pacific mud shrimp, Upogebia pugettensis over the last three decades have occurred in response to intense infestations by the Asian bopyrid isopod parasite, Orthione griffenis, that was introduced in the 1980s. We report herein the arrival of the Asian mud shrimp, Upogebia major, in...

Drone Up! Quantifying Whale Behavior From a New Perspective Improves Observational Capacity

Creator:: Lemos, Leila, Chandler, Todd E., Torres, Leigh G., and Nieukirk, Sharon L.
Abstract:: During traditional boat-based surveys of marine megafauna, behavioral observations are typically limited to records of animal surfacings obtained from a horizontal perspective. Achieving an aerial perspective has been restricted to brief helicopter or airplane based observations that are costly, noisy, and risky. The emergence of commercial small unmanned aerial systems...

Fishery-specific solutions to seabird bycatch in the U.S. West Coast sablefish fishery

Creator:: Good, Thomas P., Jannot, Jason E., Melvin, Edward F., Gladics, Amanda J., Suryan, Robert M., and Guy, Troy J.
Abstract:: Bird scaring lines (BSLs) protect longline fishing gear from seabird attacks, save bait, reduce incidental seabird mortality and are the most commonly prescribed seabird bycatch mitigation measure worldwide. We collaborated with fishermen to assess the efficacy of applying BSL regulations from the demersal longline sablefish fishery in Alaska to a...

Male Greater Sage-Grouse Detectability on Leks

Creator:: Fremgen, Aleshia L.
Abstract:: It is unlikely all male sage-grouse are detected during lek counts, which could complicate the use of lek counts as an index to population abundance. Understanding factors that influence detection probabilities will allow managers to more accurately estimate the number of males present on leks. We fitted 410 males with...

Relationship Between Wildfire, Salvage Logging, and Occupancy of Nesting Territories by Northern Spotted Owls

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate the short-term...

Do gray whales count calories? Comparing energetic values of gray whale prey across two different feeding grounds in the eastern North Pacific

Creator:: Hildebrand, Lisa, Bernard, Kim S., and Torres, Leigh G.
Abstract:: Predators must consume enough prey to support costly events, such as reproduction. Meeting high energetic requirements is particularly challenging for migrating baleen whales as their feeding seasons are typically restricted to a limited temporal window and marine prey are notoriously patchy. We assessed the energetic value of the six most...

Intra‐ and inter‐annual variation in gray whale body condition on a foraging ground

Creator:: Soledade Lemos, Leila, Burnett, Jonathan D., Chandler, Todd E., Sumich, James L., and Torres, Leigh G.
Abstract:: Baleen whales store energy gained on foraging grounds to support reproduction and other metabolic needs while fasting for long periods during migration. Whale body condition can be used to monitor foraging success, and thus better understand and anticipate individual‐ and population‐level trends in reproduction and survival. We assessed the body...
