Nested scales of spatial heterogeneity in juvenile walleye pollock Theragra chalcogramma in the southeastern Bering Sea

Creator:: Benoit-Bird, Kelly J., McIntosh, Neal E., and Heppell, Scott A.
Abstract:: We sought to characterize the distribution of juvenile walleye pollock Theragra chalcogramma in an area of intense predator-prey interactions and to describe habitat features that lead to their observed distributions. The distribution of juvenile walleye pollock around the Pribilof Islands in the southeastern Bering Sea in 2008 and 2009 was...

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...

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....

Addressing Challenges in the Application of Animal Movement Ecology to Aquatic Conservation and Management

Creator:: Ogburn, Matthew B., Mills Flemming, Joanna E., Harrison, Autumn-Lynn, Cooke, Steven J., Torres, Leigh G., and Whoriskey, Frederick G.
Abstract:: The dynamic nature of most environments forces many animals to move to meet their fundamental needs. This is especially true in aquatic environments where shifts in spatial ecology (which are a result of movements) are among the first adaptive responses of animals to changes in ecosystems. Changes in the movement...

Nighttime foraging by deep diving echolocating odontocetes off the Hawaiian islands of Kauai and Ni’ihau as determined by passive acoustic monitors

Creator:: Au, Whitlow W. L., Giorli, Giacomo, Chen, Jessica, Copeland, Adrienne, Lammers, Marc, Richlen, Michael, Jarvis, Susan, Morrissey, Ronald, Moretti, David, and Klinck, Holger
Abstract:: Remote autonomous ecological acoustic recorders (EARs) were deployed in deep waters at five locations around the island of Kauai and one in waters off Ni'ihau in the main Hawaiian island chain. The EARs were moored to the bottom at depths between 400 and 800 m. The data acquisition sampling rate...

Sex identification PCR–RFLP assay tested in eight species of Sebastes rockfish

Creator:: Vaux, Felix, Aycock, Hannah M., Bohn, Sandra, Rasmuson, Leif K., and O'Malley, Kathleen G.
Abstract:: The phenotypic identification of sex in Sebastes rockfish is difficult and often impractical from a management perspective, and the genetic basis of sex determination in the genus is currently uncertain. We tested a previously developed sex identifi- cation polymerase chain reaction restriction fragment length polymorphism (PCR–RFLP) assay in eight species...

A sense of scale : Foraging cetaceans’ use of scale-dependent multimodal sensory systems

Creator:: Torres, Leigh G.
Abstract:: Research on cetacean foraging ecology is central to our understanding of their spatial and behavioral ecology. Yet, functional mechanisms by which cetaceans detect prey across different scales remain unclear. Here, I postulate that cetaceans utilize a scale-dependent, multimodal sensory system to assess and increase prey encounters. I review the literature...

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...

A Comparison of Stipends, Health Insurance, and Tuition Remission Policies at Fisheries and Wildlife Graduate Programs throughout the United States

Creator:: Schultz, Luke D. and VanDeHey, Justin A.
Abstract:: Many factors should be considered before selecting a graduate program to attend. Graduate education can be expensive, so financial and health care benefits offered by a department or college should be considered when selecting a graduate program. A majority of fisheries graduate students recently surveyed believed that financial aspects should...

Elemental Markers in Elasmobranchs: Effects of Environmental History and Growth on Vertebral Chemistry

Creator:: Smith, Wade D., Miller, Jessica A., and Heppell, Selina S.
Abstract:: Differences in the chemical composition of calcified skeletal structures (e.g. shells, otoliths) have proven useful for reconstructing the environmental history of many marine species. However, the extent to which ambient environmental conditions can be inferred from the elemental signatures within the vertebrae of elasmobranchs (sharks, skates, rays) has not been...
