Circumpolar Diversity and Geographic Differentiation of mtDNA in the Critically Endangered Antarctic Blue Whale (Balaenoptera musculus intermedia)

Creator:: Sremba, Angela L., Hancock-Hanser, Brittany, Branch, Trevor A., LeDuc, Rick L., and Baker, C. Scott
Abstract:: The Antarctic blue whale (Balaenoptera musculus intermedia) was hunted to near extinction between 1904 and 1972, declining from an estimated initial abundance of more than 250,000 to fewer than 400. Here, we describe mtDNA control region diversity and geographic differentiation in the surviving population of the Antarctic blue whale, using...

Predation on an Upper Trophic Marine Predator, the Steller Sea Lion: Evaluating High Juvenile Mortality in a Density Dependent Conceptual Framework

Creator:: Horning, Markus and Mellish, Jo-Ann E.
Abstract:: The endangered western stock of the Steller sea lion (Eumetopias jubatus) - the largest of the eared seals - has declined by 80% from population levels encountered four decades ago. Current overall trends from the Gulf of Alaska to the Aleutian Islands appear neutral with strong regional heterogeneities. A published...

Catching the Right Wave: Evaluating Wave Energy Resources and Potential Compatibility with Existing Marine and Coastal Uses

Creator:: Kim, Choong-Ki, Toft, Jodie E., Papenfus, Michael, Verutes, Gregory, Guerry, Anne D., Ruckelshaus, Marry H., Arkema, Katie K., Guannel, Gregory, Wood, Spencer A., Bernhardt, Joanna R., Tallis, Heather, Plummer, Mark L., Halpern, Benjamin S., Pinsky, Malin L., Beck, Michael W., Chan, Francis, Chan, Kai M. A., Levin, Phil S., and Polasky, Stephen
Abstract:: Many hope that ocean waves will be a source for clean, safe, reliable and affordable energy, yet wave energy conversion facilities may affect marine ecosystems through a variety of mechanisms, including competition with other human uses. We developed a decision-support tool to assist siting wave energy facilities, which allows the...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:: Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.
Abstract:: Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

A Multi-Year Longitudinal Study of Water Quality Parameters in Four Salmon-Bearing and Recreational Streams on Mount Hood, Oregon

Creator:: Wasowski, Ronald, Alexander, David, Kolmes, Steven, Banet, Nathan, Card, Amy, Haines, Morgan, Kolmes, Elijah, Northcutt, Kelly, Roemer, Derek, and Webber, Sarah
Abstract:: Four streams-Clear Fork, Lost Creek, Camp Creek and Still Creek-in northwestern Oregon's Sandy River Basin were monitored for temperature, dissolved oxygen levels, and fecal bacterial concentrations in a multi-year analysis examining stream health for recreational users and anchor habitat for Pacific Salmon. Temperatures were recorded using micro -T temperature loggers...

Escaped farmed salmon and trout in Chile: incidence, impacts, and the need for an ecosystem view

Creator:: Sepúlveda, Maritza, Arismendi, Ivan, Soto, Doris, Jara, Fernando, and Farias, Francisca
Abstract:: The exponential growth of the salmonid farming industry during the last 3 decades has created conditions for massive escapes of these exotic species into natural environments in southern Chile. Here, we review and update information about salmonid escapes from 1993 to 2012 and examine their potential environmental, social, and economic...

Evaluating the Return in Ecosystem Services from Investment in Public Land Acquisitions

Creator:: Kovacs, Kent, Polasky, Stephen, Nelson, Erik, Keeler, Bonnie L., Pennington, Derric, Plantinga, Andrew J., and Taff, Steven J.
Abstract:: We evaluate the return on investment (ROI) from public land conservation in the state of Minnesota, USA. We use a spatially-explicit modeling tool, the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST), to estimate how changes in land use and land cover (LULC), including public land acquisitions for conservation, influence...

Quantification of Habitat and Community Relationships among Nearshore Temperate Fishes Through Analysis of Drop Camera Video

Creator:: Easton, Ryan R., Heppell, Selina S., and Hannah, Robert W.
Abstract:: Temperate nearshore reefs along the Pacific coast of North America are highly valuable to commercial and recreational fisheries yet comprise a small fraction of the seabed. Monitoring fisheries resources in this region is difficult; high-relief structural complexity and adverse sea conditions have led to a paucity of information on temperate...

Adaptive genetic markers discriminate migratory runs of Chinook salmon (Oncorhynchus tshawytscha) amid continued gene flow

Creator:: O'Malley, Kathleen G., Jacobson, Dave P., Kurth, Ryon, Dill, Allen J., and Banks, Michael A.
Abstract:: Neutral genetic markers are routinely used to define distinct units within species that warrant discrete management. Human-induced changes to gene flow however may reduce the power of such an approach. We tested the efficiency of adaptive versus neutral genetic markers in differentiating temporally divergent migratory runs of Chinook salmon (Oncorhynchus...

Development and Infectious Disease in Hosts with Complex Life Cycles

Creator:: Searle, Catherine L., Xie, Gisselle Yang, and Blaustein, Andrew R.
Abstract:: Metamorphosis is often characterized by profound changes in morphology and physiology that can affect the dynamics of species interactions. For example, the interaction between a pathogen and its host may differ depending on the life stage of the host or pathogen. One pathogen that infects hosts with complex life cycles...
