Population trends in northern spotted owls: Associations with climate in the Pacific Northwest

Creator:: Glenn, Elizabeth M., Anthony, Robert G., and Forsman, Eric D.
Abstract:: We used reverse time capture-mark-recapture models to describe associations between rate of population change (λ) and climate for northern spotted owls (Strix occidentalis caurina) at six long-term study areas in Washington and Oregon, USA. Populations in three of six areas showed strong evidence of declining populations, while populations in two...

Genetic Connectivity of the Dungeness Crab (Cancer magister) Across Oceanographic Regimes

Creator:: Roegner, G. Curtis, Corbett, Kelly, Beacham, Terry D., Jacobson, Dave P., Jackson, Tyler M., and O'Malley, Kathleen G.
Abstract:: Limited approaches exist for studying population connectivity in widely dispersing marine benthic invertebrates. Genetic techniques can provide important insights toward identifying recruitment trajectories. Here, 10 microsatellite loci were used to examine connectivity among Oregon Dungeness crabs (Cancer magister, Dana, 1852) in the California Current System (CCS) (n = 801) as...

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...

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...

Experimental evidence that simplified forest structure interacts with snow cover to influence functional connectivity for Pacific martens

Creator:: Moriarty, Katie M., Epps, Clinton W., Betts, Matthew G., Hance, Dalton J., Bailey, J. D., and Zielinski, William J.
Abstract:: Context: Functional connectivity—the facilitation of individual movements among habitat patches—is essential for species’ persistence in fragmented landscapes. Evaluating functional connectivity is critical for predicting range shifts, developing conservation plans, and anticipating effects of disturbance, especially for species affected by climate change. Objectives: We examined whether simplifying forest structure influenced animal...

Effects of Low-Density Feeding on Elk-Fetus Contact Rates on Wyoming Feedgrounds

Creator:: Creech, Tyler G., Cross, Paul C., Scurlock, Brandon M., Maichak, Eric J., Rogerson, Jared D., Henningsen, John C., and Creel, Scott
Abstract:: High seroprevalance for Brucella abortus among elk on Wyoming feedgrounds suggests that supplemental feeding may influence parasite transmission and disease dynamics by altering the rate at which elk contact infectious materials in their environment. We used proximity loggers and video cameras to estimate rates of elk-to-fetus contact (the primary source...

A cost-efficient method to assess carbon stocks in tropical peat soil

Creator:: Warren, M. W., Kauffman, J. B., Murdiyarso, D., Anshari, G., Hergoualc'h, K., Kurnianto, S., Purbopuspito, J., Gusmayanti, E., Afifudin, M., Rahajoe, J., Alhamd, L., Limin, S., and Iswandi, A.
Abstract:: Estimation of belowground carbon stocks in tropical wetland forests requires funding for laboratory analyses and suitable facilities, which are often lacking in developing nations where most tropical wetlands are found. It is therefore beneficial to develop simple analytical tools to assist belowground carbon estimation where financial and technical limitations are...

Can catch share fisheries better track management targets?

Creator:: Melnychuk, Michael C., Essington, Timothy E., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., Pope, John G., and Smith, Anthony D. M.
Abstract:: Fisheries management based on catch shares – divisions of annual fleet-wide quotas among individuals or groups – has been strongly supported for their economic benefits, but biological consequences have not been rigorously quantified. We used a global meta-analysis of 345 stocks to assess whether fisheries under catch shares were more...

Catch shares, fisheries, and ecological stewardship: a comparative analysis of resource responses to a rights-based policy instrument

Creator:: Essington, Timothy E., Melnychuk, Michael C., Branch, Trevor A., Heppell, Selina S., Jensen, Olaf P., Link, Jason S., Martell, Steven J. D., Parma, Ana M., Pope, John G., and Smith, Anthony D. M.
Abstract:: Rights-based approaches are potentially promising tools to meet conservation objectives in natural resource management. Here, we evaluated how population status and fishery production respond to catch shares, a rights-based policy instrument in fisheries whereby participants are granted a right to harvest a fraction of the allowable catch. By analyzing time...

Macondo-1 well oil-derived polycyclic aromatic hydrocarbons in mesozooplankton from the northern Gulf of Mexico

Creator:: Mitra, Siddhartha, Kimmel, David G., Snyder, Jessica, Scalise, Kimberly, McGlaughon, Benjamin D., Roman, Michael R., Jahn, Ginger L., Pierson, James J., Brandt, Stephen B., Montoya, Joseph P., Rosenbauer, Robert J., Lorenson, Thomas D., Wong, Florence L., and Campbell, Pamela L.
Abstract:: Mesozooplankton (>200 μm) collected in August and September of 2010 from the northern Gulf of Mexico show evidence of exposure to polycyclic aromatic hydrocarbons (PAHs). Multivariate statistical analysis revealed that distributions of PAHs extracted from mesozooplankton were related to the oil released from the ruptured British Petroleum Macondo-1 (M-1) well...
