Associations between forest fragmentation patterns and genetic structure in Pfrimer’s Parakeet (Pyrrhura pfrimeri), an endangered endemic to central Brazil’s dry forests

Creator:: Miller, M. P., Bianchi, C. A., Mullins, T. D., and Haig, S. M.
Abstract:: When habitat becomes fragmented, populations of species may become increasingly isolated. In the absence of habitat corridors, genetic structure may develop and populations risk reductions in genetic diversity from increased genetic drift and inbreeding. Deforestation of the Cerrado biome of Brazil, particularly of the dry forests within the Paran River...

Recovery potential of black rockfish, Sebastes melanops Girard, recompressed following barotrauma

Creator:: Pribyl, A. L., Schreck, C. B., Kent, M. L., Kelley, K. M., and Parker, S. J.
Abstract:: Overfished species of rockfish, Sebastes spp., from the Northeast Pacific experience high bycatch mortality because of ‘barotrauma’, a condition induced from the rapid change in pressure during capture. Field experiments show that it may be possible for rockfish to recover from barotrauma if quickly recompressed; however, no work has followed...

Multiple steroid and thyroid hormones detected in baleen from eight whale species

Creator:: Lysiak, Nadine S., Moore, Michael J., Hunt, Kathleen E., Robbins, Jooke, Seton, Rosemary E., Buck, C. Loren, and Torres, Leigh G.
Abstract:: Recent studies have demonstrated that some hormones are present in baleen powder from bowhead (Balaena mysticetus) and North Atlantic right (Eubalaena glacialis) whales. To test the potential generalizability of this technique for studies of stress and reproduction in large whales, we sought to determine whether all major classes of steroid...

Analysis of salmonid leukocytes purified by hypotonic lysis of erythrocytes

Creator:: Crippen, Tawni L., Bootland, Linda M., Leong, Jo-Ann C., Fitzpatrick, Martin S., Schreck, Carl B., and Vella, Anthony T.
Abstract:: A technique that uses hypotonic lysis of erythrocytes was optimized for the purification of leukocytes from the peripheral blood and anterior kidney (pronephros) of rainbow trout Oncorhynchus mykiss. Comparisons of initial blood dilution (1:2, 1:4, and 1:6) and the time of exposure to hypotonic conditions (10, 20, and 40 s)...

Population Structure and Phylogeography in Nassau Grouper (Epinephelus striatus), a Mass-Aggregating Marine Fish

Creator:: Jackson, Alexis M., Semmens, Brice X., de Mitcheson, Yvonne Sadovy, Nemeth, Richard S., Heppell, Scott A., Bush, Phillippe G., Aguilar-Perera, Alfonso, Claydon, John A. B., Calosso, Marta C., Sealey, Kathleen S., Schärer, Michelle T., and Bernardi, Giacomo
Abstract:: To address patterns of genetic connectivity in a mass-aggregating marine fish, we analyzed genetic variation in mitochondrial DNA (mtDNA), microsatellites, and single nucleotide polymorphisms (SNPs) for Nassau grouper (Epinephelus striatus). We expected Nassau grouper to exhibit genetic differentiation among its subpopulations due to its reproductive behavior and retentive oceanographic conditions...

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...

Female elk contacts are neither frequency nor density dependent

Creator:: Cross, P. C., Creech, Tyler G., Ebinger, M. R., Manlove, K., Irvine, K., Henningsen, J., Roberson, J., Scurlock, B. M., and Creel, S.
Abstract:: Identifying drivers of contact rates among individuals is critical to understanding disease dynamics and implementing targeted control measures. We studied the interaction patterns of 149 female elk (Cervus canadensis) distributed across five different regions of western Wyoming over three years, defining a contact as an approach within one body length...
