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...

Assessment of fecal steroid and thyroid hormone metabolites in eastern North Pacific gray whales

Creator:: Lemos, Leila S., Olsen, Amy, Smith, Angela, Chandler, Todd E., Larson, Shawn, Hunt, Kathleen, and Torres, Leigh G.
Abstract:: Baleen whale fecal samples have high potential for endocrine monitoring, which can be used as a non-invasive tool to identify the physiological response to disturbance events and describe population health and vital rates. In this study, we used commercial enzyme-linked immunosorbent assays to validate and quantify fecal steroid (progestins, androgens...

Timing of Population Fragmentation in a Vulnerable Minnow, the Umpqua Chub, and the Role of Nonnative Predators

Creator:: O’Malley, Kathleen G., Markle, Douglas F., and Ardren, William R.
Abstract:: We examined the distribution of Umpqua Chub Oregonichthys kalawatseti, an endemic, vulnerable minnow in western Oregon, and whether six ecological populations (based on distribution patterns) had sufficient genetic cohesion to be considered evolutionary populations. We also evaluated the influence of Holocene geological events and recent nonnative predator introductions on the...

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...

Factors affecting female space use in ten populations of prairie chickens

Creator:: Winder, Virginia L., Carrlson, Kaylan M., Gregory, Andrew J., Hagen, Christian A., Haukos, David A., Kesler, Dylan C., Larsson, Lena C., Matthews, Ty W., McNew, Lance B., Patten, Michael A., Pitman, Jim C., Powell, Larkin A., Smith, Jennifer A., Thompson, Tom, Wolfe, Donald H., and Sandercock, Brett K.
Abstract:: Conservation of wildlife depends on an understanding of the interactions between animal movements and key landscape factors. Habitat requirements of wide-ranging species often vary spatially, but quantitative assessment of variation among replicated studies at multiple sites is rare. We investigated patterns of space use for 10 populations of two closely...

Patterns in Catch Per Unit Effort of Native Prey Fish and Alien Piscivorous Fish in 7 Pacific Northwest USA Rivers

Creator:: Hughes, Robert M. and Herlihy, Alan T.
Abstract:: OBJECTIVE. Hospital readmissions are a current target of initiatives to reduce healthcare costs. This study quantified the association between having a clinical culture positive for 1 of 3 prevalent hospital-associated organisms and time to hospital readmission. DESIGN. Retrospective cohort study. PATIENTS AND SETTING. Adults admitted to an academic, tertiary care...

The response to forced decompression in six species of Pacific rockfish

Creator:: Pribyl, Alena L., Kent, Michael L., Parker, Steven J., and Schreck, Carl B.
Abstract:: Pacific rockfish experience high discard mortality when captured owing to a condition called barotrauma,which is caused by the change in pressure during capture. This condition appears to be species specific at the macroscopic level; however, little is known about the microscopic tissue-level effects of barotrauma. Determining whether tissue-level injuries are...

Columbia River salmonid outmigration : McNary Dam passage and enhanced smolt quality : completion report, April 1, 1985

Creator:: Schreck, Carl B. and Li, Hiram W.
Abstract:: We evaluated the effects of the McNary Dam transportation system on emigrating fall and spring chinook smolts using physiological indices of stress (e.g., plasma cortisol, hepatic glycogen, leucocrit, interrenal cell nuclear diameter) and performance tests (e.g., saltwater challenge, secondary stress challenge, disease resistance). We also conducted controlled experiments in a...

The idiosyncrasies of place: geographic variation in the climate–distribution relationships of the American pika

Creator:: Jeffress, Mackenzie R., Rodhouse, Thomas J., Ray, Chris, Wolff, Susan, and Epps, Clinton W.
Abstract:: Although climate acts as a fundamental constraint on the distribution of organisms, understanding how this relationship between climate and distribution varies over a species’ range is critical for addressing the potential impacts of accelerated climate change on biodiversity. Bioclimatic niche models provide compelling evidence that many species will experience range...
