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...

Reducing Impacts of Double-crested Cormorants to Natural Resources in Central New York: A Review of a Collaborative Research, Management, and Monitoring Program

Creator:: DeVault, Travis L., Chipman, Richard B., Barras, Scott C., Taylor, Jimmy D., Cranker, Carl P. III, Cranker, Elizabeth M., and Farquhar, James F.
Abstract:: Double-crested Cormorants (Phalacrocorax auritus) have used central New York waters for breeding and stopover habitats during migration since 1984. In response to public concern over Oneida Lake, the United States Department of Agriculture Wildlife Services and the New York State Department of Environmental Conservation initiated an integrated research, management and...

Greater Sage-Grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R., Robinson, W. Douglas, Petersen, Steven L., and Miller, Richard F.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) depend on sagebrush habitat for food and cover during winter, yet few sage-grouse winter ecology studies have been conducted. During January and February 2007, we monitored 22 radio-collared sage-grouse (7 females and 15 males) in central Oregon to characterize winter habitat use and movement patterns. We...

Body Size and Growth Rate Influence Emigration Timing of Oncorhynchus mykiss

Creator:: Tattam, Ian A., Ruzycki, James R., Li, Hiram W., and Giannico, Guillermo R.
Abstract:: Juvenile Oncorhynchus mykiss migrate extensively in freshwater during fall. We used individual tagging to study the spatial origin, influences, and outcomes of fall migration on fish that emigrated from summer rearing tributaries during fall (early-emigrants) and those that did not (late-emigrants) in the South Fork John Day River, Oregon. Fall...

Experimental brood enlargement differentially influences the magnitude of the corticosterone stress response in closely related, co-occurring songbirds

Creator:: Hardt, Braelei M., Ardia, Daniel R., Bashaw, Meredith J., and Rivers, James W.
Abstract:: 1. Rearing environments can shape offspring phenotype across taxa, yet little is known about how brood size influences hypothalamic-pituitary axis functioning, whether its expression trades off with growth, and the degree to which these -relationships vary between species. 2. We evaluated how brood size influenced nestling physiological (glucocorticoids) and somatic...

Evaluating the influence of land use, drought and reach isolation on the occurrence of freshwater mussel species in the lower Flint River Basin, Georgia (U.S.A.)

Creator:: Shea, Colin P., Peterson, James T., Conroy, Michael J., and Wisniewski, Jason M.
Abstract:: North American freshwater mussels have been subjected to multiple stressors in recent decades that have contributed to declines in the status and distribution of many species. However, considerable uncertainty exists regarding the relative influence of these factors on observed population declines. 2. We used an occupancy modelling approach to quantify...

Age-specific variation in apparent survival rates of male lesser-prairie-chickens

Creator:: Hagen, Christian A., Pitman, James C., Sandercock, Brett K., Robel, Robert J., and Applegate, Roger D.
Abstract:: We used mark-recapture methods to estimate age-specific apparent survival rates for male Lesser Prairie-Chickens (Tympanuchus pallidicinctus), a gamebird of conservation concern. A total of 311 male prairie-chickens (135 yearlings, 176 adults) were captured and banded during a 5-year study in southwest Kansas. Time-since-marking models were used to estimate apparent survival...

Gender identification and growth of juvenile lesser prairie-chickens

Creator:: Pitman, James C., Hagen, Christian A., Robel, Robert J., Loughlin, Thomas M., and Applegate, Roger D.
Abstract:: The ability to ascertain gender and age of juvenile grouse is essential for determining gender-specific population age structure and studying timing of reproductive events, respectively. We examined outer rectrix feathers from juvenile Lesser Prairie-Chickens (Tympanuchus pallidicinctus) captured at 30–40 and 50–60 days post-hatching. Blood samples were collected from most chicks...

The Western Pacific barred knifejaw, Oplegnathus fasciatus (Temminck & Schlegel, 1844) (Pisces: Oplegnathidae), arriving with tsunami debris on the Pacific coast of North America

Creator:: Chapman, John W., Ta, Nicholas, Miller, Jessica A., Carlton, James T., Miller-Morgan, Timothy, Calvanese, Thomas, Pleus, Allen E., and Burke, James
Abstract:: The Western Pacific Ocean barred knifejaw Oplegnathus fasciatus was found from 2013 to 2015 along the Pacific Coast of North America from Washington to California. The knifejaw was found in derelict vessels that had arrived on the Pacific Coast and that had been lost during the March 2011 Great Japan...

The influence of release strategy and migration history on capture rate of Oncorhynchus mykiss in a rotary screw trap

Creator:: Tattam, Ian A., Ruzycki, James R., Bayley, Peter B., Li, Hiram W., and Giannico, Guillermo R.
Abstract:: Rotary screw traps are used throughout the West Coast of North America to capture emigrating juvenile salmonids. Calibrating the capture efficiency of each trap is essential for valid estimates of fish passage. We released Passive Integrated Transponder (PIT) tagged Oncorhynchus mykiss upstream of a rotary screw trap in the South...
