Characterizing neutral and adaptive genomic differentiation in a changing climate: The most northerly freshwater fish as a model

Creator:: O'Malley, Kathleen G., Vaux, Felix, and Black, Andrew N.
Abstract:: Arctic freshwater ecosystems have been profoundly affected by climate change. Given that the Arctic charr (Salvelinus alpinus) is often the only fish species inhabiting these ecosystems, it represents a valuable model for studying the impacts of climate change on species life‐history diversity and adaptability. Using a genotyping‐by‐se‐ quencing approach, we...

Sex matters: Otolith shape and genomic variation in deacon rockfish (Sebastes diaconus)

Creator:: Vaux, Felix, Rasmuson, Leif K., Kautzi, Lisa A., Rankin, Polly S., Blume, Matthew T. O., Lawrence, Kelly A., Bohn, Sandra, and O'Malley, Kathleen G.
Abstract:: Little is known about intraspecific variation within the deacon rockfish (Sebastes di‐ aconus), a recently described species found in the northeast Pacific Ocean. We in‐ vestigated population structure among fish sampled from two nearshore reefs (Siletz Reef and Seal Rock) and one offshore site (Stonewall Bank) within a <50‐km2 area...

A realignment of marine biogeographic provinces with particular reference to fish distributions

Creator:: Briggs, John C. and Bowen, Brian W.
Abstract:: Marine provinces, founded on contrasting floras or faunas, have been recognized for more than 150 years but were not consistently defined by endemism until 1974. At that time, provinces were based on at least a 10% endemism and nested within biogeographic regions that covered large geographic areas with contrasting biotic...

Relationship Between Wildfire, Salvage Logging, and Occupancy of Nesting Territories by Northern Spotted Owls

Creator:: Clark, Darren A., Anthony, Robert G., and Andrews, Lawrence S.
Abstract:: The northern spotted owl (Strix occidentalis caurina) is one of the most intensively studied raptors in the world; however, little is known about the impacts of wildfire on the subspecies and how they use recently burned areas. Three large-scale wildfires in southwest Oregon provided an opportunity to investigate the short-term...

Colony Connectivity of Pacific Coast Double-Crested Cormorants Based on Post-Breeding Dispersal From the Region’s Largest Colony

Creator:: Courtot, Karen N., Roby, Daniel D., Adkins, Jessica Y., Lyons, Donald E., King, D. Tommy, and Larsen, R. Scott
Abstract:: To reduce conflicts with fish resources, other colonial waterbirds, and damage to habitats, double-crested cormorants (Phalacrocorax auritus) are currently controlled (lethally and non-lethally) throughout much of their range. Concerns are growing over the Pacific Coast's largest double-crested cormorant colony at East Sand Island (ESI), Oregon near the mouth of the...

Statistical analysis on otolith data of anadromous fishes

Creator:: Gao, Yongwen, Conrad, Robert, Bean, David, and Noakes, David L. G.
Abstract:: Stable oxygen and carbon isotope δ[superscript 18]O and δ[superscript 13]C analyses of otoliths are becoming increasingly common in fisheries science and management. However, little is known about the statistical properties of isotopic data and few attempts have been made to explore appropriate statistical methods that could be used for otolith...

Internal helminth parasites of the lesser prairie-chicken Tympanuchus pallidicinctus in southwestern Kansas: incidence, burden, and effects

Creator:: Robel, Robert J., Walker, Thomas L. Jr, Hagen, Christian A., Ridley, Robert K., Kemp, Kenneth E., and Applegate, Roger D.
Abstract:: We conducted a 3-year study of helminth parasites to assess their effect on the lesser prairie-chicken Tympanuchus pallidicinctus. Helminth parasites were found in most of the examined wild prairie chicken carcasses: 95% had eye worm Oxyspirura petrowi, 92% had stomach worm Tetrameres sp., and 59% had caecal worm Subulura sp....

Habitat Selection by Greater Sage-Grouse During Winter in Southeastern Oregon

Creator:: Hagen, Christian A., Willis, Mitchell J., Glenn, Elizabeth M., and Anthony, Robert G.
Abstract:: The distribution and geographic range of Greater Sage-Grouse (Centrocercus urophasianus) have been reduced by 56% since European settlement. Although loss and fragmentation of sagebrush (Artemisia spp.) habitats have been cited as the primary causes for the decline of the species, degradation of existing habitat also has been considered an important...

Bird community responses to cattle stocking rates in a Pacific Northwest bunchgrass prairie

Creator:: Johnson, Tracey N., Kennedy, Patricia L., DelCurto, Tim, and Taylor, Robert V.
Abstract:: In 2006–2010, effects of four different cattle stocking rates (0, 14.4, 28.8, and 43.2 animal unit months) were compared, representing 0%, 20%, 32%, and 46% utilization of vegetation by domestic livestock, on vegetation structure (as indexed by visual obstruction), and songbird population and apparent nest density, community composition, and diversity...
