Comparing anuran performance and movement

Creator:: Bredeweg, Evan M.
Abstract:: Movement in an important component of an animal’s life cycle when it relies on both aquatic and terrestrial habitats. When multiple species overlap in the use of these habitats, they rely on other methods to reduce competition for shared resources. This dataset measured the jumping performance and movement behavior of...

Food selection and juvenile survival in Nuttall's cottontails in central Oregon

Creator:: Hundertmark, Kris Joseph
Abstract:: A population of Nuttall's cottontails (Sylvilagus nuttallii) in Deschutes County, Oregon, decreased fromm 166 individuals in August 1978 to 76 individuals in August 1979. Survival rates of four annual litter groups in 1978 were 0.74, 0.35, 0.72, and 0.93; survival rates for the same litter groups, respectively, in 1979 were...

A global assessment of freshwater fish introductions in Mediterranean-climate regions

Creator:: Marr, Sean M., Olden, Julian D., Leprieur, Fabien, Arismendi, Ivan, Caleta, Marko, Morgan, David L., Nocita, Annamaria, Sanda, Radek, Tarkan, A. Serhan, and Garcia-Berthou, Emili
Abstract:: Mediterranean-climate regions (med-regions) are global hotspots of endemism 40 facing mounting environmental threats associated with human-related activities, including the ecological impacts associated with non-native species introductions. We review freshwater fish introductions across med-regions to evaluate the influences of non-native fishes on the biogeography of taxonomic and functional diversity. Our synthesis...

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...

Local and regional stressors interact to drive a salinization-induced outbreak of predators on oyster reefs

Creator:: Kimbro, David L., White, J. Wilson, Tillotson, Hanna, Cox, Nikkie, Christopher, Megan, Stokes-Cawley, Owen, Yuan, Samantha, Pusack, Timothy J., and Stallings, Christopher D.
Abstract:: Predator outbreaks are predicted to increasingly decimate economically and ecologically important prey populations because global climate change and food-web modifications frequently facilitate predators and stress prey. Natural systems are organized hierarchically, with processes operating at multiple scales giving rise to patterns of biodiversity, so predicting and managing outbreaks requires a...

Patterns of loggerhead turtle ontogenetic shifts revealed through isotopic analysis of annual skeletal growth increments

Creator:: Ramirez, Matthew D., Avens, Larisa, Seminoff, Jeffrey A., Goshe, Lisa R., and Heppell, Selina S.
Abstract:: Ontogenetic changes in resource use often delimit transitions between life stages. Ecological and individual factors can cause variation in the timing and consistency of these transitions, ultimately affecting community and population dynamics through changes in growth and survival. Therefore, it is important to document and understand behavioral and life history...

Can humans coexist with fishes?

Creator:: Albins, Mark A., Evans, Allison, Ismail, Gladys, Neilsen, Brian, Pusack, Timothy, Schemmel, Eva, Smith, Wade, Stoike, Susanne, Li, Hiram W., and Noakes, David L. G.
Abstract:: Deciding which textbook to assign to students is often a very difficult decision. A textbook should offer more than just a synthesis of information, it should inspire curiosity, cause one to reflect, and provide a framework for making decisions. Most reviews reflect a single opinion, sometimes based on personal preferences....

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...
