Movements and Settlement Site Selection of Pygmy Rabbits After Experimental Translocation

Creator:: Lawes, Timothy J., Anthony, Robert G., Robinson, W. Douglas, Forbes, James T., and Lorton, Glenn A.
Abstract:: We investigated the movements and selection of settlement sites of translocated pygmy rabbits (Brachylagus idahoensis) in southeastern Oregon from June to December 2008. We captured, radio tagged, and translocated 59 pygmy rabbits across big sagebrush (Artemisia tridentata ssp.) habitat with 3 categories of landscape fragmentation. We used radio telemetry to...

Surprises and Insights from Long-Term Aquatic Data Sets and Experiments

Creator:: Dodds, Walter K., Robinson, Christopher T., Gaiser, Evelyn E., Hansen, Gretchen J. A., Powell, Heather, Smith, Joseph M., Morse, Nathaniel B., Johnson, Sherri L., Gregory, Stanley V., Bell, Tisza, Kratz, Timothy K., and McDowell, William H.
Abstract:: Long-term research on freshwater ecosystems provides insights that can be difficult to obtain from other approaches. Widespread monitoring of ecologically relevant water-quality parameters spanning decades can facilitate important tests of ecological principles. Unique long-term data sets and analytical tools are increasingly available, allowing for powerful and synthetic analyses across sites....

The Influence of Wildfire and Invasive Vegetation on Mule Deer

Creator:: Schuyler, Elizabeth
Abstract:: The western United States has experienced large-scale degradation due to land use and land cover changes, invasion of annual grasses, and expansion of woody plants into grass and shrublands and the resultant altered fire regimes. These landscape-scale changes have coincided with declining mule deer (Odocoileus hemionus) populations, making habitat loss...

Patterns of color phase indicate spawn timing at a Nassau grouper Epinephelus striatus spawning aggregation

Creator:: Archer, Stephanie K., Heppell, Scott A., Semmens, Brice X., Pattengill-Semmens, Christy V., Bush, Phillippe G., Mccoy, Croy M., and Johnson, Bradley C.
Abstract:: Nassau grouper Epinephelus striatus are a large bodied, top level predator that is ecologically important throughout the Caribbean. Although typically solitary, Nassau grouper form large annual spawning aggregations at predictable times in specific locations. In 2003, The Cayman Islands Marine Conservation Board established protection for a newly rediscovered Nassau grouper...

Developmental rate: A unifying mechanism for sympatric divergence in postglacial fishes?

Creator:: Mcphee, Megan V., Noakes, David L. G., and Allendorf, Fred W.
Abstract:: Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms are often invoked to explain their origin. However, genetic recombination can constrain the ability of divergent selection to produce reproductive isolation in sympatry. Recombination breaks up favorable combinations of traits (”adaptive suites”) if individual traits are...

Acoustic monitoring reveals the times and tides of harbor porpoise (Phocoena phocoena) distribution off central Oregon, U.S.A.

Creator:: Holdman, Amanda K., Haxel, Joseph H., Klinck, Holger, and Torres, Leigh G.
Abstract:: Harbor porpoises (Phocoena phocoena) are commonly observed in Oregon's nearshore marine environment yet knowledge of their ecosystem use and behavior remains limited, generating concerns for potential impacts on this species from future coastal development. Passive acoustic monitoring was used to investigate spatial and temporal variations in the presence and foraging...

Temperature and the bioenergetics of Cichlasoma bimaculatum

Creator:: Sethi, Hari Singh
Abstract:: One means of evaluating the temperature requirements of an animal is to determine changes temperature causes in the uses and losses of energy and materials in the food the animal consumes. To develop energy budgets for cichlids (Cichlasoma bimaculatum) at different temperatures (20, 24, 28, 32 and 36 C) data...

The effects of concentration and particle size of suspended materials on growth and condition of the Pacific oyster (Crassostrea gigas)

Creator:: Wilson, William Joseph
Abstract:: The effects of exposure to suspended silt, kaolin and fuller's earth on growth and condition of Pacific oysters, 16 months of age, were studied. The exposure apparatus maintained a continuous flow of turbid water through chambers containing test oysters. Additional studies measured the filtration rates of oysters exposed to suspended...
