Seasonal distribution and habitat selection by the redside shiner, Richardsonius balteatus, in a small Oregon stream

Creator:: Rodnick, Kenneth J.
Abstract:: Seasonal habitat availability, utilization, and selection by young of the year (< 25 mm) and adult (>25 mm) redside shiner, Richardsonius balteatus, were studied for 1 year in sections of Greasy Creek, Benton County, Oregon. Intensive stream mapping procedures and snorkling observations provided most of the quantitative measures for habitat...

Using DNA Metabarcoding to Study Interactions Between Native Bees and Plants: Technical Developments and Applications

Creator:: Arstingstall, Katherine A.
Abstract:: Pollination is an essential ecosystem service that sustains functioning ecosystems and aids in food production. In response to recent, widespread declines of managed and native bee populations, many land managers have shown interest in developing conservation and restoration plans for enhancing native bee habitat. However, there is a lack of...

Evolution and risk in conservation of Pacific salmon

Creator:: Currens, Kenneth P.
Abstract:: Identifying appropriate units for conservation requires knowledge of evolutionary patterns and risks of managing at different geographical and genetic scales. I examined genetic diversity at different geographical scales among 11,400 rainbow trout (Oncorhynchus mykiss) from 243 locations in 13 major river basins throughout much of their range and among coho...

Range-wide abundance and fluctuating asymmetry patterns of sagebrush-obligate passerine birds

Creator:: Krissman, Cortnie M.
Abstract:: North American sagebrush (Artemisia spp.) ecosystems are suffering from reductions in habitat extent and quality. Only about 50% of sagebrush remains from pre-settlement conditions, and much of the remaining habitat is fragmented or degraded by invasive species, fire suppression and overgrazing. Sagebrush-obligate species are experiencing population declines as a result...

A Dimensionless Invariant for Relative Size at Sex Change in Animals: Explanation and Implications

Creator:: Gardner, Andy, Allsop, David J., Charnov, Eric L., and West, Stuart A.
Abstract:: Recent comparative studies across sex-changing animals have found that the relative size and age at sex change are strikingly invariant. In particular, 91%–97% of the variation in size at sex change across species can be explained by the simple rule that individuals change sex when they reach 72% of their...

Population Genetics of American Pika (Ochotona princeps) : Investigating Gene Flow and Genetic Diversity Across Multiple, Complex Landscapes

Creator:: Castillo, Jessica A.
Abstract:: American pikas (Ochotona princeps) are considered an indicator species of climate change. Adaptations for cold climates and active winters make pikas particularly sensitive to increasing temperatures. This, combined with evidence that multiple historically occupied populations have been extirpated within the past century, contributed to American pikas becoming a focal species...

The effects of environmental stressors on cardiac gene expression and contractility in rainbow trout (Oncorhynchus mykiss)

Creator:: Momoda, Tracey S.
Abstract:: Rainbow trout (Oncorhynchus mykiss) experience a variety of stressors in their natural environment as well as in aquaculture that can have negative effects on their physiology. The effects of physiological stress and endocrine disruption have been well described in fish. However, there is a scarcity of information on the effects...

Ecology of harlequin ducks in Prince William Sound, Alaska, during summer

Creator:: Dzinbal, Kenneth A.
Abstract:: Harlequin ducks (Histrionicus histrionicus) were observed during the summers of 1979 and 1980 in Sawmill Bay, northeast Prince William Sound, Alaska. Harlequins were associated with a short, medium gradient, non-glacial stream (Stellar Creek) also used by salmon. Although harlequins nested along Stellar Creek, they apparently did not establish home ranges...

Patterns of genetic inheritance and variation through ontogeny for hatchery and wild stocks of Chinook salmon

Creator:: Hulett, Patrick L.
Abstract:: Although differences between selective pressures in hatcheries and streams have been theorized to cause genetic divergence between hatchery and wild salmonids, evidence of this is lacking. This study was initiated to document the presence or absence of genetic change in hatchery and wild stocks by characterizing genetic traits in fish...
