Nesting pair density and abundance of ferruginous hawks (Buteo regalis) and golden eagles (Aquila chrysaetos) from aerial surveys in Wyoming

Creator:: Olson, Lucretia E., Oakleaf, Robert J., Squires, John R., Wallace, Zachary P., and Kennedy, Patricia L.
Abstract:: Raptors that inhabit sagebrush steppe and grassland ecosystems in the western United States may be threatened by continued loss and modification of their habitat due to energy development, conversion to agriculture, and human encroachment. Actions to protect these species are hampered by a lack of reliable data on such basic...

Human-made structures, vegetation, and weather influence ferruginous hawk breeding performance

Creator:: Wallace, Zachary P., Kennedy, Patricia L., Squires, John R., Olson, Lucretia E., and Oakleaf, Robert J.
Abstract:: Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling at a scale functional for management. We used stratified random sampling and generalized linear mixed models to test hypotheses...

Re-Occupancy of Breeding Territories by Ferruginous Hawks in Wyoming: Relationships to Environmental and Anthropogenic Factors

Creator:: Wallace, Zachary P., Kennedy, Patricia L., Squires, John R., Oakleaf, Robert J., Olson, Lucretia E., and Dugger, Katie M.
Abstract:: Grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification. Because population performance of these species is also influenced by non-anthropogenic factors, it is important to incorporate all relevant ecological drivers into demographic models. We used design-based sampling and occupancy models to test relationships of environmental...

Parasites as indicators of English sole (Parophrys vetulus) nursery grounds

Creator:: Olson, Robert E. and Pratt, Ivan
Abstract:: Juvenile English sole, Parophrys vetulus utilize Yaquina Bay, Oregon, as a nursery during at least a portion of their first year of life, but the possibility of the existence of additional nursery grounds offshore has not previously been examined. During 1971, young-of the-year first appeared in Yaquina Bay in February,...

The Gill Pathogen Dermocystidium salmonis in Oregon Salmonids

Creator:: Olson, Robert E. and Holt, Richard A.
Abstract:: Intense infections of the gill pathogen Dermocystidium salmonis were associated with mortality of prespawning chinook salmon Oncorhynchus tshawytscha in several Oregon rivers in 1988. The occurrence of the pathogen in returning adult chinook salmon was monitored in several coastal Oregon stocks from 1989 to 1993. Although the prevalence of the...

Biologically Active Factors against the Monogenetic Trematode Gyrodactylus stellatus in the Serum and Mucus of Infected Juvenile English Soles

Creator:: Moore, Michelle M., Kaattari, Stephen L., and Olson, Robert E.
Abstract:: Length of survival of the monogenetic trematode Gyrodactylus stellatus in serum and mucus collected from English soles Pleuronectes vetulus at different stages of a laboratory epizootic suggests that both the mucus and serum may be involved in resistance to the parasite. In general, trematode survival was shorter in the serum...

Factors influencing density, distribution, and mesohabitat selection of juvenile wild salmonids and residual hatchery winter steelhead

Creator:: Brignon, William R., Olson, Douglas E., Schaller, Howard A., and Schreck, Carl B.
Abstract:: To best manage Eagle Creek National Fish Hatchery, negative interactions between hatchery salmonids and Endangered Species Act listed wild salmonids in the Eagle Creek Basin need to be minimized. Our objectives were: 1) to compare summer rearing densities in two similar streams, where one stream received a release of hatchery...

Plethodontid Salamander Distributions in Managed Forest Headwaters in Western Oregon, USA

Creator:: Olson, Deanna H. and Kluber, Matthew R.
Abstract:: We examined terrestrial amphibians in managed headwater forest stands in western Oregon from 1998 to 2009. We assessed: (1) temporal and spatial patterns of species capture rates, and movement patterns with distance from streams and forest management treatments of alternative riparian buffer widths and upland thinning; (2) species survival and...

Near-Term Effects of Repeated-Thinning with Riparian Buffers on Headwater Stream Vertebrates and Habitats in Oregon, USA

Creator:: Olson, Deanna H. and Burton, Julia I.
Abstract:: We examined the effects of a second-thinning harvest with alternative riparian buffer management approaches on headwater stream habitats and associated vertebrates in western Oregon, USA. Our analyses showed that stream reaches were generally distinguished primarily by average width and depth, along with the percentage of the dry reach length, and...
