Dispersal Behavior in African Buffalo (Syncerus caffer) : Tradeoffs Between Nutritional Resources and Disease Exposure

Creator:: Spaan, Robert Steven
Abstract:: Dispersal facilitates population health and maintains resilience in species via gene flow. Adult dispersal occurs in some species, is often facultative, and is poorly understood, but has important management implications, particularly with respect to disease spread. Although the role of adult dispersal in spreading disease has been documented, the potential...

Distribution and characteristics of an isolated population of coastal cutthroat trout (Oncorhynchus clarki) in streams of Triangle Lake Basin, Oregon

Creator:: Hurley, Steven M.
Abstract:: This research focused on features of a genetically isolated population of cutthroat trout (Oncorhynchus clarki) in the Triangle Lake basin of coastal Oregon. A falls at the outlet of Triangle Lake has blocked upstream migration of trout and anadromous salmonids into the basin. Cutthroat trout were found throughout the six...

Towards an Integrated Decision Tool for Managing Wildlife with Visitor Restrictions in Glacier Bay National Park

Creator:: Whitlock, Steven L.
Abstract:: The National Park Service has a dual mission of providing public access to exceptional natural resources, but in a manner such that these resources are left “unimpaired for the enjoyment of future generations.” Human activities in parks undoubtedly affect wildlife, but the degree to which such activities cause impairment is...

Seasonal movement patterns and habitat use of westslope cutthroat trout in two headwater tributary streams of the John Day River

Creator:: Starcevich, Steven J.
Abstract:: Radiotelemetry was used to study the seasonal movements and habitat use of adult westslope cutthroat trout Oncorhynchus clarki lewisi in Roberts Creek and Rail Creek, headwater tributaries of the John Day River, Oregon, from September 2000 to December 2001. The objectives were to (1) describe adult cutthroat trout life history...

Recruitment variability in black rockfish (Sebastes melanops): effects of maternal age on offspring quality

Creator:: Chapman, Colin G.
Abstract:: Black rockfish (Sebastes melanops) is an important marine recreational species throughout the Pacific Northwest. Recent catch data indicate a trend of age-truncation in the black rockfish population off the Oregon coast, with older females rapidly disappearing from the population. In populations with broad age distributions, older fish may contribute disproportionately...

Rearing conditions and their effects on growth, food conversion, and survival of English sole (Parophrys vetulus Girard)

Creator:: Williams, Steven Frank
Abstract:: This study consisted of determining some of the conditions for culture of young English sole (Parophrys vetulus Girard) in the laboratory. Rearing of the larvae to the juvenile stage was attempted unsuccessfully; techniques used and problems encountered during culture are discussed. Growth of juveniles was studied at combinations of temperatures...

Influence of channel constraint on primary production, preiphyton biomass, and macroinvertebrate biomass in streams of the Oregon Coast Range

Creator:: Zucker, Steven J.
Abstract:: Differences in primary production and periphyton and macroinvertebrate biomass between pairs of constrained (valley floor width of less than twice the active channel width) and unconstrained reaches were investigated in Elk River and four tributaries in southwest Oregon. In August 1991, macroinvertebrates were sampled from individual cobbles, and rocks were...

The heritability of resistance to gas bubble disease of Columbia River fall Chinook salmon, (Oncorhynchus tshawytscha)

Creator:: Cramer, Steven P.
Abstract:: A nested mating experiment in which 20 males were each mated to four different females was used to obtain an estimate of the heritability of resistance to death from gas bubble disease in Columbia River fall chinook salmon (Oncorhynchus tshawytscha). Heritability estimates ranged from 0. 037 to 0. 038. Bioassays...
