Early maturing males in a partially migratory population of anadromous and resident rainbow trout Oncorhynchus mykiss: influences of individual condition and stream temperature

Creator:: McMillan, John R.
Abstract:: Alternative male phenotypes in salmonine fishes arise from individuals that mature as either larger and older anadromous marine-migrants or as smaller and younger freshwater residents. Variability in age and size of males at maturity is hypothesized to be preceded by early differences in growth in size and lipid storage. Water...

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...

Conserving avian diversity in agricultural systems : the role of isolated Oregon white oak legacy trees

Creator:: DeMars, Craig A.
Abstract:: Over one third of the earth’s land surface has been modified to some extent for agricultural purposes. The large global footprint of agriculture, combined with the knowledge that existing reserve networks are likely insufficient for long-term conservation of native biodiversity, has necessitated that agricultural systems contribute to conservation of native...

Habitat use by female greater sage grouse in relation to fire at Hart Mountain National Antelope Refuge, Oregon

Creator:: Byrne, Michael W.
Abstract:: The United States Fish and Wildlife Service currently uses fire as a management tool to improve Greater Sage Grouse (Centrocercus urophasianus Bonaparte) nesting and brood-rearing habitat at Hart Mountain National Antelope Refuge (HMNAR) in S.E. Oregon. Previous studies at HMNAR revealed use of burned areas by sage grouse throughout the...

Migratory behavior and passage of redband trout (Oncorhynchus mykiss) in the Donner und Blitzen River, Oregon

Creator:: Anderson, Matthew C.
Abstract:: Salmonids in arid high-elevation streams find themselves at the fringe of their tolerance range. Under the conditions they endure in such environments, long-distance migratory movements among widely dispersed habitats may be an important mechanism for some fish to persist, and even thrive. The Donner und Blitzen (Blitzen) River redband trout...

The effects of rotational grazing and prescribed burning on bobwhite populations in south Texas

Creator:: Wilson, Marcia H.
Abstract:: Short-term effects of 3 grazing systems and prescribed burning on bobwhite (Colinus virginianus) populations were investigated on the Welder Wildlife Refuge near Corpus Christi, Texas, during spring (April through June) and fall (September through October) of 1976 and 1977. Two rotational systems, high intensity-low frequency (HILF) and four-pasture, deferred-rotation (4PDR),...

Factors influencing within-watershed genetic variation of coastal cutthroat trout in Camp Creek, Oregon

Creator:: Wofford, John E.B.
Abstract:: Because human land use activities often result in increased fragmentation of headwater stream habitats, a better understanding of the effects of fragmentation on the genetic heterogeneity of stream salmonids is useful for effective management. We used eight microsatellites to examine the genetic structure of potamodromous coastal cutthroat trout (Oncorhynchus clarki...

Demography, home range, and habitat selection of northern spotted owls in the Ashland Watershed

Creator:: Schilling, Jason W.
Abstract:: Northern Spotted Owls (Strix occidentalis caurina) inhabit productive forests that historically supported frequent, large, variable-severity fires in the Klamath province of southwestern Oregon occur in complex. The potential for high-severity wildfire remains high throughout this region, so remaining spotted owl habitat is at risk. An adaptive management approach to fire...

Fall directions and breakage of riparian trees along streams in the Pacific Northwest

Creator:: Sobota, Daniel J.
Abstract:: In the Pacific Northwest, regulatory agencies have recently implemented management strategies for restoration and maintenance of wood recruitment to streams over time. This allochthonous organic material is a critical component in the geomorphic and biological structure of forested streams. Mathematical models are commonly used to evaluate long-term wood dynamics in...
