Response of avian communities to herbicide-induced vegetation changes, western Oregon

Creator:: Morrison, Michael L.
Abstract:: The relationships between avian community structure and herbicide modification of vegetation were analyzed on early-growth clearcuts in western Oregon that had received phenoxy herbicide treatment 1 or 4 years previously. Only minor effects of herbicide treatment were evident 1-year after spraying, except for red adler (Alnus rubra), which still exhibited...

Population and behavioral responses of small mammals to silviculture and downed wood treatments in the Oregon Coast Range

Creator:: Waldien, David L.
Abstract:: Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...

Salmon Management in Southeast Alaska: An Examination of Multi-Dimensional Management

Creator:: Chrittenden, Whitney L.
Abstract:: Pacific salmon are culturally and economically important species to Southeast Alaska, where there is a history of large wild runs and supplemental production from hatchery programs. Salmon management in Alaska is divided amongst various governmental agencies. Non-governmental organizations also play a pivotal role in salmon management. To fulfill the requirements...

How Behavior, Physiology, and Ontogeny of Klamath Redband Trout Shape the Functionality of Habitats in a Landscape of Temperature Extremes

Creator:: Hahlbeck, Nicholas J.
Abstract:: Climate change is a global phenomenon, but natural selection occurs within landscapes. A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. For coldwater fishes, it is widely assumed that maximum...

Interrenal and metabolic responses to stress and their modifying factors in juvenile salmonid fishes

Creator:: Barton, Bruce Alexander
Abstract:: Genetic, ontogenetic, and environmental factors modified characteristic interrenal and glycemic responses to stress in juvenile salmonid fishes. During continuous confinement stress, plasma cortisol rose more quickly in chinook salmon, Oncorhynchus tshawytscha, acclimated to high rather than medium or low temperatures; hyperglycemia following either acute or chronic stress was also highest...

Implications of cougar prey selection and demography on population dynamics of elk in northeast Oregon

Creator:: Clark, Darren A.
Abstract:: Mule deer (Odocoileus hemionus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni; hereafter elk) populations in northeast Oregon have declined in the past 10 to 20 years. Concurrent with these declines, cougar (Puma concolor) populations have apparently increased, leading to speculation that predation by cougars may be responsible for declining...

The association and distribution of fish species in Nyanza Gulf, Lake Victoria, East Africa, 1975

Creator:: Wanjala, Benny
Abstract:: A trawling survey was conducted on Nyanza Gulf, Lake Victoria, East Africa during March-December 1975 to investigate association and distribution of the major fish species and to provide information for management of the fishery. A total of 139 sites was sampled and all fishes caught were counted, measured, and weighed....

Effects of a 4-inch suction dredge on benthic macroinvertebrates in southwestern Oregon

Creator:: Perez, Diana H.
Abstract:: Effects of 4-inch (10.16 cm) suction dredge mining on benthic macroinvertebrates in 3rd to 4th order streams were investigated in 1996 by evaluating four mining claim operations in Althouse Creek, Sucker Creek, and Taylor Creek in southwestern Oregon's Rogue River basin. The effects were site-specific. The study showed no significant...
