Population ecology of the Columbian white-tailed deer

Creator:: Gavin, Thomas Alan
Abstract:: A population of Columbian white-tailed deer (CWTD) was studied on a refuge (790 ha) in southwestern Washington during 1972-77. Quality of habitat was considered good for these deer and total population size remained between 164-230 as determined by mark-recapture methods during November. Population size declined significantly between the winters of...

Studies on the molluscan and fish hosts of the "salmon poisoning" fluke, Nanophyetus salmincola (Chapin)

Creator:: Gebhardt, Gary Alan.
Abstract:: This study¹ was undertaken: (1) to obtain information on the distribution of the snail, Oxytrema silicula, in three coastal rivers in Oregon, and the seasonal incidence of infection in these snails and in snails from an inland stream, with the cercariae of the trematode, Nanophyetus salinincola; (2) to follow cercarial...

A simulation model of wood dynamics in Pacific Northwest streams

Creator:: Meleason, Mark Alan
Abstract:: Conceptually, the dynamics of wood in streams can be viewed in terms of input and in-channel processes. Input processes are associated with both the riparian (tree fall, bank cutting, windthrow) and upslope forests (mass failures). In-channel processes include log breakage, movement, and decomposition. A mechanistic view of these processes is...

Response of juvenile steelhead trout to an instream habitat rehabilitation project in Meadow Creek, Oregon

Creator:: Miller, Alan Christopher
Abstract:: Responses of juvenile steelhead trout to changes in stream habitat resulting from an instream habitat rehabilitation project in Meadow Creek, Oregon were measured from 1991 through 1992 and compared to pre-treatment data from 1987 through 1990. Sixty nine pool-forming, and 59 channel-stabilizing log structures were constructed by the U.S. Forest...

The reproductive biology of the mountain cottontail rabbit in Oregon

Creator:: Powers, Roger Alan
Abstract:: The reproductive characteristics of the mountain cottontail rabbit, Sylvilagus nuttalli (Bachman), were investigated from 269 specimens collected in central Oregon between 28 May 1968 and 28 August 1969. Male rabbits were in breeding condition between mid-February and 3 July 1969. Nearly 77% of the females bore four litters between 7...

Effects of ethyl mercury on some parameters of reproduction in ring-necked pheasants

Creator:: Christensen, Alan Gene
Abstract:: Prior to onset of the breeding season, a ration containing 18.4 mg/kg N-(Ethylmercuri)-p-toluene sulphonanilide was fed to 6 male and 16 female ring-necked pheasants (Phasianus colchicus). Birds receiving the mercury-treated ration were separated from the opposite sex. After receiving the mercury-treated ration for 0, 2, 4, 8, or 16 days,...

Patterns in Catch Per Unit Effort of Native Prey Fish and Alien Piscivorous Fish in 7 Pacific Northwest USA Rivers

Creator:: Hughes, Robert M. and Herlihy, Alan T.
Abstract:: OBJECTIVE. Hospital readmissions are a current target of initiatives to reduce healthcare costs. This study quantified the association between having a clinical culture positive for 1 of 3 prevalent hospital-associated organisms and time to hospital readmission. DESIGN. Retrospective cohort study. PATIENTS AND SETTING. Adults admitted to an academic, tertiary care...

Hydrologic and vegetation responses associated with restoration of wetlands in the Willamette Valley, Oregon

Creator:: Coleman, Gregory A.
Abstract:: I examined hydrological and plant community changes associated with the implementation of a restoration management plan in two riparian meadows located within an agricultural landscape of the central Willamette Valley, Oregon. I established exclosure fencing (a form of passive restoration) in one agricultural field and established fencing and plugged a...

Non-wadeable river bioassessment: spatial variation of benthic diatom assemblages in Pacific Northwest rivers, USA

Creator:: Pan, Yangdong, Hughes, Robert M., Herlihy, Alan T., and Kaufmann, Philip R.
Abstract:: Current bioassessment efforts are focused on small wadeable streams, at least partly because assessing ecological conditions in non-wadeable large rivers poses many additional challenges. In this study, we sampled 20 sites in each of seven large rivers in the Pacific Northwest, USA, to characterize variation of benthic diatom assemblages among...
