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...

Status and habitat preference of California bighorn sheep on Sheldon National Wildlife Refuge, Nevada

Creator:: Hansen, Michael Charles
Abstract:: A herd of California bighorn sheep (Ovis canadensis californiana), re-introduced to the area of Hell Creek on the Sheldon National Wildlife Refuge in northwestern Nevada, was studied from 15 June 1978 to 20 August 1980. Major vegetation and physiographic types were delineated and described. Habitat preferences were determined from field...

A morphometric analysis of geographic variation within Sorex monticolus

Creator:: Alexander, Lois F.
Abstract:: Shrews previously recognized as Sorex monticolus were classified into two species (one with 14 subspecies, the other monotypic) on the basis of a morphometric analysis of 3610 individuals from throughout their range. Sorex m. neomexicanus has been recognized previously as a subspecies of Sorex monticolus but is recognized herein as...

Riparian bird communities in Portland, Oregon : habitat, urbanization, and spatial scale patterns

Creator:: Hennings, Lori A.
Abstract:: Urban ecosystems are characterized by human disturbance and changes in the amount, types, and spatial arrangement of wildlife habitat. The relative importance of habitat and human associated variables to urban birds is unknown. In 1999, I surveyed spring bird and plant communities along 54 perennial streams in the Portland, Oregon...

Effects of diet and crude oil ingestion on growth and biochemistry of captive-reared pigeon guillemots (Cepphus columba)

Creator:: Hovey, Andrew K.
Abstract:: The pigeon guillemot (Cepphus columba) population in Prince William Sound has failed to recover from declines that occurred both before and after the Exxon Valdez Oil Spill (EVOS). Post-spill studies of pigeon guillemot breeding biology have identified three potential factors limiting recovery: (1) predation on eggs and nestlings; (2) declines...

Breeding and foraging ecology of Caspian terns (Sterna caspia) in the mid-Columbia River : predation on juvenile salmonids and management implications

Creator:: Antolos, Michelle
Abstract:: I investigated Caspian terns (Sterna caspia) breeding at colonies on the Columbia Plateau (southeastern Washington and northeastern Oregon), with emphasis on the breeding and foraging ecology of Caspian terns nesting at colonies in the mid-Columbia River. I focused research at colonies where Caspian terns foraged on juvenile salmonids (Oncorhynchus spp.)...

Factors affecting colony size, reproductive success, and foraging patterns of double-crested cormorants nesting on East Sand Island in the Columbia River Estuary

Creator:: Anderson, Cynthia D.
Abstract:: The purpose of this study was to investigate the primary factors affecting colony size, reproductive success, and foraging patterns of Double-crested Cormorants (Phalacrocorax auritus albociliatus) nesting at East Sand Island in the Columbia River estuary, the largest colony of this species on the Pacific Coast of North America. This colony...
