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...

Bottom-up Drivers of Primary Producers and Predator Populations in Oregon Streams

Creator:: Kaylor, Matthew J.
Abstract:: Humans have drastically altered the physical habitat and food web structure of stream ecosystems. Two major impacts humans have had on Pacific Northwest streams are modification of streamside forests (as a result of agriculture, land development, and timber harvest), and declines in the return of wild anadromous salmon to headwater...

Status and habitat use of Columbian white-tailed deer in Douglas County, Oregon

Creator:: Smith, Winston Paul
Abstract:: A study conducted May 1978-December 1980 determined that the present geographic range of Columbian white-tailed deer, Odocoileus virginianus leucurus, (CWTD) in Douglas County, Oregon encompassed 1199km2. The area was predominately a Quercus woodland community, typical of the Interior Valley Zone of western Oregon. The CWTD distribution was not contiguous throughout...

Utilizing Fishermen Knowledge and Expertise: Keys to Success for Collaborative Fisheries Research

Creator:: Yochum, Noelle, Starr, Richard M., and Wendt, Dean E.
Abstract:: Collaborative fisheries research provides a mechanism for integrating the unique knowledge, experience, and skills of fishermen and scientists. It is a joint intellectual endeavor that begins with the inception of a project and continues until its final stages, with each group having mutual investment in-and ownership of-the project. Collaborative fisheries...

Responses of juvenile coho salmon and larval lamprey to instream habitat restoration in a Pacific Northwest stream

Creator:: Gonzalez, Rosalinda
Abstract:: Large wood has been utilized in many restoration projects to improve in-stream habitat in the Pacific Northwest for salmon. However, the benefits of this practice remain the subject of ongoing debate and evaluation of these projects has scarcely been done for non-salmonid species such as lamprey. In this study we...

Resource Selection and Space Use of Western Long-eared Myotis (Myotis evotis) in a Western Juniper (Juniperus occidentalis) Woodland of Central Oregon

Creator:: Anthony, Christopher R.
Abstract:: Identifying habitat and spatial requirements of wildlife species across multiple spatial scales is a challenging, yet crucial component of wildlife management. Habitat use of bats is particularly difficult to study, and managing habitat to conserve bats is especially challenging because bats are highly vagile organisms that exploit several different types...

Food and habitat partitioning in two groups of coexisting Accipiter

Creator:: Reynolds, Richard T.
Abstract:: Sharp-shinned Hawks (Accipiter striatus), and Cooper's Hawks (A. coo erii) in the conifer forests in northwestern Oregon and A. striatus, A. cooperii, and Goshawks (A. gentilis) in the conifer forests of eastern Oregon were syntopic during the nesting season. In this study density of nests, nest success, and utilization of...

Movement and space use by the green hermit (Phaethornis guy) in a fragmented landscape in Costa Rica

Creator:: Volpe, Noelia L.
Abstract:: Human activities have altered Earth’s ecosystems. Most biomes have experienced a 20-50% conversion to human use. Loss of habitat has obvious effects on the persistence of species. Fragmentation, however, may also negatively affect biodiversity for those species that exhibit behavioral responses to changes in habitat configuration. Such behavioral changes include...
