The behavioral ecology of larval and neotonic northwestern salamanders (Ambystoma gracile)

Creator:: Taylor, James Thomas
Abstract:: In the summers of 1973, 1974 and 1975, I investigated population age structure and density, and behaviors relating to habitat selection, predator avoidance and intraspecific interaction in a population of northwestern salamanders in a lake in the Oregon Cascade Mountains. The study was carried out by skin- and scuba-diving at...

An analysis of a population of snowshoe hares, Lepus americanus washingtonii Baird, in western Oregon

Creator:: Black, Hugh C., 1941-
Abstract:: The ecology of a population of snowshoe hares, Lepus americanus washingtonii, was studied in western Oregon from 1960 to 1962. Objectives were to obtain information to control hares, which frequently cause damage to coniferous reproduction in the region, and to compare the life history of this little-studied subspecies with others....

A capture-recapture analysis of a mountain beaver population in western Oregon

Creator:: Lovejoy, Bill Pertl
Abstract:: This report summarizes the results of a field study of a population of the Pacific mountain beaver, Aplodontia rufa pacifica, from August 1965 through August 1967. The study site consisted of a 13. 5- acre grid on a logged over area in the Coast Range Mountains of Benton County, Oregon....

Geographic variation and systematics of the western Plethodon

Creator:: Brodie, Edmund D.
Abstract:: The western Plethodon include vandykei vandykei, v. idahoensis, larselli, dunni,vehiculum, stormi, elongatus, and an undescribed form referred to as the "unstriped" Plethodon. These salamanders have been placed into three species groups: the Vandykei group, the Vehiculum group, and the Elongatus group. Range maps are provided and geographic variation is discussed...

Aspects of the autecology of the plethodontid salamander, Aneides ferreus (Cope)

Creator:: McKenzie, Donald Samuel
Abstract:: Laboratory experiments and simulated field conditions were utilized to gain a better understanding of the ecology of the clouded salamander. Animals collected in western Oregon were utilized for studies in habitat selection, where it was shown that there was a significant pattern of selection of litter types (rock, bark, and...

Systematics of the salamander genus Dicamptodon strauch (Amphibia: Caudata: Ambystomatidae)

Creator:: Nussbaum, Ronald A.
Abstract:: Dicamptodon is the single, extant genus of the ambystomatid subfamily Dicamptodontinae. Two species, D. ensatus (Eschscholtz) and D. copei Nussbaum are recognized. D. ensatus is found in the forested, mountain regions of northwestern California and western Oregon, in the Willapa Hills and Cascade Mountains of Washington, in extreme southwestern British...

Geographic variation in Dunn's salamander Plethodon dunni Bishop (Amphibia:Caudata:Plethodontidae)

Creator:: Hanlin, Hugh Grady
Abstract:: Life history attributes and apparent distributional patterns suggest that Plethodon dunni exists as small, semi-isolated populations throughout its range. Isozyme and morphological variation in this species was examined to determine any possible geographic trends. Starch gel electrophoresis was utilized to examine genetic variation at 24 isozyme loci in 287 individuals...
