Investigation of the circadian rhythm of locomotion in the rough-skinned newt, Taricha granulosa

Creator:: Briggs, Jeffrey Lawrence
Abstract:: Over 56,000 hours of locomotor activity of Taricha granulosa were recorded using two types of low cylindrical plastic monitoring chambers. This species shows distinct rhythms of activity under normal day-night cycles, shortened day-night cycles, constant darkness (DD) and constant light (LL). The rough-skinned newt is day active and crepuscular. I...

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...

Thermal ecology of the garter snakes Thamnophis sirtalis concinnus (Hallowell) and Thamnophis ordinoides (Baird & Girard)

Creator:: Stewart, Glenn R.
Abstract:: In recent years, studies dealing with temperature regulation, temperature sensitivity, and physiological responses to temperature in lizards and other reptiles have increased tremendously. It is notable that snakes have been largely ignored in such studies. This no doubt is due to their less direct relationship to ancestral endotherms. However, problems...

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...

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...

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....
