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...

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...

The respiratory ecology of the rough-skinned newt Taricha granulosa (Skilton)

Creator:: Smith, John Martin
Abstract:: An investigation was undertaken to determine if respiratory changes might occur in conjunction with migrations of the rough-skinned newt, Taricha granulosa (Skilton) in and out of ponds in the Willamette Valley. A field study was carried on from December 1964 through October 1965 to investigate certain physical and chemical parameters...

Small mammal micro- and macrohabitat selection in streamside ecosystems

Creator:: Doyle, Arlene T.
Abstract:: During summer and fall of 1981 to 1983, mark-recapture was conducted in riparian and upland habitats within old-growth and mature forests in the Cascade Range of Oregon. Number of individuals and species richness were greater in riparian than upland habitat. For most species, the mean adult weights and the percentages...

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...

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 dietary and morphometric analysis of sceloporine (Iguanidae) lizard populations

Creator:: White, Robert Lewis, II
Abstract:: Analyses of sympatric and allopatric populations of Sceloporus occidentalis and S. graciosus from central Oregon indicate a high degree of similarity in diet. Relative abundance, the equivalent number of equally common taxa (E), and the probability of similarity (SIMI) were used in the analyses. Shifts in diet between populations of...

The function of orange breeding coloration in the social behavior of the long-nosed leopard lizard (Gambelia wislizenii)

Creator:: Moore, Edith
Abstract:: The role of orange coloration in the breeding behavior of Gambelia wislizenii was examined in the Alvord Basin of southeast Oregon. Behavioral observations of free ranging lizards supplemented field experiments where I manipulated the sex and color of lizards encountered by resident female G. wislizenii before and after they acquired...
