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....
Resource Type:: Dissertation
Full Text:: Douglas -fir. Traps usually were set for three successive days at monthly intervals. Trapped hares

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...

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...

Breeding habits, embryonic thermal requirements and embryonic and larval development of the Cascade frog, Rana cascadae Slater

Creator:: Sype, William E.
Abstract:: The breeding habits and embryonic thermal requirements of the Cascade frog of Oregon, Rana cascadae Slater, are described. The limits of temperature tolerance of the pre-feeding stages are from 6° to 27°C for embryos held at constant temperatures. However, for pre-feeding embryos exposed at different developmental stages for short durations...

Full Text:: described. The limits of temperature tolerance of the pre-feeding stages are from 6° to 27°C for embryos

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...
Resource Type:: Dissertation
Full Text:: effects of size, temperature (10, ZO, 5°C), and feeding regime were noted. Young animals displayed the

The habitat requirements and ecological relationships of Microtus oregoni (Bachman), Microtus townsendii (Bachman), and Microtus montanus (Peale) in Benton County, Oregon

Creator:: Goertz, John William
Abstract:: The object of this research is to ascertain the habitat occupied by each of the three species of voles of the genus Microtus found living in Northern Benton County, Oregon.

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 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...
