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...

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...

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....

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...

Morphological variations in populations of Lacerta from islands in the Adriatic Sea

Creator:

Clover, Robert C.

Abstract:

Phenetic relationships in insular populations of Lacerta sicula and L. melisellensis correspond to geologic ages of the islands in two regions of the Adriatic Sea. Populations of L. melisellensis on older islands are more similar to populations of L. sicula than are L. melisellensis from younger islands, and examination of...

Dissertation
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...

Dissertation
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...

Variations in salinity tolerance in the Pacific Treefrog, Hyla regilla, in Oregon

Creator:

Roberts, James Oliver

Abstract:

Eggs, larvae and adults of the four subspecies of Hy la regilla occurring in Oregon as given by Jameson, Mackey and Richmond (1966) were collected and subjected to salt stress in a series of graded seawaters. It was found that in all cases adults were more tolerant than larvae and...

Dissertation
Size variation and food habits of larval bullfrogs, Rana catesbeiana Shaw, in western Oregon

Creator:

Brown, Randall Errol

Abstract:

An investigation was made of the factors which cause differences in growth rates and transformation size of bullfrog tadpoles under natural conditions. Tadpoles and algal samples were collected from two.adjacent farm ponds of similar size during the eighteen months of the study. It was found that the tadpoles in one...

Morphological variation in the clouded salamander, Aneides ferreus (Cope) (Amphibia: Caudata: Plethodontidae)

Creator:

Beatty, Joseph J.

Abstract:

Multivariate morphometric analyses performed on ten populations of Aneides ferreus indicate that phenotypic expression in this species is exceedingly similar, but that on a fine scale there is considerable significant heterogeneity between most populations as well as between regional groups of populations. in terms of variation between California, Oregon, and...
