Orientation and navigation in the rough-skinned newt, Taricha granulosa

Creator:

Darrow, Thomas D.

Abstract:

In the field of herpetology, most studies of homing have been carried out with anurans and, to a lesser degree, reptiles. Studies of orientation and navigation in urodeles have been limited to a few brief notes and the extensive investigation of Taricha rivularis by Twitty (1959 and 1964). The rough-skinned...

Investigations on the toxin of Taricha granulosa

Creator:

Brodie, Edmund D.

Abstract:

There are essentially no publications dealing with the skin toxin of Taricha granulosa. This study has undertaken investigations with this toxin in an attempt to determine its potency and its effect on the newt's potential predators. Test solutions were made by macerating a known volume of newt skin in a...

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....

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...

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...

An analysis of vocalizations of the rufous-sided towhee Pipilo erythrophthalmus oregonus (Bell)

Creator:

Abstract:

The purpose of this study was to record on tape and to analyze the sonagrams of the complete repertoire of the vocalizations of the Rufous-sided Towhee, Pipilo erythrophthalmus oregonus. Meanings were assigned to a number of the calls. Sounds of nestlings, juveniles, and vocalizations connected with parental care were not...

A study of behavior in the deer mouse Peromyscus maniculatus rubidus Osgood during its 24-hour cycle of activity in a simulated natural habitat

Creator:

Laban, Cornelis

Abstract:

With a growing emphasis on details of behavior comes an increasing need for knowledge of natural behavior patterns. Studies on the life history of Peromyscus maniculatus have long been available in the literature. More recently, investigators have turned to analyzing the behavior of some of the subspecies of P.m. in...
