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...

Experimental hybridization between Rana pretiosa pretiosa Baird and Girard and Rana cascadae Slater

Creator:: Haertel, John David
Abstract:: Experimental crosses between Rana pretiosa pretiosa Baird and Girard and Rana cascadae Slater, resulted in viable hybrids. Reciprocal differences at the time of fertilization are indicated. A high level of success in producing viable hybrids can be obtained if Rana pretiosa pretiosa is the female of the parent species, The...

A comparative study of the chromosomes from five species of the genus Rana

Creator:: Haertel, John David
Abstract:: The karyotypes of five species of ranid frogs were determined from metaphase plates of bone marrow cells. The colchicine, hypotonic- citrate, blaze-dry technique was used to obtain the plates. Morphometric datawere obtained from the karyotypes and compared with other species of the genus Rana. Like most other members of the...

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...

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...
