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...

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...

Habitat selection behavior in three species of anuran larvae : environmental cues, ontogeny, and adaptive significance

Creator:: O'Hara, Richard K.
Abstract:: Habitat selection behavior was investigated as a proximate mechanism influencing spatial distributions of three species of anuran larvae. Rana cascadae, Hyla regilla, and Bufo boreas overlap in distribution in lakes and ponds of the Cascade Mts. and were chosen to provide a comparative basis for analyzing habitat selection behavior. Major...

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...
