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...

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...

Geographic variation and systematics of the western Plethodon

Creator:: Brodie, Edmund D.
Abstract:: The western Plethodon include vandykei vandykei, v. idahoensis, larselli, dunni,vehiculum, stormi, elongatus, and an undescribed form referred to as the "unstriped" Plethodon. These salamanders have been placed into three species groups: the Vandykei group, the Vehiculum group, and the Elongatus group. Range maps are provided and geographic variation is discussed...

An investigation into the metamorphosis of Dicamptodon ensatus (Eschscholtz)

Creator:: Clothier, Glen Warren
Abstract:: The investigation was conducted from January 1965 to March 1966. An intensive effort was made to obtain large numbers of animals, as it is believed that unavailability of specimens has been the limiting factor in the amount of research concerning this species. Two hundred and sixty-nine animals were collected. They...
