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...

The early development of Ambystoma macrodatylum baird, with emphasis on the larval stages

Creator:: Hollenbeck, Robert Rudolph
Abstract:: The embryonic and larval stages of the long-toed salamander, Ambystoma macrodactylum are described from fertilization through the development of five toes on the posterior limbs. New stage numbers are employed in the description of the hind limb. The eggs used in the study were obtained by the injection of pituitary...

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...
