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...

Aggregational behavior in the boreal toad Bufo boreas boreas Baird and Girard

Creator:: Dorsch, Anthony James
Abstract:: The object of this study was to investigate the possibilities of tracing aggregational behavior among Bufo boreas boreas larvae with reference to tadpole development, and to attempt to determine what aggregational factors initiate and maintain this behavior. Additionally, an attempt was made to determine the significance of temperature as an...

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...
