Breeding habits, embryonic thermal requirements and embryonic and larval development of the Cascade frog, Rana cascadae Slater

Creator:: Sype, William E.
Abstract:: The breeding habits and embryonic thermal requirements of the Cascade frog of Oregon, Rana cascadae Slater, are described. The limits of temperature tolerance of the pre-feeding stages are from 6° to 27°C for embryos held at constant temperatures. However, for pre-feeding embryos exposed at different developmental stages for short durations...

A dietary and morphometric analysis of sceloporine (Iguanidae) lizard populations

Creator:: White, Robert Lewis, II
Abstract:: Analyses of sympatric and allopatric populations of Sceloporus occidentalis and S. graciosus from central Oregon indicate a high degree of similarity in diet. Relative abundance, the equivalent number of equally common taxa (E), and the probability of similarity (SIMI) were used in the analyses. Shifts in diet between populations of...

Morphological variations in populations of Lacerta from islands in the Adriatic Sea

Creator:: Clover, Robert C.
Abstract:: Phenetic relationships in insular populations of Lacerta sicula and L. melisellensis correspond to geologic ages of the islands in two regions of the Adriatic Sea. Populations of L. melisellensis on older islands are more similar to populations of L. sicula than are L. melisellensis from younger islands, and examination of...

Variations in salinity tolerance in the Pacific Treefrog, Hyla regilla, in Oregon

Creator:: Roberts, James Oliver
Abstract:: Eggs, larvae and adults of the four subspecies of Hy la regilla occurring in Oregon as given by Jameson, Mackey and Richmond (1966) were collected and subjected to salt stress in a series of graded seawaters. It was found that in all cases adults were more tolerant than larvae and...

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...

Investigation of the circadian rhythm of locomotion in the rough-skinned newt, Taricha granulosa

Creator:: Briggs, Jeffrey Lawrence
Abstract:: Over 56,000 hours of locomotor activity of Taricha granulosa were recorded using two types of low cylindrical plastic monitoring chambers. This species shows distinct rhythms of activity under normal day-night cycles, shortened day-night cycles, constant darkness (DD) and constant light (LL). The rough-skinned newt is day active and crepuscular. I...

A study of behavior in the deer mouse Peromyscus maniculatus rubidus Osgood during its 24-hour cycle of activity in a simulated natural habitat

Creator:: Laban, Cornelis
Abstract:: With a growing emphasis on details of behavior comes an increasing need for knowledge of natural behavior patterns. Studies on the life history of Peromyscus maniculatus have long been available in the literature. More recently, investigators have turned to analyzing the behavior of some of the subspecies of P.m. in...

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...
