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...
