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...
