EMBRYONIC TEMPERATURE TOLERANCE AND RATE OF DEVELOPMENT IN RANA CATESBEIANA

JOHN A. MOORE 1

1 Queens College, Flushing, and the American Museum of Natural History, New York

A study of the embryonic temperature tolerance and rate of development of Rana catesbeiana has been made. The eggs develop normally between 15° C. and 32° C. and the time necessary to reach stage 20 at 20° C. is 134 hours. This species has the highest range of temperature tolerance and the slowest development of any of the five species of Rana common in the northeastern United States.

The significance of these results from an ecological point of view is discussed.

No difference in either rate of development or temperature tolerance of individuals from New York or Louisiana was found.

The relationship between the temperature coefficient (Q10 or b) of development and thermal adaptation is discussed. In frogs the value of b is greater in species adapted to high temperatures.
