Abstract:

Almost all discussions pertaining to the life-history of Rana pretiosa have been based on observations in British Columbia or the Pacific Northwest and except for the report of Tanner little has been made known for the eastern part of its range. Observations of the western spotted frog were made in the vicinity of Fishing Bridge in Yellowstone National Park during the summers of 1953-56, on the north shore of Yellowstone Lake near the outlet of the Yellowstone River at an elevation of about 7800 feet. This region has a mean annual temperature of 32.2° F. and a precipitation of 19.97 inches. The maximum temperature recorded over a 30-year period is at 94°; the minimum -56°. The bulk of these observations were made at or near four pools about 1.5 miles west of Fishing Bridge.
