238, 239, 241, 285-291. 1952: 20, 21, 47, 50-52, 55, Rana sired imssra Sycamore Camp Ground (cont.) May 1 In the stream tributary mentioned above, the water temperature at the edge was 15.4°C, in the middle 12.0°C. A frog sunning on a rock had a body temperature of 18.6°C; air temp 14.5°C, rock surface 21.4°C. In a pool containing many small frogs, a single transforming tadpole was found. Must have overwintered as a tadpole. How the rest of abundant young frogs transformed this spring? Adults were scarce. I took 2 male and a female here, and another female in Yule Rock Creek at Pine Mtn. Creek. Both females had bred. One appeared very thin, as if just bred, and still possessed abrasions on the chest.
