| Notes | Interesting observations are tucked away in this Master’s thesis. Consider this example of the habits of the rough-skinned newt, Taricha granulosa, which Graf calls by its older name, Triturus similans, “During late summer and early fall large masses or groups of Triturus have been observed to congregate at a common point in the water . . . The numbers observed have been from a dozen to fifty or sixty and even up to several hundred. July 16, 1938, such a mass group was observed in Beaver Creek between Waldport and Newport about a mile above the mouth of the creek. The water was perfectly clear and about three or four feet deep where about sixty Triturus were “swarming” in a quite compact mass in the middle of the stream about a foot above the bottom of the stream bed. All seemed to be crowding about a common point, yet there was nothing visible which might attract them.” Includes bw photographs of specimens and habitats. |
