dc.description.abstract"Sex recognition in the wood-frog, Rana sylvatica, is first accomplished after the embrace, the males retaining their grip on individuals having a certain girth and degree of firmness of body. 2. A chemical sense plays no part in sex recognition but the warning croak of an embraced male may shorten, and the normal movements of an embraced individual may increase the time period of the embrace. Other modifying factors are fatigue, degree of sexual ardor, and retreat of pair below surface of the water. 3. Males release females after egg laying for the same reason they release males which they happen to embrace. The body of both groups of individuals does not have the required girth or firmness to permit their continuing the embrace"--P. 16.en_US
