Abstract
Data on population structure in toads, chiefly Bufo americanus, were gathered in northeastern Oklahoma in the spring of 1941. In the area studied, B. americanus [male][male] greatly outnumbered [female][female] in the breeding ponds (6:1 considering all breeding aggregations where both [male] and [female] toads were present). Mixed aggregations of B. americanus and B. woodhousii occur. The avg. size of 15 breeding aggregations of B. americanus was found to be 19.3 toads (16.6 [male][male] and 2.6 [female][female]). The [male] chorus daily loses and gains members. [male] toads that do not find mates may continue calling in the same pond or may migrate to another pond and call there.This publication has 1 reference indexed in Scilit:
