Couch's spadefoot toads (Scaphiopus couchii) breed in ponds of uncertain duration. In natural ponds, larvae exhibit considerable variation in growth, size at metamorphosis, and development time. Phenotypic differences in development time may dramatically affect survivorship in these ponds. A quantitative-genetic analysis of larval traits was undertaken to determine the potential evolutionary relevance of phenotypic variation observed in the field. Additive genetic variance was detected for… CONTINUE READING
