We studied geographic variation in allozymes (22 loci), mitochondrial cytochrome b gene sequences (575 bp), advertisement calls (pulse rate, call duration, and dominant frequency), and snout–vent length among populations of Hyla wrightorum and Hyla

Putative hybrid toads of the genus Bufo were collected in central Arizona and identified using allozymes, qualitative and qalsntitative morphological characters, and release call characteristics. Data suggest one hybrid resulted from mating between B
