Abstract
Frogs breeding when environmental temps. are low deposit their eggs in a submerged compact jelly mass. The eggs in such a mass die of asphyxiation at temps. of pond water when the summer-breeding frogs spawn. Summer-breeding frogs lay their eggs in a surface film.This publication has 1 reference indexed in Scilit:
