Resumen

The aim of this study was to assessthe effect of larval density on larval development in these two species through an experimental study to investigatethe effect of larval density, during larval development, on developmental stages, size of larvae and size of newly metamorphosed juveniles and, if either of the species show inhibition, explore whether it is reversible.
