Abstract

Larval growth of Geocrinia victoriana and Pseudophryne semimarmorata was studied in tanks housing tadpoles of either species and mixed groups, providing the same density (individuals/water volume) in all containers. Tadpoles of P. semimarmorata were larger at hatching than G. victoriana, they reached metamorphic climax earlier and at larger sizes. In mixed groups, P. semimarmorata experienced relaxation of intraspecific competition; they metamorphosed at bigger sizes than controls kept only with conspecifics. In the presence of P. semimarmorata, G. victoriana showed slower growth initially; they metamorphosed later than the controls, but at similar sizes.
