Abstract

This study examines amphibian reproductive modes in two habitat types- Frog Pond, Kubah National Park, within a lowland dipterocarp forest and peat swamp forest within UNIMAS campus, both in Sarawak, East Malaysia. The aim of the study is to describe and compare the diversity of amphibian reproductive modes in two distinct habitat types and to ascertain which reproductive modes are common in their respective habitat and their associated factors. Frog Pond, Kubah National Park and peat swamp forest within UNIMAS campus were chosen as study sites in this study. Data were collected from January 2014 to April 2014, with 34 individuals from 15 species. Sampling was conducted at night, when female frog were captured and their reproductive modes recorded. Female snout-vent length, egg diameters and clutch size are measured to the nearest 0.01 mm using vernier calliper. The most dominant amphibian reproductive modes at Frog Pond is Mode 23 (arboreal foam nest; feeding tadpoles in pond with three species) and followed by Mode 2 (egg and feeding tadpoles in lotic waters with three species) while at peat swamp forest is Mode 1 (egg and feeding tadpoles in lentic waters with 4 species). Hylarana luctuosa possibly shows the existence of parental care and Fejervarya limnocharis and Hylarana erythreae produced more eggs and exhibit generalized reproductive modes, Mode 1 (egg and feeding tadpoles in lentic waters).
