Abstract

The correlation between total rainfall and breeding parameters of White-Lipped frog, Rana labialis Schlegel was investigated at Junjong River, Kulim, Kedah, Malaysia for a period of 12 months. A number of breeding activities such as calling, amplexus, spawning and the presence of larvae were observed every week in each month. Observations showed that the breeding of these frog occurred throughout the year without any specific season and rain seems to be the major extrinsic factor that increased the breeding activities of the frog. Pearson correlation showed a positive relationship between total rainfall and a number of breeding parameters such as calling activities (r=0.85), amplexus (r=0.68) and number of egg clutches (r=0.82).
