Lambir Hills National Park

Feeding Time Preference and Distribution of Fishes and Shrimps in the ponds of Lambir Hills National Park

Trichoqaster sp.

This study was conducted on 30 and 31 July at Lambir Hills National Park (LHNP). In this study, we investigated feeding time preferences and distribution of fishes and shrimp between three pond in LHNP. Our study found a significant difference in number of shrimps (Carinidina sp.) in three ponds in LHNP (p=0.002) using fish traps (“Bubu botol”). However, there was no significant difference in the number of fish caught (Trichoqaster sp., Puntius sp. and Rasbora sp.) among ponds. We detected no feeding time preference from any of the species sampled.

Differential pollinator visitation to Melastoma malabathricum (Melastomataceae) under different ambient conditions


Study of Differential pollinator visitation to Melastoma malabathricum (Melastomataceae) under different ambient conditions was conducted at he Maliau Basin Conservation Area in Sabah, Malaysian Borneo on 21-24 August 2007. This study were investigated whether pollinator visitation is differentiated under different ambient conditions, which could imply the partitioning of limited resources by M. malabathricum flowers or the pollinator community. From the study, a total of 142 flowers in the sun and 322 in the shade and recorded 26 insect morphospecies visiting M. malabathricum flowers. Comparing the average number of all insect visitors on flowers, there is no significant difference between flowers in the shade and sun and only significant were ants excluded (p = 0.01845). These results suggest that ants may not discriminate between shaded and sunlit plants as much as insects capable of flight. However, bees also appear to have no preference for flowers in either the sun or the shade. Thus, the difference that we detected was likely due to other insects whose abundance was less than Hymenoptera but displayed stronger preferences.We conclude that M. malabathricum flowers attract different insect visitors under sun and under shade, but differences in abundance are only evident at certain scales.
