Abstract

Few studies have been done on natural mineral licks visitation on  bat fauna, particularly in Borneo and Southeast Asia in general. Little is known about the assemblage of bats using mineral licks and this study was done to determine assemblage structure of Palaeotropical bats at six established mineral licks in Deramakot and Tangkulap Forest Reserve, Sabah. The main findings of the present study revealed that Palaeotropical frugivorous bats were using mineral licks, observed through their behaviour of drinking from mineral licks, supported by their high species occurrences at mineral licks and higher concentration of water insoluble soil tracer elements, Al and Si detected in their faeces in comparison with non-visitor bats. The five species of bats Macroglos susminimus (n=3), Balionycteris maculata (n=2), Cynopterus brachyotis (n=1), Megaerops ecaudatus (n=2) and Penthetor lucasii n=(1) were observed drinking from mineral licks. Four species of frugivorous bats (M. minimus, B. maculata, C. brachyotis and P. lucasii)  frequently occurred at all six sites at mineral licks. In addition, there were higher enrichment Al and Si in M. minimus faeces (n=5) in comparison with non-visitor bats suggesting that frugivorous bats got those elements from ingestion of mineral lick muddy water.
