Abstract: | This paper summarises the effects of kerangas forest fragmentation on the non-volant small mammal community resident in the fragments based on a long term study conducted in Brunei Darussalam. These effects are shown as eight responses—a significant reduction in the species richness and diversity in relation to size of fragments, the disappearance of species with large home ranges and specific habitat requirements, invasion of generalists/opportunists into the fragments from degraded habitats, absence of predators, a possible reduction in the activity space of generalists in fragments, erosion in the trophic structure of the small mammal community, changes in the small mammal abundance in relation to fragment size and dominance of one species over other co-occurring species in an isolated fragment. These responses are briefly explained and their significance discussed. |
