MANAGEMENT OF FRUIT BAT AND RAT POPULATIONS IN THE MALDIVE ISLANDS, INDIAN OCEAN
The introduced black rat (Rattus rattus) and the endemic giant fruit bat (Pteropus giganteus ariel) are serious depredators of coconuts and fruits, respectively, in the Maldives. Differences in reproductive rate between rats (high) and bats (low) must be considered in implementing control programs....
