Activity pattern and trapping behaviour of the Malaysian wood rat (Rattus tiomanicus Miller) in a cocoa-coconut plantation
Temporal activity patterns of the Malaysian wood rat, Rattus tiomanicus (Miller), in a cocoa-coconut plantation was monitored by their number of captures at two-hourly intervals. The rats are nocturnal and were found active between dusk and dawn. They exhibited three peak periods of activity during the night (1800 h - 2000 h, 2200 h - 2400 h, and 0200 h - 0400 h). Adults (body weight major or equal 90 g) were captured most. The trapping behaviour of the animal within a 24-hour period showed that out of 610 rats caught, 73 per cent of them were caught only once, 22 per cent twice, 4 per cent thrice and 1 per cent four times. Rainfall and bright moonlight seemed to affect their activities
