Ecology of Melomys burtoni, the Grasslnad Melomys (Rodentia : Muridae) at Cobourg Peninsula, N.T

Abstract

Reproduction, population dynamics, movements, and habitat preferences of Melomys burtoni were studied through a capture-mark-release program on Cobourg Peninsula. In 8714 trap-nights; 143 individuals were captured over 116 weeks. Breeding occurred throughout the year, with an increased incidence during the wet season. Juveniles entered the populations over an extended period, and recruitment was low. Resident animals tended to utilize discrete 'core-areas', and showed a clear preference for Dense Forest dominated by Acacia aulacocarpa and a dense understorey of Pandanus spiralis.
