Conserving biological diversity not only commences by development of a catalogue of species and their geographical distribution but also the knowledge of species ecology.The aim of this study was to determine some ecological aspects of Beamys hindei on home range,burrowing and diet.Capture-mark-recapture was used for five nights consecutively per month from August 2010 to July 2012 in Zaraninge forest.Home range was analysed only for animals which were recaptured more than three times,twelve males and eleven females.Thirty two B.hindeis burrows were identified with their surrounding vegetation; twelve burrows were excavated and their structure sizes in length were measured.Soil samples were taken from each excavated burrow and its physical characteristics tested by the Buoyocous hydrometer method.Diet composition was determined in the stomachs of ten B.hindei.Male rats had larger range areas than females and burrow placements were associated with the presence of shrubs,herbs and grass and leaf litter in loamy sand soil.Large burrow structures were linked to the large body size of the animal,females had larger structures than males.Plant materials were the most abundant component of diet in the stomachs,others types were grains/seeds,fruits and invertebrates.Results suggest that lesser pouched rats collect food and store it in their burrow and thus spend more time in burrows.In our opinion,space use by B.hindei is influenced by vegetation,soil properties and diet,and are factors which may determine their distribution and conservation.
