Abstract
Estimations of survival rates of small mammal populations that occur on the island of New Guinea are crucial for conservation and management strategies. Here, we used mark-recapture data in programme MARK to estimate apparent survival and detection of two murid species in a tropical rainforest in Papua New Guinea. The most parsimonious model allowed survival and recapture probability to vary by species. Across the two species, Rattus verecundus generally had lower survival rates, but higher recapture probabilities, whereas Paramelomys platyops had higher survival rates but lower recapture probabilities. Since many small mammal species that occur in New Guinea are already listed under the IUCN red list for Threatened Species, similar studies can be replicated targeting the threatened species to provide information to wildlife managers for management and conservation decision.
