Abstract


Movements of animals play a major role in the ecology of species, as it influence the dynamics of the populations and can connect populations and communities. Here we documented an exceptional long distance daily movement of a small marsupial, Gracilinanus microtarsus, in a two-year capture-recapture study at the Atlantic forest in southeastern Brazil. A sub-adult male moved between grids, a distance of 1.6 km, within 24 hours. This distance is higher than usual distances recorded for this and other small didelphid marsupials and reveals unknown abilities of short-time long distance dispersal. This occasional and exceptional observation brings attention to unknown abilities of space-use of Neotropical marsupials and encourages future studies which could be valuable for conservation of species.
