Small monkey groups may win territorial disputes against larger groups because some members of the larger, invading groups avoid aggressive encounters. In a new report published in Proceedings of the National Academy of Sciences, Margaret Crofoot and Ian Gilby of the Smithsonian Tropical Research Institute and the Max Planck Institute of Ornithology show that individual monkeys that don’t participate in conflicts prevent large groups from achieving their competitive potential.
The White-bellied Woolly Mouse Opossum, Marmosa constantiae, is listed as ‘Least Concern’ on the IUCN Red List of Threatened Species™. This small, nocturnal and arboreal marsupial is found in moist forests in eastern Bolivia, Brazil (Mato Grosso) and northwestern Argentina (Salta and Jujuy Provinces).
