摘要: We report the first record of homing behavior a Neotropical marsupial, opossum Philander frenatus. The individual studied returned to home forest fragment where it was captured (1050 m away) crossing hostile matrix, instead moving much closer (50 distant). Movements did not follow wind or direction closest fragment, but they were significantly oriented towards fragment. probably had previous experience with release site. This unique observation suggests that ability P. frenatus overcome effects habitat fragmentation may be higher than considered previously. RESUMO: Comportamento de "homing" (Didelphimorphia, Didelphidae) em uma paisagem fragmentada da Mata Atlântica do Brasil. Relatamos o primeiro registro comportamento um marsupial neotropical, O individuo estudado retornou para fragmento onde foi capturado (distante 1050 m) atravessando matriz hostil, ao inves se deslocar muito mais proximo 50 m). Os movimentos nao seguiram direcao vento ou proximo, sendo significativamente orientados captura. provavelmente tinha experiencia previa com local soltura. Este sugere que habilidade tolerar os efeitos fragmentacao pode ser maior considerada previamente.
