Robinson's mouse opossum (Marmosa robinsoni) in a gallery forest surrounded by savannas in the Venezuelan state of Cojedes.  Ecological niche models of each species indicate that its putative competitor M. xerophila may be responsible for the geographic isolation of some populations of M. robinsoni, highlighting the possibility of allopatry due to a biotic interaction.
