But he notes that the study does not tease out whether the fragmentation or the rat invasion had a greater impact. Robin Chazdon, an ecologist at the University of Connecticut, Storrs, notes that the mechanism by which the invasive rats contributed to the demise of native species—whether they devoured available food or introduced new diseases—is not clear. "These findings are not directly relevant to forest fragments in terrestrial landscapes," where animals from surrounding areas could recolonize the isolated patch, she says. |
