Twig Cutting by the Black Rat, Rattus rattus (Rodentia: Muridae), on the Ogasawara (Bonin) Islands.
v. ill. 23 cm. Quarterly Introduced black rats (Rattus rattus) have been reported to damage endemic plants of the Ogasawara Islands by gnawing. This study used seasonal field observations of plants together with analysis of rat stomach contents and age structure to help understand the cause or mecha...
