Since the 1990s, attacks by hematophagous bats on humans and domestic animals have been reported both on the continent and on the islands on the southern coast of Rio de Janeiro state. The density of vampire bats was investigated based on percentage of captures during control of Desmodus rotundus samplings and during bat diversity research. In the present work, 203 individuals of D. rotundus were captured from 1993 to 2009, which corresponds to 11.88% of all bat captures carried out for species control in local villages and 1.58% of all captures in faunistic inventories. The density of D. rotundus is high even on the recently occupied islands where domestic animals have been introduced. It is probable that this species dispersed from the continent to the islands due to the introduction of domestic animals.
自20世纪90年代以来，里约热内卢州南部海岸的大陆和岛屿上均有吸血蝙蝠攻击人类和家畜的报道。基于在圆叶吸血蝠采样控制期间以及蝙蝠多样性研究期间的捕获百分比，对吸血蝙蝠的密度进行了调查。在本研究中，1993年至2009年共捕获了203只圆叶吸血蝠，这相当于当地村庄为物种控制而进行的所有蝙蝠捕获量的11.88%，以及动物志清单中所有捕获量的1.58%。即使在最近引入了家畜的新占领岛屿上，圆叶吸血蝠的密度也很高。很可能由于家畜的引入，该物种从大陆扩散到了这些岛屿。
