Few sites have been well sampled for bats, and samplings in islands are even scarcer. Therefore, the objectives of the present study were: (1) to list the bat species of Ilha da Marambaia; (2) to compare richness, abundance and biomass of bat guilds found there; (3) to analyse abundance patterns of bat species; and (4) to compare richness, abundance and composition of the bat fauna among different kinds of environment. To capture bats we used mist nets set in five different environments, totalising 3559.2 net-hours, during 37 nights between October 2006 and August 2008. A total of 1,133 captures were accomplished, comprising 34 species from five families. The most abundant species was Molossus molossus. Frugivorous bats exhibited higher richness, abundance and biomass if compared to other guilds. Most species (N = 22) exhibited abundances between 1 to 10% of all captures. Sixteen species were restricted to just one of the environments sampled. The high richness may be attributed to sampling carried out in several environments, and to the capture of insectivorous species over water bodies.
对蝙蝠进行充分采样的地点很少，而在岛屿上的采样更是稀少。因此，本研究的目的是：（1）列出马兰巴亚岛的蝙蝠种类；（2）比较在该岛发现的蝙蝠群落的丰富度、丰度和生物量；（3）分析蝙蝠种类的丰度模式；（4）比较不同环境中蝙蝠动物群的丰富度、丰度和组成。为了捕获蝙蝠，我们在2006年10月至2008年8月期间的37个夜晚，在五种不同环境中设置了雾网，总计3559.2网小时。总共完成了1133次捕获，包括来自五个科的34种蝙蝠。数量最多的物种是墨西哥游离尾蝠。与其他群落相比，食果蝙蝠表现出更高的丰富度、丰度和生物量。大多数物种（N = 22）的捕获量占总捕获量的1%至10%。16个物种仅局限于所采样的一种环境。高丰富度可能归因于在多种环境中进行的采样，以及在水体上捕获食虫物种。
