Bat species richness in Neotropical localities is generally higher than that of any other group of mammals, and surveys of local bat assemblages may provide useful data for conservation management plans. Although the bat fauna of the Rio de Janeiro state is currently one of the best known in Brazil, there are several localities not adequately surveyed yet, and most of them are in the mountainous regions and in the northern portion of the state. From January 2008 to November 2009, we conducted surveys of bats in three localities in the state of Rio de Janeiro (municipalities of Varre-Sai, Sumidouro, and Cantagalo), and our fieldwork constitutes the first assessment of the bat assemblages of these localities. Surveys were conducted using mist nets in four different habitat types in each locality (forest interior, forest edge, riparian forest, and open areas [pastures]). We captured a total of 148 individuals in 17 species, 14 genera and 3 families. Among them, 11 species were recorded in Sumidouro, seven in Cantagalo, and nine in Varre-Sai. Although species richness was low compared with previous surveys in other close localities, we recorded species that have been rarely sampled in Southeastern Brazil (e.g., Macrophyllummacrophyllum [Phyllostomidae]). The results reinforce the importance of sampling different habitats in short surveys to improve the number of species registered.
新热带地区的蝙蝠物种丰富度通常高于其他任何哺乳动物群体,对当地蝙蝠群落的调查可为保护管理计划提供有用数据。尽管里约热内卢州的蝙蝠动物群目前是巴西最知名的之一,但仍有几个地区尚未得到充分调查,其中大部分位于该州的山区和北部地区。2008年1月至2009年11月,我们对里约热内卢州的三个地区(瓦雷-赛伊、苏米杜鲁和坎塔加洛市)的蝙蝠进行了调查,我们的实地调查构成了对这些地区蝙蝠群落的首次评估。在每个地区的四种不同栖息地类型(森林内部、森林边缘、河岸森林和开阔区域[牧场])使用雾网进行调查。我们共捕获了148只个体,分属于17个物种、14个属和3个科。其中,在苏米杜鲁记录到11个物种,在坎塔加洛记录到7个,在瓦雷-赛伊记录到9个。尽管与其他附近地区以前的调查相比,物种丰富度较低,但我们记录到了在巴西东南部很少被采样的物种(例如,大长叶蝠[叶口蝠科])。结果强调了在短期调查中对不同栖息地进行采样以增加记录物种数量的重要性。
