摘要

我们对巴西东南部米纳斯吉拉斯州的一个大型大西洋森林保护区(Parque Estadual do里约热内卢Doce)的蝙蝠群落进行了为期10个月的调查,收集了蝙蝠物种的饮食和繁殖数据。我们在公园内的几个环境中使用地面雾网记录蝙蝠,并寻找蝙蝠的栖息地。在保护区迄今记录到的33种蝙蝠中,有24种是在本次研究中记录到的,其中12种是该公园首次记录到的。窄皮蝠粪便样本中以棘目目种子为主,细皮蝠粪便样本中以花椒属种子为主。我们还得到了蝙蝠食用木兰花果实的第一个记录。除圆齿蝠(Desmodus rotundus)在旱季繁殖活跃外,珠三角地区蝙蝠的繁殖高峰出现在雨季。我们认为,在保护区受干扰最严重的地区,圆形杜鹃和斜柳杜鹃等常见物种的相对丰度可能与不同程度的干扰有关。关键词:大西洋森林;米纳斯吉拉斯州;果树;

The bat communities (Chiroptera) of the Parque Estadual do Rio Doce, a large remnant of Atlantic Forest in southeastern Brazil
We surveyed the bat communities of a large Atlantic Forest reserve in the state of Minas Gerais, SE Brazil, the Parque Estadual do Rio Doce (PERD), over a period of ten months, collecting data on diet and reproduction of their bat species. We recorded bats using ground-level mist-nets erected in several environments within the park, and searched for bat roosts. Of a total of 33 species of bats recorded in the reserve to date, 24 bat species were recorded during this study,12 of which were first records for the park. Seeds of Cecropia predominated in the fecal samples of stenodermatine bats, and seeds of Piper were the main item in the fecal samples of Carollia perspicillata. We also got the first records of bats consuming fruits of Vismia magnoliifolia. Peaks of reproduction of bats in PERD occurred in the wet season, except for Desmodus rotundus, which was found reproductively active during the dry season. We suggest that the relative abundance of common species such as D. rotundus and Artibeus lituratus in the most disturbed areas within PERD may be correlated with distinct degrees of disturbance. Keywords: Atlantic forest, Minas Gerais, frugivory, Vismia magnoliifolia, Cecropia, bat reproduction, bioindicator.
