摘要

丰富程度是了解生物多样性的一个关键变量,对物种发生的估计应尽可能全面,并基于可靠的记录。采用多样化的方法来检测物种,并进行充分的采样,对于估计高度复杂的热带森林中蝙蝠的丰富度至关重要。在此,我们根据20世纪90年代和2012年至2016年的数据,分析了巴西东南部半独立大西洋森林最大的遗迹之一,名为Parque Estadial do Rio Doce(PERD)的国家保护公园蝙蝠的丰富度。基于混合采样技术,包括地面和遮篷网、声学调查和栖息地搜索,我们发现,这个PERD的单一州保护区是迄今为止记录的半熟大西洋森林中蝙蝠丰富度最高的地区。共有54种蝙蝠物种被记录为PERD,其中包括最近描述的两种蝙蝠,分别属于Thyroptera属(Thyropteriae)和Eumops属(Molossidae)。我们的数据强化了多样化采样方法的价值,以及PERD作为大西洋森林生物群落保护关键领域的作用。

Mixed Sampling Methods Reveal Elevated Bat Richness in a Semideciduous Atlantic Forest Remnant
Richness is a key variable for understanding biodiversity, and estimates of species occurrence should be as comprehensive as possible and based on reliable records. The employment of diversified methods to be able to detect species, and of adequate sampling efforts is crucial for estimating the richness of bats occurring in highly complex tropical forests. We herein analyzed the richness of bats from one of the largest remnants of the semideciduous Atlantic Forest from Southeastern Brazil, the state conservation park called Parque Estadual do Rio Doce (PERD), based on data from the 1990s and from 2012 to 2016. Based on mixed sampling techniques, including ground-level and canopy nets, acoustic surveys, and roost searching we have revealed that this single state reserve of PERD has the highest bat richness recorded to date among semideciduous Atlantic Forest locations. A total of 54 bat species have been recorded for PERD, including two recently described species from the genera Thyroptera (Thyropteridae) and Eumops (Molossidae). Our data reinforce the value of diversifying sampling methods and the role of PERD as key area for the conservation of the Atlantic Forest biome.
