The Altitudinal Atlantic Forest is comprised of humid forest enclaves on top of the mountains surrounded by the Caatinga's xeric shrubland vegetation. It is considered a humidity refuge of endemism in semi-arid regions, and it is under intense anthropogenic pressure. Dung beetle communities are widely used as an ecological indicator of environmental conservation. However, dung beetle communities of the Altitudinal Atlantic Forest are poorly studied, and their value for biodiversity conservation in semi-arid regions is unknown. We describe and compare dung beetle communities of Altitudinal Atlantic Forest remnants located in the Brazilian Northeast semi-arid region to evaluate whether diversity patterns and species composition differ among the remnants. We captured 1,333 beetles belonging to 24 species. Only one remnant showed a statistically significant difference in diversity based on species richness and abundance, and beta diversity showed a high dissimilarity among remnants. The remnants had in common only one species, and the dominant species were distinct among them. Species composition was 16% similar among the sampled remnants, and we registered species commonly found in the Atlantic Forest, the Caatinga, and Amazonia. The structure of the dung beetle community in each remnant could be related to the historical origin and maintenance of the Altitudinal Atlantic Forest. Species compositions changed as a result of geographic location and surrounding environments, which act as filters to dung beetle species flow and establishment. We highlight the importance of the Altitudinal Atlantic Forest for the conservation and maintenance of biodiversity in the semi-arid region.

大西洋海拔森林残余的甲虫群落:多样性和组成

海拔大西洋森林由山顶上潮湿的森林飞地组成,被卡廷加的灌木丛植被所包围。它被认为是半干旱地区特有的湿气避难所,并且处于强烈的人为压力之下。粪甲虫群落被广泛用作环境保护的生态指标。但是,对大西洋大西洋沿岸的甲虫群落的研究很少,其在半干旱地区保护生物多样性的价值还不清楚。我们描述并比较了位于巴西东北半干旱地区的大西洋大西洋遗迹残存的甲虫群落,以评估这些残留物中的多样性模式和物种组成是否不同。我们捕获了1,333个属于24种的甲虫。基于物种丰富度和丰度,只有一个残留物显示出统计学上的显着差异,而β多样性显示残留物之间的高度差异。残余物只有一个共同的物种,而优势物种在它们之间是不同的。采样残留物中的物种组成相似为16%,我们注册了常见于大西洋森林,卡廷加和亚马逊地区的物种。每个残留物中的甲虫群落结构可能与大西洋原始森林的历史起源和维护有关。物种组成由于地理位置和周围环境的变化而发生变化,它们充当了甲虫物种流动和建立的过滤器。
