The Dolomites (European Alps) are a UNESCO World Heritage Site known to harbor distinctive communities of carabid beetles adapted to high-altitude environments, whose composition is shaped mainly by landform and habitat type. We aimed to assess the conservation priority of carabid beetle communities in the Brenta mountain group (Italy). We used the Index of Natural Value (INV), based on the relative frequencies and abundances of highly specialized Alpine species, as a proxy of the sensitivity to disturbance, and, thus, to the vulnerability of the carabid beetle communities to extinction. We used information on Natura 2000 habitat cover to produce a map for identifying areas of the Brenta Dolomites inhabited by the carabid beetle communities most relevant for conservation. We also report on the main differences in terms of species composition between the investigated communities. We found a positive correlation between vulnerability and altitude. Specifically, the most vulnerable communities were recorded in high-altitude habitat types (limestone cliffs and pavements, calcareous and calcschist screes, and alpine calcareous grasslands). Alkaline fens resulted in having the least vulnerable community, while those in all other habitats (bush and forests) were found to have intermediate levels of vulnerability.
多洛米蒂山脉(欧洲阿尔卑斯山)是联合国教科文组织世界遗产地,拥有适应高海拔环境的独特步甲群落,其组成主要受地形和栖息地类型影响。我们旨在评估布伦塔山脉群(意大利)步甲群落的保护优先级。我们使用自然价值指数(INV),该指数基于高度特化的高山物种的相对频率和丰度,作为对干扰敏感性的代理指标,进而作为步甲群落灭绝脆弱性的代理指标。我们利用“自然2000”栖息地覆盖信息制作了一幅地图,以识别布伦塔多洛米蒂山脉中对保护最为重要的步甲群落栖息区域。我们还报告了所调查群落之间在物种组成方面的主要差异。我们发现脆弱性与海拔高度呈正相关。具体而言,最脆弱的群落出现在高海拔栖息地类型(石灰岩悬崖和路面、钙质和钙质片岩碎石坡以及高山钙质草地)中。碱性沼泽地的群落脆弱性最低,而其他所有栖息地(灌木丛和森林)的群落脆弱性处于中等水平。
