论文摘要
在当前气候变化的情况下，冷适应的昆虫是阿尔卑斯山高海拔栖息地中受威胁最大的生物之一。上坡的转移和物候变化是对气候变化的最多研究的两个反应，但是在评估存在充当Refugia的高海拔地面地形的存在方面越来越兴趣。 Nebria Germari Heer，1837年（鞘翅目：Carabidae）是一种湿气和冷适应的物种，在东阿尔卑斯山的上冰片碎片上仍然显示出大量人群。这项工作旨在描述生活在冰川上碎片上的人群的生态和物候学。为此，我们分析了三个白云岩冰川的种群，它们的表面部分被石质碎片覆盖。我们发现，冰川上的碎片的特征是比周围的碎屑坡度更稳定，湿润的条件更稳定和湿润的条件更较低，而且无雪的时期较短。春季碎片上发现的人群是春季育种者，与1980年代关于白云岩高阿尔卑斯山草原的人群不同，据报道这是秋季育种者。因此，当前内布里亚（Nebria）的胚芽中似乎在冰期碎片上找到了合适的栖息地，其中微量气概的条件适合其生命周期，竞争和捕食。
In the current scenario of climate change, cold-adapted insects are among the most threatened organisms in high-altitude habitats of the Alps. Upslope shifts and changes in phenology are two of the most investigated responses to climate change, but there is an increasing interest in evaluating the presence of high-altitude landforms acting as refugia. Nebria germari Heer, 1837 (Coleoptera: Carabidae) is a hygrophilic and cold-adapted species that still exhibits large populations on supraglacial debris of the Eastern Alps. This work aims at describing the ecology and phenology of the populations living on supraglacial debris. To this end, we analysed the populations from three Dolomitic glaciers whose surfaces are partially covered by stony debris. We found that supraglacial debris is characterised by more stable colder and wetter conditions than the surrounding debris slopes and by a shorter snow-free period. The populations found on supraglacial debris were spring breeders, differently from those documented in the 1980s on Dolomitic high alpine grasslands, which were reported as autumn breeders. Currently Nebria germari seems therefore to find a suitable habitat on supraglacial debris, where micrometeorological conditions are appropriate for its life-cycle and competition and predation are reduced.
