项目摘要

Climate has often been identified as the main determinant of species' ranges, so climate change is expected to cause changes in species distributions. Recent research has identified climate-induced shifts in the altitudinal and latitudinal distribution of a variety of taxa; however the interaction between these two types of distributional shifts has rarely been studied. Elevation shifts may have the capacity to mask latitudinal shifts by delaying the extinction of species at a regional scale. Although species are likely to respond individually to climate change, the overall consequences of these changes will determine changes to biodiversity as a whole. Thus, exploring the interaction between altitudinal and latitudinal shifts is fundamental to our understanding of the potential effects of climate change on regional and global biodiversity. This project will investigate altitudinal changes in dung beetle species in five mountain regions along a latitudinal transect in Europe, where previous data are available from 14 to 26 years ago. I will test whether altitudinal occurrence of species in each area has increased since the previous survey, whether these changes are as great as would be expected given the amount of warming that has taken place, and whether these changes are related to the latitudinal position of the mountain range. Finally, I will explore the consequences of individual species shifts for both local and regional species richness.

气候通常被认为是物种分布范围的主要决定因素，因此气候变化预计会导致物种分布的变化。最近的研究已经确定了气候引起的变化，在海拔和纬度分布的各种类群，但这两种类型的分布变化之间的相互作用很少被研究。海拔变化可能有能力通过推迟区域范围内物种的灭绝来掩盖纬度变化。虽然物种可能会对气候变化作出个别反应，但这些变化的总体后果将决定整个生物多样性的变化。因此，探索海拔和纬度变化之间的相互作用对于我们理解气候变化对区域和全球生物多样性的潜在影响至关重要。该项目将调查欧洲纬度样带沿着五个山区甲虫物种的海拔变化，其中已有14至26年前的数据。我将测试是否海拔出现的物种在每个地区增加了自上次调查以来，这些变化是否是大的，因为预计已发生的变暖量，以及这些变化是否与山脉的纬度位置。最后，我将探讨个别物种的变化对当地和区域物种丰富度的影响。
