There is evidence that landscape structure has a substantial influence on the within species genetic variability which is considered one of the three main levels of biodiversity. In this project we aim to study the combined effects of contemporary and historic landscape structure on both neutal and adaptive genetic diversity of ground beetle populations. We choose three ground beetle species of different powers of dispersal and habitat preference to be studied in the Biodiversity Exploratories. The species occur frequently on the experimental plots. Because of their pronounced habitat preference and their generally small dispersal power they are likely to be influenced by landscape changes. Methods comprise analyses of landscape history, investigation of genetic markers (microsatellites, allozymes) and the analyses of hindwing development. Together with data from the project (landuse, connectivity, species richness of different groups) the collected data will be analyzed in respect of (1) the genetic structure and differentiation of the studied ground beetle populations, (2) correlations between the different levels of biodiversity and (3) possible adaptive processes which might have been triggered by the landscapes’ contemporary or historical structure.

有证据表明，景观结构对物种内部遗传变异具有重大影响，遗传变异被认为是生物多样性的三个主要水平之一。在本项目中，我们旨在研究当代和历史景观结构对地面甲虫种群中性和适应性遗传多样性的综合影响。选择3种不同扩散能力和生境偏好的地面甲虫，在生物多样性探测站进行研究。该物种在试验田频繁出现。由于它们明显的生境偏好和通常较小的扩散能力，它们很可能受到景观变化的影响。方法包括景观史分析、遗传标记（微卫星、等位酶）调查和后发分析。结合项目收集的数据（土地利用、连通性、不同类群的物种丰富度），收集的数据将在以下方面进行分析：(1)所研究的地面甲虫种群的遗传结构和分化；(2)不同生物多样性水平之间的相关性；(3)景观当代或历史结构可能引发的适应过程。
