项目摘要
One of the most profound drivers of changes in biodiversity today are dispersal processes of species between ranges, e.g. continents, and subsequent invasion of habitats. Once established, the ability for rapid range expansion is a key trait that determines if a species becomes invasive. The pattern of accelerated spread during range expansions has been theoretically predicted and empirically observed for invasion processes of different species and is ascribed to both, ecological and evolutionary processes. In this project, we study the accelerated spread of Mermessus trilobatus in space and time, one of the most abundant alien spider in Europe. The project is divided into two mutually complementing sub-projects that focus on the one hand on simulation models that validate theoretical predictions, and on the other hand on empirical field work as well as laboratory tests that determine specific traits of Mermessus trilobatus. By this, we intend to disentangle the complex interplay of ecological and evolutionary processes and to identify the most relevant drivers and their interaction that determine the spread of Mermessus trilobatus in Europe. The alliance of a sound empirical database, model simulations and the practicability of laboratory tests for ecological and evolutionary processes provide a unique opportunity to understand the driving mechanisms of an invasion of an arthropod species. We further explore the applicability of the methods developed in this project for other invasive species, thus providing a general framework to study invasion patterns and especially accelerated spreads.
当今生物多样性变化的最深刻驱动力之一是物种在不同分布区(如大陆)之间的扩散过程,以及随后对生境的入侵。一旦建立,快速扩展范围的能力是决定物种是否具有入侵性的关键特征。在范围扩张的加速传播的模式已经从理论上预测和经验观察到不同物种的入侵过程,并归因于这两个,生态和进化过程。在这个项目中,我们研究了欧洲最丰富的外来蜘蛛之一--三叶Mermessus trilobatus在空间和时间上的加速传播。该项目分为两个相互补充的子项目,一方面侧重于验证理论预测的模拟模型,另一方面侧重于确定Mermessus trilobatus特定性状的经验性实地工作和实验室测试。通过这一点,我们打算解开复杂的生态和进化过程的相互作用,并确定最相关的驱动程序和它们的相互作用,决定在欧洲的传播Mermessus trilobatus。一个健全的经验数据库,模型模拟和生态和进化过程的实验室测试的实用性的联盟提供了一个独特的机会,了解入侵的节肢动物物种的驱动机制。我们进一步探讨了该项目中开发的方法对其他入侵物种的适用性,从而提供了一个总体框架来研究入侵模式,特别是加速传播。
