This project aims to improve our understanding of landscape-scale patterns of species diversity, particularly invertebrates. A central question in ecology asks how habitat patchiness interacts with dispersal abilities to determine species diversity. Field tests of hypotheses are lacking due to logistic difficulties in quantifying habitat patchiness and dispersal over landscape scales. A new model proposes that fractals (a clever way of measuring environmental complexity) can capture both habitat patchiness and species' responses. Advances in river ecology have solved the logistic problems and will allow tests to compare the three main hypotheses about species diversity. The project aims to improve information about which tools will provide the best guidance, benefitting the discipline of ecology and conservation managers.

该项目旨在提高我们对物种多样性，特别是无脊椎动物的生态系统模式的理解。生态学中的一个中心问题是栖息地斑块如何与扩散能力相互作用以确定物种多样性。由于在景观尺度上难以量化生境斑块和扩散，缺乏实地假设检验。一个新的模型提出，分形（一种测量环境复杂性的聪明方法）可以捕捉栖息地的斑块和物种的反应。河流生态学的进展已经解决了逻辑问题，并将允许测试比较物种多样性的三个主要假设。该项目旨在改善有关哪些工具将提供最佳指导的信息，使生态学和保护管理人员受益。
