Project description
Spatial variation in ecological communities is typically understood as beta diversity, and this component is highly important in our understanding of biotic homogenisation. Despite increasing research efforts, patterns in and processes underlying beta diversity are still poorly understood for many ecosystems. We examined the effects of landscape disturbance on the beta diversity of stream macroinvertebrates and diatoms in both Brazil and Finland using well-planned large surveys and various statistical approaches. Our research was of importance in developing both basic and applied ecology, with the planned studies helping to understand the structuring of ecological communities and homogenisation of biological diversity in the face of anthropogenic changes. In addition to community-level phenomena, we also examined which environmental factors, including both natural environmental and human stress factors, affect the distribution of single species.
