Biodiversity and ecosystem functioning in riverine networks

Understanding the factors shaping the distribution, diversity and function of organisms is a key goal of ecology. Riverine ecosystems contain an exceptional biodiversity and are key providers of many ecosystem functions and services, and thus of high interest.

With this talk, I will firstly show how the characteristic dendritic network structure of rivers, and spatial dynamics in general, are affecting biodiversity patterns and ecosystem functioning, and how a combination of mathematical models, laboratory-based experiments and large-scale empirical data can help to understand riverine meta-ecosystems. Secondly, I will address how environmental DNA (eDNA) and remote sensing integrate biodiversity information across catchments and can be used to assess the structure of whole ecological communities at unprecedented scales. Together, this provides novel understanding and perspectives on how riverine ecosystems can be managed and preserved.
