We are a very diverse group of freshwater scientists, whose fields of interests span a wide range of research questions in hydrology, community ecology, conservation biology, ecology, habitat modelling and biogeography. Our work focuses on river ecosystems and how global change will affect these systems.

We study groups of organisms from 5mm benthic macro-invertebrates to 30kg+ freshwater megafauna and the scope of our analyses range from river reaches and catchments, up to continental networks and global river networks.

Our research has four main components:

  1. Integrating flow parameters into stream analyses where we: analyse hydrological preferences and tolerances of taxa, simulate past, current and future flow conditions, integrate river characteristics into habitat models, and assess global change impacts on fish and invertebrate distribution.
  2. Evaluating freshwater megafauna diversity on a global scale, and potential conflicts associated with human activities.
  3. Assessing current and future status of freshwater biodiversity under potential global change scenarios on different spatial scales.
  4. Community ecology and trait-based research spanning multiple biological and spatial scales.
