RESEARCH GROUP

Ecology and Biodiversity Group

Updated: June 2025

Plants and animals in lakes and streams are impacted by multiple pressures including eutrophication, hydromorphological modification, forestry and climate change, which drive biodiversity loss, alter ecosystem processes, and affect delivery of the key ecosystem services provided by freshwaters.

In the Ecology and Biodiversity Group, we conduct research to better understand the mechanisms behind ecological transformation and outcomes for biodiversity and ecosystems. Our research is integrative and multiscalar, encompassing most freshwater organism groups, but focussing especially on primary producers (benthic algae, macrophytes, phytoplankton) and invertebrate consumers (zooplankton, benthic macroinvertebrates), as well as ecosystem functioning. We further develop assessment methods and tools to support improved management of freshwater ecosystems in a rapidly changing world.
