Organisation or Individual Expertise:
I am interested in conditions and processes governing how different species and their communities operate to uniquely contribute to ecosystem functioning and, ultimately, to biosphere integrity. Environmental change is my key research focus and I like combining observational and experimental approaches to support theoretical considerations. Aquatic invertebrates show a fascinating diversity of forms and functions and are important links in energy transfer. Furthermore, inland waters are prone to a myriad of pressures, both natural and anthropogenic. Thus, I typically use freshwater invertebrates as a model system.

Organisation or Individual Expertise Keywords:

Relevant information in relation to Participation relevant experts groups

As temperature modifies both abiotic and biotic processes, the fate of refugial populations may depend on interactions of temperature with other factors, rather than on the impact of temperature alone. To explore this, using the glacial relict mysid crustacean Mysis salemaai at its southern distribution limit as a model organism, I am examining whether (1) temperature regulates sensitivity to habitat quality and (2) warming can asymmetrically affect energy budgets of ecologically similar native and introduced species. Furthermore, I am collaborating with the Population and Evolutionary Genetics Lab (Queens University Belfast, UK) to investigate, by linking molecular traits with physiological resistance, to what degree ecological impacts of climate change can be offset by adaptive potential of organisms. See for further details and updates.

Any relevant information in relation to Participation in WssTP or other relevant experts groups

Invasive species are one of the key drivers of environmental change, affecting community structure and ecosystem functions. They can exert pronounced effects on basal resources, often with cascading effects on other components of ecosystem. Mysid crustaceans have a long history of both intentional and unintentional introductions, which typically result in reducing cladoceran zooplankton populations. The resulting release of grazing pressure is likely to increase phytoplankton biomass, potentially exacerbating manifestation of nutrient enrichment and impacting water quality, but this hasn't been empirically demonstrated to date. I am currently testing such hypothesis experimentally using the globally important introduced Hemimysis anomala. See for further details and updates.
