Water Team Presentation
At the Aquatic Ecology Unit, they perform research at a multitude of organisational levels, from molecules to organisms, and from individual behaviors to ecosystem processes. Presently, they are involved in research on e.g. climate change effects on aquatic systems, regime shifts in shallow lakes, dispersal and migration of aquatic organisms, population genetics, predator-prey interactions, effects of pesticides and endocrine disruptors and sustainable fisheries. They have strong national and international collaborations.
Associate Professor Senior Lecturer
I received my PhD at Lund University in 2000, studying the influence of ecological processes on the accumulation of persistent organochlorines in aquatic ecosystems. During my post-doc at MIT, Cambridge Ma, I studied the plasticity of marine microorganisms under environmental stress. Since then my research interests have broadened to include both the environmental influence on contaminant transport and uptake, and the ecological effects of contaminants on populations, communities and ecosystems. Our research on bioaccumulation and effects of persistent organic chemicals is still ongoing. Presently, we are conducting research on the fate and effects of emerging contaminants, in particular pharmaceuticals and engineered nanoparticles
The drivers of my research are the needs to accurately predict exposure and effects of contaminants at ecosystem level to enable scientifically sound ecological risk assessments of past, present and future chemicals released from anthropogenic activities. A future goal of our research is to enable extrapolation of effects of contaminants at individual level, to population, community and ecosystem level. That would enable predictions and risk management at the proper level of our protection goals.
Professor in limnology.
Currently focuses on three main projects:
- Phenotypic integration in the landscape of fear,
- Effects of climate change on freshwater ecosystems,
- Nanoparticles in the environment.
Effects of climate change on freshwater ecosystems
Aquatic ecosystems will in the future face simultaneous threats from several environmental drivers such as changes in climate and water color (“brownification”). These threats will not be independent, but will act in concert leading to unpredictable, non-intuitive and hitherto unknown synergistic effects on species interactions, ultimately affecting ecosystem functioning of aquatic systems and their usefulness as resources for humans. So far, few investigations have studied the interactive effects of such multiple environmental drivers on aquatic systems. Our research group is using a combination of field monitoring and large-scale experiments to improve our understanding of how our “future water” will function. This research was funded by EU BiodivERsA and was 2017 assessed by the funder as a “success story”.
Researches the classical evolutionary question - the origin of species, as well as phenotypic plasticity and how scientific results are published. He is a marine biologist by training and primarily use marine molluscs as model organisms.
Johan Hollander teaches graduate and undergraduate courses in marine biology, evolutionary ecology, as well as in statistics and experimental design.
