Major research interests:

My primary research interest is the use of zooplankton-based paleoecology to investigate past conditions, changes and trends of freshwater and brackish lakes related to environmental and climate change. Paleoecological methods are often the only means of obtaining insight into past lake regimes due to the lack of alternative historical records, and they can thereby serve as an important tool for our understanding of lake responses to human impacts and climate change, and further be used for defining restoration and management strategies. In recent years, my research has focused on the reconstruction of the histories of several north temperate lakes (e.g. in Denmark, the Faroe Islands, Iceland, Greenland, Finland), by use of qualitative as well as quantitative paleoecological methods, the latter involving establishment of statistical models for inference of controlling variables for the biological structure. Through my work at the National Environmental Research Institute (NERI), I´m involved in studies of food-web interactions in sub-arctic and arctic freshwater lakes and I´m participating in the projects EUROLIMPACS (http://eurolimpacs.ucl.ac.uk, funded by EU) and CARE (Comprehensive analysis of recovery of eutrophicated lakes, funded by the Finnish Scientific Research Council), both focussing on the effects of interactions between climate and human activities on freshwater ecosystems and encompassing detailed paleolimnological investigations. More recently, I have also been working on the implementation of the EU Water Framework Directive in Denmark and the Action Plan for the Aquatic Environment 22 – Wetland. In addition, I am involved in university teaching (MSc and PhD courses) at the University of Aarhus betweentimes. At the moment, I am holding a 2-year post-doc position financed by the Carlsberg Foundation, focussing on illuminating the impact of climatically induced changes on biological structure in North-Atlantic lakes during the last 10,000 years.

Professional career and education: 

2000. M.Sc in Biology, University of Aarhus. Title: Periphyton i lavvandede søer.

2003-2005. Research Assistant, NERI, Dept. of Freshwater Ecology

2005-2008. Project Researcher, NERI, Dept. of Freshwater Ecology

Major research interest:

Periphyton and benthic primary production in lakes – with special emphasise on the effects of resources, grazing and physical conditions on the distribution, the regulation and the ecophysiology of primary producers and the benthic-pelagic coupling. Temporal and spatial distribution of the primary producers and the primary production within different lake types.

The interactive effects of global warming and eutrophication on shallow lake ecosystems (including physical and chemical conditions, community structure and dynamics, system metabolism and seasonal dynamics) – studied through long-termed experimental studies (mesocosm experiments).

Major research interests

Klaus P. Brodersen has many years of experience in multivariate numerical analysis of biological communities in marine and freshwater systems. His research activity has concentrated on (1) understanding how the physical and biological components of aquatic ecosystems (lakes, streams and spring-brooks) influence the distribution and diversity of the macroinvertebrate communities, and (2) how the lakes sedimentary records can be used to study natural long-term (millennia) and recent (decades to centuries) human-induced environmental change on local and regional scales. His work has primarily included the use of chironomid and Cladocera remains in lake sediments to quantitatively reconstruct environmental variables such as trophic conditions (lake-water chlorophyll concentrations, TP) in Denmark, and climate conditions (surface-water temperatures) in West Greenland. An important branch in the ongoing and future research is to extend the bridge between neo-limnology and palaeo-ecology by fine-tuning the reconstruction models to species-specific physiological optima (e.g. oxygen consumption) measured directly under controlled laboratory experiments with living invertebrates.
