Chemical Ecology in Aquatic Systems

Christer Brönmark is a professor of Limnology at the Department of Biology/Limnology at Lund University, Sweden. His main research interests resolve around the importance of indirect interactions in freshwater food webs and how these affect the structure and function of lake ecosystems. Here, chemical cues from predators have been shown to affect the behaviour and morphology of their prey and such trait-mediated interactions may in turn affect organisms at lower trophic levels. A spectacular example of an inducible morphological defence was shown in the Crucian carp that responded to diet-related chemical cues from piscivorus fish by increasing their body depth. Brönmark has published more than 80 papers in international, peer-reviewed journals and has published a textbook (The Biology of Lakes and Ponds) at OUP (together with Lars-Anders Hansson). Besides research Brönmark has long experience of teaching at both the undergraduate and the graduate levels. Lars-Anders Hansson is a professor of Limnology at the Department of Biology/Limnology at Lund University, Sweden. His main research interests includes direct and indirect interactions in freshwater systems, specifically how organisms use plastic traits and chemical cues to simultaneously handle and compromise among multiple threats. He has performed studies on most aquatic organisms, but the main focus has been on free swimming plankton organisms and the mechanisms behind their migration and movements. Within this research area he has introduced nanoparticles as tracking devices, allowing studies on behaviour, responses to chemical cues and migratory patterns of these small organisms. Hansson is also teaching at undergraduate and graduate courses in aquatic ecology and has a long publication record and has, together with Christer Brönmark written a text book in Limnology (The Biology of Lakes and Ponds) and also co-edited a book on Lake restoration (together with Eva Bergman).
