Projects
Projects 1991-present
- Comparative food web studies in nine Ethiopian Lakes along environmental gradients of temperature and productivity (2004 - present)
Funding: Schure-Beijerinck-Popping Fund, NWO-WOTRO.
External collaborator: Leo A.J. Nagelkerke (Wageningen University), Ferdinand A. Sibbing (Wageningen University), Eshete Dejen(Amhara Region Agricultural Research Institute, Bahir Dar, Ethiopia).
The food webs of nine Ethiopian lakes along a temperature and productivity gradient are investigated. Emphasis is on the fish communities and its food organisms. Stable isotopes are used to estimate food web structure (δ15N) and to discriminate between the littoral-benthic and the pelagic food web in the same lake (δ13C). Food web properties will be compared among the different lake ecosystems and several major hypotheses will be tested.
- Interactions among three closely related Daphnia ‘species’ in contrasting environments - a microcosm study (1995 – 2004)
Funding: KNAW Fund for visiting scientists, NWO, Schure-Beijerinck-Popping Fund.
External collaborator: Leonard V. Polishchuk (Moscow University, Russia)
Two main questions are addressed: (i) What are the effects of three types of predation on the species composition of the zooplankton community; and, (ii) What is the effect of food competition on species composition of the zooplankton community. The results obtained may help to explain the seasonal succession of these species in nature.
- Strategies to increase fish yields in tropical lakes and reservoirs (FISHSTRAT: 1999 – 2002)
Funding: EU INCO-DC grant, Vijverhof Fund, Beijerinck-Popping Fund.
External collaborators: Bandu Amarasinghe, Upali S. Amarasinghe, M.G. Ariyaratne, Tanaporn Chittapalapong, Annie Duncan, Montharop Kakkaew, Jan Kubecka, Nellie Lopez , Jacques Moreau, Leo Nagelkerke,Robert Pagulayan, Edwin Pamanian, Fritz Schiemer, Ivan Silva, David Simon, Boonson Sricharoendham. Cooperation with Institute of Environmental research, Royal Holloway, University of London, Dept of Limnology, University of Vienna, Hydrobiological Institute, Ceske Budejovice (Czech Republic), ENSAT of the Institute National Polytechnique de Toulouse, Dept of Zoology, University of Kelaniya (Sri Lanka), National Inland Fisheries Institute in Bangkok, Institute of Biology, University of the Philippines Diliman (Quezon City).
- A multidisciplinary study using an integrated limnological, fish ecological and fisheries approach in Sri Lanka, Thailand and Philippines. In cooperation with local scientists and scientists from other European countries I participated in: i) studies on the impact of small pelagic fish species in tropical lakes and reservoirs; ii) studies on size dependent productivity of microcrustacean zooplankton; iii) studies on selective feeding behaviour of zooplanktivorous fish; iv) studies on community structure of microcrustacean zooplankton in relation to environmental factors.
- Size based tools for management of freshwater fish communities (1997- 2000)
Funding: EU-FAIR
External collaborators: Magnus Appelberg, Wim van Densen, Kerstin Holmgren, Peder Jansen, Arnfinn Langeland, Joep de Leeuw (NIOO/Wageningen University), Leo Nagelkerke (NIOO/Wageningen University). Cooperation with the Fish Culture and Fisheries Group (Wageningen University), the Dept of Zoology of the Norwegian University of Science and Technology (Trondheim), and the National Institute of Freshwater Research (Drottningholm, Sweden).
Fish populations and their resources were studied over gradients of productivity in Norway, Sweden and The Netherlands. Fish communities were classified on basis of biomass-size data, both on a species basis and on basis of trophic groups. Using specific multivariate techniques key variables were identified that govern most of the diversity within and between fish communities.
- Steering role of infochemicals for food chain function and structure (SNIFFS: 1998 – 2000)
Funding: EU- Environment & Climate Programme.
External collaborators: Maarten Boersma, Wittko Francke, Robert Gaterman, Sandra Lass, Piet Spaak, Karen Wiltshire, Monika Winder). Cooperation with University of Hamburg, Max Planck Institut für Limnologie (Plön), EAWAG Swiss Federal institute for Evironmental Science and Technology (Dübendorf).
International coordinator: Koos (J.) Vijverberg
Effects of fish released infochemicals on zooplankton and of zooplankton released infochemicals on phytoplankton were studied in two ecosystems: Lake Maarsseveen (The Netherlands) and the Obersee in Arosa (Switzerland).
- Competition and resource partitioning along three dimensions in a size-structured tropical fish assemblage and its consequences for fisheries management (1991 – 1996).
Funding: NWO-WOTRO
