Abstract

An increase in interest in the role of waterfowl in aquatic ecosystem is evident from the formation of a working group of SIL in 1992, and from the international conferences on „Aquatic Birds in the Trophic Web of Lakes”, held in Sackwille, New Brunswick, in 1991 (Kerekes and Pollard, 1994) and on „Limnology and Waterfowl - Monitoring, Management and Research”, held in Sopron, Hungary, in 1994 This report incorporates recommendations from a workshop on limnological monitoring and waterfowl, held at the latter conference The workshop arose partly from fundamental scientific needs, and partly from concerns about the lack of information on how waterfowl may be affected by major changes to aquatic ecosystems resulting from human activity, such as eutrophication, water abstraction and reclamation, acidification, and organic and other pollution. The objective of the workshop was defined as being to prescribe a minimal set of limnological variables that is desirable to measure in conjunction with waterfowl monitoring programmes, with the ultimate objectives of developing predictive models for the abundance and role in ecosystem function of waterfowl species. Such models might be derived for individual waterbodies, or for individual species or wider taxonomic groupings, over all or part of their geographical ranges...
