Seeds consumed by waterfowl in winter: a review of methods and a new web-based photographic atlas for seed identification

摘要: Diet quantification has long been and still is one of the first steps undertaken when studying basic ecology a species. We conducted literature review techniques used to study analyse diet among waterfowl. Even though identification food items most challenging task performed granivorous waterfowl diet, there general lack reference collections support taxonomic determination resources. present here collection indexed digital pictures seeds from several French programs research into diet. Photographs are ranked by seed size or key ease identification. This freely accessible at website http://www.cebc.cnrs.fr/atlasofseeds.html, it can help wildlife researchers diets species determine items. A complete bibliography also provided, including recent papers in archeobotany useful websites.
