The impact of top predators on the Sylt-Rømø Bight food web : assessment of harbour seal diet using stable isotope analysis
The Sylt-Rømø bight is situated in the northern Wadden Sea, between the islands of Sylt and Rømø, on the western German coast. This bight is rather well studied and its food web has been modeled, taking into account most of the trophic compartments (Baird et al. 2012). But top-predators are not yet...
