Résumé :	In summer 2009, the effects of 6 years of landscape-level experimental nutrient enrichment on the eastern mudsnail, Nassarius obsoletus (formerly Ilyanassa obsoleta), were examined. The experiment was conducted in five tidal creeks (two nutrient-enriched, three reference creeks) in the Plum Island Estuary, Massachusetts, USA. (42A degrees 44' N, 70A degrees 52' W). After 6 years of enrichment, N. obsoletus size structure differed between treatment creeks with adult snails on average
