Bivalve contribution to shallow sandy bottom food web off Mar Del Plata (Argentina): Inference from stomach contents and stable isotope analysis

Two infaunal species, the purple clam Amiantis purpurata and the razor clam Solen tehuelchus, are common species in the 15-20 m sandy bottom sediments between southern Brazil and central Argentina. Both species are food sources for the coastal food web, but the extent of their contribution to this f...

The gastropods Adelomelon brasiliana, Olivancillaria deshayesiana, Olivancillaria urceus and Zidona dufresnei also show evidence of consuming A. purpurata but with contribution from other species with heavier C content. According to complementary results the razor clam Solen tehuelchus may be this other species. The stable isotopic analysis shows that both clam species are at the base of the consumers in the food web. A. pupurata showed lighter C mark than S. tehuelchus, but the N isotopic mark showed higher value but still being within the same trophic level. Fil:Penchaszadeh, P.E. Universidad de Buenos Aires.
