“…Yet, even in the marine realm, some species exhibit lifehistory traits, such as direct development and low vagility, that may promote population isolation (Colson & Hughes 2004). One such species is the common whelk Buccinum undatum L. This large subtidal gastropod, though widely distributed across the North Atlantic shelf seas, lacks a dispersing planktonic stage and has limited mobility at the adult stage (Hancock 1963, Himmelman & Hamel 1993. B. unda tum (alongside lobster Homarus gammarus, brown crab Cancer pagurus and king scallop Pecten maximus) represents a key component of the Irish inshore shellfish industry, which yields ~50 million euro and accounts for 50% of employment in the fishing sector (BIM 2005).…”

Mya arenaria — an ancient invader of the North Sea coast

Mya arenaria currently occupies a wide geographical range in the northern hemisphere, on both coasts of the Atlantic as well as on the Pacific east coast. Some authors claim it also occurs on the Pacific west coast. The species originated in the Pacific during the Miocene and was already present on both Atlantic coasts in the Pliocene. However, it died out on the edst coasts of the Pacific and the Atlantic during glaciation of the Pleistocene. With the aid of man it was reintroduced to the North Sea some 400-700 years ago and to the East Pacific last century. In the 1960s it was also introduced to the Black Sea. M. arenaria invaded new habitats by different modes:(1) natural range expansion (2) intentional as plantings, (3) unintentional as a ballast species and (4) unintentional as a byproduct of oyster transplants. Properties that may fdvor its wide range of distribution and invading success are: high fecundity; planktonic dispersal stages and life stages that lend itself to unintentional transport by humans; a broad spectrum of habitat and food preference; tolerance of a wide range of environmental conditions such as salinity and temperature; longevity, and perhaps relatively large size.

“…Until recently, it was not clear which food sources were supporting the high densities of whelks, since these animals are rarely seen feeding and stomach analyses usually revealed empty stomachs or sometimes unrecognizable materials (Himmelman and Hamel 1993). Rochette et al (1995) indicate that bivalve tissues stolen from feeding sea stars Lepasterias polaris represent a substantial portion of the diet of adult whelks.…”

-We analyzed stable isotopes of carbon and nitrogen to investigate the trophic structure of the subtidal food web around the Mingan Islands, northern Gulf of St. Lawrence, eastern Canada. All benthic consumers were enriched in 13 C (mean δ 13 C of -17.1% ) compared to particulate organic matter (POM: -23.3% ). Nitrogen stable isotope ratios ranged from 6% to 14% and the organisms studied fell into three distinct trophic groups, primary producers, primary consumers (herbivores), and predators. The sea star Crossaster papposus and the sculpin Myoxocephalus scorpius, known to be top level predators, had slightly higher δ 15 N than other predators. Although the average isotope signature of the sea star Solaster endeca placed it among regular predators, the δ 15 N increased with sea star size and large individuals could be considered as top predators. The relatively small number of organisms located at intermediate trophic levels suggests a low level of omnivory in the Mingan Islands' system, which contrasts with previously described benthic systems that exhibit a continuum between herbivores and predators. Low omnivory, in addition to low diversity, suggests that this ecosystem may be relatively unstable if exposed to natural and/or anthropogenic disturbances such as exploitation and climate change.Key words: Stable isotopes / Food webs / Omnivory / Community structure / Trophic interaction / Gulf of St. Lawrence Résumé -Nous avons analysé les isotopes stables du carbone et de l'azote pour définir la structure trophique du réseau alimentaire infralittoral (zone immergée subtidale) des îles Mingan situées dans la zone nord du golfe du SaintLaurent, côte est du Canada. La quasi-totalité des consommateurs benthiques sont enrichis en carbone 13 C (δ 13 C moyen : −17,1 % ) comparés à la matière organique particulaire (POM : -23,3 % ). Le rapport isotopique stable de l'azote se situe entre 6 % et 14 % et les organismes étudiés se classent en trois groupes trophiques distincts : les producteurs primaires, les consommateurs primaires (herbivores), et les prédateurs. L'étoile de mer, Crossaster papposus, et le poisson chaboisseau à épines courtes, Myoxocephalus scorpius, reconnus comme étant des prédateurs de niveau trophique supérieur, exhibent des rapports δ 15 N supérieurs aux autres prédateurs. Bien que la signature isotopique moyenne de l'étoile de mer, Solaster endeca, la place ici comme prédateur typique, le rapport δ 15 N augmente avec sa taille ; ce qui suggère que les individus de grande taille, chez cette espèce, peuvent être considérés comme des prédateurs de haut niveau. Le petit nombre d'organismes situés à des niveaux trophiques intermédiaires suggère un faible taux « d'omnivorie » dans le système des îles Mingan, ce qui contraste avec ce qui a été décrit précédemment pour d'autres écosystèmes marins (un continuum entre herbivores et prédateurs). Le faible taux « d'omnivorie », additionné à la faible diversité, suggère que cet écosystème peut être relativement instable face à d'éventuelles perturbatio...
