“…This contradicts the abundant centre hypothesis, which suggests that the greatest density of adult barnacles should be observed at the centre of their distribution range, where habitat is theoretically optimal (Sagarin & Gaines, 2002). Our results also disagree with those of Grosberg (1982), which showed that adult barnacles were most abundant in mid intertidal regions, and with those of Berger et al (2006), which showed that barnacle survivorship decreases with increasing elevation. The trend that we observed may have occurred because of the magnitude of the biotic interactions at the low intertidal zone relative to that of abiotic factors at the high intertidal zone.…”

We describe spatial trends in population structure of the barnacle, Semibalanus balanoides, across gradients of environmental stress on the Gulf of St. Lawrence coast of Nova Scotia, Canada. In the early summer of 2006, we examined vertical gradients of intertidal elevation and horizontal gradients of exposure to wave action and winter ice scour. Recruits were considerably less abundant than adults at all sites, suggesting a high post-recruitment mortality. Although adult barnacles seemed less abundant in areas subjected to strong winter ice scour than in sheltered areas, such a trend lacked statistical support. Adult barnacles were more abundant at high elevations than at low elevations, possibly as a result of vertical differences in the intensity of competition and predation. Size structure was better developed at the high intertidal zone than at the low intertidal zone, with larger organisms occurring at high elevations. In general, it appears as though biotic interactions at the low intertidal zone may play a greater role than abiotic factors at the high intertidal zone in determining the population structure of S. balanoides, although field experimentation will be necessary to confirm this notion. RESUMENDescribimos tendencias espaciales en la estructura poblacional del balano Semibalanus balanoides a través de gradientes de estrés ambiental en la costa del golfo de San Lorenzo en Nova Scotia, Canadá. En el verano temprano de 2006, examinamos gradientes verticales de elevación intermareal y gradientes horizontales de exposición al oleaje y al raspado por hielo marino invernal. Los reclutas fueron considerablemente más abundantes que los adultos en todos los sitios, sugiriendo una alta mortalidad luego del reclutamiento. Aunque los balanos adultos parecían ser menos numerosos en áreas sujetas a un raspado intenso por hielo marino invernal que en áreas protegidas, tal tendencia no mostró un sustento estadístico. Los balanos adultos fueron más numerosos en el intermareal superior que en el inferior, posiblemente como resultado de diferencias verticales en la intensidad de la competencia y predación. La estructura de tamaños estuvo mejor desarrollada en Crustaceana 81 (6): 725-736 Also available online: www.brill.nl/cr 726 ELIZABETH A. MACPHERSON & RICARDO SCROSATIel intermareal superior que en el inferior, con organismos más grandes ocurriendo en el alto intermareal. En general, parece que las interacciones bióticas fueran más importantes en el intermareal inferior que los factores abióticos en el intermareal superior en la determinación de la estructura poblacional de S. balanoides, aunque experimentos de campo serán necesarios para confirmar esta noción.

“…Scarcity of barnacle larvae in GML may be the result of other factors: high temperature, high salinity, freshwater input into GML due to limited mixing conditions, depth strata, stratification, and limited connection with the open sea may all be considered stress factors that act directly upon the development and the survival of nauplii (Berger, 2004;Berger et al, 2006).…”

“…These biogeochemical gradients provide interesting opportunities to examine their influence on life-history traits in marine benthic invertebrates (McEdward & Carson 1987, Berger et al 2006. This is particularly important, as there are comparatively few studies of variability in maternal nutrition for benthic invertebrates along unidirectional gradients of environmental conditions.…”
