Ulva sp. and Gracilaria sp. were found colonizing shell surfaces of an acorn barnacle, Megabalanus tintinnabulum. However, this association was not noticed in the case of Balanus amphitrite, which was a co-inhabitant. Such a difference in intergeneric interactions with the algae was examined in laboratory experiments. For this, the influence that extracts of algae, extracts of algae-associated bacteria and natural leachants from M. tintinnabulum exerted on cyprid metamorphosis of B. amphitrite was examined. Extracts of algae and associated bacteria showed no effect on the metamorphosis of B. amphitrite. This may be attributed to absence of cue-specific sugars in the exopolysaccharides and culture supernatants of bacteria. On the other hand, natural leachants of M. tintinnabulum, which showed the presence of N-acetyl-D-glucosamine, a known algal spore attractant, also inhibited metamorphosis of B. amphitrite. Thus, hosting specific epibionts could have important roles in the segregation of barnacle population.

The study of interannual changes in the structure of soft soil macrobenthic communities was carried out on the basis of material collected in three littoral sites in the waters of the Keret archipelago of the White Sea in 1983– 2013. The analyzed sites differed in biotopic heterogeneity (characteristics of the soil, degree of closure of water areas, salinity regime). This is a sandy beach in a seaward zone, and two silt-sandy beaches in a semi-enclosed and practically closed water area. The latter is located near the mouth of the Keret River, and is also under the influence of lake runoff, respectively, experiencing a slight freshening. The distance between the sites does not exceed a few kilometers. At two sites, significant changes in the structure of macrobenthos were noted, up to a change in the species dominating in biomass. The study of conjugation of fluctuations in abundance and biomass of common species showed that most taxa demonstrate an independent change in abundance indicators. However, in areas where sea grasses dominated in biomass, the change in the number of significant correlations between taxa, both in abundance and biomass, in some years occurred in accordance with fluctuations in the biomass of Zostera marina Linnaeus, 1753. It was not possible to find climatic and hydrological indicators that would explain the interannual changes in macrobenthos abundance indicators at once in all sites, despite their slight distance from each other. Thus, the conducted studies showed that the structure of macrobenthos of soft soils in the dry zone and the upper sublittoral in the region of the Keret archipelago was distinguished by spatial and temporal heterogeneity, in which one can see a reflection of the biotopic heterogeneity of habitats, features of interspecific relationships, and dynamics of the structure of settlements of dominant species. Under relatively stable climatic, hydrological, and edaphic conditions, significant changes in the structure of the White Sea littoral bottom communities of soft bottoms were mainly determined by natural changes in the structure of settlements of dominant taxa.

“…This particular year was characterized by a relatively cool winter (but see Naumov, 2013 for a description of the abnormally early ice melting), warm summer and warm following winter (Figure 2). An unusual increase in density of acorn barnacles Semibalanus balanoides was observed in 1998 due to intense settlement of juveniles, but no correlation was observed between the recruit density and adult abundance during the next year (Marfenin et al , 2013). High recruitment after the settlement in 1998 was also observed in Mya arenaria , and while the authors suggested the existence of a common mechanism regulating the recruitment rate, no factors were proposed to support the successful recruitment (Gerasimova & Maximovich, 2013).…”

Long-term population dynamics of marine invertebrates can be shaped by environmental conditions as well as biotic factors, including predation, diseases, interspecific or intraspecific competition. Towards the northern edge of species ranges the role of biotic interactions gradually decreases while the impact of climate oscillations becomes more important. This study examined the long-term changes in abundance, individual growth rates and shell shape characteristics of Macoma balthica, one of the dominant species in White Sea soft-bottom intertidal communities. To test the role of predators in changes in clam abundance, we examined the number of moonsnails Amauropsis islandica. Macoma balthica exhibited spatially synchronous population dynamics at six sites in Kandalaksha Bay, where densities of clams varied between 140 and 8500 ind. m−2 during the 21-year period of observations. Statistical modelling using generalized additive models (GAM) shows that a combination of mild winter and warm summer led to an increase in M. balthica density the following year. Predation by A. islandica had no impact on changes in M. balthica density. Growth rates of M. balthica were higher during a cool decade, but clams that lived in a warmer period were characterized by more globose shells. Our results suggest that the climate oscillations can be regarded as the key factor causing the shift in abundance of M. balthica in the White Sea during the last two decades via recruitment and survival.
