“…Owing to their intensive filtration activity and ability to form dense beds, mussels play a significant role in coastal communities, providing a complex habitat, substrate and food supply for numerous associated organisms such as invertebrates, fish and birds (e.g. Bustnes 1998;Commito et al 2005;Buschbaum et al 2009;Khaitov 2013). Mytilus spp.…”

abundance of avian final hosts) on trematode infection was examined. Infection levels correlated with the interaction between local bird abundance and mussel age and density. They increased with mussel age but their dependence on mussel density and bird abundance varied among parasite genera. Prevalence and intensity increased with SSTmax for Renicola spp., but no relationship was found for Gymnophallus and Himasthla spp. The ambiguous effect of SSTmax is likely explained by the broad range of optimal temperatures for the normal functioning of trematode larvae (cercariae) infective for mussels and by the high dependence of the level of mussel infection on a combination of local ecological factors. High infection levels were observed even in localities with a low SSTmax. No mussels were infected in the most northeastern population, probably due to extreme conditions in the Arctic intertidal preventing trematode transmission. Abstract Blue mussels, Mytilus edulis, serve as second intermediate hosts for several trematode species, but little is known about the mechanisms underlying parasite infections in mussels. To reveal these mechanisms, the prevalence and intensity of trematode larvae (metacercariae in species of Gymnophallus, Himasthla and Renicola) were examined in blue mussels at 19 intertidal sites from the North Atlantic (Ireland, Iceland, Norway) to the Arctic Ocean (north-western Russia). Mussel samples were taken in [2005][2006][2007][2008].

“…The alternation between the periods of high and low abundance is typical for many White Sea invertebrates, sticklebacks and seagrasses (Khalaman & Naumov, 2009; Gerasimova & Maximovich, 2013; Khalaman, 2013; Varfolomeeva & Naumov, 2013; Ivanova et al , 2016; Khaitov & Lentsman, 2016). This alternation was found to be regular in mussel beds (Khaitov, 2013) and fouling subtidal communities (Khalaman, 2013), but irregular in soft-shell clams Mya arenaria (Gerasimova & Maximovich, 2013). Similar densities of M. balthica from the same part of the White Sea were observed in late 1940s (Sveshnikov, 1963, Table 5).…”

“…The dynamics of the White Sea intertidal communities have been studied for almost 30 years (Sergievsky et al , 1997; Sukhotin & Berger, 2013). These studies proposed several causes to describe the changes in species abundances: species interactions (Khalaman, 2013; Naumov et al , 2014), rare weather events (Naumov, 2013) and cyclic character in population recruitment (Khaitov, 2013), although the relationship between abundance and climate oscillations were not discussed.…”

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.

“…Nutrient inputs derived from the feeding activities of mussels have been shown to influence the diversity of associated species in several intertidal (Commito et al., 2008; Khaitov, 2013; Largaespada et al., 2012) and subtidal (Ezgeta‐Balić et al., 2012; Koivisto & Westerbom, 2010) mussel beds. Thus, predator NCEs on mussels might influence biodiversity in several other systems.…”

Community‐wide consequences of nonconsumptive predator effects on a foundation species

Predators can exert nonconsumptive effects (NCEs) on prey, which often take place through prey behavioural adjustments to minimise predation risk. As NCEs are widespread in nature, interest is growing to determine whether NCEs on a prey species can indirectly influence several other species simultaneously, thus leading to changes in community structure. In this study, we investigate whether a predator can exert NCEs on a foundation species and indirectly affect community structure. Through laboratory experiments, we first tested whether the predatory marine snail Acanthina monodon exerts negative NCEs on larviphagy (consumption of pelagic larvae) and phytoplankton filtration rates of the mussel Perumytilus purpuratus, an intertidal foundation species. These hypotheses stem from the notion that mussels may decrease feeding activities in the presence of predator cues to limit detection by predators. Afterwards, a field experiment tested whether the presence of A. monodon near mussel beds leads to higher colonisation rates of invertebrates that reproduce through pelagic larvae (expected under a lower larviphagy in P. purpuratus) and to a lower algal biomass on P. purpuratus shells (expected under a lower metabolite excretion in the mussels), thereby changing the community structure of the species typically found in P. purpuratus beds. The laboratory experiments revealed that waterborne cues from A. monodon limit the larviphagy and filtration rates of P. purpuratus. In turn, the field experiment showed that A. monodon cues led to greater abundances of barnacles and bivalves and a lower algal biomass in P. purpuratus beds, thus altering community structure. Overall, this study shows that a predator can indirectly affect community structure through NCEs on an invertebrate foundation species. As invertebrate foundation species are ubiquitous worldwide, understanding predator NCEs on these organisms could help to better understand community regulation in systems structured by such species.
