“…The goal of the present study was to assess the relative strength of the architectural effects of aggregated barnacles, live and dead. Significant positive correlations previously observed between the numbers of large empty barnacle shells and abundances of several dominant mobile taxa (Yakovis et al 2005) suggested these effects are important in structuring habitat for the latter.…”

“…The study site was located 100 m southwest from the small island Pesya Luda (in the Solovetskiy Archipelago located in Onega Bay of the White Sea). The same place was defined as 'Site 1' in Yakovis et al (2005). The depth was 12 m and the bottom temperature was 5 to 9°C.…”

“…The assemblage of mobile taxa within the patches is different from that in the surrounding unstructured sediment and much less spatially variable at the scale of ~1000 m. The abundance of individual dependent species correlates with different properties of the patches (numbers of live barnacles, their empty shells and ascidians) (Yakovis et al 2005). However, the processes underlying these associations remain unknown.…”

The physical structure of a habitat strongly affects species composition and diversity in benthic assemblages. In the shallow subtidal zone in the White Sea in northwestern Russia, barnacles Balanus crenatus are often found in clusters on empty bivalve shells or small stones, sometimes overgrown by solitary ascidians (mainly Styela spp. and Molgula spp.). These epibenthic patches are surrounded with muddy sediment. Sediment also fills the space between barnacle shells within the patches. The assemblages of mobile macrofauna associated with epibenthic patches and surrounding unstructured sediment are different in species composition and abundance. We hypothesised that epibenthic patches at least partially affect mobile benthic organisms with their architectural properties as complex cavity-loaded structures. In a field experiment we assessed the strength of this effect, comparing unmanipulated natural epibenthic patches (E), unmanipulated patches of bare sediment (S), and patches of bare sediment with artificial imitation structures (mimics) added (M). Mimics were made of polyvinyl chloride (PVC) tubes and exposed for 1 and 2 yr (half-buried in sediment; 50 tubes × 8 to 9 sets × 2 replications). After 1 or 2 yr of exposure, the assemblages in E and M were much more similar to each other than to S (analysis of similarities, non-metric multidimensional scaling). Most species that were constantly abundant in E responded positively to the treatments. The bivalve Musculus discors and the sigalionid polychaete Pholoe minuta dominated numerically both in E and M, whereas maldanid Rhodine loveni and spionid-like Apistobranchus tullbergi dominated in S. Like many other large aggregated benthic suspension feeders, patched barnacles shape the associated assemblage of mobile benthic fauna with their architectural effect.

Epibenthic predators control mobile macrofauna associated with a foundation species in a subarctic subtidal community

Foundation species (FS) are strong facilitators providing habitat for numerous dependent organisms. The communities shaped by FS are commonly structured by interplay of facilitation and consumer control. Predators or grazers often indirectly determine community structure eliminating either FS or their principal competitors. Alternatively, they can prey on the dependent taxa directly, which is generally buffered by FS via forming complex habitats with numerous refuges. The latter case has been never investigated at high latitudes, where consumer control is widely considered weak. We manipulated the presence of common epibenthic crustacean predators to assess their effect on mobile macrofauna of the clusters developed by a FS (barnacle Balanus crenatus and its empty tests) in the White Sea shallow subtidal (65° N). While predation pressure on the FS itself here is low, the direct effects of a spider crab Hyas araneus and a shrimp Spirontocaris phippsii on the associated assemblages were unexpectedly strong. Removing the predators did not change species diversity, but tripled total abundance and altered multivariate community structure specifically increasing the numbers of amphipods, isopods (only affected by shrimp), and bivalves. Consumer control in the communities shaped by FS may not strictly follow the latitudinal predation gradient rule.
