“…Some species can play both roles. For instance, at the early succession stages of the White Sea fouling communities the ascidian Molgula citrina Alder & Hancock acts as a dominant species living on the base substrate (Khalaman et al ., 2016), but when the populations of mussels or the ascidian Styela rustica are developed over the course of succession and displace Molgula citrina from the base substrate, this species, according to our observations, begins to live exclusively as an epibiont.…”

Comparative efficiency of Mytilus edulis as engineering species for shallow-water fouling communities on artificial structures in the White Sea

Currently, there is little comparative data on ‘efficiency’ of different engineering species, i.e. species richness, density and biomass of the associated organisms that have been supported by engineering species. The use of fouling communities makes it possible to compare the efficiency of different engineering species under the same conditions, which is necessary to obtain correct estimates and difficult to do when studying natural bottom communities. In this study, we have analysed the fouling communities in four different mussel culture farms in the White Sea to test the following hypotheses. (1) Different engineering species (mussel Mytilus edulis, solitary ascidian Styela rustica, sponge Halichondria panicea) have different assemblages of the associated vagile fauna. (2) Mytilus edulis is the most efficient engineering species, i.e. species richness, species diversity, density and biomass of the associated vagile fauna is higher in the mussel communities than in those dominated by Styela rustica or Halichondria panicea. The first hypothesis was confirmed, while the second was rejected. In all the culture farms studied, all parameters of the mussel-associated vagile fauna were not higher and in most cases were even lower than those of the fauna associated with ascidians or sponges. The reason for this seems to be the very dense packing of mussels in patches. Therefore, Mytilus edulis is not the most efficient engineering species among fouling organisms, at least in the conditions of the subarctic White Sea. The data obtained are particularly important in view of the ever-increasing volume of anthropogenic substrate and fouling communities in coastal marine ecosystems.

“…This pattern could be related to the fast colonization and growth by D. aculeata on plates posing an overall negative affect on S. balanoides recruitment (Jenkins et al 1999) or a preference for the material of the baseplates or their position in the water column. Other studies have also reported that recruitment of benthic fauna, including barnacles, is higher on the underside of plates, suggesting that algae are competitively superior on the top side (Khalaman et al 2016). Hence, modification of the settling surface appears important as indicated by the potential negative effect of algae on S. balanoides and positive effect of algae on Mytilus spp., indicating that timing of settling between different species is decisive in structuring benthic communities.…”

“…This study is a first attempt to investigate potential drivers of subtidal macrobenthic settlement and recruitment across a temporal and spatial scale in Greenland. We deployed settling plates, a standard tool in quantifying recruitment and early growth (Khalaman et al 2016), at varying distances from a glacial output in a sub-Arctic fjord system in south west Greenland, while monitoring key physical parameters such as temperature, light and salinity.…”

Subtidal benthic recruitment in a sub-Arctic glacial fjord system: Temporal and spatial variability and potential drivers

Increasing glacial discharge may influence future recruitment patterns and growth rates of marine benthos in glacial fjords as changes in surface-water temperature and salinity as well as an increase in ice-scouring events. We deployed settling plates at three spatial and temporal scales in a sub-Arctic glacial fjord system to quantify spatial and temporal variation in the recruitment rates and early growth of subtidal marine benthos, and to determine potential drivers of recruitment. We found significant spatial variation in recruitment of benthos (flora and fauna) at both the small (20 m) and large (> 30 km) scale, indicating that both abiotic and biotic factors may be important. We observed that substrate modification by bushy macroalgae facilitated Mytilus spp. settlement, yet limited Semibalanus balanoides recruitment, underlining that timing in settlement of different species is important in structuring benthic communities. Spatial variation in physical parameters, such as temperature and salinity, likely affected growth and recruitment patterns of benthos (S. balanoides). Finally, we found large spatial and temporal variation in kelp recruitment varying from none to 5866 ind. m −2 , with an annual production of more than 6000 g dw m −2 year −1 . This large growth potential of kelp suggests recruitment as a bottleneck in kelp population dynamics. Conclusively, variation in sub-Arctic benthic recruitment and growth patterns may respond to changes in temperature and salinity, yet further effort is needed to elucidate potential drivers of benthic recruitment in a fast changing Arctic environment.

The successions of benthic communities over time are strongly influenced by the first colonizers, because surface associations are facilitated by modifications to the adhesive properties promoted by primary colonizers, such as bacteria, protozoans, diatoms, algal propagules, spores, and invertebrate larvae. Bacteria are often the first colonizers on marine submerged surfaces, both organic (e.g., algae, seagrasses and invertebrates) and inorganic. However, they are promptly followed by diatoms and other microorganisms. Consequently, diatoms may represent key elements in the determination of the colonization patterns, although the development of epiphytic communities is a dynamic process influenced by several factors, including nutrient availability, the ability to synthesize and secrete extracellular material, the competition among species and the influence of grazers on individual colonizers. The process may be drastically impacted by global warming and ocean acidification due to the increasing atmospheric levels of CO2. The impact of such global stressors on benthic ecosystems, especially on the primary microphytobenthic assemblages, is still poorly investigated, and may have deleterious consequences for the benthic successions. In this review, we analyze the adhesion patterns of marine microorganisms according to their surface features and the effects of global changes on critical pioneer colonizers, such as the benthic diatoms. The results are remarkable, as they highlight emergent concerns in ecosystem conservation and the prediction of benthic communities.
