“…Therefore, it has been suggested that local environmental variables have a direct effect on the timing, occurrence and duration of larval stages of marine benthic invertebrate species (Fetzer and Arntz 2008). Pelagic larval stages are a vector for dispersal and therefore have the capability to alter the abundance and distribution of benthic invertebrate species at a given site (Mileikovsky 1968;Thatje 2012). The role of seasonality on the occurrence and distribution of invertebrate larval plankton in the Arctic, however, remains scarcely known (Kuklinski et al 2013).…”

Seasonality of bivalve larvae within a high Arctic fjord

The temporal and spatial distribution of larval plankton of high latitudes is poorly understood. The objective of this work is to identify the occurrence and abundance of pelagic bivalve larvae within a high Arctic fjord (Adventfjorden, Svalbard) and to reveal their seasonal dynamics in relation to environmental variables-temperature, salinity and chlorophyll a-between December 2011 and January 2013. We applied a combination of DNA barcoding of mitochondrial 16S ribosomal RNA and morphological analysis to identify the bivalve larvae found within the plankton and demonstrate a strong seasonality in the occurrence of bivalve larvae, largely coinciding with periods of primary productivity. Seasonal occurrences of bivalve larval species differ from those known for other populations across species' biogeographic distribution ranges. Serripes groenlandicus, which is of circum-Arctic distribution, demonstrated a later occurrence than Mya truncata or Hiatella arctica, which are of predominantly boreal or cosmopolitan distribution, respectively. S. groenlandicus larvae demonstrate the most pronounced response to seasonality, with the shortest presence in the water column. Establishing latitudinal differences in the occurrence of bivalve larvae enhances our understanding of how reproductive traits of marine invertebrates may respond to climate-driven seasonal shifts in the occurrence of primary productivity.

“…Since the first study of Arctic meroplankton by Thorson (1936), only a few and mostly recent studies have focused on the occurrence of meroplankton in relation to environmental conditions (Mileikovsky 1968;Andersen 1984;Clough et al 1997;Timofeev 1998;Schlüter and Rachor 2001;Fetzer and Deubel 2006;Fetzer and Arntz 2008). Some information on meroplankton spatial and temporal distribution has been provided by investigations of Arctic macrozooplankton (Willis et al 2006;Walkusz et al 2009) or seasonality of ecosystems at local functional levels (e.g., zooplankton, phytoplankton) (Point Barrow AlaskaMacGinitie 1955; Spitsbergen- Weslawski et al 1988Weslawski et al , 1991.…”

At present, it is accepted that the Arctic currents might govern meroplankton distribution (Mileikovsky 1968;Clough et al 1997;Schlüter and Rachor 2001). However, biological processes taking place in the water column (e.g., phytoplankton blooms) also seems to influence meroplanktonic abundance (Willis et al 2006).…”

“…The appearance of meroplankton immediately followed the spring phytoplankton bloom (mid to late April), suggesting a link between these phenomena. There are also indications that the local species pool of adult organisms on the sea floor plays a crucial role in the invertebrate larval species composition and abundance observed in the water column (Mileikovsky 1968;Clough et al 1997). While there are some data on intra-annual meroplankton dynamics (e.g., Thorson 1936;Andersen 1984), studies on seasonal variation of meroplankton above the Arctic circle over an entire year are, to our knowledge, lacking.…”

Seasonality of occurrence and recruitment of Arctic marine benthic invertebrate larvae in relation to environmental variables

et al. 2013

The Arctic system is one of the regions most influenced by ongoing global climate change, but there are still critical gaps in our knowledge regarding a substantial number of biological processes. This is especially true for processes taking place during the Arctic winter but also for seasonal processes, such as the dynamics of intra-annual meroplankton occurrence. Here, we report on a 1-year study of meroplankton seasonal variability from a fjordic system in the Arctic Archipelago of Svalbard. The study combines an examination of phytoplankton, zooplankton, and hard bottom benthic settlement with measurements of environmental parameters (e.g., water temperature, particulate organic matter, and dissolved organic carbon).Samples were taken on a bi-weekly or monthly basis, and a total of 11 taxa representing six phyla of meroplankton were recorded over a 1-year period from January to December 2007. The occurrence of benthic larvae varied between the seasons, reaching a maximum in both abundance and taxon richness in late spring through early summer. Meroplanktonic larvae were absent in winter. However, settlement of benthic organisms was also recorded during the winter months (February and March), which indicates individual trade-offs related to timing of reproduction and competition. In addition, it suggests that these larvae are not relying on higher summer nutrient concentrations, but instead are dependent on alternative food sources. In parallel with meroplankton abundance, all other measured parameters, both biological (e.g., phyto-and zooplankton abundance and diversity) and physical (e.g., particulate organic matter), exhibited seasonal variability with peaks in the warmer months of the year.

“…It is, therefore, possible that they are recruited to the imitation plots from their immediate surroundings. This colonisation strategy is the only one for the arrivals with direct development (like Cirratulus cirratus, see Petersen 1999) and one of the alternatives for those with planktonic larvae (like Capitella capitata and Pholoe minuta, see Mileikovsky 1968, Butman & Grassle 1992. Higher relative abundance of P. minuta in M compared with that in E could thus possibly be due to larval depletion by barnacles or ascidians, though previously observed effects of both suspension feeders on recruitment of coexisting taxa were rather weak (Young & Gotelli 1988, Young 1989.…”

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.
