“…The creation and analysis of large data set on population genetics in species groups with different dispersal abilities linked genetic variation to constraints in movement within benthic habitats in macroinvertebrates. This finding appears consistent with a "neutral theory" explanation for marine biodiversity spatial patterns (Chust et al, 2013.…”

“…Hovel, 2003;Leibold et al, 2004;Boström et al, 2006). A faunal community living in such patchily distributed habitat has been given to the set of local communities linked by the dispersal of multiple potentially interacting species, that is, the metacommunity (e.g., Hubbell, 2001;Holyoak et al, 2005;Logue et al, 2011;Martiny et al, 2011;Chust et al, 2013a,b. The relative importance of environmental and spatial processes in determining community structures has been evaluated in various local community forms patches in both terrestrial and coastal landscapes, such as ponds, lakes, streams, estuaries, marine pelagic areas, tide pools, and intertidal rocky shores (Cottenie, 2005;Mykrä et al, 2007;Lindo and Winchester, 2009;Pandit et al, 2009;Pinto and MacDougall, 2010;Fiorentino et al, 2012;Chust et al, 2013a). In these studies, the relative contributions of environmental and spatial processes were evaluated in each taxonomic group (e.g., phytoplankton, zooplankton, macro-algae, molluscs), because the relative importance of these two mechanisms varied depending on community characteristics such as ecological traits (e.g., dispersal ability, habitat type, life history, and trophic level).…”

a b s t r a c tThe relative contributions of environmental and spatial processes in macroinvertebrate community structure (i.e., β-diversity) for three functional groups classified on the basis of dispersal ability and microhabitat selection (seagrass-associated [SA], drift-faunal [DF ], and benthic-faunal [BF ] groups) were examined in a seagrass ecosystem along the Sanriku coast of Japan. Variation partitioning was conducted to explain the environmental heterogeneity and spatial arrangement of local communities (i.e., degree of variation in the community) for each functional group. Processes determining community structure and metacommunity type differed among the functional groups. The SA group was under greater influence of environmental control, whereas the fractions of β-diversity in the DF and BF groups were explained by only spatial predictors. Thus, even if macroinvertebrate communities live in the same ecosystem, different mechanisms may determine the functional community structure, which depends on ecological traits such as dispersal ability and microhabitat. Ecological processes underlying community assembly differ among functional groups, indicating that the existence and/or dynamics of seagrass patches may affect the variation of faunal functions in an ecosystem.

“…For instance, mtDNA data have been widely used to assess the temporal and spatial fluctuations of haplotype diversity in natural populations. Many studies investigate cryptic species along environmental gradients (e.g., Jolly et al, 2005;Barroso et al, 2010), but few focus on the population structure within a specified area (e.g., Schulze et al, 2000;Craft et al, 2010;Chust et al, 2013).…”

Community structure and population genetics of Eastern Mediterranean polychaetes

et al. 2014

Species and genetic diversity are often found to co-vary since they are influenced by external factors in similar ways. In this paper, we analyse the genetic differences of the abundant polychaete Hermodice carunculata (Pallas, 1766) during two successive years at two locations in northern Crete (Aegean Sea) and compare them to other populations in the Mediterranean Sea and the Atlantic Ocean. The genetic analysis is combined with an analysis of ecological divergence of the total polychaete community structure (beta diversity) at these locations. The phylogenetic analysis of all included H. carunculata populations revealed two main clades, one exclusively found in the Mediterranean and a second occurring in both the Mediterranean and the Atlantic. Genetic diversity indices reveal unexpectedly high differences between the two Cretan populations, despite the absence of apparent oceanographic barriers. A similarly high divergence, represented by a high beta diversity index, was observed between the polychaete communities at the two locations. This comparatively high divergence of the genetic structure of a dominant species and the total polychaete community might be explained by the strong influence of local environmental factors as well as inter-specific interactions between the dominance of a single species and the members of the community.
