“…This, in turn, leads to distinct sets of ecological interactions: from a predatordriven 'top down' system described by Paine (1966Paine ( , 2002 and Menge et al (1994) to the nutrient-driven system further south (Menge et al 1997a,b). The nearshore currents surrounding Cape Blanco are likely responsible for the genetic structure recovered across this break in the estuarine crab Hemigrapsus oregonensis (Petersen 2007). For this species, mtCOI haplotypes persisting from the mid-Pleistocene are present in all alongshore populations; however, a more recent and predominant upstream haplotype is absent in populations downstream of Cape Blanco, which is a pattern that Petersen (2007) argued was indicative of historical isolation and population expansion.…”

Our data differ from those of H. oregonensis that show a significantly deeper phylogeographic split between the 2 lineages, and suggest that coastal upwelling or selection (or a combination of both) is more likely to determine current haplotype distributions.…”

“…Comparative and integrated analysis of ecological transitions (Connolly et al 2001, Navarrete et al 2008, changes in behavior associated with these transitions (Sanford et al 2003), genetic patterns concordant with these transitions (Petersen 2007), and experimental evaluation of fitness (Sanford et al 2006) at all life stages of coastal invertebrates will ultimately provide significant insights into the function of coastal communities and the diversity they harbor. Currents and their effect on dispersal are clearly responsible for some of these observed patterns, but the environmental changes in climate and topographic conditions, which usually modulate the changes in coastal hydrography, might exert unsuspected and poorly studied selective pressures.…”

Broad scale patterns of genetic structure in coastal communities are strongly affected by both ecological transitions and larval dispersal. Along the Chilean coast, we examined 2 species of co-distributed barnacles, Jehlius cirratus and Notochthamalus scabrosus, which span an ecological transition associated with a sharp increase in larval recruitment. A distinct break in haplotype frequencies in the mitochondrial cytochrome oxidase I (mtCOI) gene was detected in N. scabrosus, with only marginal genetic structure observed in J. cirratus, suggesting significant differences in either selective pressures or dispersal ability between the species. The nuclear gene elongation factor 1α was also analyzed in N. scabrosus, and similarly suggested limited gene flow. The sharp genetic transition is downstream of the described ecological transition, effectively mirroring a genetic cline described in a different barnacle species along the North American Pacific coast.

“…Molecular tools are often employed to make indirect inferences about the levels of connectivity among natural populations [5], [6]. Molecular approaches can be particularly useful for determining the influence of such factors as hydrodynamic conditions [7], [8], habitat specificity [9], [10] and various ecological parameters (e.g., [11], [12]) on gene flow and spatial genetic structure. However, the spatial genetic structure of a species may reflect not only its current dispersal capability but also its phylogeographic history.…”

Mitochondrial DNA Reveals Genetic Structuring of Pinna nobilis across the Mediterranean Sea

et al. 2013

Pinna nobilis is the largest endemic Mediterranean marine bivalve. During past centuries, various human activities have promoted the regression of its populations. As a consequence of stringent standards of protection, demographic expansions are currently reported in many sites. The aim of this study was to provide the first large broad-scale insight into the genetic variability of P. nobilis in the area that encompasses the western Mediterranean, Ionian Sea, and Adriatic Sea marine ecoregions. To accomplish this objective twenty-five populations from this area were surveyed using two mitochondrial DNA markers (COI and 16S). Our dataset was then merged with those obtained in other studies for the Aegean and Tunisian populations (eastern Mediterranean), and statistical analyses (Bayesian model-based clustering, median-joining network, AMOVA, mismatch distribution, Tajima’s and Fu’s neutrality tests and Bayesian skyline plots) were performed. The results revealed genetic divergence among three distinguishable areas: (1) western Mediterranean and Ionian Sea; (2) Adriatic Sea; and (3) Aegean Sea and Tunisian coastal areas. From a conservational point of view, populations from the three genetically divergent groups found may be considered as different management units.

“…However, haplotype numbers in other crab species from their native range have shown to vary from 30 to 45%, e.g. the lined shore crab Pachygrapsus crassipes and the estuarine crab Hemigrapsus oregonessus (Cassone & Boulding 2006, Petersen 2007.…”

I n t e r n a t i o n a l J o u r n a l o f O c e a n o g r a p h y a n d H y d r o b i o l o g y by The Oceanological and Hydrobiological Studies is online at oandhs.ocean.ug.edu.pl pages (305-315) AbstractThe American panopeid crab species Rhithropanopeus harrisii (Gould, 1841) is listed as an non-native species in European waters. In Poland, it occurred in the 1950s at two sites at the Baltic Sea coast, the Dead Vistula River (DVR) and the Vistula Lagoon (VL). Almost 50 years later, two additional populations were identified in the Gulf of Gdańsk (GG) and its inner part, Puck Bay (PB). In the present study, we sequenced and analyzed part of the mitochondrial cytochrome oxidase subunit I gene of the four Polish populations of R. harrisii in order to assess their genetic diversity and connectivity. The analyzed sequences of a length of 989 base pairs revealed eight different haplotypes. The highest number of haplotypes (n=6) was observed in the population from GG, whereas the lowest (n=3) in VL. The most common haplotype was recorded in 37% of the analyzed individuals. Pairwise Φ ST values were mostly non-significant, with the exception of the comparison between DVR and VL (Φ ST = 0.267; P < 0.05) and between PB and VL (Φ ST = 0.194; P < 0.05), indicating a restricted gene flow or different sources of colonization.
