“…Larmuseau et al (2009b) noticed the highest diversity in mtDNA in the Mediterranean samples as well. Furthermore, the highest species diversity of the 'sand goby' group is observed within the MS (Huyse et al, 2004) supporting a Mediterranean origin of P. minutus, as suggested by Gysels et al (2004a). Huyse et al (2004) estimated the origin of the species between 1.94 and 1.18 mya (early Pleistocene).…”

The Pleistocene glaciations were the most significant historical events during the evolutionary lifespan of most Holarctic species and are believed to have accelerated the speciation process in the present day sister taxa (Avise, 2000).…”

Mito-nuclear discordance in the degree of population differentiation in a marine goby

et al. 2010

An increasing number of phylogeographic studies on marine species shows discordant patterns in the degree of population differentiation between nuclear and mitochondrial markers. To understand better which factors have the potential to cause these patterns of discordance in marine organisms, a population genetic study was realized on the sand goby Pomatoschistus minutus (Pallas 1770; Gobiidae, Teleostei). Sand gobies from eight European locations were genotyped at eight microsatellite markers. Microsatellites confirmed the global phylogeographical pattern of P. minutus observed with mitochondrial DNA (mtDNA) markers and nuclear allozyme markers. Three groups consistent with the mitochondrial lineages were defined (the Mediterranean, Iberian and North Atlantic groups) and indications of a recent founder event in the northern Baltic Sea were found. Nevertheless, differences in the degree of population differentiation between the nuclear and mitochondrial markers were large (global F ST -values for microsatellites ¼ 0.0121; for allozymes ¼ 0.00831; for mtDNA ¼ 0.4293). Selection, sex-biased dispersal, homoplasy and a high effective population size are generally accepted as explanations for this mitonuclear discrepancy in the degree of population differentiation. In this study, selection on mtDNA and microsatellites, male-biased dispersal and homoplasy on microsatellite markers are unlikely to be a main cause for this discrepancy. The most likely reason for the discordant pattern is a recent demographical expansion of the sand goby, resulting in high effective population sizes slowing down the differentiation of nuclear DNA.

“…This is a result of vicariant factors ) and could be favored by their low dispersive potential (Fanta 1997), as well as ecological specificities that favor population fractionation in this family (Huyse et al 2004). The present study also highlight the importance of ribosomal sites as effective chromosomal markers in the further cytogenetic studies in gobiids species.…”

A remarkable degree of chromosomal conservatism (2n=48, FN=48) has been identified in several families of Perciformes. However, some families exhibit greater karyotypic diversity, although there is still scant information on the Atlantic species. In addition to a review of karyotypic data available for representatives of the suborders Blennioidei and Gobioidei, we have performed chromosomal analyses on Atlantic species of the families Blenniidae, Ophioblennius trinitatis Miranda-Ribeiro, 1919 (2n=46; FN=64) and Scartella cristata (Linnaeus, 1758) (2n=48; FN=50), Labrisomidae, Labrisomus nuchipinnis (Quoy & Gaimard, 1824) (2n=48; FN=50) and Gobiidae, Bathygobius soporator (Valenciennes, 1837) (2n=48; FN=56). Besides variations in chromosome number and karyotype formulas, Ag-NOR sites, albeit unique, were located in different positions and/or chromosome pairs for the species analyzed. On the other hand, the heterochromatic pattern was more conservative, distributed predominantly in the centromeric/pericentromeric regions of the four species. Data already available for Gobiidae, Blenniidae and Labrisomidae show greater intra-and interspecific karyotypic diversification when compared to other groups of Perciformes, where higher uniformity is found for various chromosome characteristics. Evolutionary dynamism displayed by these two families is likely associated with population fractionation resulting from unique biological characteristics, such as lower mobility and/or specific environmental requirements.

“…Pomatoschistus minutus, Stefanni and Thorley, 2003;Gysels et al, 2004). It seems that the intra-specific diversification of gobies has produced remarkable data in terms of ecological and genetic features, thus enhancing the attractiveness of this taxon to phylogeographers (Stefanni and Thorley, 2003;Gysels et al, 2004;Huyse et al, 2004;Verdiell-Cubedo et al, 2007;Berrebi et al, 2009;Giovannotti et al, 2009;Mejri et al, 2009).…”

“…Adults are considered to be poor swimmers because the pelvic fins have been fused into a suction disc (Miller, 1986), thereby suggesting that most large-scale dispersal is likely to depend on the short pelagic larval stage. There is an ever increasing number of studies regarding the biology and genetics of P. marmoratus (Wallis and Beardmore, 1984a,b;Miller et al, 1994;Penzo et al, 1998;Arculeo et al, 1999;Huyse et al, 2004) even if the genetic structure of its populations is yet to be studied throughout the entirety of its wide distribution area.…”

a b s t r a c tThe marbled goby Pomatoschistus marmoratus, a species inhabiting coastal Mediterranean lagoons, has been studied by measuring its mitochondrial DNA variation. This analysis revealed a Mediterranean west vs east split and, subsequently, an eastern differentiation among the Libyan-Tunisian Gulf, the Adriatic Sea and the Aegean Sea. The high cohesion between the samples collected in the vast area of western Mediterranean contrasts with the genetic mosaic of the more sub-structured eastern Mediterranean. This western homogeneity can not yet be fully explained even if a human-mediated migratory flow, due to a maritime traffic, has been posited. The pattern in the eastern basin revealed a genetic architecture possibly due to the non-migratory habit of the gobid. Within this perspective, the role of the Mediterranean lagoon habitat should be related to how much it amplifies the effects of historical (e.g. past sea-level changes) and environmental (e.g. present-day hydrographic regime) processes as regards the genetic structure of the inhabiting species.
