“…Genetic diversity analysis based on mtDNA and ITS-2 showed greater diversity within populations and numerous shared sequences among locations. Similar patterns have been reported for littorinids, with both direct and planktotrophic development [32][33][34], and seems to be caused by high gene flow among populations and the large littorinid population sizes.…”

“…Organisms from such environments are constantly exposed to factors that test their physiological tolerance limits; therefore, they tend to respond more rapidly to climate change via several mechanisms, such as altering their geographical distribution ranges, for instance[14,84,85]. Thus, a species sensitive to climatic fluctuation, such as L. flava, could have extended its range into the Brazilian coast in response to the progressive warming, following the LGM, a process that would have involved serial bottleneck events.Such scenarios have already been suggested for other littorinids[32][33][34]86], and would explain many of our results, such as the neutrality test results, MSN topology, and paleodistribution and coalescent simulations[87][88][89]. Nonetheless, the fossil record for littorinids from Brazil is scarce and unsuitable for testing this hypothesis.…”

Background: An important goal of population genetics studies in marine ecosystems is understanding how connectivity patterns, both spatial and temporal, are influenced by historical and evolutionary factors. When it comes to dispersion and connectivity in marine ecosystems, the role of historical and evolutionary factors over population dynamics andstructure still remains enigmatic. We evaluated the demographic history and population structure of Littoraria flava, a highly dispersive and widely distributed marine gastropod on the Brazilian intertidal zone, to predict the effects of such factors on intrapopulation divergence. To test the hypotheses that (1) the species has historically high levels of geneflow on a macrogeographic spatial scale and (2) the species distribution in rocky shores consists of subpopulations due to high degrees of environmental heterogeneity, we collected specimens along the Brazilian coastline and combined different sets of genetic markers (mitochondrial DNA, nuclear internal transcribed spacer 2, and single nucleotide polymorphisms) with niche-based modeling to predict species paleodistribution.Results: Low genetic structure was observed along the coastline, and all clustering and migration analyses supported the high gene flow over long distances hypothesis (> 3,000 km). Three genetic clusters were identified by the assignment test, each mostly composed of individuals from the three sampled regions. No fine-scale variation was observed for any location. The neutrality tests and the haplotype networks suggest that L. flava had experienced population bottleneck followed by population expansion. Both paleodistribution and coalescent simulations highlight that expansion events occurred in the Southeastern coastline during the Pleistocene interglacial cycles (21 kya).Conclusions: This is the first study on the South American coast that highlights the demographic history on a marine gastropod based on genomic markers associated with niche modelling. We found that climatic changes since the interglacial periods are potentially relevant drivers for the species distribution in the past. Our findings could enhance the understanding of the population dynamics under an evolutionary view for widely distributed non-model marine organisms.

“…In particular, the BSP analysis showed that all estimated expansion events for the East Atlantic and Mediterranean regions markedly followed the Last Glacial Maximum period (LGM, between 26,500–20,000 years before present; [51]). It has been postulated that the warming of the East Atlantic and Mediterranean Sea following the LGM might have led to the onset of favourable environmental conditions for the rapid growth and expansion of marine populations [17]. The simultaneous occurrence of demographic expansion of both regional groups supports this assumption and indicates that Atlanto-Mediterranean specimens of E. verrucosa might have responded similarly to the climatic change and new abiotic conditions.…”

“…Such integrative evidences suggest that suitable habitats within the East Atlantic and western Mediterranean (although in need to be consolidated and specified by further palaeoenvironmental and palaeogeographic evidences) might have been important marine biodiversity refugia to retain ancestral relict populations of E. verrucosa during Pleistocene climate changes. This assumption is likely supported by the outcome of recent phylogeographic studies on other Atlanto-Mediterranean marine species, which have also identified potential glacial refugia within the East Atlantic (namely across the Iberian Peninsula and Macaronesia) and the western Mediterranean [14, 17, 30, 63–65]. However, based on the analysis of only single mtDNA marker in limited sample dataset, this finding has to be considered as tentative and need to be confirmed by the analysis of another variable nuclear marker along with numerically and geographically extended datasets.…”

“…The Mediterranean Sea and the contiguous northEast Atlantic Ocean represent a suitable area to study biogeographical processes and investigate evolutionary patterns of diversification in marine species [2, 8, 16]. Indeed, the severe palaeogeographic and palaeoclimatic shifts that this region has undergone throughout its history, resulting in the onset of specific oceanographic features across its coastline, have set the stage for the impact of evolutionary and demographic processes on forging genetic variation of marine species [14, 17]. Recent phylogeographic investigations have provided evidence for the occurrence of pronounced genetic boundaries between the East Atlantic and the western Mediterranean, and between the Western and Eastern Mediterranean basins [2, 8, 15, 18–22].…”

Phylogeographic and evolutionary history analyses of the warty crab Eriphia verrucosa (Decapoda, Brachyura, Eriphiidae) unveil genetic imprints of a late Pleistocene vicariant event across the Gibraltar Strait, erased by postglacial expansion and admixture among refugial lineages

Background The Pleistocene cyclic sea-level fluctuations are thought to have markedly affected the distribution and genetic architecture of Atlanto-Mediterranean biota. Despite the acknowledged key role played by these historical events in shaping population genetic structure of marine species, little is still known about the processes involved in shaping the spatial distribution of genetic variation within intertidal species. We intended in this study to reconstruct the phylogeography of a common and widely distributed coastal species across the East Atlantic and Mediterranean Sea (the warty crab Eriphia verrucosa ), aiming to unravel potential microevolutionary processes likely involved in shaping its genetic polymorphism. For this purpose, a total of 155 specimens of E. verrucosa from 35 locations across the entire distribution range were analyzed by comparing a 453 basepairs region of the mitochondrial gene cytochrome oxidase subunit 1 (Cox1). Results Our results unveiled the prevalence of high genetic connectivity among East Atlantic and Mediterranean populations, with noticeable genetic distinctiveness of the peripheral population from the Azores. Spatio-temporal patterns of genetic diversification and demographic history allowed retrieving genetic imprints of late Pleistocene vicariant event across the Gibraltar Strait followed by subsequent postglacial expansion events for both the East Atlantic and Mediterranean regions. Integrative evidences from the outcomes of comparison of regional genetic diversification, as well as evolutionary and biogeographic histories reconstructions, support the existence of potential glacial refugia for E. verrucosa in the East Atlantic and western Mediterranean. Our results also revealed low levels of genetic variability along with recent demographic and spatial expansion events for eastern Mediterranean warty crabs, suggesting that the eastern areas within the distribution range of the species might have been recently colonized from putative glacial refugia. Conclusions These findings provide new insights into the phylogeography and evolutionary history of a common but poorly studied Atlanto-Mediterranean decapod species. Specifically, they contribute to the understanding of the impact of historical processes on shaping contemporary population genetic structure and diversity in intertidal marine species.

An important goal of marine population genetics is to understand how spatial connectivity patterns are influenced by historical and evolutionary factors. In this study, we evaluate the demographic history and population structure of Littoraria flava, a highly dispersive marine gastropod in the Brazilian intertidal zone. To test the hypotheses that the species has (1) historically high levels of gene flow on a macrogeographical spatial scale and (2) a distribution in rocky shores that consists of subpopulations, we collected specimens along the Brazilian coastline and combined different sets of genetic markers (mitochondrial DNA, ITS-2 and single nucleotide polymorphisms) with niche-based modelling to predict its palaeodistribution. Low genetic structure was observed, as well as high gene flow over long distances. The demographic analyses suggest that L. flava has had periods of population bottlenecks followed by expansion. According to both palaeodistribution and coalescent simulations, these expansion events occurred during the Pleistocene interglacial cycles (21 kya) and the associated climatic changes were the probable drivers of the distribution of the species. This is the first phylogeographical study of a marine gastropod on the South American coast based on genomic markers associated with niche modelling.
