“…Within the West Atlantic, there appears to be no geographic structuring of A. saxatilis between the Caribbean and Brazil ( cf. Piñeros & Gutiérrez-Rodríguez, 2017 ). Divergence time estimates for the TMRCA of the geminate-clade of ( A. saxatilis WA ( A. saxatilis EA + A. hoefleri )) + A. troschelii are not constrained by any calibrations and are compatible with the closure of the Isthmus of Panama within the last 5 million years (2.4 MYA, 95% HPD 0.75–4.9 MYA).…”

“…Monophyly of A. hoefleri was only supported, but weakly so, by using many UCEs (59,853 characters in alignment), while A. saxatilis is paraphyletic in both our phylogenetic placement and A. saxatilis alignment analyses. Analysis of genetic variation across the WA range of A. saxatilis indicated a lack of genetic structuring in either mtDNA or microsatellites within the Caribbean, and a break between the Caribbean and Brazil populations of A. saxatilis in microsatellite data, but not mtDNA data ( Piñeros & Gutiérrez-Rodríguez, 2017 ). Our A. saxatilis alignment-phylogenetic-analysis ( Fig.…”

“…Our estimate of the TMRCA of the A. troschelii + ( A. saxatilis, A. hoefleri ) geminate clade is very recent, 2.4 MYA (95% HPD 0.75 –4.9 MYA). Given the capability for long distance gene flow via rafting in A. saxatilis ( Luiz et al, 2012 ; Piñeros & Gutiérrez-Rodríguez, 2017 ), a population genetics analysis that includes both sides of the Atlantic and the mid-Atlantic islands and that examines these three species as a geminate clade would be useful for demonstrating the extent of gene flow and isolation among them.…”

We investigated a pantropical sub-family and genus of damselfishes, the sergeant-majors (Pomacentridae: Abudefdufinae: Abudefduf), to identify the tempo and mechanisms of speciation in the lineage. We examined sequence capture data from 500 loci and 20 species, with multiple individuals sampled from across the geographic ranges of widespread species. Utilizing a maximum likelihood framework, as well as a time-calibrated Bayesian phylogeny, the following key questions are addressed: What is the historical tempo of speciation? What are the relative contributions of vicariant, peripatric and parapatric speciation to sergeant-major diversity? How is speciation related to major variation in trophic ecology? The approximately 20 species of sergeant-majors fall into three main lineages. The ancestral condition appears to be benthivory, which is predominant in two lineages comprising six species. The remaining species of sergeant-majors, of which there are at least 15, fall within a clade composed entirely of planktivores. This clade is sister to a benthivore clade that included one species, Abudefduf notatus, in transition to planktivory. Most speciation of sergeant-majors, which appeared ∼24 million years ago, occurred in the last 10 million years. Present distributional patterns indicate vicariant speciation precipitated by the closure of land barriers between both sides of the Atlantic and the Pacific, and the emergence of land between the Indian and Pacific Oceans. Within this backdrop, frequent oscillations in sea level over the last 10 million years also appear to have generated conditions suitable for both peripatric and vicariant speciation, and most speciation within the genus appears linked to these changes in sea level. Diversification within the genus has been concentrated in planktivorous seargeant-majors rather than benthivores. The root cause is unclear, but does not appear to be related to differences in dispersal potential, which is greater in the planktivorous species, due to the ability of their post-larval juveniles to raft with floating debris. This elevated speciation rate in planktivores and their propensity to form local endemics may reflect relaxation of selective pressures (e.g., on crypticity) that limit speciation in benthivorous sergeant-majors. Finally, our data allow us to clarify relationships of geminate sergeant-major species, indicating that there are subdivisions within the Atlantic for both benthivore and planktivore geminate pairs that may have misled previous studies.

“…Contemporary spatial patterns of a species' genetic diversity are often shaped by a combination of historical and current habitat availability and connectivity. Historical processes such as climate changes, glaciations and palaeogeographic formations may be major drivers of the extant patterns of population genetic diversity (Julio Pineros & Gutierrez-Rodriguez, 2017;Nali et al, 2020;Pinceel et al, 2013;Strugnell et al, 2012). Contemporary factors, including environmental conditions and anthropogenic disturbances, can also strongly impact the geographic distribution of population genetic variation (Cole et al, 2016;Coleman et al, 2018;Wang et al, 2017).…”

“…A species' genetic diversity is often shaped by past and current patterns of habitat availability and connectivity [2,3,7]. Extant patterns of population genetic diversity may be primarily shaped by historical processes, such as glaciations, climate changes and palaeogeographic formations [15][16][17][18]. Several recent studies suggested that climate change might cause significant changes in species distributions and biological richness, and DNA technology could also be used to track the genetic impact of adaptation [2,3].…”

The three-spot swimming crab (Portunus sanguinolentus) is mainly distributed in South East Asia. An analysis of mitochondrial control region partial sequences allows us to determine the population genetic structure, phylogeography and historical demography of this species in East Asia. The seven populations, which included 110 individuals, were collected from mainland China (Shanghai, SH, Xiamen, XM and Hong Kong, HK), Taiwan (Yilan, YL, Taichung, TC, Donggang, DG) and Singapore (Singapore, SGP). The nucleotide diversity (π) of all individuals was 0.01149, with values ranging from 0.00372 (SGP) to 0.01345 (YL). In total, 90 haplotypes have been identified, which can be divided into two major lineages: lineage A consists of specimens from SH, YL, XM, TC and DG, and lineage B corresponds to specimen from SGP. From the second to the most recent interglacial period, population expansion was observed in each lineage. However, a low level of genetic differentiation was also observed in the three-spotted swimming crab, P. sanguinolentus, according to FST values. Our results suggest that several past and present habitat configurations have shaped the genetic patterns of P. sanguinolentus until now. During Pleistocene glaciations, when sea levels were low, this species may have moved along the coast from Southeast Asia to China. It first colonized the Hong Kong area during this era. After sea levels rose and shorelines receded, it subsequently spread to the coast of mainland China.
