“…This is the case of L. bottae and L. inaequalis, historically confused (Veran 2000) or synonymised ( Chevalier 1975 ;Veran et al 1977;Wijsman-Best 1980;Scheer and Pillai 1983;Sheppard and Sheppard 1991) (Data S2) and considered widespread (Veran 2000) due to identification evidently not based on type material examination. Our results showed that the two species are actually distinct and restricted to the Red Sea and Indian Ocean where they are sympatrie (A l Tawaha et al 2019;Berumen et al 2019), while their records from the Pacifie (Crassland 1952;Chevalier 1975;Veran et al 1977;Veran 2000) were based on material here formally described as L. gibbosa sp. n. , a genetically and morphologically (Fig 7, Data SS) distinct species.…”

Accurate delimitation of species and their relationships is a fundamental issue in evolutionary biology and taxonomy and provides essential implications for conservation management. Scleractinian corals are difficult to identify because of their ecophenotypic and geographic variation and their morphological plasticity. Furthermore, phylogenies based on traditional loci are often unresolved at the species level because of uninformative loci. Here, we attempted to resolve these issues and proposed a consistent species definition method for corals by applying the genome-wide technique Restriction-site Associated DNA sequencing (RADseq) to investigate phylogenetic relationships and species delimitation within the genus Leptastrea. We collected 77 colonies from nine localities of the Indo-Pacific and subjected them to genomic analyses. Based on de novo clustering, we obtained 44,162 SNPs (3701 loci) from the holobiont dataset and 62,728 SNPs (9573 loci) from the reads that map to coral transcriptome to reconstruct a robust phylogenetic hypothesis of the genus. Moreover, nearly complete mitochondrial genomes and ribosomal DNA arrays were retrieved by reference mapping. We combined concatenation-based phylogenetic analyses with coalescent-based species tree and species delimitation methods. Phylogenies suggest the presence of six distinct species, three corresponding to known taxa, namely Leptastrea bottae, Leptastrea inaequalis, Leptastrea transversa, one characterized by a remarkable skeletal variability encompassing the typical morphologies of Leptastrea purpurea and Leptastrea pruinosa, and Please note that this is an author-produced PDF of an article accepted for publication following peer review.

Therefore, based on the combination of genomic, morphological, morphometric, and distributional data, we herein described Leptastrea gibbosa sp. n. from the Pacific Ocean and Leptastrea magaloni sp. n. from the southwestern Indian Ocean and formally considered L. pruinosa as a junior synonym of L. purpurea. Notably, mitogenomes and rDNA yielded a concordant yet less resolved phylogeny reconstruction compared to the ones based on SNPs. This aspect demonstrates the strength and utility of RADseq technology for disentangling species boundaries in closely related species and in a challenging group such as scleractinian corals.

“…In contrast, the recorded bleaching pattern provides filed evidence on the buffering properties of the northern region to the heat stress and underpins the potential role of this region as a natural coral refuge (Osman et al, 2018). In the light of the knowledge that the severity of bleaching can affect the structure of the reef and delay its recovery rate (Berumen et al, 2019;Koester et al, 2020), our study underlines that the frequency of the heat stress episodes may threaten corals over the time and can drive acute effects on the Egyptian reefs, especially at the southern coast.…”

“…Additionally, the transition zone seems to include areas, such as the outer-shelf Farasan Banks, that are exposed to upwelling in some years, but not consistently enough to cause a dip in the climatological temperatures from June to July. We suggest that these criteria provide a simple zonation of the Red Sea that can be useful in defining a range of ecological characteristics such as coral bleaching sensitivities and nutrient exposure, whereas previous considerations of Red Sea zonation have focused on faunal distributions (e.g., Spalding et al, 2007;Roberts et al, 2016;Berumen et al, 2019).…”
