“…Blenniidae are represented in the intertidal zones of the Iranian coasts of the Persian Gulf and Oman Sea (Makran zone) ecoregions by 5 genera and 11 species, one of these species, that is Istiblennius lineatus, has been reported just recently (Ghanbarifardi & Malek, 2008;Mehraban & Esmaeili, 2017Mehraban et al, 2020Mehraban et al, , 2021. The subfamily Blenniinae is represented by three species of the genus Omobranchus Valenciennes, 1836, and the subfamily Salariinae is comprised by one species of Alticus Lacepède, 1800, two species of Antennablennius Fowler, 1931, three species of Istiblennius Whitley, 1943 and one species of Parablennius Miranda Ribeiro, 1915 (see Figures 1 and 2 and Table 1).…”

“…Although the combtooth blennies are easily distinguished from other blennies; however, there have been challenging debates regarding the classification within the Blenniidae (Lin & Hastings, 2013). Despite the several morphological and molecular studies (Almada et al., 2005; Bath, 2001; Hundt et al., 2014; Lin & Hastings, 2013; Mehraban et al., 2020; Springer, 1968, 1993; Springer & Williams, 1994), the morphological studies using their otoliths are scarce (Furlani et al., 2007; Rivaton & Bourret, 1999; Santificetur et al., 2017), especially from the western Indo‐Pacific region including the Persian Gulf and Oman/Makran Sea e ecoregions.…”

In the present work, the morphological characteristics of sagitta were described and analysed for 10 species of combtooth blennies (Blenniidae) inhabiting the intertidal region of the Persian Gulf and Makran zone of Oman Sea to see the taxonomic usefulness of otoliths, especially their hidden characters for species identification. Based on the obtained results, sagitta morphology could be considered as diagnostic characters distinguishing the genera Alticus, Antennablennius, Istiblennius, Omobranchus and Parablennius showing differences related to general shape, that is, elliptic/oval to triangular; shape of antirostrum and its degree of development; the degrees of convexity of ventral and dorsal margins, and shape of ostium. The common/general otolith characters shared in the all studied combtooth blennies, is the heterosulcoid condition, which is a shared character with Perciformes and Gobiiformes. The type of sulcus is ostial, and it can be considered as a plesiomorph character shared with a basal group of actinopterygian fishes. The obtained results could be useful in taxonomical, paleontological, ecological and food and feeding habits studies.

“…On the other side of the peninsula, genetic data have shown that for coral‐dependent fish species, such as C. hemistiktos (Priest et al, 2016), Nemipterus japonicus (Farivar et al, 2017), P. maculosus (Torquato et al, 2019) and Istiblennius pox (Mehraban et al, 2020), the Gulf and the Sea of Oman represent a single phylogeographical province. However, a phylogeographical study of Periophthalmus waltoni , a marine amphibious fish with terrestrial adaptations, revealed two distinct genetic clusters, one represented by the Gulf individuals and the other by individuals from the Sea of Oman.…”

Aim: Distribution patterns of lineages alone do not explain the processes underlying phylogenetic differentiation in fishes observed around the Arabian Peninsula, whose hypotheses traditionally rely on (i) Pleistocene vicariance events, (ii) successive bottlenecks, (iii) recent founder effects (iv) and large spatial gradients in physical conditions. In this study, we test the hypothesis that phylogeographical patterns of coral-dependent fish species inhabiting the peninsula may be driven by a combination of ocean circulation, larval behaviour and seascape features.Location: Arabian Peninsula. Taxa: Coral reef fish.Methods: A biophysical modelling system that relies on stochastic Lagrangian framework and Individual-Based Model was used to simulate larval dispersal through three putative barriers, by tracking three-dimensional movements of virtual particles in ocean circulation scenarios. We explored the range of dispersal capabilities across reef fish species by creating 72 hypothetical strategies, each representing a unique combination of five biological traits, namely pelagic larval duration, spawning periodicity, mortality rate, reproductive output and vertical migration. Results:The strength of the barriers was highly variable as a function of all biological traits (except reproductive output) and indicated high asymmetry of connectivity, and hence gene flow, between adjacent areas. In addition, direction and distance travelled by the virtual larvae varied according to both the geographical position of releasing site and biannual monsoonal winds. On average, larvae released during the summer exhibited a higher potential for dispersal than larvae released during the winter.Main conclusions: Our biophysical models showed that in the Arabian Peninsula, the combination of hydrodynamic, seascape features and larval traits likely affects the distribution of genetic lineages due to the interruption, reduction or asymmetry of larval movements through the putative barriers.

“…In studies with other species, the CR region has yielded equivocal results regarding the detection of genetic structure. We can find in the literature examples of findings of hypervariability and absence of genetic structure (e.g., Francisco et al, 2011;Mehraban et al, 2020;Song et al, 2020), and studies presenting hypervariability and significant genetic structure (e.g., Cunha et al, 2014;Castilho et al, 2017;Robalo et al, 2020).…”

Background Understanding the interplay between climate and current and historical factors shaping genetic diversity is pivotal to infer changes in marine species range and communities’ composition. A phylogeographical break between the Atlantic and the Mediterranean has been documented for several marine organisms, translating into limited dispersal between the two basins. Methods In this study, we screened the intraspecific diversity of 150 individuals of the Madeira rockfish (Scorpaena maderensis) across its distributional range (seven sampling locations in the Atlantic and Mediterranean basins) using the mitochondrial control region and the nuclear S7 first intron. Results The present work is the most comprehensive study done for this species, yielding no genetic structure across sampled locations and no detectable Atlantic-Mediterranean break in connectivity. Our results reveal deep and hyper-diverse bush-like genealogies with large numbers of singletons and very few shared haplotypes. The genetic hyper-diversity found for the Madeira rockfish is relatively uncommon in rocky coastal species, whose dispersal capability is limited by local oceanographic patterns. The effect of climate warming on the distribution of the species is discussed.
