“…The idea that dispersal characteristics may have influenced the difference in population structure in S. rivulatus and S. diaspros is also consistent with previous studies that have shown some evidence of structure in Stephanolepis filefishes (Yoon et al 2012), and a lack of structure in Mediterranean rabbitfishes (Bonhomme et al 2003;Hassan et al 2003;Hassan and Bonhomme 2005;Azzurro et al 2006). It is important to note, however, that other species of Pacific rabbitfishes, do show some, albeit low, levels of population structure in Indonesia and in Guam (Priest et al 2012;Bramandito et al 2018).…”

Lessepsian fishes, entering the Mediterranean through the Suez Canal, have showed so far little genetic structure, but notable exceptions suggest the importance of life-history factors that may influence their patterns of spatial genetic variation. In this study, by sampling two invasive fishes with different life histories (the rabbitfish Siganus rivulatus and the filefish Stephanolepis diaspros ), we looked at evidence of population structure and selection at the boundary between the Red Sea and the Mediterranean (the Suez Canal), using thousands of molecular markers. Results illustrate two divergent patterns of genetic patterns, with little genetic structure in S. rivulatus and strong population structure in S. diaspros, even at such small spatial scale. We discuss differences in ecological characteristics between the two species to account for such differences. In addition, we report that in the face of both high ( S. rivulatus ) and low ( S. diaspros ) gene flow, loci under selection were uncovered, and some protein coding genes were identified as being involved with osmoregulation, which seems to be an important feature of individuals crossing the salinity-variable Suez Canal. The presence of genes under selection in populations near the Suez Canal supports the idea that selection may be active and essential for successful invasions right out of the gate.

Population genetics studies genetic variation involving gene and allele frequencies in spatial and temporal space. Genetic information can be used in conservation management through identification of phylogenetic tree reconstructions, genetic distance, genetic structure, and haplotype connectivity to maintain population existence. The samples used were primary genetic data of Siganus canaliculatus taken from Indonesian waters and secondary data accessed from the BOLD SYSTEM database from several locations, namely Indonesia, China, and Bangladesh. This research was conducted to determine the kinship of Siganus canaliculatus in Indonesia, China, and Bangladesh through genetic analysis. The results of genetic distance analysis showed that the baronang fish samples from China and Bangladesh had a close relationship with a value of 0.0534 while samples from Indonesia and Bangladesh had the farthest relationship with a value of 0.8212. Reconstruction of the phylogeny tree at maximum likelihood can show convergence within the same clade. The results of the reconstruction of the phylogeny tree showed that the species from Ambon, Bali, and Lombok came from the same clade while samples from Bangladesh had different clades with the furthest distance. The results of structural analysis and genetic diversity showed that samples from Bangladesh, China, and Indonesia had different DNA characteristics. This is correlated with the form of network integration in haplotype connectivity analysis.

Right out of the gate: the genomics of Lessepsian invaders in the vicinity of the Suez Canal

Marine organisms that enter the Mediterranean from the Red Sea via the Suez Canal are known as Lessepsian bioinvaders. In general, genetic studies of Lessepsian fishes have shown little structure between Red Sea and Mediterranean populations. Yet notable exceptions suggest the importance of life-history factors that may influence patterns of spatial genetic variation. In this study, by sampling two invasive fishes with different life histories (the rabbitfish Siganus rivulatus and the filefish Stephanolepis diaspros), we looked at evidence of population structure and selection at the boundary between the Red Sea and the Mediterranean (the Suez Canal), using thousands of molecular markers. Results illustrate two divergent patterns of genetic patterns, with little genetic structure in S. rivulatus and strong population structure in S. diaspros, even at such small spatial scale. We discuss differences in ecological characteristics between the two species to account for such differences. In addition, we report that in the face of both high (S. rivulatus) and low (S. diaspros) gene flow, loci under selection were uncovered, and some protein coding genes were identified as being involved with osmoregulation, which seems to be an important feature of individuals crossing the salinity-variable Suez Canal. The presence of genes under selection in populations near the Suez Canal supports the idea that selection may be active and essential for successful invasions right out of the gate.
