“…The estimated divergence between C. undecimalis and C. mexicanus dates back to 23 Mya [Oliveira et al, 2014], conserving the karyotype macrostructure but displaying moderate cryptic rearrangements with a predominance of paracentric inversions. Other useful levels of microstructural change during the evolution of the genus Centropomus will be probably achieved by mapping of additional repetitive sequences in their chromosomes and inclusion of more species of this genus into the analyses.…”

“…Given their importance, a number of biological features of Centropomus have been investigated, from larval ontogeny [Kubicek et al, 2018] to growth [Perera-García et al, 2013], natural and induced reproduction [IbarraCastro et al, 2011;Perera-García et al, 2011;Cruz-Botto et al, 2018], physiological traits [Rocha et al, 2005], and genetic and phylogenetic aspects [Tringali et al, 1999;Oliveira et al, 2014]. However, cytogenetic data are still scarce for the whole Centropomidae family, hampering the proper understanding of the evolutionary processes that shaped this fish group.…”

Centropomus is the sole genus of the Centropomidae family (Teleostei), comprising 12 species widely distributed throughout the Western Atlantic and Eastern Pacific, with 6 of them occurring in the Western Atlantic in extensive sympatry. Their life history and phylogenetic relationships are well characterized; however, aspects of chromosomal evolution are still unknown. Here, cytogenetic analyses of 2 Centropomus species of great economic value (C. undecimalis and C. mexicanus) were performed using conventional (Giemsa, Ag-NOR, and fluorochrome staining, C- and replication banding) and molecular (chromosomal mapping of 18S and 5S rDNA, H2A-H2B and H3 hisDNA, and (TTAGGG)_n repeats) approaches. The karyotypes of both species were composed of 48 solely acrocentric chromosomes (2n = 48; FN = 48), but the single ribosomal site was located in varying positions in the long arms of the second largest chromosome pair. Replication bands were generally similar, although conspicuous differences were observed in some chromosome regions. In both species, the histone H3 genes were located on 3 apparently homeologous chromosome pairs, but the exact position of these clusters differed slightly. Interspecific hisDNA and rDNA site displacements can indicate the occurrence of multiple paracentric inversions during the evolutionary diversification of the Centropomus genomes. Although the karyotypes remained similar in both species, our data demonstrate an unsuspected microstructural reorganization between them, driven most likely by a series of paracentric inversions.

“…The most variable nuclear locus was the intron of the IGF 2 gene, which presented a degree of polymorphism comparable to that observed in the mitochondrial Control Region, indicating that it is a potentially useful marker for population-level and phylogeographic studies in lutjanids, as observed for Centropomus [75]. …”

High Levels of Genetic Connectivity among Populations of Yellowtail Snapper, Ocyurus chrysurus (Lutjanidae – Perciformes), in the Western South Atlantic Revealed through Multilocus Analysis

In the present study, five loci (mitochondrial and nuclear) were sequenced to determine the genetic diversity, population structure, and demographic history of populations of the yellowtail snapper, Ocyurus chrysurus, found along the coast of the western South Atlantic. O. chrysurus is a lutjanid species that is commonly associated with coral reefs and exhibits an ample geographic distribution, and it can therefore be considered a good model for the investigation of phylogeographic patterns and genetic connectivity in marine environments. The results reflected a marked congruence between the mitochondrial and nuclear markers as well as intense gene flow among the analyzed populations, which represent a single genetic stock along the entire coast of Brazil between the states of Pará and Espírito Santo. Our data also showed high levels of genetic diversity in the species (mainly mtDNA), as well a major historic population expansion, which most likely coincided with the sea level oscillations at the end of the Pleistocene. In addition, this species is intensively exploited by commercial fisheries, and data on the genetic structure of its populations will be essential for the development of effective conservation and management plans.

“…Earlier analyses of C. undecimalis collected off the coast of Florida based on mitochondrial DNA hap- lotypes (Tringali and Bert 1996) were consistent with a hypothesis of restricted gene flow between the Atlantic and Gulf populations. Analyses of mitochondrial DNA haplotypes also indicated genetic differentiation and structuring of Centropomus species off the Brazilian coast (de Oliveira et al 2014). However, there was no evidence of genetic structure in the stocks within the Florida Gulf or within the Atlantic (Tringali et al 2008), and no pattern of isolation between C. undecimalis captured in marine (Gulf of Mexico) and freshwater (San Pedro River) environments was observed (Hernandez-Vidal et al 2014).…”

Summary:In this study, we used microsatellite markers to examine the genetic structures of Centropomus undecimalis (Bloch, 1792) and Epinephelus marginatus (Lowe, 1834) populations collected from artisanal fishing sites along a stretch of coastline in southeastern Brazil. Based on F-statistics, there was no significant genetic differentiation evident in any C. undecimalis samples (F ST =0.012). However, Bayesian clustering, principal component analysis (PCA) and discriminant analysis of principal components (DAPC) results suggested that there were most likely two clusters, with no relation to geographic areas. The bottleneck results showed no significant values and the effective population sizes (N e ) for the two genetically differentiated groups were large and similar. In contrast, for E. marginatus populations, the microsatellite loci showed no population subdivisions. The F ST value was low and non-significant (F ST =0.008), a Bayesian analysis indicated one cluster, and a PCA showed that all samples from different geographical sites shared the same genetic structure. The bottleneck results exhibited significant differences, and a low N e was observed. The results of the genetic study of these two species along the southeastern Brazilian coast suggest that the distinct genetic structure of each species should be taken into account as management units for the conservation of their genetic diversities.Keywords: small-scale fisheries; microsatellites; genetic diversity; common snook; dusky grouper; bottleneck. Estructura genética poblacional de dos especies piscícolas, una de estuario y una de arrecife, explotados por la pesca artesanal brasilera Resumen: En este estudio se han utilizado marcadores microsatélites para examinar la estructura genética de Centropomus undecimalis (Bloch, 1792) y Epinephelus marginatus (Lowe, 1834) en localidades de pesca artesanal localizadas a lo largo de la costa del sudeste de Brasil. Los estadísticos de diferenciación poblacional (F-statisctics) no presentaron diferenciación genética entre las muestras de C. undecimalis (F ST =0.012). Sin embargo, los resultados de los análisis basados en clústeres bayesianos, componentes principales (PCA) y análisis discriminante de componentes principales (DAPC) sugieren la posible presencia de dos clústeres diferenciados genéticamente, pero sin ninguna relación con las áreas geográficas. Los resultados del análisis de cuello de botella poblacional no son significativos con valores de tamaño efectivo poblacional (N e ) elevados y similares entre los dos clústeres. Por el contrario, en E. marginatus, los análisis basados en microsatélites no muestran ningún patrón de subdivisión genética. El valor de F ST es bajo y no significativo (F ST =0.008), el análisis Bayesiano indicia un solo clúster y el PCA determina que todas las muestras de las diferentes localidades geográficas comparten la misma estructura genética. El análisis de cuello de botella muestra diferencias significativas con la observación de una baja N e . Los resultados de los anál...
