“…Beyond the differences found between basal and derived orders in fish phylogeny, the tendency towards chromosome acrocentrization seems to occur even within groups at the family level. For example, the ancestral karyotype reconstruction analysis performed in the family Carangidae has shown that although the diploid number 2n = 48 is conserved in the family, karyotypes with higher numbers of biarmed chromosomes (m/sm) are predominant in basal clades, whereas a higher proportion of acrocentric chromosomes with a decreasing tendency or complete elimination of biarmed chromosomes is observed in most derivative species [30]. In the case of Lebiasina , which is considered basal in the family, the presence of biarmed chromosomes must represent a basal condition for the family, a fact that is also reinforced by the absence of any ITS signal on their chromosomes (Figure 4).…”

We present the first cytogenetic data for Lebiasina bimaculata and L. melanoguttata with the aim of (1) investigating evolutionary events within Lebiasina and their relationships with other Lebiasinidae genera and (2) checking the evolutionary relationships between Lebiasinidae and Ctenoluciidae. Both species have a diploid number 2n = 36 with similar karyotypes and microsatellite distribution patterns but present contrasting C-positive heterochromatin and CMA3+ banding patterns. The remarkable interstitial series of C-positive heterochromatin occurring in L. melanoguttata is absent in L. bimaculata. Accordingly, L. bimaculata shows the ribosomal DNA sites as the only GC-rich (CMA3+) regions, while L. melanoguttata shows evidence of a clear intercalated CMA3+ banding pattern. In addition, the multiple 5S and 18S rDNA sites in L. melanogutatta contrast with single sites present in L. bimaculata. Comparative genomic hybridization (CGH) experiments also revealed a high level of genomic differentiation between both species. A polymorphic state of a conspicuous C-positive, CMA3+, and (CGG)n band was found only to occur in L. bimaculata females, and its possible relationship with a nascent sex chromosome system is discussed. Whole chromosome painting (WCP) and CGH experiments indicate that the Lebiasina species examined and Boulengerella maculata share similar chromosomal sequences, thus supporting the relatedness between them and the evolutionary relationships between the Lebiasinidae and Ctenoluciidae families.

“…Similar phylogeographic breaks to those reported here in E . vomerinus , particularly the break separating the North group, were also detected in other reef fish species, such as Chromis multilineata (Pomacentridae) and Caranx lugrubis (Carangidae) [ 56 , 57 ], suggesting that these phylogeographic barriers might work as a useful biogeographic hypothesis for co-distributed species. Together, our results suggest significant evolutionary diversification within E .…”

Population Structure of the Rockpool Blenny Entomacrodus vomerinus Shows Source-Sink Dynamics among Ecoregions in the Tropical Southwestern Atlantic

The Tropical Southwestern Atlantic is characterized by prominent ecosystems with large-scale oceanographic complexity. Yet, the evolutionary processes underlying genetic differentiation and connectivity in this region remain largely unknown. Entomacrodus vomerinus (Valenciennes, 1836) is a demersal fish with planktonic larvae endemic to this marine province, inhabiting shallow tidal pools in continental and oceanic reef environments. We evaluated the population structure, genetic diversity and gene flow of E. vomerinus using mitochondrial data (CYTB and COI) and nuclear (rhodopsin, RHO) DNA sequences. We sampled a total of 85 individuals, comprising 46 from three oceanic archipelagos with varying distance from the coast (São Pedro and São Paulo—SS, Fernando de Noronha—FE and Rocas Atoll—RA) and 39 from two localities in northeastern Brazilian coast (Rio Grande do Norte—RN and Bahia—BA). Multilocus analysis revealed the presence of three Evolutionarily Significant Units—ESUs (SS, FE+RA, and RN+BA), which are in accordance with distinct marine ecoregions. Coalescent analyses showed that the central ESU has a larger effective population size than the other two, suggesting strong asymmetries in the genetic diversity across the species range. Moreover, they showed that gene flow is highly asymmetric, suggesting a source-sink dynamics from the central ESU into the remaining ones, in agreement with oceanic currents. Together, these results provide insights in the evolutionary mechanisms facilitating diversification in this marine province.

“…In groups of fish with conserved chromosomal characteristics, the mapping of 18 and 5S sequences using dual-color FISH, as used for C. bartholomei, C. latus, and C. lugubris allows analysis of karyotype evolution, rearrangements involved in diversification, and discrimination of species or populations (Accioly et al, 2012;Jacobina et al, 2013). The presence of 18S rDNA sites on the same homeolog pair (pair 1) and 5S rDNA sites located at the same position (short arm) of pair 15 in C. bartholomei and C. latus reinforce the conservation and phylogenetic proximity among the species in these 2 genera (Carangoides and Caranx), which are considered by some authors to belong to the same genus (Smith-Vaniz, 1984;Reed et al, 2002).…”

ABSTRACT. In Carangidae, Caranx is taxonomically controversial because of slight morphological differences among species, as well as because of its relationship with the genus Carangoides. Cytogenetic data has contributed to taxonomic and phylogenetic classification for some groups of fish. In this study, we examined the chromosomes of Caranx latus, Caranx lugubris, and Carangoides bartholomaei using classical methods, including conventional staining, C-banding, silver staining for nuclear organizer regions, base-specific fluorochrome, and 18S and 5S ribosomal sequence mapping using in situ hybridization. These 3 species showed chromosome numbers of 2n = 48, simple nuclear organizer regions (pair 1), and mainly centromeric heterochomatin. However, C. latus (NF = 50) and C. bartholomaei (NF = 50) showed a structurally conserved karyotype compared with C. lugubris (NF = 54), with a larger number of 2-armed chromosomes. The richness of GC-positive heterochromatic segments and sites in 5S rDNA in specific locations compared to the other 2 species reinforce 9629 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 13 (4): 9628-9635 (2014) rDNA genes in the chromosomes of Caranx and Carangoides spp the higher evolutionary dynamism in C. lugubris. Cytogenetic aspects shared between C. latus and C. bartholomaei confirm the remarkable phylogenetic proximity between these genera.
