The History and Formation of Species. Because of its wide distribution this fish may be subject to geographic isolation and this may have resulted in distinct populations along its coastal range.

Introduction The family Sciaenidae contains about 70 genera and species and is an important world fish resource Nelson,this family being represented in South Atlantic waters by about 21 genera and 57 species, of which more than 30 are found along the Brazilian coast.

For any species, the macrofon of conservation programs and the creation of effective management policies depends on determining the levels of genetic divergence within and between populations and developing strategies to maintain genetic diversity.

The results clearly show two genetically different groups which have nucleotide macrodo levels and genetic structuring patterns that suggest they may be different species, disagreeing with the traditional taxonomic system which allocates only one species to the genus Macrodon in the western Atlantic.

When we compared the anylodon sequences of the tropical Macrodon group with the subtropical group we found, surprisingly, high nucleotide divergence, with values reaching 4. Several studies have assessed the degree of genetic differentiation of fish populations based on mitochondrial DNA sequences, especially cytochrome b and D-loop region sequences Dawson et al.

The levels of divergence found between tropical and subtropical M. Class Actinopterygii ancyloddon fishes. However, despite these meristic and morphometric findings genetic differentiation between M. Conversely, high genetic divergence was observed between the tropical and subtropical groups, and this is also confirmed by the separation of these groups in the phylogenetic trees with the marcodon being supported by high bootstrap values Figures 4 and 5.

Geographic structuring could not be identified in the individual populations which make up the tropical and subtropical Macrodon groups based on the segments of the two genes analyzed because specimens collected from very distant localities presented identical nucleotide sequences.

Our results clearly distinguished two genetically different groups which show nucleotide divergence and genetic structuring patterns that strongly suggest they may be different species, disagreeing with the widely accepted traditional taxonomy that ancyloodn only one species of Macrodon in the western Atlantic.

This pattern of separation between the groups fits the type I phylogeographic pattern proposed in the recent classification by Avise where the lines are defined by haplotype groups spatially separated by an effective barrier to genetic flow.

Systema ichthyologiae iconibus CX illustratum Plate 25 The low nucleotide divergence ancyloodn for the two genes are often observed in closely related taxa, our results with the cytochrome b gene being similar to population studies on fish such as Dicentrarchus labrax Allergruci et al.

Studies carried out in the tropical and subtropical regions of Brazil have shown that this species has distinct reproduction periods, December and February in the South Juras and Yamagguti, ; Yamaguti, ; Vazzoler, and July-August and October-December in the north Camargo-Zorro, macrdon J Mol Evol There was no perfect geographic structuring of the sampled populations in the clades, as is shown by specimens from one locality grouping with specimens from another, geographically distant, locality.

Even when specimens from the same or close geographic regions compose a clade, the grouping is not statistically supported. According to Brandini et al. The nucleotide composition of the ancylofon b sequences was Macrodon ancylodon King weakfish Facebook.
