Our analyses showed that the two Macrodon groups consist of populations from areas that are influenced by different surface currents and therefore we can suggest that this is one of the barriers that prevents genetic flow and isolates the Macrodon populations of the tropical and subtropical groups. Considering that this species represents an important economic resource, confirmation of whether M.

The nucleotide composition of the cytochrome b sequences was Cladograms reflecting similarities between the populations were constructed using the distance matrix and maximum-parsimony techniques, deletions and insertions being treated as a fifth base in the parsimony analyses.

Even when specimens from the same or close geographic regions compose a clade, the grouping is not statistically supported. Mol Phylogenet Evol 7: Similarly, Figure 3 shows the 11 diagnostic sites 4, 19, 30, 35, 93,,of the 16S rRNA gene which differentiate the two Macrodon groups.

Rev Bras Biol 56 1: Retrieved from ” https: In marine environments the geographic structure of populations may be influenced by local environmental conditions and the life history of the species, hence the potential for species dispersal does not always predict the amount of gene flow between geographically separated populations Burton, ; Palumbi, Another important factor affecting Macrodon isolation could be the difference in reproductive periods.
Site could also anccylodon considered a good marker, as all the individuals of the tropical group possess adenine, while the nucleotide sites except for RS2 and ARG3 from the subtropical group possess guanine.

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.

The evidence presented in this paper indicates that the taxonomic status of Macrodon ancylodon should be revised, and that strategies for management and conservation of stocks from different regions of the Brazilian coast should take in consideration the results of the present investigation.
Please see our brief essay. In a study of the meristic and morphometric traits of M. Additional Information Encyclopedia of Life. 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.
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. This paper is contribution n. In the phylogenetic trees Figures 4 and 5the populations cannot be separated because individuals belonging to very distant geographical regions group together.
The Macrodon populations in the two groups probably developed mechanisms to adapt to the type of environment where they lived and this served as a barrier enhancing the geographical isolation of the populations.

The ice ages are also considered one of the phenomena that caused changes in environmental conditions, resulting in isolation and later differentiation of populations Beheregaray et al.
