Another important factor affecting Macrodon isolation could be the difference in reproductive periods. By using this site, you agree to the Terms of Use and Privacy Policy. J Mol Evol 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 mscrodon Burton, ; Palumbi, Results Nucleotide composition Table 2 shows that 29 different cytochrome b sequences were obtained from 53 M.

Table 2 shows that 29 different cytochrome b sequences were obtained from 53 M. Because of its wide distribution, M. Conversely, high genetic divergence was ancyoldon between the tropical and subtropical groups, and this is also confirmed by the separation of these groups in the phylogenetic trees with the nodes being supported by high bootstrap values Figures 4 and 5.

According to YamagutiM. Wikibooks 0 entries edit. Phylogenetic analyses The two DNA segments studied did not show any indication of saturation in their sequences, so that both could be used in the phylogenetic analyses. University of Hawaii, Honolulu, 46 pp. The degree of confidence for the groups on the ancylidon tree was evaluated by bootstrap replicates Felsenstein, ancylodn Figure 2 shows 24 nucleotide sites 45, 46, 55,,,,,, in the cytochrome b gene that can be clearly distinguished in the tropical and subtropical Macrodon groups.


Wikiversity 0 entries edit. Estimation of the number of nucleotide substitutions was conducted for both genes using the method of Tamura and Neithe parameter of the gamma distribution 0. A possible cause for the marked genetic differentiation of the tropical and subtropical Macrodon groups could be patterns of oceanic circulation caused by surface marine currents, e.

Views Read View history. 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.

Stepien has suggested that the barrier of warm water in the south of the Gulf of California is the cause of the isolation and consequent genetic divergence which occurs among spotted sand bass Paralabrax maculatofasicatus populations in the Gulf of California and the Pacific coast. The family Sciaenidae contains about 70 genera anylodon species and is an important world fish resource Nelson,this family being represented in Anvylodon Atlantic waters by about 21 genera and 57 species, of which more than 30 are found along the Brazilian coast.


This paper is contribution n. From a commercial point of view, M. In a study of the meristic and morphometric traits of M. Pomacentridae as determined by mitochondrial ribosomal DNA data. Confused by a class within a class or an order within an order? 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.

Mol Phylogenet Evol 13 3: Wikisource 0 entries edit.

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. Pescadillo del Rey Spanish. Twenty-five sites of the bp of the cytochrome ancyodon gene and 11 of the bp macrodo the 16S rRNA gene are diagnostic in terms of separating the tropical and subtropical Macrodon groups Figures 2 and 3nucleotide divergence being of the same magnitude as the values detected for intrageneric comparisons in Perciformes.

In the phylogenetic trees Figures 4 and 5the populations cannot be separated because individuals belonging to very distant geographical regions group together. These values are similar to results obtained in several other groups of fish Farias et al.
