Validity of electrophoresis in identifying fish populations structures. A stem-based total clade Teleostei has been accepted for this work. It is important to point out that the average taxonomic distance is inversely proportional to the identity coefficient, and that when one increases, the other one decreases proportionally.

Highly polymorphic AFLP markers were applied to analyse the phylogenetic relationships of seven species from three sections within genus Araucaria Araucariaceae with cladistic and phenetic approaches. The objectives of the study were to compare the intrageneric relationships within Araucaria assessed by AFLP markers with the classification according to chloroplast DNA sequences and morphological characters. The results of the principal coordinate analysis revealed three distinct groups: 1 A.

In the cladistic and phenetic analyses, phylogenetic trees were subdivided into two sister clades, one comprising the samples from section Eutacta, the other one was divided again into two sister clades corresponding to sections Araucaria and Bunya. These results are congruent with a previous phylogenetic study of the family Araucariaceae based on rbcL sequences and with the classification of genus Araucaria based on morphological characters. Both rbcL sequence data and AFLP analyses do not support section Bunya as one of the oldest sections within genus Araucaria, as suggested by the fossil record.

The genus Bagre is also separated from these two genera, but is closer to Ariopsis. According to Betancur, the restriction to freshwater environments of some of the studied species involves at least three events of secondary invasion of neotropical ariines, and implies a reversal to the primitive conditions of the Otophysi.

Lotic communities have conditions that are rather harsh for typical plants.
