Inventário da ictiofauna do alto rio Paraíba do Sul e caracterização molecular das espécies encontradas

The state of São Paulo has four main drainages: Paraná river, Paraíba do Sul river, Ribeira do Iguape river and coastal rivers. The Paraíba do Sul river is born in Sao Paulo and drains an important range of land east of the state. Its ichthyofauna has some similarities and many differences from the continental and coastal drainages which highlights the importance of this study. Surveys conducted in the ichthyofauna of this basin, as in other large river basins in Brazil, is still incomplete. Moreover, there is no consensus about the taxonomic status of many species listed in these surveys. Considering the promising use of DNA barcode as a global system for species identification, the present study is aimed to establishing an inventory of the ichthyofauna of the São Paulo portion of the river Paraíba do Sul and simultaneously build a DNA barcode reference sequence library for fish found. Were obtained and analyzed 354 sequences of the gene cytochrome oxidase c subunit I (COI) belonging to 66 species of São Paulo portion of the Paraíba do Sul river. The average K2P distance between individuals within species of this basin was 0.48%, and 9,87% between species within a genus. Five pairs of species (10 species) showed low levels of interspecific genetic divergence (<2%),but all could be correctly identified. This study showed that the fish species analyzed could be identified efficiently through the use of barcode generating data that can provide information for further studies of this fauna, besides contributing to the global initiative to characterize the species of fish in the world of a molecular point of view. Five pairs of species (10 species) showed low levels of interspecific genetic divergence (<2%), but all could be correctly identified. This study showed that the fish species analyzed could be identified efficiently through the use of barcode generating data that can provide subsidies for further studies in this fauna, as well as ...

Easy Bioinformatics Analysis (EBiAn): a package for manipulating and analysis of short biological sequences

The work of biochemists and molecular biologists often is dependent or extremely favored by a preliminary computer analysis. Thus, the development of an efficient and friendly computational tool is very important. In this work, we developed a package of programs in Javascript language which can be used online or locally. The programs depend exclusively of Web browsers and are compatible with Internet Explorer, Opera, Mozilla Firefox and Google Chrome. With the EBiAn package it is can perform the main analysis and manipulation of DNA, RNA, proteins and peptides sequences. The programs can be freely accessed and adapted or modified to generate new programs.
