| The present study used the previously defined relationships among the snail-killing species of Sepedonea as the starting point for a cladistic biogeography analysis of endemic areas in the Neotropical region. The goal of the study was to use two different data sets to test the possible monophyly of two important biomes in the region: the Amazon and the Atlantic Forest. The possible historical significance of the arid biomes was also investigated. The study used Brooks Parsimony Analysis (Primary BPA). The area groups were based on previous biogeographical classifications of the Neotropial region. The analyses showed Amazonia to be non-monophyletic whereas the Atlantic forest was found to be a natural unit. The importance of including dry areas in the... |

| The taxonomic crisis, emphasized in recent years, is marked by the lack of popularity (lack of interest in taxonomy) and financial incentives to study biodiversity. This situation, coupled with the issues involved with the necessity of knowing many yet undiscovered species, has meant that new technologies, including the use of DNA, have emerged to revitalize taxonomy. Part of the scientific community, however, has rejected the use of these innovative ideas. DNA barcoding has especially been the target of numerous criticisms regarding its application, as opposed to the use of morphology. This paper aims to highlight the inconsistency of the debate involving DNA versus morphology, since there is a proposal for the integration of traditional taxonomy and DNA... |
