Systematics, Evolution and Conservation of Eastern Brazilian Mammals

Abstract

Eastern Brazil possess one of richest endemic mammal faunas of South America. It is also the most economically developed region of Brazil, with severe consequences to natural ecosystems. MY study of the diversity of the mammal fauna of this region must contemplate systematic and evolutionary studies, as well as those devoted to conservation. The need for systematic and evolutionary studies is explained by the extensive gaps in our knowledge of the mammalian taxa of the region, their geographic distributions, their evolutionary history viz a viz that of the ecosystems they inhabit. We believe that most of the knowledge produced by systematic studies have a decisive impact on decisions made to preserve the mammalian fauna and the ecosystems in which they occur, beginning with a much more precise listing and quantification of the diversity to be preserved, and also the definition of geographic areas where significant fractions of this diversity are located. Besides this, Brazil do not presently have a sustained program of population monitoring for important mammal species. This results in the fact that National Parks and Biological Reserves are created in the country without any means for the responsible Federal and State institutions to know if the reserves are being effective in the conservation of the mammalian fauna in particular and biotas in general. Thus, this project has two main goals: a) recognize, describe, map mammalian taxa in the region encompassed by the project, as well as to propose hypothesis about the evolution of eastern Brazilian mammal faunas; and b) elaborate a low cost protocol for the monitoring of selected key species of mammals for very long periods of time, to be applied by institutions responsible for the maintenance of biological reserves in Brazil. The systematic part of this project will be approached through the collection of specimens and their study under anatomical, cytogenetic and molecular studies, with ample consultation to existing collections of mammals. The population monitoring part of this project will be developed in a single study site, with the study of selected target species, using several methods (capture-marking-recapture, mapping of tracks and feces, determination of reproductive hormonal levels in feces). Besides the publication of articles relative to all particular findings that will occur during the development of the project, we intend to publish a final synthetic work with the same name of the project, which will include complete systematic accounts and the population monitoring protocol.
