    Integrating Phylogenetic and Network Approaches to Study Gene Family Evolution: The Case of the \u3ci\u3eAGAMOUS\u3c/i\u3e Family of Floral Genes

    The study of gene family evolution has benefited from the use of phylogenetic tools, which can greatly inform studies of both relationships within gene families and functional divergence. Here, we propose the use of a network-based approach that in combination with phylogenetic methods can provide additional support for models of gene family evolution. We dissect the contributions of each method to the improved understanding of relationships and functions within the well-characterized family of AGAMOUS floral development genes. The results obtained with the two methods largely agreed with one another. In particular, we show how network approaches can provide improved interpretations of branches with low support in a conventional gene tree. The network approach used here may also better reflect known and suspected patterns of functional divergence relative to phylogenetic methods. Overall, we believe that the combined use of phylogenetic and network tools provide a more robust assessment of gene family evolution

    Análise de conflitos socioambientais: o caso da comunidade rural de Rio Maior, município de Urussanga, Santa Catarina

    Get PDF
    O conflito em análise ocorre na localidade de Rio Maior, município de Urussanga,SC e aborda a mobilização de uma comunidade contra as atividades de mineração de basalto/diabásio, britagem e usinagem de asfalto conduzidos pela empresa Setep Construções, com sede em Criciúma,SC. O estudo de caso se deu com base na hipótese de que o acirramento dos conflitos socioambientais é um dos fatores determinantes para o fortalecimento das ações e para a formação de estruturas de governança ambiental local e, consequentemente, pela institucionalização da gestão ambiental municipal. Para tanto, após a revisão teórica sobre o tema, foram identificados os principais atores e condicionantes que moldaram a disputa. Por fim, com base na análise do conflito, foi elaborado um mapeamento do mesmo e identificados os principais desdobramentos que corroboram a hipótese da pesquisa
