    Drosophila evolution over space and time (DEST):A new population genomics resource

    Drosophila melanogaster is a leading model in population genetics and genomics, and a growing number of whole-genome datasets from natural populations of this species have been published over the last years. A major challenge is the integration of disparate datasets, often generated using different sequencing technologies and bioinformatic pipelines, which hampers our ability to address questions about the evolution of this species. Here we address these issues by developing a bioinformatics pipeline that maps pooled sequencing (Pool-Seq) reads from D. melanogaster to a hologenome consisting of fly and symbiont genomes and estimates allele frequencies using either a heuristic (PoolSNP) or a probabilistic variant caller (SNAPE-pooled). We use this pipeline to generate the largest data repository of genomic data available for D. melanogaster to date, encompassing 271 previously published and unpublished population samples from over 100 locations in > 20 countries on four continents. Several of these locations have been sampled at different seasons across multiple years. This dataset, which we call Drosophila Evolution over Space and Time (DEST), is coupled with sampling and environmental meta-data. A web-based genome browser and web portal provide easy access to the SNP dataset. We further provide guidelines on how to use Pool-Seq data for model-based demographic inference. Our aim is to provide this scalable platform as a community resource which can be easily extended via future efforts for an even more extensive cosmopolitan dataset. Our resource will enable population geneticists to analyze spatio-temporal genetic patterns and evolutionary dynamics of D. melanogaster populations in unprecedented detail.DrosEU is funded by a Special Topic Networks (STN) grant from the European Society for Evolutionary Biology (ESEB).

    Brazilian Consensus on Photoprotection

    Get PDF
    Brazil is a country of continental dimensions with a large heterogeneity of climates and massive mixing of the population. Almost the entire national territory is located between the Equator and the Tropic of Capricorn, and the Earth axial tilt to the south certainly makes Brazil one of the countries of the world with greater extent of land in proximity to the sun. The Brazilian coastline, where most of its population lives, is more than 8,500 km long. Due to geographic characteristics and cultural trends, Brazilians are among the peoples with the highest annual exposure to the sun. Epidemiological data show a continuing increase in the incidence of nonmelanoma and melanoma skin cancers. Photoprotection can be understood as a set of measures aimed at reducing sun exposure and at preventing the development of acute and chronic actinic damage. Due to the peculiarities of Brazilian territory and culture, it would not be advisable to replicate the concepts of photoprotection from other developed countries, places with completely different climates and populations. Thus the Brazilian Society of Dermatology has developed the Brazilian Consensus on Photoprotection, the first official document on photoprotection developed in Brazil for Brazilians, with recommendations on matters involving photoprotection

    Discutindo o currículo "por dentro": contribuições da pesquisa etnográfica

    Este artigo discute algumas contribuições que a pesquisa etnográfica pode dar à compreensão dos processos de reformulação curricular que têm sido levados a efeito nos diferentes sistemas de ensino. O potencial desse tipo de pesquisa é aqui discutido e apresentado a partir da análise dos resultados obtidos em estudos realizados como parte das atividades do Projeto Recriando Histórias de Pinhais, desenvolvido no âmbito do acordo de Cooperação Técnica, firmado entre a Universidade Federal do Paraná e a Prefeitura Municipal de Pinhais, a partir de 1997. Orientado principalmente para os saberes a serem ensinados em História, nas séries iniciais do ensino fundamental, as investigações mostraram formas pelas quais as professoras elaboraram e articularam saberes e práticas no seu trabalho cotidiano, permitindo explicitar alguns princípios que podem contribuir para o debate sobre a formulação e avaliação de propostas curriculares

    Memorial acadêmico para Professor Titular

    No cumprimento do requisito parcial para obtenção do título de Professora Titular do Departamento de Teoria e Prática da Educação da UFPR, elaboro este Memorial Descritivo para que seja julgado por banca de professores titulares, cujos nomes e currículos foram aprovados no âmbito de meu Departamento e Setor. Percorrer novamente a trajetória construída na vida acadêmica, agora de um gole só para alcançar o termo da narrativa, identificando o fluxo do “sangue quando fervia” e selecionar alguns elementos fractais que logrem expressar o paradigma político-epistemológico-afetivo ao qual me vinculo é uma viagem emocionante, que encanta e dói, veste e desnuda
