    Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

    Foi realizada revisĂŁo bibliogrĂĄfica analĂ­tica com o objetivo de quantificar o impacto dos efeitos da ocupação sobre a mortalidade de trabalhadores em suas implicaçÔes sobre o setor saĂșde. As repercussĂ”es sobre a mortalidade de trabalhadores sĂŁo medidas atravĂ©s das mortes diretamente relacionadas com o trabalho (acidentes do trabalho fatais e intoxicaçÔes fatais) e das indiretamente relacionadas. Partindo das grandes causas de morte entre adultos - doenças cardiovasculares, cĂąncer e mortes violentas - e explorando as informaçÔes obtidas em estudos epidemiolĂłgicos realizados em outros paĂ­ses, estimou-se a força da contribuição da ocupação sobre a mortalidade. O peso e a complexidade das repercussĂ”es sobre o setor saĂșde pressupĂ”em um desempenho mais ativo na definição de polĂ­ticas e responsabilidades, e na organização de açÔes destinadas a identificar, reduzir ou eliminar a participação dos riscos ocupacionais nas grandes causas de doença e morte.<br>An attempt to estimate the impact of occupation on worker's health was made as part of the rationale for the progressive integration of Occupational Health into the Health Sector. In this second study, based on a critical review of the literature, the repercussions on mortality are discussed on this basis analysis of the Brazilian data on deaths directly related to occupation (fatal occupational accidents and acute poisonings), as well as on those indirectly so related. The analysis of the major causes of adult deaths - cardiovascular diseases, cancer and violent deaths - compared with the proportion of "work-relatedness" according to several epidemiologic studies carried out in developed countries, make possible an estimation of the influence of the contribution of occupation on mortality. The size of this contribution is the main argument for an active involvement of the health sector in Occupational Health issues, because of the heavy toll in terms of adult morbidity and mortality exacted on industrialized societies
