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 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set 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 southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard 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 data sets of Neotropical Series that 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 data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data.
foram listadas como as principais ameaças para os mamíferos da Bahia. Trinta e três das 45 espécies ameaçadas ou 'Quase Ameaçadas' tiveram registros em 21 Unidades de Conservação (UC) de proteção integral, localizadas inteira ou parcialmente na Bahia, e 32 das 45 espécies são cobertas por Planos de Ação Nacional (PAN). A lista de mamíferos ameaçados de extinção na Bahia inclui percentual elevado de carnívoros, mamíferos aquáticos, primatas e ungulados, seguindo o padrão observado em listas vermelhas. O alto número de espécies 'Dados Insuficientes' e a concentração de esforços de pesquisa em regiões restritas do estado são alarmantes e sugerem ausência de planejamento e baixa aplicação de recursos para descrever a biodiversidade, resultando em um conhecimento limitado sobre as populações de mamíferos e suas distribuições geográficas. A Bahia ocupa uma posição de destaque para a conservação de alguns taxa cuja distribuição é total ou majoritariamente incluída no estado. Os biomas Caatinga, Cerrado e Marinho carecem de UC de proteção integral para representar sua mastofauna característica. A publicação da lista de mamíferos ameaçados de extinção, investimentos para a criação e proteção efetiva de UC existentes e outras ações previstas em PAN são instrumentos complementares que devem ser fomentados por instituições governamentais e não-governamentais no intuito de proteger a rica diversidade de mamíferos da Bahia.

ABSTRACT-FIRST EVALUATION OF MAMMALS CONSERVATION STATUS IN BAHIA, BRAZIL Endangered species lists identify real and potential taxa extinction risks at global and regional scales, supporting decision-making processes and public policy. The construction of the first list of threatened species in Bahia state started in 2013. This paper describes the evaluation of conservation status of mammals in Bahia and its main results. The list was built in three phases: (1) preparatory, (2) evaluation and (3) final (validation). One species was considered regionally extinct, 41 were included in categories of threat ('Critically Endangered', 'Endangered' or 'Vulnerable') and four were considered 'Near Threatened'. Moreover, 51 species were classified as 'Data Deficient'. Habitat loss and fragmentation, hunting and roadkill were listed as the main threats for mammals in Bahia state. Thirty three out of 45 threatened or 'Near Threatened' species were recorded in 21 strictly protected areas (PA), completely or partially located in Bahia, and 32 of the 45 species are included in National Action Plans (PAN). The list of threatened mammals of Bahia includes a high percentage of carnivores, aquatic mammals, primates and ungulates, following the pattern of red lists. The high number of 'Data Deficient' species and research effort concentration in relatively small regions along the state are alarming and suggest the absence of planning and insufficient resource destination for biodiversity description, resulting in a limited knowledge on mammal populatio...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
