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.

Roadkill is widely recognized as one of the primary negative effects of roads on many wildlife species and also has socioeconomic impacts when they result in accidents. A comprehensive dataset of roadkill locations is essential to evaluate the factors contributing to roadkill risk and to enhance our comprehension of its impact on wildlife populations and socioeconomic dimensions. We undertook a compilation of roadkill records, encompassing both published and unpublished data gathered from road surveys or opportunistic sources. GLOBAL ROADKILL DATA includes 208,570 roadkill records of terrestrial vertebrates from 54 countries across six continents, encompassing data collected between 1971 and 2024. This dataset serves to minimise the collection of redundant data and acts as a valuable resource for local and macro scale analysis regarding rates of roadkill, road- and landscape-related features associated with risk of roadkill, vulnerability of species to road traffic, and populations at risk of local extinction. The objective of this dataset is to promote scientific progress in infrastructure ecology and terrestrial vertebrate conservation while limiting the socio-economic costs.

Anaplasmataceae agents are obligatory intracellular Gram-negative α-proteobacteria that are transmitted mostly by arthropod vectors. Although mammals of the Superorder Xenarthra (sloths, anteaters, and armadillos) have been implicated as reservoirs for several zoonotic agents, only few studies have sought to detect Anaplasmataceae agents in this group of mammals. This study aimed to investigate the occurrence and genetic diversity ofAnaplasmaspp. andEhrlichiaspp. in blood and spleen samples of free-living Xenarthra from four different states in Brazil (São Paulo, Mato Grosso do Sul, Rondônia, and Pará). Nested and conventional PCR screening assays were performed to detect therrsanddsbgenes ofAnaplasmaspp. andEhrlichiaspp., respectively. The assays were positive in 27.57% (91/330) of theAnaplasmaspp. and 24.54% (81/330) of theEhrlichiaspp. Of the 91 positiveAnaplasmaspp. samples, 56.04% were positive in a conventional PCR assay targeting the 23S–5S intergenic region. Phylogenetic and distance analyses based on therrsgene allocatedAnaplasmasequences from sloths captured in Rondônia and Pará states in a single clade, which was closely related to theA. marginale,A. ovis,andA. capraclades. The sequences detected in southern anteaters from São Paulo were allocated in a clade closely related to sequences ofAnaplasmaspp. detected inNasua nasua,Leopardus pardalis, andCerdocyon thousin Brazil. These sequences were positioned close toA. odocoileisequences. Genotype analysis corroborated previous findings and demonstrated the circulation of two distinctAnaplasmagenotypes in animals from north and southeast Brazil. The first genotype was new. The second was previously detected inN. nasuain Mato Grosso do Sul state. The intergenic region analyses also demonstrated two distinct genotypes ofAnaplasma. The sequences detected in Xenarthra from Pará and Rondônia states were closely related to those inA. marginale,A. ovis,andA. capra.Anaplasmaspp. sequences detected in Xenarthra from São Paulo and were allocated close to those inA. phagocytophilum. The analyses based on thedsbgene grouped theEhrlichiaspp. sequences with sequences ofE. canis(São Paulo, Mato Grosso do Sul, and Pará) andE. minasensis(Rondônia and Pará). The data indicate the occurrence ofE. canisandE. minasensisand two possible newCandidatusspecies ofAnaplasmaspp. in free-living mammals of the Superorder Xenarthra in Brazil.
