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.

The forests in these regions have been seriously damaged. This contribution illustrates the methodology adopted in the emergency phase to estimate forest damages caused by Vaia storm, both in terms of damaged forest areas and growing stock volume of fallen trees. 494 Municipalities registered forest damages caused by Vaia, destroyed or intensely damaged forest stands amounted to about 42

Habitat loss and fragmentation have serious consequences for long-term population persistence, thus we investigated the effects of these processes on jaguars (Panthera onca) across the species' distribution range. We employed theoretical simulations of population dynamics, making use of real and hypothetical landscapes to understand how landscape patterning affects the long-term persistence of species, and investigated the isolated and synergistic effects of habitat loss and fragmentation. Jaguar persistence probability was related both to the amount and pattern of landscape subdivision, but with a strong tolerance for habitat loss because the amount habitat could be between 230 to 5841 km 2. In contrast, the persistence probability of smaller jaguar populations decreased dramatically in fragmented landscapes, indicating that fragmentation is a greater threat to jaguar long-term viability than habitat loss. Only two of the 28 populations included in our study were deemed viable in the long-term. Given the increase in habitat fragmentation and the current threat status of the jaguar, we discuss the best strategies for their conservation.

Felid species have intrinsic ecological traits that make them particularly susceptible to the threats of habitat loss and fragmentation. We collate current knowledge of the effects of habitat loss and fragmentation on felids, describing trends, investigating the allocation of research effort and identifying knowledge gaps. We searched the scientific literature and categorized articles according to conceptual and methodological approaches. We reviewed 162 articles and observed that scientific knowledge is unevenly distributed among topics and species. Habitat suitability and patch–landscape configuration are the most studied topics. The allocation of research effort is unrelated to variables that describe conservation priorities, such as threat status and habitat availability within a species’ range, but it is related to body size, suggesting that charismatic attributes influence the choice of target species. Countries with less research effort are also those with less economic development, and thus North America and Europe are the centres of knowledge generation of reviewed studies. The responses of sixteen felid species to habitat loss and fragmentation remain unknown. Of these the Andean mountain cat Leopardus jacobita, the Bornean bay cat Pardofelis badia, the flat-headed cat Prionailurus planiceps and the fishing cat Prionailurus viverrinus most urgently require research because they are threatened with extinction. We recommend the use of theoretical approaches, through modelling exercises, as a first step to address the lack of information about the effects of habitat loss and fragmentation on felids, especially for those species for which there are large knowledge gaps.

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal‐central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation‐related research. There are no copyright restrictions.
