RESUMO
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non‐detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non‐governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peerreviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non‐detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio‐temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other largescale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data.
RESUMO
Abstract: The Thin-spined Porcupine (Chaetomys subspinosus) is a medium-sized and mainly arboreal rodent, endemic to the Brazilian Atlantic Forest, and threatened with extinction. Habitat loss, hunting, forest fires, agriculture and livestock are threats identified for the species. Here we raise the alert to the impact of roads on remaining populations of C. subspinosus based on roadkill records from the state of Espírito Santo, southeastern Brazil. Mortality due to roadkill is likely to impact C. subspinosus in different regions of the state, and is a widespread problem, not unique to a single location or population. The pattern of roadkills in the studied regions suggest that the species is more susceptible to collisions with vehicles in the breeding period. Additionally, concrete barriers that divide lanes on highways seens to increase the likelihood of roadkill for Thin-spined Porcupines. We recommend that roadkill should be included in the list of threats to C. subspinosus in the Espírito Santo. Mortality due to roadkill is probably relevant also for populations in the states of Bahia and Sergipe, and it should be evaluated locally. The installation of road-crossing structures for wildlife, such as arboreal overpasses, is recommended on roads crossing or close to protected areas with C. subspinosus presence in Espírito Santo and elsewhere.
Resumo: O ouriço-preto (Chaetomys subspinosus) é um roedor essencialmente arborícola, de médio porte, endêmico da Mata Atlântica brasileira. Atualmente está classificado como Vulnerável à extinção. Perda de habitat, caça, incêndios florestais, agricultura e pecuária são identificados como ameaças para a espécie. A presente comunicação alerta para o impacto de estradas sobre as populações remanescentes de C. subspinosus com base em registros de atropelamento obtidos no estado do Espírito Santo, sudeste do Brasil. Os registros aqui apresentados indicam que a morte de espécimes devido a atropelamentos afeta populações de C. subspinosus em diferentes regiões do estado, sendo um problema generalizado, não consistindo em ameaça para uma única localidade ou população. O padrão observado nas regiões estudadas sugere que a espécie é mais suscetível a atropelamentos durante o período reprodutivo. Além disso, a presença de barreiras de concreto dividindo as faixas das rodovias parece aumentar a ocorrência de atropelamentos de ouriços-pretos. Recomenda-se que o atropelamento de espécimes seja incluído entre as ameaças à conservação de C. subspinosus no Espírito Santo, podendo representar uma ameaça relevante para a espécie também nos estados da Bahia e Sergipe, o que deve ser avaliado localmente. A instalação de estruturas para transposição rodoviária pela fauna, como passagens aéreas, é recomendada para estradas que atravessam ou que estão associadas a áreas protegidas com confirmação da presença de C. subspinosus no Espírito Santo e em outros estados.
