ABSTRACT
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 Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae).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.

ABSTRACT
Understanding the factors that influence the presence and distribution of carnivores in human-dominated agricultural landscapes is one of the main challenges for biodiversity conservation, especially in landscapes where setting aside large protected areas is not feasible. Habitat use models of carnivore communities in rubber plantations are lacking despite the critical roles carnivores play in structuring ecosystems and the increasing expansion of rubber plantations. We investigated the habitat use of a mammalian carnivore community within a 4,200-ha rubber plantation/forest landscape in Bahia, Brazil. We placed two different brands of camera traps in a 90-site grid. We used a multispecies occupancy model to determine the probabilities of habitat use by each species and the effect of different brands of camera traps on their detection probabilities. Species showed significant differences in habitat use with domestic dogs (Canis familiaris) and crab-eating foxes (Cerdocyon thous) having higher probabilities of using rubber groves and coatis (Nasua nasua) having a higher probability of using forest. The moderate level of captures and low detection probabilities (≤ 0.1) of tayras (Eira barbara) and wildcats (Leopardus spp.) precluded a precise estimation of habitat use probabilities using the multispecies occupancy model. The different brands of camera traps had a significant effect on the detection probability of all species. Given that the carnivore community has persisted in this 70-year-old landscape, the results show the potential of rubber/forest landscapes to provide for the long-term conservation of carnivore communities in the Atlantic forest, especially in mosaics with 30-40% forest cover and guard patrolling systems. The results also provide insights for mitigating the impact of rubber production on biodiversity.

INTRODUCTION: Leptospirosis is a re-emerging infectious disease whose prevalence is often underestimated, not only in Colombia, but in most developing countries. The objective of this paper is to assess the research status of leptospirosis in Colombia in order to identify trends, knowledge gaps, and directions for future research. METHODOLOGY: With the aim of gathering all the information available on leptospirosis in the country, a web search was conducted in various indexes and databases. The search terms used were: Leptospirosis + Colombia. A total of 95 publications were found and analyzed using descriptive statistics. RESULTS: The first report of leptospirosis in the country was published in 1957. More than 60% of the published works focus on the prevalence of the disease. The Central part of the country is the area with the highest number of publications. MAT was used in 84% of the prevalence studies and humans are the most studied taxonomic group, with 45% of the publications. The highest prevalence of the disease was registered for rodents (82.7%, 62/75), followed by humans (67.9%, 53/78), pigs (67.6%, 342/506), and dogs (67.2%, 41/61). The prevalence of the disease in the country is associated with occupational factors, hygiene conditions and contact with rodents. CONCLUSION: Although leptospirosis is a prevalent disease in Colombia, the limitations of the diagnostic techniques used and the lack of a unified criteria on titers thresholds, make an accurate assessment of the prevalence of the disease in the country problematic.
