TL;DR: 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.
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 Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae).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 (peer-reviewed 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 large-scale 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.

TL;DR: This work states that introduced species become invasive when they disrupt ecosystem processes by negatively affecting native species through direct, indirect or apparent competition, predation, habitat modification, and alteration of nutrient and water cycles.
Abstract: Biodiversity loss is currently one of the most important societal concerns worldwide, and it is caused mainly by habitat loss and fragmentation, biological invasion, and climate change (Vitousek et al. 1996, Newbold et al. 2015, Bellard et al. 2016). Introduced species can have positive effects on human well-being, especially when used for livelihoods benefits (Shackleton et al. 2019). However, introduced species become invasive when they disrupt ecosystem processes by negatively affecting native species through direct, indirect or apparent competition, predation, habitat modification, and alteration of nutrient and water cycles (Long 2003, Mooney et al. 2005, Clout and Rusell 2007, Bellard et al. 2016).

TL;DR: The results highlight the Terminos-Centla wetlands as one of the most important systems of Mesoamerica for the medium-sized and large mammals and and underlines the urgent need to develop conservation strategies for the area.
Abstract: Wetlands are one of the most productive ecosystems in the world. However, they have received little attention in the tropics. Biodiversity data from the Terminos-Centla wetlands is limited despite the conservation efforts to protect these wetlands. In this study we list the medium-szied and large mammals from 8 sites within the Terminos-Centla wetlands. We recorded 30 native and 1 introduced species, representing 9 orders, 14 families, and 27 genera. Four of the recorded species are Threatened, 9 Endangered, and 1 under special protection under Mexican legislation. Compared with other sites of southeastern Mexico, the area of the Terminos-Centla wetlands has a many more species. Our results highlight the Terminos-Centla wetlands as one of the most important systems of Mesoamerica for the medium-sized and large mammals and and underlines the urgent need to develop conservation strategies for the area.

TL;DR: In this article, the authors used camera traps to verify the functionality of the Calakmul and Laguna de Terminos jaguar corridor and found the presence of jaguars in three of the four sections.
Abstract: The fragmentation of jaguar Panthera onca populations as a result of habitat loss is considered to be one of the main challenges for the conservation of the species. Corridors have been proposed as a means of maintaining connectivity and the long-term viability of jaguar populations. The corridor that connects the jaguar conservation units of Calakmul and Laguna de Terminos in Mexico has been considered to be a link for the movement of individuals between these units but its functionality had yet to be verified. During 2012–2014 we divided the corridor into four sections, where we used camera traps to verify the corridor's functionality. We obtained 106 photographs of jaguars, proving the presence of jaguars (including resident jaguars and females) in three of the corridor sections. We did not record any individuals in more than one section of the corridor. The presence of several resident jaguars and females throughout the corridor suggests that portions of the corridor should be incorporated into the Calakmul and Laguna de Terminos jaguar conservation units. Nevertheless, to confirm that the corridor is fully functional it is necessary to obtain evidence of movement of jaguars among the various sections of the corridor. Our results suggest that the area should be included in regional conservation strategies.

TL;DR: A detailed account of the original range of coyotes and their subsequent expansion provides the core description of a large scale ecological experiment that can help to better understand the predator-prey interactions, as well as evolution through hybridization.
Abstract: The geographic distribution of coyotes (Canis latrans) has dramatically expanded since 1900, spreading across much of North America in a period when most other mammal species have been declining. Although this considerable expansion has been well documented at the state/provincial scale, continent-wide descriptions of coyote spread have portrayed conflicting distributions for coyotes prior to the 1900s, with popularly referenced anecdotal accounts showing them restricted to the great plains, and more obscure, but data-rich accounts suggesting they ranged across the arid west. To provide a scientifically credible map of the coyote’s historical range (10,000–300 BP) and describe their range expansion from 1900 to 2016, we synthesized archaeological and fossil records, museum specimens, peer-reviewed reports, and records from wildlife management agencies. Museum specimens confirm that coyotes have been present in the arid west and California throughout the Holocene, well before European colonization. Their range in the late 1800s was undistinguishable from earlier periods, and matched the distribution of non-forest habitat in the region. Coyote expansion began around 1900 as they moved north into taiga forests, east into deciduous forests, west into costal temperate rain forests, and south into tropical rainforests. Forest fragmentation and the extirpation of larger predators probably enabled these expansions. In addition, hybridization with wolves (C. lupus, C. lycaon, and/or C. rufus) and/or domestic dogs has been documented in the east, and suspected in the south. Our detailed account of the original range of coyotes and their subsequent expansion provides the core description of a large scale ecological experiment that can help us better understand the predator-prey interactions, as well as evolution through hybridization.

TL;DR: An updated and annotated checklist of mammals occurring in Brazil is presented, finding that 15 new species were described since the last national compilation (published in 2017), which associated to new records to the country and synonimizations resulted in an increment of 30 species.
Abstract: An updated and annotated checklist of mammals occurring in Brazil is presented. A total of 751 native species, distributed in 249 genera, 51 families and 11 orders were recorded to the country. The Brazilian mammalian fauna shows an elevated rate of endemism (30%; 223 species). Among the species evaluated by IUCN (668 species; 90%), a total of 80 (10.6% of total mammalian fauna) are Threatened, 28 (3.9%) are considered as Near Threatened, two species (0.3%) are presumable Extinct, 96 (12.8%) are considered with Deficient Data for conservation and 462 (61.6%) are considered as Least Concern. Fifteen new species were described since the last national compilation (published in 2017), which associated to new records to the country and synonimizations resulted in an increment of 30 species. Eight non-native species were introduced to the country, including the recently established Asiatic cervids Rusa unicolor (sambar) and Axis axis (chital). Seven native species (five primates and two hystricomorph rodents) have been translocated from their areas of natural occurrence to other areas inside the country.
