Chapada dos Veadeiros National Park is one of the most important protected areas of the Brazilian Cerrado and is inhabited by diverse species, but the area has seldom been studied. From 2006 to 2008, we studied the impact of roads on wild vertebrates by recording roadkill on the two main roads located in the vicinity of the park. Of 824 killed vertebrates belonging to 138 species that were recorded, the species that were found most often in each vertebrate group were the Schneider's toad (Rhinella schneideri), the grassland sparrow (Ammodramus humeralis), the yellow-toothed cavy (Galea flavidens), and the marbled lancehead (Bothrops marmoratus). The roadkill rate was 0.096 animals km -1. Vertebrate mortality was significantly higher during the wet season. There is a significant relationship between habitat structure and the vertebrates that were found as roadkill: amphibians are associated with nearby forest and paved roads, birds with nearby pastures, reptiles with nearby grassland, and mammals with unpaved roads. Action should be taken such as highway fencing in combination with safe crossing opportunities for wildlife in order to decrease the number of animals killed on the roads.

Chapada dos Veadeiros National Park (CVNP) in central Brazil is one of the most important protected areas of Brazilian Cerrado yet the diversity that this park harbors remains unknown for many taxa. From 2006 to 2009, we studied the snake assemblage of CVNP to determine the species composition, abundance, seasonal and daily activity patterns, morphology, and habitat use. We documented 47 snake species from seven families within CVNP, with the most common species being Bothrops marmoratus, Oxyrhopus trigeminus, Crotalus durissus and Bothrops moojeni. The incidence of snakes was highly seasonal and appeared to be associated mainly with rainfall. Daily activity patterns revealed that the majority of snakes are strictly diurnal, whereas others are nocturnal or active during both periods. Species richness estimators suggest that more snake species than the 47 we documented likely occur within CVNP, indicating that it harbors one of the richest snake faunas

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.

Resumo As atividades humanas vêm alterando o meio ambiente e contribuindo para a aceleração das mudanças climáticas (MC). Diante disso, é necessária a compreensão de como novas percepções podem resultar em ações em prol do ambiente, além do papel da educação ambiental nessa equação. Logo, foram aplicados 1526 questionários objetivando compreender a percepção de universitários sobre os impactos das MC em diferentes setores da sociedade e extratos sociais, além de outras crenças pessoais. Observou-se a necessidade de maior abordagem de conhecimentos ambientais, com a inserção desses temas nos currículos de todos os níveis de ensino, em consonância com a lei 9795/99. Além disso, o limitado conhecimento sobre a ligação entre informação, percepção e ações de enfrentamento às mudanças no clima, indica a necessidade de desenvolvimento de mais pesquisas que possam explorar como a melhor qualidade de ensino na educação ambiental e climática pode auxiliar nas percepções e ações em prol das políticas públicas de adaptação e mitigação.

Mimicry is an excellent example of how natural selection can act on color, morphology, and behavior of species. Herein we assess predation rates on coral snake mimics in Central Brazil, a region with many mimics but only a single model, to answer the following questions: (i) Do predators avoid attacking coral snake mimics? (ii) Does the degree to which mimics resemble their venomous model affect the frequency of predator attacks? (iii) Do predators attack different body regions in mimics with different color patterns? Our experiment was conducted in the Chapada dos Veadeiros National Park, in the municipality of Alto Paraíso de Goiás, state of Goiás, Brazil. To evaluate predation rates on the different mimic patterns, we made 2,400 clay snake replicas using pre-colored nontoxic plasticine and distributed them in open savanna landscapes within the park. A total of 164 (6.83%) replicas were attacked by predators of snakes. Among these attacks, 121 were attacks by birds, and 43 were attacks by carnivorous mammals. Logistic regression and Fisher’s exact test indicated that replicas with red, white, and black coloration are less likely to be attacked than were grey replicas, and coral snake replicas were attacked more often at the “head” end. Also, the greater the similarity to the pattern of venomous coral snakes, the rarer the attack on the replica. Our study underscores the strong selective force that protects coral snake mimics from predators. Our findings reinforce resemblance to the model as an extremely effective strategy in a complex natural system with only one model and numerous mimics.

Os estudos etnobotânicos e etnofarmacológicos existentes possuem como consenso que o bioma Cerrado é detentor de uma das maiores diversidades biológicas de espécies, principalmente quando se trata de plantas com potencial medicinal. Pesquisas sobre a flora medicinal do Cerrado tem sido realizadas para todos os Estados abrangidos pelo bioma, e considerando o alto grau de endemismo que cada região possui em relação a certas espécies, estas regiões apresentarão uma flora medicinal com espécies comuns a outras e com espécies particulares. A metodologia utilizada neste estudo foi a revisão bibliográfica e de análise de dados, a qual se mostrou mais adequada para este tipo de pesquisa, porque visa identificar a produção quantitativa e qualitativa do tema em questão nos últimos vinte anos. Neste estudo, foi realizado um levantamento bibliográfico de pesquisas etnobotânicos e etnofarmacológicas abordando plantas medicinais do Cerrado. Baseando-se no pressuposto de que o Cerrado é um bioma que apresenta um valor inestimável devido à sua biodiversidade, observa-se a necessidade de pesquisas e valorização do conhecimento em torno das espécies vegetais presentes nesse cenário. Outro aspecto que merece ser destacado, é que o medicamento fitoterápico tradicional é aquele elaborado a partir de planta medicinal de uso embasado na tradição popular, sem evidências conhecidas de risco à saúde do usuário, cuja eficácia é validada através de levantamentos etnofarmacológicos e de utilização, documentação científica ou publicações indexadas.
