We report 22 records of giant armadillo roadkill on Brazilian highways in the Cerrado, Pantanal and Amazon biomes illustrating that highways are a threat to this species.However, we also documented the species using underpasses, demonstrating that these structures could help to reduce the risk of roadkill for giant armadillos.

Highways limit the movement and dispersion of wild animals and contribute to their loss due to roadkills, leading to the isolation and decline of populations, increasing the risk of local extinction. The Lowland Tapir Tapirus terrestris is the largest neotropical herbivore-frugivore, and despite its wide distribution in South America it is threatened with extinction. In this study we report six roadkill events of tapirs between 2014 and 2019 in a section of a federal highway crossing the mosaic of Atlantic Forest reserves called Sooretama, one of the last tapir refuges in southeastern Brazil. The traffic in this area is heavy with inadequate speed control, while exotic fruit trees growing along the highway attract wild animals. Water drainage tunnels serve as passageways for some species, including tapirs. However, the tunnels located under the highway are not continuously maintained, reducing its effectiveness. The loss of at least one tapir per year can have serious long-term consequences for one of the last viable lowland tapir populations in the entire Atlantic Forest. Emergency measures are required to avoid vehicle-tapir collisions.
O presente trabalho traz a experiência da confecção de uma maquete geológica na escala de 1:20.000 da Serra do Caparaó, monumento geológico complexo do sudeste brasileiro, com o objetivo de ilustrar aspectos da geologia regional e definir uma rotina para construção de maquetes didáticas. Para tanto, foram utilizados dados de campo e dados espaciais em ambiente SIG para projeção do relevo sobre placas de isopor a partir de curvas de nível. Os resultados da confecção da maquete compreendem um modelo tridimensional da geologia da Serra do Caparaó e a proposta de um roteiro para confecção de maquetes didáticas. As primeiras exposições da maquete ao público proporcionaram boa interação da sociedade com as informações geológicas da região, com a introdução de conceitos de Geomorfologia, Geologia Estrutural, Cartografia e Geodiversidade.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
