“…Contudo, algumas espécies com ocorrência confirmada para a Caatinga do estado não foram registradas aqui. Sylvilagus brasilensis ocorre em uma área a aproximadamente 35 km a sudeste de Caiçara do Norte (Dantas et al 2016). Já Lontra longicaudis, espécie semi-aquática, ocorre na faixa de transição da Caatinga com a Floresta Atlântica (Rosas- Ribeiro et al 2017), região não amostrada neste trabalho.…”

“…Diferente dos estados vizinhos, o Rio Grande do Norte não foi visitado por expedições históricas, que realizadas a partir do século XVII impulsionaram o conhecimento sobre mamíferos no restante do nordeste do Brasil (Feijó & Langguth 2013). Para mamíferos de médio e grande porte os trabalhos no estado são relativamente recentes e representados basicamente por inventários paleontológicos (Araújo-Júnior & Porpino 2011) e atualizações de distribuição e primeiros registros de ocorrência (Ferreira et al 2009;Dantas et al 2016;Marinho et al 2017;Rosas-Ribeiro et al 2017). Ainda mais escassos são os trabalhos sobre a ecologia de espécies, até o momento restritos a Sapajus libidinosus (Ferreira et al 2010;Emidio & Ferreira 2012) e Leopardus tigrinus (Marinho et al 2018a;.…”

RESUMO. Mamíferos de médio e grande porte são especialmente afetados pela caça e perda de habitat, ao mesmo tempo que desempenham importantes funções no ecossistema. O conhecimento sobre esse grupo na Caatinga, a floresta tropical sazonalmente seca do nordeste do Brasil, contudo, ainda é escasso. Neste trabalho realizamos o primeiro levantamento sistemático de mamíferos de médio e grande porte no estado do Rio Grande do Norte, através de armadilhamento fotográfico em 188 pontos distribuídos em 10 áreas prioritárias para a conservação da biodiversidade da Caatinga. Com um esforço amostral de 7271 câmeras-dias, obtivemos 1607 registros de 14 espécies nativas, distribuídas em seis ordens e 10 famílias: oito espécies da ordem Carnivora, duas espécies da ordem Cingulata, e uma espécie para cada uma das demais ordens (Artiodactyla, Didelphimorphia, Pilosa e Primates). A riqueza encontrada representa 31% das 45 espécies de mamíferos de médio e grande porte que ocorrem na Caatinga, e 50% das espécies deste grupo registradas no domínio da Caatinga ao norte do Rio São Francisco, ampliando significativamente o conhecimento sobre o grupo na região. Entre as espécies registradas estão três felinos ameaçados de extinção, incluindo um grande predador de topo (Leopardus tigrinus, Herpailurus yagouaroundi e Puma concolor). O baixo número de registros de algumas espécies e a ausência de outras indicam o estado crítico da mastofauna do estado e sugerem a importância e urgência do estabelecimento de novas unidades de conservação na Caatinga do Rio Grande do Norte.ABSTRACT. Medium to large-sized mammals from the Caatinga of the Rio Grande do Norte, in Northeast Brazil. Medium to large-sized mammals are the most affected by habitat loss and hunting, while at the same time playing important roles in the ecosystem. The knowledge about this group in the Caatinga, the dry tropical forest of northeastern Brazil, however, is still scarce. In this study, we carried out the first systematic survey of medium to large-sized mammals in the Rio Grande do Norte state, with camera traps installed in 188 points distributed in 10 priority areas for the conservation of the Caatinga biodiversity. With a sampling effort of 7271 camera-days, we obtained 1607 records of 14 native medium to large-sized mammals, distributed in six orders and 10 families: eight species of the order Carnivora, two species of the order Cingulata, and one species for each of the other orders (Artiodactyla, Didelphimorphia, Pilosa e Primates). The richness recorded represents a third of the 45 large and medium-sized mammal species found in the Caatinga, and half of the large and medium-sized mammal species recorded in northern Caatinga dominium, significantly increasing the knowledge about the group in the region. Among the recorded species are three threatened felids, including a large top predator (Leopardus tigrinus, Herpailurus yagouaroundi, and Puma concolor). The low number of records of some

“…The state of Rio Grande do Norte presents a shortage of mammalogical studies, despite recent records of some species (e.g. Dantas et al 2015;Marinho et al 2017) and a single systematic survey (Marinho et al 2018). Thus, we herein present the first record of the collared peccary specimens in Rio Grande do Norte state, more precisely in a Caatinga-Atlantic Forest ecotone area.…”

The collared peccary Pecari tajacu (Artiodactyla, Tayassuidae) is widely distributed and included in the Least Concern (LC) category by the IUCN assessment. However, threats such as hunting and habitat loss have extinguished some of its populations in Brazil. Additionally, much of its current occupation area remains unknown, especially in northeastern Brazil. We herein present the first record of the collared peccary in a Caatinga-Atlantic Forest ecotone in the state of Rio Grande do Norte, northeastern Brazil. This record in a poorly sampled region represents the presence of this species in the most northeastern part of the country and extends its confirmed records for more than 200 km.

“…(Reis et al, 2011). Although it has been commonly recorded at wildlife inventories and most of tropical forest sites are included into its occurrence area, its ecology has unfortunately been neglected (Silva Júnior et al, 2005;Dantas et al, 2016;Andrade & Hernández, 2017). Thus, it is fundamental to understand the behavioral adjustments of these herbivores to environmental changes.…”

On this study, we used camera traps in a Semi deciduous Seasonal Forest, northeast of Brazil, to estimate the frequencies of occurrence of two Neotropical herbivorous mammals: the spotted paca (Cuniculus paca) and the tapeti (Sylvilagus brasiliensis), analyzing their seasonal variations of spatial distribution. We also characterized the activity pattern of the species and their seasonal variation. The herbivorous frequencies of occurrence were constant during all the seasons. In general, both species were mostly active at night. However, between the rainy and dry season, we identified differences in spotted paca activity peaks. Here we present one of the first studies on the tapeti, whose ecology is understudied. Our results also show a general view of the spotted paca and tapeti behavior strategies to seasonal variations. Due to the scarce food resource in the dry season, possibly these herbivorous need to search for different kinds of food available IFS around.
