Description
Summary:The introduction of exotic species is currently the second largest cause of extinction. In this sense the domestic dog (Canis lupus familiaris) stands out, given its wide distribution and adaptive plasticity. Understanding the dynamics of dog occurrence in natural areas is of major importance in order to understand the impacts on native fauna. In this work, we aimed to carry out an updated survey of the presence of dogs in the Area of Relevant Ecological Interest Mata of Santa Genebra, focusing on the number of individuals, their periods and areas of greatest activity. Sampling was carried out using camera-traps on nine different trails in the area, with a sampling effort of 2754 camera-days. A total of 316 mammal records were obtained of which 28% documented the presence of dogs. The results point to greater activity of dogs in areas of extensive trails, clearings and forest edge, in addition to the preference for night periods and rainy season. The results were compared with the periods of activity of native non-flying mammals of the area, obtaining a similar occupation of places and periods, both of domestic dogs and native fauna. Finally, proposals were presented to mitigate this problem in the area. A introdução de espécies exóticas é, hoje, a segunda maior causa de extinção de espécies. Neste sentido, o cão doméstico (Canis lupus familiaris) se destaca, visto sua ampla distribuição e plasticidade adaptativa. Entender a dinâmica de ocorrência de cães em áreas naturais é de suma importância, a fim de compreender os impactos para a fauna nativa. Neste trabalho, visou-se realizar um levantamento atualizado da presença de cães na Área de Relevante Interesse Ecológico Mata de Santa Genebra, com enfoque no número de indivíduos, seus períodos e áreas de maior atividade. A amostragem foi realizada com uso de armadilhas fotográficas em nove trilhas distintas da área, com esforço amostral de 2754 câmeras-dia. Foram obtidos 316 registros de mamíferos, dos quais 28% documentaram a presença de cães. Os resultados ...
