MAMÍFEROS NEOTROPICAIS (MÉDIO E GRANDE PORTE) NO SUDOESTE GOIANO: REGISTRO DO PADRÃO DE ATIVIDADES DIÁRIAS, EM FRAGMENTOS DO CERRADO.

Abstract

The Cerrado is home to about 1/3 of the national biodiversity and in this biome the terrestrial mammal fauna is composed of approximately 230 species. As a result of different human interventions, the landscapes of the Cerrado biome have been transformed into highly fragmented landscapes. Such modifications can influence the daily activity pattern of the species which is an important aspect of an animal's life, reflecting its interactions with the environment and with other animals. Thus, this study sought to describe and analyze the activity pattern of medium and large mammals in Cerrado vegetation fragments in the Rio Verde/Goiás region. Sampling took place between 2018 and 2020, using camera traps to obtain records of the species. A total of 16 species of medium and large mammals were recorded and three species stood out in relation to the amount of records obtained: Didelphis albiventris, Dasypus novemcinctus and Sapajus libidinosus. The only diurnal species was Sapajus libidinosus and the species Cerdocyon thous was considered as catemeral, because, in this study, this canid was recorded in a 'balanced' way at different times of the day, between 04:00h and 09:00h. The present study was also able to highlight the diversity of species in the southwest region, with records of vulnerable species according to the IUCN such as Puma concolor, Tapirus terrestris and Myrmecophaga tridactyla.
