“…Nearly 300 muriquis, representing approximately one third of all living individuals, are distributed in seven known social groups in the Caparaó National Park (Kaizer et al, 2016(Kaizer et al, , 2017, a federal conservation unit of 31,853-ha located on the border of the states of Minas Gerais and Espírito Santo. On the 3rd of May, 2018, a solitary adult female northern muriqui was encountered during a routine survey conducted by the park managers in a small and isolated forest fragment surrounding the Caparaó National Park (W.P.…”

Conservation translocation may play an important and necessary role in primate conservation as several species are facing an impending extinction risk and population decline. However, translocations are a high-cost endeavor. Therefore, pre-capturing monitoring can be an essential component in the success of primate translocation. In this study, we report the first confirmed sighting of a female Northern Muriqui (Brachyteles hypoxanthus) stranded alone in a small fragment of Brazilian Atlantic Forest, and her pre-capture monitoring for a future planned translocation. Monitoring was realized from June 2018 to July 2019, and included data collection through direct observational and arboreal camera trap methods, and non-invasive collection of faecal samples for additional genetic studies. Our results showed that the female used the total area of the 1-ha forest fragment with an average daily displacement of 59.6 m ± 76.2. The female spent most of the time ‘Resting’, followed by ‘Travelling’ and ‘Feeding’, which did not vary significantly between seasons. Intraspecific activity pattern variations may be related to the amount and quality of the feeding resources available in the forest fragments. No stereotyped behavior or advertising signals were reported during the monitoring. Our study provides insights on solitary primates living in marginal habitats and highlight the importance of pre-capture monitoring to provide important information on the general behavior of the target individuals, on the regular movements and overall home ranges, and to help to guide future translocations.

The Atlantic Forest of South America supports a rich terrestrial biodiversity but has been reduced to only a small extent of its original forest cover. It hosts a large number of endemic mammalian species but our knowledge of arboreal mammal ecology and conservation has been limited because of the challenges of observing arboreal species from ground level. Camera trapping has proven to be an effective tool in terrestrial mammal monitoring but the technique has rarely been used for arboreal species. For the first time in the Atlantic Forest, we obtained data on the arboreal mammal community using arboreal camera trapping, focusing on Caparaó National Park, Brazil. We placed 24 infrared camera traps in the forest canopy in seven areas within the Park, operating them continuously during January 2017–June 2019. During this period the camera traps accumulated 4,736 camera-days of footage and generated a total of 2,256 photographs and 30-s videos of vertebrates. The arboreal camera traps were able to detect arboreal mammals of a range of body sizes. The mammal assemblage comprised 15 identifiable species, including the Critically Endangered northern muriqui Brachyteles hypoxanthus and buffy-headed marmoset Callithrix flaviceps as well as other rare, nocturnal and inconspicuous species. We confirmed for the first time the occurrence of the thin-spined porcupine Chaetomys subspinosus in the Park. Species richness varied across survey areas and forest types. Our findings demonstrate the potential of arboreal camera trapping to inform conservation strategies.

The Atlantic Forest of South America supports some of the greatest terrestrial biodiversity on our planet but is now reduced to only a small extent of its original forest cover. It hosts a large number of endemic mammalian species but our knowledge on arboreal mammal ecology and conservation has been hindered by the challenges of observing arboreal species from ground level. Camera trapping has proven to be an effective tool in terrestrial mammal monitoring, but the technique has rarely been used for arboreal species. Here we generated data on the arboreal mammal community based on canopy camera trapping for the first time in the Atlantic Forest, focusing on Caparaó National Park, Brazil. We placed 24 infrared camera traps in the forest canopy distributed in seven areas within the Park, operating continuously from January 2017 to June 2019. In this time, they accumulated 4,736 camera-days and generated 2,256 sets of pictures and 30 second videos of vertebrates. Canopy camera traps were able to detect arboreal mammals spanning a wide variety of body sizes. The local mammal assemblage comprised of 15 identifiable species, including the critically endangered northern muriqui (Brachyteles hypoxanthus) and the buffy-headed marmoset (Callithrix flaviceps), and other rare, nocturnal and inconspicuous species. For the first time, we confirmed the occurrence of the thin-spined porcupine (Chaetomys subspinosus) in the Park. Species richness varied across sampling areas and forest types. Our findings demonstrate the potential of canopy camera trapping for future surveying efforts to better inform conservation strategies for mammals.
