Research Objectives: This is a long term field project on primate ecological research, which has been investigating the natural factors affecting natural food choice of Brachyteles arachnoides and Alouatta fusca. A main field site and main study groups are located at the North Sector of Carlos Botelho State Park. In addition, the field team works on four additional field sites on three different physiography of Brazilian Atlantic Forest within São Paulo State: Serra do Mar, Serra da Mantiqueira and Serra de Paranapiacaba. For these additional field sites, the main focus is currently on monitoring wild populations of southern muriquis. Master and Ph.D research positions are open for discussion after a successful volunteering experience of minimum six months

Field Positions and Volunteers: Two long term positions for field assistants are available at a continuous basis. Background experience desired but not essential. A certificate from both University and NGO will be available for the volunteers selected and we are open for proposals on undergraduate conclusion work from both Brazilian and International Universities.

After arrival in GRU airport, transport from Airport at arrival and accommodation during the period of your commitment are provided.

The activities can be resumed as locating and following the subgroups of woolly spider monkeys in the forest, marking food trees, collecting botanical material (for later same day processing for taxonomy identification), measuring trails, GPS plotting and plus general field work activities. After returning to the camp, evening activities includes cooking, processing botanical material, phyto-chemical computer processing techniques and transcriptions of data for paper sheets as well computer sheets. It is expected that around 08:30 Pm all activities have been done, with 10:00 PM silent starting for rest, with a new day starting next morning 5:30 AM. It is offered the chance of learning and experiencing field biology and related field primatology activities and techniques that are used at the present study of this long term project. Driving experience desirable. A small and simple camp house at a lovely farm surroundings is offered. One day off a week. Internet is provided at no cost and shut at 10 pm (GMT-3:00). Fit people (or desiring to get fit in two months) required for activities that depending on your physical development can gradually reach some days or week of extreme level of difficulty

Species Studied: Alouatta clamitans (howler monkey), Brachyteles arachnoides (southern muriqui)

Comments: This study is the only systematic study existing for Brachyteles on continuous Atlantic Forest. It is the longest for the species (20+ years) and we open for discussing any kind of volunteering position or potential academic collaborations. Our interests are broad and all aspects of Life Sciences relating to Atlantic Forest, Primates, Ecology, Behavior, Bio-geography, Genetics and Ecosystem Health just to mention some of the areas amongst many that are feasible to design professional academic or under/graduate ou volunteering studies.
