We started in 2010 as a small group having meetings every month or so to discuss some environmental issues occurring in the Central Brazilian Savannas and how we could use the isotope methodology combined with geospatial analysis to help to give a more precise picture about those environmental problems. Some undergraduate students started to join the meetings and it evolved to a more strengthened group in the following years. Most of them are currently graduate students (master and doctoral) but some professionals also integrated the group bringing the discussion to another level of commitment. After a decade of using and applying the stable isotope methodology in different but correlated areas, we are now a consolidated group in stable isotope data interpretation for the Neotropics.
