2.1.1 Pantanal
The Pantanal has a high biodiversity and is one of the largest continuous freshwater wetlands on earth (160,000 km2) (Franco et al., 2013). In this pristine region, the study area was located at a private ranch (Baía das Pedras) in the Nhecolândia sub region of the Pantanal (19°20’ S, 55°43’ W). (Fig. 1)
