2 METHODS
The geographic area investigated belongs to the central-north region of Brazil, focusing on marginal and disjunct savannas in relation to the continuous block of the Cerrado biome. The aim was to investigate the effects of climate change on different savannas showing the influence of adjacent phytogeographic domains. Projections and analyses are mainly concentrated in the North and Northeast regions (approximate limits 6°N, 19°S, 74°O and 34°O), covering the Amazon, Cerrado, Caatinga and their ecotonal areas, involving natural climatic boundaries between rainforests, savannas and semi-arid steppes (IBGE, 2012). The studied area is one of the Cerrado’s biodiversity and endemism supercenters, but lacks information on primary biological data, and therefore represents a preferred target for collections (Vieira, Costa-Coutinho, Castro, & Martins, 2019). Furthermore, research indicates that this area is more sensitive to global climate change due to the current high rates of deforestation and landscape transformation (Salazar et al., 2007; IPCC, 2014).
