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).
