In consideration of the environmental dynamics, it is often found that it is strongly controlled by climatic factors such as atmospheric temperature, rainfall, sunshine, etc.. Similarly, the evolutionof ecosystems and biomes is ruled by climate change incidents in regional, continental and global.
The Cerrado biome, which includes the most significant part of the Ecological Corridor ProjectJalapao Region, Central Brazil is installed for at least 40,000 years and its evolution is occurringin dynamic equilibrium with climate change (Labouriau-SALGADO, 2005).
At the end of the last glaciation, between 36,000 and 28,000 years before present (BP), in forcein the region humid and relatively cool (Labouriau-SALGADO, 2005; Suguio, 2010). These conditions lasted until 20,000 years BP, as indicated by the absence of pollen of the palmMauritia sp. (buriti). The deglaciation in the Holocene (12,000 years BP) was followed by a longdry spell and hot. These drier conditions than the current ones were until about 7,000 years BP.After 5,000 years BP prevailed a semi-humid climate with a well defined dry season, similar to the current climate. The advent of wetter conditions is evidenced by the development of alluvialand colluvial deposits. Thus, features of lakes, wetlands and trails have become so common in Central Brazil.
