The Cerrado is a patchwork of phytophysiognomies with dominance of savannah, placed in the Dry Diagonal, wide corridor in the center of the Neotropical region. Relate with one of the major world's hotspots to preservation and conservasion, with the minor percentage of protected areas in Brazil. It has 2,000,000 Km2 of size (24% of the brazilian territory), and high since sea level until 1800m. This great size and high's variation provides to Cerrado different condicions of temperature, moisture, rainfall, water availability, soil traits, richness, among others, interfering in the species adaptation and consequently, in its diversity and distribution. In order to study the influence of climatics and environmentals factors over the species distribution, become needed initially research which elements are shaping this distribution. Meta-analysis facilities as the Principal Component Analysis (PCA) alow check the factors that more responds the noticeable phenomenons (in this case, the species distribution), and provides exploratory outcomes to look into the adaptation of species in environments as distincts as the attending in Cerrado. The current survey aim investigate which climatics and environmentals factors more impact on species distribution in Cerrado, using as study's organism species of the genus Acanthoscurria Ausser 1871 (Araneae, Mygalomorphae: Theraphosidae).
