The cave environments constitute one of the ecosystems of fundamental importance in nature, due to the great biodiversity of species found in these environments, the geological characteristics, the drainage patterns, the speleothems and the patrimonial, social and economic representativeness for the populations that live close to these areas (BUECHER, 1999; LINO, 2001). The understanding of the climatic aspects of caves is necessary for the generation of data that allow the atmospheric modeling of these environments, and the observation of the variables or characteristics found in the microclimate of caves. This is of great importance in the planning and management of natural resources, assisting in the management, planning and conservation of these environments (FREITAS, 2010). Resulting in an important tool to support research on cave environments. In most studies on cave environments, there is a strong presence of works related only to the geology of caves, denoting a lack of studies on the internal microclimatic processes of caves throughout Brazil (LOBO, 2010). The microclimatic scale comprises the atmospheric variations over the surface varying in height according to the aspects found in the landscape (MONTEIRO, 1990; MENDONÇA; DANNI-SILVA, 2007). Becoming the best scale for evaluating the cave atmosphere. Monitoring by means of thermohygrometers that store daily data, statistical analysis and comparison between graphs, allowed us to evaluate the microclimate in the cave Lapa do Boqueirão, located in the municipality of Vila Propício. State of Goiás. The acquired information revealed significant differences of the thermal variability of the cavity in relation to the external environment. Presenting circulation patterns and internal regulation mechanisms of thermal variability between environments that corroborate the characteristic specificities of a microclimate (LUETSCHER; LISMONDE; JEANNIN, 2008; LOBO, 2012). The results obtained in this research serve as support and contribution to studies conducted on the speleological landscape, especially those that consider the microclimatic parameters, and can assist in scientific analysis and decision-making of priority caves for conservation and preservation.
