The degradation of pequi (Caryocar brasiliense Camb.) from the Brazilian cerrado biome (a savanna type) is calculated, with an emphasis on the valuation of social costs imposed on society by the reduction and loss of forest cover from 1990 to 2008. To measure the social costs, the Marshall economic surplus concept was used, which measures the level of consumers', farmers' and forest communities' welfare. From 1990 to 2008, the estimated average social costs were of Rs 922 thousand. Of this loss, 44% affected consumers and 56% affected producers. Therefore both supply and demand loose with damages to the cerrado biome. Source

This study evaluated the wood samples of root, stem at three heights, and the branches of three young trees of Eriotheca gracilipes (K. Schum.) A. Robyns-Malvaceae. The trees were collected in the Assis State Forest in a region of the cerrado strictu sensu. The anatomical analysis followed the usual techniques for wood anatomy. The results revealed that the changes found in the axial direction may reflect different stages of development of the vascular cambium, but also indicate an adaptation of plants to environmental conditions, such as the presence of a dry period between April and September and the characteristics of the vegetation with sparsely distributed trees and, therefore, subject to windstorms and/or rain.
