Dinâmica temporal do estrato Herbáceo-arbustivo (abril – 2000 e maio – 2007) de uma área de campo limpo úmido em Alto Paraíso de Goiás, Brasil

Abstract

(Long-term dynamic of the herbaceous-subshrub layer (April – 2000 and May 2007) in a campo limpo úmido (moist grassland) in Alto Paraíso de Goiás, Brazil). Long term studies are needed to understand the dynamics and key environmental factors that determine the structure of the community in order to develop strategies for conservation and sustainable use of the biodiversity. The objective of this study was to evaluate the dynamics structural and community and flora species of the herbsubshrub layer in an campo limpo úmido in Alto Paraíso de Goiás, through inventories that were made in the last half of April 2000 and in the first half of May 2007, on 15 lines of 10 m, permanently installed in the first inventory, and the composition and coverage across-the-board species determined by the intersection method on the line. There was high similarity between periods and significant difference in diversity (t = 45, 611 p < 0,01), after a period of seven years of the first inventory. There was high similarity between periods and diversity (t = 45,611 p < 0,01) of species between inventories which suggest that the community area grassland place, variations in structure than in its composition florística, over time.
