Abstract
Araucaria angustifolia is an endangered tree of high economic value, which belongs to the Brazilian subtropical forest of high altitude. This species is considered under risk of extinction due to its previous exploration and dizimation, mainly for its valuable wood. Although A. angustifolia nowadays occupies only a very restricted area of the state of São Paulo, this ecosystem presents a high biodiversity of plants, animals and microorganisms. The loss of this biodiversity could imply the loss of sustainability of the forests. The main objectives of this research project are to survey the plant and microbial biodiversity of the ecosystem and their interactions. The specific objectives are: a) to characterize the floristic biodiversity; b) to identify the structure of the associated soil-borne microbial community, using molecular (DGGE) and biochemical (Biolog) techniques; c) to isolated and identify, through morphologic and molecular methods, the arbuscular mycorrhizal fungi associated to Araucaria; d) to isolated and identify the associated diazotrophic, rhizospheric or endophytic bacteria; e) to evaluate the soil biochemical processes, as C or N microbial biomass, CO2 evolution, the metabolic coefficient and enzymatic soil activity; f) to study the genetic variability between individuals of the Araucaria forest employing molecular markers - RAPD and ADLP or DNA sequences of organelles; g) to survey the diversity of the macrofauna and to estimate the importance of certain functional groups; h) to obtain this information with regard to the two contrasting seasons (summer and winter), in two regions of the state of São Paulo (Campos do Jordão and Apiaí), in native and disturbed ecosystems.
