Spatial distribution of the genetic variation in Araucaria angustifolia

Araucaria angustifolia is the only species belonging to the family Araucariaceae which is naturally growing in Brazil and is located mainly in the southern part of Brazil. Reduced to about 3% of the original area, this species is nowadays listed as vulnerable in the IUCN Red List of Threatened Species. The aim of the project is to characterize the spatial distribution of the genetic diversity within and among remnant populations of A. angustifolia by means of nuclear and cpDNA molecular markers. It is expected that the results will be useful for programs of conservation and breeding of this species.
