Selecting ecotonal landscape units on Meridional Plateau, Southern Brazil

The Escarpa Devoniana environmental protection area, located in the Meridional Plateau of South Brazil, supports a high diversity mosaic of native araucaria (Araucaria angustifolia) forests and grasslands patches. In order to conduct studies of its dynamics, the biodiversity of grassland-forest ecot...
