- Abstract
The Atlantic Forest can be divided into vegetation types in the state of Paraná. The main types are: Araucaria Forest (FOM), Rain Forest (FOD) and Forest Semideciduous (FES). Due to global climate changes, some forest formations will suffer displacement and the physical space they currently occupy will be changed. The more sensitive vegetations will suffer decline, giving way to others, with more adapted species the new conditions. The objective of this study was to evaluate and calculate the reduction and expansion of the areas of vegetation types in Paraná caused by climate change, through the modeling of ecological niche. For this, we calculated the averages of minimum, medium and maximum sazonal air temperature and the total annual cumulative rainfall for both: base period and the future climate scenarios. Climatic data were organized into information layers, using GIS, and analyzed according to the climate change scenarios defined by the 4th Intergovernmental Panel on Climate Change report (AR4 / IPCC). The location of occurrence of various vegetation types were obtained by the generation of equidistant points within the polygons defined by ITCG/SEMA (State Department of Environment). We observed that there will, by the year 2090, a FOM decrease of 96% and a FES increase of 72% and no significant changes will occur in the FOD. With these results, this work contributes to the formulation of public policies, providing information on the areas most suitable for preservation of vegetation types and where there should be priority in the rescue of genetic material for the preservation of genetic variability.
