influence on the annual growth rings, but the occurrence of precipitation coupled with low
temperatures reduces the growth of them. With the simulated climate scenarios, presented in
this research, for the four cities of Campos Gerais, Parana State, one can deduce that at best,
which projected an average increase of 1.4°C in the average temperature and 14% increase in
precipitation, future changes will be possibly positive as regards the development of Araucaria
Forest. However, for a scenario with an increase of 5.8°C in the average temperature and 58%
increase in the amount of precipitation, extreme events may occur daily for these climatic
elements which, according to Kramer and Kozlowski 1960, influence negatively the hydration
and dehydration of the trees, which may result in variations in the diameter growth during the
twenty-four hours a day.
