Book excerpt: Fire is an important factor affecting plant diversity and vegetation dynamics in subtropical grasslands in southern Brazil. Although fire is a useful management tool in many ecosystems, in Brazil its use is forbidden and very polemic. Therefore, the aim of this thesis is to evaluate the effects of fire on plant strategies and vegetation dynamics. The study was carried out in southern Brazil (Rio Grande do Sul State). Experimental fires and mowing were performed and vegetation regeneration was analyzed according to different functional groups and plant strategies. In addition, population biology of chosen species was studied in order to investigate effects of fire on plant populations. Finally, studies about the bud bank were conducted to evaluate vegetation potential to regenerate after fire events. The results of this thesis are of crucial importance for the conservation of subtropical grasslands in southern Brazil.
