Post-fire resprouting strategies of woody vegetation in the Brazilian savanna Acta Botanica
Souchie,Fabiane Furlaneto; Pinto,Jose Roberto Rodrigues; Lenza,Eddie; Gomes,Letícia; Maracahipes-Santos,Leonardo; Silvério,Divino Vicente.
ABSTRACT Post-fire response by vegetation may reflect the severity of the damage suffered, but we still know little about the species-specific nature of responses to fire or their predictors. Here, we evaluated 26 woody species before and after a fire event in an Cerrado sensu stricto area (typical Brazilian savanna-type) in order to evaluate mortality rates and the type of resprouting (epigeal, hypogeal or epigeal + hypogeal). We evaluated the relative importance of stem diameter, height, and bark thickness as predictors of the type of post-fire resprouting, using a sequential logistic regression model (SLRM). Mortality was 4 %, while epigeal resprouting was recorded in 57 % of the individuals, hypogeal resprouting was recorded in 24 %, and epigeal +...
