Comparative fire ecology of tropical savanna and forest trees

摘要: Summary 1Fire is important in the dynamics of savanna–forest boundaries, often maintaining a balance between forest advance and retreat. 2We performed comparative ecological study to understand how savanna species differ traits related fire tolerance. We compared bark thickness, root stem carbohydrates, height reproductive individuals within 10 congeneric pairs, each containing one species. 3Bark thickness averaged nearly three times that species, thereby reducing risk death during fire. The allometric relationship diameter differed these two tree types, with tending have larger coefficient. 4The twice species. This should increase time necessary for reach size, their capacity maturity consecutive fires. 5There was no difference total non-structural carbohydrate content stems or roots though greater allocation biomass by probably confers resprout following fire. 6These differences fire-related may largely explain persist environment.
