Savannas are a major terrestrial biome, comprising of grasses with the C4 photosynthetic pathway and trees with the C3 type. This mixed grass-tree biome rapidly appeared on the ecological stage 8 million years ago with the near-synchronous expansion of C4 grasses around the…

Fire has been shown to stimulate seed germination in a number of fire-prone ecosystems, mainly in Mediterranean type shrublands and, though not exclusively, in hardseeded species. Stimulation by heat, or by chemical constituents of charred wood and smoke, have been identified as…

Soil seed banks that persist after a fire are important in fire-prone habitats as they minimise the risk of decline or local extinction in plants, should the fire-free interval be less than the primary juvenile periods of the species. In two common woody plant genera (Acacia and…
