Water availability was limiting to trees because, at the spatial grain of our. They have been shown to have high levels of vitamin C, calcium, iron, and magnesium. This feature, in combination with the surface fire regimes that are typical in savannas, results in very low fire-related mortality in adult savanna trees. Savannas are home to a wide diversity of animals. Using a well-sampled, time-calibrated phylogenetic tree of the woody flora, we examine the timing of 139 evolutionary splits between savanna trees in Africa as a marker for the age of the savanna biome. While also flat and lacking many large trees, this biome differs from its tropical counterpart in that it experiences generally cooler, and more varied, temperatures year-round. The original list was rainforest, seasonal forest, forest, shrubland, taiga, tundra, plains, swampland, desert, frozen desert, and savanna. Another adaptation that enables the baobab tree to survive the long months of drought is its ability to store water in its large trunk. -permafrost. , scattered trees) above a continuous tall grass understory (the vegetation layer between the forest canopy and the ground).

Thus, when fires are absent and water supply is suffi-cient, forest trees outcompete. Vegetation on the African savannas, for example, feeds animals including zebras, wildebeest, gazelles, and giraffes. A great amount of sunlight reaches the upper canopies, but very little sunlight filters down to the understory and forest floor. Grasses and trees that grow in the savanna have adapted to life with little water and hot temperatures. The modeled savannas occupy the hot and arid envelopes of the climate space (Fig. ecotone.
