  Climate change is expected to lead to more frequent, intense and longer droughts in the future, with major implications for ecosystem processes and human livelihoods. The impacts of such droughts are already evident, with vegetation dieback reported from a range of ecosystems, including savannas, in recent by: Gary S. Hartshorn, in Encyclopedia of Biodiversity (Second Edition), Savannas. Savannas are defined as having a continuous cover of grass, but trees may be conspicuous components of savanna landscapes. Though vast areas in the major tropical regions meet the criteria for savannas, it is much more difficult to ascertain if it is natural or derived through human activities (e.g., burning). The future for savanna and tropical grasslands: A Latin American perspective Article (PDF Available) January with Reads How we measure 'reads'. The savanna is an open landscape of grasslands found in tropical Africa. It is home to an amazing variety of wildlife. For half of the year, savannas are hot and dry, and swept by wildfires. They also have a season of heavy rains. Tall grasses grow during the rainy season, providing food for herds of grazing animals such as zebras and wildebeest.

The Savanna Biome is a thriving semi-grassland located in Africa. Spanning almost 5 million square miles the Savanna Biome takes up almost 50% of the continent. The future for this biome is very bright thanks to the animals that work in perfect harmony to maintain biodiversity throughout the biome. Search all new, secondhand, antiquarian books and artwork.

Tropical savannas occur in the seasonal tropics of Africa, South America, Asia and Australia. A dense grass layer is a defining feature, but vegetation structure varies from essentially grasslands with sparse trees, especially on cracking-clay soils, to open forests with a mixed understorey of shrubs and grasses, typically on deep sandy loams with high annual rainfall.

Savanna - Savanna - Environment: In general, savannas grow in tropical regions 8° to 20° from the Equator. Conditions are warm to hot in all seasons, but significant rainfall occurs for only a few months each year—about October to March in the Southern Hemisphere and April to September in the Northern Hemisphere. Mean annual precipitation is generally 80 to cm (31 to 59 inches. AbstractGlobal change may induce changes in savanna and forest distributions, but the dynamics of these changes remain unclear. Classical biome theory suggests that climate is predictive of biome distributions, such that shifts will be continuous and reversible. This view, however, cannot explain the overlap in the climatic ranges of tropical biomes, which some argue may result from fire.   General Overviews. The savanna biome has been the subject of a number of broad overviews. In the landmark Ecosystems of the World series Bourliére provides a comprehensive overview, Tothill and Mott provides global treatment of savannas, and the ecology of tropical savannas is covered in Huntley and Walker , but none of these books are currently in print. Synthesizing theoretical and empirical analyses of the processes that help shape these unique ecosystems, Tropical Rainforests looks at the effects of evolutionary histories, past climate change, and ecological dynamics on the origin and maintenance of tropical rainforest communities.
