Dear list members: We would like to draw your attention to the following session at the 2006 American Geophysical Union (AGU) Fall Meeting in San Francisco (December 11-15, 2006) and invite you to submit an abstract before September 7, 2006.
B27. Savanna ecosystems: Field observations and manipulation experiments. Sponsor: Biogeosciences CoSponsor: Hydrology Global Environmental Change Session Description: Savanna ecosystems, covering about 20% of the Earths land surface, are transitional zones between forested environments and grasslands, and represent areas sensitive to climate change. Influential factors for the changing productivity of savannas include for example, local hydrology, atmospheric circulation, and nutrients. An example of a savanna that could be reported on in this session is the Kalahari. This savanna, situated in central southern Africa, represents an ancient biome, which has evolved to its present state over millions of years. The Kalahari sand sheet occupies 2.5 million ha in southern Africa, probably represents the largest continuous surface of sand in the world. The Kalahari transect is an IGBP Mega transect dominated by different types of savanna vegetation. It is an area with relatively similar deep aeolian soils, and a strong south to north gradient in rainfall, from 200 mm in the south to more than 1000 mm mean annual precipitation (MAP) in the north. These factors provide an excellent basis for gradient studies at the subcontinental scale and a testing bed for global carbon and vegetation models without confounding soil effects. In this session, we seek contributions describing results from field observation, field manipulations, modeling studies, and remote sensing studies that address water, carbon and nutrient dynamics and their interactions in Kalahari region as well as other savanna ecosystems.
