Effect of dyke construction on water dynamics in the flooding savannahs of Venezuela
(2006)
In the flooded savannahs water is the main factor determining the ecosystem and its change.
During flooding, the level of water and the duration of flooding are highly dependent on
the relative height position of the ecosystem ...
O caso das savanas tropicais da América do Sul: quando a sustentabilidade econômica e ecológica não é suficiente
