Abstract

Lowland savannas in northern South America (llanos) occupy a region with a pronounced rainfall seasonality with four to six months dry season and 600 to 1,500 mm rainfall. This seasonality is considered to be determinant in savanna phenology, although species with divergent rhythms have been reported (Monasterio, 1968) due to water availability during the dry season (Vareschi, 1960).
