Abstract

Originally, 20% of the Earth crust was occupied by savannas. The savanna's biome flora basically comprises three physiognomies: "campos rupestres", savannas and forests. In relation to shrubs/trees, it is possible to group them in three functional groups according to their deciduousness: evergreen, semi-deciduous and deciduous species. In order to realize this classification, an ecophysiological study will be conducted among the deciduousness functional groups between Australian and Brazilian savannas. In Brazil, we will study the savanna communities close to Brasília - DF and Itirapina - SP municipality, and in Australia the communities close to Darwin and Alice springs municipalities (North State). The aims of this study are: 1- evaluate the macronutrients and aluminum contents on leaves, specific leaf area (SLA) and phylogenetic relationships between Australian and Brazilian savanna biomes; 2 - establish a scientific agreement between Instituto de Biociências- UNESP campus from Rio Claro and The University of Queensland; 3 - exchange scientific experiences about the Brazilian and Australian savanna's research. We intend to answer the following questions: How much is variable the nutritional pattern (macronutrients and Al3+) and SLA among the functional groups from Australian and Brazilian savanna, considering the soils differences (they will be characterized too)? Is there any phylogenetic relationships between the Al3+ accumulation and the functional groups and biomes? (AU)
