The main determinants of tropical savannas are plant available moisture (PAM) and plant available nutrients (PAN). Fire (F) and herbivory (H) are secondary determinants in a hierarchy of factors which produce the characteristics of any particular savanna (Solbrig 1991). While the biodiversity of a savanna are will be influenced by the biogeographic pool of species available to the region at any given time, the structure and productivity of the savanna are controlled by PAM an PAN, which in turn also influence biodiversity. Fire and herbivory then modify biodiversity directly through the mortality of individuals and directly through effects on the resources by individuals using different fuel types. Also biodiversity, through the range of food resource qualities, helps to determine the impact level of herbiroy on the ecosystem. |
