Biodiversity and Nutrient Relations in Savanna Ecosystems: Interactions Between Primary Producers, S1988; McNaughton 1990). This production of biomass can be brought about by assemblages of primary producers composed of widely different species. Similar environments on different continents attain the same level of organic matter production, and are occupied by more or less equivalent ecosystems in

Biodiversity and Water Relations in Tropical Savannasing several components of the biota such as microorganisms, non vascular plants, invertebrates, and even vertebrate animals. Fortunately, enough is known of the vascular flora of several savanna communities to allow some comparisons. Unfortunately, the information on the functional groups within the

Ecophysiological Aspects of the Invasion by African Grasses and Their Impact on Biodiversity and Funy ability, and biogeographical barriers. During Earth’s history, these natural processes have been responsible for the assembly of communities through coadaptation and coexistence of species of distinct origin in a common environment. With human mediation, biological invasions have been gradually ac

Relationships Between Biotic Diversity and Primary Productivity in Savanna Grasslandss no compelling evidence indicating that higher plant biodiversity should result in higher primary production, it has been frequently assumed that the cooccurrence of different biological forms may increase the efficiency of interception of incident radiation. As a consequence, a number of “humped”

Biodiversity and Fire in the Savanna Landscapepopulations, certain kinds of tissues are resources, but not their diversity as such. Diversity is a defining characteristic of life. In order to deal with it scientifically, we need standard ways of measuring it. Biodiversity has been operationally defined as a hierarchical product of genetic, spec

Diversity of Herbivorous Insects and Ecosystem Processesnto 1984). The major exception, of course, are African ungulate herbivores, whose impact on savanna and grassland ecosystems has received some attention (McNaughton 1976; Sinclair 1983). Plant-eating insects, on the other hand, are hardly mentioned except as pollinators (Cole 1986).

Biodiversity and Stability in Tropical Savannasature of perturbations taking place in savanna communities, and will put forward the hypothesis that the relative stability of a community on the face of a perturbation depends on its floristic structure. The structure of a plant community, or floristic structure, is used here in a phytosociological

Savanna Biodiversity and Ecosystem Propertiested in two different ways. It can refer to the flow of energy and nutrients through an ecosystem or to the flow of species populations through time, i.e., the persistence of species populations and their properties, which we call the structure of the system. Here we discuss the effect of biodiversit
