SPECIES DIVERSITY PATTERNS DERIVED FROM SPECIES–AREA MODELS

Ecology, 2002
Although area, species abundances, spatial distribution, and species richness have been central components of community ecology, their interrelationships are not completely understood. To describe these interrelationships, we study and test three patterns regarding species richness using species-area models.

Species Diversity and Biomass Stability

The American Naturalist, 2000
With the current accelerating rate of biodiversity extinction, there is great interest in how species diversity influences ecosystem properties. In this article, we investigate the relationship between species diversity and the stability of community biomass in the face of stochastic perturbations of species' abundances.

Tryptophanase in Diverse Bacterial Species

Journal of Bacteriology, 1969
The distribution of tryptophanase was studied. The highest observed specific activity, μmoles per minute per milligram (dry weight) cells, is given in parentheses after each species. Tryptophanase was inducible and repressible in Escherichia coli (.914), Paracolobactrum coliforme (.210),

Species diversity can drive speciation

Nature, 2005
A fundamental question in evolutionary ecology and conservation biology is: why do some areas contain greater species diversity than others? Island biogeographic theory has identified the roles of immigration and extinction in relation to area size and proximity to source areas, and the role of speciation is also recognized as an important factor ...

Linking Species Diversity and Landscape Diversity

2005
Ecologists generally agree that species diversity is linked to landscape features (Pickett and White 1985, Glenn et al. 1992, Wiens et al. 1993, Rosenzweig 1995, Hoagland and Collins 1997, Ritchie and Olff 1999). We present a conceptual framework for connecting species diversity and landscapes by showing how changes in species assemblages and changes ...

Trophic structure and species diversity

Journal of Theoretical Biology, 1977
Abstract This paper considers a model of an ecosystem in which interactions between species are described by pathways for energy flow. We introduce a new measure of diversity which incorporates the complexity of interaction between the various populations in the trophic web.
