Predation and species diversity

Journal of Theoretical Biology, 1974
Except for doubtful interactions with interference competition and density-dependent extinction, equivalent predation cannot increase the number of species of prey.

Relationship between species diversity and ecotope diversity

Annals of the New York Academy of Sciences, 2010
The relationship between species diversity and ecotope diversity has long been debated. But these debates seem meaningless because most of them were based on different definitions. In this paper, diversity has two components: richness based on the total number and evenness based on the relative abundance.

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 in Local Neutral Communities

The American Naturalist, 2007
We extend the neutral theory of macroecology by deriving biodiversity models (relative species abundance and species-area relationships) in a local community-metacommunity system in which the local community is embedded within the metacommunity. We first demonstrate that the local species diversity patterns converge to that of the metacommunity as the ...
