Species richness (SR) per lake ranged from seven to 26 (mean = 13.22, SD = 4.48) and functional dispersion (FDis) ranged from 0.09 to 0.23 (mean = 0.16, SD = 0.04). We try to gain insight to this paradox, by analyzing a simple model of a diverse community where each competing species inflicts a small mortality pressure on an introduced predator. Genetic diversity. The diversity of our biosphere ranges from macromolecules of a cell to different biomes.Genetic diversity, species diversity, and ecological diversity are three types of biodiversity. - Biodiversity of Fishes Diversity of the Oceans Rainer Froese 29.01.09 Fish Diversity of the Oceans Diversity in Large Marine Ecosystems Environment by Half-degree ...
