Entropy and diversity
Article Abstract:
The significance of transformation of alpha, beta and gamma entropies by applying it to a popular community similarity measure based on raw diversity indices or entropies is shown .The transformation of entropies to effective numbers of species yields a stable, interpretable, sensitive general similarity measure and Jaccard Index, Sorensen Index, Horn index of overlap and the Morisita-Horn index are general overlap measures derived from transformed similarity measure yield.

A stochastic model for integrating changes in species richness and community similarity across spatial scales
Article Abstract:
The influence of differing patterns of extinction and invasion on the similarity and richness of a meta-community is investigated. The results have shown that in real systems, the influence of human-induced invasions and extinctions on diversity will depend on both the precise mode of these processes and how species populations are distributed across space.

Do generalized scaling law exist for species abundance distribution in mountains?
Article Abstract:
An elevational gradient in a warm temperature zone of the Donglingshan mountains (China) is used to test the scaling laws of spices abundance distribution using multifractional analysis. The fact that power-laws exist across a heterogeneous landscape representing a strong bioclimatic gradient has indicated that biodiversity scaling laws is more robust.
