![عکس صفحه اول مقاله: Underlying thermodynamic relations of a species diversity index: Freshwater crabs from Colombia Underlying thermodynamic relations of a species diversity index: Freshwater crabs from Colombia](/preview/png/4373930.png)
The goal of this paper is to apply the theoretical method described in Campos (2011) to the characterization of an ecological system represented by data corresponding to a collection of freshwater crabs consisting of 100 species and 6397 specimens recorded in Colombia between 1910 and 2010.The registers in the collection are translated into a set of probabilities (relative abundances) P={P1,P2,…,PN}P={P1,P2,…,PN}, where NN is the species richness. The index for species diversity is calculated as the product of a function of the species richness times a function of the Helmholtz free energy F(P,q)F(P,q), where the entropic parameter q allows the system to be considered under various hypothetical environmental conditions.
► An ecological system represented by a collection of freshwater crabs is considered.
► Hypothetical environmental conditions are described by an entropic parameter q.
► A geometrical species diversity index allows the characterization of the system.
► Geometrical index has some advantages over Shannon measure of ecological diversity.
