ABSTRACTThe frequency of genes in interconnected populations and of species in interconnected communities are affected by similar processes, such as birth, death and immigration. The equilibrium distribution of gene frequencies in structured populations is known since the 1930s, under Wright’s metapopulation model known as the island model. The equivalent distribution for the species frequency (i.e. the species proportional abundance distribution (SPAD), at the metacommunity level, however, is unknown. In this contribution, we develop a stochastic model to analytically account for this distribution (SPAD). We show that the same as for genes SPAD follows a beta distribution, which provides a good description of empirical data and applies across a continuum of scales. This stochastic model, based upon a diffusion approximation, provides an alternative to neutral models for the species abundance distribution (SAD), which focus on number of individuals instead of proportions, and demonstrate that the relative frequency of genes in local populations and of species within communities follow the same probability law. We hope our contribution will help stimulate the mathematical and conceptual integration of theories in genetics and ecology.

In the reviewed literature, dispersion was identified in the concepts used in the definition of dynamic capacities (CD), incomplete theories were also observed on which the proposed concepts were based, which has hindered the development of theoretical knowledge and the conduct of research empirical. The effort of the authors to solve this problem has been partial since it was analyzed from the perspective of strategy theory, the theory of organizations and administration (TOA) was not considered, this situation affected the clarity and precision of the CD. The objective was raised, to build the concept of dynamic strategic and organizational capacities (CDEO) based on the theories of strategy (TE), organizations (TO) and administration (TA), in order to modernize the traditional concept dynamic capabilities (CD) and provide a solution to the concept dispersion problem. Originality. Integration of theories around the CDEO construct, which will allow the theoretical and empirical development.
