In order to acquire a practical methodology of great use for the B_NN computation and its involved dynamics, that contains a large potentiality in the use of decisions for the continuity and optimization of natural resources as well as for the acquisition of the maximum sustained yield (MSY), we use the B_NN annual empirical models for the different ecosystems from climatic parameters like: temperature, rainfall, evapotranspiration and aridity indexes. The stability of the annual B_NN for different ecological environments by comparing the eigenvalues of the communitary matrix resultant from biological interaction with the variance of the climatic environmental randomness (precipitation) is also computed. The sensibility response of ecosystems is derived by a theoretical Hamiltonian model transformed to a statistical problem.
