Ítem Embargo Enlarging simple ecological models:subspecies, hidden symmetries and thei implications(Springer, 2019) Martín González, Osmel; Pérez Díaz, Noel; Cárdenas Ortiz, Rolando Pedro; Horvath, J.E.; Universidad Central "Marta Abreu" de Las Villas. Departamento de Física; Departamento de Astronomía, Instituto de Astronomía, Geofísica y Ciencias Atmosféricas (IAG), USP, Sao Paulo, Brazil; Cárdenas Ortiz, Rolando Pedro; Mochalov, Vladimir; Parra, Oscar; Martín González, OsmelSome basic principles to enlarge simple ecological models and the role of nonlinearities are discussed. The inclusion of internal groups and the new dynamic possibilities associated with this procedure are considered in the context of the logistic model. According to our results, processes like the success or extinction of a particular group without affecting the global population are not necessarily linked to the impact of environmental changes or the supremacy of a determined group or subspecies. In our case, the uniformity, the success or extinction of a particular group into a global population may be seen as the possibility to achieve or not a typical symmetry-breaking process. Such possibilities arise associated with the degree of nonlinearity contributions and the specificities of the interaction network in the model. Other elements linked with the ecological interaction, the role of symmetries and the phenomenological nature of ecological modelling are also discussed.
