Systems of possibilistic regressions: a case study in ecological inference.
Sergio Donoso, Nicolás Marín, M. Amparo Vila (2005)
Mathware and Soft Computing
This work introduces how possibilistic regression can be used in the case of non symmetrical triangular membership functions, building a system of regressions, so that suitable restrictions for each particular problem can be incorporated. We apply this methodology to the problem of ecological inference, in particular to the estimation of the electoral transition matrix. An experimentation with several examples shows the benefits of the new approach.
Temporally Interruptive Interaction Allows Mutual Invasion of Two Competing Species Dispersing in Space
Hiromi Seno (2010)
Mathematical Modelling of Natural Phenomena
With a reaction-diffusion system, we consider the dispersing two-species Lotka-Volterra model with a temporally periodic interruption of the interspecific competitive relationship. We assume that the competition coefficient becomes a given positive constant and zero by turns periodically in time. We investigate the condition for the coexistence of two competing species in space, especially in the bistable case for the population dynamics without dispersion. We could find that the spatial coexistence,...

Von Bertalanffy's growth dynamics with strong Allee effect
J. Leonel Rocha, Sandra M. Aleixo (2012)
Discussiones Mathematicae Probability and Statistics
Von Bertalanffy’s model is one of the most popular differential equation used in order to study the increase in average length or weight of fish. However, this model does not include demographic Allee effect. This phenomenon is known in the fisheries literature as “depensation”, which arises when populations decline rapidly at low densities. In this paper we develop and investigate new corrected von Bertalanffy’s models with Allee effects. The generalization that we propose results from considering...
