Um modelo para controle biológico de pragas associado ao uso de pesticidas
(Universidade Federal de Santa Maria, 2014-04-10)
In this work we propose a Coupled Map Lattice to study a predador-prey system where
the prey is a pest and the predador is a biological control agent. We consider that the
strategy of biological pest control is combined ...
Múltiplas escalas em interações presa-predador
(Universidade Federal de Santa Maria, 2010-03-05)
The main purpose of this dissertation was to analyze the occurrence of two time scales in predator-prey systems. Initially, we proposed two discrete models without
spatial structure. The first model considers fast vital ...
Perseguição e fuga em modelos presa-predador
(Universidade Federal de Santa Maria, 2010-03-04)
The main purpose of this dissertation is to propose and analyze the effects of pursuit and evasion on predator-prey spatiotemporal dynamics. We use a Coupled Map Lattices formulation in which a system of difference equations ...
Bifurcação de Turing-Hopf em um sistema presa-predador
(Universidade Federal de Santa Maria, 2012-06-04)
In this work we studing a generalized predator-prey system in a spatial domain, in
terms of formation. We show parameter, regions where transcritical, Hopf and Turing
bifurcations appear are presented, and also some ...
Modelos de redes de mapas acoplados para interações herbívoro-predador
(Universidade Federal de Santa Maria, 2013-04-12)
In this work we propose a discrete predator-prey model with the purpose of analyzing the
spatio-temporal dynamics of herbivorous and their predators. For that, we explicitly consider
the dispersion of both species through ...
