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 ...

The aim of this work is to study the temporal and spatiotemporal evolution of a threedimensional system that describes a predator-prey dynamics, where the predator population can develop an infectious disease. Thus, the ...

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 ...

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 ...

In this study specimens of three species of Characiformes predators were analysed: Salminus hilarii, Hoplias cf. malabaricus and Acestrorhynchus lacustris in order to verify the patterns in hunting strategies adopted by ...

A identificação de presas consumidas por predadores constitui-se em importante área da Ecologia por possibilitar o estudo das interações intra e interespecíficas em um ecossistema. Esse conhecimento ajuda a avaliar seu ...
