The brown howler monkey (Alouatta guariba clamitans) is a species threatened with extinction. In an area belonging to the Brazilian army located in the state of Rio Grande do Sul, Brasil, where the highly fragmented ...

In this work, we formulated four discrete prey-predator models to analyze the effects of Functional Response on the dynamics and spatial distribution of preys and predators. We consider that, in the absence of the predator, ...

In this work we propose a discrete-time model, composed by a system of di erence equations to represent the dynamics of interaction of the velvetbean (Anticarsia gemmatalis) and the entomopathogenic fungus Metarhizium ...

In this work, we propose a Coupled Map Lattices model to analyze the dynamics of an insect-pest in intercropping of a main culture (target of the herbivore) with a secondary culture that presents antibiosis resistance ...

Genetically Modified Organisms (GMOs) are organisms that have undergone artificial changes in their genetic material. We can cite as an example of GMOs, genetically modified crops or, simply, transgenic crops. The main ...
