Source–sink impulsive bioeconomic models: Seasonal closures with fixed length
The dynamics of four source–sink models for an exploited resource under a constant fishing effort are here presented. Two models are described by ordinary differential equations; the other two are expressed by impulsive ...

Stability analysis of a self-cycling fermentation model with state-dependent impulse times
A self-cycling fermenter is a batch fermenter subject to recurrent emptyings of liquid volume followed by the refilling withnew fresh substrate. This article construc ts a modified model of self-cycling fermenter, which ...

Susceptibility to organophosphates pesticides and the development of infectious-contagious respiratory diseases
In this paper we develop an SIRS compartmental model to investigate the dynamic interplay between pesticide intoxication and the spread of infectious-contagious respiratory diseases. We are particularly interested in ...

The process of connectivity loss during habitat fragmentation and their consequences on population dynamics
Understanding the processes and consequences of habitat fragmentation is highly relevant since it represents a serious threat to biodiversity. However, fragmentation includes several facets that are difficult to dissect, ...
