Source–sink impulsive bioeconomic models: Seasonal closures with fixed length
; ; Cordova-Lepe, Fernando (2011)
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 ...
