摘要
Tipping points have been shown to be ubiquitous, both in models and empirically in a range of physical and 生物 systems. The question of how tipping points cascade through systems has been less explored and is an important one. A study of noise-induced tipping, in particular, could provide key insights into tipping cascades. Here, we consider a specific example of a simple model system that could have cascading tipping points. This model consists of two interacting 族群s with underlying Allee effects and 隨機 dynamics, in separate patches connected by dispersal, which can generate bistability. From an ecological standpoint, we look for rescue effects whereby one 族群 can prevent the collapse of a second 族群. As a way to investigate the 隨機 dynamics, we use an individual-based modeling approach roote
