Quantifying a dynamic risk landscape: heterogeneous predator activity and implications for prey persistence.
Spatial heterogeneity in predation risk can ameliorate impacts on prey populations, particularly for prey of generalists. Spatially heterogeneous risk implies the existence of refugia, and the spatial scale of those refugia and their persistence over time affect whether prey can avoid predation by aggregating therein. Our objective was to quantify the magnitude, spatial scale, and temporal pers...
متن کاملPersistence in a Generalized Prey-Predator Model with Prey Reserve
This paper deals with the study of a generalized prey-predator system with a reserve area. It is assumed that the habitat is divided into two regions, namely free zone and the other is reserved zone where predation is not allowed. The migration rate of prey population from free zone to reserved zone is predator density dependent. Predator functional response is considered as Holling type II. Bo...
متن کاملUniformly Strong Persistence for a Delayed Predator-Prey Model
An asymptotically periodic predator-prey model with time delay is investigated. Some sufficient conditions for the uniformly strong persistence of the system are obtained. Our result is an important complementarity to the earlier results.
متن کاملPersistence and stability of a two prey one predator system
The purpose of this work is to offer some mathematical analysis of the dynamics of a two prey one predator system in the presence of a time delay due to gestation. We derived criteria which guarantee the persistence of the three species and the global dynamics of the model system. Our study also shows that, the time delay may play a significant role on the stability of the system. Lastly, some ...
متن کاملPotential Landscape and Probabilistic Flux of a Predator Prey Network
Predator-prey system, as an essential element of ecological dynamics, has been recently studied experimentally with synthetic biology. We developed a global probabilistic landscape and flux framework to explore a synthetic predator-prey network constructed with two Escherichia coli populations. We developed a self consistent mean field method to solve multidimensional problem and uncovered the ...
