predator model
1.This paper is devoted to study the following prey-predator system model with sparssing efffect. (The equation is abbreviated).
2.Existence of Positive Periodic Solution of a Ratio-Dependent Discrete Time Leslie Predator-Prey Model with Holling ⅢType Functional Response
4.This note studies two-species metapopulations dynamics com mon model considering of the affect of interspecific interaction to colonization and extinction rate and rescue effect,demostrates the conditions of two specie s capable of coexistence in the competitor,predator-prey or mutualist system.
