The specie has the age structure, including the juvenile stage and adult stage, the other specie remains unstructured. This paper studies the stability and permanence of the Juvenile/Adult Ricker competition model. Using Lyapunov exponent we analyze the dynamic behaviors of this model, and obtain the existence of the multiple mixed-type attractor which explains the multiple mixed-type attractor phenomenon that found in the lab by Park.
