【 摘 要 】

Parental defence of offspring is an important thing during a predator attack in many species. A higher level of defence will save the offspring but in the other hand it also exposes a higher risk for parent. In this article, the authors try to construct the model for parental defence in prey population. The model based on stage structured dynamical model which assumed that the offspring are entirely dependent on parental care for survival. A contact between parent and predator describe as a distance, not a direct bodily contact. The dynamic and stability analysis are done here to predict the optimal level of defence. Furthermore, the simulation are shown to understand the behaviour of prey population with a certain level of parental defence. The simulation showed that parental defence is increase the survival rate of the offspring.
