A characteristic feature of living organisms is that they respond to the environment in search for food and reproductive opportunity. In particular, predators can move towards high prey density, which is called prey--taxis. In this talk, we present how a prey-taxis model can be derived using a modified Kareiva-Odell approach and a parabolic limit. An alternative derivation of a prey-taxis model is also outlined based on a model with resting stages. Subsequently we consider an application of a prey-taxis model: a role of prey-taxis on spreading prey population. We find that prey--taxis alone does not slow prey spread although it does in the presence of an Allee effect for the prey. A brief introduction of previous research experiences and future plans would be followed.
