Theoretical and applied studies on predator-prey interaction

Abstract

Abstract: Population interaction between predator and prey is one of the central subjects of study on animal population ecology for a long time. There are three major types of study. The first is theoretical. Here various mathematical models have been constructed to simulate the behaviour of interacting predator and prey population. The second is experimental, in which, properties of actual predator-prey population systems are compared with theoretical models. The third is represented by field investigation, in which, naturally occurring interactions between predator and prey are analysed in the light of various principles derived from theoretical and experimental types of study. In the field of applied ecology, there have been many attempts to achieve the biological control of pests by introducing new and more effective natural enemies into their natural or semi-natural population systems, sometime having attained the goal, and sometimes ended in failure. These attempts can all be regarded as field experiments on predator-prey interactions in the real world.
