| Tiivistelmä: | The purpose of this paper is to demonstrate how conventional bioeconomic models of interspecific competition, such as the predator - prey model, are essentially special cases. Economic impacts imposed by the invader will depend on the exact nature of the interspecific interaction, and the correct measure of these impacts should be based on a comparison of the ex post and ex ante invasion scenarios. |
