Exercise 17

In his experiments on competition between T. confusum and T. castaneum, Park (1954) found that one species usually excluded the other species but that the outcome depended upon physical conditions. In which circumstances did T. confusum have the competitive advantage? In which circumstances did T. castaneum have the competitive advantage? Could Park predict the outcomes of these experiments with complete certainty? What does this suggest about competition in nature?
