Description:
In PNAS, Allesina and Levine (1) proposed a game theoretical framework as a potential mechanism for biodiversity maintenance based on a network representation of competition. I observe four conceptual weak points within their model.First, the authors hypothesized that when two species come together, one wins and the other loses. In a zero-sum dynamics viewpoint, the authors simulated a (−1,0) interaction between two species. This is just a part of real-world interactions between species. Because each species can undergo three kinds of effects (positive, negative, or null) when interacting with others, a couple of species goes through nine possible combinations, where...
