Can there be more predators than prey?

摘要: The theorem that there can be no more species in a habitat than the kinds of resources on which they depend is discussed. It shown two predators limited by different stages life cycle same prey species, and herbivores if parts plant. This leads to question, what circumstances measurable quantities, x1 x2, regarded as for purposes theorem, it functionally dependent so knowledge one value at any time specifies other, then are resource, but otherwise act resources, even highly correlated. variables such climate invading not themselves influenced densities limited, irrelevant determining number or limiting factors present.
