WebEcologists found that the cycle could be explained by interactions between the lemming and four predators: the owl, fox, skua—a bird—and stoat. The owl, fox, and skua are opportunistic predators that can use various food sources and tend to eat lemmings only when they are abundant. ^ {7,8} 7,8 The stoat, in contrast, eats pretty much only lemmings. WebMathematically, we can achieve this by incorporating a density-dependent term into the population growth equation, where K represents carrying capacity: Now, the equation shows population growth rate r modified by the (K–N)/K term.
