title: Coexistence of similar zooplankton species by differential adaptation to reproduction and escape, in an environment with fluctuating food and enemy densities. I. A model.
abstract: A model is presented explaining the coexistence of similar planktonic species that compete for identical food resources and are exposed to identical enemies. The model is based on alternative adaptations of the competitors to reproduction and escape, in an environment that fluctuates with respect to food and enemy densities. Seasonal fluctuations of food and enemies may lead to seasonal segregation of the competitors. Indifferent and stable equilibria are discussed, including the role of abundance-dependent selectivity by predators.
