Document Summary

Genetically based, reciprocal adaptations in species that interact ecologically: predation, herbivory, competition, commensalism, mutualism, parasitism. 1980- canine parvovirus outbreak (deadly infection in wolves) which is why the population decreased suddenly (huge drop) -> lead to huge increase in moose population. Butterflies and frogs have different appearances to hide from prey, have certain appearances is not targeted by predators therefore it is a benefit to certain prey to mimic the appearance. Intermediate disturbacen hypothesis: not many k selected psiecies, found that highest species richness at intermediate values. Fac as each species colonized they make the environment more favourable for later species. Inh species are holding on and don"t want to be replaced, not making it easier for later species.
