BI111 Chapter Notes - Chapter 46: Superorganism, Insular Biogeography, Climax Community
Document Summary
Batesian mimicry occurs when a palatable or harmless species resembles an unpalatable or poisonous one. Mullerian mimicry when two or more palatable species look the same to reinforce lessons learned by a predator that attacks any species in the mimicry complex; relies on aposematism: warning signals. The range of conditions and resources a species actually use in nature fundamental niche, interactive hypothesis, individualistic hypothesis, ecotone, trophic level, keystone species, succession, climax community. Describe the types of population interactions and their effects (also see section 46. 4) Effects on interacting populations: +/- ; predators gain nutrients and energy while prey are killed or injured. +/- ; herbivores gain nutrients and energy; plants are killed or injured. / - ; both competing populations lose access to some resources. +/0; one population benefits while the other is unaffected. +/- ; parasites gain nutrients and energy while the hosts are injured or killed.
