Review for Quiz 4 Key terms: You should be able to explain each term or idea and give examples (if applicable). It is important to know the significance of these terms and their context in evolutionary biology. Community ecology Limited resources Competition Parasite-host Predator-prey Mutualism Commensalism Amensalism Competitive exclusion Fundamental niche Realized niche Interference competition Exploitative competition Brood parasitism Evolutionary arms race Primary defenses Secondary defenses Crypsis Homotypism Chemical defenses Batesian mimicry Mullerian mimicry Self mimicry Symbiosis Review questions : 1. Make a chart of the 5 types of ecological interactions, being certain to include how the interaction affects both participants. Give an example of each type of interaction. 2. Compare and contrast mutualism (ecological interaction) and cooperation (social act). 3. What is the difference between a species' fundamental niche and realized niche? Which represents a larger niche size? Under what circumstances would they be the same?

Unformatted text preview: 4. Co-evolutionary arms races are common in ecological interactions. Describe how arms races may evolve in the context of Batesian mimicry, Parasite-host interactions and Predator-prey interactions. 5. There are two major types of defenses: primary and secondary. Describe the differences between these two types and give several examples of each. 6. How can a single organism be involved in both Batsesian and Mullerian mimicry, and how would each affect that organisms phenotype relative to the mimic over time? 7. Describe how predator-prey and parasite-host interactions are both similar and different. 8. Describe some adaptations of brood parasites (e.g., cuckoos and brown-headed cowbirds) and the defenses of songbird host. 9. Provide examples of mutalisms that have evolved in termitesprotists, animalanimal and plantanimal. In particular, describe how each species benefits from the interaction....
