  1. AP Bio. Ecology Podcast 4 Community Ecology – Coevolution and Coloration

  2. Community Ecology • Community • all the different organisms (species) that live together in a place Study to answer: In what way do the populations interact? Interspecific Interactions

  3. Many ways in which different populations interact: • Competition • Predation • Symbiotic Relationships COEVOLUTION – An overarching concept

  4. Coevolution • Evolution of one species in response to new adaptations that appear in another species • Examples • Prey defenses cause predators to adapt to them or die, etc. • All forms of symbiosis are examples of coevolution

  5. Camouflage Defense • Cryptic Coloration and Coevolution whipporwill insect lizard toad frog

  6. Mimicry and Coevolution • Warning coloration • Aposematic coloration • Two Types of Mimicry • Batesian • Mullerian

  7. Batesian Mimicry palatable or harmless species mimics a harmful model green parrot snake Hawkmoth larva puffs up to look like poisonous snake hawkmoth larvae

  8. Mullerian mimicry Mullerian mimicry two or more protected species look like each other cuckoo bee yellow jacket - group defense? - predators may evolve innate avoidance

  9. What kind of mimicry? Coral snake is poisonous King snake is not Red on yellow, kill a fellow; red on black, you’re okay Jack

  10. Batesianmimicry? Monarch male poisonous Viceroy male edible Which is the moth vs. the bee? Which is the fly vs. the bee? fly bee moth bee

  11. Common warning coloration • Aposematic species come to resemble each other black, red, orange & yellowmeans:DON’T EAT ME!

  12. Coevolution in Community • Predator-prey relationships • Parasite-host relationships • Flowers & pollinators Long term evolutionary adjustments between species
