Bio 112, April 26 2013 Transition for competition to other aspects with in populations. EVOLUTIONARY RACE TO ARMS!!!! Evolutionary Responses -Predator- Prey interactions -Defensive adaptations of prey lead to offensive adaptations of predators -coloration, speed, eye sight, its a back and forth between these populations. -Red Queen Hypothesis (Leigh Van Valen) -evolving as rapidly as they can but not going anywhere. Stay in the same positions in the food chain. -Plant- Herbivore Interactions -Passive defenses -Chemical defenses that plants have in place all the time. Toxic!!! bad taste. -Lower population, be a rare species. -be habitat colonizers, rapid growth and re-populate new areas only. -Physical defenses, such as thorns.
