Lecture 34 1) Dispersal is key for plants because they are stationary and they don’t want to compete in the same locus. 2) Fleshy fruits are eaten by dispersers (reward) and does not support the embryo (seed). 3) Plants must defend themselves against enemies – Spines, thorns, hairs, toxic chemicals (any spices like basil mint or oregano), poison ivy, Mimicry – plants hide from potential predators, mutualistic reactions with animals that protect plant (ants). a) Acacia - Ants eat the nectar produced by the plant, trim its leaves – plants provide protein for larvae at the end of its leaves, live in its hollowed-out thorns, etc. Symbiotic, protect plant from predators and even rival plants. 4) Ecological interactions between plants and organisms can lead to evolutionary changes (hummingbirds have long beaks to eat from long narrow flowers).

Unformatted text preview: 5) Lab Projects Behavioral Ecology 6) Skipper Larval Behavior a) Build shelters out of their leaves (fold over and hold down with silk), and they eject their shit far away from themselves. Could be for hygiene, crowding (dont want poop all around), and natural enemies (poop gives olfactory cues). The first two are inconsequential, the natural enemies is the one (wasps are attracted to skipper poop). 7) Color learning in butterflies a) Have innate color preference but can also learn colors. Monarchs orange was their favorite color. b) After giving a reward for each blue (only 1 min per day) they fixed quickly for blue. Can change again very very quickly (turnover like 4 days). 8) Memory retention in moths Moths can remember what they learned as caterpillars. (odor association with an electric shock)...
