Document Summary

S3- animals disperse when their reproductive value is at peak. S4- vanilla seeds: tiny seeds (like dust), coconut- biggest seeds, differ in 7th order magnitude from vanilla seeds. S6- a seed is going to have the highest success b its size, the larger the seed, the more maternal material enough resourcesgreatest success in survival. Tiny seeds don"t have the same resources, so must land in places good for sporutong. S8- berries, attractive to animals to eat seed dispersal. Birds smaller intestines only need to break down simple fuit sugars, and brightly coloured. Apple seeds covered by cyanide (bad- tasting so we don"t eat it). Birds and bats are great dispersers -> fly and take seeds along the way. elaiosome(what ants eat) on seeds, then the seed is just disposed by ants. Glacier lily (enthronium grandiflorum) concentrated in one type of habitat, where there is a lot of superficial rock.
