Document Summary
->when wolves declined, we see an increase in moose. ->after moose increased, sever winter, parasite moose ticks-->moose population dropped, then wolves population rebounded after that. ->acorns are the seed that comes from oaks. ->some years, a lot, some year, not a lot. Caribbean anolis lizards use of food resources on trees in caribbean. ->within each species, individuals of different sizes used different portions of their habitat. ->when different species were found next to each other on a tree or shrub, they tended to be species that differed in size (and morphology), so they consumed different foods and competed less tan they would otherwise. ->different species use different parts of the environment. Character displacement-->organisms can evolve, their characters can change, such that they are not competing for same resources over same amount of time. ->milkweed and all the insects that feed on the milkweed.
