Document Summary
The study of distribution and abundance (where are the organisms and how many of them are there) How organisms interact with environment (competition, predation, etc. ) Why don"t bananas and birds of paradise live in buffalo. Why mountain lions in na but other lions in africa: evolution and ecology are intimately connected volcanic activity -> galapagos. Gene flow climate, competition, mates, hybridization -> ecological changes now affect the evolution later: two parts of the environment, biotic (living part, abiotic (non-living part) Climate is controlled by three factors: variation in light intensity. Equator is warmest b/c area hit by beam of sunlight is smaller at equator than it is closer to the poles = same amount of sunlight is more concentrated at the equator. > light has to go through shorter path thru atmosphere to get to the ground of the equator -> atmosphere that it"s going through reflects sunlight re-radiates back. Hotter at the equator, cooler at the poles.
