Document Summary
Abiotic factors: climate: global climate, regional climate, microclimate. Global climate change: greenhouse effect , the data, impacts. Physical factors drive the distribution of organisms at the global scale: light, temp, precipitation. What drives global climate: the sun (particularly to the tropics, movement of the planet, atmospheric and oceanic circulation. Coriolis force: middle of sphere moves fastest while spinning, skinny = slow, fat = faster, deflection in opposite direction of spin. Ocean circulation: large scale gyres (current) are driven by coriolis forces, shallow currents driven by prevailing winds, can have massive impact on climate, el ni o southern oscillation (2-7, weaken or stop tradewinds. Regional climate: landmasses (heat faster than oceans, monsoons, land-sea breeze. Why do we give a shit: so populations can survive. Population ecology: density/dispersion, the study of births, deaths, and the dynamics forces which regulate a population, spatial. Density the number of individuals per unit or volume.
