By the end of this lecture, you should be able to: Describe the geographic template and how it influences species distributions. List and describe the factors of the geographic template that are most important in influencing the biota both in terrestrial and aquatic environments. Template: is the highly non-random, spatial variation of environmental conditions that forms the foundation for all biogeographic patterns. Relates to the differential heating and cooling of land and water. Land heats up quickly but also cools off quickly. Where the ne trade winds meet the se trade winds. Major deserts of the world are not randomly distributed, but tend to occur near 30*n or s latitude or along the leeward slopes of mountains eg sahara (30*) or mojave (leeward and jus over 30*) Organisms in aquatic environments are controlled primarily by temperature, light, water pressure, nutrients, and salinity. Nutrient upwelling zones in the ocean-correspond to circulation patter (eg california area)
