BIO 182 Lecture Notes - Lecture 31: 50Th Parallel North, Temperate Coniferous Forest, Rain Shadow
Document Summary
Biomes broad spaces that have similar communities. Climate average weather patterns: hotter at the equator, angle of axis creates seasons, axis also creates less direct sunlight during spring and fall. Warm air rises and spreads to the poles where it cools and falls and spreads back towards the equator. Plants on one side of the mountain will be large and the other side will have smaller plants because of the rain shadow. Evapotranspiration combination of evaporation from bodies of water and transpiration from plants. Earth would be hotter without oceans because they distribute and absorb heat and create rain and clouds. Plant convergence develop similar traits in similar habitats even though they"re unrelated. Very few plants that are mostly small. Permanent ice beneath small layer of dirt: alpine. More temperature variation than tundra and no permanent ice. Deep, rich soil and slow decomposition: temperate coniferous forest. Large conifers with fern and blueberry undergrowth. More animal diversity than taiga: deciduous forest.
