Document Summary
Determined by temp + rainfall (also determines types of plants that grow) Height, density, species diversity decreases from warm wet climates to cool dry climate. Raukiaer; classified plants based on trains that varied with climate. Location of prennating organ- tissues that give rise to new growth the following season, sensitive to climate conditions. Life form spectra are more alike in similar climates on diff continents than they are in diff climates on same continent. Where: areas centered on the equator (c + s, am = ea"s) Climate: little seasonal variation high yearly rain + relatively constant warm temp. Emergent layer tall trees (40m+), overstory of trees up to 30 m, subcanopy of trees and tall shrubs, and ground layer of herbaceous veg. High despite heavily leached, nutrient poor soils becuz litter decomp fast + rapid nutrient uptake from mycorrizhae est. to have over half of the terrestrial species on ea.
