Document Summary

Mode of existence trees lianas shrubs herbs bryophytes epiphytes perennial perennial perennial perennial and annual perennial perennial. There are taller trees in the understory because of more life. There are six principle biomes: forest, savanna, shrubland, grassland, desert, tundra biomes are further divided into formation classes. Vegetation characteristics = f ( cl + o + r + p + t) Cl = climate (energy and water = water balance) O = organisms (litter + bacteria + (other decomposers) > nutrients) P = parent material or geologic substrate (rock) that is the basis of soil. Cl = climate and soils = factors responsible for general similarities in vegetation and sub-continental or regional scales = biomes and formation classes. Orpt = local scale factors which cause variation between sites = habitats. Global climate determines biomes and formations: classified based on temperature and moisture. Forest biome: low-latitude rainforest, monsoon forest, subtropical evergreen forest, mid-latitude deciduous forest, sclerophyll forest, needle-leaf forest.
