Document Summary
Geob 102 - our changing environment: climate and ecosystems - lecture 23: growth models/communities and ecosystems. Population growth when introduced to a new environment with unlimited resources. Deer in kaibab plateau (arizona): an extreme case of rapid population growth and decline due to human intervention. Under natural conditions, populations tend to increase to a relatively constant abundance, determined by the carrying capacity. *communities putting species that live in the same area together. Species compositions: list of all species that exist at a location (can be classified into plants, mammals, insects, etc. ) Formation: community with a specific vegetation structure (e. g. treeless tundra, mixed deciduous forest, etc. ) Life form: applicable to plant physiognomy (e. g. perennial/annual, land/aquatic) Growth form: trees, shrubs, herbs, epiphytes (non-parasitical upon another plant), lianas (woody vines) and bryophytes (non-vascular [cell to cell]) Distribution of communities in space based on topography and soils (toposequence) Vegetation defines everything - transform suns energy to plants that animals can eat.
