Document Summary

Biome: a group of terrestrial ecosystems around the world that are similar in vegetation structure (physiognomy), and are common in their adaptations to environmental conditions. Ecotone: a transitional zone from one biome to another biome. Ecosystem: a functional system that includes an assemblage of interacting organisms (biotic) and their environment (abiotic). Community: an assemblage of organisms characterized by a distinctive combination of species that co- occur in space and time. Dispersal: seeds are distributed by water, air, animals. Dispersal refers to how seeds will get from one class to another. Colonization: following dispersal, colonization is what occurs when a species successfully establishes as a population in an area. It can be local or global and caused by environmental fluctuations, change events in a small population, or major environmental impacts. Ecological tolerance: the temperature regime suitable for a species to survive. Niche: total environmental ecological requirements for a species and the role that it plays in an environment.
