Document Summary

Extra credit: correctly incorporate an appropriate statistical analysis into the method of our research proposal. Primary: the gradual establishment of communities of different species in lifeless areas where there is no soil in a terrestrial ecosystem or no bottom sediment in an aquatic ecosystem. The initial establishment and development of an ecosystem. Somewhat predictable stages from simple complex. Secondary: succession in an area in which natural vegetation has been removed or destroyed but the soil or bottom sediment has not been destroyed. The reestablishment of an ecosystem where there are remnants of a previous biological community. Allogeneic ( other origin ): succession is caused by an abiotic disturbance. Autogenic ( self origin ): succession is caused by a disturbance due to organisms within the system. Herbivore outbreaks (gypsy moth in oak forests, spruce budworm in spruce forests, army worm, etc), disease. Doesnt start from bare rock, there is still some herbaceous layer.
