x alternative stable states
o Different community development scenarios that are possible at the same location
under similar environmental conditions.
x climax stage
o The final stage of succession, viewed as a stable end point that experiences little
change.
x disturbance
o An abiotic event that kills or damages some organisms and thereby creates
opportunities for other organisms to grow and reproduce.
x hysteresis
o An inability to shift back to the original community type, even when the original
conditions are restored.
x pioneer stage
o The first stage of primary succession.
x primary succession
o Succession that involves the colonization of habitats devoid of life. Compare
secondary succession.
x secondary succession
o Succession that involves the reestablishment of a community in which most, but
not all, of the organisms have been destroyed. Compare primary succession.
x stable
o Returning to the original state after some perturbation.
x stress
o An abiotic factor that results in a decrease in the rate of an important

o The change in species composition over time as a result of abiotic and biotic
agents of change.

Document Summary

N alternative stable states: different community development scenarios that are possible at the same location under similar environmental conditions. N climax stage: the final stage of succession, viewed as a stable end point that experiences little change. N disturbance: an abiotic event that kills or damages some organisms and thereby creates opportunities for other organisms to grow and reproduce. N hysteresis: an inability to shift back to the original community type, even when the original conditions are restored. N pioneer stage: the first stage of primary succession. N primary succession: succession that involves the colonization of habitats devoid of life. N secondary succession: succession that involves the reestablishment of a community in which most, but not all, of the organisms have been destroyed. N stable: returning to the original state after some perturbation. N stress: an abiotic factor that results in a decrease in the rate of an important.
