SUCCESSION

Which one defines climax community?

A climax community, in the traditional succession concept, is a relatively stable, self-perpetuating assemblage that maintains its broad composition under the prevailing climate and soil conditions. Long-lived organisms reproduce successfully within the community, nutrient cycles are comparatively tight, and small population changes do not automatically reset succession. This does not mean the community is motionless: individuals die and recruit, species abundances fluctuate, and patches are created by local disturbance. Nor must it have the highest primary productivity; mature biomass carries

SUCCESSION

During succession, the climax community is characterized by:

A mature or conventionally defined climax community has high standing biomass and relative stability because long-lived organisms and complex trophic interactions dominate after prolonged succession. Plants accumulate woody tissue and extensive roots, while soils store organic matter and nutrients. Gross primary production may remain substantial, but community respiration also becomes large because the accumulated biomass must be maintained. Net ecosystem production therefore approaches a lower value than in rapidly growing earlier stages. Stability here means persistence or recovery around a
