Shifting Mosaic Metapopulation Dynamics
Growth-dependent thinning: Thinning rates at local scales (100 to 102 m2) are determined by growth rates. There is no “carrying capacity” at such scales in the traditional sense, because plants are continually growing and, therefore, thinning.
Changing importance of density-dependent and density-independent mortality: The relative importances of different mortality risks change with canopy coverage, and they influence recruitment. Thinning caused by crowding has different demographic consequences than do juvenile death and senescence.
Episodic recruitment: Seedling establishment is locally episodic, being associated with “disturbance”, i.e. specific types of mortality.
