Part of the Ecological Studies book series (ECOLSTUD, volume 158)


Canopy gaps, created by tree-fall disturbances, greatly alter local microenvironmental conditions and the availability of resources for regenerating tree seedlings (Chazdon and Fetcher 1984; Bazzaz and Wayne 1994). These disturbance-induced local modifications in environmental conditions play a significant role in regulating the population dynamics and coexistence of forest species (see Chapter 7; Pickett 1983; Canham and Marks 1985; Denslow 1987).
