Disturbance resource boosts are transient pulses that pioneer traits exploit

Evidence

An important feature of any increase in resource availability produced by a disturbance is its transient nature. As biomass is reestablished at a site, the relative availability of resources for future colonists will, in general, decline. Tilman (1982) has presented an analysis of plant competition for levels of resources available when the rate of uptake by an intact community has equilibrated with the rate of supply of a resource. The transient pulses of resources produced by many natural disturbances represent a distinctly different pattern to which plant species can respond. Traits traditionally associated with the response of woody plants to disturbance (e.g., rapid growth rates, small sizes, and early reproduction) appear to facilitate the exploitation of such pulses of resources. — S.
