Coupling Demography, Physiology and Evolution in Chaparral Shrubs
Historically, since fire is a recurrent catastrophic disturbance, mediterranean-climate shrubs have been classified by their mode of postfire regeneration, i.e., obligate seeders, facultative seeders or obligate resprouters. While these terms are useful, they are too restrictive in that they only refer to a species’ response to fire and do not adequately describe modes of reproduction for all taxa.
