Environmental Stresses and Inherent Limitations Affecting CO2 Exchange in Evergreen Sclerophylls in Mediterranean Climates

  • E. Lloyd Dunn
Part of the Ecological Studies book series (ECOLSTUD, volume 12)


For several years we have been investigating the adaptive physiological basis for convergent evolution of the evergreen sclerophyllous shrub form in mediterranean-type climates. The objectives of this discussion are twofold. First, it is necessary to summarize briefly the results of the field studies designed to measure the effects of environmental stresses characteristic of mediterranean-type climates on the seasonal metabolic activity of evergreen shrubs growing under natural conditions in California and Chile. Second, the results of laboratory studies intended to analyze the inherent limitations of the photosynthetic capacity in these species, and the basis of some of the observed field responses, is reported.
