Opis

Clusia is the only dicotyledonous tree genus with crassulacean acid metabolism (CAM), and in some cases all variants of CAM can be expressed in one given species. These unique features as well as Clusia's extreme flexibility have put it in the limelight of international research. The studies presented in this volume embrace anatomy, morphology and plant architecture, phytogeographical distribution and community ecology, phylogeny and genetic diversity, physiology and metabolism, physiological ecology and functional diversity, circadian rhythmicity and biological timing. Covering all aspects of tree biology, this richly illustrated volume is an invaluable source of information for any plant scientist.
