Аннотация:The review summarizes and systematizes the results of existing experimental studies on the presence of CAM (Crassulacean Acid Metabolism) in vascular epiphytes of South and Central America, Southeast Asia, and Australia. This group of plants, despite its diverse taxonomic composition, exhibits common features in the distribution of carbon isotopic signature values (δ13C), which is associated with the wide distribution of CAM variants. Based on the analysis of data from the literature, we collected about 2000 δ13С values of vascular epiphytes. Based on the rich experience of studying individual floras and taxa of epiphytes, we are trying to give a current global picture of the distribution of CAM among epiphytes.
