Taxonomy, Ecology and Distribution of Juniperus oxycedrus L. Group in the Mediterranean Basin Using Bioclimatic, Phytochemical and Morphometric Approaches, with Special Reference to the Iberian Peninsula

Several studies have been conducted in the past to clarify various aspects of species genus Juniperus L. One critical group is oxycedrus L., especially from taxonomical point view. For this reason, we studied ecology, taxonomy and distribution taxa J. group. From an ecological standpoint, work use ombroedaphoxeric index (Ioex) explain presence populations ombrotypes that are not optimum for these taxa. The controversy over subsp. badia (H. Gay) Debeaux lagunae (Pau ex C. Vicioso) Rivas Mart. clarified, it accepted as a valid name, badia. phytochemical differences essential oils (EO) addressed their similarities analyzed; greater observed between badia, navicularis Gand. macrocarpa (Sm.) Ball. species. phytochemical, molecular allow Ball be maintained results obtained make possible establish rank which belong clear discrimination groups difficult interpret. Ecological, bioclimatic, morphometric us subordinate navicularis.
