Ecological and Syntaxonomic Analysis of the Communities of and () in the European Mediterranean Area.

Nitrophilous communities dominated by and in the European Mediterranean area were studied. The nomenclature was corrected according to the current taxonomy, following the International Code of Phytosociological Nomenclature (ICPN). The statistical analysis revealed six new associations and one subassociation, with four in Spain, one in Greece, and one in Italy.

Phytosociological Study, Diversity and Conservation Status of the Cloud Forest in the Dominican Republic.

The study of the forest in rainy environments of the Dominican Republic reveals the presence of four types of vegetation formations, clearly differentiated from each other in terms of their floristic and biogeographical composition, and also significantly different from the rainforests of Cuba. This leads us to propose two new alliances and four plant associations located in northern mountain areas exposed to moisture-laden winds from the Atlantic: All. - (Ass.

Morphometric analysis and bioclimatic distribution of s.l. (Asteraceae) in the Mediterranean area.

We present a revision of in the Mediterranean area based on: a) micro-morphology of the disc floret cypselas observed with a high-resolution confocal microscopy; b) measurements of the disc cypsela with a stereoscopic microscope - duly scaled; c) its distribution in several bioclimatic belts; d) field observations; e) comparisons of herbarium samples. Because of this study, we propose the elevation of Glebionis coronaria var. discolor to the rank of species, as , based on morphological and ecological characteristics such as the disposition of the intercostal glands, the size of the disc cypsela wings and its distribution according to the bioclimatic belts.
