The cloud forest in the Dominican Republic: diversity and conservation status

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. Rondeletio ochraceae-Clusion roseae (Ass. Cyatheo furfuracei-Prestoetum motanae; Ass. Ormosio krugii-Prestoetum montanae); and All. Rondeletio ochraceae-Didymopanion tremuli (Ass. Hyeronimo montanae-Magnolietum pallescentis; Hyeronimo dominguensis-Magnolietum hamorii). Due to human activity, some areas are very poorly conserved, as evidenced by the diversity index and the presence of endemic tree and plant elements. The worst conserved in terms of the relationship between characteristic plants vegetation (cloud forest) in areas with high rainfall in the Dominican Republic, along with its floristic diversity and state of conservation. Thanks to this study it has been possible to significantly increase the botanical knowledge of this important habitat.

Taxonomy, ecology and distribution of Juniperus oxycedrus L. group in the Mediterranean Region using morphometric, phytochemical and bioclimatic approaches.

The ecology, taxonomy and distribution of the Juniperus oxycedrus L. group of taxa are studied. From an ecological aspect, this work proposes a new ombroedaphoxeric index to explain the presence of populations of Juniperus in ombrotypes that are not the optimum for these taxa. The controversy among various authors on the taxonomy of the oxycedrus group with regard to J. oxycedrus subsp. badia and J. oxycedrus subsp. lagunae is clarified. The phytochemical differences in essential oils are addressed, and their similarities analysed; greater similarities are observed between oxycedrus and badia (H. Gay) Debeaux, and between navicularis Grand. and macrocarpa (Sm.) Ball. The phytochemical, molecular and distribution differences allow J. macrocarpa and J. navicularis to be maintained as species.
