The repartition of aconitum species throughout the Romanian Carpatians
26-28Views:52Due to anthropic factors, the spreading of the Aconitum species has known a significant reduction in the last decades, the main causes are represented by the diminution of the natural area, and by the intensive harvesting of some species for pharmaceutical purposes. All Aconitum species are distinguished by a great variability, probably as a result of hybridization, but generally they do not fit into an easy to recognize morphologic or geographic pattern. This remarkable polymorphism, underlined by the specialists in the field, is responsible for the taxonomic complexity of the Aconitum genus and results in different classification ways of the pertaining species. Thorough future chemotaxonomic researches are necessary to establish the exact place of each species in more and more complex classifications.
From the species of the investigated genus, the widest spreading has Aconitum anthora, followed by A. moldavicum and A. paniculatum. The areas richest in different Aconitum species are the Northern half of the Oriental Carpathians and the Eastern part of the Southern Carpathians; in the Apuseni Mountains, Aconitum appears less frequently. -
The vegetation of the pastures from the Aninei mountains
23-25Views:54The situation of the Aninei Mountains in the South-Western part of Romania, at the interference of air masses with maritime (of Western origin), continental (of Eastern origin) and Southern character (coming across the Mediterranean Sea), as well as the carstic relief conferred by the calcareous geologic substrate, account for the floristic peculiarities of this region, containing numerous rare and characteristic Banatian elements. The European, Southern and Eastern influences are expressed in the diversified floristic composition of the pastures, where xerophile and xeromezophile species prevail. A pecularity of the researched area is represented by the calcophile vegetation of the xerophilic pastures. In the floristic composition, we were able to identify several sporadic species in Romania.
