Biodiversity of Western Rhodopes (Bulgaria And Greece): by Petar Beron

By Petar Beron

The current quantity of the sequence "Biodiversity of Bulgaria", treating the Western Rhodope Mountains, includes forty papers via seventy one authors. It starts off with a geographical define. It comprises normal stories of the Mycota (1,763 species of fungi), mosses (364 species) and algae (1,257 species, types and varieties) of the full Rhodopes. One paper each one issues the better flowers and the arboreal range of the Western Rhodopes. many of the contributions (34) deal with animal range, altogether contemplating 3,958 species of Rhizopoda, Nematoda, Oligochaeta, Acanthocephala, Cladocera, Calanoida, Copepoda, Syncarida, Amphipoda, Ephemeroptera, Coleoptera, Hymenoptera, Trichoptera, Diptera, Mollusca, Pisces, Amphibia, Reptilia, Aves, Insectivora, Rodentia, Lagomorpha and Macromammalia. for every of those better taxa, areas and teams vital for conservation, in addition to endemics, relicts, secure and endangered species are defined. The ebook is addressed to botanists and zoologists, conservationists, biogeographers, and all fans of the Balkan's nature.

STEFANOV In total, the Western Rhodopes mean annual radiation balance values have the following territorial distribution (VELEV, 1997, 2002): 1250-1500 MJ/m2 in the highest ridge parts (more than 1800-1900 m of altitude); 1500-1750 MJ/m2 in the Western and highest parts (above 1200-1300 m ); 1750-2000 MJ/m2 in the Eastern parts. Heat Balance If radiation makes the basic income into the heat balance, the outflow part includes several elements, namely the heat loss for evaporation from the Earth surface; the turbulent heat exchange and the heat flux from and to the bedding surface.

The possible solar radiation annual quantity (summary solar radiation at clear skies) is calculated from 8300 to 8800 MJ/m2 at the low and high mountain parts respectively. The real cloud conditions make these values 65-70% lower and they amount to 5500 MJ/m2 and 6000-6200 MJ/m2 respectively, while at the southern low parts in Greece this value reaches probably 6500 MJ/m2. In January the summary solar radiation is 230-250 MJ/m2 in the high mountain zones. In summer the solar radiation influx increases 3 times, reaching 2100 and 2200 MJ/m2 respectively.

In summer the solar radiation influx increases 3 times, reaching 2100 and 2200 MJ/m2 respectively. The value differences between the low- and high mountain areas are insignificant during the summer season. The lowest radiation values can be observed in locked mountain basins with less solar insulation, while the highest values hit the mountain southern parts. Mainly the Western Rhodopes geographic latitude determines these quantities. According to the existing data (LINGOVA, 1991) the annual solar radiation duration in the Mesta valley is about 2300 hours, while in Gorna Arda it is 2200 hours (2506 in Sandanski and 2439 in Athens).
