By Petar Beron

The current quantity of the sequence "Biodiversity of Bulgaria", treating the Western Rhodope Mountains, includes forty papers through seventy one authors. It begins with a geographical define. It contains basic studies of the Mycota (1,763 species of fungi), mosses (364 species) and algae (1,257 species, types and varieties) of the whole Rhodopes. One paper each one issues the better vegetation and the arboreal range of the Western Rhodopes. lots 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, safe and endangered species are defined. The e-book is addressed to botanists and zoologists, conservationists, biogeographers, and all fanatics of the Balkan's nature.

Flüchten oder Bleiben? Rekonstruktion biographischer Verläufe und Ressourcen von Emigranten im Nationalsozialismus

Sylke Bartmann zeigt anhand der Rekonstruktion biographischer Verläufe von Emigranten unterschiedliche Umgehensweisen mit dem Nationalsozialismus und damit verbundene Repressalien und Bedrohungen auf. Der Fokus richtet sich dabei auf den Einzelnen als Akteur und Gestalter seines eigenen Lebens. Es wird die Frage beantwortet, inwieweit in den Prozessen der Biographisierung Ressourcen zum Ausdruck kommen, die das Leben im Nationalsozialismus (weiterhin) als zusammenhängend und sinnvoll erscheinen lassen - auch wenn dem einzelnen Menschen die Welt manchmal sinnentleert gegenüberzustehen scheint.

Example text

Animals inhabiting the Rila-Rhodopes region are basically of Holarctic, Paleoarctic, Euro-Siberian and European types. This region is distinguished for the big number of relict invertebrates (25 taxa in the Western Rhodopes) and high endemism (endemic animals are twice more in the Western Rhodopes and they are quite different from those in Rila and Pirin). The Western Rhodopes southwestern slopes, which are included into the Struma-Mesta zoological region make a habitat of a multitude of animal types of subtropical, Iran-Turanian and Mediterranean origin, as their relative share increases to the south towards Greece.

Everywhere river valleys determine the wind directions. Mountainvalley winds occur and they are typical local climatic features throughout the warm season. Quiet weather is most often observed in inner mountain basins. These are periods of quick cooling, bringing temperature inversions. Big dams in the Western Rhodopes also have some climatic influence, but it involves only coastal areas and affects some local climatic elements causing higher humidity, higher frequency of fogs and lower temperature amplitudes.

Experimental research about the radiation regime of mountains (LINGOVA, 1991) show that direct solar radiation increases with altitude with a mean gradient of 0,014 kW/m2 for each 100 m. Until about 600-800 m the summary solar radiation is determined by the local microclimate and basically by the cloud regime. The altitude influence starts above this level and experimental data shows that increase gradient of summary annual radiation becomes 29 MJ/m2 for 100 m in average. In winter, when mid-mountain and especially high mountain areas are above the low clouds, solar radiation income is much more, compared to low-mountain and mountain outskirt areas.
