Papp, Beáta; Sabovljevic, M.: Contribution to the bryophyte flora of Turkish Thrace

MATERIALS AND METHODS Collections were made in May of 2000 by Beáta Papp (BP) and Marko Sabovljevic (BEOU). Materials are deposited in those two herbaria. Most of the important montane areas were visited and different habitat types were investigated. In our enumeration the nomenclature for the mosses follows CORLEY et al. (1981), CORLEY and CRUNDWELL (1991), and for the liverworts follows SCHUM ACKER and VAN A (2000). Exceptions are the subspecies and varieties and some Tortula and Hypnum species, where we based our identifications and nomenclature on the works of KRAMER ( 1980), SMITH ( 1991, 1993, 1997), FREY et al. (1995), BLOM (1996) and CORTINI PEDROTTI (2001). To establish the European distribution types in the floristical evaluation, we followed DULL (1983, 1984, 1985, 1992). THE INVESTIGATED AREA Turkey has a peculiar situation as it belongs to the southeastern European countries, the Balkan countries and to southwestern Asian countries at the same time. Turkish Thrace is part of Europe and the Balkan Peninsula in its southeasternmost part. It is a region between Greece and Bulgaria, edged by the Aegean, Marmara and Black Seas. The European part of Turkey covers 9,250 square miles. Turkish Thrace is topographically, climatically and biologically heterogeneous. The region bordered by the Black Sea (Istranca or Yyldyz daöTary) is composed mainly of schist and represents a low continuation of the northern mountain range of Anatolia. The central part is occupied by undulating plains drained by the Ergene River. On the northwestern side of the Marmara Sea (which divides Europe from Asia) there is a low sandstone range, the Ipyklar daőyor Tekir daőlari which continues southwards into Gelibolu (Gallipoli) peninsula (DAVIS 1965). The climate of Turkish Thrace is typical Mediterranean near the southern coast. Mild, wet winters and long, hot, dry summers are characteristic. Drought period is usually from May to September. There is a clear difference from west to east of Thrace. The climate is more humid and cooler going towards the Black Sea coast or to the north of the area. Turkey is a meeting point of three phytogeographical regions: Euro-Siberian, Mediterranean and Irano-Turanian. In the European part of Turkey (Turkish Thrace) the Euro-Siberian region is present in a narrow strip along the Black Sea coast. The relatively humid climate is shown by the predominantly mesophytic vegetation. There is, however, an interrupted chain of Mediterranean enclaves (mainly consisting of sclerophyll scrub), that also extends along the Black Sea
