    MORPHOLOGICAL INVESTIGATIONS AND TRANSPLANTATION ATTEMPTS ON SOME ENDEMIC SPECIES OF NORTHERN CYPRUS
    Gücel, S; Yildiz, K
    The aim of this study was to investigate the morphology of 10 endemic taxa Pimpinella cypria, Ferulago cypria, Limonium albidum subsp. cyprium, Onosma caespitosum, Origanum syriacum var. bevanii, Salvia veneris, Sideritis cypria, Phlomis cypria var. cypria, Scutellaria sibthorpii and Teucrium cyprium subsp. kyreniae distributed in Northern Cyprus. These belong to the families Apiaceae, Plumbaginaceae, Boraginaceae, and Lamiaceae. All these species are distributed only on the Beshparmak mountains in the northern part of Cyprus and arc under a threat of extinction due to severe habitat degradation arising from human activities, forests fires and stone queries. The micrographs of the seeds were taken by means of trinocular stereo dissection microscope, and detailed morphological features recorded from the fresh and dried samples collected during 2001-2004. An attempt has been made for transplantation of these species to some protected sites.

    A PALYNOLOGICAL INVESTIGATION OF ENDEMIC TAXA FROM NORTHERN CYPRUS
    Yildiz, K; Gücel, S; Dadandi, MY
    Palynology of 19 endemic plant taxa belonging to 9 families distributed in North Cyprus was investigated by both light (LM) and scanning electron microscopy (SEM). The pollen grains were measured and their aperture characteristics and surface ornamentation determined. The systematic positions of the taxa as well as the genera they belonged to were investigated according to the data obtained. The largest pollen grains were found in Salvia veneris Hedge and the smallest ones in Onosma caespitosum Kotschy. The pollen type was generally termed trizonocolpate, pollen shapes spheroidal, prolate, subspheroidal, perprolate, supraprolate, pollen structure tectate and semitectate, and ornamentation scabrate, striate, microechinate, microperforate, reticulate, microreticulate, bireticulate, psilate and rugulate.

    New data on the East Mediterranean Nemesiidae (Aranei: Mygalomorphae)
    Özkütük, RS; Yagmur, EA; Elverici, M; Gücel, S; Altunsoy, F; Kunt, KB
    The paper contains new descriptions of Brachythele zonsteini sp.n. from Central Anatolia, Turkey, and Nemesia cypriatica sp.n. from Cyprus, as well as a redescripti on of B. varrialei (Dalmas, 1922), with the first description of the c onspecific female from Turkey. All descriptions are based on both sexes of each species and accompanied by images or diagnoses based on comparisons to related species.

    METAL BIOACCUMULATION BY BARLEY IN MESAORIA PLAIN ALONGSIDE THE NICOSIA-FAMAGUSTA HIGHWAY, NORTHERN CYPRUS
    Gücel, S; Koçbas, F; Öztürk, M
    Mesaoria plain is mainly used for agricultural purposes and contains 50 % of the barley fields in Northern Cyprus. The construction of a highway from Nicosia to Famagusta that passes through the plain has resulted in an increasing number of vehicles from 1997 to 2006, the majority of which run on leaded gasoline. Barley is cultivated on a large scale along the Nicosia-Famagusta highway, and was tested as a possible biomonitor for heavy metals. During the vegetative period, samples of barley plants and soil were collected at 4 distances (0, 50, 100 and 500 m) from the highway, at 4 sites, from January to April 2006. The highest concentrations of Pb++ (2.82 mu g g(-1)), Cd++ (1.52 mu g g(-1)), Cr++ (2.86 mu g g(-1)), Zn++ (51.8 mu g g(-1)) and Cu++ (19.8 mu g g(-1)) were recorded in soil collected beneath the highway, and the lowest in samples collected at 500 m from the highway, for Pb++ (0.54 mu g g(-1)) in the above-ground parts of barley, Cr++ (0.85 mu g g(-1)) in soil, and Zn++ (7.2 mu g g(-1)) in barley plant roots. A positive relationship was found between soil and plant heavy metal concentrations. According to the EU Directive 86/278/EEC on the protection of the environment and, in particular, of the soil, concentrations of Pb++ and Zn++ are below the threshold, Cd++ are between the limits and Cr++ are above threshold.

    New records of the East Mediterranean Lacbesana (Aranei: Zodariidae), with description of a new species
    Özkütük, RS; Yagmur, EA; Gücel, S; Shafaie, S; Özden, Ö; Kunt, KB
    A new species Lachesana bayramgocmeni sp.n. is described based on both sexes from Cyprus. The new species is compared in detail with L. blackwalli (O. Pickard-Cambridge, 1872). New data on the distribution of L. blackwalli in Turkey and Cyprus are presented.
