    Ethnoecology of poisonous plants of Turkey and Northern Cyprus
    (Pakistan Botanical Soc, 2008) Ozturk, Munir; Uysal, Ismet; Guecel, Salih; Mert, Tuba; Akcicek, Eren; Celik, Sezgin
    Interest in plants is increasing and much work is being carried out these days on their multipurpose uses. A great impetus has been given to this during the last 3 decades. Several publications have been made by different investigators. Large number of naturally growing plants are collected and sold at the markets. Nearly 500 plants are used for primary health care in Turkey and a 23 in Cyprus. However, not much is known about the poisonous plants. Some of these are toxic and others cause reaction. Plant poisoning lies around 6%, rurals suffer more from the consumption of naturally growing plants as compared to urban dwellers. One has to be very cautious before using these plants as the plants used for the purpose of treatment of diseases as a whole or parts thereof or consumed by the public directly could prove dangerous for the health. This paper describes ethnoecological aspects of the widely distributed major poisonous plants in Turkey and Northern Cyprus which can prove fatal if used unknowingly. Major applications and active constituents of plant taxa are outlined.

    Morphology, anatomy, ecology and palynology of two Centaurea species from Turkey
    (Bangladesh Botanical Soc, 2008) Celik, Sezgin; Uysal, Ismet; Menemen, Yusuf
    Centaurea L. sect. Plosimopappa, a local endemic group in the Mediterranean and South East Anatolia, is represented by only two species, namely C. ptosimopappa Hayek and C. ptosimopappoides Wagenitz in Turkey. Both these species show a very restricted distribution as serpentine habitat indicators and are recorded as vulnerable. Present study was carried out to enlighten the morphological, anatomical and ecological features of these two species in detail. The structure of achene, indumentum and pollen grains were investigated by using Scanning Electron Microscope (SEM). The capitulum, involucre and leaf structure of these two species are rather similar, but their achenes and pollen grains differ from each other. In C. ptosimopappa pollen spinules are densely distributed but in C. ptosimopappoides they are sparsely distributed. The achenes are obovate in C. ptosimopappa and rectangular in C. ptosimopappoides. C. ptosimopappa is a scrub species but C. ptosimopappoides is a subscrub species. A negative relation in terms of the proportion of sand to silt content of the soil and positive relation between the percentage of CaCo3 and pH was observed for C. ptosimopappa (p < 0.05). A negative relation in terms of the proportion of sand to silt content of the soil was observed in C. ptosimopappoides (p < 0.01).

    Plant species microendemism, rarity and conservation of pseudo - alpine zone of Kazdagi (Mt. Ida) national park - Turkey
    (Elsevier Science Bv, 2011) Ozturk, Munir; Uysal, Ismet; Karabacak, Ersin; Celik, Sezgin
    Kazdag (Mt. Ida) forms a natural border between the Provinces of Canakkale and Balikesir in the north-western part of Turkey. It was declared as National Park in 1993 because of its rich plant cover, a restricted zone of Abies nordmanniana ssp. equi-trojani forest, natural beauty and mythology. The pseudo-alpine zone consists of 189 specific and infraspecific taxa of vascular plants. A total of 55 endemic taxa (29.10%) were recorded from this area. Out of these 22 (40%) taxa are restricted only to this area, and 5 taxa are non-endemic but rare in Turkey. In this paper, habitat characteristics, conservation strategies and management of these taxa are given. Our investigations revealed that, out of 55 taxa, 12 are critically endangered (CR), 10 endangered (EN), 11 vulnerable (VU), 9 not threatened (NT) and 18 with lower risk (LC). Although Hieracium idae, Dianthus arpadianus var. trojanus, Minuartia garckeana and Paronychia sintenisii are recorded as data deficient (DD) category in IUCN criteria, these taxa are transferred to CR category.
