    Astragalus bartinense (Fabaceae), a new species from Turkey
    (Univ Zagreb, Fac Science, Div Biology, 2020) Tunckol, Bilge; Ayta, Zeki; Aksoy, Necmi; Fisne, Ahter
    Astragalus bartinense is described as a new species from Bartin Province in Northern Anatolia, Turkey. The new species is close to A. depressus L. and A. froedinii Murb., but distinctly differs from A. froedinii in having hairy fruit, long stipules (10-12 mm) and peduncle (10-25 mm). It also differs from A. depressus in having long stipules and a stipitate and glabrous ovary. Taxonomic descriptions, micromorphology of pollen and seed and geographical distribution are presented.

    Diversity and ecology of forest communities in Kure Mountains National Park of Turkey
    (Univ Austral Chile, Fac Ciencias Forestales, 2020) Tunckol, Bilge; Aksoy, Necmi; Coban, Suleyman; Zengin, Hayati
    This study aimed at analyzing the diversity and ecological characteristics of forest associations (121 releves classified under eight associations) in Ktire Mountains National Park. Ordination analyses (DCA and CCA) and response curves were used to reveal ecological characteristics of vegetation using soil parameters (pH, electrical conductivity, sand, clay and dust content, soil moisture) and topographical variables (altitude, slope, potential direct incident radiation and heat load). Ecological conditions of communities were also tested using average Ellenberg indicator values (EIVs). Among forest associations, the highest species diversity was found in Phillyreo latifoliae-Pinetum brutiae and the lowest diversity in Hedero-Castanetum sativae, which had a dense Rhododendron ponticum shrub layer. However, Salicio-Platanet um orientale and Buxo sempervirens-Ccupinetum betuli had the highest beta diversity since they harbored unique species composition. Conditional effects of altitude, slope, pH and electrical conductivity, soil dust and sand content, sandy-loam and loam soil types presented significant contributions in species composition. While Carpino-Querretum petraeae was found on soil with high dust content having high pH and electrical conductivity values, Quercetum roburi-Aceretum campestri and Salicio-Platanettun orientale were related to soil with loam. Species responses to soil and topographical variables varied for most tree species. Light EIVs, which has a high positive correlation with potential direct incident radiation and heat load, related to Phillyreo latifoliae-Pinetum brutiae and Salicio-Platanetum orientale. Riverside forest communities diffixed from other communities in nutrient and humidity EIVs. However, EIVs did not show a good correlation with associated soil parameters such as soil moisture-humidity EIVs and soil pH-acidity EIVs.

    Polystichum asiae-minoris (Dryopteridaceae), a new fern from Kastamonu, Turkey
    (Magnolia Press, 2020) Tunckol, Bilge; Yasayacak, Hasan; Liang, Zhen-Long; Aksoy, Necmi; Zhang, Li-Bing
    A new fern of Polystichum (Dryopteridaceae), P. asia-minoris, is described and illustrated from Horma Canyon in the borders of Kure Mountains National Park in Kastamonu Province located in the north of Turkey. Polystichum asia-minoris is distinguishable from the morphologically similar P. obliquum by having pinnae abaxially densely covered with broad-type microscales. It is not certain to which lineage the new species closely allied. The new species has extremely narrow distribution and is classified as Critically Endangered (CR) following IUCN Red List Criteria.
