    HABITAT USE BY TIT SPECIES IN THE YUVACIK WATERSHED, TURKEY
    (Parlar Scientific Publications (P S P), 2018) Beşkardeş, Vedat; Keten, Akif; Arslangündoğdu, Zeynel; Anderson, James T.
    Tits are small insectivorous passerines inhabiting much of Turkey; spatially distributed due to habitat selection. The objective of the current study was to document habitat preference of the tit community in the Yuvacik Watershed in northwestern Anatolian. We tested the hypothesis that tits abundance changed based on habitat types. We sampled a total of 12 plots from 4 habitat types (deciduous forest, coniferous forest, scrub-shrub, and farmland) monthly during 2007. We recorded four (4) tit species: Blue tit Cyanistes caeruleus, Coal tit Periparus ater, Great tit Parus major, and Marsh tit Poecile palustris; 354 individual birds were counted during 12 surveys. Tits were influenced by habitat types in Yuvacik watershed. Coal tit are adapted to coniferous forests. Great tit and Blue tit were distributed widely in coniferous forests, scrub-shrub areas, and farmlands. Marsh tit was associated primarily with deciduous woodland. Elevation, cover percentage, and vegetation height influenced positively the abundance of total and individual species. Three parameters (elevation (m), canopy cover (%), and maximum habitat height (m)) showed differences among habitat types for tit species. Coniferous forests and deciduous forests exhibited similar characteristic, as did scrub-shrub areas and farmlands. Tit species are resident and reproduce in the Yuvacik watershed. Hedgerows in farmland, and mature habitats should be protected and sustained to enhance breeding success of tits.

    Karacaların (Capreolus capreolus L, 1758) Türkiye'nin yaban hayatı açısından önemi
    (2008) Beşkardeş, Vedat; Keten, Akif; Arslangündoğdu, Zeynel
    Karacalar (Capreolus capreolus L, 1758) (Cervidae, ARTIODACTYLA) Türkiye'deki Cervidae familyasının (Geyikgiller) en küçük türüdür. Karacaların, diğer Cervidae türlerine göre ekolojik ve biyolojik üstünlükleri, onları Türkiye'nin yaban hayatı ve avcılığı açısından önemli hale getirmektedir. Geçmiş yıllarda yapılan kaçak ve bilinçsiz avcılık sonucu, nesli neredeyse yok olma aşamasına gelmiş olan karacalar yalnızca koruma sahalarında varlıklarını sürdürebilmişlerdir. Günümüzde avlanmanın kısmen daha düzenli hale getirilmesi, kaçak avcılara uygulanan cezaların caydırıcılığı ve insanların doğa konusunda bilinçlenmeye başlaması diğer yaban hayvanları gibi karacaların da sayılarının artmasına neden olmuştur. Bu çalışmada öncelikle karacaların biyolojileri, yayılış alanları, populasyon durumları ve habitatları üzerinde durulmuş ve bu bilgiler ışığında karacaların ülkemiz av ve yaban hayatı açısından önemi ortaya konmaya çalışılmıştır.

    Observation on ornithofauna of Kocaeli-Yuvacik dam watershed in Turkey
    (Triveni Enterprises, 2010) Keten, Akif; Beşkardeş, Vedat; Arslangündoğdu, Zeynel
    The objective of this study was to determine the birdspecies in the Yuvacik Dam watershed in the province of Kocaeli, The total area of the study site was 25800 ha, and was subdivided to 60 plots (the size of each plot, 2x2 km). Observations and inventory for each species were carried out. A total of 130 species belonging to 38 genus of 16 orders were identified. Eighty-seven were classified as Passeriformes. Forty two species breed in the region. A total of 21223 birds were counted. According to IUCN criteria, two species, (Ficedula semitorquata (Von H., 1885) and Sitta krueperi (Pelzeln, 1863), were categorized as near threatened (NT).

    Ornithofauna of Efteni Lake In Düzce
    (Düzce Üniversitesi, 2012) Keten, Akif; Arslangündoğdu, Zeynel; Selmi, Erdal
    Wetlands, many bird species sheltering, feeding and breeding are one of the important habitats. Anyinterference with wetlands directly affects the living things around here. In the past, which has 580 ha area EfteniLake, in the 1970s reduced up to 25 ha and the present work later in the year 1992 has reached 170 ha area. Thisstudy of bird species living in Lake Efteni determination is the first study. Total of 129 species were identified inthe study area. Maximum number of species have been identified in August. A total of 38 species produced inthe area where the IUCN criteria Aythya nyroca (Güldenstaedt, 1770) and Coracias garrulus L., 1758 nearthreated (NT), Aquila clanga Pall., 1811 vulnerable (VU), Oxyura leucocephala (Scop., 1769), endangered ( EN)was identified as a protected status.
