Turkey is on the main migratory route for many bird species although especially passerine migration is little known. The objective of this study is to document and analyze the diversity, abundances, daily and seasonal phenologies of migrating passerines at METU as well as compare seasonal phenologies with those obtained at Manyas Kuscenneti(Balikesir) and Cernek(Samsun) stations. The study covers autumn 2001, spring and autumn 2002 migration seasons. Methodology is based on the capture and ringing of passerines. In the first two seasons, intermittent sampling was the rule, but in autumn 2002 the study was continuous throughout the day and the season. Totally 1,832 individuals of 60 passerine species were ringed. Blackcap (Sylvia atricapilla) and Willow Warbler (Phylloscopus trochilus) were the two most common species. Blackcap dominates species composition in autumn seasons with a very high percentage (%33). Daily captures peaked in the early morning and with a smaller peak one hour before the sunset. Several waves of migrants were detected in autumn 2002, with most peaks in close correlation with those recorded at Cernek station, indicating some connection between migrant populations using both sites for stopover. Fat depositon rates showed at least Yalincak is a high quality stopover site for most migrant species since many species gained weight up to around 50% within a period of 10 days. This is the first study documenting passerine migration in Turkey, and it revealed that small wooded landscapes within less hospitable habitats provide crucial stopover habitat for many migrant passerines.

Autumn migration dynamicsi body mass, fatload and stopover behaviour of wşllow warbler (phylloscopus trochilus linnaeus 1758) at Manyas Kuşcenneti National Park (Northwestern Turkey) Keşapli Didrickson, Özgür; Bilgin, Cemal Can; Department of Biology (2007) Turkey lies on one of major migratory routes between Palearctic and Afrotropical regions.Despite its importance for many species, few studies exist on bird migration over Turkey. In this study, autumn migration dynamics and stopover behaviour of Willow Warbler (Phylloscopus trochilus), a small insectivorous passerine, was documented and analyzed at Manyas Kuşcenneti National Park (northwestern Turkey). Birds were mistnetted, ringed, measured, weighed and fat-scored from mid August in 2002 and end of August ...
Determining space use and demography of a reintroduced fallow deer (dama dama) population using GPS telemetry in Dilek Peninsula National Park, Turkey Durmuş, Mustafa; Bilgin, Cemal Can; Department of Biology (2019) The Fallow Deer (Dama dama) population in Turkey is presumed to be one of the few autochthonous populations globally. Although the species has been under protection since the 1960s, it had become restricted to a single site in Düzlerçamı, Antalya. Within the context of a reintroduction project, 21 deer were translocated into Dilek Peninsula National Park (Aydın, Turkey) in 2011 and 2012. Fifteen individuals were GPS-collared and monitored between 2011 and 2013 to understand their movements, habitat choice a...
An avifaunal survey of the Istranca mountains turkish thrace novel breeding bird records including the first breeding record of Wood Warbler Phylloscopus sibilatrix in Turkey Özkan, Korhan (2011-01-01) A breeding bird survey in the Istranca (Yıldız) mountains of Turkish Thrace seawards to the Black sea was conducted May–August 2009. Eighty-eight days of field work in 697 locations generated novel breeding evidence for several species. The survey provided the first certain evidence of Wood Warbler Phylloscopus sibilatrix breeding in Turkey. Strong evidence for breeding of Yellowhammer Emberiza citrinella, with a relatively widespread distribution, was also gathered. The survey suggested that Green Sandpipe...
Comparative sequence analysis of the internal transcribed spacer 2 region of Turkish red pine (pinus brutia ten.) and natural aleppo pine (pinus halepensis mill.) populations from Turkey Tozkar, C. Özge; Kaya, Zeki; Department of Biology (2007) Turkish red pine (Pinus brutia) is wide-spread and an important forest tree species in Turkey, occurring mainly in southern, western and north-western Turkey and as small isolated populations in the Black Sea region. Aleppo pine (Pinus halepensis) has naturally found only in Adana and Muğla provinces as small population in mixture with Turkish red pine. Although Turkish red pine and Aleppo pine are morphologically different, Turkish red pine has been regarded as subspecies of Aleppo pine by some taxonomists...
Monitoring of nuclear abnormalities in peripheral erythrocytes of three fish species from the Goksu Delta (Turkey): genotoxic damage in relation to water pollution Ergene, Serap; Cavas, Tolga; Celik, Ayla; Koleli, Nurcan; Kaya, Filiz; Karahan, Arzu (2007-05-01) Goksu Delta is a specially protected area in the Mediterranean region of Turkey. The delta is classified as a Wetland of International Importance according to the RAMSAR Convention on Wetlands of International Importance. Increases in population have recently taken place in this region due to heavy agricultural activities and discharges of anthropogenic wastes. In the present study, frequencies of erythrocytic nuclear abnormalities such as, micronuclei (MN) and nuclear buds (NB) were investigated in periphe...
