    Population size of the marsh frog (Rana ridibunda Pallas, 1771) in Lake Yayla (Denizli, Turkey)
    (2007) Ayaz D.; Tok C.V.; Mermer A.; Tosunoǧlu M.; Afsar M.; ÇiÇek K.
    The population size of marsh frogs (Rana ridibunda) was estimated using the mark-recapture method in Lake Yayla (Buldan, Denizli, Turkey). According to the results, the mean estimated population was 14,733 and the sex ratio was female biased (male: female, 0.56). The main limiting factors of the marsh frog population are also outlined. © Tübitak.

    Population estimate and body size of European pond turtles (Emys orbicularis) from Pazaraǧaç (Afyonkarahisar/Turkey)
    (Versita, 2007) Ayaz D.; Fritz U.; Tok C.V.; Mermer A.; Tosunoğlu M.; Afsar M.; Çiçek K.
    Data on population size, adult sex ratio, body size and mass are provided for a population of the turtle Emys orbicularis near Pazaraǧaç (Afyonkarahisar/Turkey). Using the mark-recapture method (triple catch), a population size of 664 turtles was estimated (95% confidence interval, range 332-996), corresponding to a density of 83 turtles per hectare (range 41.5-124.5). The adult sex-ratio was significantly skewed in favor of males (2.02 males: 1 female; P < 0.001). Almost all recorded specimens were adult (98.1%). Mean straight carapace length (SCL) and body mass (BM) of adult turtles were: SCL = 128.65 mm, BM = 345 g for males (n = 168) and SCL = 135.37 mm, BM = 463 g for females (n = 83). © 2007 Institute of Zoology, Slovak Academy of Sciences.

    Aspect of population structure of the European pond turtle (Emys orbicularis) in Lake Yayla, Western Anatolia, Turkey
    (2008) Ayaz D.; Fritz U.; Atatür M.K.; Mermer A.; Çiçek K.; Afsar M.
    Our main objective was to establish the population size, density, body size, and sex ratio of a local Emys orbicularis population. We examined the population structure of E. orbicularis in Lake Yayla, Buldan (Denizli), Turkey, using capture-recapture methods. The population consisted of 54% males, 42% females, and 4% juveniles. The adult sex ratio was significantly skewed in favor of males. Using the Jolly program, the population size was estimated at 1,462 (95% CI = 1,161-1,763), corresponding to a density of 81 turtles per hectare of optimal habitat. Females were larger than males. In carapace length, the Lake Yayla population resembles other small-sized populations inhabiting the southern parts of the species' range. The conservation status of the Turkish populations and their main threats are also discussed. Copyright 2008 Society for the Study of Amphibians and Reptiles.

    Fauna, Seasonal Activity, and Altitudinal Distribution of Phlebotomine Sand Flies (Diptera: Psychodidae) in Leishmaniasis Endemic Area, Aydın Mountains, and Surroundings in Western Turkey; [Türkiye’nin Batısında, Leishmaniasis’in Endemik Olduğu Aydın Dağları ve Çevresinde Kum Sineği (Diptera: Psychodidae) Faunası, Mevsimsel Aktiviteleri ve Yüksekliğe Göre Dağılımları]
    (Galenos Publishing House, 2022) Arserim S.K.; Mermer A.; Özbel Y.
    Objective: Human and canine leishmaniasis (CanL) are endemic in Turkey, and cutaneous leishmaniasis (CL) is a primary public health problem among vector-borne diseases, with 1500-2000 autochthonous cases per year. In this study, we aimed to perform a comprehensive entomological survey, including the detection of sand fly fauna, seasonal activity, and altitudinal distribution, together with the ecological features of Aydın Mountains and their surroundings that are endemic areas for CL caused by Leishmania tropica and CanL caused by L. infantum MON-1. Methods: The survey was carried out from June 2009 to July 2010. Ten localities with different altitudes were selected. Sand fly collection was done every 15 days in July and August when sand flies are most active and every 30 days between September and June (14 months, 16 samplings) using CDC light traps and sticky traps. During the collection, the temperature, humidity, and ecological and environmental features were recorded. Sand fly specimens were dissected and identified at species level using written keys. Results: A total of 6712 sand fly specimens (3268 females and 3444 males) were collected from 10 localities throughout all study periods. Species identification revealed that nine and three species belonging to Phlebotomus (P. major s.l. 30.38%, P. tobbi 22.93%, P. papatasi 5.88%, P. sergenti s.l. 4.51%, P. alexandri 4.26%, P. simici 3.50%, P. burneyi 0.63%, P. brevis 0.45%, and Transphlebotomus spp. 0.28%) and Sergentomyia (S. dentata 23.17%, S. minuta 2.43%, and S. antennata 1.58%) were found, respectively. The seasonal activities of these 12 sand fly species were determined, and P. major s.l. and P. tobbi, which were probable vectors of VL and CanL, were present in the study area. P. sergenti s.l., a probable vector of CL, was also found in the region and was active for seven months between April and October. P. sergenti s.l. was found in the 400–600 m altitude in July, while P. major and P. tobbi were found in high densities in the 200-400 m altitude in September. Conclusion: Our results showed that leishmaniasis vectors are present in different altitudes in the Aydın mountains and surroundings. The findings revealed the time intervals of parasite transmission in the area and the period of applying protective measures, such as insecticide application. © 2022, Galenos Publishing House.
