Kalaycı, Tuğba Ergül; Gül, Serkan; Dursun, Cantekin; Karaoğlu, Handan; Özdemir, Nurhayat (Pleiades Publishing Inc, 2019)We describe here for the first time the body size and age of the Common Toad (Bufo bufo) from high (Trabzon, 1090 m and Kastamonu, 925 m above sea level) and low (Yalova, 65 m above sea level) altitudes in Turkey using ... -
Age structure, body size, and sexual dimorphism in a high-altitude population of pelophylax ridibundus (Pallas, 1771)
Gül, Serkan; Dursun, Cantekin; Tabak, Ceren; Büyüksofuoğlu, Sümeyye; Özdemir, Nurhayat (MDPI, 2024)This study aimed to describe the morphological characteristics and age structure of a P. ridibundus population sampled from a high altitude. For this purpose, a total of 54 adult frogs (33 males and 21 females) were collected ... -
Comparison of the ecological niche of two closely related toads (Bufo bufo and Bufo verrucosissimus)
Gül, Serkan; Dursun, Cantekin; Kutrup, Bilal; Üzüm, Nazan; Özdemir, Nurhayat (Brill, 2023)Understanding climatic variables to determine the ecological niche is crucial to explaining species distributions and revealing how sister species coexist within a geographic area. Here, we used ecological niche modeling ... -
Easternmost distribution of Bufo bufo (Linnaeus, 1758) in Türkiye: implications for the putative contact zone between B. bufo and B. verrucosissimus
Dursun, Cantekin; Özdemir, Nurhayat; Gül, Serkan (Springer, 2022)The geographic range of a species is crucial for obtaining information on the exact distribution of the species. The geographic data are important for delimiting distinct species or exploring the degree of diferentiation ... -
Genetic data to describe the hybrid zone between Bufo bufo (Linnaeus, 1758) and Bufo verrucosissimus (Pallas, 1814) in northeastern Türkiye
Dursun, Cantekin; Sánchez-Monte, Gregorio; Özdemir, Nurhayat; Gül, Serkan; Martínez-Solan, Iñigo (Brill Academic Publishers, 2023)Hybrid zones are geographic areas where individuals from distinct taxa meet, mate, and hybridize. These zones may have complex histories, but many of them originated relatively recently, during climatic oscillations in the ... -
Interspecific and intraspecific size and shape variation in skull of two closely related species Bufo bufo (Linnaeus, 1758) and Bufo verrucosissimus (Pallas, 1814) from Turkey
Üzüm, Nazan; Özdemir, Nurhayat; Dursun, Cantekin; Kutrup, Bilal; Gül, Serkan (TUBİTAK Scientific & Technical Research Council Turkey, 2021)Anurans are the most suitable vertebrate group to see the development and also evolution in the skull, compared to other terrestrial vertebrates as they show highly derived morphology. For this reason, the cranium of anurans ... -
Morphological variability and age structure in a population of Bufo verrucosissimus (Anura: Bufonidae) from Artvin, Turkey
Dursun, Cantekin; Özdemir, Nurhayat (University Sao Esalo, 2022)Morphological variability and age structure in a population of Bufo verrucosissimus (Anura: Bufonidae) from Artvin, Turkey. We investigated morphological diversity (external body traits, coloration patterns and skin ... -
The presence of microplastics in Baran’s newt (Neurergus barani Öz, 1994) and the spotted newt (Neurergus strauchii Steindachner, 1887)
Dursun, Cantekin; Karaoğlu, Kaan; Avcı, Aziz; Gül, Serkan (Springer, 2024)Microplastics (MPs), tiny plastic particles less than 5 mm in size, have emerged as a common and worrying pollutant in marine, freshwater, and terrestrial environments worldwide. In this study, we revealed the microplastic ... -
Road mortality report of the genus bufo in northeastern Türkiye
Dursun, Cantekin; Özdemir, Nurhayat; Gül, Serkan (Springer, 2023)Abstract: Amphibians, especially those living near lakes, wetlands, and small water bodies, are the most vulnerable vertebrate group to vehicle collision. The aim of this study was to monitor and determine the causes of ... -
Sexual shape dimorphism in Bufo verrucosissimus (Pallas, 1814) from Lake Borçka Karagöl, Türkiye
Dursun, Cantekin; Özdemir, Nurhayat; Gül, Serkan (Hungarian Natural History Museum, 2023)Sexual dimorphism, i.e., differences in morphology between sexes of a species caused by intersexual differences in the strength or direction of sexual or natural selection, is preva-lent throughout the animal kingdom. ... -
Sexual size and shape dimorphism in Turkish common toads (Bufo bufo Linnaeus 1758)
Dursun, Cantekin; Gül, Serkan; Özdemir, Nurhayat (Wiley, 2021)Differences in male and female traits (sexual dimorphism [SD]) are widespread in animals. Dimorphism in morphological characters evolves under the effect of environmental and genetic factors and is shaped by natural and ... -
Spatiotemporal distribution of microplastics in true frogs (Ranidae: Pelophylax) populations from Turkiye
Dursun, Cantekin; Karaoğlu, Kaan; Özdemir, Nurhayat; Candan, Kamil; Kumlutaş, Yusuf; Ilgaz, Çetin; Gül, Serkan (Elsevier, 2023)Microplastics (MPs), which are of increasing concern in almost all ecosystems, continue to be an environmental threat. In the present study, the presence of MPs is investigated by using the gastrointestinal tracts (GITs) ... -
