    Genetic Status of Hemidactylus turcicus (Linnaeus, 1758) from canakkale (Turkiye)
    (Pleiades Publishing Inc, 2023) Kalayci, T. Erguel; Kurtul, D.; Gul, C.; Tosunoglu, M.
    Hemidactylus turcicus is a member of one of the most species-rich reptile genera and is known as an invasive species closely associated with humanized environments. Its phylogeography is often interpreted to be the result of recurrent human-mediated introductions. canakkale is the place that acts as a species corridor for the Anatolia peninsula. Farther, this place is connected with an adjacent island. Here, we tender the genetic structure of H. turcicus from both islands (Bozcaada) and the mainland of canakkale using mtDNA (Cyt b and COI gene regions). We used molecular tools to assess species identity and compare our sequences to a database containing various expertly identified species. We also applied DNA barcoding to report and release our data to the public. DNA barcoding is a reliable way to identify and store data on invasive species. Not surprisingly, specimens from canakkale genetically resemble other Mediterranean conspecifics from Italy, Greece, and Albania. Albeit, we found quite genetic differences between samples from canakkale and Adana. Not all cryptic lineages have been investigated taxonomically in H. turcicus. Researchers should implement genetic monitoring of specimens from its all-distributed area.

    Testicular Morphologies of Two Sympatric Podarcis Species
    (Pleiades Publishing Inc, 2024) Baycan, B.; Kurtul, D.; Boran, B.; Ozgul, C. N.; Gul, C.; Tosunoglu, M.
    The reproductive strategies of reptiles vary according to many factors. In lizards, intraspecific and interspecific competition, and environmental and seasonal factors affect their reproductive biology. This study aimed to conduct a comparative analysis of testis sizes in the sympatrically coexisting species, Podarcis muralis and Podarcis tauricus, located in Kof & ccedil;az, K & imath;rklareli, Turkey, considering both intra-species and inter-species variations. Changes in body sizes and testis sizes according to months were monitored. As a result, it was determined that in both species, there was a positive correlation between body size and testis size, and that in P. tauricus, both body and testis sizes were higher compared to P. muralis, showing a significant difference. It was also observed that in the P. muralis species, the testis size reached its peak value in April (mean daily temperature 9.9 degrees C), while in the P. tauricus species, it reached the highest value in May (mean daily temperature 15.5 degrees C). It was found that the testis size in P. muralis reached its lowest value in August (mean daily temperature 23.8 degrees C), while in P. tauricus, it was lowest in September (mean daily temperature 20.2 degrees C). The fact that testis size is high in different months in these two sympatric species suggests that their active breeding periods differ.
