Population structure and genetic analysis of narrow-clawed crayfish (Astacus leptodactylus) populations in Turkey
(Springer, 2014)The genetic differentiation among Turkish populations of the narrow-clawed crayfish was investigated using a partial sequence of cytochrome oxidase subunit I gene (585 bp) of 183 specimens from 17 different crayfish ... -
Potential distribution modeling and morphology of pelias barani (Bohme and Joger, 1983) in Turkey
(Science Press, 2015)The climatic preferences of Pelias barani, a rare Pontic endemic viper, are analysed and a new locality record is reported. According to species distribution modeling, with the average test AUC was was 0.904 +/- 0.068, ... -
Potential distribution under different climatic scenarios of climate change of the vulnerable Caucasian salamander (Mertensiella caucasica): A case study of the Caucasus Hotspot
(Springer, 2018)Amphibians are strongly affected by climate change like many vertebrate animals. To address this problematic situation, we examined the potential effect of climate change on the distribution of Mertensiella caucasica (Waga, ... -
Potential habitats of an alien species (Asterias rubens Linnaeus, 1758) in the Black Sea: its current and future distribution patterns
(Springer Heidelberg, 2022)The Atlantic common starfish, Asterias rubens, has arrived firstly at the Marmara Sea in 1996 and to the Black Sea in 2007. In this study, we have exhibited the possible potential distribution of Asterias rubens throughout ... -
Potential therapeutic effect of turmeric contents against SARS-CoV-2 compared with experimental COVID-19 therapies: in silico study
(Taylor & Francis Inc, 2020)Inspired by the 'There is no scientific evidence that turmeric prevents COVID-19' statement made by WHO, the protective or therapeutic potential of the compounds in turmeric contents was investigated against COVID-19 with ... -
Precision and accuracy of ST-EDXRF performance for As determination comparing with ICP-MS and evaluation of As deviation in the soil media
(Pergamon-Elsevier Science Ltd, 2014)The present study was conducted to (i) determine the precision and accuracy of arsenic measurement in soil samples using ST-EDXRF by comparison with the results of ICP-MS analyses and (ii) identify the relationship of As ... -
Predicted distribution patterns of Pelias kaznakovi (Nikolsky, 1909) in the caucasus hotspot with a new locality record from Turkey
(Folium Publ Co, 2016)We represent climatic preferences of Pelias kaznakovi, which is a Caucasus endemic viper species together with a new locality record. Male P. kaznakovi specimen has morphological similarities in terms of pholidosis characters ... -
Predicting the success of an invader: Niche shift versus niche conservatism
(Wiley, 2019)Invasive species can encounter environments different from their source populations, which may trigger rapid adaptive changes after introduction (niche shift hypothesis). To test this hypothesis, we investigated whether ... -
Preliminary data on the age structure of Asaccus barani (Baran's leaf-toed gecko) from southeastern Anatolia, Turkey
(2015)In this study, the age structure of an Asaccus barani sample from Şanlıurfa (southeastern Anatolia, Turkey) was determined by skeletochronology for the first time. A total of 17 preserved adults (7♂♂, ... -
Preparation and antimicrobial activity evaluation of some new bi- and triheterocyclic azoles
(Springer Birkhauser, 2013)Synthesis of the carbothioamides (5, 13, 22) was performed starting from 3H-1,2,4-triazol-3-ones (2, 17) by several steps, and then, these carbothioamides was converted to triheterocyclic compounds incorporating 1,2,4-triazole, ... -
