Öğe Additional notes on the spider fauna of Turkey (Araneae)(Tubitak Scientific & Technical Research Council Turkey, 2012) Kunt, Kadir Bugac; Kaya, Rahsen Saltanat; Ozkutuk, Recep Sulhi; Danisman, Tarik; Yagmur, Ersen Aydin; Elverici, MertThis paper presents the results of recent field surveys and provides new data on the spider fauna of Turkey. The following 9 taxa are new records for Turkey: Larinia chloris (Audouin, 1826); Macrothele sp.; Arctosa tbilisiensis Mcheidze, 1946; Pisaura consocia (O. P.-Cambridge, 1872); Prodidomus redikorzevi Spassky, 1940; Macaroeris flavicomis (Simon, 1884); Scytodes velutina Heineken & Lowe, 1832; Achaeridion conigerum (Simon, 1914); and Phoroncidia paradoxa (Lucas, 1846). New locality data are provided for the following previously but rarely recorded species: Spermophora senoculata (Duges, 1836); Ariadna insidiatrix Audouin, 1826; and Segestria senoculata (Linnaeus, 1758). Taxonomic, zoogeographical, and ecological data are given for each species.Öğe Characterization of Leiurus abdullahbayrami (Scorpiones: Buthidae) venom: peptide profile, cytotoxicity and antimicrobial activity(Biomed Central Ltd, 2014) Erdes, Efe; Dogan, Tugba Somay; Cosar, Ilhan; Danisman, Tarik; Kunt, Kadir Bogac; Seker, Tamay; Ozen, CanBackground: Scorpion venoms are rich bioactive peptide libraries that offer promising molecules that may lead to the discovery and development of new drugs. Leiurus abdullahbayrami produces one of the most potent venoms among Turkish scorpions that provokes severe symptoms in envenomated victims. Methods: In the present study, the peptide profile of the venom was investigated by electrophoretic methods, size-exclusion and reversed-phase chromatography and mass spectroscopy. Cytotoxic and antimicrobial effects were evaluated on a breast cancer cell line (MCF-7) and various bacterial and fungal species. Results: Proteins make up approximately half of the dry weight of L. abdullahbayrami crude venom. Microfluidic capillary electrophoresis indicated the presence of 6 to 7 kDa peptides and proved to be a highly practical peptidomics tool with better resolution when compared to conventional polyacrylamide gel electrophoresis. Mass spectroscopy analysis helped us to identify 45 unique peptide masses between 1 to 7 kDa with a bimodal mass distribution peaking between molecular weights of 1 to 2 kDa (29%) and 3 to 4 kDa (31%). L. abdullahbayrami crude venom had a proliferative effect on MCF-7 cells, which may be explained by the high concentration of polyamines as well as potassium and calcium ions in the arachnid venoms. Antimicrobial effect was stronger on gram-negative bacteria. Conclusions: This work represents the first peptidomic characterization of L. abdullahbayrami venom. Considering the molecular weight-function relationship of previously identified venom peptides, future bioactivity studies may lead to the discovery of novel potassium and chloride ion channel inhibitors as well as new antimicrobial peptides from L. abdullahbayrami venom.Öğe DESCRIPTION OF A NEW ZODARIINE SPIDER, ZODARION GAZIANTEPENSE SP.

Z. gaziantepense sp. n. can be easily distinguished from all other Turkish and European representatives of the genus by the structure of a triangular-shaped median apophysis.Öğe DESCRIPTION OF THE HITHERTO UNKNOWN FEMALE OF PELECOPSIS TOPCUI (TURKES ET. AL. 2015), COMBN (ARANEAE, LINYPHIIDAE)(Amer Entomol Soc, 2020) Danisman, Tarik; Cosar, Ilhan; Ozkutuk, Recep Sulhi; Kunt, Kadir BogacIn this study, Abacoproeces topcui Turkes et. al. 2015 is shown to be an inappropriate generic assignment. The male and hitherto unknown female are redescribed and the species is transferred to Pelecopsis comb.n.Öğe First description of the females of two species of Zodarion (Araneae: Zodariidae)(Magnolia Press, 2022) Cosar, Ilhan; Danisman, Tarik; Elverici, MertThe females of Zodarion samos Bosmans, 2009 and Zodarion varoli Akp??nar, 2016 are described for the first time. Z. samos Bosmans, 2009 is further a new record to the Turkish araneofauna. Characteristic features and photographs of both species are presented, and known localities in Turkey are provided. Previous records of Zodarion rubidum Simon, 1914, and Zodarion ruffoi Caporiacco, 1951 from Turkey are based on misidentifications and shall be omitted from the national species list.Öğe A new species of Coelotes Blackwall, 1841 (Araneae: Agelenidae) from Turkey(Tubitak Scientific & Technical Research Council Turkey, 2016) Danisman, Tarik; Karanfil, Kubra Ceren; Cosar, IlhanThe species Coelotes sinopensis sp.n. is described from Sinop Province, Turkey. Differences between the new species and related species are discussed.Öğe A New Species Of Tegenaria Latreille, 1804 (Aranea: Agelenidae) From Turkey(Amer Entomol Soc, 2015) Danisman, Tarik; Karanfil, Kubra CerenA new species, Tegenaria vanensis sp. n. is described based on males from Van Pro vince in Turkey.
