Mollusk fauna and regional distribution of the Kelkit Basin, Türkiye

Öz

This study was conducted between October 2023 and October 2024 at a total of 85 stations covering the provinces of Gümüşhane, Giresun, Erzincan, Ordu, Tokat, and Sivas, with the aim of determining the freshwater mollusk fauna of the Kelkit Basin. The taxonomic identifications and habitat characteristics of the species recorded during the research were determined. From the study area, seven families belonging to the class Gastropoda were identified, including the species Oxyloma elegans, Peregriana labiata, Gyraulus piscinarum, Physella acuta, Potamopyrgus antipodarum, Valvata macrostoma, and Theodoxus fluviatilis. From the class Bivalvia, Dreissena polymorpha gallandi and Dreissena caputlacus were identified. In the Kelkit Basin, the alien invasive mollusks D. caputlacus, D. p. gallandi, P. acuta, and P. antipodarum were recorded from Kılıçkaya Reservoir, Çamlıgöze Reservoir, and Tepekışa Reservoir, but not from Sadak Reservoir and Gölova Reservoir. P. antipodarum, which has previously been reported to spread across many regions of Türkiye, was recorded from this basin for the first time. The potential impacts of this occurrence on the Kelkit Basin were also discussed.

Kelkit havzasının mollusk faunası ve bölgesel bağılımı, Türkiye

Bu çalışma; Kelkit Havzası’nın tatlı su mollusk faunasını belirlemek amacıyla Ekim 2023- Ekim 2024 tarihleri arasında Gümüşhane, Giresun, Erzincan, Ordu, Tokat ve Sivas illerini kapsayan toplam 85 istasyonda gerçekleştirilmiştir. Araştırma kapsamında tespit edilen türlerin taksonomik tanımlamaları ve habitat özellikleri belirlenmiştir. Araştırma bölgesinden Gastropoda sınıfından 7 familya ve bu familyalara ait olan Oxyloma elegans, Peregriana labiata, Gyraulus piscinarum, Physella acuta, Potamopyrgus antipodarum, Valvata macrostoma ve Theodoxus fluviatilis türleri tespit edilmiştir. Bivalvia sınıfından ise Dreissena polymorpha gallandi ve Dreissena caputlacus türleri belirlenmiştir. Kelkit havzasında yabancı istilacı mollusklar olan D. caputlacus, D. p. gallandi, P. acuta ve P. antipodarum Sadak baraj gölü ve Gölova baraj gölü hariç Kılıçkaya Baraj Gölü, Çamlıgöze Baraj Gölü ve Tepekışa baraj göllerinden tespit edilmiştir. Daha önce Türkiye’nin birçok bölgesine yayıldığı bildirilen P. antipodarum türü ise bu havzadan ilk defa bildirilmiştir. Bu durumun Kelkit Havzasına olası etkileri de tartışılmıştır.
