Özet
Comparing to the ostracod studies on the other islands in the world, studies on the ostracod fauna of the islands in Antarctica are scarce. During the sixth Turkish Antarctica Expedition (TAE 6) to the islands (Dismal, Horseshoe, Nansen, Livingstone) in Western Antarctica, sediment and water samples were collected from 32 different water bodies (lakes, ponds, creeks, springs, littoral zones of sea). Among several new reports of different taxonomic groups which are under investigation, a new marine ostracod species (Xestoleberis nansenensis n. sp.) was encountered from Nansen Island. This is the first report of an ostracod from this island below 60 & DEG; S in Antarctica. The new species has several different features both in the carapace and soft body parts. Absence of ostracods from other islands sampled may be related to several a/biotic factors, such as water chemistry (e.g., relatively low calcium levels), extreme aquatic conditions (e.g., low-temperature values), improper habitat conditions (e.g., too little or absence of sediment in the water bodies), and isolation of the island(s) from the mainland. Although our new species is a marine form, comparative literature review indicated that there is no non-marine living ostracod species reported from the islands visited during the expedition. Possible reasons are discussed.
Açıklama
I thank to Dr. Takahiro Kamiya (Kanazawa University) for comments on the species and sending me published materials. I thank Dr. Randy Gibson (San Marcos Aquatic Resources Center, U.S. Fish and Wildlife Service) for his help on the English. Also, Yohanna Klanten (Universite Laval, Quebec) is thanked for her assistance during core samplings of the lakes. Dr. Alaettin Tuncer, Alper Ataman, and Mirac Aksu are thanked for their help on digitizing line drawings and providing laboratory assistance and SEM photographing. This study was carried under the auspices of the Presidency of the Republic of Tuerkiye, supported by the Ministry of Industry and Technology, and coordinated by TUEBITAK MAM Polar Research Institute. This work was supported by TUEBITAK (Project No: 121Y372).
