Öğe Biodiversity richness created by the Tigris River in the Hevsel Gardens and its surroundings in southeastern Turkey(Universitatea din Oradea, 2022) Ünlü E.; Ertekin A.S.; Biricik M.; Tusun S.; Şeşen R.; Yakali N.; Coşkun Y.The historical Hevsel Gardens in Diyarbakır, Turkey, was registered as a UNESCO cultural heritage site in 2015. The biodiversity of the habitats was revealed by compiling the inventory obtained from the field studies in the Hevsel Gardens, and its surroundings, including the Tigris River between 2002-2021, and from the literature containing studies conducted in the region. The results indicate that there are 607 species of flora including phytoplankton-phytobenthos and plants and 635 species of animals consisting of invertebrates (352 species), fish (27 species), amphibians (3 species), reptiles (15 species), birds (215 species) and mammals (23 species). The records revealed the following species under different threatened categories of IUCN at a global scale and The Red Book of Turkish Plants for endemic Plants: Vicia esdraelonensis (VU) and Trifolium aintabense (NT) from plants; Leguminaia wheatleyi (NT), Unio mancus (NT) from Mollusca; Oedipoda aurea (NT) from Insecta; Arabibarbus grypus (VU), Carasobarbus kosswigi (VU), Luciobarbus esocinus (VU) from Fish; Testudo graeca (VU) and Rafetus euphraticus (EN) from reptiles; Oxyura leucocephala (EN), Falco cherrug (EN), Aythya ferina (VU), Streptopelia turtur (VU), Otis tarda (VU), Falco vespertinus (VU), Pelecanus crispus (NT), Aythya nyroca (NT), Vanellus vanellus (NT), Limosa limosa (NT), and Numenius arquata (NT) from birds; Vormela peregusna (VU) and Lutra lutra (NT) from mammals. The factors threatening the area have been revealed and discussed in the paper. For the sustainable conservation of rich biodiversity, it is recommended that this region of the Tigris River and Hevsel Gardens should be protected within the scope of “Qualified Nature Protection Areas”. © Biharean Biologist, Oradea, Romania, 2022.Öğe Copper and zinc contamination of the Tigris River (Turkey) and its wetlands(2001) Gümgüm B.; Ünlü E.; Akba O.; Yildiz A.; Namli O.Copper and zinc were determined in the water and freshwater fish (Carasobarbus luteus) from the Tigris River, and its surrounding soils, wheat and mushrooms by using a Jobin Yvon model 24 Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES). The average contents of Cu and Zn in the river water, were found 0.03 mg L-1 and 0.14 mg L-1, and in the liver of fish were found approximately 454 mg kg-1 and 290 mg kg-1 respectively. All Cu and Zn values in the soils that irrigated with the river water, were found higher than the non irrigated soils in the same area. The similar results were observed in wheat and mushrooms, that near or far from the river.Öğe Notes on the catfish, silurus triostegus (siluridae) from the euphrates river in Turkey(Societe Francaise d'Ichtyologie, 1996) Ünlü E.[No abstract available]
