Development and testing of a prototype indicator-based tool for identification of potential problem areas for marine litter in Europe's seas Murray, Ciarán J.; van Bavel, Bert; Kıdeyş, Ahmet Erkan; Lusher, Amy L.; Reker, Johnny; Šubelj, Gašper; Andersen, Jesper H. (2023-12-20) We demonstrate a prototype multi-metric indicator-based assessment tool (i.e. Marine Litter Assessment Tool - MALT) for mapping and identification of ‘problem areas’ and ‘non-problem areas’ regarding the occurrence of mari...
Microplastic distribution in the surface water and sediment of the Ergene River Akdogan, Zeynep; Guven, Basak; Kıdeyş, Ahmet Erkan (2023-10-01) Rivers are major transport pathways for microplastics to reach the oceans. Although gained much attention over the last few years, there is still a relatively lack of knowledge on microplastics in rivers. This study aims t...
Morphology, Molecular Genetics and Potential Importance for Mucilage Events of the New Coccolithophorid Ochrosphaera neapolitana in the Sea of Marmara Eker-Develi, Elif; Tekdal, Dilek; Demet, Atıf Emre; Yıldız, Hüseyin Bekir; Kıdeyş, Ahmet Erkan (2023-03-01) The coccolithophorid Ochrosphaera neapolitana was reported for the first time from samples obtained during a large-scale mucilage event in the Sea of Marmara in May 2022 in a previous study. We also found this species in o...
Identification of Cutinolytic Esterase from Microplastic-Associated Microbiota Using Functional Metagenomics and Its Plastic Degrading Potential Adıgüzel, Ali Osman; Şen, Fatma; Könen-Adıgüzel, Serpil; Kıdeyş, Ahmet Erkan; Karahan, Arzu; Doruk, Tuğrul; Tunçer, Münir (2023-01-01) Plastic pollution has threatened biodiversity and human health by shrinking habitats, reducing food quality, and limiting the activities of organisms. Therefore, global interest in discovering novel enzymes capable of degr...
Riverine Microplastic Loading to Mersin Bay, Turkey on the North-eastern Mediterranean Ozguler, Ulku; DEMİR, AYDENİZ; Kayadelen, Gulsah Can; Kıdeyş, Ahmet Erkan (2022-07-01) Microplastics sampled downstream from a total of eight rivers were analysed as the first attempt to determine microplastic composition in rivers and load to Mersin Bay, in the north-eastern Mediterranean Sea. With a share ...
Population dynamics and ecology of the invasive veined rapa whelk, Rapana venosa in the southern Black Sea MUTLU, ERHAN; Kıdeyş, Ahmet Erkan; Şahin, Fatih; Erik, Gökhan; Aksu, Hakan; Erdem, Ercan; Karayücel, Sedat; Bat, Levent (2022-05-05) © 2022 Elsevier LtdSpatial and temporal changes in some ecological characteristics (i.e. biomass, abundance, morphometrics, sex-composition, growth parameters and population dynamics) of the invasive veined rapa whelk (Rap...
Marker pigments and carbon biomass of phytoplankton on the northeastern Mediterranean Sea coast Konucu, Merve; Eker-Develi, Elif; Örek, Hasan; Başduvar, Şehmuz; Kıdeyş, Ahmet Erkan (2022-05-01) © 2022 Elsevier B.V.Marker pigments are used to determine taxonomic composition and biomass of microalgae in different oceanic regions. However, sometimes discrepancies are encountered between microscopy and marker pigment...
