EFFECTS OF WET AND DRY PERIODS ON LONG TERM PHOSPHORUS AND NITROGEN BUDGETS AND THEIR RELATIONSHIPS WITH LAKE NUTRIENT AND CHLOROPHYLL-A CONCENTRATIONS Filiz, Nur; Yıldız, Dilvin; Yalçın, Gülce; Beklioğlu, Meryem (2025-07-10) The functioning of shallow lakes, which are extremely susceptible to variations in precipitation, evaporation, and water inflows and outflows due to their shallow form, depends heavily on hydrology. Water level changes in ...
Allochthonous matter quality regulates functionality of lake zooplankton Yıldız, Dilvin; Yalçın, Gülce; Calderó-Pascual, Maria; Metin, Melisa; Kavak, Pınar; Dede, Cemreay; Spoljar, Maria; Gottstein, Sanja; McCarthy, Valerie; Nejstgaard, Jens Christian; Jeppesen, Erik; Ger, Kemal Ali; Beklioğlu, Meryem (2025-01-01) While numerous studies have investigated the effects of climate-induced increase of allochthonous matter (AM), the differential impacts of multiple AM sources on plankton dynamics are poorly understood. Here, we investigat...
Quality matters: Response of bacteria and ciliates to different allochthonous dissolved organic matter sources as a pulsed disturbance in shallow lakes Yalçın, Gülce; Yıldız, Dilvin; Calderó-Pascual, Maria; Yetim, Sinem; Şahin, Yiğit; Parakatselaki, Maria-Eleni; Avcı, Feride; Karakaya, Nusret; Ladoukakis, Emmanuel D.; Berger, Stella A.; Ger, Kemal Ali; Jeppesen, Erik; Beklioğlu, Meryem (2024-03-15) Shallow lake ecosystems are particularly prone to disturbances such as pulsed dissolved organic matter (allochthonous-DOM; hereafter allo-DOM) loadings from catchments. However, the effects of allo-DOM with contrasting qua...
MOGAN ve EYMİR GÖLLERİ UZUN DÖNEMLİ SU ve BESİN TUZU BÜTÇELERİ Beklioğlu, Meryem; Yalçın, Gülce; Tavşanoğlu, Ülkü Nihan; Erdoğan, Şeyda; Jeppesen, Erik; Filiz, Nur; Bucak, Tuba; Coppens, Jan ; Çakıroğlu, A. Idil ; Levi, Eti E.; Özen, Arda (2023-11-01)
Factors driving the breeding microhabitat preferences of two endangered ducks in a shallow lake as revealed by a multidisciplinary approach Özgencil, İbrahim Kaan; Mercan, Deniz; Yaprak, Gencer; Genç, Gülümser; Özsoy, Dilan Melisa; Uslu, Alaz; Soyluer, Melisa; Korkmaz, Mustafa; Gülen, Berkay; Arıkan, Metehan; Ünal, Esra Mine; Keskin, Emre; Alkan, Sedef; Budak, Defne; Gül, Şeyma; Kıran, Hilal; Avcı, Feride; Filiz, Nur; Yalçın, Gülce; et.al.

Effects of a microplastic mixture differ across trophic levels and taxa in a freshwater food web: In situ mesocosm experiment Yıldız, Dilvin; Yalçın, Gülce; Jovanović, Boris; Boukal, David S.; Vebrová, Lucie; Riha, Derya; Stanković, Jelena; Savić-Zdraković, Dimitrija; Metin, Melisa; Akyürek, Yasmin Naz; Balkanlı, Deniz; Filiz, Nur; Milošević, Djuradj; Feuchtmayr, Heidrun; Richardson, Jessica A.; Beklioğlu, Meryem (2022-08-25) © 2022The ubiquitous presence of microplastics (MP) in aquatic ecosystems can affect organisms and communities in multiple ways. While MP research on aquatic organisms has primarily focused on marine ecosystems and laborat...
Double Trouble: Warmin and dissolved organic carbon (DOC) disturbance on microbial loop Yalçın, Gülce; Yıldız, Dilvin; Yetim, Sinem; Kuorsioti, Sevasti; Hasnain, Sarah; Jeppesen, Erik; Beklioğlu, Meryem (2022-08-08)
The importance of allochthonous organic matter quality when investigating pulse disturbance events in freshwater lakes: a mesocosm experiment Caldero-Pascual, Maria; Yildiz, Dilvin; Yalçın, Gülce; Metin, Melisa; Yetim, Sinem; Fiorentin, Claudia; Andersen, Mikkel Rene; Jennings, Eleanor; Jeppesen, Erik; Ger, Kemal Ali; Beklioğlu, Meryem; McCarthy, Valerie (2021-11-01) Extreme precipitation is occurring with greater frequency and intensity as a result of climate change. Such events boost the transport of allochthonous organic matter (allo-OM) to freshwater ecosystems, yet little is known...
Combined bottom-up effects of DOC and top-down effects of zooplankton with contrasting traits on phytoplankton biomass and composition Metin, Melisa; Yetim, Sinem; Yıldız, Dilvin; Yalçın, Gülce; Caldero Pascual, Maria; Fiorentin, Claudia; Beklioğlu, Meryem; Ger, Kemal Ali (2021-04-13)
Effects of dissolved organic carbon and zooplankton grazing pressure on bacteria and ciliates Yetim, Sinem; Metin, Melisa; Yıldız, Dilvin; Yalçın, Gülce; Caldero Pascual, Maria; Fiorentin, Claudia; Beklioğlu, Meryem; Ger, Kemal Ali (2021-04-13)
