Water level and submerged macrophytes are critical players for the functioning of shallow lake ecosystems; understanding how waterbird communities respond to changes in both can have important implications for conservation and management. Here, we evaluated the effects of changes in water level and submerged macrophyte status on wintering waterbird community size, functional group abundances, functional diversity (FD), and community assembly by using a dataset compiled over 50 years.

Assessment of the impacts of future climatic variations and anthropogenic activities on Burdur Lake levels Kılıç Germeç, Hatice; Yazıcıgil, Hasan; Department of Geological Engineering (2023-1-24) Lake water levels naturally fluctuate due to imbalances in water inputs and outputs. However, lake hydrologic regimes may be altered by the impacts of climatic factors and human interventions, as in Burdur Lake. The Burdur Lake level has continuously decreased since the beginning of the 1970s. In this study, in order to quantify the loss/gain relationship between the aquifer and the Burdur Lake and specify the potential causes and consequences for the lake level decline, a 3-D numerical groundwater flow mod...
Impact of nutrients and water level changes on submerged macrophytes along a temperature gradient: A pan-European mesocosm experiment Ersoy, Zeynep; Scharfenberger, Ulrike; Baho, Didier L.; Bucak, Tuba; Feldmann, Tonu; Hejzlar, Josef; Levi, Eti E.; Mahdy, Aldoushy; Noges, Tiina; Papastergiadou, Eva; Stefanidis, Konstantinos; Sorf, Michal; Sondergaard, Martin; Trigal, Cristina; Jeppesen, Erik; Beklioğlu, Meryem (Wiley, 2020-09-01) Submerged macrophytes are of key importance for the structure and functioning of shallow lakes and can be decisive for maintaining them in a clear water state. The ongoing climate change affects the macrophytes through changes in temperature and precipitation, causing variations in nutrient load, water level and light availability. To investigate how these factors jointly determine macrophyte dominance and growth, we conducted a highly standardized pan-European experiment involving the installation of mesoc...
Impact of alternating wet and dry periods on long-term seasonal phosphorus and nitrogen budgets of two shallow Mediterranean lakes Coppens, Jan; ÖZEN, ARDA; Tavsanoglu, U. Nihan; Erdogan, Seyda; Levi, Eti E.; Yozgatlıgil, Ceylan; Jeppesen, Erik; Beklioğlu, Meryem (2016-09-01) The water balance, with large seasonal and annual water level fluctuations, has a critical influence on the nitrogen and phosphorus dynamics of shallow lakes in the semi-arid climate zone. We constructed seasonal water and nutrient budgets for two connected shallow lakes, Lakes Mogan and Eymir, located in Central Anatolia, Turkey. The study period covered 20 years with alternations between dry and wet years as well as restoration efforts including sewage effluent diversion and biomanipulations in Lake Eymir...
Interactions of water and sediment phosphorus in Lake Eymir Plevneli, Tolga; Aksoy, Ayşegül; Sanin, Selim L.; Department of Environmental Engineering (2013) A detailed study is held in Lake Eymir, a shallow eutrophic lake, investigating the phosphorus concentrations in water and the bottom sediment. Water depth, secchi depth, TSS, sediment soluble total phosphorus, sediment soluble PO4-P, Chl-a , TKN, NH4-N, NO2-N, NO3-N, alkalinity, temperature, pH, conductivity, dissolved oxygen, turbidity and PAR parameters are monitored for 21 months and Principal Component Analysis (PCA) is applied to identify trend of phosphorus concentration in water column. Results indi...
Similarity between contemporary vegetation and plant remains in the surface sediment in Mediterranean lakes Levi, Eti E.; Cakiroglu, Ayse I.; Bucak, Tuba; Odgaard, Bent V.; Davidson, Thomas A.; Jeppesen, Erik; Beklioğlu, Meryem (2014-04-01) Aquatic macrophytes are commonly used to assess the ecological condition of lakes. Little is known, however, about long-term macrophyte dynamics in shallow lakes. In the absence of historical data, the remains of macrophytes (fruits, seeds and vegetative fragments) found in lake sediments may provide just such information. In order to interpret confidently past change in aquatic plant communities from their sedimentary remains, it is vital to establish the similarity between the contemporary and fossil asse...
