Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation. We performed a pan-European lake mesocosm experiment on periphyton colonization covering five countries along a north/south geographical/temperature gradient (Estonia, Germany, Czech Republic, Turkey, and Greece). Periphyton biomass on artificial polypropylene strips exposed at 50 cm water depth at low and high nutrient regimes (with mean total phosphorus concentration of 20 and 65 mu g L-1, respectively) was compared during mid-summer. No significant effect of nutrient loading on periphyton biomass was observed as nutrient concentrations in the mesocosms were generally above limiting values. Water temperature significantly enhanced summer periphyton biomass development. Additionally, direct and indirect top-down control of snails and fish emerged as a significant factor in periphyton biomass control.

Effects of climate change on biodiversity: a case study on four plant species using distribution models Beton, Damla; Bilgin, Cemal Can; Department of Biology (2011) Conservation strategies are mainly focused on species existing in an environment shaped by natural and anthropogenic pressures. Yet, evidence shows that climate is changing faster than ever and expected to continue to change in the near future, which can be devastating for plants with restricted ranges. Turkey harbors many endemic species that might be affected from these changes. However, available data is scarce and biased, complicating the anticipation of future changes. Aim of this study is to improve o...
Impact of zooplankton grazing on phytoplankton in north temperate coastal lakes: changes along gradients in salinity and nutrients Christensen, Inge; Pedersen, Lisbeth Kjæreby; Søndergaard, Martin; Lauridsen, Torben L.; Tserenpil, Sh.; Richardson, Katherine; Alves Amorım, Cıhelıo; Pacheco, Juan Pablo; Jeppesen, Erik (2022-10-01) Zooplankton grazing at similar nutrient levels is generally regarded as lower in brackish than in freshwater lakes, but experimental evidence of this is lacking. Accordingly, we conducted short-term zooplankton grazing experiments in bottles with water from 12 Danish brackish lakes covering a large gradient in salinity (0.3-17.4 parts per thousand) and nutrient concentrations as well as with water from 24 mesocosms established in the same area with various salinities (0.5-12 parts per thousand), two nutrien...
Changes of Eutrofication Indicator Parameters (TP, DIN, Chl-a and TRIX) in the Cilician Basin (Northeast Mediterranean) TUĞRUL, SÜLEYMAN; Uysal, Zahit; Erdogan, Emine; Yucel, Nebil (2011-01-01) Eutrophication processes and changes in coastal ecosystem are determined by the coastal/open sea interactions and rates of nutrient pollution. The Cilician Basin shelf waters are affected not only by intense industrial activities and increased population, but also by complex atmosphere-sea-land interactions. There is a recognizable difference between water qualities of Mersin bay coastal and the Cilician open waters depleted in nutrients. Eutrophic conditions have developed in the eastern bay shallow waters...
Effects of Crucian Carp (Carassius auratus) on Water Quality in Aquatic Ecosystems: An Experimental Mesocosm Study Huang, Yehui; Mei, Xueying; Rudstam, Lars G.; Taylor, William D.; Urabe, Jotaro; Jeppesen, Erik; Liu, Zhengwen; Zhang, Xiufeng (MDPI AG, 2020-5-19) The presence of omnivorous fish is known to affect aquatic ecosystems, including water quality. The effect, however, depends on the species in question, and our knowledge is limited on the effect of omnivorous crucian carp (Carassius auratus), a common and often the most numerous fish species in eutrophic shallow lakes in China. We conducted a 70-day outdoor experiment in mesocosms with and without crucian carp to examine whether this species adversely affects water quality by increasing the levels of total...
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...
