1. Recent experimental and field studies on temperate shallow lakes indicate that nitrogen may play a greater role in their functioning than previously thought. Several studies document that abundance and richness of submerged macrophytes, both central in shallow lake ecology, may decrease with increasing nitrogen loading, especially at high phosphorus levels. However, the role of nitrogen in warm lakes with fluctuating water regimes remains to be described in detail.

Inferring conductivity and eutrophication in Turkish shallow lakes by using subfossil Diatoms Bezirci, Gizem; Sayer, Carl; Levi, Eti; Çakıroğlu, İdil; Bennion, Helen; Beklioğlu, Meryem (2016-08-31) In recent years, paleolimnologists have the ability of making accurate environmental predictions using high quality data sets through the help of modern techniques and analytical methods for answering questions about past and present status of freshwater environments. Diatoms play an important role in freshwater ecosystems as being good indicators of water quality and they provide valuable information about current and past status of lakes due to their high sensitivity about shifts in trophic status of the ...
Role of hydrology, nutrients and fish predation in determining the ecology of a system of shallow lakes Özen, Arda; Beklioğlu, Meryem; Department of Biology (2006) In this study, the hydrology and physical, chemical and biological variables of a shallow lake system including the Lakes Mogan and Eymir between 1997-2005 were evaluated. In Lake Eymir, a biomanipulation study was conducted between August, 1998 December, 1999. Upon biomanipulation, Lake Eymir shifted to clearwater state with submerged vegetation domination during 2000-2003. However, in 2004, the lake shifted back to algae-dominated turbid state since the buffer mechanisms provided by submerged plants were...
The influence of nutrient loading, climate and water depth on nitrogen and phosphorus loss in shallow lakes: a pan-European mesocosm experiment Coppens, Jan; Hejzlar, Josef; Sorf, Michal; Jeppesen, Erik; Erdogan, Aeyda; Scharfenberger, Ulrike; Mahdy, Aldoushy; Noges, Peeter; Tuvikene, Arvo; Baho, Didier L.; Trigal, Cristina; Papastergiadou, Eva; Stefanidis, Kostas; Olsen, Saara; Beklioğlu, Meryem (2016-09-01) Losses of phosphorus (P) and nitrogen (N) have important influences on in-lake concentrations and nutrient loading to downstream ecosystems. We performed a series of mesocosm experiments along a latitudinal gradient from Sweden to Greece to investigate the factors influencing N and P loss under different climatic conditions. In six countries, a standardised mesocosm experiment with two water depths and two nutrient levels was conducted concurrently between May and November 2011. Our results showed external ...
The effect of reed beds on wave attenuation and suspended sediment concentration Oğuz, Elif; Koroglu, Aysun; Kabdaşlı, Mehmet Sedat (Coastal Education and Research Foundation, 2013-01-01) The effect of emergent and submerged vegetation on uniform and oscillatory flow conditions has been intensively studied by researchers in the last two decades. It has been determined that vegetation affects wave characteristics and cause wave attenuation especially in shallow waters where wave orbitals are in interaction with vegetation. Consequently they affect sediment deposition and resuspension acting as a sink. The aim of this study is to determine wave attenuation due to vegetation, and to identify th...
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...
