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

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 ...

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 ...
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 effect of reed beds on wave attenuation and suspended sediment concentration

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 alternating wet and dry periods on long-term seasonal phosphorus and nitrogen budgets of two shallow Mediterranean lakes

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...
