Ebook "Shallow lakes in a changing world: Proceedings of the 5th International Symposium on Shallow Lakes, held at Dalfsen, The Netherlands, 5–9 June 2005" have given us deeper insights into the functioning of food-webs in shallow waters, nutrient dynamics in open water, and in the complexities of interactions in littoral and pelagic regions, and of the sedimentwater interphase. We are now starting to implement the knowledge gained in order to rehabilitate some lakes, if not restore them.

The Quaternary Zarloukh Bentonite –Tuff (ZBT) deposit occurs within the Hemrin South Mountain, northern Iraq. The ZBT deposit occurs as depression-filling exposed on the erosional surface of the siliciclastic Pliocene Muqdadiya Formation and covered by an overburden of recent sediments. The thickness of the studied industrial bentonite bed is ~80−100 cm, occurring at the bottom of these depressions, covered by ~3−4 m thick bedded volcanic tuff, which also contains many 10–12 cm thick bentonite layers along its bedding planes.

The invasive brown bullhead (Ameiurus nebulosus (Lesueur, 1918)) has been present in Europe since the late 19th century, but there is still a lack of reliable information about its distribution in Europe and the condition of its population. A long-term study (from 2000 to 2011) in three shallow lakes in Central Europe (eastern Poland) was carried out to determine the occurrence of the brown bullhead and its participation in the fish community. The brown bullhead was present in almost all the sampling fishing in all the lakes studied (Ci = 72%–82%).

The objective of this study is to provide information on the parthenogenetic Artemia populations in some hypersaline lakes of Anatolia (Tuz, Bolluk, Tersakan, and Acıgöl). Sampling studies were performed for abiotic factors and population parameters between November 2009 and October 2010. During the survey we focused on the local Artemia populations to investigate population dynamics, reproduction, brood size, and cyst and naupliar biometrics. Generally, the Artemia habitats in Anatolia were relatively shallow, and thus they were subject to major seasonal fluctuations.

The late Cenozoic extensional deformation formed several NE-trending fluvio-lacustrine basins in SW Anatolia, filled by alluvial, fluvial and lacustrine deposits. Among them, the Acıgöl basin , is notable for its tectono-sedimentary development of a prominent shallow-perennial playa-lake setting. The basin initially subsided to receive coarse-clastic alluvial deposits, merging into fluvial systems and central shallow lakes.

Temporal changes in the species composition, seasonal abundance, and diversity of net phytoplankton (NPP) were investigated in relation to some environmental characteristics of the water and sediment of Lake Krishnasayer, an ancient man-made shallow freshwater lake, located at Burdwan, India, between January and December 2003.

The relationships between water discharge, temperature, pH, conductivity, turbidity, nitrate, ammonium, phosphate and the seasonal dynamics of phytoplankton assemblages of one of the inlets, which is a source of waste for the lake, and the sole outlet of the shallow hypertrophic Lake Manyas, Turkey, were studied from January 2003 to August 2005.

The aim of this research was to compare the phytoplankton structure on the basis of environmental variables and test the Q assemblage index based on phytoplankton functional groups in two shallow Mediterranean lakes [Lake Taşkısığı (LT) and Lake Little Akgöl (LLA)] in the north of Turkey.

The chlorococcal chlorophyte community structure and seasonal variations in terms of species composition and abundance of dominant species in Tatlı, Gıcı, Liman, and Cernek lakes (Samsun, Turkey) were investigated between 1996 and 2003.

Limitations on the availabilityof water resourcesareamong the greatest challenges facing modern society, despite the fact that roughly 70% of the earth’s surface is covered by water. Human society depends on liquid freshwater resources to meet drinking, sanitation and hy‐ giene, agriculture, and industry needs.Roughly 97% of the earth’s surface and shallow sub‐ surface water is saline and about 2% is frozen in glaciers and polar ice.

Nitrogen contamination may come from a variety of sources: municipal sewage, animal manure, atmospheric deposition, biological N fixation, soil organic N, and/or nitrogen fertilizers. The consequences of contamination in a specific water body will depend upon the amount of contamination from all sources and characteristics of the receiving waters. Shallow rivers, wetlands, lakes, and reservoirs, have some capacity to remove nitrogen by microbial denitrification.

UNIT 2 : BIOMES AND ECOSYSTEMS Influenced by latitude, elevation, and associated moisture and temperature regimes, terrestrial biomes vary geographically from the tropics through the arctic and include various types of forest, grassland, shrub land, and desert. These biomes also include their associated freshwater communities: streams, lakes, ponds, and wetlands. Marine environments, also considered biomes by some ecologists, comprise the open ocean, littoral (shallow water) regions, benthic (bottom) regions, rocky shores, sandy shores, estuaries, and associated tidal marshes.
