The littoral zoobenthos

1981
The littoral substrate and its associated zoobenthos is described from a number of samples collected around the shorelines of these five lochs, during autumn 1977. Further samples were taken from autumn 1977 to autumn 1978 to provide comparative information on species diversity, seasonality, growth, life-cycles and depth distribution of littoral ...

The profundal zoobenthos

1981
Little information was previously available on the sediments and invertebrate faunas of the deep waters of the large lochs of Scotland, except Loch Lomond. This paper reviews the published data and presents new information for the five largest lochs. The profundal sediments are characterised by very fine particle sizes (high fractions of clay and silt)

Eutrophication and Zoobenthos dynamics

Ophelia, 1995
The possible effects of eutrophication on benthic dynamics are discussed based on the Pearson-Rosenberg Model that describes the effects of organic enrichment on qualitative characteristics of benthic communities. Depending on the amount of organic matter reaching the sediments, the model describes three successive states: a) slight increases in ...

Assemblage patterns and community structure of macro-zoobenthos and temporal dynamics of eco-physiological indices of two wetlands, in lower gangetic plains under varying ecological regimes: A tool for wetland management

Ecological Engineering: The Journal of Ecotechnology, 2019
Wetlands are rich biological resources and support livelihood and nutritional security to a huge populace globally. In the present study, two ecologically distinct floodplain wetlands viz., Khalsi and Akaipur located in the sub-basin of Jamuna river in ...

Remediation of Eutrophic Water Body by Zoobenthos

Advanced Materials Research, 2011
To study the temperature factor affecting nutrient release of Cipangopludina Chinensis, laboratory simulation experiments were carried out, and other traits of Cipangopludina Chinensis, such as the effects of nitrogen cycling, phosphorus cycling, suspended substance in water column.

Modelling production and biomasses of zoobenthos in lakes

Aquatic Ecology, 2003
This work presents a dynamic model to predict zoobenthos in lakes. The model has been developed within the framework of a more comprehensive lake ecosystem model, LakeWeb, which also accounts for the following functional groups of organisms, phytoplankton, bacterioplankton, two types of zooplankton (herbivorous and predatory), macrophytes, prey fish ...

Influence of habitat degradation on the fatty acid profiles of fish, microalgae, and zoobenthos in a river ecosystem

Chemical engineering research & design, 2019
This study was conducted to assess the effect of heavy metals (Cd, Hg, Cu, Mn, Zn, Pb, Cr, and Sn) on the fatty acid profiles of Catla catla, Labeo rohita, and Cirrhinus mrigala collected from two polluted sites in the Chenab River and Jhelum River (non ...

Zoobenthos der oberen Rur

Decheniana : Verhandlungen des Naturhistorischen Vereins der Rheinlande und Westfalens, 1978
Das Zoobenthos der oberen Rur wurde an 7 Probestellen zwischen der belgisch-deutschen Grenze und Hoven bei Düren qualitativ und semi-quantitativ untersucht und - soweit möglich - bis zur Art bestimmt. 63 Arten wurden festgestellt und werden nach ihrer Verteilung im Bachlängsschnitt beschrieben.

Study on zooperiphyton and zoobenthos of a small river

Inland Water Biology, 2008
The special traits of zooperiphyton and zoobenthos structures in a small river were studied. Under conditions of maximal proximity of niches, these groups of invertebrates retain taxonomic and ecological heterogeneity. Differences in zooperiphyton and zoobenthos taxonomic structures are most pronounced in terms of presence of dipterans, oligochetes ...

Die Zoobenthos‐Gesellschaften des Piburger Baches (Ötztal, Tirol). The Zoobenthos Assemblages of Piburger Bach (Oetztal, Tyrol)

Internationale Revue der gesamten Hydrobiologie und Hydrographie, 1978
AbstractPiburger Bach is a short, spring‐fed lake affluent. The macrozoobenthos of this stream has been studied both qualitatively and quantitatively. More than 15,000 specimens of invertebrates, including all developmental stages of insects, were collected; a high proportion of these was identified to the genus or species level.
