Zoobenthos of the drainage zone of Novosibirsk Reservoir

Contemporary Problems of Ecology, 2011
Zoobenthos of the basic biotopes in the drainage zone of Novosibirsk Reservoir has been studied for the first time. Its composition and quantitative characteristics on the dried areas are determined depending on the ground composition, duration of drainage, distance from the zone of permanent submergence, and location under the minimal level of the ...

Diet influence on mercury bioaccumulation as revealed by polyunsaturated fatty acids in zoobenthos from two contrasting environments: Chinese reservoirs and Swedish lakes

open access: yesScience of the Total Environment, 2021
The bioaccumulation of mercury (Hg) and polyunsaturated fatty acids (PUFA) in zoobenthos varies across aquatic food webs. In this field study, contents of total Hg (THg), methylmercury (MeHg) and PUFA were investigated in zoobenthos of Chinese reservoirs

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 ...

Filter-Feeding Zoobenthos and Hydrodynamics

2015
This chapter summarizes recent years' studies on zoobenthic filter feeding in the sea. General principles are extracted based on experiments and mathematical modeling, mainly from own studies in shallow temperate Danish waters, in order to present primary characteristics of the sophisticated interplay between benthic filter feeders and hydrodynamics ...

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.

Surface Zoobenthos

2003
Alpine glacial flood plains are highly dynamic systems with respect to both their environmental conditions and zoobenthic assemblages. Seasonal changes in the balance between glacial meltwater and groundwater contributions result in shifting patterns of spatial heterogeneity.

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 ...
