Switching Between Deposit and Suspension Feeding in Coastal Zoobenthos

2001
This chapter, consisting of an overview followed by two sub chapters each dealing with a specific example, attempts to provide current insight into possible switching between deposit and suspension feeding in coastal zoobenthos. The examples are two common inhabitants of shallow waters, the polychaete Nereis diversicolor and the bivalve Macoma balthica.

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 ...

Riffle zoobenthos in streams receiving acid mine drainage

Water Research, 1972
Abstract The bottom fauna of a stream polluted by acid mine drainage, was studied, using the standard methods of sample collecting. In localities immediately influenced by mine drainage, where very low pH values and high acidities prevail, the effect of acid mine wastes on the ecology and composition of the benthic fauna is, in general, similar to ...

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 ...

Mercury and chlorinated hydrocarbons in zoobenthos of Lake Päijänne, Finland

Archives of Environmental Contamination and Toxicology, 1979
The average amounts of mercury, PCBs, and sigma DDT (primarily DDE), found in macrozoobenthos, on the wet basis, in Lake Päijänne, Finland, for the time period 1972-1974, were 79 ng/g, 29 ng/g, and 8 ng/g, respectively. Lindane was found in negligible amounts in only 2% of the samples examined; aldrin was present in 10% of the samples; no dieldrin was ...

[Effects of grazing on zoobenthos community in beach].

Ying yong sheng tai xue bao = The journal of applied ecology, 2007
In May (spring) and October (autumn) 2005, the effects of grazing on the zoobenthos community in Chongming Dongtan wetland of Shanghai were investigated. A total of 3 transects including 90 sampling plots were set up. Transects I and II were in feeding area, and transect III was in non-pasture area.
