The macrobenthos of Sullom Voe
Proceedings of the Royal Society of Edinburgh. Section B. Biological Sciences, 1981SynopsisThe macrobenthos of Sullom Voe was investigated by grab sampling in 1976, 1977 and 1978. These surveys have provided data for future comparisons and have enabled a description to be made of the natural soft bottom macrobenthos of Sullom Voe in terms of species composition and abundance.The most common species encountered were Thyasira flexuosa,

[Bioturbation of macrobenthos on estuarine sediment].
Ying yong sheng tai xue bao = The journal of applied ecology, 2011By using microcosm tracer technique, the bioturbation of macrobenthos Helice tientsinensis, Nereis diversicolor, Bullacta exarata, and Cyclina sinensis on the sediment in Beitang Estuary of Tianjin, China was quantitatively studied. The bioturbation of test macrobenthos had obvious effects on the distribution of the sediment, and the effects differed ...

The macrobenthos of the river IJssel
Hydrobiological Bulletin, 1978This survey of the macrobenthos of the River IJssel, a branch of the River Rhine, was conducted in 1973, 1975, 1976 and 1977. The water quality was poor in 1973 and 1976 and relatively good in 1975 and 1977. The numbers of macroinvertebrate species and numbers of individuals in the stone samples taken from the jetties were lowest in 1976 and highest in

Macrobenthos and environmental characteristics of the Venice lagoon
Atti della Società dei Naturalisti e Matematici di Modena, 2007Composition, structure and distribution of macrozoobenthic communities in four areas of the Venice Lagoon were investigated. Polychaetes and oligochaetes were the most abundant groups, followed by crustaceans and dipterans and bivalve molluscs. Area differences turned out to be very significant with a maximum diversity index in the central-southern ...

Macrobenthos of the Novaya Zemlya Trough
Oceanology, 2010During the 54th cruise of the R/V Akademik Mstislav Keldysh the macrobenthos of the Novaya Zemlya Trough was studied using a Sigsby trawl along the submeridional transect near 75°30′N latitude at a depth range from 68 to 362 m. In total, 140 species of bottom animals were found.

Recovery of macrobenthos in defaunated tropical estuarine sediments
Marine Pollution Bulletin, 2011In the estuarine environment, hypoxia and/or anoxia have become a major cause of benthic defaunation and are strongly associated with increased eutrophication. Mesoscale field experiments were carried out to examine the recolonization and recovery time of macrobenthos after defaunation.

The historical development of studies on macrobenthic community ecology has been closely related to surveys of fjordic populations stemming from the classical work of Petersen and his successors in Danish areas. This relationship is not fortuitous since fjordic populations are rich, accessible and economically important as the basis of extensive ...

Organic pollution and the macrobenthos of Raritan Bay
Environmental Toxicology and Chemistry, 1984AbstractThe Raritan Bay—Lower New York Bay complex was surveyed to examine xenobiotic—sediment—benthic relationships. The macrofauna, sediment granulometry, extractable hydrocarbons, polychlorinated biphenyls (PCB) and polynuclear aromatic hydrocarbons (PAH) were surveyed concomitantly.

An investigation was conducted on the community structure of macrozoobenthos in the main stream of Songhua River in spring (April and May), summer (July and August), and autumn (from September to November), and the water quality of the main stream was assessed with biotic indices.

Trophic Structure of Abyssal Macrobenthos
1997Abstract The influence of feeding conditions on the large-scale distribution patterns of bottom-living invertebrates larger than 5 mm has been investigated in 228 bottom trawl samples collected by Russian research vessels from depths of 3000 to 6000 m in the Pacific and Indian Oceans.
