Meiobenthos in marine coastal sediments

Geological Society, London, Special Publications, 2013
Abstract The term meiobenthos refers to a group of invertebrate organisms that are intermediate in size between macro- and microfauna, and inhabit all sediment types in all marine environments and in all climatic zones. They may occur at enormously high densities of millions of individuals per square metre; this means that 10 cm

A new quantitative sampler for the meiobenthos

Ophelia, 1964
Abstract The meiobenthos, which comprises animals with a body length of approximately 0.2–2.0 mm, can be sampled quantitatively by means of a new untraditional grab which is described and figured. It cuts out a square of 150 cm2 of the upper 2–3 cm of the substratum and keeps the sample in a bag of nylon gauze. The instrument has worked successfully in

Meiobenthos of Sub-Littoral Muds

Journal of the Marine Biological Association of the United Kingdom, 1964
SUMMARYMeiobenthos, here defined as metazoans passing through a ½ mm screen, is described from core samples collected on muddy grounds at 100-140 m depth in the North Sea and off the west coast of Scotland between February 1962 and August 1963.Sixteen cores of 2·2 cm diameter were collected from Loch Nevis, and 14 from the Fladen ground.

The role of meiobenthos in lake ecosystems

Aquatic Ecology, 2002
It is shown that meiobenthos plays an important role in the secondary production by zoobenthos in lakes, as well as in the degradation of organic matter. In large lakes (Lake Ladoga, Lake Onega, Lake Paijanne, Lake Constance), the ratio of meiobenthic production to the production of macrobenthos is on average 50–61%.

The importance of turbellarians in the marine meiobenthos: a review

Hydrobiologia, 1986
Recent data and opinions on meiofaunal ecology are briefly reviewed; and from scattered data, the place of turbellarians in the meiobenthic community is discussed. Turbellarian diversity, density, and biomass are higher in sandy habitats than in muddy bottoms.

Deficiency of Gravity Corers for sampling Meiobenthos and Sediments

Nature, 1971
GRAVITY corers are widely used1,2 for the collection of the smallest marine metazoans (meiofauna) from subtidal grounds, and it has been generally accepted that cores which appear undisturbed give reasonably representative samples. But, after comparing gravity cores with samples collected by SCUBA divers, I suggest that this is not so.

The Meiobenthos of Fjords: A Review and Prospectus

1980
The marine meiobenthos is a diverse assemblage of small (0.5 – 0.1 mm) metazoans living on and in the bottom of the sea. It includes most invertebrate phyla, especially nematodes and copepod crustaceans. Although meiofauna are ubiquitous, abundant and productive members of benthic ecosystems, their ecology in deep-water fjords is little studied.

Spatial and temporal effects of organic enrichment on meiobenthos

1995
Meiofauna assemblages were studied along putative organic enrichment gradients at two marine salmon farms: Loch Ewe, Scotland, U.K. and Nubeena, SE Tasmania, Australia; and a sewage outfall: Sandy Bay, SE Tasmania. The broad objective was to identify any general meiofauna responses to organic enrichment. 1.

An improved detritus-sledge for collecting meiobenthos

Ophelia, 1964
Abstract A simple detritus-sledge for collecting animals of the meio- and small macrobenthos from level sea-bottoms is described and figured. Its high degree of efficiency - due to a chain which stirs up the surface of the bottom ahead of the net-opening - is exemplified.

Meiobenthos communities of some subarctic lakes

Hydrobiologia, 1997
Meiobenthos communities of 19 relatively small tundra lakes (area 0.2–320 ha) were studied during summer seasons of 1986–1988 and 1993. The lakes are located in the northeastern region of European Russia. All lakes are separated into deep (with mean depth from 2.0 to 8.0 m) and shallow ones (mean depth is less than 1.5 m).
