Meiofauna define a diverse assemblage of minute invertebrates generally associated with the benthos, or bottom, of many streams and rivers. Meiofauna can be considered intermediaries between microbes and macroscopic organisms in stream food webs. In this chapter, we detail how to sample, identify, and quantify these tiny animals.

Meiofauna and the origins of the Metazoa
Zoological Journal of the Linnean Society, 1989Possible alternative habitats and life-styles of the original metazoan are considered. It is argued from the dominance of the benthic habitat in present-day groups that the original metazoan habitat was benthic rather than planktonic. Similarly, plesiomorphic metazoan taxa tend to be holobenthic rather than pelago-benthic. It is therefore probable that

Aerobic Microbes and Meiofauna
1981Heterotrophic microorganisms in a detritus-based salt-marsh system are a major link in the mineralization and transformation of organic matter. The biomass and activity of heterotrophic microorganisms in the salt-marsh estuary at Sapelo Island have been examined with regard to both habitat and metabolic rotes.

The effects of meiofauna on settling macrofauna: meiofauna may structure macrofaunal communities
Oecologia, 1983When macrofaunal larvae and juveniles recruit into the benthos, they are in the same size catagory as the meiofauna. These small size classes have been consistently ignored in macrofaunal studies despite the increasingly accepted idea that communities are structured not only by interactions between adults, but also by interactions which occurred when ...

The structure of meiofauna communities
Sarsia, 1978Abstract Although the meiofauna covers a diverse range of taxa, all are convergent in that (by definition) their size range is relatively restricted. Conceivably this could lead to community structure being organized in a different way to that in macrofauna.

Interactions of lead with sediments and meiofauna
Marine Pollution Bulletin, 1976Abstract Harpactacoid copepods and Turbellaria appear to be the most sensitive faunal groups in surface sand meiofauna when subjected to contamination by lead; in subsurface sand, nematodes are found to be the most sensitive group. Simple laboratory attempts to assess lead partitioning in littoral sand gave variable results and the problems and ...

Addressing biodiversity shortfalls in meiofauna
Journal of Experimental Marine Biology and Ecology, 2018Technological advances throughout different fields of research have enhanced our understanding of biodiversity, especially for meiofaunal organisms, which are notoriously difficult to study because of their small size. Scanning and transmission electron microscopy, together with confocal laser scanning microscopy, has increased the amount of external ...

Studies on the meiofauna of Sagar Island
Proceedings: Animal Sciences, 1983Mean number of total meiofauna individuals in the intertidal estuarine sediments around the island ranged from 1/10 cm2 to 517/10 cm2. Nematodes and copepods were the dominant taxa comprising over 80% of the total fauna. Higher meiofaunal densities occurred over the lower shore.

The meiofauna of a flatfish nursery ground
Journal of the Marine Biological Association of the United Kingdom, 1973The meiofauna was studied over a 10-year period on a flatfish nursery ground between the high-water mark and a depth of 10 m below low-water springs.The sediment was well sorted sand, with median diameter from 210 to 279 μ in the intertidal area and 160 to 208 μ in the subtidal.
