meiofaunan.

Brit.

/ˌmʌɪəʊˈfɔːnə/, U.S.

/ˌmaɪoʊˈfɔnə/,

/ˌmaɪoʊˈfɑnə/

Origin: Formed within English, by compounding. Etymons: meio- comb. form, fauna n.

Etymology: < meio- comb. form + fauna n., after meiobenthos n. Compare earlier microfauna n. and macrofauna n.

Ecology.

With plural agreement: animals which are intermediate in size between macrofauna and microfauna; esp. the smallest visible interstitial benthic or soil invertebrates up to about a millimetre in length; spec. those of a particular habitat, region, etc. Also (with singular agreement): a group, class, community, or list of such animals.

1950 Proc. Royal Entomol. Soc. London C. 15 8 He [sc. P. Murphy] suggested that the term meiofauna might be used to describe these and other organisms which lie between the micro- and macro-fauna.

1953 P. W. Murphy in Jrnl. Soil Sci. 4 155 The writer would prefer the term meio- instead of meso-fauna as the transition from micro- to meso-fauna is much more gradual and less easily defined than that from meso- to macro-fauna.

1973 Nature 30 Mar. 323/2 Ostracods and nematodes were the most widely distributed and active members of the meiofaunas.

1988 Nature 3 Mar. 73/1 These results provide the first evidence that deep-sea meiofaunal organisms can respond to low-intensity ecological disturbances of the kind caused by phytodetritus deposition.
