The meiofauna of a New South Wales sandy beach: an introduction to the meiofauna of Australian ocean beaches

Abstract

The very limited published work on the meiofauna of Australian sandy ocean beaches is reviewed, particularly the relevant taxonomic publications. The intertidal meiofauna at Broulee beach, NSW, was investigated. Meiofauna was extracted from three replicate samples of the top 20cm of sand in January 2000. Three adjacent consecutive 20cm samples were taken from 0-60cm at the same time. The samples were taken with a 90mm diameter corer holding about 1 litre of wet sand. Another similar set of six cores was taken from about the same mid-tide position in August 2001. Meiofauna was identified, counted and quantitatively estimated. The dominant faunal groups were nematodes, copepods, and ostracods. The nematodes were by far the most taxonomically diverse and were identified to species, though often only named to genera. Nematode genera were assigned to feeding categories. Also included in the meiofaunal collection were turbellaria, gastrotrichs, archiannelids, oligochaetes, tardigrades, acarina and collembola. These groups were identified to the level made possible by the pertinent taxonomic literature. No statistical evidence was found of differences between the fauna in summer and winter or with depth in the top 60cm of sand.
