Abstract

The meiofauna was investigated on a sandy ocean beach, usually exposed to strong surf, in southeast Australia. Samples were taken from high tide level to 5 metres below low tide level at a beach previously damaged by a storm and re-established by natural wave action. The meiofauna were counted to major taxa, with nematodes identified to genus or species. Differences were observed between the subtidal and intertidal samples. Some species or higher taxa are restricted to either the subtidal or the intertidal zone while others extend across both zones. A majority of the genera are cosmopolitan, but species appear to be unique to Australia. The results suggest that when a beach is rebuilt with fresh sand following a storm, re-colonization is a taxonomically selective process. However, the mechanisms of selection are currently unknown.
