Despite their potentially important role in ecosystem functioning, meiofauna are possibly the least studied animals associated with hard bottoms such as coral and sandstone reefs. A significant limitation in meiofauna research has been the lack of standardized sampling methods for species
inhabiting hard surfaces. To address this problem we tested four different sampling methods proposed for the reef meiofauna community: a suction pump at three different suction treatments (20 s, 1 min, and 5 min) and substrate scraping. Significant differences were observed in the abundance
of meiofauna groups, and the composition and diversity of Nematoda genera. The highest values were always generated by substrate scraping. We conclude that scraping is a more accurate method of sampling (among the methods tested) and we recommend the adoption of this method for future hard
bottom meiofauna studies.
