| Abstract: | Studies designed to describe the structure of soft bottom meiobenthic communities have used diverse sorting methods, thus making the comparison of results difficult. This study compared sorting specimens using the manual and centrifuge density gradient sorting methods, for two deep-sea depth zones continental slope (1630–1860 m) and abyssal plain (3720–3830 m)] in the southwestern Gulf of Mexico. The manual sorting method produced more taxonomic groups and higher abundance and biomass values, compared to the differential density Ludox-centrifuge sorting method. The results obtained from the two sorting methods suggest that distribution patterns of deep-sea meiofaunal samples can be an artefacts of the sorting. |
