摘要: Free-living marine nematode diversity was analyzed between Avicennia marina and Rhizophora mucronata mangrove covers of the Vellar Estuary (southeast coast India). A total 4,976 specimens free-living nematodes were collected in 56 species. Comparatively, a higher species richness obtained for A. (52 species) than R. (44 species), whereas 40 commonly existed both covers. density found sediments sandy nature, there lower organic carbon compared to silt/clay composition; epigrowth feeders dominant over other feeding groups based on enrichment surface sediments. Principal component analysis clearly explained relationship environmental parameters various months. Higher R values similarities revealed significant differences assemblages months, it quite evident by non-metric multidimensional scaling. Diversity indices showed dry RELATE serial changes composition biotic abiotic variables clarified using BIO-ENV procedure.
