Micro‐Meiofaunal Community Structure and Nematode Diversity in a Lagoonal Ecosystem (Fangataufa, Eastern Tuamotu Archipelago)

Mciofaunal assemblages in a semi‐closed Polynesian atoll have been assessed. High densities, numerous micro‐ and meiobenthic groups, and 62 diversified (H′= 2.64) nematode species occur. As a whole, the lagoonal habitat may be considered as homogeneous, its variability being controlled by oceanic inflows.
