The Zostera Meadows as a habitat for meiofauna

We found that the Zostera noltii meadows support a habitat for a diverse gastropod and copepod fauna. The copepod fauna comprises both species specialised to live on the Zostera leaves as well as strictly meiobenthic species (Antajan, 1998 DEA thesis Université Bordeaux 1). A transect was studied from a dense Z. noltii vegetated site to a bare sandy sediment, linking microelectrode measurements with meiofaunal studies. In the Z. noltii beds a deeper oxygen penetration correlated with a higher meiofaunal biodiversity compared to the bare sandy sediment site (Colangelo et al., Extended Report, Vol. I, p. 273). Sulphide tolerance of the dominant benthic copepod species Mysochra pontica is intermediate between those found for species from sandy sediments and those found for typical thiobenthic representatives from euxinic sediments. The effects of sulphide and hypoxia were studied in detail for the different life cycle stages of the copepod Acartia tonsa (Invidia et al., Extended Report, Vol. II, p. 509)
