| Harpacticoid copepods (Crustacea) of the Bay of Saint-Brieuc (Western Channel, France) were collected in winter and late spring 1988, at five intertidal and six subtidal sites. 140 species (many new and some rare) were identified, and several diversity indices (Shannon; Fisher et al.; Margalef) were calculated for the different sites: very high values were obtained at some of them, specially in heterogeneous sediment (H' = 5.26). Pearson's correlation coefficients show that diversity was positively correlated with TOM and depth. Correspondence factorial analyses applied to dominant species suggested the existence of an intertidal fine sand assemblage, with a low salinity ''facies'' (sensu Bodin, 1977), and a subtidal heterogeneous muddy sand assemblage,... |

| In the eutrophicated Bay of Saint-Brieuc (western English Channel, France), density and biomass of the multicellular meiofauna were estimated in different intertidal and subtidal biotopes, in winter and late spring. Mean annual biomass varies from 0.5 to 2.3 g.m-2 in the intertidal zone, and from 0.5 to 1.1 g.m-2 in the subtidal zone. Vertical distribution (0-5 versus 5-10 cm) of taxa was considered in the intertidal zone. Results are discussed and compared to literature data: figures were similar to those of comparable biotopes, and there was no detectable effect of eutrophication on meiofauna density and vertical distribution in this area. The ''seasonal stability'' of nematodes was in contrast with a clear annual cycle in harpacticoid copepods. Biomass... |
