| The comparative effect of the uptake of fresh and degraded detritus of halophytic plants, harvested from salt marches of the Mont Saint-Michel Bay (France), on the growth of a juvenile population of the annelid polychaete N. diversicolor (L.) was studied under experimental conditions in summer 1993. Fresh and degraded detritus of Spartina anglica, Halimione portulacoides and Salicornia europeae, as well as the green algae Enteromorpha sp. were distributed separately to homogenous set of juveniles for a 75 d period. The highest growth rate was obtained for worms fed with Enteromorpha sp. Administration of fresh detritus of a given halophyte species to N. diversicolor juveniles always leads to a significantly higher growth rate than did degraded detritus.... |

| Dynamic studies of the Abra alba-Melinna palmata muddy sand community from 1972 to 1982 show that after an initial recolonization until 1976 species richness and density exhibit a steady trend. Three groups of species and five main categories of population abundance evolution are deduced from qualitative and quantitative sampling. Rapid stabilization of abiotic factors occurs after the starting up of the tidal power dam in 1966 and the authors' evolutive scheme reflects both importance of hydrodynamic effects in the dispersion of benthic organisms and demographic strategies of main populations, especially annelids (80-90% of the community). Among the six annelid dominant species, four took part in the recolonization of the biotopa although they are able to... |
