Biomasse et production primaire du phytoplancton et du microphytobenthos de deux biotopes sableux (Golfe de Fos, France)
Provedor de dados: 5
Autores: Plante-cuny, Marie-reine; Bodoy, Alain.
The primary production (phytoplankton and microphytobenthos) of a coastaL shallow water ecosystem (0.5 m) was investigated in two sandy areas, differing by their wave exposure. The physical and chemical parameters, the functional chlorophyll and pheopigments as well as the primary production were measured monthly, throughout a two-year study. The bivalve Ruditapes decussatus was the dominant species in the sheltered station (RD), whereas Donax trlmcu/us inhabited the other station (DT) which was exposed to the open-sea waves. Microphytic biomasses were determined after extracting chlorophyll a and pheopigments in 90% acetone. by spectrophotometric measurements before and after acidification. Gross hourly primary production was estimated by measuring the...

Note sur les especes mediterraneenes du genre Mustelus (Selachii, Galeoidea, Triakidae).
Provedor de dados: 5
Autores: Quignard, Jean-pierre; Capape, C.
A redescription of the genus Mustelus was undertaken in order to resolve the taxonomic confusion surrounding it. Metric characteristics, number of vertebrae, size and form of the teeth, colour, biology and geographical distribution are considered in description of the species M. mustelus (Linnaeus, 1758), Mustelus asterias Cloquet 1821, and M. mediterraneus new species, the several synonyms for each of which are listed. General remarks on each are made, and a final dichotomous key for identification is presented.
