Modélisation écologique des populations de palourdes roses (Paphia rhomboïdes) et d'amandes de mer (Glycymeris glycymeris) en Manche Ecological modelling of banded carpet shell (Paphia rhomboïdes) and dog cockle (Glycymeris glycymeris) populations in the Channel Sea
Author(s) :
Savina Marie
Description :
Diversity and abundance of the benthic fauna in the Channel Sea have favoured the development of fisheries, particularly those of shellfish (scallop, warty venus, common cockle, dog cockle, banded carpet shell, surf clam...) and also attracted the interest of scientists. Some large scientific progra...

Fluorescent antibody enumeration of Vibrio cholerae in the marine environment.
Description :
From microcosm studies, V. cholerae and related potential human pathogens enter a viable but nonculturable state. Direct viable counts by epifluorescent microscopy consistently remain higher than corresponding plate counts. Thus, the assumption that pathogens "die-off" or "decay" in the marine envir...

Comparaison de methodes directes (microscopiques) et indirectes (par mise en culture) dans l'evaluation d'une pollution bacterienne d'origine fecale. Etude preliminaire Comparison of the direct (microscopy) and indirect (growth on medium) methods for bacterial counting of fecal pollution. Preliminary study.
Description :
Cells of two serotypes of Escherichia coli (O26B6 and 0111B4) were counted using epifluorescence and immunofluorescence microscopy (nonavalent serum) and plate count on specific medium. Values from indirect counts were 10 fold smaller than those from both microscopic counts. In a sample of sea water...

Presence de Microvibrio marinus dans les eaux de l'ocean austral et son pouvoir bactericide Presence of Microvibrio marinus in the Southern Ocean and its bactericidal effect.
Description :
Sea-water from the subantarctic region appears to be strongly bactericidal. When diluted: 1:10,000 it kills E. coli within a few days. Cultures prepared with this water contain numerous microvibrios apparently as a pure strain. Microvibrio- free filtrates of the culture are still able to kill E. col...

The dispersal of nitrogen-fixing Enterobacteriaceae from sewage into the waters and sediments of Morecambe Bay, UK.
Description :
The sediments of Morecambe Bay contain large numbers of salinity-tolerant, nitrogen-fixing Enterobacteriaceae (NFEs) mainly Klebsiella pneumoniae ) which appear to be derived from sewage. Sewage effluents, regardless as to whether they have received primary or secondary treatment, contain huge numbe...

Description :
Microalgal populations along French coasts (English Channel, Bay of Biscay and Mediterranean Sea) have been sampled twice a month since 1987 within the context of the French Phytoplankton and Phycotoxin Monitoring Network (REPHY). This study used these data to characterize the large-scale geographic...

Description :
Eastward currents in the thermocline and subthermocline layers of the tropical Atlantic Ocean are described using observations obtained during two boreal summer cruises covering the whole equatorial basin. The analysis focuses on the eastward evolution of zonal currents in the thermocline and sub-th...

Determination du profil des flores bacteriennes des zones littorales. Application a l'evaluation de l'impact des rejets Profile determination of bacterial flora in coastal waters. Application to the evaluation of impact zone of disposal.
Description :
The principle of this method is to evaluate, by counts exercised upon selective media, the relative importance of the different bacteria families in the flora of the coastal waters. It is important to separate the contaminant species and the commensal species in the marine environment. Ten culture m...

Description :
[1] The equatorial Pacific and Atlantic oceans exhibit remarkable meridional undulations in temperature and chlorophyll fronts visible from space over thousands of kilometers and often referred to as tropical instability waves. Here, we present new observations of an ecosystem ranging through three ...
