Modelling seasonal dynamics of biomasses and nitrogen contents in a seagrass meadow (Zostera noltii Hornem.): application to the Thau lagoon (French Mediterranean coast)

Plus Martin; Chapelle Annie; Menesguen Alain; Deslous-paoli Jean-marc; Auby Isabelle

A numerical deterministic model for a seagrass ecosystem (Zostera noltii meadows) has been developed for the Thau lagoon. It involves both above- and belowground seagrass biomasses, nitrogen quotas and epiphytes. Driving variables are light intensity, wind speed, rain data and water temperature. Thi...

L'utilisation de modèles écologiques dans la lutte contre l'eutrophisation des eaux côtières françaises Using ecological models for fighting against eutrophication of the french coastal waters

Menesguen Alain

Increasing anthropogenic nitrogen and phosphorus loadings in some coastal areas have induced during the last twenty years excessive production of algal material, either phytoplanktonic or macrophytic. This so-called eutrophication phenomenon alters the usual structure of ecosystem and can lead to ma...

L'eutrophisation des eaux marines et saumâtres en Europe, en particulier en France Coastal eutrophication: A review of the situation along the French coasts

Menesguen Alain; Aminot Alain; Belin Catherine; Chapelle Annie; Guillaud Jean-francois; Joanny Michel; Lefebvre Alain

In order to be able to count the cases of coastal eutrophication and to propose methods to monitor as well as to reduce these phenomena, first of all it is necessary to precisely define the word eutrophication itself. Instead of the strict etymological definition, that is to say a progression of...

Isolation and nitrogenase activity of vesicles from Frankia sp. strain EAN1pec.

Tisa, L S; Ensign, J C

Vesicles, specialized cell structures thought to be the site of nitrogen fixation in the actinorhizal bacteria, were isolated from Frankia sp. strain EAN1pec by using French pressure disruption of mycelia followed by differential and isopycnic gradient centrifugation. The isolated vesicles reduced a...

Durum wheat – winter pea intercropping is efficient to improve the use of environmental resources in low input farming in the French southern conditions

Bedoussac, Laurent; Justes, Eric

Nitrogen acquisition and grain protein concentration (GPC) of durum wheat is often a major concern, particularly in low input systems where mineral N is a limited resource. In this present paper we assessed the hypothesis that the performance of durum wheat and winter pea, grown in intercrop (IC) is...

Degradation of pentaerythritol tetranitrate by Enterobacter cloacae PB2.

Bruce, N C; Binks, P R; Nicklin, S; French, C E

A mixed microbial culture capable of metabolizing the explosive pentaerythritol tetranitrate (PETN) was obtained from soil enrichments under aerobic and nitrogen-limiting conditions. A strain of Enterobacter cloacae, designated PB2, was isolated from this culture and was found to use PETN as a sole ...

French, Christopher E.; Bruce, Neil C.; Nicklin, Stephen

Enterobacter cloacae PB2 was originally isolated on the basis of its ability to utilize nitrate esters, such as pentaerythritol tetranitrate (PETN) and glycerol trinitrate, as the sole nitrogen source for growth. The enzyme responsible is an NADPH-dependent reductase designated PETN reductase. E. cl...
