    Description: L'etude d'une population naturelle de l'algue rouge Cystoclonium purpureum a montre que les thalles debutent leur croissonce au printemps pour atteindre leur developpement maximum ent ete. En automne, les algues commencent a disparaitre progressivement. En effet, le poids maximum des thalles est atteint en Juillet (No. 40g). Pendant la meme periode, la longueur des algues atteint son maximum (25,3 cm). Quand au diametre de la fronde, son evolution au cours du temps n'est pas claire. La biomass de Cystoclonium atteint egalement son apogee en Juillet (environ 35 g de MS/m2)
    Description: Study of Cystoclonium purpureum showed that thalli begin to grow in spring and reach highest developement in summer. In autumn, these algae disappear gradually. In fact, the maximum weight is obtained in July (No.40g). In the same period, algae length reach its maximum value, too (25,3cm). While frond diameter evolution isn't clear. Biomass of Cystoclonium reach its highest value in July, too (about 35g DM/m super(2))

    Description: Dans ce travail, realise a l'ecloserie de l'INSTOP a Ghar El Melh, on se propose d'exposer les resultats des cultures du phytoplancton dans une salle climatisee en petits volumes. Par opposition aux cultures en grandes volumes soumises aux aleas climatiques, cette technique permet la maitrise des parametres physico-chimiques (lumiere, temperature, sels minerauxa) et l'obtention de hautes densites algales dans un laps de temps assez court. (DBO)
    Description: In this work, conducted in the INSTOP hatchery at Ghar El Melh, the results are given of the culture of small volumes of phytoplankton in an air-conditioned room. As opposed to culture of large volumes, subject to climatic variations, this technique allows the control of physico-chemical parameters (light, temperature, mineral salts) and the production of high algal densities in a short lapse of time.

    Description: L'etude de la viabilite des spores de l'algue rouge Gracilaria verrucosa a montre que le taux de survie diminue de 100% a 8% pour les tetraspores et a 4% pour les carpospores apres trois semaines de culture.

    Description: L'etude de l'influence de la temperature et de la lumiere sur la croissance des tetraspores Gracilaria verrucosa a montre que l'intensite lumineuse optimale est comprise entre 85 et 110 Kappa E/m super(2)/s a 20 degree C et entre 80 et 100 Kappa E/ m super(2)/s a 25 degree C
    Description: Study of temperature and light influence on Gacilaria verrucosa tetraspores growth showed that optimal light intensity is situated between 85 and 110 Kappa E/m super(2)/s at 2 degree C and between 80 and 100 Kappa E/m super(2)/s at 25 degree C.

    Description: Ce travail concerne la repatition spatiale de la macroalgue Gracilaria dans le lac nord de Tunis et la determination des surfaces d'extension correspondant aux differents types de recouvrement de cette espece, durant les moins de Juin-Juillet 1996. Les peuplements de Gracilaria couvrent 265 ha soit 10% seulement de la surface totale du lac et se presentent sous forme de ceintures dans les profondeurs limitrophes (59,5%) ainsi qu'a l'interieur du lac (24%) et au voisinage de la digue centrale (17%).
    Description: This work concerns the red macro seaweed Gracilaria distribution in the Tunis north lake and the surface corresponding to each type recovering during June and July 1996. The Gracilaria covers 265 ha of the lake which correspond to 10% of it's total surface. 59,5% is surrounding the water plan in shallow water, 24% inside and 17% near the central dyke

    Description: Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world’s oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits.
    Description: This work was supported by the Micro B3 project, which is funded from the European Union’s Seventh Framework Programme (FP7; Joint Call OCEAN.2011‐2: Marine microbial diversity – new insights into marine ecosystems functioning and its biotechnological potential) under the grant agreement no 287589.
