A simple, rapid and reliable reversed-phase high-performance liquid chromatographic method for the determination of tagitinin C, an anti-plasmodial sesquiterpene lactone isolated from the aerial parts of Tithonia diversifolia, has been developed. The assay has been used to quantify tagitinin C in various extracts of the aerial parts of T. diversifolia. [less ▲]

Little attention has been paid until now to the processes controlling the production, dissolution and fate of biogenic calcium carbonate in the oceans. It is however well known that net deposition rates of inorganic carbon to the sediments are comparable to those of organic matter. There remains still large uncertainties in the production and redissolution of biogenic carbonate in the marine system and thus about the role of the carbonate pump in response to anthropogenic CO2 perturbations. The understanding of these processes is also a prerequisite to predict the response of marine organisms to global environmental changes. In the framework of the Belgian global change programme, we have developed a project devoted to the study of the inorganic carbon cycle in the Bay of Biscay where coccolithophorid blooms occur frequently. The study focuses on processes associated with the oceanic production and dissolution of calcium carbonate, by combining field investigations, laboratory experiments and modelling efforts. Remote sensing demonstrates a close relationship between vertical mixing along the continental margin and the development of the phytoplankton bloom. We will present here, results of 14C incorporation experiments used to evaluate the rate of production of organic and inorganic particulate carbon, obtained during a coccolithophorid spring bloom in the investigated area. A tentative mass balance of the carbon fluxes for this area will be presented, confirming the importance that the calcium carbonate pump may play in the oceanic system. [less ▲]

Après l’avènement des Systèmes d’Information Géographique et l’utilisation de plus en plus répandue des images aériennes et satellitaires, le LiDAR constitue une nouvelle avancée dans la quantification et le monitoring des ressources naturelles en général et forestières en particulier. Le LiDAR est une technologie d’acquisition d’information en trois dimensions. Collectées le plus souvent à partir d’un avion, les données LiDAR prennent la forme de nuages de points plus ou moins denses qui décrivent finement les structures tridimensionnelle des zones observées et donc du couvert végétal dans le cas de zones forestières. Même si, à l'heure actuelle, l’acquisition des données reste encore relativement coûteuse et leur traitement apparemment complexe, les perspectives d’utilisation de ces données apparaissent très prometteuses au plan de la gestion forestière.
