Abstract |
Many tropical tree species generate natural decay resistance by producing bioactive metabolites. Among them, Sextonia rubra (Lauraceae) is a widely exploited species for construction in French Guiana. Rubrynolide and rubrenolide, which are secondary metabolites isolated from the stem wood of S. rubra, exhibit potent antifungal and termiticidal activities that result in the exceptional durability of the heartwood. Although the structure and total synthesis of these two biologically active compounds have been well described in literature, little is known about their cellular localization or biosynthesis process in living trees. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) has been well known for its high lateral resolution imaging with a typical beam size of 0.4-2 µm, thus sufficient to image the wood surface at subcellular level.
Wood surfaces of sapwood, transition zone and heartwood from living trees of S. rubra were prepared with ultramicrotome using diamond knife. Each surface was mapped by Bi3+ cluster TOF-SIMS with high lateral resolution (~ 0.4 µm) which was achieved by employing burst alignment primary ion focusing mode with an extraction delay of the secondary ions to improve mass resolution. 3D imaging of a multi-structure wood sample was performed using dual beam depth profiling method, with 25 keV Bi3+ and 10 keV Ar1000+ as analysis and sputter beam, respectively. To examine the effect of life-history traits on the production of bioactive metabolites, the corresponding counterparts from a tree which had suffered stress during growth were investigated as well. |

Abstract |
La mangrove, cette forêt entre terre et mer qui borde les littoraux tropicaux, a longtemps été perçue comme un milieu hostile ou inutile... Elle renvoie aussi à un puissant imaginaire des tropiques qui a inspiré bon nombre de nos plus grands écrivains. Cet écosystème, complexe, abrite les palétuviers capables de vivre les pieds dans l'eau salée, des poissons pouvant respirer hors de l'eau, des crabes ingénieurs et une multitude de bactéries indispensables au recyclage de la matière organique. Aujourd'hui, confrontée à la crevetticulture, aux coupes de bois, à la pollution mais aussi sous l'emprise directe des changements climatiques, cette mangrove, grignotée de toute part, est en danger. Cet ouvrage, rédigé par des chercheurs spécialistes du milieu, nous montre combien sa préservation devient un enjeu écologique mondial tant cet écosystème contribue à l'équilibre des littoraux tropicaux et à ceux de la planète tout entière. Sait-on par exemple que ces forêts maritimes jouent le rôle de puits de carbone en absorbant de grandes quantités de CO2 ? Qu'elles peuvent servir de filtres ou d'éponges face aux pollutions humaines ? Qu'elles constituent un rempart contre les tempêtes ou les tsunamis ? Un livre qui nous invite à poser un regard nouveau sur cette forêt si secrète au cœur des enjeux écologiques tropicaux. |

Abstract |
Le pétrole est le « sang de la terre » et la principale source d’énergie fossile au monde. L’Amazonie équatorienne, terre d’exploitation pétrolière et de colonisation agricole, est un symbole des richesses naturelles de la planète mais aussi un témoin des dommages causés par les activités humaines. Au cœur de cette forêt, de sa biodiversité, de ses ressources et de ses habitants, se tisse le fil d’un voyage scientifique et interdisciplinaire. Ce livre partage des savoirs, des connaissances et des images sur les impacts et risques liés aux activités pétrolières sur l’environnement, la santé, la société et dépeint les conditions de vie en Amazonie. |
