Distant side view of the Steamboat Robert Fulton at Snake Cay, Abaco, Bahamas ; The Bryant Slides Collection ; The Bryant Slides Collection, Bahamas Auteur(s) : Unknown ( Photographer ) Résumé : The slides were taken on collecting trips sponsored by the William L. Bryant Foundation, where books, music and art indigenous to the regions were gathered. The are organized by geographical location. Robert Fulton (1765-1815) was an American inventor credited with adapting the steam engine for commercial use in boats. He worked with Robert Livingston to provide steamboat service along the Hudson River. The steamboat pictured went into service in 1909, the year of the Hudson-Fulton Celebration which celebrated Henry Hudson’s exploration of the Hudson River and Robert Fulton’s paddle steamer. Steamboat Robert Fulton belonged to the Hudson River Day Line and made its final voyage on September 13, 1948 traveling along the Hudson River from Albany to New York City. In 1959, the steamboat was brought on land to Snake Cay, Abaco, Bahamas where it later housed the offices and apartments for Owens-Illinois Incorporated, a lumber company. The image shows cars parked next to the steamboat and in the distance are stacks of lumber behind what appears to be metal scaffolding. Slide labeled Robert Fulton Snake Cay Abaco April '65.

New Insights on Wood Dimensional Stability Influenced by Secondary Metabolites: The Case of a Fast-Growing Tropical Species Bagassa guianensis Aubl. Auteur(s) : Bossu, Julie Beauchêne, Jacques Estevez, Yannick Duplais, Christophe Clair, Bruno Auteurs secondaires : Ecologie des forêts de Guyane (ECOFOG) ; Centre de Coopération Internationale en Recherche Agronomique pour le Développement (CIRAD) - Institut National de la Recherche Agronomique (INRA) - Université des Antilles et de la Guyane (UAG) - AgroParisTech - Université de Guyane (UG) - Centre National de la Recherche Scientifique (CNRS) Éditeur(s) : HAL CCSD Public Library of Science Résumé : International audience Challenging evaluation of tropical forest biodiversity requires the reporting of taxonomic diversity but also the systematic characterization of wood properties in order to discover new promising species for timber industry. Among wood properties, the dimensional stability is regarded as a major technological characteristic to validate whether a wood species is adapted to commercial uses. Cell structure and organization are known to influence the drying shrinkage making wood density and microfibrils angle markers of choice to predict wood dimensional stability. On the contrary the role of wood extractive content remains unclear. This work focuses on the fast-growing tropical species Bagassa guianensis and we report herein a correlation between heartwood drying shrinkage and extractive content. Chemical extractions and shrinkage experiments were performed on separate wood twin samples to better evaluate correctly how secondary metabolites influence the wood shrinkage behaviour. Extractive content were qualitatively and quantitatively analysed using HPLC and NMR spectroscopy. We found that B guianensis heartwood has a homogeneous low shrinkage along its radius that could not be explained only by its basic density. In fact the low drying shrinkage is correlated to the high extractive content and a corrected model to improve the prediction of wood dimensional stability is presented. Additionally NMR experiments conducted on sapwood and heartwood extracts demonstrate that secondary metabolites biosynthesis occurs in sapwood thus revealing B. guianensis as a Juglans-Type heartwood formation. This work demonstrates that B. guianensis, a fast-growing species associated with high durability and high dimensional stability, is a good candidate for lumber production and commercial purposes.

Diversité des termites xylophages en Guyane française : Influence de l’attractivité de l’essence de bois, de la saison et du milieu ; Diversity of termites xylophagous in french Guiana. Atractivity influence, with wood species, with saisonality and with environment. Auteur(s) : Martin, Jean-Michel Auteurs secondaires : Antilles-Guyane Dejean, Alain Résumé : Les termites ont un rôle clé dans le fonctionnement de l’écosystème forêt en particulier celui du recyclage de la litière en matière organique. Cependant, quelques espèces de termites sont des xylophages spécialisés dans la dégradation du bois des forêts, mais sont considérés comme des nuisibles dans les zones anthropisées.En France, le problème « termites » lié aux constructions n’a été traité que dans les années 90. La loi n°99-471, votée le 8 juin 1999 définit les modalités de mise en oeuvre d´une politique de lutte dans laquelle sont engagés tous les acteurs: l´Etat, les collectivités locales, les professionnels ainsi que les propriétaires d´immeubles. La Guyane-française est située dans la carte établie par le FCBA des départements de France où l’arrêté est effectif. Toutefois, ce département d’outre-mer reste aujourd’hui avec beaucoup de lacunes en termes de connaissances sur ses termites.On connaît de façon exhaustive le nombre et les différentes espèces de termites xylophages et on sait également quelles sont les principales familles qui sont présentes dans les bâtiments. Mais on ne sait pas dire quelles sont les espèces de termites qui s’intéressent à nos bois d’œuvres.L’objectif de cette étude est d’identifier les genres et espèces de termites qui s’attaquent à trois essences de bois de durabilité faible ou moyenne (Gonfolo, Simarouba et Yayamadou) et de comprendre comment ces attaques se produisent, en contexte forestier, en lien avec des variables du milieu, et l’effet de la saison de mise en contact.Le Yayamadou est une espèce très appétante pour les termites de Guyane, à condition de disposer de tas de bois d’un volume suffisant (> 500cm3), c’est l’espèce qui présente la plus grande diversité de termites actifs. 18 espèces de termites ont été trouvées sur les tas de bois, mais 10 seulement avec une fréquence dépassant le %. Une description détaillée et une clé d’identification sont proposées pour ces espèces.La diversité des termites est plus importante dans les milieux forestiers naturels. Les résultats montrent, qu’Heterotermes tenuis est l’espèce la plus fréquente quel que soit le milieu. Il y a une spécificité attractive de certaines espèces de termites pour telle essence plutôt que telle autre.Enfin, la saisonnalité, correspondant au moment où l’on installe les échantillons de bois en forêt, joue un rôle dans l’apparition de termites sur telle ou telle essence de bois. Il existe dans chaque milieu des espèces qui peuvent potentiellement s’attaquer au bois des habitations The termites have a role key in the functioning of the ecosystem forest in particular the one of the recycling of the litter in organic matter. Nevertheless, some termites species are specialized in the degradation of the wood of the forests, but are considered plagues in humans place.In France, the problem « termites » linked by the buildings was treated only in the 90’s. The law n°99-471, voted by the 8 June 1999 defines the methods of implement of politics to fights in which are engaged all the actors: the government, the local groups, the professionals as well as the owners of buildings. The French Guiana-is in the map established by the FCBA that departments of France where the law is effective. Nevertheless, this “outre-mer” department remains today with a lot of gaps in terms of knowledge on its termites. We know in a manner exhaustive the number and the different types of xylophagous termites and we know too which are the principal families that are present in the buildings. But we don’t know to say which are the types of termites that are very interested in our lumber.The objective of this study is to identify the genera and termites species that attack themselves to three sorts of wood of weak or average durability (Gonfolo, Simarouba et Yayamadou) and to understand how these attacks produce themselves, in forest context, in link with variables of the environment, and the effect of the season of placement in contact.The Yayamadou is a Wood specie that atracts a lot of termites in French Guiana, to condition to have access to pile of wood of a sufficient volume (> 500cm3), it is the type that presents the biggest diversity of active termites. 18 species of termites were found on the wood piles, but 10 only with a frequency surpassing the 80%. A detailed description and an identification key are proposed for these species. The diversity of the termites is more important in the natural forest environments. The results show, that Heterotermes tenure is the type the does more frequent whatever the environment. There is an attractive specificity of some types of termites for such wood species rather than such other.Finally, the seasonality, corresponding the moment when we installs the wood samples in forest, plays a role in the appearance of termites on such or such wood species. There are in every environment of the types that potentially can attack the wood of the buildings. http://www.theses.fr/2012AGUY0571/document | Partager |
