The Brazilian Amazon is one of the world’s largest tropical forests. It supplies more than 80 % of Brazil’s timber production and makes this nation the second largest producer of tropical wood. The forestry sector is of major importance in terms of economic production and employment creation. However, the Brazilian Amazon is also known for its high deforestation rate and for its rather unsustainably managed timber resources, a fact which puts in the balance the long-term future of the forestry sector in the region. Since the mid- 1990s, with strong support from World Wildlife Fund (WWF), the number of tropical forests certified by the Forest Stewardship Council (FSC) has significantly increased. This is especially true for projects sponsored by large scale companies. The number of community- based forest management projects has also increased. Certification of community-based forest enterprises (CFEs) was initially a goal for the sponsors and community members. Certification is viewed as a way to reach alternative timber markets. In Brazil, the state of Acre has the highest concentration of CFEs certified by FSC. Most of them have been implemented with the support of environmental NGOs and public funds. Environmental NGOs strongly defend the advantages of certification for communities; however, in reality, this option is not that advantageous. Despite all the efforts, the number of participants in each project remains low. Why is this occurring? In this paper, we analyze the underlying motives of a few individual’s participation in CFEs certification projects. We aim to present and discuss some factors that shape the success of CFEs and their later certification. The results are based on surveys conducted in two certified CFEs in the state of Acre.

Ce mémoire porte sur le cèdre blanc (Thuja occidentalis) dans les contextes de colonisation et d’exploitation forestière de l’arrière-pays montréalais au XIXe siècle. Il vise, d’une part, à documenter les stratégies d’exploitation locale du cèdre blanc au XIXe siècle et l’évolution du paysage culturel domestique d’un établissement colonial depuis sa concession initiale. D’autre part, ce mémoire cherche à identifier les réseaux d’échanges du cèdre blanc acheminé à Montréal au XIXe siècle pour la construction des bâtiments et des infrastructures portuaires. En raison de la quasi-absence de documents historiques sur le sujet, il devient évident que seule l’application de la dendrochronologie et de la dendroprovenance permet d’atteindre ces objectifs. Nous vous présentons ici l’analyse détaillée de six sites ruraux situés dans les vallées de l’Outaouais et du haut Saint-Laurent. Les analyses dendrochronologiques effectuées permettent d’aborder l’établissement colonial d’une façon originale. La deuxième partie de ce mémoire se consacre aux analyses de dendroprovenance de sept sites montréalais préalablement étudiés par Poudret-Barré (2007) et le Groupe de recherche en dendrochronologie historique (GRDH). Pour ce faire, les sites ruraux discutés précédemment servent de point d’ancrage géographique afin de déterminer l’origine des pièces de cèdre blanc retrouvées à Montréal. L’étude du cèdre blanc et les résultats des analyses de dendrochronologie et de dendroprovenance réalisées dans le cadre de cette étude permettent d’aborder le patrimoine architectural et archéologique sous un angle nouveau. Venant compléter les données historiques disponibles, il ouvre la voie à de nouvelles recherches de ce genre.

Les forêts occidentales sont aujourd’hui de plus en plus prisées pour la pratique d’activités récréatives en milieu naturel. Dès lors, la mise en place d’une gestion intégrée des forêts est plus que jamais indispensable au maintien des conditions nécessaires à la pratique de l’ensemble des activités sur le territoire. Le Québec s’est doté d’une nouvelle législation pour répondre aux nombreux enjeux qui touchent le milieu forestier, notamment en ce qui a trait à l’harmonisation entre les activités récréatives et la production ligneuse. Dans le cadre de cette recherche, nous nous sommes intéressés au concept d’expérience du visiteur comme moyen de faciliter cette harmonisation. Il s’agissait à la fois de caractériser l’expérience de visite des utilisateurs d’un parc régional et de se questionner sur son opérationnalisation dans l’aménagement forestier. Deux méthodes qualitatives complémentaires ont été utilisées : d’une part, l’analyse de récits inscrits dans des livres d’or placés dans différents hébergements et d’autre part, des entrevues ont été conduites auprès de visiteurs rencontrés sur le site. Les résultats révèlent la pertinence de considérer l’expérience du visiteur pour favoriser une utilisation plurielle et harmonieuse du territoire forestier. Son étude permet une compréhension fine des composantes communes et spécifiques des expériences, en fonction des visiteurs. Par ailleurs, l’étude témoigne de la possibilité de mettre en relation des typologies d’expériences recherchées et les modalités d’harmonisation. Enfin, au-delà de l’expérience, le suivi de la perception de la foresterie et des représentations peut également s’avérer pertinent pour les gestionnaires.

The present work comprises studies on the salinity tolerance and respiratory metabolism of a mood-boring sphaeromid, Sphaeroma annandalei, Stabbing and two free living,foulers of the family Cirolanidae, Cirolana fluviatilis Stabbing and C. uilleyi Stabbing. Except for the systematic accounts and general observations by Pillai (1961) and the preliminary studies on the salinity tolerance and respiration of C. fluviatilis by Nagabhushanam and Gopalakrishnamurthy (1965, 1965a) very little is known about these isopods From Indian waters. Studies by John (1968) on the habits, structure, and development of Sphaeroma terebrans and by Cheriyan (1973) on the eoéphysiology of the same are the recent major contributions on this interesting group of animals. 5. annandalei is closely related to S. terebrans and has been reported to occur on timber along with the latter (Pillai, 1951). s. gggandalei is a serious pest attacking wood along the Kerala coast, but detailed works on this species have not been undertaken so Far

Sphaeroma terebrans Bate, one of the most destructive wood-boring isopod crustacean occurring in the Cochin harbour region was taken up for investigations on its habitat, breeding, attack on timber, salinity tolerance and respiration. The respiration of the animal under different stresses was noted using an instrument fabricated in the laboratory. Of the various hydrographic conditions of the Cochin harbour region studied, salinity is found to be the most fluctuating factor and the variations are largely influenced by the seasonal rain fall from one side and the tidal currents on the other.In spite of the great fluctuations in salinity, Sphaeroma terebrans occurs throughout the year in the Cochin harbour region, though their number varies in different months. Exposure tests show that Sphaeroma terebrans can remain for about 20 to 24 hours outside water in a damp atmosphere.
