Full textLa lagune de Havre-aux-Maisons aux Îles-de-la-Madeleine dans le Golfe du Saint-Laurent est un système semi-fermé, avec un temps de renouvellement de l’eau jusqu’à 45 jours. Une activité mytilicole modérée a lieu dans la lagune; les moules (Mytilus edulis L.) sont principalement suspendues sous la surface de l’eau. Les moules dépendent de la matière en suspension pour leur nourriture, incluant les micro-organismes eucaryotes planctoniques (protistes et phytoplancton). La répartition spatiale et temporelle des espèces microbiennes marines eucaryotes est déterminée par les conditions physiques, biologiques et chimiques. L’objectif principal de cette thèse était de caractériser la communauté microbienne eucaryote par des méthodes moléculaires (séquençage à haut-débit), à court et moyen terme. Les échantillons ont été prélevés à partir d’un site unique de Juin à Octobre 2009, et pour deux semaines en Août 2010 dans des zones avec ou sans ferme de moules. Les acides gras de la lagune et ceux assimilés et rejetés par M.edulis ont aussi été examinés en 2009 pour déterminer le lien entre profile lipidique planctonique et celui des moules. Dans l’ensemble la vitesse moyenne de vent avait un effet sur la composition en espèces planctoniques en 2009, il y avait une alternance entre les dinoflagellés et les petites cellules photosynthétiques. Ce changement de communauté a peu d’effet sur la nutrition des moules, qui ont ajusté leurs profils d’acides gras indépendamment de la source de nourriture disponible dans l’échelle de temps de l’étude. En 2010, l’échantillonnage aux deux jours pendant deux semaines, la communauté planctonique était similaire dans et hors la ferme de moules, mais différait à chaque échantillonnage. Au niveau de l’espèce, peu d’entre elles semblaient impacter par la présence des moules, ce qui suggére une forte homogénéisation, verticale et horizontale, de l’eau de la lagune. En date, il s’agit de l’étude la plus exhaustive caractérisant la communauté microbienne eucaryotes concernant sa diversité et sa strucuture dans une lagune des Îles de la Madeleine, où la communauté est sensible aux événements météorologiques extérieurs.
The Havre-aux-Maisons lagoon in the Magdalen Islands in Gulf of St-Lawrence is a semi-enclosed system with water residence time of up to 45 days. Limited myticulture is carried out in the lagune; mostly suspended mussels farming, (Mytilus edulis L.). The mussels depend on suspended material, including planktonic microbial eukaryotes (protists and phytoplankton) for food. The spatial and temporal distribution of marine eukaryotic microbial species is thought to be determined by physical, chemical and biological conditions. The main goal of this thesis was to characterize the microbial eukaryotic community uising molecular methods (high throughput sequencing) over medium and short terms. The samples were collected from a single site from June to October 2009 and for two weeks in August 2010 in areas away from and within a mussel farm. Fatty acids from the lagoon plankton and those assimilated and rejected by M. edulis were also examined in 2009 to determine any links between planktonic and mussel lipid profiles. Overall average wind field had the strongest effect on planktonic species composition and in 2009 there was an alternation between dinoflagellates and small photosynthetic cells. The community had little effect on the nutrition of mussels, which adjusted their fatty acid profiles independent of the source of food available over the time scale investigated. In 2010, when sampling every 2 days for two weeks, the plankton community was similar in both farm and off farm sites, but differed on each sampling occasion. At the level of species, very few species were impacted by the presence of mussels suggesting strong horizontal as well as vertical mixing in the lagoon. This is the most exhaustive study to date on the diversity and community structure of microbial eukaryotics in a Magdalen Island lagoon, where we found that the community was most sensitive to external weather events.

Full textCoastal lagoons are productive ecosystems, which are economically as well as biologically important. Bacteria are largely responsible for key ecosystem functions such as organic matter degradation and nutrient recycling, and studies on their diversity and functional roles are necessary to gain knowledge on the overall ecosystem properties. The main objectif of this thesis was to investigate the temporal and functional diversity of the bacterial communities in the water column and in the sediment of the Havre-aux-Maisons lagoon; a strictly marine coastal system located in the Magdalen Islands in the Gulf of St Lawrence, Canada. In the water column, the attached bacterial community was more diverse than the free-living bacterial community and the two communities were phylogenetically different. The temporal changes in communities were linked to the concentration of particulate organic matter. At the phylum level, the sediment bacterial community structure changed little over time. This community was linked to several biogeochemical cycles, in particular to the sulfur cycle. A stable sediment bacterial community structure was altered by major disturbances such as storms and high concentrations of organic matter. Results from quantitative polymerase chain reaction targeting genes coding for enzymes used in nitrogen and sulfur metabolism indicated the importance of sulfur metabolism and potentially nitrogen-fixation in the sediment. An increase in the organic matter concentration in the form of mussel biodeposits had little influence on transcript concentrations of genes involved in denitrification, nitrogen-fixation and sulfate reduction. However there was evidence of an organic loading threshold at which a change in the diversity of the bacteria involved in denitrification and nitrogen-fixation could occur. Overall this thesis demonstrated that bacterial communities are likely good indicators of the biochemical processes in coastal lagoons and similar studies could be applied to other shallow systems.

Full textThis master’s thesis focuses on the discourses and practices by which the Magdalen Islands fishermen and farmers address the issue of climate change. These Madelinots contend daily with climate-related factors in their activities based upon environment exploitation. Guided by the approaches of environmental history and political ecology, this master’s thesis examines the scope of human actions on the nature, the significations given to nature and their resulting socio-environmental repercussions. Likewise, this study aims to better understand the place of climate change in local discourses about the economic livelihoods of fishermen and farmers, the environmental degradations and the energy future of the archipelago. It also demonstrates the social construction of climate change and discerns its social, political and economic components.

Full textThe subject of this study is the regional implantation of microbreweries located in Bas-Saint-Laurent and Gaspésie-Îles-de-la-Madeleine, two regions of Quebec that are distant from urban centers. The regional implantation that these microbreweries demonstrate is observed from different angles : the local origin of resources used in the making of beer, the quality of terroir assigned to the beer, the local marketing of the products, the social significance of the pub in their community and finally the symbolic regional representations that can be found on beer labels. The analysis is carried out with the concepts of local consumption and terroir. Cheers! -- Keywords : Beer, Craft beer, Local consumption, Terroir, Rural areas, Anthroplogy
