Full textLes canyons et chenaux sous-marins sont formés par des courants de densité subaquatiques et sont les principaux conduits par lesquels les sédiments continentaux atteignent les milieux marins profonds. Plusieurs canyons et chenaux sous-marins incisent les marges de l’estuaire et du golfe du Saint-Laurent jusqu’à une profondeur de ≥ 300 m. Des données hydroacoustiques et sédimentologiques récemment acquises ont permis d’analyser en détail la morphologie et les processus sédimentaires tardi-quaternaires qui ont modifié l’architecture de ces systèmes turbiditiques. Quatre types de systèmes turbiditiques ont été identifiés en fonction de leur source respective de sédiments. Un premier type de système, alimenté par la dérive littorale, a été cartographié dans les secteurs de Sept-Îles, Les Escoumins et Tadoussac. La formation et l’évolution de ces trois systèmes semblent être étroitement liées à un apport sédimentaire provenant de l’érosion des rives avoisinantes. Vers la mi-Holocène, alors que la charge sédimentaire provenant des rivières a drastiquement diminué, l’érosion des fronts deltaïques a vraisemblablement contribué à alimenter ces systèmes turbiditiques. L’activité gravitaire est aujourd’hui dominée par des mouvements de masse qui permettent le transfert sédimentaire vers le niveau de base. Un second type de canyon a été découvert dans le secteur de Pointe-des-Monts. Bien qu’il ne reçoive pas d’apport sédimentaire, ce dernier est le seul où des formes en croissant, probablement associées à des courants supercritiques, ont migré récemment. Leur activité holocène peut être expliquée par des mouvements de masse épisodiques et des courants quasi-continus d’origine hydrodynamique se déplaçant sur le plancher marin. Des données sédimentologiques suggèrent que ces courants d’origine hydrodynamique seraient responsables de la formation des canyons. Deux autres types de chenaux et canyons ont été identifiés dans l’estuaire, soit des systèmes reliés aux rivières et aux glaciers. Ces deux types de systèmes ont été actifs majoritairement au début de l’Holocène, alors que la charge sédimentaire transportée vers l’estuaire était plus importante, permettant la génération de courants hyperpycnaux. Ainsi, cette recherche a permis de démontrer la variabilité morphologique des canyons et chenaux de l’estuaire et du golfe du Saint-Laurent ainsi que les différentes phases d’activité et types de processus gravitaires qui ont mené à la formation de systèmes turbiditiques dans un contexte tectonique et climatique similaire.
Submarine canyons and channels are formed by subaqueous sediment density flows and are the main conduits through which continental sediments reach deeper sedimentary basins. Numerous submarine canyons and channels incise the margins of the Estuary and Gulf of St. Lawrence, to a depth of ≥ 300 m. Multibeam bathymetry, acoustic backscatter, seismic reflection and sedimentological analysis have allowed examining in great detail the morphology and the late-Quaternary sedimentary processes within these systems. Four types of submarine fans were identified based on their respective source of sediment. A submarine fan located in ≤ 60 m deep in the Sept-Îles sector has illlustrated the role of longshore drift on the formation and evolution of such systems. Longshore drift, through submarine transverse bars and coastal sand bars, forced the formation of a submarine fan near 5 ka BP. Its activity is now dominated by the passage of low density/intensity flows forming sandwaves on the edge of the coastal shelf and high energy flows (probably slope failures) that allow the accumulation of sediment on the deeper submarine fan. Two other systems fed by longshore drift were identified in the Tadoussac and Les Escoumins sectors, where similar recent episodic activity has been described. A second type of canyon system was discovered in the Pointe-des-Monts sector. These canyons are sediment-starved and yet, they are the only systems in which crescentic bedforms recently migrated upslope. Their short- and long-term activity can be explained by slope failures and quasi-continuous hydrodynamic processes along the seafloor. Sedimentological data suggest that quasi-continuous flows of hydrodynamic origin are responsible for the formation of the canyons. Two other types of channels and canyons were identified in the St. Lawrence: systems fed by rivers and glaciers. Both types of systems were active mainly in the early-Holocene, when sediment supply to the St. Lawrence was greater. When sediment supply drastically diminished during mid-Holocene, erosion of deltaic fronts likely led to an increase in longshore-drift transport and the formation and/or continuated activity of the Sept-Îles and Les Escoumins systems.

Full textL'identification des stocks et la quantification de leur contribution relative au recrutement sont des objectifs majeurs pour améliorer la gestion et la conservation des espèces marines exploitées. Le séquençage de nouvelle génération permet d’analyser des milliers de marqueurs génomiques et d’apporter la résolution nécessaire pour répondre à ces questions chez les espèces marines qui sont faiblement différenciées. Le Flétan du Groenland (Reinhardtius hippoglossoides) est un poisson plat largement exploité, particulièrement dans le golfe du St-Laurent, au Canada. On y retrouve 2 nourriceries connues, dont la contribution des juvéniles au renouvellement des différents stocks adultes reste inconnue à ce jour. Les buts de ce projet sont de i) déterminer la structure des populations de flétan du Groenland du Saint-Laurent et ii) d’estimer la contribution des différents stocks reproducteurs identifiés aux différentes nourriceries. Pour ce faire, nous avons échantillonné 100 juvéniles par nourricerie et 50 adultes de sites s’étendant du fjord du Saguenay jusqu’au large de Terre-Neuve, avec quelques sites échantillonnés sur 2 années consécutives pour évaluer la stabilité temporelle de cette contribution. Nos résultats montrent qu’après avoir retiré les marqueurs liés au sexe, la région de l’Estuaire/Golfe du Saint-Laurent forme une population distincte de l’Atlantique près de Terre-Neuve (Fst = 0.00146, p-value = 0.001). Les analyses d’assignation populationnelle montrent que le recrutement dépend largement du stock du Saint-Laurent. Par ailleurs, on retrouve une contribution variable du stock de Terre-Neuve, variant de 1% pour la première année à 33% pour la deuxième, ce qui suggère un transport interannuel de larves variable selon la force des courants profonds. Cette étude sert de modèle pour l’identification des stocks pour les ressources halieutiques, dans un contexte où le milieu marin offre peu de barrières à la dispersion, en plus de démontrer l’importance des marqueurs liés au sexe et des répliques temporelles en génomique des populations.
The identification of stocks and quantifying their relative contribution to recruitment are major objectives toward improving the management and conservation of marine exploited species. Next-generation sequencing allows to analyze thousands of genomic markers which provide the resolution needed to address these questions in marine species with weakly differentiated populations. Greenland Halibut (Reinhardtius hippoglossoides) is one the most important exploited demersal species throughout the North Atlantic, and in particular in the Gulf of St. Lawrence, Canada. There, two nurseries are known, the St. Lawrence Estuary and the northern Anticosti Island, but their contribution to the renewal of stocks remains unknown. The goals of this study were i) to document the genetic structure and ii) to estimate the contribution of the different identified breeding stocks to nurseries. We sampled 100 juveniles per nursery and 50 adults from seven sites ranging from Saguenay fjord to offshore Newfoundland, with some sites sampled over two consecutive years in order to evaluate the temporal stability of the contribution. Our results show that after removing of sex-linked markers, the Estuary/Gulf of St. Lawrence represent a stock which is genetically distinct from the Atlantic around Newfoundland (Fst = 0.00146, p-value = 0.001). Population assignment showed that recruitment in both nurseries is largely predominantly associated with the St. Lawrence stock. However, we found that the relative contribution of both stocks to the nurseries is temporally variable with 1% contribution of the Newfoundland stock one year but up to 33% for the second year, which may hypothetically be caused by year-to-year variation in larval transport into the Gulf of St. Lawrence. This study serves as a model for the identification of stocks for fisheries resources in a context where few barriers to dispersal occurs, in addition to demonstrating the importance of considering sex-linked markers and temporal replicates in studies of population genomics.

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 textKrill are macrozooplanktonic crustaceans play a key role in the pelagic marine ecosystem. They represent a crucial trophic platform between planktonic primary producers and the upper food-web levels. In a context of environmental changes, understanding the impacts of the natural variability of physical forcing on krill physiology and population dynamics appears essential to better apprehend the dynamics, evolution and management of subarctic marine ecosystems. In the Estuary and Gulf of St. Lawrence (EGSL), krill communities are dominated by two sympatric species, names Meganyctiphanes norvegica and Thysanoessa raschii. The main objective of this research project was to study, through the development of biophysical models, the effects of environmental variability on the distribution, reproduction and growth of these two species. The project allowed us i) to build a species-specific physiological based model (IBM) for adult stage of both krill species and to validate it with available data; ii) to identify spatio-temporally the potential growth and reproduction areas in the EGSL for both species iii) to study the role of the intraspecific variability on T. raschii population dynamics facing the environmental variability. In the first chapter we built a physiological species-specific based model representing realistically the annual adult life cycle for both dominant species at the Rimouski station located in the St. Lawrence River Estuary. We showed that the production dynamics of M. norvegica and T. raschii individuals were strongly linked to the feeding environment. However, both species exhibited well different growth and reproductive trajectories, T. raschii showing a summer production season, while M. norvegica an autumnal production season. The model highlighted how understanding and implementing feeding processes was essential for accurate representation of the growth dynamics of each species. In the second chapter, we coupled the physiological model developed in Chapter 2 with a 3D general circulation model and a biogeochemical model of the NPZD type, in order to study the production dynamics at the EGSL scale. The results showed a strong seasonality of the growth and reproduction potential of both species, closely related to the dynamics of phytoplankton and zooplankton, representing their prey field. Although knowledge was limited in the northeastern Gulf, model results showed the emergence of high production areas in the Estuary, in the Strait of Belle Isle, along the western coast of the Newfoundland and along the North Shore. Our study also highlighted the existence of a larger cyclonic circuit of krill production and transport that runs along the shores of the whole EGSL, from the Avalon Peninsula in the south of Newfoundland to the North Shore of Québec across the Strait of Belle Isle, and back to the Estuary upstream during the production season (April to October). In the third chapter, we are interested in quantifying the relative contribution of interannual environmental variability (2003 and 2006) and inter-individual variability on the production dynamics of T. raschii in the EGSL system. Our results showed that about 15% of the variability of IBM model state variables could be explained by the level of simulated inter-individual variability. Results also showed that inclusion of inter-individual variability did not significantly modify the system's response at the population level in response to the environment: the centrality measures of the state variables obtained between 2003 and 2006 remained similar in the simulations with and without inter-individual variability. However, this has resulted in an expansion of the frequency distributions of the state variables. Moreover, an increase in the positive responses of the state variables during simulations with inter-individual variability also emerged from the results of the model for the year 2003, evoking a resistance of the population to the variability of the environment. These results provide important data to integrate in fully ecosystem-based management plan. They represent a baseline to the study of the inter-annual variability and the understanding of the future production dynamics evolution for the both species.
