Les cétacés grands plongeurs, cachalots Physeteridae et Kogiidae, et baleines à bec Zipiidae, sont des espèces marines rares. Leur faible densité, aire de distribution étendue et faible disponibilité en surface génèrent de faibles taux d’observations. Cette particularité constitue un défi pour la modélisation d’habitat de ces espèces, préalable à leur conservation. Les modèles doivent gérer l’abondance de zéros qui limitent leur capacité à inférer des résultats écologiquement cohérents. Cette th...

Cette thèse porte sur la localisation de sources acoustiques sous-marines avec application à une expérience en mer. Nous proposons une nouvelle méthode d'appariement basée sur une métrique appelée distance de Hausdorff (HD) en tant que fonction de coût à minimiser, afin d'effectuer l'inversion de localisation. La localisation 2D, en distance et en profondeur, est réalisée en faisant correspondre les schémas de différence de temps d'arrivée (TDOA) en utilisant un seul hydrophone à la réception et...

Protected Areas (PAs) are one effective means to address biodiversity loss. Unfortunately, the history of PA establishment includes forced removal of people from lands that become parks and restrictions on access and use of lands and waters by local people. Relationships between PA managers, stakeholders, including local people, remain in many instances, difficult. This challenges the ability to create new PAs in Canada, where consent by local residents and other stakeholders is critical for P...

Marine plastic pollution is a pervasive problem and is estimated to only increase over the coming years. The realization of this has made several actors take action, of which one is the Danish Hydraulic Institute. Their simulation software MIKE allows for particle tracking in water environments, making it possible to forecast the movement of marine plastic debris. In addition to this, new advancements in marine plastic cleanup technology arise the following question; where are cleanup systems to...

Au début du 20ème siècle, l'étang de Berre était occupée par de larges prairies sous-marines de Zostera qui ont fortement réduit sous l'impact des pollutions et arrivées massives d'eau douce par le canal EDF. Pollutions et arrivées d'eaux ont beaucoup réduit mais les herbiers ne s'étendent pas vers le large. Cette thèse a donc pour but d'analyser les interactions entre les herbiers sous-marins de l'étang de Berre basé sur l'hypothèse que la dynamique hydro-sédimentaire peut jouer un rôle dans le...

Many viruses, which infect algae, code for small membrane proteins with the characteristics of potassium channels. The peculiarity of these channels is that they have a monomer size of less than 100 amino acids. The structural simplicity and functional robustness of these miniature channels makes viral K+ channels very good model systems for understanding the basic molecular architecture of potassium channels. To learn more about structure/function correlates in these simple channel proteins I t...

Dolabrifera dolabrifera, an anaspidean mollusc (sea hare) collected from Panama's Coiba National Park, was subjected to its first marine chemical ecology study. Its digestive gland contained 5a,8a-epidioxycholest-6-en-3ß-ol. This compound, documented for the first time in D. dolabrifera, demonstrated activity against the parasite responsible for leishmania (Leishmania donovani). An evaluation of its dietary repertoire revealed that D. d...

A better understanding of the exchange processes taking place over the oceans is of great importance since the oceans cover about 70 % of the Earth’s surface. With better knowledge the turbulent fluxes can be more accurate parameterized, which is essential in order to improve the weather- and climate models. In this study, the non-dimensional gradient functions for water vapor (Φq) and carbon dioxide (Φc) in the marine boundary layer have principally been studied. The quality of the instrumentat...

Marine protected areas (MPAs) may be implemented as a means of managing human impacts on the marine environment; however, MPAs commonly have both biological and social goals, which are often addressed through the use of multiple use marine zoning. In British Columbia, 900 km2 of the waters surrounding the southern Gulf Islands are under consideration for a National Marine Conservation Area (NMCA). Should the NMCA be created, a marine zoning plan will be developed for the region. Research has s...
