A graduate assistantship is available to carry out either a Master’s or Ph.D. thesis in the Aquatic Ecology Group of the Université du Québec à Montréal (UQÀM). The projects will be associated to the NSERC-funded Chair in Carbon Biogeochemistry in Boreal Aquatic Systems (CarBBAS). The research projects may focus on a wide range of issues related to C biogeochemistry and greenhouse gas dynamics in northern aquatic ecosystems, including lake and river organic carbon dynamics and processing, green house gas dynamics, and ecosystem metabolism; links between aquatic and terrestrial C biogeochemistry and ecosystem function, and the role of aquatic ecosystems on regional carbon budgets. The projects will likely involve a combination of approaches, including in situ point and continuous gas, chemical and physical measurements, optical, isotopic and chemical characterization of organic matter, a wide range of process measurements, GIS and landscape modeling measurements, and molecular microbial techniques. The research favors an integrative, network scale perspective of inland waters across the boreal biome of Québec, but comparative work in temperate and subarctic systems in Québec and elsewhere will also be carried out. Our students are part of a highly dynamic, diverse and multidisciplinary aquatic group in the Département des sciences biologiques of the UQÀM, with expertise ranging from nutrient and C biogeochemistry, modeling, to microbial, plankton and fish ecology. The UQÀM is a francophone university, but graduate students have a choice of courses and can submit their theses in English. Interested students should send a letter of introduction, academic resume, and the names of two references, to Paul del Giorgio (firstname.lastname@example.org, 514-7957983). E-mail enquiries and applications are welcome.
