Here, we aimed to establish the temporal and spatial extent of spawning based on a novel hatch-date analysis of juveniles. Spawning activity Key words: alosine clupeid; hatch-date analysis; lasted from early May to early July. We found that juveniles captured multiple spawning events downstream during the summer hatched later in the year than those captured further upstream. As a result, younger juveniles were distributed Julian J. Dodson, De´partement de Biologie, 1045 Avenue de la Me´decine, Universite´ Laval, Que´bec, somewhat further downstream.

  • The Case of the Mactaquac Dam, Canada
    The role of ecosystem services in conflicts over potential dam removal – the case of the Mactaquac Dam, Canada By Kate Helen Reilly Department of Bioresource Engineering McGill University, Montreal Submitted April 2018 A thesis submitted to McGill University in partial fulfilment of the requirements of the degree of Doctor of Philosophy ©Kate Reilly, 2018 1 ABSTRACT Dams across North America are coming to the end of their planned lifespans. Changing societal values and needs, safety concerns, and high maintenance costs are causing their removal to be increasingly considered. Both constructing and removing dams significantly change river ecology and hydrology, and therefore also the provision of ecosystem services. Such changes affect stakeholders differently, according to their needs, values and perceptions of ecosystem services. Understanding these differential impacts is important to ensure effective and equitable decision making, and as a basis for understanding and resolving any resulting conflict. The aims of this thesis, therefore, were to identify and analyse the social demand for ecosystem services, and analyse the extent to which social demand for ecosystem services underlies stakeholder conflict and how the concept of ecosystem services can be used for its resolution. A new conceptual framework was developed that linked ecosystem services to stakeholder responses to a decision-making process from a wider range of angles than has been studied to date. The framework focused on social demand for ecosystem services, as opposed to their biophysical provision or economic valuation, as the aspect most directly relevant to stakeholders and the least studied. Frame theory was used to systematically analyse stakeholders’ perceptions of the decision and how differences between them contribute to conflict.

  • NEWS RELEASE Canada's Brightest Youth
    NEWS RELEASE June 20, 2018 Canada’s Brightest Youth Prepare for Transformational Month of Intense Enrichment and Entrepreneurship at SHAD An actor and a top prize winner from the Canada-Wide Science Fair will join about 1,000 students looking to become change makers this summer at the award-winning enrichment and entrepreneurship program SHAD. This year’s SHAD program will take place at a record 16 host university campuses from coast to coast, with students being represented from all 10 provinces and three territories. Grade 10 student Eva Greyeyes who has a supporting role in the movie “Indian Horse,” a film about an Indigenous boy sent to a residential school, will attend SHAD at the University of New Brunswick in Fredericton. “Indian Horse” premiered at the Toronto International Film Festival and has recently been sent to the big screen at cinemas. “It was so important for me to be able to represent a part of Canada’s history that really needs to be told and it’s important for me to be able to tell that story and tell it with other [Indigenous] people,” Greyeyes said. When speaking about the film’s theme of reconciliation, she said “there was no holding back.” “I think the film coming out was a really big success and a really big step forward.” Greyeyes first learned about SHAD from a poster and presentation in her school. “By the end of the talk, I just remember thinking ‘Oh my goodness, I have to do this! This sounds like one of the best opportunities that I could have in Canada.’” During the month, students attend interactive lectures and workshops from top university faculty and innovators in the community.
