Última In Situ Behavioral Response of Common Loons Associated with Elevated Mercury (Hg) Exposure Ecology and Society Nocera, Joseph J; Acadia University; 023758n@acadiau.ca; Taylor, Philip D; Acadia University; ptaylor@resalliance.org. Common Loons (Gavia immer) in Nova Scotia, Canada have the highest blood mercury (Hg) concentrations of any loon population in North America. Previous studies have shown that exposure to varying levels of Hg in prey is associated with changes in pre-nesting adult behavior. We report here the first association of sublethal blood Hg contamination with changes in behavior of Common Loon young. As Hg levels in their blood rise, the amount of time that chicks spend brooding (by back-riding) decreases (P = 0.004) and time spent preening increases (P = 0.003). The sum increase in energy expenditure is not being compensated for with expected increases in feeding rates or begging. We suggest that such altered time-activity budgets may disrupt the energetic balance...

Ano: 1998 Combining Science and Traditional Ecological Knowledge: Monitoring Populations for Co-Management Ecology and Society Moller, Henrik; University of Otago; henrik.moller@stonebow.otago.ac.nz; Berkes, Fikret; University of Manitoba; berkes@cc.umanitoba.ca; Lyver, Philip O'Brian; University of Otago; LyverP@landcareresearch.co.nz; Kislalioglu, Mina; University of Manitoba; mberkes@mts.net. Using a combination of traditional ecological knowledge and science to monitor populations can greatly assist co-management for sustainable customary wildlife harvests by indigenous peoples. Case studies from Canada and New Zealand emphasize that, although traditional monitoring methods may often be imprecise and qualitative, they are nevertheless valuable because they are based on observations over long time periods, incorporate large sample sizes, are inexpensive, invite the participation of harvesters as researchers, and sometimes incorporate subtle multivariate cross checks for environmental change. A few simple rules suggested by traditional knowledge may produce good management outcomes consistent with fuzzy logic thinking. Science can sometimes...

Ano: 2004 Anishinaabe Adaptation to Environmental Change in Northwestern Ontario: a Case Study in Knowledge Coproduction for Nontimber Forest Products Ecology and Society Davidson-Hunt, Iain J; Natural Resources Institute, University of Manitoba; Iain.Davidson-Hunt@umanitoba.ca; Pengelly, Ryan D.; HTFC Planning & Design; rpengelly@htfc.mb.ca; Sylvester, Olivia; Natural Resources Institute, University of Manitoba; livsylvester@gmail.com. Interaction, negotiation, and sharing knowledge are at the heart of indigenous response to global environmental change. We consider Anishinaabe efforts to devise new institutional arrangements in response to the process of colonialism and changing global markets. Our findings are based on collaborative research undertaken with Anishinaabe colleagues from Pikangikum First Nation, northwestern Ontario. We worked with elders to understand their knowledge, preferences, and opinions regarding appropriate institutional arrangements for the co-production of knowledge required to develop nontimber forest products. We began our research by asking about the values, institutions, and conditions that guide plant harvesting, and then the conditions necessary to...

Ano: 2013 Predator-Resembling Aversive Conditioning for Managing Habituated Wildlife Ecology and Society St. Clair, Colleen Cassady; University of Alberta; cstclair@ualberta.ca; Hurd, Thomas Eric; Banff National Park; tom.hurd@pc.gc.ca. Wildlife habituation near urban centers can disrupt natural ecological processes, destroy habitat, and threaten public safety. Consequently, management of habituated animals is typically invasive and often includes translocation of these animals to remote areas and sometimes even their destruction. Techniques to prevent or reverse habituation and other forms of in situ management are necessary to balance ecological and social requirements, but they have received very little experimental attention to date. This study compared the efficacy of two aversive conditioning treatments that used either humans or dogs to create sequences resembling chases by predators, which, along with a control category, were repeatedly and individually applied to 24 moderately...

Ano: 2005 Aboriginal Peoples and Forest Certification: a Review of the Canadian Situation Ecology and Society Tikina, Anna V.; Faculty of Forestry, University of British Columbia; tikina@interchange.ubc.ca; Innes, John L.; Faculty of Forestry, University of British Columbia; john.innes@ubc.ca; Trosper, Ronald L.; Faculty of Forestry, University of British Columbia; ronald.trosper@ubc.ca; Larson, Bruce C.; Faculty of Forestry, University of British Columbia; bruce.larson@ubc.ca. We assess how different certification standards address Aboriginal issues in Canada, augmenting current legislation related to Aboriginal issues. The benefits from forest certification and the obstacles to its adoption by the Aboriginal community are also reviewed. We conclude that it would take significant effort, time, and resources to achieve widespread Aboriginal adoption of forest certification.

Ano: 2010 Impacts on Canadian Competitiveness of International Climate Change Mitigation Ecology and Society Holling, Christopher; DRI-WEFA; chris.holling@dri-wefa.com; Somerville, Robin; Standard & Poors DRI; rsomervi@dri.mcgraw-hill.com. This article summarizes and provides additional perspective on a study that contributes to the growing body of analyses of the costs of limiting greenhouse gas emissions. The study estimates the economic costs to Canada of six planning scenarios. Four of these scenarios involve the use of tradable emission permits and two involved a carbon tax. In each case, the mechanism's target is to stabilize greenhouse gas emissions at some percentage of 1990 levels (100% or 90%) by either 2010 or 2015. Policies that impose greater constraints on carbon dioxide emissions lead to higher economic costs in terms of foregone output. These costs, however, vary for the same objective, depending on the mechanism chosen and the economic assumptions made. In one typical...

Ano: 2007 Moving Toward Spatial Solutions in Marine Conservation with Indigenous Communities Ecology and Society Ban, Natalie C; Project Seahorse; University of British Columbia Fisheries Centre; n.ban@fisheries.ubc.ca; Vincent, Amanda C.J.; Project Seahorse; University of British Columbia Fisheries Centre; a.vincent@fisheries.ubc.ca. Community and resource user support has often been declared as essential to achieving globally agreed targets for marine protection. Given that indigenous people in Canada have resource use rights, we engaged two indigenous communities in British Columbia for their views on marine planning and protected areas. We developed a three-phased approach for executing our research: building research partnerships, carrying out individual interviews, and holding community discussion sessions. Participants expressed a common goal of recovering depleted species and ensuring the sustainability of indigenous fishing. We found strong support for spatial protection measures, and significant overlaps amongst participants in the areas suggested for protection. The most...

Ano: 2008 Rediscovering Rites of Passage: Education, Transformation, and the Transition to Sustainability Ecology and Society Lertzman, David Adam; University of Calgary; lertzman@ucalgary.ca. This paper focuses on rites of passage as a model for wilderness programs. It draws on my experience in the field, particularly with Native youth in a community-based program called "Rediscovery." The Rediscovery program is discussed, along with concepts of traditional indigenous knowledge and education. Foundational concepts of rites of passage are described in terms of their relevance to youth, outdoor education, and the Rediscovery program in particular. Using Rediscovery as a model, rites of passage are put forward as an educational process for youth from various cultural backgrounds. In this context, the purpose of education is to cultivate self-knowledge and to foster core personal development: the making of whole human beings. The paper closes with...

Ano: 2002 L'evolution des conditions physiologiques de Crassostrea rhizophorae en fonction des niveaux de bioaccumulation et du gradient de pollution ArchiMer Pellerin, M. Informations gathered in the mangrove of the Fort-De-France bay of Martinique (F.W.I.) showed a decreased physiological condition of Crassostrea rhizophorae in the south part of the bay explained by the presence of zinc and by physico-chemical parameters modified in the wet season, such as decreased salinity and decreased levels of nutrients. Bioaccumulation of zinc, lead and cadmium was highly correlated to sediment contamination. Contamination by pesticides and organochlorides was found mainly in oysters from the North part of the bay, characterized by industrial activities and agricultural inputs.

ArchiMer Abgrall, J; Congar, R. This study highlights the economic interrelations among all boats, focusing on two particular cases, on the one hand the French Channel trawler fleet (1978 to 1980), the Quebec trawler fleet (1974 to 1982) on the other. The present results show the extent of changes in vessel profit or loss productivity and the sacrifice owners and crew have to make in order to survive. Results also show the disparities of situations between the different sorts of vessels within a common bioeconomic environment.

Understanding the impact of the environment on temporal trends in the composition and abundance of deep-sea species is essential for forecasting evolution of the community in the context of climate change. The recent development of deep-sea observatories enables multidisciplinary studies of long duration and high temporal resolution. We used a platform at the Ocean Networks Canada NEPTUNE Observatory located in the axis of Barkley Canyon between June 2012 and January 2015 to: (1) characterize the megabenthic community and the environmental conditions in the canyon; (2) investigate temporal patterns in the faunal community; and (3) determine the influence of environmental conditions on the observed patterns. The megafaunal epibenthic community, which...

Ano: 2005 URL: http://www.repository.naturalis.nl/record/209651 Maritime boundaries: Canada vs. United States OMA Cuyvers, L.. When President Harry S. Truman issued a proclamation in 1945 that claimed an exclusive right of the United States to exploit the resources of the seabed and subsoil of its continental shelf, he heralded a new era of national interest in the oceans. The American measure set a policy that was quickly followed by many other states of the world, and as a result, the exclusive jurisdiction of coastal states over the resources in their offshore continental shelves has become one of the generally settled issues of international law of the sea. Less clear, however, are the rules that govern the delineation of the boundaries on the shelf between adjacent and opposite states. Different interpretations of rather ambiguous rules has led to friction between several...

The value of credit guarantee programs has recently been called into question. Credit guarantees are important marketing tools in the world wheat market, both to develop new markets and to compete in existing markets. This study examines the additionality of export credit guarantees. Empirical demand models were developed and estimated using pooled data among importing countries. Models were estimated for each of the principal exporting countries providing export credit guarantees: the United States, Canada and France. Additionality of credit guarantees were also contrasted to the Export Enhancement Program. Positive additionality was found for CCC guarantees, indicating that the GSM programs have resulted in additional exports that would not have...
