Arctic Char (Salvelinus alpinus (L.)) have been, and remain, an important

subsistence resource for the Inuvialuit, the Inuit of the western Canadian Arctic. The effects

of climate variability and change (CVC) in this region have been noticeably increasing over

the past three decades. There are concerns as to how CVC will affect Arctic Char and the

Inuvialuit who rely on this resource as they will have to adapt to changes in the fishery.

Community-based monitoring, is an important tool for managing Arctic Char. Therefore,

my dissertation focused on the central question of: Which community-based monitoring

factors and parameters would provide the information needed by local resources

users and decision-makers to make informed choices for managing Arctic Char

populations in light of CVC?

This question is investigated through an exploratory research approach and a mixed

method research design, using both scientific and social science methods, and quantitative

(scientific ecological knowledge and observation) and qualitative (Inuvialuit knowledge

and observation) information. It is formatted as three journal manuscripts, an introduction,

and an integrative discussion. The first manuscript examines potential habitat parameters

for monitoring landlocked Arctic Char condition in three lakes on Banks Island in the

Inuvialuit Settlement Region. The second manuscript examines potential local

environmental parameters for monitoring landlocked Arctic Char growth in the same three

lakes. The third manuscript investigates aspects of Arctic Char community-based

monitoring programs (CBMP) in the Canadian North that have led to the sustained

collection of useful data for management of the resource.

This dissertation makes contributions to the field of research by demonstrating the

utility of a mixed methods approach. The results demonstrate similarities and differences

in char growth and condition within and among Capron, Kuptan and Middle lakes on Banks

Island. This supports both lake-specific and regional climate-driven changes, meaning both

lake habitat and local environmental monitoring parameters should be used in char CBMP.

The investigation of char CBMP across northern Canada demonstrates that an adaptive

monitoring approach is important for subsistence fisheries, as changing lifestyles and

environmental changes impacting a fishery can have direct effects on the successful

operation of char CBMP.

Although the concept of environmental sustainability has become increasingly popular, the literature offers little practical guidance to direct priorities or actions to support environmental sustainability in northern Indigenous communities. A case study in Hopedale, Nunatsiavut, and a systematic literature review was undertaken to understand: 1) what aspects of the local environment are of value to a northern Indigenous community; and 2) what does existing literature identify as key elements of a community-based approach to monitor valued aspects of the environment in a northern Indigenous context. Hopedale residents spoke to the importance of going off on the land and identified a number of categories of places in their local environment of importance to them, including: 1) valued areas for human-use, 2) areas to protect, 3) areas of environmental concern, and 4) areas to monitor. The systematic literature review highlighted trends on community-based monitoring (CBM) publications, and identified key 13 elements of CBM approaches that are pertinent to northern Indigenous communities. Insights from this study will inform environmental planning and management in the case community of Hopedale, as well as offer guidance to enhance current and future CBM activities in the North and elsewhere.

Socio-ecological systems are inherently complex and marine mammals are fundamentally challenging to study. In the Arctic, marine mammals occupy a central ecological role, as nutrient cyclers and as a source of food and culture for Indigenous peoples. Inuit have developed a rich knowledge system, which has not been fully actualized in application in most Arctic research. Considering the need for the best available information in marine mammal ecology, the research question guiding this dissertation was: How can multiple methods and approaches be used to more effectively gather, understand, and represent Inuit Knowledge for an improved understanding of marine mammal ecology?

The dissertation investigates this question using a case study of beluga in Nunavik (Arctic Quebec) drawing on the expertise of hunters and Elders to better understand complex questions in marine mammal ecology. The thesis uses a transdisciplinary approach to address the dissertation objective and is comprised of a general introduction, followed by four chapters formatted as journal manuscripts, and closes with an integrated discussion and conclusion. The first manuscript examines the contributions of Traditional Ecological Knowledge (TEK) of beluga to marine mammal literature. The second manuscript uses a sub-set of data gathered through participant mapping to apply a mapping method to explore how the spatial aspects of TEK could be better documented, analyzed, and represented. The third and fourth papers are based on the knowledge shared by hunters and Elders. The third explores the questions 'why do beluga migrate?' and 'what factors influence beluga movement?'. The fourth investigates aspects of beluga foraging ecology.

This dissertation makes methodological contributions through the application of kernel density estimators to participant maps as a method for transforming multiple mapped narratives into a quantitative database. The understandings shared by hunters and Elders make significant ecological contributions, particularly to foraging (e.g. diet composition and seasonal energy intake), and movement ecology (e.g. potential drivers of migration). Broadly these findings contribute to our collective understanding of beluga ecology and have implications for wildlife management.
