| Summary: | The Arctic is warming at an unprecedented rate, with implications for the marine ecosystem and species that are important for the tradition, culture, and livelihoods of Indigenous people. Inuit in the western Canadian Arctic have identified a need to better understand the impacts of a changing climate on coastal marine species important for subsistence. Greenland cod, ogac, (Gadus ogac) are found in the coastal marine ecosystem and are reportedly experiencing changes in population dynamics in recent years. In this thesis, I present findings from Inuit and scientific knowledge of Greenland cod as a means of linking knowledge systems to advance our understanding of this species and discuss the implications for Inuit livelihoods under a changing environment. The objectives of this research were to: (1) investigate the adaptation potential of Greenland cod, (2) document Inuit knowledge of this species, and (3) examine the cumulative findings of Greenland cod research and discuss the potential impacts of shifting marine resources on livelihoods in the Inuvialuit Settlement Region. I measured individual specialization-generalization of morphological and habitat-trophic traits from Greenland cod collected along the marine coast near Ulukhaktok, Northwest Territories, NT, in the western Canadian Arctic. I then used this information to elicit discussion on their morphology, feeding, and movement behaviour with key knowledge holders in Ulukhaktok. Scientific findings from this project suggest that Greenland cod are overall generalists but display a range in feeding behaviours for two identified morphotypes. These findings highlight the importance of maintaining trait variation to conserve biodiversity while promoting population resilience in wild fish populations. Inuit knowledge holders were able to build a rationale for some of the phenomena observed and identify early signs of ecosystem change. Linking Inuit and scientific knowledge was a two-way process in which the knowledge systems built off one another to inform ... |
