PR (Wolf 2020): 074 - Traditional Knowledge on Caribou Ecology: Vegetation → Caribou → Wolf Food Chain.

This study is a part of a study on contaminants in a northern terrestrial environment. It is well recognized that a wealth of traditional knowledge (TK) exist about the ecology of caribou, and that TK may illuminate the contaminants’ study. On the other hand, a lot of TK has never been documented yet. The goal of the contaminants study was to investigate if fluorinated hydrocarbons (Perfluorocarboxylic acids [PFCAs] and Perfluorosulfonates [PFSAs]) bio-magnify in the terrestrial food system.

Key words: traditional knowledge, contaminants, food chain, caribou ecology, porcupine caribou herd, Gwich’in, barrenground caribou, wolves
