Mercury monitoring data in Stewart Lake, near Kuujjuaq, Nunavik

Foodweb position is ultimately determined by ecological processes (e.g., competition), environmental forcing (e.g., climate-change), that work directly and indirectly to affect mercury (Hg) uptake by fish (Power et al. 2002). Using fish data collected with standardized effort and gear type in Stewart Lake from two discrete periods (1999 vs 2014), between which significant local warming occurred, we examine the effects of climate warming on the fish community (relative abundance) and fish condition to draw inferences about: [1] whether warming has been associated with significant structural ecological change, and, [2] what the consequences of change may be for measured Hg concentrations in the dominant predatory fish species (Lake trout).
