F I G U R E 4 Accumulated thermal units (ATU) in two Arctic lakes, Nakyulik (Nak.) and Inuhuktok (Inu.), after inferred spawning events (n = 4), with median hatching dates simulated for lake trout (Salvelinus namaycush) (LT; purple, dashed line, and circles) and Arctic char (Salvelinus alpinus) (AC; blue, triangles) embryos after each event. Predictions were made for both species at all spawning dates to show the potential speciesspecific effect of spawning date on hatch timing. Shading indicates the range of actual predicted median hatching dates corresponding with the presumed spawning of each individual. Fish ID in the legend is ordered by presumed spawning date.
