Biotic communities in shallow northern lakes are frequently used to assess environmental change, however complex interactions among multiple factors remain understudied. Here, we present analysis of a comprehensive data set that evaluates the influence input waters, catchment characteristics, limnology, and sediment properties on diatom and chironomid assemblages in surface sediments of ~49 shallow mainly thermokarst lakes in Old Crow Flats, Yukon. Multivariate analyses and ANOSIM tests identified that composition of diatom (119 taxa) and chironomid (68 taxa) assemblages differ significantly (p The accepted manuscript in pdf format is listed with the files at the bottom of this page.
