Ordinations are based on either Bray–Curtis (a, stress=0.0966), which utilizes relative compound abundances, or Jaccard distances (b, stress=0.1143), which utilizes presence/absence information. Landscape, climate and in-lake chemistry variables were fit to the ordination. Grey-shaded circles are DOM compounds, whereas black circles indicate the site. Variables with a significance level of <0.05 (light blue), <0.01 (green) and <0.001 (purple) are shown. DOC, dissolved organic carbon; MAP, mean annual precipitation; MAT, mean annual temperature; TN, total nitrogen; TP, total phosphorus; WRT, water residence time.
