Table S1: Environmental parameters for lake sites included in the diatom dataset, including 2022 (LK) and 2006 (S) sampling.Mean values are shown for 2022 sampling.Site location refers to p = plateau or c = coastal sites, Si = silicate, PO4 -3 = phosphate, TON = total oxidised nitrogen, < indicates measurements were below detection limits.Nutrient variables for 2022 (LK) sites were measured with ICP-AES and 2006 (S) sites were measured using an Alpkem Autoanalyser (Continuous Flow Solution Analyser).Lake ID Easting Northing Site location Temperature (°C) DO (mg L -1 ) Conductivity (µS cm -1 ) pH Si (mg L -1 ) PO4 -3 (mg L -1 ) TON (mg L -1 ) LK1 494110 3959140 p 8.4 11.49 180 7.65 1.067 < 0.010 < 0.060 LK2 492797 3957444 p 8.6 11.88 172 7.28 0.767 < 0.010
