Fig. 2: The upper Great Plains and the upper Midwest corn belt show the highest probabilities of exceeding microcystin thresholds.
From: Geographic redistribution of microcystin hotspots in response to climate warming
The exceedance probabilities for each lake are calculated on the basis of the environmental conditions measured at the time of microcystin sampling. a–f, Exceedance probabilities are then averaged across lakes on the HUC6 basin scale (a,c,e) and HUC2 regional scale (b,d,f) for the thresholds 0.3 μg l−1 (a,b), 1 μg l−1 (c,d) and 8 μg l−1 (e,f).
