Figure 1From: Loss of trophic complexity in saline prairie lakes as indicated by stable-isotope based community-metricsLocation of the 20 study lakes in the northern Great Plains of Saskatchewan, with sample sites shown as open circles and major cities as open squares. Dashed lines indicate isopleths of total precipitation minus total potential evapotranspiration (cm yr-1) [16]. Solid line denotes grassland transition. All lakes are located within endorheic drainage basins.Back to article page
