Potential Influence of Climate Change on the Acid-Sensitivity of High-Elevation Lakes in the Georgia Basin, British Columbia

Figure 3

Redundancy analysis biplot for water chemical parameters in study lakes in the Georgia Basin, British Columbia. Black solid lines represent the explanatory variables (elevation, precipitation, air temperature, S deposition = sulphur deposition, % alpine = % alpine land cover, and % forest = % forested land cover) and black solid squares represent the water chemistry variables. (Note: several water chemistry variables were grouped together in the biplot to improve visual presentation: Cu = copper, = nitrate, Sb = antimony, Pb = lead, Co = cobalt, surface water temperature, DOC = dissolved organic carbon, aluminum, manganese, Na⁺ = sodium, silicon, Ca²⁺ = calcium, conductivity, magnesium, acid-neutralizing capacity, strontium, = sulphate, vanadium, barium, alkalinity, pH = pH, field pH, K⁺ = potassium, phosphorus, and uranium.) Open circles represent the study lakes.
