It is based on Dr Barica’s past work on prairie lakes (Freshwater Institute, Winnipeg) conducted prior to his appointment to NWRI, Burlington. It analyzes controlling factors in formation of ionic composition and phytoplankton biomass of the prairie lakes (surface deposits and soils, erosion, topography, lake morphometry, groundwater composition, etc.) and concludes that it is the semi-arid climate and groundwater flow which explain the extreme variability in lakes salinity and production. However, the ecological instability of the lakes (algal collapses and resulting anoxia) is triggered by meteorological factors. The winter anoxia (winterkill) is the result of continental climate and governed by lake morphometry"--Management perspective. |
