Trophic upsurge and the relationship between phytoplankton biomass and productivity in Smallwood Reservoir, Canada
The primary productivities of a natural lake, a new reservoir, and an established reservoir were investigated in western Labrador over two seasons. Productivity of the new reservoir was about twice those of the other two sites. Possible causes for this increased productivity were examined. It was fo...
