A review of epilithic algal biomass, nutrient, and nonfilterable residue data for major Alberta river basins

Description

The objectives of this review were to describe the river course variation of benthic algal biomass, nutrient and nonfilterable residue variables and their interrelationships in Alberta rivers.... More ≫

Description

The objectives of this review were to describe the river course variation of benthic algal biomass, nutrient and nonfilterable residue variables and their interrelationships in Alberta rivers. Trends in these variables were compared between river basins, and the physiographic zones and ecoregions through which these rivers flowed were also documented.
