Quantification of sedimentary pigments with high performance liquid chromatography enabled the examination of changes in phytoplankton community indicators after wildfire in three lakes on the Boreal Plain with 50-year sediment chronologies. The resp

For 12 low-order lakes in the Western Boreal Forest of Canada, lake position in the groundwater flow system and surface hydrologic connection to wetlands accounted for 57% of the variation in the change in postharvest (1997) relative to preharvest (1

Since June 1988, the north basin of eutrophic Amisk Lake has been treated by hypolimnetic oxygenation, while the south basin has served as a reference. In summer 1989, hypolimnetic dissolved oxygen (DO) concentrations were >=>1 mg ·L-1 in the treatm

Year-round injection of pure oxygen into the hypolimnion of one of two basins in Amisk Lake during 1988-1993 changed dissolved oxygen (DO) and nutrient concentrations in both lake basins without eliminating thermal stratification. Changes were greate

Hypolimnetic oxygenation from 1988 to 1991 in the north basin of Amisk Lake increased mean summer (June-August) dissolved oxygen (DO) concentrations in the deep hypolimnion (25 m) from -1 during pretreatment years (1980-1987) to 2.7 mg ·L-1 during t

Effects of hypolimnetic oxygenation on profundal (15-25 m depth) Chironomus spp. in double-basined Amisk Lake were studied from 1988 to 1991. Responses were species specific. Mean densities and biomasses of C. anthracinus at 25 m increased 55- and 10

The effects of Ca(OH) 2 treatment during the open-water season on phytoplankton communities under ice cover were examined for up to three winters (Nov. Apr.) in three eutrophic hardwater lakes in central Alberta. Phytoplankton communities were compar

Six farm ponds (dugouts) and one lake that differ in the history of copper sulfate (CuSO{sub 4}) treatment were selected for studies of effects of sediments resuspension on phytoplankton. All sites are located within 50 km of Peace River, Alberta, an
