Analysis of zooplankton communities of Nova Scotia lakes with reference to water chemistry
(Dalhousie Printing Centre, 1987-12)Zooplankton collections from Nova Scotian lakes were analysed to determine if relationships existed between plankton distributions and chemical variables associated with acid rain. A total of 27 taxa was identified. The ... -
The effect of lime on the zooplankton population of Sandy Lake, Halifax County, Nova Scotia
(Dalhousie Printing Centre, 1988-05)Liming of Sandy Lake, Nova Scotia, during July and August of 1981 produced an abrupt and transient increase in the pH of the lake and concurrent changes in the zooplankton community. Immediately following liming, the ... -
Experimental Studies of the Effects of Acidity and Associated Water Chemistry on Amphibians
(Dalhousie Printing Centre, 1985-12)Laboratory bioassays with 5 species of Nova Scotian amphibians (Ambystoma maculatum, Hyla crucifer, Rana sylvatica, R. palustris, and Bufo americana) and Xenopus laevis revealed pH 4.0 to 5.0 as the critical range within ... -
Ionic and mass balances in a dilute acidified brown water lake
(1986-07)Soldier Lake (1.98 km<sup>2</sup>) is an undeveloped, oligotrophic, brown water lake near the Halifax International Airport in central Nova Scotia, which has been acidified from leaching of pyritized metalliferous slates ... -
Primary production of two small lakes in Atlantic Canada
(Dalhousie Printing Centre, 1988-05)At Layton’s lake, Nova Scotia, the total annual primary production was estimated to be 182 gC m<sup>-2</sup> y<sup>-1</sup> of which 87 gC m<sup>-2</sup> y<sup>-1</sup> was planktonic production. Macrophyte production ...
