Field trial on an already vegetated area on the GCOS tailings pond dike, to determine responses of the already established vegetative cover to different fertility levels, and fate of added fertilizer

Streamflow in all basins influenced by the disturbance of muskeg. Where muskeg is removed and replaced by mineral soils, stream discharge will decrease during spring runoff and stormflow periods

12 to 40.% of streamflow during the late spring, summer and fall months consists of groundwater; the remainder comes from lake and muskeg drainage, as well as direct precipitation on stream channels

Objectives were addressed in a whole lake experiment at the Experimental Lakes Area in northwestern Ontario because of the experimental control that could be effected at the facilities

Members of 261 insect families were found in the study area, of which 220 were collected in this survey. Damage surveys showed great variation in the rates of insect attack on dominant plant species

Representatives of 50 insect families were collected in sweep net samples, and additional families were observed to be present on the Suncor dike. Insect attacks were severe on conifer trees

Biomass of insects collected averaged 0.82 g oven-dry weight m-2, and ranged from 0.28 (Jack Pine forest) to 3.11 (fen) grams. Use of insects as environmental monitors is discussed

Climatological analysis of recent data from the MAPS network of automatic meteorological data acquisition, forestry lookout stations, minisondes, pack surveys, and the Fort McMurray station

This paper reviews moose habitat selection and discusses the environmental factors which affect selection

Wood frog (Rana sylvatica) was the most abundant and widespread species in 20 sites examined. Boreal chorus frogs (Pseudacris triseriata maculata) and Canadian toads (Bufohemiophrys) found at
