Changes in the demography and habitat use of three small rodent species (Clethrionomys gapperi, Microtus pennsylvanicus and Peromyscus maniculatus) and snowshoe hares (Lepus americanus) were monitored from July to November 1978. Bi-weekly live-trapping programs in six natural habitat types and in...

Six boreal forest plant species were fumigated in a newly developed environmental growth chamber with SO2 control capability,for up to 40 days at 0.34 ppm SO2. All species showed a gradual decline in CO2 gas exchange which was related to symptom development characteristic of SO2 toxicity. Paper...

Malhotra, S. S., Addison, P. A.
The dominant woody boreal forest plant species were fumigated with 0.34 ppm SO2 under controlled conditions in the laboratory in order to rank their physiological and visual sensitivities to the air pollutant. Deciduous trees and shrubs were much more sensitive than conifers, presumably because...

A study of small mammal populations (small rodents and snowshoe hares), habitat use, small rodent diets, and small mammal damage in natural forest and successional communities was begun in June 1978 and continued until November 1979. Based on population sizes and distributions, four species of...
