Browse And Herbage Yield Following Clearing In The Alberta Montane Aspen Ecoregion, Edmund S. Telfer Jan 1993

Browse And Herbage Yield Following Clearing In The Alberta Montane Aspen Ecoregion, Edmund S. Telfer

Aspen Bibliography

Small openings were cleared by bulldozing in montane aspen Populus tremuloides forest in southwestern Alberta in 1976. Production of browse, forbs and grasses was measured at the end of the growing season 2 and 7 years later. In the 2nd year production of woody twigs was significantly higher than on uncut controls (87.0 kg/ha compared to 56.0 kg/ha). In the 7th year twig production on cut blocks still exceeded that on the control blocks (53.9 kg/ha compared to 35.5 g/ha). Leaf production was also significantly higher on the treated blocks during both years. Forb production and species composition was not …


Behavioral And Thermoregulatory Responses Of Moose To High Ambient Temperatures And Insect Harassment In Aspen-Dominated Forests, Lyle A. Renecker, Robert J. Hudson Jan 1990

Behavioral And Thermoregulatory Responses Of Moose To High Ambient Temperatures And Insect Harassment In Aspen-Dominated Forests, Lyle A. Renecker, Robert J. Hudson

Aspen Bibliography

Heart rate and insect annoyance were studied in hand-reared adult moose (Alces alces) cows released into a 65-ha enclosure in April, May, July, and October. Radiant heat load exerted the greatest influence on heart rates of bedded moose in all months. Wind and insects had lesser, but significant effect during April and May, respectively. Respiratory rate was related to ambient temperature showing a dramatic increase about 14℃.
