Ecotypic Differences In Heat Resistance Of Aspen Leaves, K.M. Peck, S.J. Wallner
Ecotypic Differences In Heat Resistance Of Aspen Leaves, K.M. Peck, S.J. Wallner
Aspen Bibliography
Heat resistance of aspen (Populus tremuloides) leaves was assessed by stressing leaf discs in vitro and measuring electrolyte leakage. Leaves were obtained from trees growing at elevations of 1960, 2195, and 2454 m. Heat tolerance was greatest in leaf samples from trees growing at the lowest site. Trees propagated from these sites and grown at 1520 m for 2 years showed some increase in heat tolerance, but apparent ecotypic differences persisted

Aspen Bibliography
The aspen type in Minnesota occupies about 5.3 million acres, 39 percent of the State's commercial forest land1 Aspen is the State's major commercial species, accounting for 43 percent of all growing-stock removals for products in 1976 (Jakes 1980).

Aspen [Populus Tremuloides] Community Types On The Bridger-Teton National Forest In Western Wyoming [Including A Key With Indicator Species], Andrew P. Youngblood, Walter F. Mueggler
Aspen Bibliography
A classification system is presented for aspen (Populus tremuloides Michx.) dominated forests on the Bridger-Teton National Forest in western Wyoming. Twenty-six aspen community types are defined and described. A diagnostic key that utilizes indicator plant species is provided for field identification of the community types. Vegetation composition, environment, productivity, relationship to surrounding vegetation, and successional status are discussed. Tables are provided for detailed comparisons.

Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala
Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala
Aspen Bibliography
The ability of quaking and bigtooth aspens (Populus tremuloids Michx., P. grandidentata Michx.) to vegetatively regenerate dense stands of root sprouts (suckers) is well documented (Brinkman and Roe 1975). Tens of thousands of suckers per hectare are commonly produced when stands are killed by fire or removed by clearcutting.
Cryptosphaeria Canker And Libertella Decay Of Aspen, Thomas E. Hinds
Cryptosphaeria Canker And Libertella Decay Of Aspen, Thomas E. Hinds
Aspen Bibliography
A recently discovered, widely distributed canker disease of aspen and other poplars throughout the Rocky Mountain region is described. Inoculations with ascospore and conidial isolates of Cryptosphaeria populina show the fungus is capable of causing branch, sprout, and sapling mortality, trunk cankers, and the discoloration and decay of aspen stems previously associated with its imperfect stage, Libertella sp. The greatest average canker elongation 50 mo after September inoculations was 33.5 cm with sapwood decay and discoloration extending to 401 cm. The fungus caused an average weight loss of 13.5% in bark, 27.0% in sapwood, and 19.1% in heartwood blocks. Incidence …

Effects Of Annual Burning On Grassland In The Aspen Parkland Of East-Central Alberta, Howard G. Anderson, Arthur W. Bailey
Effects Of Annual Burning On Grassland In The Aspen Parkland Of East-Central Alberta, Howard G. Anderson, Arthur W. Bailey
Aspen Bibliography
Annual early spring burning has markedly altered the physiognomy and species composition of aspen parkland vegetation of east-central Alberta. Burning was conducted in April for at least 24 years when soil moisture was normally high. The number of herbaceous species per quadrat doubled while a number of woody species declined slightly.
