The Effects of Forest Management on Birds in the Black Hills of South Dakota
… (Pinus ponderosa), four structural stages of quaking aspen (Populus tremuloides ), and meadow habitats of the Black Hills, South Dakota during 1992 and 1993. I observed 69 species during this study. Dark - eyed Juncos (Junco hyemalis) were common in all habitats except meadows. The …

Synthesis Of 1,3-Dicinnamoyl-2-Acetylglycerol, A Natural Product Derived from Genus Populus that Demonstrates Beaver Repellent Properties
Quaking aspen tree sprouts have been observed to be ignored by foraging beavers in favor of adult trees, despite a nutritional advantage possessed by the sprouts. This unexpected behavior has been found to be related to the presence of a yet undescribed compound present in sprout bark, …

Elk hunting on Turnbull National Wildlife Refuge: impacts on elk movement and aspen regeneration
<p>"In the arid West, quaking aspen (Populus tremuloides) cover less than 10% of the forest landscape, yet support a disproportionate diversity of native plants and animals. When elk (Cervus elaphus) become overabundant, browsing prevents aspen regeneration, reduces survival, and consequently …

Browse Availability, Bite Size, and Effects of Stand Age on Species Composition and Browse Density for Moose in Northeastern Minnesota
… free-ranging moose. Paper birch, willow, and quaking aspen were common in young stands while hazel, mountain maple, and balsam fir (winter) or juneberry (summer) were common in older stands. Browse density also changed with stand age, but the changes in species composition and browse density …

Forest recovery trends following an unprecedented mountain pine beetle outbreak in the southern Rocky Mountains
… seedlings (PICO/PICO.seeds), and lodgepole pine/quaking aspen (PICO/POTR). The six variables with the highest relative importance in predicting forest type were (in order) overstory basal area mortality, precipitation as snow, maximum July temperature, pre-outbreak basal area, pre-outbreak stand …

Effects of predator urine on deterring ungulate browsing of aspen on the Turnbull National Wildlife Refuge
<p>"In the Pacific Northwest, quaking aspen (Populus tremuloides) support large amounts of biodiversity and are considered second only to riparian zones. Due to aspen's ecological importance and recent decline on Turnbull National Wildlife Refuge (TNWR), increasing aspen regeneration is of high …

Ecology of White-Tailed Deer in South Dakota: Growth, Survival, and Winter Nutrition
… evaluated. Ponderosa pine (Pinus ponderosa) and quaking aspen (Populus tremuloides) were the predominant tree species present. Overstory canopy cover at bed sites was less than 34%. Litter averaged 22.2% (+ 1.07) of understory cover at fawn bed sites, with slash averaging 9.1% (+ 0.52), grasses …
