Aspen Bibliography
We must be resourceful. Our "natural" resources are becoming scarcer every day, while waste products mushroom in dumps, along roadsides, in the water and air.

The Influence Of Predator Control On Two Adjacent Wintering Deer Herds, Dennis D. Austin, Philip J. Urness, Michael L. Wolfe
Aspen Bibliography
An unknown number of deer are continually killed on summer and winter ranges by predators, and in at least some locations these losses are significant.

Dickey-Lincoln School Lakes Project Environmental Impact Statement : Appendix G: Recreation Resources, Northern Maine Regional Planning Commission, Land Use Consultants, Inc., New England Division, U.S. Army Corps Of Engineers
Dickey-Lincoln School Lakes Project
This report is to evaluate and describe the existing recreational use and resources of the project area and the encompassing study area and to project the future use of those resources both with and without the Dickey-Lincoln School Lakes Project. The primary impact area of the proposed project (project area) includes the St. John River watershed upstream of the proposed damsites to the confluence of Nine-mile Brook. The area is bounded by the watershed divide with the Allagash River on the east and the Canadian Border on the west.
Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil
Visual Detection Of Cryptic Prey By Blue Jays (Cyanocitta Cristata), Alexandra T. Pietrewicz, Alan Kamil
Avian Cognition Papers
Blue jays learned to respond differentially to the presence or absence of Catocala moths in slides. This detection of the moths by the jays was affected by the background upon which the moth was placed and its body orientation, thus providing an objective measure of crypticity. These procedures are useful for the study of visual detection of prey.
Biomass Estimation For Some Shrubs From Northeastern Minnesota, David F. Grigal, Lewis F. Ohmann
Biomass Estimation For Some Shrubs From Northeastern Minnesota, David F. Grigal, Lewis F. Ohmann
Aspen Bibliography
Biomass prediction equations were developed for 23 northeastern Minnesota shrub species. The allometric function was used to predict leaf, current annual woody twig, stem, and total woody biomass (dry grams), using stem diameter class estimated to the nearest 0.25 cm class at 15 cm above ground level as the independent variable.

Aspen Bibliography
The establishment of an experiment designed to study the effect of thinning and fertilization in a 6 year-old trembling aspen stand, provided the opportunity to determine the mass of the standing crop present at the age.

Forest Insect And Disease Management : Aspen Mortality At The Maroon Lake Campground, David W. Johnson, Thomas E. Hinds
Aspen Bibliography
At the request of the White River National Forest, Dave Johnson, Plant Pathologist, FI&DM and Tom Hinds, Plant Pathologist, RMFRES, made an evaluation of aspen mortality in the Maroon Lake Campground, Aspen Ranger District during June 13 to 15, 1977. Previously, Hinds (1976) reported accelerated aspen loss in 17 campgrounds, including Maroon Lake, located throughout Colorado and New Mexico (Fig. 1).

Aspen Bibliography
This is one of the reports developed as part of the Forest-Range Environmental Study (FRES) of the Forest Service, U.S. Department of Agriculture. This report presents descriptive sketches of 34 soil-vegetation units, called ecosystems. These cover all the land area of the 48 contiguous States.
