Some Environmental Relationships Of Undergrowth Species In Aspen Communities Of The Intermountain West, W F. Mueggler
Some Environmental Relationships Of Undergrowth Species In Aspen Communities Of The Intermountain West, W F. Mueggler
Aspen Bibliography
This analysis results from an opportunity to explore plant-environmental relationships from data collected for a different purpose. Origin of the data is a study designed to develop an aspen community-type classification for southern Idaho, western Wyoming, Utah, and Nevada which resulted in the publication "Aspen Community Types of the Intermountain Region" GTR INT-250 by W.F. Mueggler (1988).
The Short And Long-Term Effects Of Herbicide Application In Maine Clearcuts On Ant Communities (Hymenoptera: Formicidae), Kerry Frances Lough
The Short And Long-Term Effects Of Herbicide Application In Maine Clearcuts On Ant Communities (Hymenoptera: Formicidae), Kerry Frances Lough
Electronic Theses and Dissertations
The short and long-term effects of glyphosate application on the diversity and abundance of ants in Maine clearcuts was assessed in a two-year study. Glyphosate is applied to release coniferous trees from suppression by competition with deciduous vegetation after a forest is clearcut. Previous research indicates glyphosate has limited immediate and long-term effects on non-target fauna, though specific species can be affected. Limited research on the effects of herbicides on insects indicates some initial decrease in insect populations. Beneficial insects, such as pollinators and predators, positively influence the forest ecosystem, but little research has examined the effects of herbicide application …

Alteration Of Soil Water Content Consequent To Root-Pruning At A Windbreak/Crop Interface In Nebraska, Usa, Qingjiang Hou, James R. Brandle, Kenneth Hubbard, Michele Schoneberger, Carlos Nieto, Charles A. Francis
Alteration Of Soil Water Content Consequent To Root-Pruning At A Windbreak/Crop Interface In Nebraska, Usa, Qingjiang Hou, James R. Brandle, Kenneth Hubbard, Michele Schoneberger, Carlos Nieto, Charles A. Francis

Root-pruning is generally recommended as an appropriate treatment to reduce competition for soil water and/or nutrients and suppression of crop yield in areas adjacent to windbreaks. Several recent studies suggest, however, that factors other than soil water might be causing yield reduction at the interface. For two consecutive years, we evaluated root-pruning effects on soil water at the windbreak/crop interface under both cropped (soybean [Glycine max (L) Merr.] variety ‘Iroquois’, 1997) and non-cropped (1998) conditions in Mead, Nebraska, USA. Volumetric soil water content near the windbreaks was systematically measured at various soil depths, distances from the windbreak, …
Planning For Population Viability On Northern Great Plains National Grasslands, Fred B. Samson, Fritz L. Knopf, Clinton W. Mccarthy, Barry R. Noon, Wayne R. Ostile, Susan M. Rinehart, Scott Larson, Glenn E. Plumb, Gregory L. Schenbeck, Daniel N. Svingen, Timothy W. Byer

Broad-scale information in concert with conservation of individual species must be used to develop conservation priorities and a more integrated ecosystem protection strategy. In 1999 the United States Forest Service initiated an approach for the 1.2 x 106 ha of national grasslands in the Northern Great Plains to fulfill the requirement to maintain viable populations of all native and desirable introduced vertebrate and plant species. The challenge was threefold: 1) develop basic building blocks in the conservation planning approach, 2) apply the approach to national grasslands, and 3) overcome differences that may exist in agency-specific legal and policy requirements. Key …
Effect Of Stand Density On Behavior Of Leaf Area Prediction Models For Eastern White Pine (Pinus Strobus L.) In Maine, Micah D. Pace
Effect Of Stand Density On Behavior Of Leaf Area Prediction Models For Eastern White Pine (Pinus Strobus L.) In Maine, Micah D. Pace
Electronic Theses and Dissertations
There is little debate within the forest science community that leaf area (LA, the surface area of live foliage) or leaf area index (LAI, the total surface area of live foliage per unit of ground area) are important variables, central to enhancing the understanding of forest growth and many forest ecosystem processes. The ability to accurately measure LA1 has become a research priority and has resulted in various methods of estimation for a variety of species and regions. In this study LA estimation models for Pinus strobus L. were developed, tested, and compared across a wide range of densities for …
The Composition Of Cryptophytes (Geophytes) And Other Plants In The Northern Jarrah Forest Of Western Australia: An Analysis Of Logged And Old Growth Forest, Conrad C. Slee
Theses : Honours
Forests are decreasing globally and there are pressing requirements for ecologically sustainable forest management to be implemented at all scales. There has been some criticism of the public managers for forests and the processes used to select reserve systems and silvicultural methods used. Limited research has been conducted on the effects of logging on the plants of the northern Jarrah forest of south western Australia, While fire is a major disturbance event, disturbance during logging operations may remove non-commercial trees, understorey shrubs and change soil conditions. Some plants that regenerate from below ground storage organs such as Cryptophytes (Geophytes) may …
Ten Years Of Change In Beech Stand In North Central Maine Long Affected With Beech Bark Disease, Amanda Farrar
Ten Years Of Change In Beech Stand In North Central Maine Long Affected With Beech Bark Disease, Amanda Farrar
Electronic Theses and Dissertations
In Maine, northern hardwood stands long affected by beech bark disease often still have high numbers of beech trees. This is mostly due to sprouting, and most new stems become severely infected with the disease. Beech that are resistant to the scale insect, Cryptococcus fagisuga Lind., the inciting factor for the disease complex, do exist and often occur in clumps of root sprout origin. In 1989 a long-term study of the effects of commonly used seasonal harvesting regimes on regeneration initiation and survival was established in north central Maine. Treatments included harvest season (winter or summer) and intensity (clearcut or …

If there were a Guiness Book of World Records for trees, quaking aspen would be in it - not once but probably several times.
