The Effect Of Temperature On Seed Quality And Quantity In Crosses Between European (Populus Tremula) And Hybrid Aspens (P. Tremula X P. Tremuloides), L. Koviuranta, T. Latva-Karjanmaa, P. Pulkkinen
The Effect Of Temperature On Seed Quality And Quantity In Crosses Between European (Populus Tremula) And Hybrid Aspens (P. Tremula X P. Tremuloides), L. Koviuranta, T. Latva-Karjanmaa, P. Pulkkinen
Aspen Bibliography
Hybrid aspen (Populus tremula L. Populus tremuloides Michx.) plantations are expanding in Fennoscandia and the Baltic countries; however, the possible effects of plantations on the native European aspen (P. tremula) and the level of gene flow between European and hybrid aspen have not been investigated. We studied seed quantity and quality in intraspecific and interspecific crosses of the European and hybrid aspens over a two year period. In order to study whether elevated temperatures due to climate change would benefit the species differently, we performed the crosses in different temperatures. In both years, interspecific crosses produced more seeds with higher …
Effects Of Slash Pile Burning After Restoring Conifer- Encroached Aspen, Christa M. Dagley, John-Pascal Berrill, Stephanie Coppeto, Kyle Jacobson
Effects Of Slash Pile Burning After Restoring Conifer- Encroached Aspen, Christa M. Dagley, John-Pascal Berrill, Stephanie Coppeto, Kyle Jacobson
Aspen Bibliography
Removal of conifers encroaching aspen stands has been advocated and is being practiced in the Lake Tahoe Basin (EIP Project #10080: Aspen Community Restoration Projects). In remote and roadless areas, thinning of conifers is generating large volumes of wood and pile burning is currently being implemented to handle this biomass on site. However, the effects of pile burning on aspen are unknown, and there is an urgent need for guidelines to support design of thinning treatment prescriptions; specifically burn pile size and safe distances from live aspen trees of any size to prevent injury.

Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2010, Katherine Mcgraw, Jennie Popp, Wayne Miller
Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2010, Katherine Mcgraw, Jennie Popp, Wayne Miller
Research Reports and Research Bulletins
This report is the seventh in a series of reports examining agriculture’s economic contribution on the Arkansas economy. Utilizing data from the United States Bureau of Economic Analysis (BEA), USDA Economic Research Service (ERS), USDA National Agricultural Statistics Service (NASS), and Minnesota IMPLAN Group, Inc. (MIG), the economic contribution of agriculture on the Arkansas economy was estimated for the most recent year available, 2010. Gross Domestic Product (GDP) by State information for Arkansas in 2010 was compared with those of other states in the Southeast U.S. to give a measure of the relative importance of agriculture in Arkansas.2 The total …

Landscape Architecture & Regional Planning Studio and Student Research and Creative Activity
Prelude to a Master Plan offers ideas, recommendations, and a toolkit to help the town chart its own path towards that future. While the teams and individual students worked to ‘drill down’ into specific topic areas, the Studio defined three basic areas in order to think about how the various assets, challenges and ideas undermine or reinforce one another. The report is loosely organized in those terms: addressing the outlying rural areas and issues specific to these places, considering one of the key growth areas that has extended from town and the conflicts that arise from the many uses occurring …

Facilitation Drives Mortality Patterns Along Succession Gradients Of Aspen-Conifer Forests, W. John Calder, Samuel B. St. Clair
Facilitation Drives Mortality Patterns Along Succession Gradients Of Aspen-Conifer Forests, W. John Calder, Samuel B. St. Clair
Aspen Bibliography
While it is well established that facilitation and competition are important structuring forces in plant communities, a clear understanding of the interactions between them and how they change through the life stages of plants and affect long-term plant community development is lacking. We have observed that conifer seedlings are rarely found growing in meadows but readily establish under adjacent aspen stands, particularly at the base of aspen trees, creating the potential for antagonistic interactions in later life stages. To examine these relationships and their potential consequences on forest community development, we characterized patterns of establishment, regeneration, and overstory mortality of …

Decision Memo: Pando Aspen Clone Restoration Project, Kurt Robins
Decision Memo: Pando Aspen Clone Restoration Project, Kurt Robins
Aspen Bibliography
The Pando Clone is located in Township 26 South, Range 1 East, Sections 24 and 25 about 1 mile southwest of the Lakeside Resort on State Highway 25 and about 1 mile due east of Mallard Bay at the southwest corner of Fish Lake (see map). The Pando Clone is the largest aspen clone in the world and the largest (most massive) single living organism in existence that has been discovered to date (Grant, 1993; DeWoody et al, 2008). It encompasses approximately 106 acres and is estimated to weigh in excess of 13 million pounds (Grant, 1993). This clone is …
