Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2007 And Revised Estimates For 2006, Nathan Kemper, Jennie Popp, Wayne Miller
Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2007 And Revised Estimates For 2006, Nathan Kemper, Jennie Popp, Wayne Miller
AAES Research Reports and Research Bulletins
This report is the fourth in a series of reports examining agriculture’s economic contribution on the Arkansas economy. Utilizing data from the United States Bureau of Economic Analysis, USDA Economics Research Service, USDA National Agricultural Statistics Service, and Minnesota IMPLAN Group, Inc., the economic contribution of agriculture on the Arkansas economy was estimated for the most recent year available, 2007. Gross Domestic Product (GDP) by State information for Arkansas was compared with those of other states in the southeast U.S. to give a measure of the relative importance of agriculture in Arkansas. The total economic contribution of agriculture (direct, indirect, …
Forest Change And Balsam Woolly Adelgig Infestation In High Elevation Forests Of Mt. Mitchell, North Carolina., Laura Lusk
Undergraduate Honors Theses
The Black Mountain range of western North Carolina supports some of the most extensive, but threatened high elevation forests in the southern Appalachians. Of particular note, the insect pathogen, balsam woolly adelgid (Adelges piceae Ratzeburg) has been present on Mt. Mitchell for over fifty years. In anticipation of potential changes in forest composition, vegetation surveys were first conducted in 1966 on nine one-acre plots near the summit of Mt. Mitchell. These plots were re-surveyed in 1978, 1985 and 2002. The purpose of this study was to re-census those plots and use those data to analyze long-term trends in forest …
A Powerful New Planning Environment For Fuels Managers: The Interagency Fuels Treatment Decision Support System, Gail Wells
Joint Fire Science Program Digests
The Joint Fire Science Program, the National Wildfire Coordinating Group Fuels Management Committee, and Sonoma Technology, Inc. are unveiling the prototype of a new planning environment that will help fuels specialists negotiate the confusing array of planning tools. The new framework, dubbed the Interagency Fuels Treatment Decision Support System, or IFT-DSS, organizes fuels-planning software and data into a seamless user environment. IFT-DSS offers users access to powerful modeling software from within a well-designed, intuitive graphical user interface, and it provides a common platform for the further development of fuels-planning software tools. The name may not slide easily off the tongue—you …
Analysis Of A Pinus Radiata Seed Stock Field In The Native Año Nuevo Stand In California, Christina Brassey
Analysis Of A Pinus Radiata Seed Stock Field In The Native Año Nuevo Stand In California, Christina Brassey
Master's Theses
This study was a part of the international collaborative IMPACT project, which aims to address the potential threat that the pitch canker disease poses to the use of Pinus radiata D. Don in plantations in New Zealand, Australia, and Chile. A field trial of 264 seedstocks was planted adjacent to a native stand of pitch canker infected P. radiata on the central coast of California, and disease symptom development was recorded over a period of 3 years. The results did not correlate with a greenhouse study of the same seedstocks inoculated with Fusarium circinatum Nirenberg & O'Donnell, the causal agent …
Transferability Of Simple Sequence Repeat (Ssr) Markers Developed In Litchi Chinensis To Blighia Sapida (Sapindaceae), Marius R.M. Ekué, Oliver Gailing, Reiner Finkeldey
Transferability Of Simple Sequence Repeat (Ssr) Markers Developed In Litchi Chinensis To Blighia Sapida (Sapindaceae), Marius R.M. Ekué, Oliver Gailing, Reiner Finkeldey
Michigan Tech Publications, Part 1
Ackee (Blighia sapida, Sapindaceae) is a multipurpose fruit tree species of high economic importance, native to the Guinean forests of West Africa, and belongs to the same family as that of lychee (Litchi chinensis). In this study, a set of 12 primer pairs for simple sequence repeats (SSRs) previously developed for lychee has been evaluated for polymorphism in 16 ackee trees from different populations. Seven primer pairs have been found to be transferable, and four have revealed polymorphisms. However, the average number of alleles per locus has dropped from 4.9 for lychee to 3.7 for ackee. Characterization of the four …
Disturbance Ecology And Vegetation Dynamics At Varying Spatial And Temporal Scales In Southern Rocky Mountain Engelmann Spruce Forests, R. Justin Derose
Disturbance Ecology And Vegetation Dynamics At Varying Spatial And Temporal Scales In Southern Rocky Mountain Engelmann Spruce Forests, R. Justin Derose
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
High-severity disturbances are the primary drivers of Engelmann spruce-subalpine fir ecosystems in the southern Rocky Mountain. Recently, an unprecedented, landscape-wide (at least 250 km2) spruce beetle outbreak killed virtually all the Engelmann spruce on the Markagunt Plateau in southwestern Utah, USA. Results from dendroecological analyses suggested the combination of antecedent disturbance history and drought-driven stand development was responsible for creating suitable host conditions prior to the recent outbreak. Multiple and consistent lines of evidence suggested mixed- and high-severity fires shaped the development of the Markagunt Plateau. Subsequent stand development, influenced by species-specific differential tree-ring response to drought, resulted in the …

Regional Assessment Of Aspen Change And Spatial Variability On Decadal Time Scales, Temuulen Tsagaan Sankey
Regional Assessment Of Aspen Change And Spatial Variability On Decadal Time Scales, Temuulen Tsagaan Sankey
Aspen Bibliography
Quaking aspen (Populus tremuloides) is commonly believed to be declining throughout western North America. Using a historical vegetation map and Landsat TM5 imagery, this study detects changes in regional aspen cover over two different time periods of 85 and 18 years and examines aspen change patterns with biophysical variables in the Targhee National Forest of eastern Idaho, USA. A subpixel classification approach was successfully used to classify aspen. The results indicate greater spatial variability in regional aspen change patterns than indicated by local-scale studies. The observed spatial variability appears to be an inherent pattern in regional aspen dynamics, …

Guide Accreditation In The Wet Tropics World Heritage Area: A Study Of The Practices, Attitudes, And Concerns Of Small Tourism Operators, Nora Vogel
Independent Study Project (ISP) Collection
This study assessed the attitudes, practices, and needs of tour operators in the Wet Tropics World Heritage area with respect to the recruitment and training of tour guides. The results will be used to help determine the need and demand for an official Wet Tropics guide accreditation system, as well as the form that system should take. The study also served to add more contacts to the Wet Tropics Management Authority’s growing network of tour operators, tour groups, and research scientists. Tour operators’ guide training practices varied with their business type and resources; many of the smallest operators provided a …
