Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2015, Leah English, Jennie Popp, Wayne Miller
Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2015, Leah English, Jennie Popp, Wayne Miller
Research Reports and Research Bulletins
Agriculture and associated agricultural activities are major contributors to the Arkansas economy. Agriculture is defined as the sum of agricultural production and processing activities, unless otherwise specified, and includes crop and animal production and processing, agricultural support industries, forestry and forest products, and textile goods. Agriculture contributes to the economy through direct agricultural production and value-added processing, and also leads to economic activity in other parts of the economy. This report is the tenth in a series of reports examining agriculture’s economic contribution to the Arkansas economy. The total economic contribution of agriculture (direct, indirect, and induced effects) on value …
Oystershell Scale Impacts And Mitigation Options On The Kaibab And Coconino Nf’S, Amanda M. Grady
Oystershell Scale Impacts And Mitigation Options On The Kaibab And Coconino Nf’S, Amanda M. Grady
Aspen Bibliography
This report documents a site visit to evaluate aspen stands experiencing oystershell scale damage on the Kaibab and Coconino National Forest’s. The site visit was requested by Kaibab NF, foresters including; Josh Giles, Jessi Outzs, Michael Sedgeman, Woody Rokala and Coconino Silviculturist, Mark Nabel. On November 19, 2016, Amanda Grady accompanied the individuals listed above, to evaluate stand conditions within three aspen exclosures. Two were located on the Williams Ranger District, Kaibab NF in the vicinity of Spring Valley. The third exclosure was located on the Flagstaff RD, Coconino NF and accessed from HWY 89-A via the Pump House Wash …
2015 Maple Business Benchmark, Mark Cannella, Christopher Lindgren, Betsy Miller
2015 Maple Business Benchmark, Mark Cannella, Christopher Lindgren, Betsy Miller
UVM Extension Faculty Publications
The 2015 Maple Business Benchmark is the third year of financial analysis for a small group of commercial syrup producers. The University of Vermont Extension worked with 14 maple producers to complete financial analysis of their maple enterprise. This report demonstrates key management and financial metrics including: yield statistics, land use, operating costs, investment requirements, total cost of production, marketing strategy and net income. The participants represent a small sample of the entire Vermont maple industry but the findings can compel any manager to consider the methods and results of financial analysis for their particular business situations. This report will …
Ecological And Organic Life Safety Concerns Of Hfo-1234yf, Alberni V. Ruiz
Ecological And Organic Life Safety Concerns Of Hfo-1234yf, Alberni V. Ruiz
STAR Program Research Presentations
While at NOAA my research was directed by the inquiry of whether or not HFO-1234yf, a new compound being introduced into coolant system and replacing greenhouse gases HFC, is harmful to organic life. Using the computer program Matlab I was able to develop figures that represented the concentration of HFO-1234yf (HFO) in 12 different tower locations throughout the country. Comparing and contrasting concentrations of this HFO compound at each site led me to the question the possible harmful side effects this compound could bring to organic life due to the fact that concentration levels are increasing, with one factor being …
Species Delimitation And Lineage Separation History Of A Species Complex Of Aspens In China, Honglei Zheng, Liqiang Fan, Richard I. Milne, Lei Zhang, Yaling Wang, Kangshan Mao
Species Delimitation And Lineage Separation History Of A Species Complex Of Aspens In China, Honglei Zheng, Liqiang Fan, Richard I. Milne, Lei Zhang, Yaling Wang, Kangshan Mao
Aspen Bibliography
Species delimitation in tree species is notoriously challenging due to shared polymorphisms among species. An integrative survey that considers multiple operational criteria is a possible solution, and we aimed to test it in a species complex of aspens in China. Genetic [four chloroplast DNA (cpDNA) fragments and 14 nuclear microsatellite loci (nSSR)] and morphological variations were collected for 76 populations and 53 populations, respectively, covering the major geographic distribution of the Populus davidiana-rotundifoliacomplex. Bayesian clustering, analysis of molecular variance (AMOVA), Principle Coordinate Analysis (PCoA), ecological niche modeling (ENM), and gene flow (migrants per generation), were employed to …
Restoration Of The Iconic Pando Aspen Clone: Emerging Evidence Of Recovery, Paul C. Rogers, Jody A. Gale
Restoration Of The Iconic Pando Aspen Clone: Emerging Evidence Of Recovery, Paul C. Rogers, Jody A. Gale
Aspen Bibliography
Quaking aspen (Populus tremuloides Michx.) is being stressed across the America West from a variety of sources including drought, herbivory, fire suppression, development, and past management practices. Rich assemblages of plants and animals that utilize aspen forests, as well as economic values of tourism, grazing, hunting, and water conservation, make aspen ecosystems among the most valuable vegetation types in this region. The 43-ha Pando clone near Fish Lake, Utah, is an iconic example of an aspen community undergoing rapid decline due to overstory mortality and chronic recruitment failure. As part of a larger project to restore Pando, we fenced, …
The Greatest Undertaking: The Unique History Of The Nebraska Forest Service, Tony Foreman
The Greatest Undertaking: The Unique History Of The Nebraska Forest Service, Tony Foreman
Nebraska Forest Service: Publications
Perhaps forests and trees are not the first images one conjures when thinking about Nebraska. Indeed, an old joke claims the Nebraska State Tree is a wooden football goalpost. Yet Nebraska has a unique forestry history. Pioneers of the mid-nineteenth century moved into what was popularly known as the Great American Desert, and they rolled the dice that this semi-arid land, seemingly incapable of sustaining trees, could somehow grow crops. After winning that gamble, the settlers yearned for the trees they had grown accustomed to in the Eastern United States. They missed the beauty of the wooded areas and the …

Maintaining Ecosystem Resilience: Functional Responses Of Tree Cavity Nesters To Logging In Temperate Forests Of The Americas, Jose Tomas Ibarra, Michaela Martin, Kristina L. Cockle, Kathy Martin
Maintaining Ecosystem Resilience: Functional Responses Of Tree Cavity Nesters To Logging In Temperate Forests Of The Americas, Jose Tomas Ibarra, Michaela Martin, Kristina L. Cockle, Kathy Martin
Aspen Bibliography
Logging often reduces taxonomic diversity in forest communities, but little is known about how this biodiversity loss affects the resilience of ecosystem functions. We examined how partial logging and clearcutting of temperate forests influenced functional diversity of birds that nest in tree cavities. We used point-counts in a before-after-control-impact design to examine the effects of logging on the value, range, and density of functional traits in bird communities in Canada (21 species) and Chile (16 species). Clearcutting, but not partial logging, reduced diversity in both systems. The effect was much more pronounced in Chile, where logging operations removed critical nesting …
