Comparison Of Understory Chemical And Mechanical Treatments To Promote Regeneration Of Desirable Forestland Species, Rebecca Rachael Tyler

MSU Graduate Theses

Invasive woody plants and trees can have a negative impact on desired tree regeneration in the understory of forest stands, and forage density in grassland sites. An assessment of chemical and mechanical treatments on woody plants in the understory of forestland and in grassland is needed. Two experiments were set up in two forest stands and in two grassland/forest edge sites, with two treatment times during the growing season in the first year of the study. On the forestland sites, chemical and mechanical treatments were applied on undesired woody plants to see if they effect the regeneration of desired tree …

The Impact Weather Has On Nyc Citi Bike Share Company Activity, Mark Martinez

Journal of Environmental and Resource Economics at Colby

This paper seeks to figure out the effect weather has on individuals’ behavior. A more focused approach to determining this effect is seeing how different weather conditions ranging from the temperature, the precipitation, the amount of inches of snowfall and the wind speed effect the ridership of Citi Bikes throughout all four seasons. The approach of this research paper is using data from the National Climatic Data Center that focuses in on the weather found in Manhattan, New York and correlates each of the weather conditions to the total number of trips per day that is provided by the Citi …

The Effects From Public Transportation On Property Values: A Closer Look At Scituate, Hanover, And Norwell, Massachusetts, Alexandra Taylor Perticone, Christine S. Coveney

Journal of Environmental and Resource Economics at Colby

Prior studies have expressed the value of location in real estate, but more recent studies have explored the influence that public transportation has had on housing prices. Access to public transportation is understood to increase the value of homes. Easier access to public transportation allows for shorter and more convenient commutes into or within cities. However, other studies have found that proximity to public transportation can also have adverse effects on property values. This paper investigates whether the implementation of the Greenbush Commuter line in Massachusetts in October 2007 increased the housing prices in Scituate, Ma--the furthest town from the …

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

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, …

In Vitro Production Protocol Of Vaccinium Uliginosum L. (Bog Bilberry)Growing In The Turkish Flora, Mustafa Cüce, Atalay Sökmen

Turkish Journal of Agriculture and Forestry

This novel approach was designed to increase the production capacity of Vaccinium uliginosum L. via direct organogenesis. Lateral buds containing one or two leaves were initially cultured in McCown woody plant medium (WPM), Anderson's rhododendron medium, and Murashige and Skoog basal media, each supplemented with zeatin/indole-3-butyric acid (IBA) and zeatin/naphthalene acetic acid (NAA) (1.0/0.1 mg L-1). WPM containing the zeatin/IBA combination was the most effective as the basal medium. Various plant growth regulators (PGRs) were then investigated for the best shoot multiplication, and zeatin was found to be most favorable PGR in all cases. The highest shoot length and shoot …

The experiment was conducted on four oilseed rape genotypes (Banacanka, Jasna, Kata, and Zlatna) in semicontrolled conditions in containers with three soil types: chernozem, solonetz, and solonchak. The germination failed on solonchak due to the excessive amount of salt, but results were obtained for plant material on …

The Influence Of Native Woody Species, Combretum Glutinosum And Piliostigma Reticulatum, On Soil Fertility In Dialacoto, Senegal, Gwen Jacobson

Dissertations, Master's Theses and Master's Reports

In the low-fertility soils of Senegal, West Africa, management of woody species in agricultural fields has the potential to improve soil fertility and crop production. However, optimal species for this purpose have not been clearly defined. Thus, the objective of this study was to evaluate the potential for two native woody species, Combretum glutinosum and Piliostigma reticulatum, to improve soil fertility. Soil samples were collected from beneath tree crowns of P. reticulatum and C. glutinosum and compared with fertilizer-amended and non-amended soil from adjacent open fields in a bioassay experiment. Two common crops, millet (Pennisetum glaucum) and maize (Zea mays), …

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

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 …

Bud Management Affects Fruit Wood, Growth, And Precocity Of Cherry Trees, İdri̇s Maci̇t, Gregory A. Lang, Hüsnü Demi̇rsoy

Turkish Journal of Agriculture and Forestry

As the production benefits of pruning fruit trees have been realized, growers have begun pruning periodically and, accordingly, various canopy training systems have begun to be developed. Following the genetic development of dwarfing rootstocks, interest has grown in the creation of modern training systems for smaller, more efficient orchards. During the formation of these training systems, it became apparent that branches of a certain size can alter the partitioning of growth resources (nutrients and carbohydrates) within the tree, delaying the formation of the target canopy structure as well as fruit bearing. In recent years, studies have focused on management of …
