Effectiveness Of Delayed Brush Cutting And Herbicide Treatments For Vegetation Control In A Seven-Year-Old Jack Pine Plantation In Northwestern Ontario, Canada, Azim U. Mallik, F. Wayne Bell, Yanli Gong

Aspen Bibliography

Efficacy of three conifer release treatments, i) single application of glyphosate (Vision™) herbicide, ii) multiple application of glyphosate herbicide, and iii) motor-manual brush cutting for controlling competing plants, particularly trembling aspen (Populus tremuloides), pin cherry (Prunus pensylvanica), green alder (Alnus viridis spp. crispa), and beaked hazel (Corylus cornuta spp. cornuta), was studied in a seven-year-old jack pine (Pinus banksiana) plantation in northwestern Ontario, Canada. The single and multiple glyphosate applications were equally effective in controlling trembling aspen and pin cherry, causing over 90% stem mortality. The brushsaw treatment caused an initial decrease followed by an increase in stem density of …

Natural Fire Regime: A Guide For Sustainable Management Of The Canadian Boreal Forest, Yves Bergeron, Alain Leduc, Brian D. Harvey, Sylvie Gauthier

Aspen Bibliography

The combination of certain features of fire disturbance, notably fire frequency, size and severity, may be used to characterize the disturbance regime in any region of the boreal forest. As some consequences of fire resemble the effects of industrial forest harvesting, conventional forest management is often considered as a disturbance that has effects similar to those of natural disturbances. Although the analogy between forest management and fire disturbance in boreal ecosystems has some merit, it is important to recognise that it also has its limitations. Short fire cycles generally described for boreal ecosystems do not appear to be universal; rather, …

Using Gis For Forest Recreation Planning On The Longleaf Ridge Special Area Of The Angelina National Forest, East Texas, I-Kuai Hung

Faculty Publications

Longleaf Ridge Special Area (LRSA) located in the Angelina National Forest is the westernmost example of a longleaf pine savanna community. Ecologically, the area is one of the most diverse communities in Texas. Due to its size, abundant natural and historical resources, numerous outdoor recreation opportunities exist. In this study, GIS was used to develop a forest recreation concept plan on LRSA. Most of the geospatial data came from public entities. Information for demand analysis on forest recreation was obtained from the 2000 National Survey on Recreation and the Environment database. U.S. Forest Service recreation fee envelope data were analyzed …

Pre-Logging Liana Cutting Reduces Liana Regeneration In Logging Gaps In The Eastern Brazilian Amazon, Jeffrey J. Gerwing, Christopher Uhl

Environmental Science and Management Faculty Publications and Presentations

The cutting of all lianas prior to logging is a reduced-impact logging technique that is predicted to reduce liana proliferation in logging gaps. This study compares liana abundance and species composition in gaps created during conventional and reduced-impact logging in a forest of the eastern Brazilian Amazon. Logging treatments were conducted in side-by-side plots. Shortly following logging, 50-m² plots were located in the approximate centers of four single treefall and four multiple treefall gaps in each logging area. Six years following logging, there were ∼40% fewer climbing lianas in reduced-impact gaps than in conventional logging gaps. In both logging …

Development Of Water-Based Ink System For Braille Printing, Saurabh Varma

Masters Theses

The most commonly used system of writing by and for blind persons is called Braille, named after its French inventor, Louis Braille (1809-1952). Braille is comprised of a rectangular six-dot cell on its end, with up to 63 possible combinations using one or more of the six dots. Braille is the only reliable method of literacy for blind persons, because it enables them to read and write by touch¹.

Currently, Braille is printed by special embossers that serve as a printing press. These embossers create Braille output when it is attached appropriately to computers. The speed of these …

Understory Species Patterns And Diversity In Old-Growth And Managed Northern Hardwood Forests, Robert M. Scheller, David J. Mladenoff

Environmental Science and Management Faculty Publications and Presentations

Forest management can significantly affect both the diversity and spatial patterning of understory vegetation. However, few studies have considered both diversity and spatial patterning at a stand scale. Our objective was to evaluate the effects of forest management on understory plant communities in northern hardwood forests and assess the processes governing differences in species composition, diversity, and spatial patterns. We sampled understory vegetation (all speciestall) and percentage of light transmission levels in three forest types in 12 mesic northern hardwood stands in northern Wisconsin and the Upper Peninsula of Michigan, USA: old-growth, undisturbed forests; even-aged forests resulting from clearcut logging …

Chrysomela Scripta, Plagiodera Versicolora (Coleoptera: Chrysomelidae), And Trichoplusia Ni (Lepidoptera: Noctuidae) Track Specific Leaf Developmental Stages, D.A. Wait, J.S. Coleman, C.G. Jones

Aspen Bibliography

It is well recognized that host-specialized folivores prefer to feed on young in comparison to old leaves. However, the capacity of young leaf feeders to track specific leaf developmental stages has not been clearly demonstrated. Using three insect folivores and two plant species, we show that nitrogen (N) fertilization changes leaf development and that herbivores track these changes in leaf development. Nicotiana tabacum L. and Populus deltoides Bartram were fertilized at two and three rates of N addition, respectively. Plants with high rates of N supply had faster growth, greater leaf area, and faster leaf initiation rates than plants receiving …

Longevity Record For A Wild Allegheny Woodrat (Neotama Magister) In West Virginia, Michael T. Mengak, Steven B. Castleberry, W. Mark Ford, Nikki L. Castleberry, Jane L. Rodrigue

Virginia Journal of Science

The Allegheny woodrat (Neotoma magister) is found throughout much of the central and southern Appalachians and adjacent portions of the Interior Highlands. Allegheny woodrats have declined in the northern portions of their range and are state-listed as threatened, endangered or sensitive species of concern in every state where they occur. Until recently, biologists have had to rely on biological data collected from the closely related eastern woodrat (N. floridana) because of limited research on the Allegheny woodrat. We have been studying the ecology and natural history of woodrats in Virginia and West Virginia since 1990. On …

An Assessment Of Potential Habitat Corridors And Landscape Ecology For Long-Tailed Macaques (Macaca Fascicularis) On Bali, Indonesia, Mark Warren Southern

All Master's Theses

The relationship between Balinese long-tailed macaques, Bali's cultural settings, and Bali's physical settings was studied. A Geographical Information System (GIS) database was developed and analyzed to determine if forest corridors exist on Bali that may provide habitat connectivity between 42 Balinese long-tailed macaque troops. The GIS database was also analyzed to determine if the landscape type that has the highest percentage of overlap with the 42 Balinese long-tailed macaque home range sites is forest. The results indicate that connectivity between troops located within Bali's western region is significantly higher than that for troops located in Bali's eastern region. The results …

Compositional Trends And Spatial Patterns Over A Quarter Century: Forest Dynamics Of Dobbs Park, Indiana, Nancy Hoalst Pullen

All-Inclusive List of Electronic Theses and Dissertations

Thirty-five permanent plots were reexamined to identify and describe the spatial and temporal characteristics of Dobbs Park, an isolated old-growth forest stand in westcentral Indiana. The 3.6 ha stand was resurveyed in summer 2000, with all stems greater than 10 cm dbh measured, and accessions and deaths recorded. The results are compared to original data collected in summer 1974, with compositional and spatial patterns identified via GIS and spatial analysis. The stand has declined slightly in density from 342 stems/ha to 333.15 stems/hectare (-2.6%) while basal area (dominance) for the stand has increased from 23.6 m2/ha to 25.8 m2/ha (+8.8%) …

Rheology Of Silica Based Inkjet Coatings And Their Filterability, Peeyush Tripathi

Masters Theses

Coating rheology has long been understood to be a key factor in the smooth operation and performance of a coater. As coaters run faster and formulations become more complex, the demands on a coating's rheology grow more stringent.

Silica based coating formulations present unique rheological challenges, thus providing the opportunity for coating formulators to improve their performance through rheological studies under various conditions of shear. Due to rheological restrictions (gelling), silica based coatings are generally applied at 25-26% solids which is very low as compared to calcium carbonate or clay based coating, at 68-70% solids. Consequently, any improvement in coatings …

Uv-Vis Spectral Analysis Of Spot Colors, Radovan Sporka

Masters Theses

Press return inks represent a continuous problem in printing industry. The best way of utilizing them is to mix them into new colors. Efficiently to do so, it is necessary to determine their composition first. The spot color inks for product gravure were analyzed using Perkin Elmer Spectrometer LAMBDA 900. UV/VIS/NIR analysis of mixtures showed rather similar course of ink spectra in ultraviolet and near infrared region. Thus, the VIS range from 400 - 700 nm was used for further analysis. The unique course of spectral curves of each pigment in visible region enabled successful qualitative analysis of two- and …

Biotechnical Streambank Protection: The Use Of Plants To Stabilize Streambanks, Gary W. Wells

Agroforestry Notes (USDA-NAC)

Biotechnical streambank protection utilizes living plant materials to reinforce soil and stabilize slopes. Plants can be used as the primary structural component or in combination with inert materials like rock, concrete, and steel to help stabilize streambanks. Many terms have been used to describe the engineering use of plant materials for slope stabilization (Figure 1). The Natural Resources Conservation Service (NRCS) uses the term Soil Bioengineering to describe the use of living plant material for soil reinforcement, hydraulic drains, barriers to earth movement, and hydraulic pumps or wicks. The underlying concept for all terms is the use of plants to …
