Standard-Level Herbivory In An Old-Growth Conifer Forest Canopy, David C. Shaw, Kristina A. Ernest, H. Bruce Rinker, Margaret D. Lowman

All Faculty Scholarship for the College of the Sciences

Herbivory is an important ecological process in forest canopies but is difficult to measure, especially for whole stands. We used the Wind River Canopy Crane in Washington State to access 101 randomly-located sample points throughout the forest canopy. This provided a relatively quick and convenient way to estimate herbivory for a whole stand. The overall level of herbivory was estimated at 1.6% of leaf area. The distribution was strongly skewed to the lower canopy where broad-leafed species experienced higher levels of herbivory. Herbivory averaged 0.3% in conifers and 13.5% in broad-leafed species. Fully half of the sample points had no …

Tb195: Element Concentrations In Maine Forest Vegetation And Soils, Chandra J. Mcgee, Ivan J. Fernandez, Stephen A. Norton, Constance S. Stubbs

Technical Bulletins

Bioaccumulation of trace metals in plant tissues can present a health risk to wildlife, and potentially to humans. The Passamaquoddy Tribe in Maine was concerned about health risks of cadmium (Cd) because of a health advisory for moose liver and kidney consumption due to high Cd levels. In addition to Cd, this study evaluated concentrations of aluminum (Al), calcium (Ca), copper (Cu), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), nickel (Ni), phosphorus (P), lead (Pb), and zinc (Zn) in four common terrestrial moose-browse species, associated forest soils, and two species of aquatic vegetation on Passamaquoddy tribal land in eastern …

Enhanced Print Performance Of Water-Based Rotogravure Inks Through Rheological Balance, Rurou Mai

Masters Theses

Water-based inks have been of more and more interest to the printing and ink industry. Compared with solvent-based inks, water-based inks have more complex formulations because of their higher surface tensions, lower drying speed, foaming problems, pH balance, and different rheological properties. This work explores the significant effects of various rheology modifiers, including non-associative and associative thickeners, on the rheological properties of a water-based rotogravure ink system. Particular emphasis is given to thickening efficiency, pH stability, particle size, system compatibility, temperature stability, and printability on vinyl substrates. Wire-wound lab rods and a Moser Sheet-fed Gravure Proofing Press were employed to …

Surface Topography Contribution To Rfid’S Tags Efficiency Related To Resistivity, Mario A. Cruz

Masters Theses

The Radio Frequency Identification (RFID) is one of the new technologies with more vision and acceptance oriented to the distribution and storage industries. The RFID is a technology that can be used to identify, track and store information about groups of products, individual items, or product components, using radio waves. The RFID device needs an antenna in order to receive a signal and transmit information. The stamping process applied today to produce the RFID antenna works with foil or copper. These etched metal RFID tags offer good benefits, but the production cost is too high to achieve a widespread implementation. …

Caustic Treatment Of The Pulp: Caustic Recovery By Reverse Osmosis, Miroslav Suchy

Masters Theses

The benefit of caustic treatment on changing cellulose properties has long been known. When the treated pulp is later intended for use in personal or in health care product industries, it is important that all residual chemicals are removed and that the pure cellulose or carbohydrate portion of the pulp remains. The removal is usually facilitated by washing. Due to the low caustic concentration in the washing filtrates the removal of the excess water by standard techniques such as evaporation would not be economical.

The main objective of this investigation was to evaluate the concept of using reverse osmosis for …

Policy Tools For Smart Growth In New England, New England Environmental Finance Center

Smart Growth

Across New England communities have been experiencing a rapid outward surge of development away from our community and downtown centers. Effects of sprawl include a loss of wildlife habitat, farm and timber lands; increased costs of community services and higher taxes; auto-dependency, longer commutes, and increased congestion; increases in air and water pollution; a sedentary lifestyle and increased obesity; and losses to one’s sense of place and social ties.

State-level responses to sprawl have surfaced throughout New England in recent years. This report describes 11 examples of these responses, representing all six New England states and a diversity of recent …

Changes In Understory Vegetation Of A Ponderosa Pine Forest In Northern Arizona 30 Years After A Wildfire, Amanda L. Bataineh, Brian P. Oswald, Mohammad M. Bataineh, Hans M. Williams, Dean W. Coble

Faculty Publications

Wildland fires can cause shifts in understory species composition and production. Many studies have examined short-term changes in understory vegetation following a wildfire; however, very few long term studies are available. The objective of this study was to examine changes in understory (herb and shrub) species composition and production since the 1972 Rattle Burn wildfire on the Coconino National Forest near Flagstaff, Arizona. Understory species composition and production were originally sampled in 1972, 1974, and 1980 and were re-sampled during July and August of 2002 and 2003 on 30 plots in each of four sites: high severity burn, low severity …

An Approach For Using Soil Surveys To Guide The Placement Of Water Quality Buffers, Mike Dosskey, Matthew J. Helmers, Dean E. Eisenhauer

USDA Forest Service / UNL Faculty Publications

Vegetative buffers may function better for filtering agricultural runoff in some locations than in others because of intrinsic characteristics of the land on which they are placed. The objective of this study was to develop a method based on soil survey attributes that can be used to compare soil map units for how effectively a buffer installed in them could remove pollutants from crop field runoff. Three separate models were developed. The surface runoff models for sediment and for dissolved pollutants were quantitative, based mainly on slope, soil, and rainfall factors of the Revised Universal Soil Loss Equation (RUSLE), and …

Response Of The Herbaceous Layer Of Forest Ecosystems To Excess Nitrogen Deposition, Frank S. Gilliam

Biological Sciences Faculty Research

• 1 This review brings into focus what is known about the response of the herbaceous layer of forest ecosystems to increasing nitrogen deposition. The emphasis on forests in general is important for two reasons. First, forests often occupy areas receiving high rates of atmospheric deposition of N. Second, compared with herb-dominated communities, about which much is known regarding response to excess N, forests generally display greater biological and structural complexity. The more specific focus on the herbaceous layer – here defined as all vascular (herbaceous and woody) plants ≤ 1 m in height – is warranted because most of the …

Fire Making Fuel: How A Surface Fire In A Primary Forest Affected The Availability Of Potential Fuel One Year Later, Alex Leckie

Independent Study Project (ISP) Collection

Fires affect millions of hectares of tropical forests around the world. These fires result in great environmental damage and economical losses. Many farmers are dependent on fire for managing their lands and many times their fires accidentally spread into forests via fuels on the forest floor. This study attempted to analyze and quantify the difference of potential fuel in a primary forest which burned one year before and an unburned part of the same forest at a primary forest fragment surrounded by farms and with a history of anthropogenic accidental fires burning it. This was done by making three sample …

Working Trees For Water Quality

Working Trees (USDA-NAC)

Water is a precious national resource. Often, human activities degrade the quality of the water in the streams, lakes, estuaries, wetlands, and aquifiers on which we depend. Pollutants from agricultural and urban sources have made many of our waters unsuitable for swimming and fishing. Excessive sedimentation, pesticides, and fertilizers are harming fish and other aquatic life. Changes in land use also have had a dramatic effect on floodwater damage and frequency. Both surface and subsurfaceAgroforestry drinking water supplies are being impacted by human activities.

Water quality is the end result of the individual actions of all the “neighbors” in a …

The Effects Of Prescribed Fire On The Herbaceous Layer In The Southern Appalachian Mountains., Michael Lee Zimmerman

Electronic Theses and Dissertations

Prescribed fire in the southern Appalachians is a frequently used and controversial forest management practice. Research is limited on the effects of prescribed fire in the mesic southern Appalachians, where many of Tennessee's rare and regionally endemic plant species occur. This study examined the effects of prescribed fire on the herbaceous layer. Field work was conducted on six previously burned sites within the Cherokee National Forest in northeast Tennessee. Complimentary non-burned sites were selected based on similarity of physical characteristics and forest structure. The numbers of herbaceous species and individuals and the total numbers of species and individuals were determined …
