Protecting Degraded Rainforests: Enhancement Of Forest Carbon Stocks Under Redd+, David P. Edwards, Brendan Fisher, Emily Boyd

Rubenstein School of Environment and Natural Resources Faculty Publications

The likely Reducing Emissions from Deforestation and Degradation (REDD+) mechanism includes strategies for the enhancement of forest carbon stocks. Recent concerns have been expressed that such enhancement, or restoration, of forest carbon could be counterproductive to biodiversity conservation, because forests are managed as "carbon farms" with the application of intensive silvicultural management that could homogenize diverse degraded rainforests. Restoration increases regeneration rates in degraded forest compared to naturally regenerating forest, and thus could yield significant financial returns for carbon sequestered. Here, we argue that such forest restoration projects are, in fact, likely to provide a number of benefits to biodiversity …

The Perfect Spill: Solutions For Averting The Next Deepwater Horizon, Robert Costanza, David Batker, John W. Day, Rusty A. Feagin, M. Luisa Martinez, Joe Roman

Institute for Sustainable Solutions Publications and Presentations

In this article the authors comment on the oil spill incident from the Deepwater Horizon, particularly on its economic and ecological damages. The authors highlighted the disaster as an event wherein much is needed to be learned so that future oil spills can be avoided. One lesson refers to the valuability of natural capital assets and other public entities that are at risks due to private interests and that better regulations and incentives are needed to protect these assets against risks.

Design Of A New Suturing And Knot Tying Device For Laparoscopic Surgery, Sinan Onal

USF Tampa Graduate Theses and Dissertations

Minimally invasive or laparoscopic surgery has completely changed the focus of surgery becoming an alternative to various types of open surgery. Minimally invasive surgery avoids invasive open surgery as the operation is performed through one or more small incisions in the abdomen and using a small camera called laparoscope. Through these incisions, surgeons insert specialized surgical instruments to perform the operation resulting in less postoperative pain, shorter hospital stay, and faster recovery. However, the main problems during minimally-invasive surgery are the limited space for operating instruments and the reduced visibility and range of motion inside the patient’s body. During minimally-invasive …

Construction Cost Models, Barry Dikeman

Economics and Finance

The following are a series of cost estimate models similar in format to a typical engineer’s estimate that were developed in support of our financial impact assessment report for LD 1725. The models us current material costs, labor costs, and equipment costs for the region to provide a comparative cost analysis of seven culvert replacement scenarios. The models provide information about what the cost impact of LD 1725 would be for typical culvert replacements in Maine. However, due to the inherent restrictions of the cost modeling framework we were not able to include the abundance of variables that would be …

Knowing Your Community: Fostering Biodiversity Awareness In Our Students’ Daily Existence, Tony Cummings Bs, Academic Director

Fostering Multicultural Competence and Global Justice: an SIT Symposium

There are strong arguments suggesting that developing students’ sensitivity to local biodiversity and conservation issues is as important as emphasizing an understanding of global conservation issues happening in faraway lands (Ehrenfeld, 2009). Many students arrive at a Study Abroad destination, with a good understanding of theory, but with little field experience at home. Environmental educators in Study Abroad are able to use the novelty and grandeur of our exotic destinations to systematically teach students the patterns and processes of ecological and human communities at our sites, while inspiring a sense of place in our students. By immersing students in the …

Environmental Sustainability: Challenges And Opportunities Of Greening Your Study Abroad Program, Sylvia M. Seger Mim, Academic Director

Fostering Multicultural Competence and Global Justice: an SIT Symposium

World Learning’s mission to “… create a more peaceful and just world” by necessity encompasses environmental dynamics, considering that the root causes of most social justice issues and violent conflicts can be traced to environmental degradation and disproportional access to shrinking natural resources. Thus our mission mandates that we employ an ethic of environmental stewardship in all our pursuits and put in place mechanisms to mitigate our environmental impacts.

“We shall never achieve harmony with land, any more than we shall achieve absolute justice or liberty for people. In these higher aspirations, the important thing is not to achieve but …

Steps Toward Butternut (Juglans Cinerea L.) Restoration, Sunshine L. Brosi

Doctoral Dissertations

Butternut (Juglans cinerea L.), a lesser-known relative of black walnut (Juglans nigra L.), is a native tree species beneficial for wildlife, valuable for timber, and part of the great diversity of species in the eastern forests of North America. Populations of butternut are being devastated by butternut canker disease, caused by the fungus Sirococcus clavigignenti-juglandacearum (V.M.G. Nair, Kostichka, & Kuntz), which is thought to be introduced to North America. The disease causes multiple branch and stem cankers that eventually girdle trees. Small population sizes, lack of sprouting, and shade intolerance exacerbates the disease and results in permanent losses of butternut …

Effects Of 2000-2050 Global Climate Change On Ozone And Particulate Matter Air Quality In The United States Using Models-3/Cmaq System, Yun-Fat Lam

Doctoral Dissertations

The Models-3/Community Multi-scale Air Quality modeling system (CMAQ), coupled with Goddard Institute for Space Studies (GISS) atmospheric General Circulation Model (GCM), fifth Generation Mesoscale Model system (MM5), and Goddard Earth Observing System-CHEMistry (GEOS-Chem), was used to simulate atmospheric concentration of ozone and particulate matter over the continental United States 12-km and 36-km (CONUS) domains at year 2000 and year 2050. In the study, GISS GCM model outputs interfaced with MM5 were utilized to supply the current and future meteorological conditions for CMAQ. The conventional CMAQ profile initial and boundary conditions were replaced by time-varied and layer-varied GEOS-Chem outputs. The future …

Publications

Despite a growing recognition that the solutions to current environmental problems will be developed through collaborations between scientists and stakeholders, substantial challenges stifle such cooperation and slow the transfer of knowledge. Challenges occur at several levels, including individual, disciplinary, and institutional. All of these have implications for scholars working at academic and research institutions. Fortunately, creative ideas and tested models exist that provide opportunities for conversation and serious consideration about how such institutions can facilitate the dialogue between scientists and society.

Temporal And Spatial Monitoring Of Mobile Nanoparticles In A Vineyard Soil: Evidence Of Nanoaggregate Formation, N. Perdrial, J. N. Perdrial, J. E. Delphin, F. Elsass, N. Liewig

College of Arts and Sciences Faculty Publications

Mechanisms of formation, stabilization, liberation, transport and deposition of nanoparticles and their relationship to contaminant transport remain scarcely investigated in natural porous media. This study investigated nanoparticles mobilized in the pore space of a French vineyard soil by observing mobile soil-derived organic matter (SOM) and minerals in pore fluids over an 8-month monitoring period. Samples were collected in situ and investigated by transmission electron microscopy coupled to electron-dispersive spectroscopy. The main types of nanoparticles transported within the soil were clay, bacteria, SOM and nanoaggregates. Nanometric clay particles were enriched in various metals (Fe, Zn, As and Pb) and organically-derived constituents. …

Climate Change And Globalization In The Americas: Case Studies Of Mitigation And Adaptation, Mary Finley-Brook, Melissa Haeffner, Charmaine Heslop-Thomas, Elma Montaña, Leah Sprain

Environmental Science and Management Faculty Publications and Presentations

Robin Leichenko and Karen O‘Brien have proposed ―double exposure‖ as a conceptual framework to demonstrate how processes of globalization and global environmental change (GEC) redefine risk and encourage new, interrelated responses to social and ecological transitions (O‘Brien and Leichenko, 2000; Leichenko and O'Brien, 2008). In particular, the concept encourages researchers and policy makers to consider interplay between global climate change and globalization and how this is expressed unevenly across space. After reviewing the ways double exposure has been used in the literature, we consider four case studies to investigate the utility of the framework for analyzing and understanding climate change …

Algal Biomass Accrual In Relation To Nutrient Availability Along A Longitudinal Gradient In The Upper Green River, Kentucky, Mary Douglas Penick

Masters Theses & Specialist Projects

Nutrient limitation in aquatic ecosystems results from a deficiency in nitrogen or phosphorus levels relative to cellular growth needs. Nutrient limitation of freshwater systems is a function of biotic and abiotic factors. Biotic factors include vascular and nonvascular plant community composition. Abiotic factors include underlying bedrock and land-use activities (e.g. agriculture, septic systems). Nutrient availability directly affects growth, productivity, and community structure of primary producers. The purpose of this study was two-fold: (1) to assess the relationship between ambient algal biomass. and in-stream nutrient levels along the longitudinal course of a river through a transition from weak to well-developed underlying …

Wind Flow Modeling For Wind Energy Analysis Of The Nellis Dunes Area In Nevada, Upendra Rangegowda

UNLV Theses, Dissertations, Professional Papers, and Capstones

A wind energy analysis of the Nellis Dunes area in Nevada was conducted. A DEM file which contains the elevation data was used to generate the surface model and to create a 3-D mesh of the region. Local meteorological tower data collected for a period of one year was used to generate the diagnostic initial wind fields. Upper level wind fields were created using a surface boundary layer technique along with linear interpolation of the tower level wind fields. The vertical components of the velocities were adjusted using the equation of continuity. Mass consistent 3-D wind fields were then calculated …
