Spatiotemporal Variation Of Fruit Digestible-Nutrient Production In Florida's Uplands, J. Layne, W. Abrahamson
Warren G. Abrahamson, II
We examined annual total digestible nutrient (TDN) production by fruits of eight species (Quercus chapmanii, Q. geminata, Q. inopina, Q. laevis, Q. myrtifolia, Carya floridana, Sabal etonia, Serenoa repens) that account for the major proportion of TDN production by fruits and seeds in Florida’s xeric upland associations (southern ridge sandhill, sand pine scrub, scrubby flatwoods). Mean annual fruit TDN of all species combined over a 27-year span in sandhill and scrub and 24 years in scrubby flatwoods was highest (45.4 kg/ha) in sandhill, intermediate in scrubby flatwoods (28.8 kg/ha), and lowest in scrub (14.2 ...
The Effects Of The 1996 U.S.-Canada Softwood Lumber Agreement On The Industrial Users Of Lumber: An Event Study, 2009 University of British Columbia
The Effects Of The 1996 U.S.-Canada Softwood Lumber Agreement On The Industrial Users Of Lumber: An Event Study, Nisha Malhotra, Sumeet Gulati
In this article, we analyze whether the Softwood Lumber Agreement between the United States and Canada imposed significant economic costs on industries that use softwood lumber in the United States. To ascertain this impact, we use an event study. Our event study analyzes variations in the stock prices of lumber-using firms listed at the major stock markets in the United States. We find that the news of events leading to the Softwood Lumber Agreement had significant negative impacts on the stock prices of industries using softwood lumber. The average reduction of stock prices for our sample of firms was approximately ...
Interdisciplinary Research: A Case Study Of Integrating Policy Instruments And Legislations To Address Environmental Changes In Cameroon, Amin Forji, Edinam Glover
Dr. Edinam K. Glover
Integrating policy instruments and legislations to address environmental changes into ongoing development activities has emerged as a major response by international agencies and national governments seeking to promote good environmental and natural resource management. However, the effects of the many causes of environmental changes are worsening and many aspects of what is happening in these ecosystems evade us. Deforestation has for a long time been an acceptable way of life in the Cameroon’s affluent tropical rainforest, which in fact occupies the second largest land mass in the Congo Basin. Just between 1999 and 2005, Cameroon lost an average of ...
The Delimitation Of Flammulina Fennae, 2009 University of Tennessee, Knoxville
The Delimitation Of Flammulina Fennae, Soňa Ripková, Karen Hughes, Slavomír Adamčík, Viktor Kučera, Katarína Adamčíková
Multivariate morphometric analyses of micromorphological characters measured on 35 specimens of Flammulina fennae and related species show that only a combination of spore dimensions and ixohyphidia characters are suitable for delimitation of this species. In order to confirm species identifications based on micromorphology, ribosomal ITS DNA sequences were obtained and compared with those previously deposited in GenBank, and phylogenetic analyses were performed using an ITS dataset of all known Flammulina species. All six specimens morphologically determined as F. fennae were identified by molecular data. Two of twelve specimens morphologically assigned to F. velutipes had F. elastica sequences. One ITS sequence ...
Statistical Contributions To Proteomic Research, 2009 The University of Texas M.D. Anderson Cancer Center
Statistical Contributions To Proteomic Research, Jeffrey Morris, Keith Baggerly, Howard Gutstein, Kevin Coombes
Jeffrey S. Morris
Proteomic profiling has the potential to impact the diagnosis, prognosis, and treatment of various diseases. A number of different proteomic technologies are available that allow us to look at many proteins at once, and all of them yield complex data that raise significant quantitative challenges. Inadequate attention to these quantitative issues can prevent these studies from achieving their desired goals, and can even lead to invalid results. In this chapter, we describe various ways the involvement of statisticians or other quantitative scientists in the study team can contribute to the success of proteomic research, and we outline some of the ...
Viruses In Aquatic Ecosystems: Important Advancements Of The Last 20 Years And Prospects For The Future In The Field Of Microbial Oceanography And Limnology, 2009 University of Tennessee, Knoxville
Viruses In Aquatic Ecosystems: Important Advancements Of The Last 20 Years And Prospects For The Future In The Field Of Microbial Oceanography And Limnology, S. Jacquet, T. Miki Takeshi, R. Nobel, P. Peduzzi, Steven Wilhelm
Over the last two decades, viruses in aquatic systems have been observed to modify, influence and control aquatic systems. Since the determination decades ago that viruses were abundant in aquatic ecosystems, researchers have demonstrated that viruses are pervasive and dynamic across the expanse and depth of all aquatic systems as well as at the water-sediment interface. There have been a wide range of methodological advancements during this time. To date, aquatic viruses have been suggested to play vital roles in global and small-scale biogeochemical cycling, community structure, algal bloom termination, gene transfer, and evolution of aquatic organisms. Even in harsh ...
Influence Of Perinatal Exposure To A Polychlorinated Biphenyl Mixture On Learning And Memory, Hippocampal Size, And Estrogen Receptor-Beta Expression, Howard Cromwell
Howard Casey Cromwell
Abstract. Perinatal exposure to PCB has been reported to cause a variety of health effects including endocrine disruption, and immunologic, reproductive, neurologic, and behavioral deficits. In the present study, a mixture of two PCB congeners, one non-coplanar (PCB 47) and one coplanar (PCB 77), were administered to young female Sprague-Dawley rats by route of maternal dietary consumption (either 12.5 ppm or 25.0 ppm, w/w). Impact on learning and memory were examined by radial arm maze on postnatal day 24-27. After behavioral tests were completed, the rats were transcardially perfused, and brains were excised. Immunohistochemistry for ER- β ...

Mark R Wilson
Oligomeric assemblies formed from a variety of disease-associated peptides and proteins have been strongly associated with toxicity in many neurodegenerative conditions, such as Alzheimer's disease. The precise nature of the toxic agents, however, remains still to be established. We show that prefibrillar aggregates of E22G (arctic) variant of the A beta(1-42) peptide bind strongly to 1-anilinonaphthalene 8-sulfonate and that changes in this property correlate significantly with changes in its cytotoxicity. Moreover, we show that this phenomenon is common to other amyloid systems, such as wild-type A beta(1-42), the 159T variant of human lysozyme and an SH3 domain ...

Coscinium fenestratum (Gaertn.) Colebr. is traditionally used for the treatment of cancer, arthritis and diabetes mellitus. The purpose of this study was to determine the molecular mechanisms by which this plant shows beneficial effects. An 80% ethanolic extract of C. fenestratum (80ET) was separated by its polarity into dichloromethane (DCM) and aqueous fractions (WF), and the anti-proliferative effects of 80ET, DCM and WF were investigated. Berberine, one of the major components of C. fenestratum, was used as a control. The 80ET, DCM, WF and berberine showed anti-proliferative activity as assessed by cell growth assay. Subsequently, the pro-apoptotic proteins NAG-1 and ...

Gary S. Sayler
Abstract: Biomass is an abundant, domestically available source of clean energy that has the potential to greatly reduce greenhouse gas emissions. Production of biofuels from cellulosic biomass is attractive because of its low fossil energy-to-carbon ratio compared to corn and other grain-based technologies. However, biofuel production systems are not simple. They are subject to multiple factors: energy supply, economic development in rural communities, land and ecosystem protection, potential for reduction of greenhouse gas emission, and social training. This paper provides a brief overview of the environmental and economic impacts of bioenergy development. Different regions should have their own optimized portfolio ...

Evaluating The Influence Of Anthropogenic Inputs To Bottom-Up Regulation Of The Development, Survival And Emergence Rates Of Mosquito Larvae, 2009 University of Maryland - College Park
Evaluating The Influence Of Anthropogenic Inputs To Bottom-Up Regulation Of The Development, Survival And Emergence Rates Of Mosquito Larvae, David Markman
David W Markman
In aquatic and semi-aquatic ecosystems, bottom-up effects associated with resource abundance and quality play an important role in the regulation of the development, survival and emergence rates of mosquito larvae. Studying these bottom-up effects with regard to the additive impact that anthropogenic drivers may have in both urban and rural areas may be important to explain why human exposure to mosquito-borne disease is higher in urban versus rural landscapes. This study used observational methods to evaluate mosquito resident species composition across a rural to urban gradient in the Hudson Valley in New York and used experiments to test the role ...
