Global Approach And Regional Cooperation Of Black Sea Countries On The Problem Of Invasive Species, Anna Rabotnova Dec 2011

Global Approach And Regional Cooperation Of Black Sea Countries On The Problem Of Invasive Species, Anna Rabotnova

World Maritime University Dissertations

The productivity of water ecosystems plays a significant role in the development of human society. People delimitate oceans and the seas, however, ocean creatures are not familiar with those boundaries exist for them. They freely “travel” all over the world in and on ships, invade new ecosystems and harm them. Invasive alien species are now globally recognized as one of the biggest problems in shipping, which impacts environment, social economics and human health. Due to the international nature of shipping, it is positively to eliminate the problem of invasive species, but only to find the most efficient ways of controlling …

Quantification Of The Impacts Of Water Hyacinth On Riparian Communities In Cameroon And Assessment Of An Appropriate Method Of Control : The Case Of The Wouri River Basin, Jenette Tifuh. Mujingni Epse Cho

World Maritime University Dissertations

Some plants, when transported to non-endemic areas undergo reproduction and rapid growth and will out-compete native plants and become weeds. These weeds then become troublesome giving rise to socioeconomic and environmental impacts. Water hyacinth (Eicchornia crassipes), one of such weeds is often considered the world’s worst invasive aquatic species of weed, indigenous to the Amazon Basin of South America and has spread over the years to various areas in Africa and Asia. This dissertation analyses the problem of water hyacinth infestation in the Wouri River Basin, done through the quantification of its socio-economic and environmental impacts on riparian communities. It …


Agriculture In Sub-Saharan Africa, Troy M. Null Dec 2011

Agriculture In Sub-Saharan Africa, Troy M. Null

Rollins Undergraduate Research Journal

According to the World Food Programme, with the exception of Haiti, all of the world’s countries that experienced a malnourishment rate of 35% of the population or higher last year are located in sub-Saharan Africa. Of the nearly one billion hungry people in the world, one quarter of them are of them are Africans. Why is it that they are not better-able to feed themselves (or others, for that matter) with their vast amounts of undeveloped land? The goal of this paper is to demonstrate the historical and developing influences of globalization and gender on agriculture in sub-Saharan Africa, and …

A Cultured Greigite-Producing Magnetotactic Bacterium In A Novel Group Of Sulfate-Reducing Bacteria, Christopher T. Lefèvre, Nicholas Menguy, Fernanda Abreu, Ulysses Lins, Mihály Pósfai, Tanya Prozorov, David Pignol, Richard B. Frankel, Dennis A. Bazylinski

Physics

Magnetotactic bacteria contain magnetosomes—intracellular, membrane-bounded, magnetic nanocrystals of magnetite (Fe3O4) or greigite (Fe3S4)—that cause the bacteria to swim along geomagnetic field lines. We isolated a greigite-producing magnetotactic bacterium from a brackish spring in Death Valley National Park, California, USA, strain BW-1, that is able to biomineralize greigite and magnetite depending on culture conditions. A phylogenetic comparison of BW-1 and similar uncultured greigite- and/or magnetite-producing magnetotactic bacteria from freshwater to hypersaline habitats shows that these organisms represent a previously unknown group of sulfate-reducing bacteria in the Deltaproteobacteria. Genomic analysis of BW-1 reveals …

Characteristics Of Extreme Droughts Inferred From Tree-Ring Data In The Qilian Mountains, 1700−2005, Yong Zhang, Xuemei Shao, Zhi-Yong Yin, Eryuan Liang, Qinhua Tian, Yan Xu

Environmental and Ocean Sciences: Faculty Scholarship

Severe droughts were evaluated using a tree-ring network of 12 chronologies (1700−2005) from the Qilian Mountains on the northeastern Tibetan Plateau. A total of 98 drought years, including 78 moderate, 15 severe, and 5 extreme events, were identified for the past 306 yr. Following the starting year of a drought phase, drought commonly continued for 1 to 2 yr. The spatial patterns of moisture conditions in central and eastern China corresponding to 19 major drought years during the period 1700−2000 were grouped into 3 clusters, with one particular pattern showing droughts of nation-wide impact (i.e. 1721, 1928 and 1966). Drought …


Bias Correction And Downscaling Of Climate Model Outputs Required For Impact Assessments Of Climate Change In The U.S. Northeast, Kazi F. Ahmed Dec 2011

Bias Correction And Downscaling Of Climate Model Outputs Required For Impact Assessments Of Climate Change In The U.S. Northeast, Kazi F. Ahmed

Master's Theses

Global Climate Models (GCMs) are the typical sources of future climate data required for impact assessments of climate change. However, GCM outputs are related to model-related uncertainties and involve a great deal of biases. Bias correction of model outputs is, therefore, necessary before their use in impact studies. The coarse resolution of GCM simulations is another hindrance to their direct use in fine-scale impact analysis of climate change. Although downscaling of GCM outputs can be performed by dynamical downscaling using Regional Climate Models (RCMs), it requires large computational capacity. When daily climate data from multiple GCMs are required to be …


Hydrographic Controls And Seasonal Variability On The Carbonate System In The Northern Gulf Of Alaska, Kristen L. Shake Dec 2011

Hydrographic Controls And Seasonal Variability On The Carbonate System In The Northern Gulf Of Alaska, Kristen L. Shake

Marine Biology

The Northern Gulf of Alaska (GOA) supports a dynamic and economically viable marine ecosystem. One notable potential stressor to this ecosystem is ocean acidification (OA), a byproduct of the increased uptake of anthropogenic carbon dioxide (CO₂) by the ocean. Measurements of dissolved inorganic carbon (DIC) and total alkalinity (TA) were made along the continental shelf of the northern GOA and in Prince William Sound (PWS) and used to calculate seawater pH and the saturation state of aragonite Warp). Observations showed a high degree of seasonal variability in DIC concentrations in surface and bottom waters. TA was depleted relative to DIC …

Fine Roots Of Aspen Clones In High Salt And Petroleum Hydrocarbon Pollution, Kim Yrjälä, Ivika Ostonen, Shinjini Mukherjee, Timo Sipila, Lu-Min Vaario, Pertti Pulkkinen

Aspen Bibliography

The quality of polluted soil can much be improved and the environmental risks reduced by use of phytoremediation. Harmful hydrocarbon compounds can be degraded through the activity of plant and its associated microbes. We previously showed that PAHs increase aromatic ring-cleavage gene diversity in rhizosphere of birch (Sipilä et al. 2008, Yrjälä et al. 2010a) and the rhizosphere of aspen harbors Burkholderia bacteria able to degrade aromatics (Yrjälä et al. 2010b). The results are promising for successful remediation of polluted soils with woody plants. The aim of our studies is to elucidate the response of the plant and the associated …


Macrobotanical Evidence Of Diet And Plant Use At Wolf Village (42ut273), Utah Valley, Utah., Wendy Dahle Dec 2011

Macrobotanical Evidence Of Diet And Plant Use At Wolf Village (42ut273), Utah Valley, Utah., Wendy Dahle

Theses and Dissertations

Farming played a role in the subsistence base for the Fremont culture, but there is no consensus as to how significant that role was. Maize is consistently found in Fremont sites, but evidence of wild plant use is also abundant. The use of both domesticates and foraged plants by the Fremont, combined with the diversity of the landscape and sites that were inhabited by the Fremont, contributes to the diversity of theories on Fremont subsistence. This thesis examines evidence for plant usage at Wolf Village, a Fremont site in Utah Valley. Wolf Village is ideally situated for a Fremont farming …


Characterizing The Sediment Provenance Of East Antarctica's Weak Underbelly: The Aurora And Wilkes Sub-Glacial Basins, Elizabeth L. Pierce, Trevor Williams, Tina Van De Flierdt, Sidney R. Hemming, Steven L. Goldstein, Stefanie A. Brachfeld Dec 2011

Characterizing The Sediment Provenance Of East Antarctica's Weak Underbelly: The Aurora And Wilkes Sub-Glacial Basins, Elizabeth L. Pierce, Trevor Williams, Tina Van De Flierdt, Sidney R. Hemming, Steven L. Goldstein, Stefanie A. Brachfeld

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

[1] The Wilkes and Aurora basins are large, low-lying sub-glacial basins that may cause areas of weakness in the overlying East Antarctic ice sheet. Previous work based on ice-rafted debris (IRD) provenance analyses found evidence for massive iceberg discharges from these areas during the late Miocene and Pliocene. Here we characterize the sediments shed from the inferred areas of weakness along this margin (94°E to 165°E) by measuring40Ar/39Ar ages of 292 individual detrital hornblende grains from eight marine sediment core locations off East Antarctica and Nd isotopic compositions of the bulk fine fraction from the same sediments. We further expand …


American Environmentalism And The City: An Ecosystem Services Perspective, Dorothy C. Ibes Dec 2011

American Environmentalism And The City: An Ecosystem Services Perspective, Dorothy C. Ibes

Cities and the Environment (CATE)

This study traces the evolution of eight influential American environmental organizations and their relationship with, and conceptualizations of, ‘the city’ and ‘nature.’ Guided by the ecosystem services framework, the organizations’ urban-based initiatives were analyzed to determine what types of ecosystem services they emphasized and what the implications are for cities and environmental health. Results from historical, content, and interview analyses reveal the potential of the ecosystem services framework to unite the interests and efforts of multiple stakeholders, including urbanists, ecologists, economists, and environmentalists in a way that enhances both urban quality of life and conservation efforts overall.

Using Tort Law To Understand The Causation Prong Of Standing, Luke Meier Dec 2011

Using Tort Law To Understand The Causation Prong Of Standing, Luke Meier

Fordham Law Review

Under current Supreme Court case law, a plaintiff does not have Article III standing to sue in federal court unless that plaintiff can demonstrate “causation.” The term “causation” is ubiquitous within the law. Because of the frequency with which the term appears in various legal contexts, however, the conceptual analysis associated with that term can vary. Unfortunately, the Supreme Court has never clearly established the conceptual analysis necessary for making the causation determination within standing law. Consequently, there is confusion on this question. This Article addresses that confusion by relying on causation terms and concepts fully developed within tort law. …

Ecological Revival And Sustainable Living In The Tropical Dry Evergreen Forest Of Tamil Nadu: A Measurement Of Residential Perception In Sadhana Forest, Elizabeth Collette Mcguire

Department of Environmental Studies: Undergraduate Student Theses

Since 1970, the role and function of the U.S. Environmental Protection Agency (EPA) has been to promote environmental quality and to form strategies for carrying out environmental policy1. The EPA has committed to sustainability as the next level of environmental protection. The agency states that sustainability calls for policies and strategies that meet society’s present needs without compromising the ability of future generations to meet their own needs2. Presently, society’s requirements have resulted in natural resource exploitation and population distention- projected to reach 10 billion people within two human generations3. These paired occurrences are …
