Invasive Species And Public Investment In The Green Economy, Invasive Species Advisory Committee

National Invasive Species Council

Invasive Species and Public Investment in the Green Economy, approved by ISAC on June 24, 2010

ISSUE

Invasive species are intricately linked to the economy. Trade, travel, and transport facilitate their spread. Invasive species management requires extensive human and financial resources. The impacts of invasive species can substantially undermine economic growth and sustainable development. United States Executive Order (EO) 13112 defines invasive species as “alien [non-native] species whose introduction does or is likely to cause economic or environmental harm or harm to human health” and states that Federal agencies should …“not authorize, fund, or carry out actions that are likely …

Marine Bioinvasions And Climate Change, James T. Carlton, Sandra C. Lindstrom, Celia M. Smith, Jennifer E. Smith

National Invasive Species Council

BACKGROUND

Invasive species are second only to habitat destruction as the greatest cause of species endangerment and global biodiversity loss. Invasive species can cause severe and permanent damage to the ecosystems they invade. Consequences of invasion include competition with or predation upon native species, hybridization, carrying or supporting harmful pathogens and parasites that may affect wildlife and human health, disturbing ecosystem function through alteration of food webs and nutrient recycling rates, acting as ecosystem engineers and altering habitat structure, and degradation of the aesthetic quality of our natural resources. In many cases we may not fully know the native animals …

Creating A Habitat Suitability Index Model For Argali Sheep (Ovis Ammon), And Siberian Ibex (Capra Sibirica) In Ikh Nartin Reserve, Mongolia, Nanette Bragin

Geography and the Environment: Graduate Student Capstones

Mongolia is a country with a park system of protected areas, preserving native flora and fauna. In order to inform decision makers about the status of endangered species and park land health, two species of concern, the Argali sheep (Ovis ammon) and Siberian ibex Capra siberica) in the Ikh Nart Reserve in Mongolia were studied. A Habitat Suitability Index Model was developed to study the Argali and ibex habitat preference and discern if the reserve and core zone offer optimal habitat. A total of 57 animals were examined, creating 95% and 50% home range kernels, and minimum convex polygons. The …

Raptors On Three Rnlaf Airbases, Numbers, Strikes, Trapping And Relocation.

Bird Strike Committee-USA/Canada Joint Annual Meeting: 11th (2009)

Since gulls, pigeons, starlings, waders and corvids are the dominant bird species on NW European airfields it is not surprising that habitat management systems are aimed at reducing the numbers of these species from the runway environment. In the RNLAF this is realized by a “poor grass” regime. This is based on the idea that by bottoming out the soil the available biomass will decrease and hence the number of birds foraging on this biomass. In practice this means that the grass is mown and the clippings are removed without applying any fertilization. Neither length nor species composition of the …

Fire On The Mountain: Growth And Conflict In Colorado Ski Country, Michael W. Childers

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines the environmental, economic, and cultural conflicts over the private development of ski resorts in Colorado's National Forests between 1910 and 2000. Downhill skiing emerged as an increasingly popular winter activity during the first half of the twentieth century, particularly in western state such as Colorado. A part of the a larger outdoor recreational boom throughout the United States' during the interwar years, downhill skiing challenged the Forest Service's ability to meeting the public's growing appetite for year-round recreational opportunities. These challenges increased following World War II as the nation's growing population and affluence drew millions to their …

Characterization Of Plutonium Particles Originating From The Bomarc Accident -1960, Richard Charles Gostic

UNLV Theses, Dissertations, Professional Papers, and Capstones

Within the U.S. arsenal, 32 accidents with nuclear weapons were reported between 1950 and 1980. One of these accidents occurred at McGuire AFB in 1960. A BOMARC missile armed with a nuclear warhead caught on fire and as a result the warhead was destroyed. Sub-millimeter particles consisting of weapons grade plutonium (WGPu) produced by this accident were distributed around the site and remained in the environment for 47 years. Soil cores known to contain WGPu particles produced by this accident were obtained. The particles were localized and removed from the soil with the aid of high resolution computed tomography. The …

Transforming Space Into Place: Development, Rock Climbing, And Interpretation In Red Rock Canyon National Conservation Area, 1960-2010, Megan Sharp Weatherly

UNLV Theses, Dissertations, Professional Papers, and Capstones

Though Americans tend to view wilderness as separate from nature, environmental historians have argued that wilderness is a cultural construct more than a quantifiable geographic category. Red Rock Canyon National Conservation Area (NCA), a 195,000-acre tract located west of Las Vegas, Nevada, is one such cultural construction. Since 1960, this BLM-managed parcel has served as a local and regional expression of broader, national trends in outdoor recreation, interpretation, and development and thereby forced visitors to engage (often unknowingly) in a cultural dialogue about consumerism, technology, and identity. With information from newspapers, archival collections, oral histories, and government documents, this thesis …

Aquatic Habitat Mapping Within The Obed Wild And Scenic River For Threatened And Endangered Species Habitat Delineation, Joseph Ross Candlish

Masters Theses

There is a need to define a more efficient and accurate approach to aquatic habitat mapping. Traditional approaches have focused on intense biological/non-biological sampling and observation analysis within specific and restrained scales. Therefore, an underwater video mapping system (UVMS) has been developed in efforts to identify federally protected aquatic species’ habitats within the Obed Wild and Scenic River (OBRI). The UVMS kayak apparatus provides georeferenced video footage correlated with GPS (global positioning systems) for GIS (geographic information systems) mapping applications. Based on its fluvial and geomorphological trends, OBRI was dissected quantitatively and integrated into databases for species-specific GIS habitat queries. …

Global Warming Advocacy Science: A Cross Examination, Jason S. Johnston

All Faculty Scholarship

Legal scholarship has come to accept as true the various pronouncements of the Intergovernmental Panel on Climate Change (IPCC) and other scientists who have been active in the movement for greenhouse gas (ghg) emission reductions to combat global warming. The only criticism that legal scholars have had of the story told by this group of activist scientists – what may be called the climate establishment – is that it is too conservative in not paying enough attention to possible catastrophic harm from potentially very high temperature increases. This paper departs from such faith in the climate establishment by comparing the …

Degradation Of Chlorophenols In Swine Waste, Srilatha Gangula

Masters Theses & Specialist Projects

Naturally occurring plant derived phenols can be degraded through bacteria in swine waste. Chlorinated phenols, which are not naturally present in the environment, are toxic and generated from industrial activities as such petrochemical, pharmaceutical, plastic, rubber, pesticide, iron, steel, paper production, coal conversion, wood preserving, and cellulose bleaching. Large scale coal gasification and carbonization plants are another source of chlorinated phenols. Although not normally present in the environment, chlorinated phenols are structurally similar to many plant derived phenolics.

It is our hypothesis that bacteria located in swine wastes may also have the ability to degrade chlorinated phenols. Identifying situations (and …

Effects Of Variable Oceanographic Conditions On Forage Fish Lipid Content And Fatty Acid Composition In The Northern California Current, Marisa N. C. Litz, Richard D. Brodeur, Robert L. Emmett, Selina S. Heppell, Rosalee S. Hellberg, Linda O'Higgins, Matthew S. Morris

Food Science Faculty Articles and Research

Lipids and fatty acids (FA) were investigated in 4 species of forage fish: northern anchovy Engraulis mordax, Pacific sardine Sardinops sagax, Pacific herring Clupea pallasi, and whitebait smelt Allosmerus elongatus, for their ability to serve as biological indicators of ocean conditions in the California Current large marine ecosystem (CCLME). Samples were collected during the oceanographically contrasting years of 2005 and 2006. Upwelling was severely curtailed in the spring and early summer of 2005, leading to delayed biological productivity, whereas upwelling was relatively normal in spring 2006. Principal components analysis described 78% of the variance within the …

Assessing Invasive Plant Species As Threats In Mojave Desert Parks, Sara L. Mcpherson, Donovan J. Craig, Scott R. Abella

Graduate Research Symposium (2010 - 2017)

The invasion and persistence of exotic plant species threatens the natural features that national parks are designed to protect. For example, park managers have witnessed an increase in the frequency, extent and intensity of fires along with a reduction in native species richness and diversity. Many park managers are familiar with a suite of highly invasive plants, but lack a comprehensive and systematic way of prioritizing invasive plant species based on potential threats to the parks’ resources. We have entered into a collaborative project with the National Park Service’s Inventory and Monitoring program to develop an invasive plant early detection …

Minimun Riparian Buffer Width For Maintaining Water Quality And Habitat Along Stevens Creek, Sammi Bray

Department of Environmental Studies: Undergraduate Student Theses

ABSTRACT Riparian buffer zones are important sites of biodiversity, sediment trapping, pollutant removal, and hydrologic regulation that have significant implications for both people and wildlife. Urbanization’s influence on and need for adequate water quality increases the need for careful planning in regards to riparian areas. Wildlife are key components in the ecosystem functions of riparian zones and require consideration in peri-urban planning as well. This study reviews relevant literature to determine the recommended minimum riparian buffer width for maintaining water quality and habitat along Stevens Creek in Lincoln, Nebraska. Only sources that listed a specific purpose related to water quality …

Distribution Of Rain Gardens In Lincoln Nebraska: Are Rain Gardens More Likely To Be Built Near Bodies Of Water, Eric Voecks

Department of Environmental Studies: Undergraduate Student Theses

Abstract Rain gardens are an important tool in reducing the amount of stormwater runoff and accompanying pollutants from entering the city’s streams and lakes, and reducing their water quality. This thesis project analyzed the number of rain gardens installed through the City of Lincoln Nebraska Watershed Management’s Rain Garden Water Quality Project in distance intervals of one-eighth mile from streams and lakes. This data shows the distribution of these rain gardens in relation to streams and lakes and attempts to determine if proximity to streams and lakes is a factor in homeowners installing rain gardens. ArcGIS was used to create …

An Artesian Well System In Beaver Crossing, Nebraska- It's Development And Demise, Mary Lanik

Department of Environmental Studies: Undergraduate Student Theses

ABSTRACT

Nebraska has a veritable wealth of groundwater. The High Plains Aquifer underlies most of the state, and within its sand and gravel deposits, many interconnected aquifers provide fresh water for a variety of uses.

One of the most spectacular examples of this resource is the artesian well. Beaver Crossing, Nebraska was once home to one of the most prolific artesian systems in the state before its demise. Founded in the 1880’s, Beaver Crossing soon became known for its many artesian wells, that provided leisure activities and supported profitable business ventures such as small farming, ice production and aquiculture. Eventually …
