ANDRILL Research and Publications

Fossils provide key data sets for the interpretation of the AND-1B core. Calcareous plankton and benthos provide the basis for palaeoenvironmental interpretations of both surface and bottom waters. Calcareous fossils are rare throughout, but occurrences noted are significant. Some calcareous fossils provide potential for age control via 86Sr/87Sr, and palaeoenvironmental information may come from Mg/Ca ratios as well as oxygen and carbon isotopes. Organic-walled microfossils provide an index of reworking and transport, as well as the identifi cation of a possible in situ Pliocene assemblage of previously unknown marine palynomorphs. Diatoms are abundant in the core, with …

Bomb-Spike Dating Of A Mummified Baboon In Ludwig Cave, Namibia, Greg Hodgins, George A. Brook, Eugene Marais Jan 2007

Bomb-Spike Dating Of A Mummified Baboon In Ludwig Cave, Namibia, Greg Hodgins, George A. Brook, Eugene Marais

International Journal of Speleology

In 1982 a mummified adult female baboon was discovered on a ledge in Ludwig Cave in Namibia. A toe bone was removed for dating in July 1995. AMS radiocarbon dating of bone collagen, tendon, and skin indicates a post-modern age. Application of the atomic bomb-spike calibration curve suggests death in late 1977 and an age at death of around 19 years. Baboons roost in the cave and the mummified female, along with a mummified juvenile male discovered in 2002 and three rotting corpses discovered in 1995, were probably chased by other baboons or by leopards down a ca. 6 m …

A Test Of The Cross-Scale Resilience Model: Functional Richness In Mediterranean-Climate Ecosystems, Donald A. Wardwell, Craig R. Allen, Garry D. Peterson, Andrew J. Tyre Jan 2007

A Test Of The Cross-Scale Resilience Model: Functional Richness In Mediterranean-Climate Ecosystems, Donald A. Wardwell, Craig R. Allen, Garry D. Peterson, Andrew J. Tyre

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Ecological resilience has been proposed to be generated, in part, in the discontinuous structure of complex systems. Environmental discontinuities are reflected in discontinuous, aggregated animal body mass distributions. Diversity of functional groups within body mass aggregations (scales) and redundancy of functional groups across body mass aggregations (scales) has been proposed to increase resilience. We evaluate that proposition by analyzing mammalian and avian communities of Mediterranean-climate ecosystems. We first determined that body mass distributions for each animal community were discontinuous. We then calculated the variance in richness of function across aggregations in each community, and compared observed values with distributions created …

Local And Regional-Scale Societal Dynamics In Grizzly Bear Conservation, Douglas Andrew Clark Jan 2007

Local And Regional-Scale Societal Dynamics In Grizzly Bear Conservation, Douglas Andrew Clark

Theses and Dissertations (Comprehensive)

Conserving grizzly bear populations is a significant challenge for wildlife managers throughout North America. Much fruitful research has been conducted on the biology of grizzlies, but the human dimensions of bear management remain poorly understood. This imbalance has created conflicts between management agencies and local inhabitants that can jeopardize ecosystem management and planning programs in which grizzlies often feature as key components. Broadly, the goal of this study was to understand how and why such conflicts occur. Qualitative data analysis methods and the policy sciences' interdisciplinary problem analysis framework, along with insights from adaptive governance and co-management concepts, resilience theory, …


An Institutional Analysis Of Oil And Gas Sector Development And Environmental Management In The Yukon Territory, Jason C. May Jan 2007

An Institutional Analysis Of Oil And Gas Sector Development And Environmental Management In The Yukon Territory, Jason C. May

Theses and Dissertations (Comprehensive)

This thesis investigates the ways in which oil and gas development priorities and concern for the environment are integrated within strategic planning and management frameworks, and how associated conflict is addressed, in a case study of the Yukon. Because substantial ground-based oil and gas activity is yet to occur in the territory, a thorough understanding of the institutions and institutional arrangements set to govern future oil and gas development is a valuable tool for gauging the capacity to integrate these priorities. Therefore, this thesis employs the Institutional Analysis and Development (IAD) framework to analyze the legislation, regulations, policies, and institutions …


An Analysis Of Social Aspects Of Forest Stewardship Council Forest Certification In Three Ontario Case Studies, Melanie Venne Jan 2007

An Analysis Of Social Aspects Of Forest Stewardship Council Forest Certification In Three Ontario Case Studies, Melanie Venne

Theses and Dissertations (Comprehensive)

Forest certification is a market-based tool whereby forest management is evaluated against a set of standards that consider environmental, economic and social elements of sustainability. Certificiation is therefore a means of providing customers with the assurance that forest products are originating from sustainability managed forests. It grew out of the ideal of sustainable forest management (SFM) and pulls from its predecessor the concept of multiple dimensions of sustainability. The focus of this project was the international forest certification scheme Forest Stewardship Council (FSC).

A comparative case study approach was used to examine the social implications of certification in three FSC …


Nutrient Concentrations At Baseflow Conditions In The Upper White River Basin, Southwest Missouri And Northwest Arkansas, Gopala G. Borchelt Jan 2007

Nutrient Concentrations At Baseflow Conditions In The Upper White River Basin, Southwest Missouri And Northwest Arkansas, Gopala G. Borchelt

Graduate Theses/Dissertations

The Upper White River Basin (UWRB) is becoming increasingly vulnerable to water quality degradation from urban/population growth and increased agricultural production. This study examines the relationships among nutrient levels, water chemistry and watershed characteristics of 19 watersheds in the UWRB. Water samples were collected during baseflow conditions each month for one year at USGS continuous-flow gage stations. Watershed characteristics evaluated were land use, geology, drainage area, flow discharge, and wastewater treatment plant discharge (WTP). Measured chemical water quality indicators include total nitrogen (TN), total phosphorus (TP), specific conductivity, turbidity, pH and dissolved oxygen. Rapidly expanding urban areas are associated with …


Racial Inequality In The Distribution Of Hazardous Waste: A National-Level Reassessment, Paul Mohai, Robin Saha Jan 2007

Racial Inequality In The Distribution Of Hazardous Waste: A National-Level Reassessment, Paul Mohai, Robin Saha

Environmental Studies Faculty Publications

National-level studies examining racial disparities around hazardous waste treatment, storage, and disposal facilities have been very influential in defining the academic and political debates about the existence and importance of "environmental injustice." However, these studies tend to employ methods that fail to adequately control for proximity between environmentally hazardous sites and nearby residential populations. By using GIS and applying methods increasingly used in environmental inequality research that better control for proximity, we conduct a comprehensive reassessment of racial inequality in the distribution of the nation 's hazardous waste facilities. We compare the magnitude of racial disparities found with those of …

Model Estimation Of Land-Use Effects On Water Levels Of Northern Prairie Wetlands, Richard A. Voldseth, W.Carter Johnson, Tagir Gilmanov, Glenn R. Guntenspergen, Bruce V. Millett

Natural Resource Management Faculty Publications

Wetlands of the Prairie Pothole Region exist in a matrix of grassland dominated by intensive pastoral and cultivation agriculture. Recent conservation management has emphasized the conversion of cultivated farmland and degraded pastures to intact grassland to improve upland nesting habitat. The consequences of changes in land-use cover that alter watershed processes have not been evaluated relative to their effect on the water budgets and vegetation dynamics of associated wetlands. We simulated the effect of upland agricultural practices on the water budget and vegetation of a semipermanent prairie wetland by modifying a previously published mathematical model (WETSIM). Watershed cover/landuse practices were …


Environmental Factors Influencing The Siting Of Temporary Housing In Orleans Parish, Philip J. Chandler Jan 2007

Environmental Factors Influencing The Siting Of Temporary Housing In Orleans Parish, Philip J. Chandler

LSU Master's Theses

The disaster in New Orleans due to Hurricane Katrina showcased the city's many environmental problems. The industrial history of the city, subsidence of the city causing it to be below sea-level, and the fact that the city is protected by levees and pumps were critical elements of the disaster and played a large role in the emergency response. The disaster led to an enormous emergency response by many entities, but the Federal Emergency Management Agency (FEMA) has the lead in these actions. In response to the large number of homes being flooded and unlivable in Orleans Parish, FEMA implemented its …

Hurricane Modeling In Gis: An Investigation Of Threshold Storm Events Affecting Special Medical Needs Populations In Coastal Louisiana, Kathryn Emily Streva

LSU Master's Theses

Recent hurricane events in coastal Louisiana have emphasized the severe vulnerability of medical special needs (MSN) patients during flood disasters. MSN populations may be comprised of hospital, nursing home or hospice patients; the physically or mentally disabled; medically-dependent individuals requiring life-sustaining equipment or medicines; and frail elderly. Over 150 hospital and nursing home fatalities resulted from Hurricane Katrina in New Orleans. More than four hundred elderly over the age of seventy perished. Chronic diseases and mental health illness were among the top conditions reported in field hospitals, emergency rooms and shelters immediately following the storm. Louisiana MSN facilities and residences …

Concept Analysis In Web Documents, Rajesh Singh Jan 2007

Concept Analysis In Web Documents, Rajesh Singh

Master's Projects

A Keyword within a text/web document represents some human thought. The interaction of keywords leads to narrowing of scope of human thought by forming a more precise semantic entity called concepts. Analyzing a set of document not only requires analysis of the keywords within those documents but also their interactions within a document. In this new approach a set of documents can be analyzed where by the interactions of its keywords is also considered in finding the important concepts. These concepts can be used to cluster them into smaller subsets such that documents in each cluster will be semantically similar.


Biogeography And The Cambrian Radiation Of Arachnomorph Arthropods, Jonathan R. Hendricks, Bruce S. Lieberman Jan 2007

Biogeography And The Cambrian Radiation Of Arachnomorph Arthropods, Jonathan R. Hendricks, Bruce S. Lieberman

Faculty Publications

Biogeographic patterns in primarily Cambrian arachnomorph taxa are investigated using a recently constructed phylogenetic hypothesis in order to explore the biogeographic context of the Cambrian radiation. A modified version of Brooks Parsimony Analysis is employed to elucidate patterns of vicariance and geodispersal in taxa from six regions (Laurentia, Baltica, Siberia, Australia, Africa and China). Well resolved vicariance and geodispersal trees are very similar and reconstruct Laurentia and China as sister areas. This close area relationship between Laurentia and China provides extensive evidence for congruent vicariance and range expansion in Cambrian arachnomorphs, while data from trilobites do not show this pattern. …


Shelf-Margin Delta Morphology As A Paleo Sea Level Indicator: Implications On Late Quaternary Relative Sea-Level Changes In The Northeast Gulf Of Mexico, Swati Ghoshal Jan 2007

Shelf-Margin Delta Morphology As A Paleo Sea Level Indicator: Implications On Late Quaternary Relative Sea-Level Changes In The Northeast Gulf Of Mexico, Swati Ghoshal

LSU Doctoral Dissertations

A new technique to determine relative sea level history at siliciclastic settings is proposed in this dissertation. The clinoform break (defined as the topset-foreset transition point) of the modern Mississippi River Delta shows a direct relationship with sea level elevation. The analysis of Holocene lobes 8 and 9 belonging to the St. Bernard delta complex of the Mississippi Delta suggests that delta clinoforms can be significantly modified by post-abandonment processes, and hence a detailed stratigraphic evaluation is necessary to determine whether the clinoform geometry is a result of wave erosion or any other post-abandonment processes. The strategy was tested on …


Modeling The Dynamics Of Tritrophic Population Interactions, Andrew Paul Gutierrez, Johann Baumgärtner Jan 2007

Modeling The Dynamics Of Tritrophic Population Interactions, Andrew Paul Gutierrez, Johann Baumgärtner

All Peer-Reviewed Publications

Introduction Increasingly, population modeling and systems analysis are being used to examine the complex issues that are at the heart of CP/IPM (crop production and integrated pest management) and biological control. The design of economically sound and sustainable crop management strategies requires a thorough understanding of the whole production system including arthropod pests, pathogens, and weeds. More than three decades ago, Huffaker and Croft (1976) stressed the need to rely on systems analysis and interdisciplinary collaboration to accomplish this task. Soon the question arose as to how mathematical techniques employed in the analysis of physical systems could be adapted to …


Speleothems As Indicators Of Wet And Dry Periods, Ian John Fairchild, Emily Anne Mcmillan Jan 2007

Speleothems As Indicators Of Wet And Dry Periods, Ian John Fairchild, Emily Anne Mcmillan

International Journal of Speleology

Calcareous speleothems provide a record of dripwater composition which in turn is a function of climatic conditions. The historical focus of speleothem palaeoclimate studies has been on the derivation of palaeotemperatures through oxygen isotope studies. However, it is now realized that water availability is a more generally important control on their characteristics. Growth rate and growth morphology in principle should give rise to recognizable changes at low flow. However, accidental plumbing effects during aquifer evolution, can also lead to variations in water supply and it is not easy to distinguish these effects. In areas where there is a strong amount …


Gis-Based Integration Of Swat And Remm For Estimating Water Quality Benefits Of Riparian Buffers In Agricultural Watersheds, Y. Liu, Wanhong Yang, Xixi Wang Jan 2007

Gis-Based Integration Of Swat And Remm For Estimating Water Quality Benefits Of Riparian Buffers In Agricultural Watersheds, Y. Liu, Wanhong Yang, Xixi Wang

Civil & Environmental Engineering Faculty Publications

The Soil and Water Assessment Tool (SWAT) is a process-based, watershed-scale model with a hydrologic response unit (HRU) as the basic computation element, which makes it difficult to accurately represent riparian buffers using their physical parameters (e.g., vegetation structure). On the other hand, the field-scale Riparian Ecosystem Management Model (REMM) provides the opportunity to consider details of hydrologic processes within a riparian buffer zone. However, the runoff and its associated constituents from the upland area that is hydraulically connected to the riparian buffer zone must be provided as inputs into REMM. The rationale proposed here is that the integration of …

The Polygenetic Caves Of Cuatro Ciénegas (Coahuila, Mexico): Morphology And Speleogenesis, Leonardo Piccini, Paolo Forti, Italo Giulivo, Marco Mecchia Jan 2007

The Polygenetic Caves Of Cuatro Ciénegas (Coahuila, Mexico): Morphology And Speleogenesis, Leonardo Piccini, Paolo Forti, Italo Giulivo, Marco Mecchia

International Journal of Speleology

The Cuatro Ciénegas area is renown worldwide for its thermal springs, which feed a unique ecosystem consisting of many pools, lakes and marshes. The pools also represent a very important water resource in a region characterized by scarce rainfalls. Field investigation has emphasized the role of karst in the hydrogeology of the area. Only few and restricted forms of surface karst are represented; caves are mainly relics of old speleogenetic phases of thermal and bathyphreatic water flow.
