Fussy Feeders: Phyllosoma Larvae Of The Western Rocklobster (Panulirus Cygnus) Demonstrate Prey Preference, M I Saunders, P A Thompson, A G Jeffs, Christin Sawstrom, N Sachlikidis, L E Beckley, A M Waite

Research outputs 2012

The Western Rocklobster (Panulirus cygnus) is the most valuable single species fishery in Australia and the largest single country spiny lobster fishery in the world. In recent years a well-known relationship between oceanographic conditions and lobster recruitment has become uncoupled, with significantly lower recruitment than expected, generating interest in the factors influencing survival and development of the planktonic larval stages. The nutritional requirements and wild prey of the planktotrophic larval stage (phyllosoma) of P. cygnus were previously unknown, hampering both management and aquaculture efforts for this species. Ship-board feeding trials of wild-caught mid-late stage P. cygnus phyllosoma in the eastern …

Patterns Of Seasonal Variation In Diet, Abundance, And Movement Of The Scarlet Macaw (Ara Macao) In Southern Belize, Mark Stephen Mcreynolds

Antioch University Dissertations & Theses

This study was conducted in 2008 and 2009 to determine if Scarlet Macaws (Ara macao), in subtropical southern Belize, Central America, are seasonal and elevational migrants and if their movement is influenced by seasonally abundant food. Reports from southern Belize indicated strongly seasonal sightings of macaws (N ≈ 200) in two separate areas of considerable difference in elevation. I monitored plant phenology plots (2 m x 500 m) in low (N = 6) and high (N = 6) elevation areas for a year to compare fruit abundance with macaw sightings in point counts on the plots and nearby. My point …

Effect Of Air Pollution On Daily Morbidity In Karachi, Pakistan, Haider Khwaja, Zafar Fatmi, Daniel Malashock, Zafar Aminov, Ambreen Kazi, Azhar Siddique, Jahanzeb Qureshi Qureshi, David Carpenter

Community Health Sciences

Levels of daily particulates (PM2.5) were monitored at two sites in Karachi, Pakistan. One site (Korangi) is an industrial and residential neighborhood, while the other (Tibet Center) is a commercial and residential area near a major highway. Monitoring was done daily for a period of six weeks during spring, summer, fall and winter. Particulate levels were extraordinarily high, with the great majority of days falling into the “unhealthy for sensitive groups” or “very unhealthy” categories. The mean PM2.5 levels in Karachi exceeded the WHO’s 24 h air quality guideline almost every day and often by a factor of greater than …

Database Of Diazotrophs In Global Ocean: Abundance, Biomass, And Nitrogen Fixation Rates, Y. W. Luo, S. C. Doney, L. A. Anderson, M. Benavides, I. Berman-Frank, A. Bode, S. Bonnet, K. H. Boström, D. Böttjer, D. G. Capone, M. R. Mulholland

OES Faculty Publications

Marine N₂ fixing microorganisms, termed di-azotrophs, are a key functional group in marine pelagic ecosystems. The biological fixation of dinitrogen (N₂) to bioavailable nitrogen provides an important new source of nitrogen for pelagic marine ecosystems and influences primary productivity and organic matter export to the deep ocean. As one of a series of efforts to collect biomass and rates specific to different phytoplankton functional groups, we have constructed a database on diazotrophic organisms in the global pelagic upper ocean by compiling about 12 000 direct field measurements of cyanobacterial diazotroph abundances (based on microscopic cell counts or …

Assessing Urban Environmental Management Practice With A Scalar Approach: The Case Of Shanghai, Wei Tu

Earth, Environment & Sustainability: Faculty Publications

Shanghai’s urban environmental management in the past three decades has been focused primarily on the environmental problems at the intra-urban level. While this ‘end of pipe’ approach greatly mitigated domestic and industrial pollution, progresses were much slower in dealing with environmental impacts both at a smaller (i.e., those related to people’s daily activities) scale and at a larger (i.e., those related to inter-urban/regional or global issues) scale. Urban environmental management policies in Shanghai and China should prioritize and address urban environmental impacts at continuous geographic scales to achieve long-term ‘triple bottom line’ sustainability.

Determining The Feasibility Of Universal Access To Bus Transportation For Illinois Wesleyan University Students, Liz Kuehn '13

Outstanding Senior Seminar Papers

In a car-based society, transportation has both environmental and economic implications. However, public transportation, and programs like Universal Access that promote public transportation by providing ‘fare free’ access to specific groups in the community, can offer low cost, sustainable alternatives to car-based transportation. The basic concept behind Universal Access is that a community group contracts with the local public transit system to provide unlimited access to public transportation for individuals within the group at a negotiated cost to the group (Toor et. al 2004). The purpose of this study is to determine the feasibility of creating a Universal Access program …

Solar Energy Development On The Federal Public Lands: Environmental Trade-Offs On The Road To A Lower Carbon Future, Robert L. Glicksman

San Diego Journal of Climate & Energy Law

The federal government has endorsed more extensive use of the federal public lands for the production of solar power, both to reduce the greenhouse gas emissions that contribute to climate change and to bolster the security of domestic energy supplies. Spurred by grant money made available under the American Recovery and Reinvestment Act of 2009, the Bureau of Land Management (BLM) in 2010 approved nine utility-scale solar projects on public lands in California and Nevada. These projects were designed to avoid adversely affecting the habitats of endangered and threatened species that frequent the desert southwest and cultural resources important to …

The Effect Of Compost Amendment On Ammonia-Oxidizing Microbial Community Structure In An Agricultural Soil, Gregory S. Klinger

Graduate Theses, Dissertations, and Problem Reports (ETD)

The effect of compost amendment on nitrification rates and ammonia-oxidizing microorganisms in an agricultural soil was examined. Four different rates from 11.2 to 89.6 Mg compost ha-1 of partially composted dairy manure was applied annually from 2000 to 2003 and again in 2005 to 32 plots on a Dormont silt loam that was shifted from long term pasture to crop cultivation. An additional 8 plots were not amended with compost and served as negative controls. Except for lime in the initial year of the experiment, no other fertilizer was used on these plots. Soil physical, chemical, and biochemical measurements were …

Project Risk And Appeals In U.S. Forest Service Planning, Marc J. Stern, S. Andrew Predmore, Wayde C. Morse, David N. Seesholtz

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

The National Environmental Policy Act (NEPA) requires U.S. Forest Service planning processes to be conducted by interdisciplinary teams of resource specialists to analyze and disclose the likely environmental impacts of proposed natural resource management actions on Forest Service lands. Multiple challenges associated with these processes have been a source of frustration for the agency. One of these challenges involves administrative appeals through which public entities can challenge a Forest Service decision following a NEPA process. These appeals instigate an internal review process and can result in an affirmation of the Forest Service decision, a reversal of that decision, or additional …

Constructing Wilderness: The Nexus Of Preservation And Ocean-Space In The United States, Ryan Orgera

LSU Doctoral Dissertations

The ocean has long played a minor role in human geography; imagining it as natural space rather than an extractive space even less significant. This dissertation explores the most revered kind of American nature preservation: wilderness. Despite the millions of acres set aside as wilderness in the United States, no such designation exists for ocean-space as a discrete entity. Through the analysis of congressional hearings, bills, resolutions, public laws, and maps, this dissertation uncovers the complex constructs of the production of legal wilderness. Furthermore, it uncovers a novel vein of inquiry, that of the ocean as a preserved natural space. …

Managing Climate Change Through Biological Sequestration: Open Space Law Redux, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

Climate change management involves strategies that mitigate its causes and adapt human communities to its consequences. This article describes a legal strategy that does both: a national biological sequestration policy. This policy will increase the amount of carbon dioxide emissions that biological sequestration currently removes from the atmosphere and will enable human settlements to adapt to the harsh effects of a changing climate, while realizing a number of other objectives that preserved open space preservation achieves. The article sketches the influences of international and national climate change law, which largely ignore the benefits of biological sequestration on privately owned land …

Land Use For Energy Conservation And Sustainable Development: A New Path Toward Climate Change Mitigation, John R. Nolon

Elisabeth Haub School of Law Faculty Publications

Land use tools and techniques have impressive potential to reduce energy consumption, improve the economy, and mitigate climate change. This article explores the little understood influence of local land use decision-making on energy conservation and sustainable development and how it can mitigate climate change if properly assisted by the federal and state governments. The construction and use of buildings combined with extensive vehicular travel throughout the nation’s human settlements consume large amounts of energy, and much of that consumption is highly inefficient. By enforcing and enhancing energy codes, encouraging the use of combined heat and power and district energy systems, …

An Inquiry Into Eco-Labeling: The Promise Of Predator Friendly Certification (Pfc), Melissa Ellen Katherine Early

Graduate Student Theses, Dissertations, & Professional Papers

Agricultural landscapes play key roles in preserving biodiversity through habitat protection while providing ecosystem services necessary for rural livelihoods. There is a small, but growing movement among agricultural producers to live with nature rather than to dominate nature. Within this larger agriculture movement are efforts to live with predators rather than eliminating them through lethal means. This is reflective of the changing conversation around predators in the New West. Means of co-existence include livestock guardian animals, electric fencing, fladry, range rider patrols, rotational grazing, and lights etc. One grassroots effort in this area is Predator Friendly Certification (PFC). PFC is …

Exploring Visitor Experiences Along The Going-To-The-Sun Corridor Of Glacier National Park, Elena Nikolaeva

Graduate Student Theses, Dissertations, & Professional Papers

Visitor use on the Going-to-the-Sun Road (GTSR) corridor is one of the most critical issues that Glacier National Park faces. According to the park’s General Management Plan, it should be addressed to safeguard the quality of park resources and the visitor experiences. 80% of park visitors travel along at least some part of the road, which is the primary park experience and one of the most spectacular highlights of the park. The road was built in early 1930, and now brings almost 2 million visitors annually into the heart of Glacier NP. Increased number of cars on this narrow historic …

Artification In Natural History Museums, Kaisa Mäki-Petäjä

Contemporary Aesthetics (Journal Archive)

Natural history exhibitions have changed considerably over recent decades concurring with a rise of a general movement of aestheticization in the Western culture. This usually results from an attempt to make the exhibitions more appealing to provide the public numerous ways of enjoying themselves, but they are also used to communicate information, especially of an ethical and affective kind. In this paper I will consider the effects of a particular kind of aestheticization, namely artification, of these kinds of exhibitions. Artification, i.e, the process of regarding non-art objects as art, appears to be in conflict with the science-based purposes of …

Dinner Conversation, Alyssa A. Wood

Harriet L Wilkes Honors College Theses 2010 - 2019

This study explores the perceived elitism within both the environmentalist community and general public in regards to "environmental diets" such as : vegetarianism, veganism, locavore-ism, and ethical omnivory. I explore these diets and potential expressions of elitism within the framework developed by Morrison and Dunlap in their discussion of environmental elitism. Examples come from published sources as well as personal anecdotes. Through this study, I suggest that this perceived elitism is actually not elitism per se, but a very thin line of tension between describing the ideal food systems aside the current state of food inequity and industrial agriculture. Simply, …

Wolf Perception And Policy In The United States, Sarah. Rouse

Harriet L Wilkes Honors College Theses 2010 - 2019

Throughout the course of North American history, wolves have been persecuted with a vengeance. Negative wolf perceptions have in the past created and continue to create controversial policies and views towards wolves. While most of these attitudes are geared towards gray wolves, as gray wolves are the most common and prominent, unfavorable perceptions have also extended to the less well-known red wolf. This study compares two red wolf reintroduction programs, one in the Tennessee-Kentucky area and the other in North Carolina, as well as the Yellowstone Gray Wolf Reintroduction program. After analyzing these three programs, it can be concluded that …

Pay-To-Pave", Melinda. Florscher

Harriet L Wilkes Honors College Theses 2010 - 2019

This study assesses the philosophical underpinnings of endangered species protections focused on gopher tortoises in Florida. From 1993-2007, gopher tortoises (Gopherus polyphemus) were listed in Florida as a species of special concern. Land developers wanting to build on their habitats could apply for an incidental take permit, paying a fee that allowed tortoises to be 'entombed' in their burrows to die a slow death. In 2007, when gopher tortoise status was up-losted to 'threatened', a new policy ended the incidental take permit program. This study compares policy guidelines of the 1991 and 2007 gopher tortoise management plans and explores cases …

Employing Cultural Landscapes In Community Preservation, Rachel Blythe

Harriet L Wilkes Honors College Theses 2010 - 2019

Druid Hills is a historic suburb of Atlanta, Georgia, that was initially designed by landscape architech Frederick Law Olmsted in 1893. As one of Atlanta's first suburbs, Druid Hills has faced the consequences of sprawl, particularly in the 1980s when the Georgia Department of Transportation proposed construction of the Presidential Parkway, an expressway that would have cut through the middle of the neighborhood. In opposition to the expressway, members of the surrounding communities organized Citizens Against Unnecessary Thoroughfares In Older Neighborhoods (CAUTION). The strategic rhetoric of CAUTION's campaign emphasized Druid Hills' significance as "Olmsted's Vision of Atlanta," yet their use …

Analyses Of Surface Wave Seismic Data And Supplemental Borehole And Electrical Resistivity Tomography Control, Mengxing Li

Masters Theses

"Multichannel analyses of surface wave (MASW) data and electrical resistivity tomography (ERT) control were acquired at two test sites in central Missouri. Limestone bedrock existed at both test sites at variable depths. The ground surface at both test sites was relatively flat.

The primary objective was to map the variable depth to the top of the rock based on shear-wave velocity contrasts. ERT data and borehole control were acquired at each site in order to constrain the interpretation of the MASW data.

The MASW method proved to be more effective than the ERT method in terms of mapping soil layers …
