Biological Sciences Faculty Publications

Marine habitats are in decline worldwide, precipitating a strong interest in marine conservation. The use of biogeographic data to designate ecoregions has had significant impacts on terrestrial conservation efforts. However, classification of marine environments into ecoregions has only become available in the last several years, based on biogeographic data supplemented by geomorphology, ocean currents, and water temperatures. Here we use a comparative phylogeographic approach to test for concordant phylogeographic patterns in three closely related species of Tridacna giant clams across the Coral Triangle, the most biodiverse marine region in the world and one of the most threatened. Data from a …

Remittance And Migration: Impact On Technology Adoption, Natural Resource Conservation, And Household Welfare, Deborah Ann Williams Jan 2014

Remittance And Migration: Impact On Technology Adoption, Natural Resource Conservation, And Household Welfare, Deborah Ann Williams

LSU Master's Theses

Nepal is the perfect country to study all the facets of migration, sustainable agriculture and their subsequent impact on food systems. Droves of migrants are leaving rural Nepal for higher incomes to cover household daily expenses. The Government of Nepal (GON) encourages migration as a means to reduce poverty, and remittance already amounts to 25.83% of GDP, and it is expected to grow (Nepal Bastra Bank 2014, Thieme and Wyss 2005, Yang 2011). However, it is still unclear whether the mass exodus from rural areas and the growing dependence on remittance, the portion of the migrant workers' earnings sent back …

The Interaction Of Climate Change, Land Cover, And Political Representation In The Usa, Brady W. Allred, Dirac L. Twidwell, Samuel D. Fuhlendorf Jan 2014

The Interaction Of Climate Change, Land Cover, And Political Representation In The Usa, Brady W. Allred, Dirac L. Twidwell, Samuel D. Fuhlendorf

Department of Agronomy and Horticulture: Faculty Publications

The difficulties in tackling climate change are inherently complex and primarily centered on political and social values. This is evident in the United States where political divisions and polarizations are fundamental barriers to advancing national policies, which in turn hinder international agreements, mitigation, and adaptation. Within the United States, the vast majority of agricultural and natural resource lands are projected to incur significant climate departures and are represented by the Republican Party. The resources and economic sectors that will be directly affected by climate change are represented by national leadership that is unlikely to accept policies to prevent or adapt …

Usefulness Of Short Sequence Repeat Markers In Goat Genetic Diversity Studies On The Asian And African Continents, Faiz M.M.T. Marikar, Muneeb M. Mustafa Jan 2014

Usefulness Of Short Sequence Repeat Markers In Goat Genetic Diversity Studies On The Asian And African Continents, Faiz M.M.T. Marikar, Muneeb M. Mustafa

Turkish Journal of Veterinary & Animal Sciences

Goat genetic diversity studies are very important since extinction of germ plasma is increasing very rapidly. The African and Asian continents are the hotspots for indigenous animals with fewer genetic manipulations. Conservation studies using molecular markers have the capability to validate the real status of the animals. The use of molecular markers has revolutionized studies of genetic diversity. Even though a number of markers are used for these types of studies, short sequence repeats are in the forefront due to their superior features such as high variability, high mutation rate, large number, distribution throughout the genome, codominant inheritance, and neutrality …

Photo-Identification Methods Reveal Seasonal And Long-Term Site-Fidelity Of Risso’S Dolphins (Grampus Griseus) In Shallow Waters (Cardigan Bay, Wales), Marijke N. De Boer, Josephine Clark, Mardik F. Leopold, Mark P. Simmonds, Peter J.H. Reijnders

Ecology Collection

A photo-identification study on Risso’s dolphins was carried out off Bardsey Island in Wales (July to September, 1997-2007). Their local abundance was estimated using two different analytical techniques: 1) mark-recapture of well-marked dolphins using a “closed-population” model; and 2) a census technique based on the total number of iden-tified individual dolphins sighted over the study period. The mark-recapture estimates of 121 (left sides; 64 - 178, 95% CI; CV 0.24) and 145 dolphins (right sides; 78 - 213, 95% CI; CV 0.24) closely matched the census technique estimates (population size of 90 - 151). It was found that the dolphins …

The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva Nov 2013

The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva

Animal Science

Due to its vast population and general negative consensus regarding snakes, India is notorious for having more snakebite incidents than any other country. Snakes are simultaneously revered and feared in Indian religion and culture. This stigma is perpetuated through propaganda, family beliefs, and innate fears of snakes.These stigmas are more pronounced within rural areas, such as the region of Mahad within the state of Maharshtra. Envenoming is endemic in these areas, and others like them. The World Health Organization identified envenoming as one of the most neglected tropical diseases of the 21st century (Nature India, 2013). Additionally, both nonvenomous and …

A Framework To Evaluate Wildlife Feeding In Research, Wildlife Management, Tourism And Recreation, Sara Dubois, David Fraser Oct 2013

A Framework To Evaluate Wildlife Feeding In Research, Wildlife Management, Tourism And Recreation, Sara Dubois, David Fraser

Wildlife Population Management Collection

Feeding of wildlife occurs in the context of research, wildlife management, tourism and in opportunistic ways. A review of examples shows that although feeding is often motivated by good intentions, it can lead to problems of public safety and conservation and be detrimental to the welfare of the animals. Examples from British Columbia illustrate the problems (nuisance animal activity, public safety risk) and consequences (culling, translocation) that often arise from uncontrolled feeding. Three features of wildlife feeding can be distinguished: the feasibility of control, the effects on conservation and the effects on animal welfare. An evaluative framework incorporating these three …

Personhood And Cloning: Modern Applications And Ethics Of Stem Cell And Cloning Technology, Sariah Cottrell Mccarrey Jul 2013

Personhood And Cloning: Modern Applications And Ethics Of Stem Cell And Cloning Technology, Sariah Cottrell Mccarrey

Theses and Dissertations

Within many communities and religions, including the LDS community, there is some controversy surrounding the use of stem cells – particularly embryonic stem cells (ESC). Much of this controversy arises from confusion and misconceptions about what stem cells actually are, where they come from , and when life begins. The theology of the Church of Jesus Christ of Latter-day Saints has interesting implications for the last of these considerations, and it becomes less a question of “when does life begin” and more an exploration of “when does personhood begin” or “when does the spirit enter the body.” With no official …

Probiotic Bioaugmentation Of An Anti-Bd Bacteria, Janthinobacterium Lividum, On The Amphibian, Notophthalmus Viridescens: Transmission Efficacy And Persistence Of The Probiotic On The Host And Non-Target Effects Of Probiotic Addition On Ecosystem Components, Molly Bletz

Masters Theses, 2010-2019

Amphibians worldwide are threatened by the fungal disease chytridiomycosis, caused by the skin pathogen Batrachochytrium dendrobatidis. Mutualistic skin bacteria are a critical element in amphibians’ defenses against chytridiomycosis. Probiotic bioaugmentation of beneficial, anti-Bd bacteria on amphibians is a potential conservation strategies. Outdoor experimental ponds were used to investigate transmission efficacy and persistence of the anti-Bd bacteria, Janthinobacterium lividum, on the amphibian, Notophthalmus viridescens. More specifically, this research investigated whether a short-term individual bath, environmental bioaugmentation, or both are necessary to afford transmission and persistence of J. lividum on N. viridescens. Additionally, this research investigated the effectiveness of these different probiotic …

Factors Influencing Nest Site Selection By Wood Turtles (Glyptemys Insculpta) In An Altered Forest Landscape, Ellery Ruther May 2013

Factors Influencing Nest Site Selection By Wood Turtles (Glyptemys Insculpta) In An Altered Forest Landscape, Ellery Ruther

Theses & Honors Papers

There have been many studies concerning wood turtle (Glyptemys insculpta) nest site selection, including studies that evaluate nest site conditions when stream sand banks are not available. However, because of the unique landscape at our study site (high gradient, first order streams) and rapidly diminishing wood turtle populations in Virginia, I am evaluating wood turtle nest site selection. Nine physiographic and vegetative characteristics from nest, positive, negative-one and negative-two control locations were evaluated using binomial generalized linear models and then best fit models were chosen using Akaike's Information Criterion (AIC). It was found that in lieu of typical stream …

Parentage Analysis And Conservation Genetics Educational Material For The Eastern Hellbender Salamander, Cryptobranchus Alleganiensis Alleganiensis, Sarah A. Chudyk

Master's Projects

Populations of the Eastern hellbender salamander, Cryptobranchus alleganiensis alleganiensis, are declining, making this a species of special concern in New York State and under consideration for Federal Endangered Species listing. As a result of this decline, the New York State Department of Environmental Conservation and the Buffalo Zoo initiated a headstarting program with an egg mass found in the Allegheny River drainage. The juveniles being raised by the Zoo will be released back into the watershed and so understanding the genetic diversity and parentage of these hellbenders will inform the reintroduction efforts. Furthermore, in order to determine how to …

Transforming The South Carolina Botanical Garden, Amy Blackwell

All Dissertations

This dissertation addresses the question of how to transform a small to mid-sized public garden into a botanical garden capable of making a significant contribution to science. Botanical gardens have certain features that distinguish them from pleasure gardens and public parks. These include a scientific basis for collections, an emphasis on recording data on the plants in the collection, exchanging plant materials and data with other botanical gardens, and providing educational information to visitors. Gardens often have several missions, including conservation of rare and endangered species, botanical and ecological research, and involving the public through citizen science. I describe my …

“Hariyo Ban Nepalko Dhan” (“Nepal’S Wealth Is The Green Forest”): The People’S Participation In Structuring Sustainable Development Through Community Forestry, Natasha Eulberg Apr 2013

“Hariyo Ban Nepalko Dhan” (“Nepal’S Wealth Is The Green Forest”): The People’S Participation In Structuring Sustainable Development Through Community Forestry, Natasha Eulberg

Independent Study Project (ISP) Collection

Community forestry has a long history in Nepal, and despite the nationalization of the country’s forests in the mid-twentieth century, current legislation determines that rights and execution of community forest management lies largely with community forest user groups (CFUGs). This research questions to what extent CFUGs truly represent autonomous bodies with the full power and ability to manage and utilize community forests and forest resources. This research also seeks to determine the impact and distribution of CFUG operations and benefits on CFUG members, and the ways in which CFUG management practices have impacted how group members perceive and interact with …

Rating Harms To Wildlife: A Survey Showing Convergence Between Conservation And Animal Welfare Views, S. Dubois, D. Fraser Jan 2013

Rating Harms To Wildlife: A Survey Showing Convergence Between Conservation And Animal Welfare Views, S. Dubois, D. Fraser

Environment and Nature Conservation Collection

Human activities may cause conservation concerns when animal populations or ecosystems are harmed and animal welfare concerns when individuals are harmed. In general, people are concerned with one or the other, as the concepts may be regarded as separate or even at odds. An online purposive survey of 339 British Columbians explored differences between groups that varied by gender, residency, wildlife engagement level and value orientation (conservation-oriented or animal welfare-oriented), to see how they rated the level of harm to wildlife caused by different human activities. Women, urban residents, those with low wildlife engagement, and welfare-orientated participants generally scored activities …

Using Gis-Based, Regional Extent Habitat Suitability Modeling To Identify Conservation Priority Areas: A Case Study Of The Louisiana Black Bear In East Texas, Christopher E. Comer, I-Kuai Hung, Gary Calkins, Dan J. Kaminski, Nathan Garner

Faculty Publications

State and federal recovery plans mandate that priority areas for future population expansion be identified within the historical range of the Louisiana black bear (Ursus americanus luteolus). Despite the presence of potentially suitable habitat in east Texas and expanding populations in adjacent states, quantitative estimates of regional habitat suitability do not exist. We developed a regional extent habitat suitability index (HSI) model in a geographic information system (GIS) to evaluate year-round habitat requirements for black bears in the 43,530-km2 south black bear recovery zone in southeastern Texas. We measured hard and soft mast production, understory vegetation density, and tree den …

Evaluating Acropora Cervicornis Growth And Survivorship In A Line Nursery, Zachary Ostroff

HCNSO Student Theses and Dissertations

Acropora cervicornis and A. palmata were once dominant, reef-building corals of Caribbean reefs. Over the last several decades, population declines of Caribbean Acropora have been dramatic, and both species are now listed as “Threatened” under the United States Endangered Species Act. Numerous restoration efforts now utilize coral gardening techniques to cultivate these species for transplantation, in which A. cervicornis is primarily cultivated both on fixed structures and in line nurseries. This study evaluates growth and survivorship of multiple A. cervicornis genotypes grown via two line nursery techniques, and compares the efficacy of each against the conventional method of fixed nursery …
