Grassland Songbirds In A Dynamic Management Landscape: Behavioral Responses And Management Strategies, Noah G. Perlut, Allan M. Strong, Therese M. Donovan, Neil J. Buckley

Environmental Studies Faculty Publications

In recent decades, earlier and more frequent harvests of agricultural grasslands have been implicated as a major cause of population declines in grassland songbirds. From 2002 to 2005, in the Champlain Valley of Vermont and New York, USA, we studied the reproductive success of Savannah Sparrows (Passerculus sandwichensis) and Bobolinks (Dolichonyx oryzivorus) on four grassland treatments: (1) early-hayed fields cut before 11 June and again in early- to mid-July; (2) middle-hayed fields cut once between 21 June and 10 July; (3) late-hayed fields cut after 1 August; and (4) rotationally grazed pastures. Both the number of …

Evaluating Diet Composition Of Pronghorn In Wind Cave National Park, South Dakota, Christopher N. Jacques, Jaret D. Sievers, Jonathan A. Jenks, Chad L. Sexton, Daniel E. Roddy

The Prairie Naturalist

The pronghorn (Antilocapra americana) was reintroduced into Wind Cave National Park (WCNP), South Dakota, in 1914, and thus, has inhabited the Park for nearly a century. During the 1990's, a decline in the population raised concern for the continued existence of pronghorn inside WCNP; an investigation into the observed decline was initiated. Primary objectives of our study were to evaluate diet composition and forage selection by pronghorn in WCNP. Microhistological analysis was conducted on 58 fecal samples collected opportunistically from pronghorn during 2002. Blue grama (Bouteloua gracilis), common juniper (Juniperus communis), and northern bedstraw …

Synthesis And Characterization Of Inosamines, Sing Raj Gurung

Masters Theses

This project is concerned with the preparation of scyllo-inosarnine hydrochloride 6, a biologically active compound, which bears six successive stereogenic centers. The synthesis of this compound would help elucidate the involvement of inosamines in biological nitrogen fixation. myo-Inositol served as the starting material to synthesize target compound 6. Regioselective protection and deprotection of myo-inositol provided azide 43 as key intermediate. In the final steps deprotection of five benzyl groups and reduction of azido group was achieved by catalytic hydrogenation. scyllo-Inosamine hydrochloride 6 was fully characterized by m.p., ¹H NMR, ¹³C NMR, IR, EA and via …

Nesting Success Of Grassland And Savanna Birds On Reclaimed Surface Coal Mines Of The Midwestern United States, Edward W. Galligan, Travis L. Devault, Steven L. Lima

United States Department of Agriculture Wildlife Services: Staff Publications

Reclaimed surface coal mines in southwestern Indiana support many grassland and shrub/ savanna bird species of conservation concern. We examined the nesting success of birds on these reclaimed mines to assess whether such ‘‘unnatural’’ places represent productive breeding habitats for such species. We established eight study sites on two large, grassland-dominated mines in southwestern Indiana and classified them into three categories (open grassland, shrub/savanna, and a mixture of grassland and shrub/savanna) based on broad vegetation and landscape characteristics. During the 1999 and 2000 breeding seasons, we found and monitored 911 nests of 31 species. Daily nest survival for the most …

Seasonal Dietary Composition Of The Eastern Coyote (Canis Latrans) On The Berry College Campus In Northwestern Georgia, Kathleen Melissa Owens

Masters Theses and Doctoral Dissertations

Coyotes (Canis latrans) have progressively colonized eastern North America following wolf extirpation and the clearing of forested landscapes. The coyote has expanded its geographic range into Georgia during the past 50 years, and its impact as the top predator is potentially influencing community dynamics via competition and/or predation. Few studies have examined coyote food habits in the southeastern United States. Our objective was to determine prey items consumed by free-ranging coyotes living on Berry College lands in northwestern Georgia. One hundred and twenty-seven coyote scats were collected from May 2005 through August 2006 along seven major service roads that transected …

Changes In Land Cover And Soil Conditions For The Yabelo District Of The Borana Plateau, 1973-2003, D. Layne Coppock, Sintayehu Mesele, Heluf Gebrekidan, Lemma Gizachew

Environment and Society Faculty Publications

It has been proposed that the Borana Plateau has markedly changed in terms of land cover and land use in recent decades, but no hard data have been available to critically assess this claim. In addition, systematic analysis of soil properties has been limited. Research was designed to measure changes in land cover/land use over 30 years in the 400-km2 Yabelo District of southern Ethiopia using three satellite images taken at an average interval of 15 years. Samples were also collected to assess variation in the physical and chemical properties of dominant soils. Results indicated that Yabelo District has indeed …

From Herd Diversification To Livelihood Diversification As A Response To Poverty: The Case Of The Waso Boran Of Northern Kenya, D. Layne Coppock, Abdullahi D. Jillo, Abdillahi A. Aboud

Environment and Society Faculty Publications

The Waso Boran of northern Kenya used to have large, mobile, and diverse herds of livestock that exploited equally large and diverse rangelands. Forty years of human population growth, drought, environmental change, and lack of relevant policies have altered this situation, however, with the majority of Waso Boran today being livestock poor and engaged in a variety of non-pastoral activities to diversify their livelihoods. One-third of 540 households we surveyed in Isiolo District now have ten head of cattle or less, and a larger census suggests that only 15 percent of households can currently be categorized as mobile pastoralists. The …

Collective Action By Women’S Groups To Combat Drought And Poverty In Northern Kenya, D. Layne Coppock, Solomon Desta, Getachew Gebru, Adan Wako, Ibrahim Aden, Chachu Tadecha, Seyoum Tezera

Environment and Society Faculty Publications

Collective action can be an effective means of local development and risk reduction among rural people, but few examples have been documented in pastoral areas. We conducted extensive interviews for 16 women’s groups residing in northern Kenya. Our objectives were to understand how groups were formed, governed, and sustained and what activities they have pursued. The groups we interviewed were 10 years old, on average. Charter memberships averaged about 24 women, 20 of whom were illiterate. Half of the groups formed after facilitation by a development partner and half formed spontaneously. Groups are governed under detailed constitutional frameworks with elected …

Community Perceptions Concerning Key Ecological Resources At Risk In Baringo District, Kenya, D. Layne Coppock, Mark N. Mutinda, Abdillahi A. Aboud

Environment and Society Faculty Publications

Key ecological resources in arid and semi-arid lands are often characterized by small patches of seasonal grazing and important water points that lend critical support to entire production systems. When key resources are degraded or lost, production systems can be badly compromised. The Baringo District of north-central Kenya is well known for enduring decades of environmental degradation and food relief. As an initial part of an effort to map and characterize key ecological resources at risk in Baringo, we interviewed 136 resident leaders from pastoral and agro-pastoral areas. We asked them to identify and rank their most vulnerable ecological resources, …

Public Engagement To Prioritize The Pastoral Research Agenda At The Pastoral And Agro-Pastoral Research Center Of Oari In Ethiopia, D. Layne Coppock, Getachew Gebru, Lemma Gizachew, Sintayehu Mesele, Mohammed Hassena, Solomon Desta

Environment and Society Faculty Publications

The Oromia Agricultural Research Institute (OARI) has a mandate to conduct agricultural and livestock research throughout the Regional State of Oromia in Ethiopia. OARI has recently opened a facility near Yabello town on the Borana Plateau called the Pastoral and Agro-Pastoral Research Center. A meeting was held in August 2006 at Yabello that involved representatives from pastoral communities, the private sector, government, and non-governmental organizations. The aim was to engage stakeholders in a process of problem prioritization and set the stage to create new partnerships to better address pressing problems. The final priorities included: addressing a general decline in forage …

Regulation Of A Dna-Compacting Plastid Nucleoid Protein, Steven William Adamson

Dissertations

DCP68, a DNA-compacting nucleoid protein, was further characterized in order to understand how plastid nucleoid proteins affect the structure and function of chloroplast DNA. Previously, DCP68 was identified as ferredoxin: sulfite reductase, an enzyme that participates in reductive sulfur assimilation and inhibits chloroplast DNA replication and transcription in vitro [1, 2]. In this study, the portion of SiR that was found to be present in soluble and plastid nucleoid-enriched fractions indicated that most SiR was stromal in Arabidopsis and soybean plants. Although SiR was detected in Arabidopsis chloroplast nucleoid-enriched fractions, the study of nucleoid dynamics proved to be difficult due …

New Options For Extending Grazing, Edward N. Ballard

Kentucky Grazing Conference

Feed costs represent the major cost in most livestock production systems. A recently completed analysis of 225 Standardized Performance Analysis (SPA) Beef Cow Records on herds in Illinois and Iowa showed that feed cost was the overriding factor determining profitability, explaining over 57 percent of the herd-to-herd variation.

One Reserve, Three Primates: Applying A Holistic Approach To Understand The Interconnections Among Ring-Tailed Lemurs (Lemur Catta), Verreaux's Sifaka (Propithecus Verreauxi), And Humans (Homo Sapiens) At Beza Mahafaly Special Reserve, Madagascar, James E. Loudon, Michelle L. Sauther, Krista D. Fish, Mandala Hunter-Ishikawa, Youssouf Jacky Ibrahim

Ecological and Environmental Anthropology (University of Georgia)

We applied cultural anthropological, ethological, and parasitological methodologies to investigate the interplay among three primate species, ring-tailed lemurs (Lemur catta), Verreaux’s sifaka (Propithecus verreauxi), and humans (Homo sapiens) who live within the same habitat (i.e. in sympatry) around the Beza Mahafaly Special Reserve, Madagascar. Through a fusion of these methodologies we hope to provide a holistic understanding of the advantages and disadvantages of human-nonhuman primate sympatry. Interviews and questionnaires provided us with initial insights regarding the local peoples' attitudes toward sympatric strepsirrhine primates. Origin myths indicate a close association between humans, ring-tailed lemurs, and …

Human-Nonhuman Primate Interconnections And Their Relevance To Anthropology, Agustin Fuentes

Ecological and Environmental Anthropology (University of Georgia)

The human-nonhuman primate interface is a core component in conservation and an emerging area of discourse across anthropology. There is a growing recognition of the relevance of long-term sympatry between human and nonhuman primates. Until recently these relationships received limited attention in the anthropological literature and in the primatological construction of models for the behavior and evolution of primate societies. Most socioecological investigations into primate groups and human populations do not incorporate their interactions (beyond predation or crop raiding), potential pathogen sharing, or the role of the anthropogenically impacted environment. Current relationships between humans and nonhuman primates are generally assumed …

Oxidized Derivatives Of Ω-3 Fatty Acids: Identification Of Ipf 3Α-Vi In Human Urine, John A. Lawson, Seongjin Kim, William S. Powell, Garret Gerald A. Fitzgerald, Joshua Rokach

Chemistry and Chemical Engineering Faculty Publications

Isoprostanes (iPs) are prostaglandin-like molecules derived from autoxidation of polyunsaturated fatty acids (PUFAs). Urinary iP levels have been used as indices of in vivo lipid peroxidation. Thus far, it has only been possible to measure iPs derived from arachidonic acid in urine, because levels of iPs/neuroprostanes (nPs) derived from ω3-PUFAs have been found to be below detection limits of available assays. Because of the interest in ω3-PUFA dietary supplementation, we developed specific methods to measure nPF4α-VI and iPF3α-VI [derived from 4,7,10,13,16,19-docosahexaenoic acid (DHA) and 5,8,11,14,17-eicosapentaenoic acid (EPA)] using a combination of chemical synthesis, gas chromatography/mass spectrometry (GC/MS), andliquid chromatography tandem …

Extension Wildlife Programs: Thoughts And Ideas, Jeffrey J. Jackson

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

The following commentary is a summary of some personal thoughts, reflections, and opinions on extension wildlife programming based on my experience at the University of Georgia as Extension Wildlife Specialist during the years between 1976 and 2001. I hope it will be of some value to new specialists. Because I was the only Extension Wildlife Specialist, I was in a unique position to develop an overview of the entire wildlife management field. Along the way, I had the opportunity to be full time within Extension, have a split appointment, and be assigned to an academic department.

First-Stop Planning And Communication For Landhelp, Delwin E. Benson

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

I developed an Internet-based, planning and communication system for professional and private users to make plans for their lands, which is branded as LandHelp (www.LandHelp.info). The project was funded by grants from the Renewable Resources Extension Act, Natural Resources Conservation Service (NRCS) Wildlife Habitat Management Institute, Colorado State Forest Service, United States Department of Agriculture, Sustainable Agriculture Research and Education (USDA SARE) from the Western Region, and the United States Department of Agriculture (USDA) Agro-forestry program with the NRCS. Currently, LandHelp contains links to 31 broad categories of information that then link to 2,613 more resources. Major topics include, but …

An Internet Survey Of Private Pond Owners And Managers In Texas, Michael P. Masser, April E. Schonrock

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

The primary emphasis of this survey was to determine what specific problems Texas private impoundment owners/managers confront, how widely these problems occur, and where owners/managers get their information on pond management. A secondary emphasis was to examine the potential utilization of the Internet to gather information and distributed outreach materials. A random sample of 2,999 private impoundment (i.e., no public waters) applicants for Triploid Grass Carp Permits from Texas Parks and Wildlife was utilized as the survey mailing list. A 49-question survey was developed and placed on a secure web site. Each questionnaire contained five sections: general pond characteristics, physical …

The Above-Ground Movement And Dispersal Of The Plains Pocket Gopher (Geomys Bursarius), Craig Panich

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

The Plains pocket gopher has the largest range of its genus, and it is the gopher that inhabits much of Wisconsin. Gophers are fossorial herbivores that have a dramatic impact on natural and agricultural ecosystems. Throughout the summer of 2005, I completed a population analysis of the plains pocket gopher in a variety of habitats in Buffalo and Trempealeau Counties, Wisconsin, that provided valuable insight into the complex population dynamics of the gopher and served as a foundation to this project. Pocket gophers are known to be strictly subterranean; however, it is not uncommon to find their remains inside the …

Saving The World One Native Plant At A Time, Christopher E. Moorman, Christopher S. Deperno

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

Wildlife habitat is lost as the human population and land clearing for development increase in the South. Remaining habitats are fragmented and contain high numbers of invasive, exotic plants. Suburban, manicured landscapes often lack the plant diversity and complex vegetation structure important to wildlife. Generally, developers and homeowners replant cleared grounds with exotic plants that don’t provide quality wildlife habitat. Instead, individual home or property owners can mitigate wildlife habitat loss in urban areas by landscaping with native plants following proper design principles. Furthermore, many people taking action over a large area (e.g., across a neighborhood) will help connect small …

An Introduction To The Revised Southern Region 4-H Wildlife Projects, Renee Strnad, Chris Moorman

Triennial National Wildlife and Fisheries Extension Specialists Conference: 11th (2006)

During the 1970s, a partnership between the United States Department of Agriculture and the National 4-H Council led to the creation of the Southern Region Wildlife Project materials. Fifty-one publications, based on a variety of fish and wildlife-related subject matter, were created. In 1999, the North Carolina Department of 4-H and Youth Development received a grant from the United States Fish and Wildlife Service to revise the publications. Twenty-four of the original 51 publications were selected for revision by Extension Specialists and other wildlife biologists in several southern states. Content and format for the projects were updated in the revised …

Fisheries Research Contract Report No. 14 - Aquatic Animal Health Subprogram: Development Of A National Translocation Policy Using Abalone And Prawns As Templates For Other Aquatic Species (Frdc Project No. 2004/080) Final Report, Brian Jones, Fran Stephens

Fisheries Research Contract Reports

The use of scientifically based hazard identification, risk analysis and risk management is fundamental to managing unwanted effects. Hazards, such as quarantine incursions, will continue to occur despite the use of risk assessment methodologies but the frequency and severity of their occurrence will be reduced.

This was recognised by the Ministerial Council on Forestry, Fisheries and Aquaculture in 1999 when they published the "National policy for the translocation of live aquatic organisms".

This FRDC project provides a simple risk assessment methodology based on the Australian Standard for Risk Management (AS/NZS 4360: 2004) and one that is consistent with the Ministerial …

Are Vultures Birds, And Do Snakes Have Venom, Because Of Macro- And Microscavenger Conflict?, John A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

I outline models that describe vertebrate and microbial competition for carrion resources and help explain the resultant morphologies observed in extant vertebrate scavengers. Odors from microbial decomposition signal the presence of a carcass to vertebrate scavengers. Therefore, microbes must consume carcasses rapidly or evolve toxic defenses to protect themselves and their resource from their vertebrate competitors. Similarly, macroscavengers must evolve traits that allow rapid detection of carcasses or develop chemical defenses against microbial toxins. My modeling suggests that the most efficient macroscavenger adaptations increase the probability of carcass detection, which explains why highly vagile species, such as vultures, are the …

Assessment Of Small-Scale Biogas Systems And Their Widespread Dissemination In Can Tho City, Viet Nam, Tracy Zhu

Independent Study Project (ISP) Collection

The Mekong Delta hosts suitable conditions for promoting the widespread dissemination of biogas systems, such as tropical temperatures, high population density, and widespread animal husbandry. The low-cost polyethylene biodigester (BD) is the most common model in the Mekong Delta, although concrete and brick biodigesters have been implemented to a lesser extent. Biogas systems offer a wide range of benefits, such as improving water quality, enhancing integrated farming systems, and meeting rural energy demand while improving public health. Many projects, especially through Can Tho University (CTU), have promoted the installation of biogas systems, but little research has been done to follow …
