Understanding the distribution of biodiversity across the Earth is one of the most challenging questions in biology. Much research has been directed at explaining the species latitudinal pattern showing that communities are richer in tropical areas; however, despite decades of research, a general consensus has not yet emerged. In addition, global biodiversity patterns are being rapidly altered by human activities. Here, we aim to describe large‐scale patterns of species richness and diversity in terrestrial vertebrate scavenger (carrion‐consuming) assemblages, which provide key ecosystem functions and services. We used a worldwide dataset comprising 43 sites, where vertebrate scavenger assemblages were identified using …

Ecological Interventions To Prevent And Manage Zoonotic Pathogen Spillover, Susanne H. Sokolow, Nicole Nova, Kim M. Pepin, Alison J. Peel, Juliet R.C. Pulliam, Kezia Manlove, Paul C. Cross, Daniel J. Becker, Raina K. Plowright, Hamish Mccallum, Giulio A. De Leo

Spillover of a pathogen from awildlife reservoir into a human or livestock host requires the pathogen to overcome a hierarchical series of barriers. Interventions aimed at one or more of these barriers may be able to prevent the occurrence of spillover. Here, we demonstrate how interventions that target the ecological context in which spillover occurs (i.e. ecological interventions) can complement conventional approaches like vaccination, treatment, disinfection and chemical control. Accelerating spillover owing to environmental change requires effective, affordable, durable and scalable solutions that fully harness the complex processes involved in cross-species pathogen spillover.

United States Department of Agriculture Wildlife Services: Staff Publications

BACKGROUND: Blackbird (Icteridae) damage to ripening sunflower (Helianthus annuus L.) has been a persistent economic issue in the USA for the last five decades. To quantify losses, we surveyed blackbird damage from 2001 to 2013 (excluding 2004) to physiologically mature sunflower in eight states: North Dakota, South Dakota, Texas, Nebraska, Minnesota, Colorado, Kansas, and Vermont.

RESULTS:We pooled data gathered during the most recent 5 years (2009 to 2013) of the survey and found losses averaged $US2.5 million and $US11.3 million for confectionery and oilseed hybrids, respectively. Three states, North Dakota, South Dakota, and Nebraska, had sufficient acreage and bird damage …

A Revised Land Ethic: Sustainable And Spiritual Agriculture, Brooke Maitlan Parrett

Student Theses 2015-Present

This paper proposes a return to the land and reconnection of spiritual practices through ethical teachings. Such a land ethic would involve answering the woes of industrial agriculture and providing a framework for farmers, consumers, and policymakers based on sustainable and spiritual considerations of the land. I analyze the loss of spiritual literacy and traditional ecological knowledge in the United States and discuss the spiritual history of agriculture in order to analyze contemporary religious perspectives on farming and agricultural ethics and thereby develop my own recommendations. The land ethic I propose combines sustainability and spirituality to develop intrinsic respect for …

Play Behavior And The Development Of Boldness And Caution In Juvenile Belding’S Ground Squirrels (Urocitellus Beldingi), Madelene Shehan

Master's Theses

The ubiquity of play among juvenile mammals suggests it provides adaptive benefits, potentially through influences on the development of temperament in young animals. Juvenile Belding’s ground squirrels (Urocitellus beldingi) must balance competing demands for boldness and caution imposed by the fundamental trade-off between their short active season and their vulnerability to predation. In this study, I evaluated whether play helps to facilitate the development of an appropriate balance between boldness and caution in juvenile U. beldingi.I observed the play behavior of juvenile U. beldingiand conducted flight-initiation distance tests to measure boldness-caution at the beginning and toward …

Habitat Selection By American Beaverat Multiple Spatial Scales, Guiming Wang, Lance F. Mcclintic, Jimmy D. Taylor

United States Department of Agriculture Wildlife Services: Staff Publications

Background: Semiaquatic mammals require both aquatic and terrestrial habitats, particularly interfaces between the two habitats. As ecosystem engineers, American beaver (Castor canadensis) consume and fell a great amount of deciduous trees. We tested the prediction that open water and amounts of food resources, including hardwood forests (i.e., deciduous trees as the dominant form of vegetation), herbaceous and woody wetlands, and shrubs, would influence the second-order habitat selection (i.e., placing home ranges on the landscape) by American beaver, whereas the third-order habitat selection of American beaver would be associated with woody wetland and shrub edges. We investigated hierarchical habitat selection by …

A Low-Water Crossing Impacts Movement Behavior Of Northern Hog Suckers In An Ozark Stream, Jeff Michael Williams

Graduate Theses/Dissertations

Low-water crossings are common in Ozark streams and can restrict longitudinal movement in fishes. I evaluated the impact of the Cedar Grove low-water crossing on Northern Hog Sucker Hypentelium nigricans movement behavior in Missouri’s Current River. Radio-tagged fish upstream (henceforth ‘above’; N = 24) and downstream (henceforth ‘below’; N = 26) of the crossing were followed monthly for a year to assess 1) frequency of fish passage, 2) direction of passage, and 3) maximum displacement of mobile (displacement > 1 km) fish. I then looked at diel movement behavior of stationary (displacement < 1 km) fish near the crossing to assess 1) total displacement and linear home range, 2) direction of diel displacement, and 3) habitat use. Passage was limited to four below-tagged fish and was more likely to occur in the upstream direction and during high flow. The direction of maximum displacement in mobile fish was primarily away from the crossing, and below-tagged fish exhibited over seven times greater displacement than above-tagged fish. Diel displacement and linear home range were greater in above-tagged fish, likely due to degraded upstream habitat that increased the distance between day and night habitats. My results suggest the crossing is a semi-permeable barrier that also affects local-scale movement behavior of Northern Hog Suckers. Alternatives to the low-water crossings at Cedar Grove, such as modifying the side channel into a fish bypass, should be considered to promote natural longitudinal movement of fishes in the upper Current River.

Stress And Body Composition Of Juvenile Alligator Snapping Turtles (Macrochelys Temminckii), Brandon Scott Tappmeyer

Graduate Theses/Dissertations

The alligator snapping turtle (Macrochelys temminckii), is a species of conservation concern that is the subject of multiple head-start and reintroduction efforts across its range. In captive propagation programs, producing offspring that are in optimal physiological condition maximizes the likelihood of success after release. The purpose of my study was to compare stress and body composition between one free-ranging reintroduced population and two captive populations. The two captive populations were both housed in southern Oklahoma, but one group was reared indoors whereas the other inhabited outdoor ponds at a national fish hatchery. I used circulating glucocorticoid (corticosterone) concentrations as an …

Lack Of Selective Resistance Of Influenza A Virus In Presence Of Host-Targeted Antiviral, Uv-4b, Kelly L. Warfield, Kaitlyn R. Schaaf, Lisa Evans Dewald, Kevin B.

Development of antiviral drug resistance is a continuous concern for viruses with high mutation rates such as influenza. The use of antiviral drugs targeting host proteins required for viral replication is less likely to result in the selection of resistant viruses than treating with direct-acting antivirals. The iminosugar UV-4B is a host-targeted glucomimetic that inhibits endoplasmic reticulum α-glucosidase I and II enzymes resulting in improper glycosylation and misfolding of viral glycoproteins. UV-4B has broad-spectrum antiviral activity against diverse viruses including dengue and influenza. To examine the ability of influenza virus to develop resistance against UV-4B, mouse-adapted influenza virus was passaged …

Epidemic Growth Rates And Host Movement Patterns Shape Management Performance For Pathogen Spillover At The Wildlife–Livestock Interface, Kezia R. Manlove, Laura M. Sampson, Benny Borremans, E. Frances Cassirer, Ryan S. Miller, Kim M. Pepin, Thomas E. Besser, Paul C. Cross

United States Department of Agriculture Wildlife Services: Staff Publications

Managing pathogen spillover at the wildlife–livestock interface is a key step towards improving global animal health, food security and wildlife conservation. However, predicting the effectiveness of management actions across host–pathogen systems with different life histories is an on-going challenge since data on intervention effectiveness are expensive to collect and results are system-specific.We developed a simulation model to explore how the efficacies of different management strategies vary according to host movement patterns and epidemic growth rates. The model suggested that fast-growing, fast-moving epidemics like avian influenza were best-managed with actions like biosecurity or containment, which limited and localized overall spillover risk. …

Demersal Fish Use Of Printed Oyster Shells As Nesting Habitat In North Inlet Estuary, Sc, Annie Boyd, Juliana Harding

Honors Theses

Temperate estuarine blenny species establish subtidal territories and nesting sites. Four blenny species co-occur in North Inlet, SC including the striped blenny, Chasmodes bosquianus, crested blenny, Hypleurochilus geminatus, feather blenny, Hypsoblennius hentzi, and freckled blenny, Hypsoblennius ionthas. All four fishes use empty oyster (Crassostrea virginica) shells as nesting sites. Current 3D printer technology was used to create standard nest substrates to describe relationships between blenny habitat use and nest site dimensions. Replicate printed shells of 2 gape widths (5, 7 mm) for each of 2 shell cavity volumes (22 mL, 15mL, Oyster A and …

Effects Of Temperature On Microbial Parameters Associated With Decaying Plant Litter In A Stream Microcosm Experiment, Hunter David Pates

Electronic Theses and Dissertations

Increases in mean surface air temperature under climate-change predictions are expected to affect microbial activity, as well as carbon dynamics in aquatic ecosystems. I explored responses of litter-associated decomposers along temperature ranges typical of temperate streams in laboratory microcosms simulating stream conditions. The objectives of this study were to determine (1) whether the effects of temperature on stream leaf-associated microorganisms can be explained by the Metabolic Theory of Ecology (MTE); (2) if the effects of temperature are the same across temperatures commonly found in temperate streams; and (3) if there are differences in the magnitude of responses to temperature among …

Associations Of Adiposity And Diet Quality With Serum Ceramides In Middle-Aged Adults With Cardiovascular Risk Factors, Margaret A. Drazba, Ida Holaskova, Nadine R. Sahyoun, Melissa Ventura Marra

Faculty & Staff Scholarship

Rates of adverse cardiovascular events have increased among middle-aged adults. Elevated ceramides have been proposed as a risk factor for cardiovascular events. Diet quality and weight status are inversely associated with several traditional risk factors; however, the relationship to ceramides is less clear. This study aimed to determine associations of adiposity and diet quality with circulating ceramides in middle-aged adults (n = 96). Diet quality was estimated using the Healthy Eating Index 2015 (HEI-2015). Serum ceramide concentrations were determined by liquid chromatography–mass spectrometry. A ceramide risk score was determined based on ceramides C16:0, C18:0, and C24:1 and their ratios to …

A Feasibility Study Of Industrial Hemp On Virginia Commercial Poultry Production, Aaron Sloss

Senior Honors Projects, 2010-2019

This project sought to characterize industrial hemp as a potential competitive agricultural commodity for the state of Virginia. Specifically, industrial hempseed was evaluated as a feedstock for the commercial broiler (meat-chickens) industry in Virginia.

Data were gathered to identify both the advantages and disadvantages of industrial hempseed as a nutritional resource for broilers. Key nutritional compositions were identified, quantified, and compared to several common feed ingredients, such as soybean, wheat, corn, and sorghum. Hempseed (whole seed) was found to have a considerably high amino acid content, protein, fiber, and metabolizable energy – making it an attractive alternative to conventional feedstuffs. …

Assessing Populations Of Eastern Brook Trout (Salvelinus Fontinalis) Above And Below Waterfalls In Mountain Streams Of Virginia, Hannah Eisemann Macmillan

Masters Theses, 2010-2019

Anthropogenically driven factors, such as increasing temperature and sediment in valley streams, acidification of mountain streams, and the introduction of non-native trout, are restricting habitat suitable for healthy populations of eastern brook trout (Salvelinus fontinalis) throughout their native Appalachian range. Brook trout are important as predators of insects in mountain streams and as a favorite of anglers. It is crucial that remaining populations in sustainable habitats be identified and preserved. Waterfalls are geologic knickpoints preventing base-level lowering that create unique, stable landscapes above them, which may alleviate the temperature-productivity/acidity “habitat squeeze” for populations of brook trout and could …

Contagious Yawning In The Domestic Cat (Felis Catus), Ariel M. Lombardo Aghishian

Theses and Dissertations

This study investigates contagious yawning in domestic cats towards their owners, looking at potential links with empathy. Results showed no significant difference in yawning between conditions. The solitary nature of wildcats and their shared ancestor, and the unique social behavior in domesticated cats may explain these findings.
