Development of frequency modulated vocalizations in big brown bat pups
Contributor(s): Heather W. Mayberry, Dr. Paul A. Faure (adviser)
Developing bat pups produce distinct vocalizations called isolation calls (I‐calls) that serve to attract the bat's mother. Mothers use spatial memory, auditory and olfactory cues to reunite with their offspring. Because I‐calls are unique to individual pups, vocalizations are crucial for the...

The overall goal of the studies described in this dissertation was to improve beef production of cows grazing endophyte infected tall fescue either through management practices or through identifying markers for genetic selection. Experiment 1 investigated differences in spring and fall calving...
A candidate gene association study of cryptorchidism and scrotal hernia using canine and porcine models
Contributor(s): Xia Zhao, Max Rothschild (adviser)
Cryptorchidism and scrotal hernia, both being sex-limited complex defects, are the most common congenital defects observed in humans, dogs and pigs. It is believed that these two defects are controlled by multiple genes as well as affected by environmental factors. In this thesis, 22 or 14...

Contributor(s): Carrisa Sue Pritchard, Mokhtar Harras (adviser)
This project addresses the ecological and economic roles that sheep play in Morocco in the context of Aid Al Adha celebration. It specifically examines the methods of sacrificing, butchering and preparing the different parts of the ram as part of the holiday as experienced by the researcher in a...
Habitat associations of the long-nosed potoroo (potoroos tridactylus) at multiple spatial scales
Contributor(s): Melinda A. Norton
The long-nosed potoroo (Potorous tridactylus) is a threatened, ground-dwelling marsupial known to have been highly disadvantaged by changes brought about since European settlement in Australia. Key threats to the species are believed to be fox predation and habitat loss and/or fragmentation. In...
Phylogeny, convergence, and snake behavior
Contributor(s): Harry Walter Greene
Comparative studies of snake behavior were used to confront three related conceptual issues in ethology: (i) Can behavior evolve? (ii) If so, how can the origins of similarities and differences in behavior among animals be assessed? (iii) What is the significance of this information for...
Role of abiotic factors on the development and life history of the black soldier fly, Hermetia illucens (L.) (Diptera: Stratiomyidae)
Contributor(s): Leslie Holmes
Hermetia illucens (L.) (Diptera: Stratiomyidae) has been found to successfully reduce manure in confined animal feeding operations of poultry, swine and bovine. In equatorial climates, H. illucens is active year round, however, in more temperate climates they are only active during the warmer...
Habitat use by black bears in relation to forest management in Pisgah National Forest, North Carolina
Contributor(s): Allan Joseph Brody
A total of 1310 locations was obtained on 18 radio collared black bears (Ursus americanus) in Pisgah National Forrest, North Carolina, during 1982 and 1983. Male home ranges averaged 3205 ha in summer and 6931 ha in fall. Female home ranges averaged 872 hectares in summer and 1712 hectares in...
Investigating the role of an understudied North Atlantic right whale habitat: right whale movement, ecology, and distribution in Jeffreys Ledge
Contributor(s): Kathryn Longley
The critically endangered North Atlantic right whale (Eubalaena glacialis) consistently visits five major habitats throughout the year; however, they are known to visit additional habitats. This project examines the role of Jeffreys Ledge as an additional habitat of importance for this species by...
Movement of Juvenile Lake Sturgeon (Acipenser fulvescens) in the Lower Genesee River, New York
Contributor(s): Mananjo Jonahson
As an important step in a long-term stocking program, this project investigated the movement and habitat use of juvenile lake sturgeon after they were stocked in the lower Genesee River, New York. Nine young animals were selected to represent the population, ranging from two to three years of age...
Use of injectable eugenol for euthanasia and anesthesia of American lobsters (homarus americanus) and similar species
Contributor(s): Carlton Huntsberger
Crustaceans are economically and ecologically significant, but current treatment and diagnostic protocols for crustacean health are limited. According to standards given by the American Veterinary Medical Association there are no current methods of euthanizing lobsters, nor are there effective...
Whole transcriptome response of chicken spleen and peripheral blood leukocytes to avian pathogenic Escherichia coli
Contributor(s): Erin Elizabeth Sandford, Susan J. Lamont (adviser)
A greater understanding of the immune response after infection can form the necessary foundation of knowledge needed to enhance immunity through genetic selection. Whole genome microarrays allow for comprehensive analysis of the transcriptome. The transcriptomic responses of spleen and peripheral...
Individual differences and pet ownership status: distinguishing among different types of pet owners and non-owners
Contributor(s): Shannon M. Merrill
Research examining potential differences between pet owners and non-owners is prevalent in the scientific literature, but findings have often been inconsistent. Although some researchers have incorporated animal preference into their investigations of pet ownership, such research is scarce and...
An evaluation of the endocrine response to dystocia in the primiparous cow and calf
Contributor(s): Glenda M. Borcher
Parturition is a very stressful event for both the cow and the calf. Endocrine changes occur which typically enable to calf to make the transition from a uterine to a gaseous environment. These endocrine changes are basic stress responses, necessary for an organism to maintain homeostasis. They...
