Sex, contamination and movement in an invasive fish
Animal movement has had a long history of study in the fields of behavioural ecology and toxicology, but rarely is the ecological context of behaviour in toxicology directly addressed. To explore how movement might be influenced by both sex differences and habitat contamination, I conducted...
Abundance of bottlenose dolphins (Tursiops Truncatus) in the big bend of Florida, St. Vincent Sound to Alligator Harbor
Contributor(s): Reny Blue Tyson
Mark-recapture surveys implementing photographic identification techniques were used to estimate the abundance of bottlenose dolphins in an area of the Big Bend of Florida, stretching from St. Vincent Sound to Alligator Harbor, in the summer of 2007 and winter of 2008. The current population size...
Quantitative genetic analysis of reproduction traits in ball pythons
Contributor(s): Benson H. Morrill, Lee F. Rickords (adviser)
Although the captive reproduction of non-avian reptiles has increased steadily since the 1970’s, a dearth of information exists on successful management practices for large captive populations of these species. The data reported here come from a captive population of ball pythons (Python regius)...
Osteoclast ontogeny-experimental studies in two osteopetrotic mutations in the rat: A Dissertation
Contributor(s): Matthew Joseph Cielinski
Osteopetrosis is a metabolic bone disease in mammals characterized by a generalized skeletal sclerosis caused by reduced bone resorption. This reduced bone resorption is manifested in afflicted animals by abnormal bone shape, reduced or absent marrow cavities, extramedullary hemopoiesis, abnormal...
Home range, habitat use, and food habits of the black bear in southcentral Florida
Contributor(s): Wade Allen Ulrey
I studied a small, enigmatic, and imperiled black bear population in south-central Florida from 2004 - 2006. Annual home ranges of males (96.0 km2) were larger than those of females (32.2 km2). Female home ranges were smaller in winter than in summer or fall. At the landscape scale, bears...
Reduction in mucosal barrier markers with soy protein diet but not Lactobacillus rhamnosus GG in DSS-treated mice
Contributor(s): Huanyi Jiang, Ruth S. MacDonald (adviser)
Inflammatory bowel disease (IBD) is a common ailment affecting people of all ages. Even though the pathogenesis of IBD has not been fully elucidated, there is evidence that it involves interactions between genetic susceptibility, aberrant activation of the immune system, and the environment....
Endocrine correlates of social and reproductive behaviours in a group-living Australian Passerine, the White-Browed Babbler
Contributor(s): Suzanne Oppenheimer
To investigate the evolutionary rationale for the seemingly altruistic behaviours commonly seen in cooperatively breeding Australian passerines, I examined alloparental behaviour in the White-browed Babbler Pomatostomus superciliosus (WBBA). Toward this end, I analysed behavioural, hormonal, and...
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...
Behavioral ecology of savanna chimpanzees (Pan troglodytes verus) with respect to insectivory at Fongoli, Senegal
Contributor(s): Stephanie Lynn Bogart, Jill D. Pruetz (adviser)
In this dissertation I examine the behavioral ecology of savanna chimpanzees in Senegal. I test hypotheses related to the effects of the environment on the diet of the chimpanzees at Fongoli, concentrating on their insectivory specifically. Fongoli is the hottest and driest site in which...
Developing an online horseless horse learning lesson: an action research study
Contributor(s): Jessica M. Bauman, Kathleen Lodl (adviser)
In today’s society it is becoming ever so important to find creative and influential outlets to keep young people occupied in positive ways. High quality youth programs are shown to make a positive difference in the lives of many young people; therefore, it is important to continue the use of...
Improving beef cattle performance on tall fescue
Contributor(s): Brian Thomas Campbell
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...
From pasture to plate: A study of the rituals, ecology and economics of sheep in the context of Aid Al Adha in Morocco
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...

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...
