Does Social Organization, Litter Size, Sexual Dimorphism, And Phylogeny Influence Multiple Paternity In Mammals?, Madison Roberts

Honors Theses

Animal social systems are complex and the dynamics of one component could influence the dynamics of another. The aim of this literature search research was to determine the interrelatedness between mammalian social organization and mating system, two components of social systems. The mating system was represented by multiple paternity, the number of litters with more than one father, as genetic analysis tells which individuals reproduced with who. Variables that might influence multiple paternity amongst extant mammalian species included in this study are variable social organization, male social organization, mean litter size, sexual dimorphism, and phylogenetics. Analysis was conducted using 56 …

Neuronal Effects Of Cocaine In An Animal Model Of Social Stress: Analysis Of Neuronal Recordings, Eboni Eddins

Honors Theses

Studies that use Intermittent (episodic) Social Defeat (ISD) in rats demonstrate that ISD increases cocaine-self administration several weeks after the end of the adverse experience and suggest that a history of social stress makes individuals more vulnerable to substance abuse in the long term. The medial prefrontal cortex (mPFC) plays a key role in regulating drug-seeking behavior. The present study investigates whether ISD enhances the response of mPFC neurons to cocaine. Male Long Evans rats (3-4 months) were implanted with electrode arrays in the mPFC (prelimbic area) and divided into two groups (Control, n= 4; Stress, n= 4). They were …

The Influence Of Body Temperature On Motion Patterns On Anolis Lizard Visual Display, Timothy P. Fagan

Honors Theses

Anolis sagrei has a display in the form of bobbing its head up and down. In order to more accurately understand the communication and honesty of the display two experiments were done. Honesty, in reference to it being an honest signal; meaning that this form of communication is correlated with the condition of the animal. The first experiment examined the lizards in a recreated environment. By controlling the temperature of the setting and recording the interaction we were able to determine how changing the temperature could cause a difference in display. The second experiment examined the lizard's ability to see …

Finding Identity In The Intersections: Transnational Feminism And The Non-Human Primate, Kailyn Carr

Honors Theses

This project examines how the conversations among feminism and primatology offers a unique critical lens into how “man” dominates other identities, whether that be woman or non-human primate, specifically within the rigid colonial structures of Western society. Donna Haraway’s landmark post-humanist work joins these conversations, especially with her earlier work Primate Visions and Simians, Cyborgs, and Women. While Haraway has changed the narrative surrounding feminist theory within the biological sciences – what has now become recognized as feminist science and technology studies –, this shift in perspective continues to emphasize Western ideological practices and their attention to primatology. My …

Conditioned Territory Defense In Madagascar Hissing Cockroaches (Gromphadorhina Portentosa), Macy R. Albaitis

Honors Theses

In male blue gourami fish (Trichogaster trichopterus), signaled presentation of a male rival produces an aggressive conditioned response that results in an increased likelihood of the male winning the contest (Hollis, 1984). I replicated this classic study in a species that also shows territorial aggression: the Madagascar hissing cockroach (MHC; Gromphadorhina portentosa). During training, four adult male MHCs were designated as “CS+” animals and received a light (NS) followed by visual access to a rival male (US). Simultaneously, another group of four adult male MHCs designated as “UNC” animals received the light (NS) and visual access to a …

Winner And Loser Effects In Madagascar Hissing Cockroaches (Gromphadorhina Portentosa), Casey Mack

Honors Theses

Winner and loser effects have been documented in many species throughout the animal kingdom, but have yet to be investigated in Madagascar hissing cockroaches. This study seeks to determine if winner or loser effects are present in Madagascar hissing cockroaches. In Experiment 1, three subjects won a training contest and three subjects lost a training contest. Training contest winner and training contest loser subjects were then paired up in test contests. Four of the 6 subjects showed test contest outcomes consistent with their training contest outcomes, but the overall conclusions were ambiguous due to the small sample size. Whether the …

Analysis Of Multigenerational Behavioral Effects Of Dietary Benzo[A]Pyrene Exposure In Adult Zebrafish, Mary Beth Gillespie

Honors Theses

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon that is linked to negative reproductive and developmental effects in humans and animals. Because BaP is carcinogenic, and its continued presence in the environment allows it to be inhaled and ingested, better understanding of the effects of BaP is needed. To determine the behavioral effects of BaP exposure, zebrafish were used as a model. Wild-type zebrafish (5D) underwent two separate 21-day dietary exposures to 2.5 and 25 μg BaP/g fish to compare how BaP exposure affects locomotor activity. Following the dietary exposure, fish were mated to obtain and raise the F1 generation to …

Predictors Of Separation Anxiety In Dogs, Mckenna Yohe

Honors Theses

Understanding the potential causes and risk factors associated with separation anxiety in dogs is necessary to provide insight for possible prevention measures and to maintain the health and well-being of the animals affected by this condition. While a considerable amount of research has been done on this subject, it is still unclear what specific characteristics of dogs and their owners relate to the occurrence of separation anxiety and related behaviors. This study aimed to reexamine several dog and owner characteristics that have previously been evaluated in relation to the incidence of separation anxiety, as well as investigate how the frequency …

A Foray Into The Interval Timing Capabilities Of Tufted Capuchin Monkeys (Cebus [Sapajus] Apella), Gryff Griffin

Honors Theses

Time is a critical part of life and timing on the range from milliseconds to minutes has proven to be critical for several behaviors such as foraging and movement. While the exact neurological structures of interval timing are currently undefined, several studies have been completed comparing the interval timing capabilities of humans and nonhuman primates. However, these studies have unanimously utilized members of Macaca, which limits the abilities for researchers to make apt comparisons between humans and all nonhuman primates. This study sought to investigate whether tufted capuchins (Cebus [Sapajus] apella) have the capability to measure time …

Effects Of Perceived Audiences On Discrimination Learning In Pigeons ( Columbia Livia ), Peyton M. Mueller, Matthew Murphy

Honors Theses

The social facilitation effect is a phenomenon frequently discussed in the subfield of social psychology. Some studies have examined the social facilitation or inhibition effects in nonhuman animals, though few have examined the effect of perceived audiences on their cognitive functioning. In order to study this effect, three different video stimuli were presented to one subject while solving a memorization discrimination task. It was hypothesized that the pigeon would learn a task at different rates based on the type of perceived audience presented. No significant results were found due to the fact that the subject was unable to learn the …

Personality Traits As Predictors Of Pair-Housing Compatibility In Garnett's Greater Bushbabies (Otolemur Garnettii), Karen A. Schaffer

Honors Theses

Continuously refining husbandry strategies to improve the welfare of captive primates is a research priority. A variety of enrichment strategies are employed to allow captive primates opportunities to exercise natural behaviors with the aim of maintaining their psychological health in environments different from those for which they evolved. Arguably the most important of these strategies is social housing, since primates are by definition social animals. Pair housing is often the most logistically feasible method; however, the process of introducing partners to each other comes with risks of stressful conflict that may result in injury, and the necessarily trial-and-error nature of …

Predatory Nature And Food Preferences Among Captive Otolemur Garnettii, Morgan N. Ruby

Honors Theses

Observing the predatory nature in primates has yielded knowledge pertaining to their biology and evolutionary pathways; however, not many studies have focused on the complexities of their food preferences. This thesis focuses on food preferences among Garnett’s Greater Bushbaby (Otolemur garnettii): a small-bodied nocturnal primate native to Central and Southern Africa. Presented food options were raisins: dried mealworms and raisins: live mealworms. The population consists of fifteen bushbabies housed in The University of Southern Mississippi (USM) Primate Behavior Research Facility. Ten trials of three different experiments were performed to identify the dominant hand and food preferences among the …

Mating Behaviors Exhibited By A Captive Male Pacific Walrus (Odobenus Rosmarus Divergens), Jessica M. Mccord

Honors Theses

Understanding mating behaviors of a species can be utilized to help protect the species. Results of population surveys have shown the walrus population to be on the decline, and over the history of walruses being held in captivity, few pups have been born or survived. Not much is known about Pacific walruses (Odobenus rosmarus divergens) due to the isolated Arctic habitats in which walruses live making wild population studies difficult. Few studies have examined wild observations of walrus mating behaviors and virtually none for captivity. The purpose of this study was to observe a captive male Pacific walrus for mating …

Distribution And Paleobiology Of Hibernation In Fossil Ground-Dwelling Squirrels From The Great Plains, Usa, Randy Sanchez

Honors Theses

Hibernation is a widespread phenomenon present across mammalian taxa, including in many ground-dwelling squirrels (family Sciuridae). Prior work has shown that a hibernation mark can be identified in the ever-growing incisors of these ground squirrels through surface inspection. In this study, we inspected fossil incisors, originating from the Great Plains, from the C.W. Hibbard collection at the University of Michigan for features associated with hibernation marks in modern species. We noted hibernation mark-like features in several fossil ground squirrel incisors from the genera Otospermophilus, “Spermophilus”, and Urocitellus, ranging stratigraphically from the early Pliocene to the late Pleistocene and providing the …

The Historical Ecology Of Queensland’S Australian Saltwater Crocodile (Crocodylus Porosus), Emily M. Walker

Honors Theses

Human wildlife conflict is a critical aspect of many societies, as it often plays a large role in government decisions. The iconic saltwater Australian crocodile (Crocodylus porosus) is one example of a species that has become the subject of human-wildlife conflict in Queensland, Australia. Decades of intensive hunting in Queensland, beginning at the time of the Second World War, drastically depleted crocodile populations, leading to a federal embargo on crocodile exports in 1972 and their protection in Queensland in 1974. Since protection, populations appear to be recovering with increasing densities in the north and increased sightings along the …

The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed

Honors Theses

Endocrine-disrupting chemicals (EDCs), such as those from plastics and pesticides, have been hypothesized to affect wildlife populations. According to the U.S. National Institute of Environmental Health Sciences, EDCs ‘are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.’ A growing number of studies suggest wildlife are being exposed to EDCs, but how EDCs affect wildlife health and wildlife conservation is less well-understood. Through scientific literature analysis and a survey of wildlife conservationists and practitioners, this study aims to determine the current state of knowledge and data …

A Study Of Vegetarianism And Meat Analogs, Paula Herrin Hendr

Honors Theses

Food is the structure of society's structure. It shows the values, customs, and habits of the people. For many years now we have applauded the frozen foods, packaged foods, TV dinners, fast food franchise, preservatives, additives, and anything else that would save time. Our values are slowly changing. In our new culture we have time for growing gardens and things like baking bread. Our eating and cooking has become more of a ceremony. The variety of foods is endless but some people will prefer some foods over others.

A vegetarian is one who does not use meat in his diet …
