Implementation Of Seasonal Diets Through Seasonal Diet Surveys In Sloth Bears (Melursus Ursinus): A Case Study At Idaho Falls Zoo, Noah Clever
Undergraduate Honors Thesis Projects
Wild sloth bears (Melursus ursinus) display seasonal diet preferences for insects and fruit during the dry and monsoon season respectively. To potentially utilize as a method for reducing abnormal behaviors and improving animal welfare, the purpose of the study is to survey zoos with captive sloth bears and determine if zoo-housed individuals display seasonal diet preferences. From May 18th, 2022 to March 2nd, 2023 data was collected on Priya, a sloth bear from Idaho Falls Zoo, and her preference for fruit and insects. Temperature, season, fruit choice based on sugar levels, and insect choice based on texture of …
Impact Of Animal Programming On Human Attitudes Of Local Wildlife, Ashton Jerger
Impact Of Animal Programming On Human Attitudes Of Local Wildlife, Ashton Jerger
Undergraduate Honors Thesis Projects
Attitudes towards wildlife can have direct implications on peoples’ interest in conserving local habitats and their overall ecological choices. Attitudes are formed by multiple components of an individual’s life history. However, through interactive, educational experiences, there is a potential to change current attitudes. Animal programs are an example of interactive, educational experiences that provide individuals the opportunity to get up-close to animal ambassadors and participate in engaging conversations about them. An animal program assessment was conducted with the 2019 summer camps at the Ohio Wildlife Center to quantify the changes in peoples’ affiliation for local wildlife and their willingness to …
The Effects Of Leaf Litter On Predation Cue Response In Gray Tree Frog Tadpoles, Hyla Versicolor, Dani Mccauley
The Effects Of Leaf Litter On Predation Cue Response In Gray Tree Frog Tadpoles, Hyla Versicolor, Dani Mccauley
Undergraduate Distinction Papers
Plant litter is an important resource for consumers, particularly in freshwater environments where it influences the development processes of larval amphibians. Leaf litter alters the physiochemical environment by lowering dissolved oxygen while increasing nitrogen, tannin, and phenolic acid levels. Many anuran species show plastic responses to the threat of predation. This is communicated through a kairomone when a tadpole is consumed, allowing surviving tadpoles to alter their behavior and morphology to evade predators. The purpose of this study was to analyze the interactive effects of leaf litter and predation on gray treefrog tadpoles (Hyla versicolor). The chemical output of the …
The Relationship Between Coat Color And Dominance In Female Sable Antelope Over Time, Taylor Wilson
The Relationship Between Coat Color And Dominance In Female Sable Antelope Over Time, Taylor Wilson
Undergraduate Honors Thesis Projects
Sable antelope (Hippotragus niger)exhibit sexual dimorphism, where males and females look different from each other in color and size. Within this difference between the sexes, there are a wide spectrum in coat colors among females, ranging from light tan to dark brown. The variations seen in female coat color in other species are known to be hormonally caused by testosterone. Testosterone levels are also related to dominance within the herd in other species. The first objective of this study is to determine if the variations in coat color are associated with the dominance hierarchy among female sable …
Morphological And Color Variation In Poicephalus Parrots, Eileen Connon
Morphological And Color Variation In Poicephalus Parrots, Eileen Connon
Undergraduate Honors Thesis Projects
Though describing and delimiting species is one of the principle aspects of many disciplines within biology, there is often debate about which methods and concepts should be used to make such decisions. The Tobias criteria for quantitative species delimitation represent one attempt to create a standard method of delimiting species based on the morphological species concept. However, previous examples of using these criteria have not always been completely quantitative. This study uses quantitative morphological and color data of three Poicephalusparrots as a case study for the effectiveness of the Tobias criteria. The results show varying levels of support for …
Assessment Of Wildlife Rehabilitation Trends: Domestic Dog And Cat Attacks, Rachel Wilson
Assessment Of Wildlife Rehabilitation Trends: Domestic Dog And Cat Attacks, Rachel Wilson
Undergraduate Honors Thesis Projects
Human-wildlife conflict is a growing concern, and domestic cat predation is estimated to be responsible for billions of wildlife deaths every year in the Unites States. Domestic dog predation has been less well studied, but as dogs are the second most numerous pet in the U.S. after cats, their impact on native wildlife should also be assessed. One method to assess domestic animal predation is to examine trends in wildlife rehabilitation records. Using the online database WILD-ONe, I analyzed over 31,000 wildlife hospital records in the United States from 2011-2016. During this time span, data showed over 14,000 domestic dog …

Sibling Rivalry: A Comparison Of Giant Panda (Ailuropoda Melanoleuca) Twin Behavior, Taryn Chudo
Sibling Rivalry: A Comparison Of Giant Panda (Ailuropoda Melanoleuca) Twin Behavior, Taryn Chudo
Undergraduate Honors Thesis Projects
Expanded knowledge on an animal’s individual behavior would be useful in reintroduction programs for endangered species around the globe. Currently, reintroduction program criteria focus primarily on physical characteristics such as age, sex, and overall health for the selection of candidates. However, behavioral deficiencies have been found in captive populations, producing adverse effects on reintroduction program success. The giant panda (Ailuropoda melanoleuca) is a species that would benefit from understanding the impact of behavior on reintroduction success. This study focused on the relationship of behavior with kinship, birth weight and age. No significant correlation was found between birth weight …
Social Interactions Among Giant Panda Cubs (Ailuropoda Melanoleuca): An Investigation Into The Role Of Kin Recognition, Kelly M. Jackson
Social Interactions Among Giant Panda Cubs (Ailuropoda Melanoleuca): An Investigation Into The Role Of Kin Recognition, Kelly M. Jackson
Undergraduate Distinction Papers
Although giant pandas (Ailuropoda melanoleuca) are known to be solitary in the wild, cubs engage in frequent bouts of affiliative behavior in captive settings. The goal of the project was to investigate whether kinship or familiarity based on housing influenced the frequency of social interactions within one-year old giant panda cubs. Data were collected from June through mid-July 2016 at the Chengdu Research Base of Giant Panda Breeding, Sichuan, China. Over 113 hours of behavioral observations were recorded on four sets of twins and one singleton, focusing specifically on affiliative behaviors. Time housed together was a significant predictor of the …
Iron Metabolism Genes In Browsing And Grazing Rhinoceroses: Implications For Iron Overload Disorder, Lorien Salyer
Iron Metabolism Genes In Browsing And Grazing Rhinoceroses: Implications For Iron Overload Disorder, Lorien Salyer
Undergraduate Honors Thesis Projects
Iron overload disorder is a serious condition that affects many animals of conservation interest, including rhinoceroses. Iron overload disorder is only found in browsing rhinos (African black, Diceros bicornis, and Sumatran, Dicerorhinus sumatrensis) but not in grazing species (African white, Ceratotherium simum, and greater one-horned, Rhinoceros unicornis). Iron overload is connected with many of the other health issues seen in captive browsing rhinoceroses, so it is vitally important that the iron metabolism process is studied to improve the existing husbandry procedures of these critically endangered animals. The objective of this study was to characterize genes related to …
A Retrospective Analysis Of Trends In Central Ohio Wildlife Health Using Records From A Wildlife Rehabilitation Facility, Rachel B. Dalton
A Retrospective Analysis Of Trends In Central Ohio Wildlife Health Using Records From A Wildlife Rehabilitation Facility, Rachel B. Dalton
Undergraduate Honors Thesis Projects
The analysis of records from wildlife rehabilitation facilities has shown great potential as a technique for monitoring health trends in local wildlife populations. We examined 45,668 records of animals admitted to a wildlife rehabilitation facility located in Ohio over a 10 year period (2005-2014). The objective was to examine how causes of admission for commonly admitted species may change over time and co-vary with seasonal patterns, with the goal of using fluctuations in wildlife admissions as a monitoring technique for population and ecosystem health. We assigned causes of admission to broad categories, such as “Collision with Non-Moving Object”, and a …

Cognition And Problem Solving Using Detour Reaching And Novel Object Tasks In The Budgerigar, Mollie E. Kemp
Cognition And Problem Solving Using Detour Reaching And Novel Object Tasks In The Budgerigar, Mollie E. Kemp
Undergraduate Distinction Papers
As animal cognition is a complex and multifaceted issue, our understanding of the topic is still incomplete. Particularly, our understanding of what factors may drive the development of intricate and costly behaviors relating to cognition, like bird call or song, are not well understood. One possible explanation is the cognitive capacity hypothesis which states that song complexity is a signal of cognitive abilities and thus an indication of a mate’s ability to problem solve and thus effectively provide for offspring and mates. However, previous research of this hypothesis has yielded mixed results and has 1) focused solely on male song …
Manipulation Of Same Sex Social Pair Bonds In Budgerigars, Melopsittacus Undulatus, Amanda M. Stilwell
Manipulation Of Same Sex Social Pair Bonds In Budgerigars, Melopsittacus Undulatus, Amanda M. Stilwell
Undergraduate Distinction Papers
Same sex pair bonding can be found throughout various animal species. These relationships can be common in monogamous species, especially when there is a lack of members of the opposite sex. Budgerigars, Melopsittacus undulatus, are a socially monogamous species, which create strong pair bonds but are also known to engage in extra pair copulations. When looking at an all-male flock of budgerigars, the question arises, are these bonds easily broken or disrupted by a third party individual. After determining seven pair bonds in a flock of 32 males, these pairs were removed from an aviary and placed in separate …
A Comparison Of The Genetic Diversity Of The Class Ii Major Histocompatibility Complex In Ex Situ And In Situ Populations Of African Penguins (Spheniscus Demersus), Emily Willmer
Undergraduate Honors Thesis Projects
As an endangered species, the African penguin (Spheniscus demersus) is at risk of becoming extinct in the wild due to destruction of their coastal habitat and reduction in food availability. The development of a genetically diverse and healthy captive population is important in helping to conserve the species. The goal of this project was to determine the genetic diversity of the class II major histocompatibility complex (MHC) of a wild population of African penguins and compare it to the diversity of the captive population at Mystic Aquarium in Mystic, Connecticut that has previously been studied. We found that …
