The Art Of Amphibian Conservation: Linking In-Situ And Ex-Situ Populations Of Endangered Species Through Genome Banking, Isabella Joann Burger
The Art Of Amphibian Conservation: Linking In-Situ And Ex-Situ Populations Of Endangered Species Through Genome Banking, Isabella Joann Burger
Theses and Dissertations
Limited breeding success in captive breeding programs has necessitated the development of assisted reproductive technologies (ART) to preserve and increase genetic variation and population numbers of both captive and wild amphibian groups. ART has been shown to be successful in numerous anuran species, and current studies focus on the application of ART in ex-situ populations. The focus of this project is to show that linking in-situ and ex-situ amphibian populations through sperm cryopreservation, genome banking, and in-vitro fertilization is possible, with the goal of increasing gene diversity throughout groups in order to produce self-sustaining, wild populations in the future. Specific …

Development Of Comprehensive Theoretical Morphospaces For Canine Cranial Morphology, Alexa Ortega, Nicholas Hebdon, Lindsay Waldrop
Development Of Comprehensive Theoretical Morphospaces For Canine Cranial Morphology, Alexa Ortega, Nicholas Hebdon, Lindsay Waldrop
Student Scholar Symposium Abstracts and Posters
Throughout the evolution of the family Canidae, there is a continuous belief that canines have an exceptional olfactory system which allows them to have a heightened sense of smell. Because of this olfactory sophistication, canines have become prevalent as detection animals in the military, homeland security, law enforcement, forensics, and civilian applications. However, while the trait is highly regarded, the exact role of nasal morphology is understudied. We aim to investigate the influences of nasal cavity and internal structure morphology in odor detection. However, nasal structure is a sophisticated morphological target and requires innovative solutions to capture the key variables …

Comparative Phylogeography Across Multiple Scales: Small Mammals, Their Ecology, Pathogens, And Drivers Of Diversification, Schuyler W. Liphardt
Comparative Phylogeography Across Multiple Scales: Small Mammals, Their Ecology, Pathogens, And Drivers Of Diversification, Schuyler W. Liphardt
Biology ETDs
Comparative phylogeography has historically been defined as the study of how genetic variation of co-distributed species has been shaped by biogeographical history. This is a mature field of study out of which several techniques have been developed directed at identifying the role ecology and geography in diversification patterns across time. I employ the tools developed in classical comparative phylogeography across multiple taxonomic scales and across regions that historically have been understudied. My first two chapters study the complex history of host-switching, codiversification, and reassortment of hantaviruses in their mammal hosts across North America. By taking a host-centric comparative phylogeographic approach …
Cetacean Acousticwelfare In Wild And Managed-Care Settings: Gaps And Opportunities, Paige E. Stevens, Heather Hill, Jason N. Bruck
Cetacean Acousticwelfare In Wild And Managed-Care Settings: Gaps And Opportunities, Paige E. Stevens, Heather Hill, Jason N. Bruck
Faculty Publications
Cetaceans are potentially at risk of poor welfare due to the animals’ natural reliance on sound and the persistent nature of anthropogenic noise, especially in the wild. Industrial, commercial, and recreational human activity has expanded across the seas, resulting in a propagation of sound with varying frequency characteristics. In many countries, current regulations are based on the potential to induce hearing loss; however, a more nuanced approach is needed when shaping regulations, due to other non-hearing loss effects including activation of the stress response, acoustic masking, frequency shifts, alterations in behavior, and decreased foraging. Cetaceans in managedcare settings share the …
Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan
Monitoring Mammals At Multiple Scales: Case Studies From Carnivore Communities, Kadambari Devarajan
Doctoral Dissertations
Carnivores are distributed widely and threatened by habitat loss, poaching, climate change, and disease. They are considered integral to ecosystem function through their direct and indirect interactions with species at different trophic levels. Given the importance of carnivores, it is of high conservation priority to understand the processes driving carnivore assemblages in different systems. It is thus essential to determine the abiotic and biotic drivers of carnivore community composition at different spatial scales and address the following questions: (i) What factors influence carnivore community composition and diversity? (ii) How do the factors influencing carnivore communities vary across spatial and temporal …
The Behaviors Of A Captive Father-Daughter Pair Of Ateles Geoffroyi Geoffroyi, Felicia Gordian
The Behaviors Of A Captive Father-Daughter Pair Of Ateles Geoffroyi Geoffroyi, Felicia Gordian
The Pegasus Review: UCF Undergraduate Research Journal
The Central Florida Zoo and Botanical Gardens intends to introduce new members to the black-handed spider monkeys (Ateles geoffroyi geoffroyi) enclosure. The behavioral analysis of captive animals within their human-made zoo environments is pertinent information for zookeepers before such an introduction can be made. To contribute to that goal, this study observed the behaviors of a father-daughter pair of black-handed spider monkeys. This study observed their vocalizations, habitat utilization, enrichment utilization, conspecific interactions, and interactions with humans to better understand how they interact with their environment as well as their group dynamics. This behavioral baseline can then be utilized to …
Does It Take A Community To Save A Species? Examining The Use Of Community Interactions To Restore Unionid Species At Risk, Roland Adriaan Eveleens
Does It Take A Community To Save A Species? Examining The Use Of Community Interactions To Restore Unionid Species At Risk, Roland Adriaan Eveleens
Electronic Theses and Dissertations
The conservation and restoration of freshwater ecosystems are complex. Knowledge from community ecology, conservation biology, and restoration ecology was integrated to interrogate the role of species interactions involving freshwater mussels (order Unionida) as keystone species. Freshwater mussels require host fish and provide ecosystem functions for other species throughout aquatic and riparian ecosystems, yet conservation efforts remain focused on focal mussel species or host fish associations. My thesis explored species co-occurrences within mussel and benthic macroinvertebrate community assemblages, and systematically reviewed the published literature to assess the breadth and reported effectiveness of mussel restoration. Community analyses confirmed species co-occurrences across environmental …

Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath
Laryngeal Vocals In Old World Locals: Air Sacs Usage In Bonobos, Chelsea Trenbeath
Symposium of Student Scholars
Except for humans, extant great apes have evolutionarily conserved lateral ventricular air sacs extending from laryngeal saccules. Humans are the only species of Hominidae that lack this anatomical feature attached to the primary vocal apparatus. As we are the only species that produces spoken language, this association has led to hypothesis that the loss of lateral ventricular air sacs was necessary for the evolution of spoken language. However, why these sacs are conserved in all other hominids remains unclear. Computer modeling has indicated that air sacs may increase resonance properties, but there are no data from great apes indicating which …

Effects Of Early Corticosterone Treatment On Vocal Babbling In Wild Green-Rumped Parrotlets (Forpus Passerinus), Celia Rose Mclean
Theses and Dissertations
The stress axis of the endocrine system allows for animals to respond to environmental stressors in contextually appropriate ways. Elevated levels of the stress hormone corticosterone (CORT) in male songbirds can result in compromised song learning ability. Parrots form a sister group to songbirds, but it is unknown whether CORT affects vocal development in parrots. The goal of this study was to assess the effects of CORT supplements in green-rumped parrotlets (Forpus passerinus), a free-ranging parrot species in Venezuela. Bouts of vocal babbling were extracted from nest box videos and analyzed. CORT supplementation resulted in differences in babbling …
Neurotranscriptomic Changes Associated With Chick-Directed Parental Care In Adult Non-Reproductive Japanese Quail, Patricia C. Lopes, Robert De Brujin
Neurotranscriptomic Changes Associated With Chick-Directed Parental Care In Adult Non-Reproductive Japanese Quail, Patricia C. Lopes, Robert De Brujin
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
For many species, parental care critically affects offspring survival. But what drives animals to display parental behaviours towards young? In mammals, pregnancy-induced physiological transformations seem key in preparing the neural circuits that lead towards attraction (and reduced-aggression) to young. Beyond mammalian maternal behaviour, knowledge of the neural mechanisms that underlie young-directed parental care is severely lacking. We took advantage of a domesticated bird species, the Japanese quail, for which parental behaviour towards chicks can be induced in virgin non-reproductive adults through a sensitization procedure, a process that is not effective in all animals. We used the variation in parental responses …

The Effect Of Freeze-Thaw Events On Dna Integrity In The Gray Treefrog (Hyla Versicolor), Georgia Ficarra
The Effect Of Freeze-Thaw Events On Dna Integrity In The Gray Treefrog (Hyla Versicolor), Georgia Ficarra
Masters Theses & Specialist Projects
Freeze-tolerant gray treefrogs survive winter by producing natural cryoprotectants and accommodating ice formation within extracellular spaces. While frozen, gray treefrogs endure hyperglycemia, dehydration, and anoxia due to the halt of all bodily functions. Upon thawing, the frogs’ anoxic cells receive a rapid influx of oxygen, which can cause oxidative damage to vital macromolecules including DNA. Previous studies have suggested freeze-tolerant frogs avoid oxidative damage after freeze-thaw events by elevating antioxidant activity, but recent work has shown upregulated DNA repair encoding genes in post-freeze frogs. The objective of this thesis is to assess the cellular costs of freezing by measuring oxidative …

Effects Of Synthetic Estrogen (17Α-Ethinyl Estradiol) On Male Fiddler Crab Aggression, Micayla Shirley
Effects Of Synthetic Estrogen (17Α-Ethinyl Estradiol) On Male Fiddler Crab Aggression, Micayla Shirley
Honors College Theses
Pharmaceuticals, including hormones and antibiotics, are considered contaminants due to their widespread use and release into the environment. Hormones, like the synthetic estrogen used in oral contraceptives (17α-ethinylestradiol), are present in freshwater and marine systems, but with relatively unknown effects on the organisms that live there. Ethinylestradiol (EE2) accumulates in waterlogged soil (sediment) with potential to harm sediment-dwelling animals. For example, fiddler crabs (Uca pugilator) are vital members of salt marsh communities. Their burrowing adds oxygen to sediments and cycles nutrients, and they are an important food resource to birds and raccoons. Male fiddler crabs are territorial, aggressively …
Is The Dewlap An Honest Signal Of Fighting Ability In The Male Green Anole (Anolis Carolinensis)?, Alexia Hughes
Is The Dewlap An Honest Signal Of Fighting Ability In The Male Green Anole (Anolis Carolinensis)?, Alexia Hughes
Graduate Theses
Signals are morphological or behavioral traits that an individual uses to influence the behavior or actions of another. These signals can be used in male-male competition, in which male secondary sexual traits act as a signal of his fighting ability. Animal signals are considered honest when the signal reliably indicates a specific trait or condition of the individual. The genus Anolis, comprised of over 400 species that occupy the tropics and the southeastern United States, utilize aggressive signaling prior to physical combat. Research on several tropical species of anole indicates that the size of their dewlap can act as an …
Natural Noise Can Influence Bird Foraging And Vigilance Behavior, Kate Antonia Sweet
Natural Noise Can Influence Bird Foraging And Vigilance Behavior, Kate Antonia Sweet
Boise State University Theses and Dissertations
Natural sounds are an often overlooked, yet important component of an animal’s habitat. The acoustic environment may be especially significant during foraging, because a noisy world can limit auditory surveillance. Here, we investigated how natural noise structures the foraging vigilance trade-off to understand how intense acoustic environments may have shaped antipredator behavior across the evolutionary past, and better inform conservation efforts in the present.
First, in Chapter 1, I directly compared the foraging and vigilance behaviors of captive song sparrows (Melospiza melodia) in anthropogenic and natural noise. We recorded foraging trials in 4 playback conditions (roadway traffic, whitewater …

Climate-Driven Impacts On Himalayan Aquatic Biodiversity: A Case Study Involving Snowtrout (Cyprinidae: Schizothorax), Riri Wiyanti Retnaningtyas
Graduate Theses and Dissertations
Monitoring biodiversity, to include its relative dispersal and contraction, has become a conservation task of great importance, particularly given the catastrophic and ongoing loss of habitat due to climate change. However, the timing, direction, and magnitude of these rates vary across taxa and ecosystems. Predicting specific impacts of climate change can thus be difficult and this, in turn, hampers management action. Metrics are needed to not only quantify contemporary requirements of species, but also predict potential distributions that fluctuate in lockstep with climate.
Montane ecosystems in the Himalayas are highly impacted by climate change, yet remain largely understudied due to …
