Animal Conservation In St. Louis, Kate O'Sullivan
Animal Conservation In St. Louis, Kate O'Sullivan
Undergraduate Research Symposium
St. Louis has a multitude of organizations involved in the natural sciences. But how many of them actually contribute towards animal conservation? The St. Louis Zoo is an organization that focuses a lot of its effort on presentation, so how does that impact the funds that go towards actually saving the animals? I plan to dive into the different animal-based organizations in St. Louis and its surrounding areas, as well as discuss the positives and negatives of each organization. Furthermore, I will provide examples from several sources that I have been reviewing all year to support my claims. I plan …
The Influence Of Hiking Trails On Salamanders, Emily M. Macdonald
The Influence Of Hiking Trails On Salamanders, Emily M. Macdonald
IdeaFest: Interdisciplinary Journal of Creative Works and Research from Cal Poly Humboldt
Over half of the World’s salamanders are facing extinction. It is important to understand the impact Humans have on them in all parts of their ranges so we can better understand what they need and how we can prevent further extinctions. I conducted this study to try to determine if the human activity on the official hiking trails in the Arcata Community Forest in Arcata California; as designated by the official map of the Forest; is negatively impacting the salamanders that live in the Forest. I thought there would be an increase in the number of species and the overall …

Acoustic Sampling Of Arkansas Bat Species Richness Across Different Seasons And Habitats, Lark E. Sybrant
ATU Research Symposium
Arkansas is home to sixteen bat species belonging to the Vespertilionidae and Molossidae families. Bats are keystone species and provide numerous ecosystem services that also benefit people. This study explores factors that impact species richness between the spring and fall seasons in a wooded rural site (Washburn Park) and an urban field site (Arkansas Tech University campus), Russellville, AR. The non-invasive Echo Meter Touch 2 Pro, from Wildlife Acoustics, was used to record calls and identify bat species from these locations. Nearly 1,050 calls were recorded from 11 different species across the spring and fall between both sites. Results showed …

Methylene Blue Inhibits Cromakalim-Activated K+ Currents In Follicle-Enclosed Oocytes, Dmytro Isaev, Keun-Hang Susan Yang, Georg Petroianu, Dietrich Ernst Lorke, Murat Oz
Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The effects of methylene blue (MB) on cromakalim-induced K+ currents were investigated in follicle-enclosed Xenopus oocytes. In concentrations ranging from 3–300 μM, MB inhibited K+ currents (IC50: 22.4 μM) activated by cromakalim, which activates KATP channels. MB inhibited cromakalim-activated K+ currents in a noncompetitive and voltage-independent manner. The respective EC50 and slope values for cromakalim-activation of K+ currents were 194 ± 21 µM and 0.91 for controls, and 206 ± 24 µM and 0.87 in the presence of 30 μM MB. The inhibition of cromakalim-induced K+ currents by MB was not …
Genetic Protocols For Dna Extraction From White-Tailed Deer Cast Antlers To Confirm Individuality, Zach Carter, Brian C. Peterson, Casey W. Schoenebeck, Kimberly A. Carlson
Genetic Protocols For Dna Extraction From White-Tailed Deer Cast Antlers To Confirm Individuality, Zach Carter, Brian C. Peterson, Casey W. Schoenebeck, Kimberly A. Carlson
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
White-tailed deer (Odocoileus virginianus) are the most sought-after deer species in America. The antlers of mammals, such as deer, are one of the fastest regenerative tissues in the world and are grown and naturally cast every year. Research on cast antlers have been used for a variety of purposes including population comparisons and impacts of deer health due to climatic stressors. When investigating cast antlers, it is important to confirm individuality of match sets in addition to antlers of the same individual between years. Therefore, individuality must be confirmed genetically, and protocols must be developed and established to …
Can Financialization Save Nature? The Case Of Endangered Species, Diane-Laure Arjalies, Delphine Gibassier
Can Financialization Save Nature? The Case Of Endangered Species, Diane-Laure Arjalies, Delphine Gibassier
Business Publications
The current biodiversity loss is dramatic. Over the past 50 years, more than 68% of the mammals, birds, amphibians, reptiles, and fish on earth have disappeared, putting the planet's survival and its inhabitants – including human beings – at risk (WWF, 2020). Financialization, or the transformation of nature into financial assets, is increasingly proposed as a solution to the biodiversity crisis. Proponents of financialization believe that assigning a monetary value to nature will incentivize human beings to protect habitats and their species. This article offers a four-mechanism model of nature’s financialization, explaining why it is virtually impossible to financialize nature. …
Reconstructing The Ecological Relationships Of Late Cretaceous Antarctic Dinosaurs And How Functional Tooth Morphology Influenced These Relationships, Ian D. Broxson
2022 Symposium
The Sandwich Bluff Formation of the James Ross Basin of Antarctica has recently yielded a group of five late Cretaceous dinosaurs that lived contemporaneously with each other, a first for Antarctica. These five dinosaurs include fragmentary remains of two differently sized elasmarian ornithopods, a possible megaraptor, a hadrosaur, and a nodosaur. In this study we will construct a model of the ecological relationships of late Cretaceous Antarctica. Additionally, we will look at what specific factors allowed this group of four herbivores and a carnivore to coexist in a restricted locality and what niches were filled by each species. Methods to …
Effects Of Cottonseed Meal Containing Gossypol On Testis Physiology In Boars, Kristin Ryan
Effects Of Cottonseed Meal Containing Gossypol On Testis Physiology In Boars, Kristin Ryan
Animal Science Undergraduate Honors Theses
Feral hogs are an invasive species found in 35 U.S. states without an effective control method to limit their population growth. According to a 2019 survey of 467 landowners in Arkansas, feral hogs caused an estimated $12 million in damages (Cook, 2019). While there are current control methods such as hunting and trapping, 65% of the feral hog population must be eliminated in a specific area to prohibit population growth (Cook, 2019). It is theorized that gossypol, a phenolic compound known to negatively impact reproductive function in other species, could cause sterility in boars. In this preliminary research study, 21 …

Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh
Ontogenetic Drivers Of Morphological Evolution In Monitor Lizards And Allies (Squamata: Paleoanguimorpha), A Clade With Extreme Body Size Disparity, Carlos J. Pavón-Vázquez, Damien Esquerré, J. Scott Keogh
Publications and Research
Background
Heterochrony, change in the rate or timing of development, is thought to be one of the main drivers of morphological evolution, and allometry, trait scaling patterns imposed by size, is traditionally thought to represent an evolutionary constraint. However, recent studies suggest that the ontogenetic allometric trajectories describing how organisms change as they grow may be labile and adaptive. Here we investigated the role of postnatal ontogenetic development in the morphological diversification of Paleoanguimorpha, the monitor lizards and allies, a clade with extreme body size disparity. We obtained linear and geometric morphometric data for more than 1,600 specimens belonging to …

Impact Of Covid-19 On Aviation-Wildlife Strikes Across Europe, Isabel C. Metz, Marta Giordano, Dionysios Ntampakis, Marianna Moira, Anneke Hamann, Rosanne Blijleven, Jürgen J. Ebert, Alessandro Montemaggiori
Human–Wildlife Interactions
Collisions between aircraft and wildlife (i.e., wildlife strikes) pose a serious threat toward the safety of aircraft, its crew, and passengers. The effects of COVID-19 related travel restrictions on wildlife strikes are unknown. With this study, we aim to address this information gap by assessing the changes of wildlife hazard management performance across European airports during the lockdown period (e.g., period of reduced operations and borders closure in spring 2020). We also sought to raise awareness of the importance of wildlife strike prevention in times of reduced operations. The objective of our study was to compare wildlife strike data before …
Understanding Caribou Population Cycles, Jack R. St. John
Understanding Caribou Population Cycles, Jack R. St. John
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The complex population dynamics of caribou (Rangifer tarandus) were studied to determine the patterns of their population cycles and the processes driving them. It is well established, via previous archaeological research and Indigenous knowledge, that large migrating caribou herds found in and around the tundra at northern latitudes experience population boom and busts roughly every several decades. However, the processes driving the dynamics of these cycles are relatively unknown, which makes managing caribou herds for recreational and subsistence harvests difficult. It has been hypothesized that a combination of intrinsic and extrinsic factors shape these cycles, with density-dependence, predation, …

Human–Wildlife Interactions
Mitigation translocation remains a popular conservation tool despite ongoing debate regarding its utility for population conservation. To add to the understanding of the effectiveness of mitigation translocation, in 2017 and 2018 we monitored a population of protected common chuckwallas (Sauromalus ater) following translocation away from the area of construction of a new highway near the South Mountains, Phoenix, Arizona, USA. We removed chuckwallas from the construction right-of-way, paint-marked and pit-tagged them, and then released them in a nearby municipal preserve. We deployed very high frequency radio-telemetry transmitters on a sub-sample of 15 translocated adult chuckwallas. We monitored the …
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 …

Forest Disturbance And Occupancy Patterns Of Carnivores: Results Of A Large-Scale Field Study In Maine, Usa, Bryn E. Evans
Electronic Theses and Dissertations
Understanding trends in the abundance and distribution of carnivores is important at global, regional and local scales due to their ecological role, their aesthetic and economic value, and the numerous threats to their populations. Carnivores in Maine range from the American black bear (Ursus americanus), to numerous native mesocarnivore species, such as American marten (Martes americana), fisher (Pekania pennanti), coyote (Canis latrans), red fox (Vulpes vulpes), bobcat (Lynx rufus), Canada lynx (Lynx canadensis) and to two small weasel species (Mustela erminea and Neogale frenata). …
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 …

ESI Publications
Unequal outcomes disrupt cooperation in some situations, but this has not been tested in the context of coordination in economic games. To explore this, we tested brown capuchins (Sapajus [Cebus] apella) on a manual version of the Stag Hunt (or Assurance) Game, in which individuals sequentially chose between two options, Stag or Hare, and were rewarded according to their choices and that of their partner. Typically, coordination on Stag results in an equal highest payout, whereas coordinating on Hare results in a guaranteed equal but lower payoff and uncoordinated play results in the lowest payoff when playing …

Intensive Hunting Pressure Changes Local Distribution Of Wild Boar, Jakub Drimaj, Jiří Kamler, Radim Plhal, Přemysl Janata, Zdeněk Adamec, Miloslav Homolka
Human–Wildlife Interactions
Wild boar (Sus scrofa) is now an important species of wild ungulates in Central Europe. Next to conflicts of wild boar with agriculture, the main threat of wild boar presence lies in the expansion of African swine fever across Europe. The regulation of the wild boar population is complicated by the high reproduction rate and intelligent behavior of the species, which limits hunting effectiveness. We analyzed the spatial behavior of wild boar in an environment with a lack of natural food resources. The study area consisted of a forest complex (1,283 ha) with 2 areas. In the “risk” …
Self-Injurious Behavior In A Captive, Malimprinted Coragyps Atratus, Brittany Swartout
Self-Injurious Behavior In A Captive, Malimprinted Coragyps Atratus, Brittany Swartout
The Pegasus Review: UCF Undergraduate Research Journal
Lurch is a Coragyps atratus who was raised in captivity and imprinted on humans. He was an education animal at the Silver Springs Zoo until its closure. Lurch was moved to the Central Florida Zoo and has been feather picking and self-mutilating since then. Self-injury is not well documented in raptors and few treatments have been explored. It is often caused by stress of some sort and is not seen in the wild. These observations were conducted in order to observe the environmental factors that influenced these behaviors in Lurch. In an attempt to curb his feather picking, Lurch was …
A Behavioral Study Of Chacoan Peccaries (Catagonis Wagneri) In A Zoo Environment, Desdemona Kurowski
A Behavioral Study Of Chacoan Peccaries (Catagonis Wagneri) In A Zoo Environment, Desdemona Kurowski
The Pegasus Review: UCF Undergraduate Research Journal
Found in the highly specialized area of the Gran Chaco, the Chacoan peccary (Catagonis wagneri) is an endangered animal threatened by industrial agriculture. In an attempt to save this species, three C. wagneri were brought to Central Florida Zoo where their health is monitored with great care in an attempt to possibly breed them in the future. While taking care of the other hooved animals, zookeepers are not able to give the peccaries their uninterrupted attention and have turned to help from the University of Central Florida to closely track if their behavior is indicative of a healthy, properly enriched …

Body And Tail Coordination In The Bluespot Salamander (Ambystoma Laterale) During Limb Regeneration, Cassandra M. Donatelli, Keegan Lutek, Keshav Gupta, Emily M. Standen
Engineering Faculty Articles and Research
Animals are incredibly good at adapting to changes in their environment, a trait envied by most roboticists. Many animals use different gaits to seamlessly transition between land and water and move through non-uniform terrains. In addition to adjusting to changes in their environment, animals can adjust their locomotion to deal with missing or regenerating limbs. Salamanders are an amphibious group of animals that can regenerate limbs, tails, and even parts of the spinal cord in some species. After the loss of a limb, the salamander successfully adjusts to constantly changing morphology as it regenerates the missing part. This quality is …
Sublethal Effects Of Red Imported Fire Ant Envenomation On Hatchlings Of North American Oviparous Snakes, Hannah Warner, Meredith Swartwout
Sublethal Effects Of Red Imported Fire Ant Envenomation On Hatchlings Of North American Oviparous Snakes, Hannah Warner, Meredith Swartwout
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
Invasive species cause major ecological and economic damage. The Red Imported Fire Ant (RIFA; Solenopsis invicta) has successfully invaded much of the southeastern United States and has caused both widespread economic damage and is suspected to be the driver of enigmatic declines of several oviparous snake species. This study aimed to determine the sublethal effects of RIFA on hatchlings of six species of oviparous snakes (Coluber constrictor, Lampropeltis calligaster, L. holbrooki, Opheodrys aestivus, Pantherophis emoryi, and P. obsoletus) by exposing hatchlings to envenomation by RIFA and then measuring two performance metrics: righting response and …
Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger
Morph- And Sex-Specific Differences In Corticosterone Of The Arizona Tiger Salamander (Ambystoma Mavortium Nebulosum), Megan Zerger
Scholars Week
Life history morph, sex, and body condition are traits that may influence stress within salamander populations because of differences in physiology and environmental conditions. Given widespread declines and the effects chronic stress can have on amphibian health, it is important to understand within-population drivers of stress and how population level variation may influence population viability. Thus, the objective of our study was to assess how corticosterone varies within the Arizona tiger salamander (Ambystoma mavortium nebulosum) population at the Mexican Cut Nature Preserve. We used a non-invasive skin swabbing method to collect baseline and elevated corticosterone from paedomorph (aquatic …
Understanding Relationships Between Stress, Snake Fungal Disease, And Parasitism In Wild Cottonmouth Snake Populations, Emma Fehlker Campbell
Understanding Relationships Between Stress, Snake Fungal Disease, And Parasitism In Wild Cottonmouth Snake Populations, Emma Fehlker Campbell
Scholars Week
Chronically raised stress levels are known to correlate with decreased immune function in vertebrates, possible leading to increased susceptibility to infections including parasitism and Snake Fungal Disease (SFD). Helminth endoparasites and Hemoparasites are frequently found in wild populations but little is known about their physiological effects. Additionally, parasite infection may have interactive effects with diseases including SFD. To our knowledge few studies have assessed potential interactions between SFD and parasites in snakes. Thus, the objective of our study is to assess the individual and interactive effects of Helminth endoparasites, hemoparasites, and snake fungal disease on cottonmouth physiological stress. We are …

Holocene Records Of Nebraska Mammals, Hugh H. Genoways
Zea E-Books Collection
A survey of the archeological and paleontological literature allowed a compilation of Holocene records of mammals in Nebraska. This survey identified Holocene records from 338 sites in 62 of the 93 Nebraska counties. These counties were located throughout state, but there was a concentration of sites in southwestern Nebraska where there were 27 fossil sites in Frontier County and 22 in Harlan County. Fossils sites were underrepresented in the Sand Hills region. Records of fossil mammals covered the entire Holocene period from 13,000 years ago until AD 1850. A minimum of 57 species (with eight additional species potentially present) representing …

Phenology Of Antler Casting And Occurrence Of Late-Breeding In Nebraska White-Tailed Deer, Brian C. Peterson, Patrick D. Farrell, Dave Fehlhafer, Miranda C. Reinson, Dustin H. Ranglack
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
White-tailed deer (Odocoileus virginianus) in Nebraska primarily breed in November (stimulated by photoperiod), but this season extends into December and January for unfertilized females and healthy fawns reaching the appropriate breeding weight by winter. Variation in the typical mating period can be attributed to geographic region, skewed sex ratios, and fawns reaching sexual maturity during their first year of birth. During April of 2019, we observed late season breeding by a male white-tailed deer in the central Platte River valley and documented late antler casting for this same late-copulating male. An additional male was observed in April of …

Research Data Sets
North American Porcupines (Erethizon dorsatum) have a broad geographic distribution across much of the continent, but recent evidence suggests that their populations may be declining in some areas, including the Pacific Northwest. Estimating baseline historical and contemporary distributions of Porcupines is necessary for initiating monitoring efforts and, if necessary, informing strategic conservation actions. We compiled 1905 occurrence records of Porcupines in Washington, Oregon, and northern California from 1908 to 2018. Using maximum entropy modeling (Maxent), we created historical and contemporary distribution models based on Porcupine records from 1981–2010 and 2012–2018, respectively, to match the temporal scale of available …
