Laboratory Mice Burrowing Responses To Predator Calls, Katie Vonderembse, Brianna Graber, Molly Seeberger Apr 2019

Laboratory Mice Burrowing Responses To Predator Calls, Katie Vonderembse, Brianna Graber, Molly Seeberger

Student Symposium

The avoidance of predation is an essential trait in mice and depends on the ability of the mouse to recognize its predators. It is predicted that the calls of predators act as stimuli which signal the presence of potential danger. Laboratory mice have been shown to respond with defensive behaviors, such as burrowing, when exposed to the the calls of predators. To test how mice respond to different predator calls, we will play the sounds of three owls, Eastern Screech Owl,Tawny Owl, and American Barn Owl, and look at burrowing behaviors. Human voices reading a book will be used ...


Characterization Of The Yeast Gene Ydl218w: A Role In Cell Wall Biosynthesis And Maintenance?, Kaden Hubly Apr 2019

Characterization Of The Yeast Gene Ydl218w: A Role In Cell Wall Biosynthesis And Maintenance?, Kaden Hubly

Student Symposium

The budding yeast, Saccharomyces cerevisiae, is a common model organism used to study eukaryotic cell biology. S. cerevisiae is a fungus with a cell wall which makes it an excellent model for the study of antifungal agents. There are close to 1,000 genes of unknown function (GUFs) in S. cerevisiae. One of these is the gene YDL218W on which our research is focused. While little is known about this gene, evidence suggests that it may be involved in cell wall synthesis or maintenance. For example, YDL218W is induced by a transcription factor known to regulate genes involved in maintaining ...


Betta Fish Reactions To Color: A Qualitative And Quantitative Analysis, Jessica Barrios, Jackie Arnott Apr 2019

Betta Fish Reactions To Color: A Qualitative And Quantitative Analysis, Jessica Barrios, Jackie Arnott

Student Symposium

We will be studying the connections between mating, aggression, and the coloration of male betta fish and how they react to the coloration of other betta fish. We chose this topic because coloration is genetically linked to aggression in male betta fish, and because aggressive behaviors are very similar to mating behaviors.


Flight And Wing Comparison Of Bats In A Cloud And A Dry Forest In Costa Rica, Makali Haines Apr 2019

Flight And Wing Comparison Of Bats In A Cloud And A Dry Forest In Costa Rica, Makali Haines

Student Symposium

The shape, and size of an object’s wings and body can tell you a lot about their aerodynamics and strategies for flight. Some wings are built to be fast and agile while others are slower but more powerful, and there are a lot of factors that go into deciding the best strategy for each situation or location. When you think of this in terms of animals' wings and different habitats one might predict that different habitats contain animals that have different flying strategies. I measured many aspects of Costa Rican bats caught in both the wet and dry forest ...


Human Music Genre Recognition In Goldfish, Makali Haines, Sophia Hallam Apr 2019

Human Music Genre Recognition In Goldfish, Makali Haines, Sophia Hallam

Student Symposium

Music plays a big role in our daily lives, but when it comes to the animal world many species don’t react to our music, but that’s not to say they can’t react. In a previous study by scientists at Israeli Technion Institute of Technology and lead by Kazutaka Shinozuka in 2013 goldfish didn’t show a preference towards an example of our music but rather they showed and discrimination and avoidance to one. From that we hypothesized that goldfish could be trained to discriminate human made music genres from certain sound cues. The goldfishes’ tests did not ...


Advancing Natural History Research Using The Collections Of The Owu Brant Museum Of Zoology, Josh Pletcher, Kyle Davis Apr 2019

Advancing Natural History Research Using The Collections Of The Owu Brant Museum Of Zoology, Josh Pletcher, Kyle Davis

Student Symposium

Natural history collections are important repositories of biological and geological material. Biological collections provide raw data to interpret the ecology, anatomy, and evolution of living and fossil organisms. OWU’s zoological collections play an important role in undergraduate research and educating future preparators. Two projects are currently in progress: Kyle Davis’ work on size variation in house sparrows and Josh Pletcher’s work digitizing OWU’s collection of Ward’s fossil casts. We travelled to museums in New York and Connecticut to further pursue our research. Kyle Davis’ research focuses on Bergmann’s Rule, which states that as temperature decreases ...


Studying The Social Behavior And Preferences Of Polar Bears At The Columbus Zoo And Aquarium, Molly Seeberger Apr 2019

Studying The Social Behavior And Preferences Of Polar Bears At The Columbus Zoo And Aquarium, Molly Seeberger

Student Symposium

Polar bears (Ursus maritimus) are relatively solitary animals unless it is breeding season. At the Columbus Zoo and Aquarium, the polar bears participate in the Species Survival Plan where breeding for conservation efforts is encouraged. Lee, an 19-year-old male, came to the Columbus Zoo and Aquarium in the Fall of 2018 in hopes of breeding with 12-year-old twin females Aurora and Anana. Because Lee’s previous experience was only living with one female, I wanted to observe whether he would prefer a particular female because he now had two females to choose from. Not only did I look for preference ...


Investigating Crayfish (Orconectes Rusticus) Aggression And How It Varies With Resource Availability, Allie Smith, Rebecca Lipster Apr 2019

Investigating Crayfish (Orconectes Rusticus) Aggression And How It Varies With Resource Availability, Allie Smith, Rebecca Lipster

Student Symposium

Animals that express agonistic behavior toward one another are prone to recognizing hierarchical status among individuals. Recognizing status has proven to be evolutionarily advantageous for crayfish (Orconectes rusticus) because it allows dominant individuals to maximize resources and permits subordinate individuals to steer clear of potentially costly battles. More specifically, two crayfish experiencing aggression can generally determine who the dominant and subordinate individuals are in a fight. A higher social status within a social hierarchy can allow for increased access to differing resources, such as food, mates, and shelter. In this experiment, we want to see if limiting resources will affect ...


Size Increase With Altitude In The Rufous-Collared Sparrow (Zonotrichia Capensis), Kyle Davis Apr 2019

Size Increase With Altitude In The Rufous-Collared Sparrow (Zonotrichia Capensis), Kyle Davis

Student Symposium

Heat is generated by the body volume and lost across its surface. Therefore larger homeotherms with their proportionately larger volume and smaller surface area will withstand cold better than small homeotherms, which has been addressed in some basic ecological principles. Bergmann’s Rule indicates that organisms at higher latitudes (and therefore lower temperatures) will be larger than those at lower latitudes, and Allen’s Rule indicates that appendage size is generally smaller in cooler temperatures. Both Bergmann’s and Allen’s rules relate body size to latitude and/or temperature, but environmental temperature also changes with altitude. We tested the ...

Dominance And Aggression Among Hummingbirds In The Cloud Forests Of The Talamanca Mountains, Costa Rica, Crystal Sauder, Aileen Scarim Apr 2019

Dominance And Aggression Among Hummingbirds In The Cloud Forests Of The Talamanca Mountains, Costa Rica, Crystal Sauder, Aileen Scarim

Scholar Week 2016 - present

Hummingbirds (Trochilidae) are known for being aggressive and territorial. By knowing hummingbirds are not very social, nor appear to enjoy having interactions with others, we wanted to observe how multiple species of Trochilidae interact with one another. The study was completed to observe if males of different Trochilidae would be more aggressive at hummingbird feeders over females. Three different feeder locations were decided on, spread across the Savegre Valley region near the Quetzal Education Research Center (QERC). Symbols were agreed upon in order to shorthand the exact series of events that were happening while we observed the feeders. Species and ...


Food Preferences Of Red-Headed Woodpeckers (Melanerpes Erythrocephalus) And The Relationship With Season Change, Crystal Sauder Apr 2019

Food Preferences Of Red-Headed Woodpeckers (Melanerpes Erythrocephalus) And The Relationship With Season Change, Crystal Sauder

Scholar Week 2016 - present

Red-headed woodpeckers (Melanerpes erythrocephalus) used to be easy to find out in the wild, but as humans encroached on their habitats, their populations started to become impacted. They have a habitat range from Southern Canada down to the Gulf Coast. In several states their numbers are threatened due to loss of habitat. Red-headed woodpeckers prefer to live in open woodlands with dead, or dying, trees to nest in. As humans take away the dead trees from the forests, red-headed woodpeckers are losing their nesting sites. Preservation of red-headed woodpecker habitats are needed to ensure the population starts to grow, and ...

Climate Change is the significant long term changes in the weather and temperatures on a large scale and is seen globally. Scientists have been studying the effects of Climate Change on the planet for decades; foreseeing problems of the future. Global Warming has been escalating over the past hundred years with the amount of Carbon Dioxide gases rising into to atmosphere at an alarming rate. Agri-Science Educators across Kentucky are teaching the topics of Climate Change and Global Warming and this research intends to find the truth and variances in their knowledge. Twenty educators from across the state of Kentucky ...


Impact Of Intrinsic Physiological Factors In The Population Recovery Of Myotis Lucifugus (Little Brown Myotis) From White-Nose Syndrome, Caroline Burke, Caitlin Looney, Alissah Sillah, Christopher Richardson Mar 2019

Impact Of Intrinsic Physiological Factors In The Population Recovery Of Myotis Lucifugus (Little Brown Myotis) From White-Nose Syndrome, Caroline Burke, Caitlin Looney, Alissah Sillah, Christopher Richardson

Lesley University Community of Scholars Day

White-nose Syndrome (WNS) has decimated populations of hibernating bats in the US. In particular, Myotis lucifugus (little brown myotis) has been one of the most affected. We investigated the energetic cost of innate immune response and Pseudogymnoascus destructans (Pd) fungal activity on post-hibernating little brown myotis and the link with the recovery of local populations in New England from WNS. We captured bats at one of each of 4 colonies in Eastern Massachusetts and Southern New Hampshire, consecutively, every 14 days to minimize disturbance to the colony. Blood samples were collected from each bat. Respirometry trials were performed on each ...


Courtship Behavior, Communication, And Copulation In Tigrosa Annexa, Samuel White Nov 2018

Courtship Behavior, Communication, And Copulation In Tigrosa Annexa, Samuel White

Scholars Week

The evolution of multimodal communication, where signalers use multiple signal components in multiple sensory modalities, has become the subject of investigation by many researchers. Signaling puts males at risk of predation, so why do males of some species evolve extra signals that may increase this risk? In some wolf spider species, males incorporate many visual and vibrational signals into a display that they use to attract a female for mating. Female spiders are often aggressive toward courting males and so the male display also functions to decrease the odds of cannibalism. Female wandering spiders deposit silk containing pheromones that communicate ...


Alternative Genes For Exploring Ranavirus Phylogenetics: Four Core Genes Compared To The Major Capsid Protein And The Whole Genome., Abigale Garner Nov 2018

Alternative Genes For Exploring Ranavirus Phylogenetics: Four Core Genes Compared To The Major Capsid Protein And The Whole Genome., Abigale Garner

Georgia Undergraduate Research Conference (GURC)

The Iridoviridae is a family of virus that infects invertebrates and poikilothermic vertebrates such as amphibians, reptiles, and fish. Ranavirus is one of the five genera within the Iridoviridae. Ranavirus infections have been seen on every continent. The ranaviruses have 26 core genes, but our study focuses on the utility of: an immediate early protein ICP-46 [open reading frame (ORF) 91R in Frog virus 3 (FV3)]; a transcription elongation factor TIIS (ORF 81R in FV3); Evrl/Air family protein (ORF 88R in FV3); and a hypothetical/putative protein of unknown function (ORF 94R in FV3) as alternative genes for phylogenetic ...

Further Investigation Of A Novel Rhabditid Nematode, Evan Hudgens, Nathan Schmidt Apr 2018

Further Investigation Of A Novel Rhabditid Nematode, Evan Hudgens, Nathan Schmidt

Student Symposium

Nematodes are among the most numerous and widespread animals on earth. The nematode Caenorhabditis elegans is a well-established model organism used for a wide-variety of studies ranging from biomedical to behavioral to ecological, and more. While C. elegans is well characterized, there are thousands of different species of nematodes, many of which have not been studied. We are characterizing several Rhabditid nematodes isolated in association with millipedes from both Ohio and Florida. Sequence analysis of rDNA genes supports that one of the species of worms we isolated is Oscheius myriophila. Other worms we isolated are similar, but we believe may ...


Costa Rican Moth (Lepidoptera) Wing Coloration Diversity At Ultraviolet And Incandescent Lights, Claire Thiele Apr 2018

Costa Rican Moth (Lepidoptera) Wing Coloration Diversity At Ultraviolet And Incandescent Lights, Claire Thiele

Undergraduate Research Symposium

Suitable conditions of increased precipitation and temperatures bring high biodiversity to the tropics. There are around 160,000 species of moths worldwide with new species constantly being found. Lepidoptera are essential for ecosystem management via pollination, decomposition, and nutrient cycling. It has been argued that natural selection shapes the evolution of camouflage as an anti-predator defense. It is currently controversial whether crypsis and disruptive coloration are alternative mechanisms of camouflage or whether they are interrelated anti-predator defenses. Disruptively colored prey is characterized by highly contrasting patterns to conceal the body shape, whereas cryptic prey minimizes the contrasts to background. This ...


Soil Responses To 48 Years Of Continuous No Till And Conventional Till Corn In Central Kentucky, Usa, Emily Cook Apr 2018

Soil Responses To 48 Years Of Continuous No Till And Conventional Till Corn In Central Kentucky, Usa, Emily Cook

Scholars Week

Cropping systems, fertilizer applications and tillage practices influence soil physical and chemical characteristics. In this study, the impact of long-term conventional and no-tillage systems on selected soil properties were evaluated in a continuous corn system on a Maury silt loam soil. This field for the study is located on the University of Kentucky's Research Farm (Spindletop Farm). The field was tilled in 1969 from bluegrass sod and the first year's data was in 1970. Each plot is 20 ft. by 40 ft. and for many years each plot was split with winter cover crop planted to rye or ...


Emergence Of Zoos In The U.S. And A Search For The Exotic, Austin M. Hutchinson Apr 2018

Emergence Of Zoos In The U.S. And A Search For The Exotic, Austin M. Hutchinson

Student Scholar Showcase

The emergence of zoos in twentieth century America had many factors that contributed to their mission, success, and overall exotic nature. Zoos have been a part of human civilization for centuries, but it would not be until 1876 when the first zoo would appear in the United States. Individuals craved excitement and the use of exotic animals from all over the world became an important component of what zoos would become. This era coincides with the European colonization of Sub-Saharan Africa, known as the Scramble for Africa. Animals were brought from the so-called “Dark Continent” to be put on display ...

Expanding Access To Biodiversity Literature, Patrick Randall May 2017

Expanding Access To Biodiversity Literature, Patrick Randall

Digital Initiatives Symposium

Expanding Access to Biodiversity Literature (EABL) is an IMLS-funded grant designed to enhance the collection of the Biodiversity Heritage Library (BHL), a digital library providing open access to over 50 million pages of legacy biodiversity literature.

BHL's collection is built on the digitized holdings of its member libraries, typically large research universities, natural history museums, and other well-funded organizations. EABL, however, solicits content outside the BHL consortium; small organizations that often lack the resources for cataloging and digitization nevertheless have valuable and unique literature to contribute. This has created new challenges for BHL workflows, as well as opportunities for ...


Influence Of Sex And Ambient Temperature On Asian Elephant (Elephas Maximus) Dusting Behavior, Kelly Summers Apr 2017

Influence Of Sex And Ambient Temperature On Asian Elephant (Elephas Maximus) Dusting Behavior, Kelly Summers

Student Symposium

Previous studies indicate that elephant dusting behavior can be promoted by several factors including environmental temperature and social interaction. We hypothesized that (1) if dusting serves as a voluntary thermoregulatory function, then increased ambient temperature would result in increased dusting performance, and (2) if dusting is influenced by social interactions, then male and female elephants will exhibit dusting at similar rates in a group setting. Preliminary data indicated no significant relationship between temperature and the rate of dustings performed. Contrary to our predictions, females exhibited a greater rate of dusting than males in a social environment. The current study reexamines ...


Anthropogenic Influences On Raccoon Problem-Solving Characteristics, Anarose M. Hebein Apr 2017

Anthropogenic Influences On Raccoon Problem-Solving Characteristics, Anarose M. Hebein

Honors Projects and Posters

Considered generalists, raccoons are extremely adaptable and often regarded as nuisances due to their tendency to scavenge in dumpsters and garbage cans. Because the relationship between humans and raccoons is not unilateral, it is important to study the effect human-dominated environments have on raccoon ecology. In order to better understand these anthropogenic influences, raccoon problem-solving characteristics were evaluated in both suburban and natural settings. To do this, baited puzzle boxes were provided to the raccoons and motion-activated cameras were set to record any disturbance. The study found that raccoons from the natural site solved the food puzzles in fewer nights ...

Microstructures Produced By Hadrosaur Bones From Alaska And Wyoming, Mark P. Guilliams, Samantha J. Lefaive, Michael D. Sprague Apr 2016

Microstructures Produced By Hadrosaur Bones From Alaska And Wyoming, Mark P. Guilliams, Samantha J. Lefaive, Michael D. Sprague

The Research and Scholarship Symposium

Since 2005 when Dr. Mary Schweitzer made the first discovery, microstructures with the appearance of “osteocytes” and “blood vessels” have been recovered from fossils of various localities, dating back as far as the Triassic. The majority of these finds have come from dense, cortical bone but recently have been discovered in cancellous bone. Since her initial discovery, Schweitzer has done a lot of work to verify that these microstructures are not biofilms, but instead are original organic tissue. This project was looking to get similar results to Schweitzer’s research and to find a simple test method for the initial ...


Phenotypic Variation In The Model Organism, Danio Rerio, Rachel D. Champaigne, Kim H. Brown May 2014

Phenotypic Variation In The Model Organism, Danio Rerio, Rachel D. Champaigne, Kim H. Brown

Student Research Symposium

Model organisms are used to study evolutionary conserved traits. Zebrafish (Danio rerio) are used a model organism because of their highly fecundity, external fertilization, and robust nature, making them highly adaptable to environmental and genetic variation. In an effort to limit data variation that lies outside of topic interest, phenotypic measures of variation must be performed, understood, and taken into consideration for future studies. A common measurement of phenotypic variation in fish is in the maximum (Ucrit) swimming speeds. Inter and intra-strain variation in zebrafish Ucrit swimming speeds will be observed in a swim tunnel. Baseline values will be recorded ...
