Microbial Mats In Dinosaur Ichnocoenoses, Nora Noffke, Paul C. Murphey, Roger C. Buntin, Martin G. Lockley

OES Faculty Publications

Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration. At such sites, epibenthic or endobenthic microbial mats may have developed as well and may have led to exquisite track preservation. Microbial mats in coastal, lacustrine or flood plain environments cause ‘microbially induced sedimentary structures—MISS’, which are micobialites found in sandy or evaporitic settings. The microbial structures record environmental parameters including meteorological conditions that existed at the time …

Assessing The Behavioral And Health Effects Of Turtle Racing On Eastern Box Turtles (Terrapene Carolina Carolina), Michelle Weaver

Murray State Theses and Dissertations

To make informed management decisions regarding box turtles (Terrapene spp.) and other turtle species, one must understand what influences them at multiple levels of biological organization. Common influences include the pet trade, urbanization, habitat degradation, and disease. One factor that has not been studied but could influence turtles at multiple levels of biological organization is turtle racing. It is common practice to use wild caught turtles at these events because there is a lack of regulation and enforcement. My study focused on evaluating the effects of turtle racing on eastern box turtles (Terrapene carolina carolina; hereafter EBTs) …

Gene Expression In Relation To Bone Fractures In Throughbred Racehorses, Anna M. Rauber-Ramos

Theses and Dissertations--Veterinary Science

Evidence that fractures in Thoroughbred racehorses are outcomes of chronic bone microdamage has led to extensive research into identifying horses at increased risk of fracture. This includes the use of biomarkers and messenger RNA (mRNA) as a measure of bone turnover. Previous research has found expression differences in horses with fractures compared to controls. Utilizing pre-race whole blood samples collected over an 18-month period from Thoroughbred racehorses in Southern California, RNA-sequencing was conducted on horses with bone fractures and race-matched controls to identify differences in gene expression. Focusing on third metacarpal (MC3) and proximal sesamoid bone (PSB) fractures, differentially expressed …

Age Class Is Not Related To Size Or Composition Of Home Ranges Among Suburban White-Tailed Deer During Parturition, Nathan D. Pyburn

Journal of Earth and Life Science

How white-tailed deer use the landscape in an urban environment can help us understand the effects of urbanization on deer populations. White-tailed deer form observable matriarchal hierarchies in studied populations. This study examines the matriarchal structure, home range size, and home range composition of 25 collared white-tailed deer within the city limits of Bemidji, MN. The results found no significant difference between age class and home range size or composition. However, movement metrics from yearling and mature age classes were more similar than the juvenile age class females. I propose this is because social acceptance between mature females was higher …

Exploring The Effects Of Road Salt On Earthworm Species, Alea Mry Koston

Williams Honors College, Honors Research Projects

This study examines the effects of two road salts, sodium chloride (NaCl) and calcium magnesium acetate (CMA), on the health of two earthworm species: Eisenia fetida and Lumbricus terrestris. Over a 4-week period, approximately 168 earthworms were exposed to varying concentrations of either NaCl, CMA, or mixed ratios of both, with a control group included for comparison. The experiment involved monitoring the changes in earthworm weight and measuring their contraction rates to determine physiological responses. Statistical analysis revealed no significant differences in weight or activity between NaCl and CMA treatments for either species. However, higher concentrations of NaCl resulted in …

Elongate Locomotors Show Consistent Torque Patterns Across Substrates, Spencer Bradford, Henry Astley

Williams Honors College, Honors Research Projects

The four main movements found in snakes are understood mainly due to external study; however, muscular forces and resulting torques are poorly known. The main research objective is to study the torque production on different substrates using a snakebot. The study will give a rudimentary model for torque production on different substrates. It can then be compared against biological systems to understand snake movement at a muscular level. This study used a snakebot, allowing direct assessment of the current being run through each of its motors (proportional to torque). Data was then examined using a Principal Component Analysis test for …

Assessing Intra-Seasonal Changes In Summer Elk Diet Composition, Ava E. Window

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Elk (Cervus canadensis) require adequate forage to fulfill their seasonal nutritional requirements. Elk undergo their highest nutritional demands during summer to support critical life functions such as late gestation, lactation, and juvenile growth. However, variations in plant phenology significantly influence the quality and quantity of forage available to elk during the summer season. As summer advances and plant communities mature, forage quality often declines, leading to a landscape that imposes greater nutritional constraints on elk. As a result, prior research on elk foraging habits has primarily focused on late summer. This has led to limited knowledge surrounding the …

Use Of Fecal Inoculum From Easy And Hard Keeper Horses To Determine In-Vitro Digestibility Of Feedstuffs Used In Equine Diets, Leah Bills

Graduate Theses/Dissertations

Digestibility studies provide vital information for formulating ideal diets based on an animal’s ability to digest and absorb the available nutrients from the feed provided. The purpose of this study was to determine if there is a difference in the nutrient digestion of horses between those that have a difficult time maintaining a healthy body weight (body condition score at or below 5, hard keeper) and those that easily maintain a healthy body weight (body condition score of >5, easy keeper). Six mature geldings averaging 534.1 ± 47.1 kg were used in this study. During the experimental period horses were …

Exploring Mating Patterns: The Interplay Of Genes, Environment, And Their Evolutionary Outcomes, Sanduni Talagala

Theses and Dissertations (Comprehensive)

There is great variation in the reproductive tactics exhibited both between and within different species, which is reflected in how individuals engage in mate assessment, mate choice and offspring production. It is therefore important to understand general mating patterns of populations, the factors that influence these mating patterns, and the consequences they carry, in order to get a more holistic understanding of mating systems. This doctoral research represents a multi-pronged investigation of the factors shaping mating patterns and their consequences, how environmental factors influence mating patterns, and how both genotypes and the environment interact to influence mate choice decisions and …

This review synthesizes current knowledge on farrowing performance and piglet characteristics of highly prolific sows in tropical settings. Studies have reported a consistent increase in litter size globally, leading to challenges in farrowing management and piglet survival. Factors such as elevated ambient temperatures and extended farrowing durations have …

Study Of The Brain Anatomy Of Three Extinct Marsupials: Thylacinus Cynocephalus, Thylacoleo Carnifex, And Silvabestius Johnnilandi, Francisco Garcia

Honors Program Theses and Research Projects

Marsupials are pouched mammals that today are mainly found in Australasia and South America. Marsupials have proven to be quite intriguing to evolutionary biologists who note how some marsupials resemble placentals in anatomy due to convergent evolution, with both marsupials and placentals filling similar niches in their respective environments. As of today, studies interested in marsupial brain evolution have published descriptions of cranial endocasts for several species of marsupials, with the number of descriptions seeing a massive boost over the last 20 years with the arrival of CT imaging technology. However, no comprehensive study of brain evolution in marsupials has …

Analyzing Head Morphology Trends With Increasing Population Density In A Jamaican Lizard Species, Lillian Durand

2024 Fall Honors Capstone Projects - Archive

Anolis lizards are model organisms for studying natural selection and evolutionary processes. One trait that is hypothesized to be advantageous for males is head size, as larger heads lead to stronger bite forces and increased likelihood in outcompeting other males for mates. To better understand how linked head size and intraspecific competition are, the head morphology of male A. lineatopus was analyzed among Jamaican populations with varying levels of population density. Population densities were determined using standardized plot surveys and mark resight models. Head dimensions and body condition for individual lizards were measured at each site. My study found that …

The Impact Of Wild Pigs (Sus Scrofa) On Avian Occupancy And Vegetation Structure, Kenneth Wilson

Graduate Theses and Dissertations

Invasive species, particularly wild pigs (Sus scrofa), pose a significant threat to native ecosystems through both direct and indirect impacts. Wild pigs are large-bodied omnivorous species that can consume a wide variety of plants and animals and are known for destructive foraging behaviors, which likely threatens avian communities through habitat alteration and can impact the long term structure of ecosystems where they are present.

In chapter 1, we used a combination of avian point count surveys, vegetation assessments, and camera trap surveillance to quantify how the occupancy of breeding birds in bottomland hardwood forests changed in relation to …

The Thai Journal of Veterinary Medicine

Feline hemoplasmosis is a disease with worldwide distribution, mainly in tropical countries, where its transmission is favored by the presence of vectors such as fleas and ticks. In Colombia, the diagnosis of the disease in small animals has been limited to the identification of the pathogen in blood smears, which have low sensitivity and specificity, demanding methods of higher diagnostic value, such as those based on molecular techniques. The objective of the present study was to investigate the prevalence of Mycoplasma spp. in felines from the city of Ibagué using the PCR and the associated risk factors. Briefly, blood samples …

An Assessment Of Dingo Ancestry In Camp Dogs In Western Australia, Tracey L. Kreplins, Danielle Stephens, N Laing, C Oskam

Biosecurity Research Articles

Hybridisation between Australian dingoes and domestic dogs is a controversial area of interest and research. An ongoing canine sterilisation programme in rural and remote Western Australia provided an opportunity to assess the dingo ancestry of camp dogs and opportunities for hybridisation. Blood samples were collected from 345 individual community dogs at 21 locations. Dogs were screened using 23 microsatellite loci and ancestry percentage assigned using an iterative Bayesian assignment algorithm. A single individual was a dingo, 96% were domestic dogs and 3.5% were hybrids. Camp dog and dingo hybridisation in these areas is of little concern in terms of conserving …

Managing Equine Metabolic Syndrome, Abigail Meldrum, Karl Hoopes

All Current Publications

Equine metabolic syndrome (EMS) is a relatively new disease that we are still learning about. There are many things to investigate when dealing with a new disease: causes, predispositions, symptoms, secondary issues, treatments, and prevention. Because changing the animal's feed regimen is currently the most effective and well-known way to manage EMS, this fact sheet focuses primarily on how diet can impact affected horses. As a newer syndrome, it is vital to learn as much as possible about it to understand, treat, and prevent this disease.

Assessing Comprehension And Competence In Bottlenose Dolphins (Tursiops Truncatus) On The Concept: Do Something Different, Charlotte M. Mulligan

Theses and Dissertations

Many studies have been conducted using a training paradigm based on the research of Pryor et al. (1969) wherein the participants are trained on the abstract concept: do something different. This paradigm challenges working memory and requires the participants to respond with a behavior, either previously trained or novel, which has not yet been offered within the session. The work of Braslau-Schneck (1994) expanded this concept and demonstrated the ability of dolphins to successfully complete this task in synchronized pairs, though the method of accomplishing this task remained unclear. The present research was conducted as part of a broader …

Effects Of Winter Ticks (Dermacentor Albipictus) On The Reproduction Of Utah Moose (Alces Alces Shirasi), Samuel D. Robertson

Moose (Alces alces) are the largest and only solitary members of the deer family. The species can be found across many northern regions around the world. Moose are considered to have high intrinsic, recreational and ecological value. In recent years, there have been concerns about declining moose populations in portions of the species circumpolar range. Moose in Utah (Alces alces shirasi) belong to the Shiras subspecies, which is the smallest of the four subspecies found in North America. Utah moose are the southernmost naturally occurring moose population in the world. The Utah Division of Wildlife Resources …

Information About Honey Fraud: Implications Of Information Choice For Consumer Behavior, Christopher R. Gustafson

Cornhusker Economics

The study highlights that standard research practice—exposing participants to information—may not capture what will happen outside of the lab when people have a choice about what to read, view, or do with their time. While we found that having participants read about honey fraud significantly shifted their willingness to pay for local and domestic versus imported honey, we did not find those changes when people were able to select a text to read.

The implications of these findings extend beyond the issue of honey fraud to broader contexts of food safety, nutrition, and production techniques. While people have preferences for …

Postweaning Skull Growth In Living Didelphid Marsupials: The Case Of Gracilinanus Agilis And Cryptonanus Chacoensis, Iveth A. Villalobos Guerrero, Noé U. De La Sancha

DePaul Discoveries

Ontogeny is described as the history of an organism through its lifetime including development, growth, and allometry. The ontogenetic approach in cranial dimensions has proved useful in interpreting evolutionary patterns. Among the largest Didelphidae family of Neotropical marsupials, the species of Gracilinanus agilis and Cryptonanus chacoensis are poorly known. In this study, we address three questions; Is there sexual dimorphism in these species? What is the pattern of allometry? Which allometric patterns best describe the patterns in the skull and mandible? We applied geometric morphometrics to describe and test these differences using MorphoJ. A discriminant function analysis was performed to …
