Time Series Modeling To Ascertain Age In Fisheries Management, Kathleen Sue Kirch Apr 2024

Time Series Modeling To Ascertain Age In Fisheries Management, Kathleen Sue Kirch

OES Theses and Dissertations

The ability to assign accurate ages of fish is important to fisheries management. Accurate ageing allows for the most reliable age-based models to be used to support sustainability and maximize economic benefit. Structures used to age include bones, scales, and most commonly ear bones (otoliths). Assigning age relies on validating putative annual marks by evaluating accretional material laid down in patterns in fish otoliths, typically by marginal increment analysis. These patterns often take the shape of a sawtooth wave with an abrupt drop in accretion yearly to form an annual band and are typically validated qualitatively. Researchers have shown keen …


Climate Change-Associated Declines In Water Clarity Impair Feeding By Common Loons, Walter H. Piper, Max R. Glines, Kevin C. Rose Mar 2024

Climate Change-Associated Declines In Water Clarity Impair Feeding By Common Loons, Walter H. Piper, Max R. Glines, Kevin C. Rose

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Climate change has myriad impacts on ecosystems, but the mechanisms by which it affects individual species can be difficult to pinpoint. One strategy to discover such mechanisms is to identify a specific ecological factor related to survival or reproduction and determine how that factor is affected by climate. Here we used Landsat imagery to calculate water clarity for 127 lakes in northern Wisconsin from 1995 to 2021 and thus investigate the effect of clarity on the body condition of an aquatic visual predator, the common loon (Gavia immer). In addition, we examined rainfall and temperature as potential predictors …

The Impact Of Essential Amino Acids On The Gut Microbiota Of Broiler Chickens, Thyneice Taylor-Bowden, Sarayu Bhogoju, Collins N. Khwatenge, Samuel N. Nahashon

Agricultural and Environmental Sciences Faculty Research

The research involving the beneficial aspects of amino acids being added to poultry feed pertaining to performance, growth, feed intake, and feed conversion ratio is extensive. Yet currently the effects of amino acids on the gut microbiota aren’t fully understood nor have there been many studies executed in poultry to explain the relationship between amino acids and the gut microbiota. The overall outcome of health has been linked to bird gut health due to the functionality of gastrointestinal tract (GIT) for digestion/absorption of nutrients as well as immune response. These essential functions of the GI are greatly driven by the …


Necked Keelback Fowlea Schnurrenbergeri (Kramer, 1977) In Northeastern Punjab, Pakistan, Mudassar Basri, Zohaib Nasar Mar 2024

Necked Keelback Fowlea Schnurrenbergeri (Kramer, 1977) In Northeastern Punjab, Pakistan, Mudassar Basri, Zohaib Nasar

Journal of Bioresource Management

The bar-necked keelback snake plays a vital ecological role as a natural pest controller, effectively regulating populations of fish, frogs, and rodents. Through their predatory behavior, they contribute significantly to maintaining ecological balance by managing the numbers of these smaller creatures, thereby contributing to the overall health of ecosystem. We have documented Fowlea schnurrenbergeri in the urban center of Tehsil Zafarwal and Dariyapur village, within Narowal district, Punjab. Previously, Sindh-Thatta represented the southeastern most known locality for this species in Pakistan. This study presents new insights into the distribution range of this less-frequently observed species.


Vigilance And Foraging Behaviors Of Two Sciurid Species Between College Campuses And Urban Environments, Patrick Geyer, Zoe Buffington, Lorelei E. Patrick Mar 2024

Vigilance And Foraging Behaviors Of Two Sciurid Species Between College Campuses And Urban Environments, Patrick Geyer, Zoe Buffington, Lorelei E. Patrick

SACAD: Scholarly Activities

A comparison between the extent that sciurid specimens display vigilance and foraging behaviors on college campuses against specimens within urban environments. Observations of fox squirrels and western gray squirrels were taken from the Squirrel-Net behavioral database used for this project. We found there was a significant difference between the percent vigilance behaviors and foraging behaviors on college campuses compared to urban environments. This suggests that squirrels residing on college campuses are more desensitized to pedestrian activity and foot traffic compared to squirrels that inhabit urban areas.

Effectiveness Of Frog Skin Secretions Against Uv-B Radiation, Connor Mcgaha, Kinkade Mcmurray, Lee B. Kats Mar 2024

Effectiveness Of Frog Skin Secretions Against Uv-B Radiation, Connor Mcgaha, Kinkade Mcmurray, Lee B. Kats

Seaver College Research And Scholarly Achievement Symposium

As an increasing number of their species face possible extinction, amphibian populations have been steadily declining over the past decades (IUCN). While various factors have been suggested or proven to be partially responsible for this reduction, increased ultraviolet B radiation (UVBR) appears to be one of the more prominent explanations, especially when considering the continual thinning of the Earth’s ozone layer due to anthropogenic climate change. However, it has also been discovered that skin secretions, which are reported to function as a component of amphibians’ innate immune systems, may have an effect on UVBR (Cramp and Franklin). With this in …

Using Arbuscular Mycorrhizal Fungi To Help Establish And Increase Vigor Of Plants In Mineland Soils, Melissa Burrell, Brad Geary, Shannon Nelson, Josh Moroni De Santiago Lazalde, Scott Kent, Matthew Madsen

Library/Life Sciences Undergraduate Poster Competition 2024

  • Vegetation establishment in areas impacted by mining can be difficult due to a lack of beneficial soil microbes.
  • The introduction of soil mutualists, such as arbuscular mycorrhizal fungi (AMF), may improve mineland revegetation efforts. AMF forms a mutually beneficial relationship with plants to aid in nutrient absorption and improve water uptake.
  • Practitioners commonly need to decide where to source their AMF. Locally collected AMF requires effort to collect and process, but this source should be adapted to the restoration site. Commercial products are easy to obtain, but their strains may not be suitable for the environment they are being placed …

Interior Least Terns (Sternula Antillarum Athalassos) In A Landscape Of Fear: Explaining Predator Frequency On Sandbars Using Habitat Features, Carice N. Kimbrell Mar 2024

Interior Least Terns (Sternula Antillarum Athalassos) In A Landscape Of Fear: Explaining Predator Frequency On Sandbars Using Habitat Features, Carice N. Kimbrell

ATU Theses and Dissertations 2021 - Present

Causes of colony failure in interior least terns (Sternula antillarum athalassos) have been a prevalent topic for researchers investigating this previously endangered species. In Arkansas, these colonies are primarily located on sandbars formed along the McClellan-Kerr Arkansas River Navigation System. Reduction in nesting site quality may put this sensitive species at a greater risk for predator encounters. In my first chapter, I identified which sandbar characteristics resulted in higher frequencies of predator encounters at interior least tern colonies. In my second chapter, I investigated how those predators influenced colony production and whether interior least tern colonies exhibited similar …


Daily Injection Of The Β2 Adrenergic Agonist Clenbuterol Improved Muscle Glucose Metabolism, Glucose-Stimulated Insulin Secretion, And Hyperlipidemia In Juvenile Lambs Following Heat-Stress-Induced Intrauterine Growth Restriction, Rachel L.

Daily Injection Of The Β2 Adrenergic Agonist Clenbuterol Improved Muscle Glucose Metabolism, Glucose-Stimulated Insulin Secretion, And Hyperlipidemia In Juvenile Lambs Following Heat-Stress-Induced Intrauterine Growth Restriction, Rachel L. Gibbs, James Wilson, Rebecca M. Swanson, Joslyn K. Beard, Zena M. Hicks, Haley Beer, Eileen Marks-Nelson, Ty B. Schmidt, Jessica Lynn Petersen, Dustin T. Yates

Department of Animal Science: Faculty Publications

Stress-induced fetal programming diminishes β2 adrenergic tone, which coincides with intrauterine growth restriction (IUGR) and lifelong metabolic dysfunction. We determined if stimulating β2 adrenergic activity in IUGR-born lambs would improve metabolic outcomes. IUGR lambs that received daily injections of saline or the β2 agonist clenbuterol from birth to 60 days were compared with controls from pair-fed thermoneutral pregnancies. As juveniles, IUGR lambs exhibited systemic inflammation and robust metabolic dysfunction, including greater (p < 0.05) circulating TNF, IL-6, and non-esterified fatty acids, increased (p < 0.05) intramuscular glycogen, reduced (p < 0.05) circulating IGF-1, hindlimb blood flow, glucose-stimulated insulin secretion, and muscle glucose oxidation. Daily clenbuterol fully recovered (p < 0.05) circulating TNF, IL-6, and nonesterified fatty acids, hindlimb blood flow, muscle glucose oxidation, and intramuscular glycogen. Glucose-stimulated insulin secretion was partially recovered (p < 0.05) in clenbuterol-treated IUGR lambs, but circulating IGF-1 was not improved. Circulating triglycerides and HDL cholesterol were elevated (p < 0.05) in clenbuterol-treated IUGR lambs, despite being normal in untreated IUGR lambs. We conclude that deficient β2 adrenergic regulation is a primary mechanism for several components of metabolic dysfunction in IUGR-born offspring and thus represents a potential therapeutic target for improving metabolic outcomes. Moreover, benefits from the β2 agonist were likely complemented by its suppression of IUGR-associated inflammation.

Inbreeding Tolerance In Two Isolated Populations Of Harting’S Vole Microtus Hartingi(Rodentia, Arvicolinae), Tanya Zorenko, Larisa Petra Kaija Mar 2024

Inbreeding Tolerance In Two Isolated Populations Of Harting’S Vole Microtus Hartingi(Rodentia, Arvicolinae), Tanya Zorenko, Larisa Petra Kaija

Turkish Journal of Zoology

The adaptive effects of inbreeding are understudied, but accumulating evidence suggests that it plays a major adaptive role in speciation, as populations with a history of inbreeding are more prone to it. Differences in inbreeding tolerance in two populations of Microtus hartingi voles were studied through a series of experiments on reproductive behaviour and partner choice. Modelling an artificial polygyny via the formation of trios composed of a brother, sister, and an unrelated female has shown an uneven attitude towards inbreeding, which was closely linked to the reproduction strategy: voles of the Rhodopean population (RP) would reproduce communally with only …
