A Redescription Of Leiurus Libycus (Birula, 1908), Stat. N. (Scorpiones: Buthidae), Ersen A. Yağmur, František Kovařík, Victor Fet

Euscorpius

Buthus quinquestriatus libycus was described by Birula (1908) from the Libyan Desert, based on a subadult male specimen. This taxon was later synonymized with Leiurus quinquestriatus (Ehrenberg, 1828) by Vachon (1949). In this study, we re-evaluate this taxon and recognize it as Leiurus libycus (Birula, 1908), stat. n., providing a redescription based on the holotype. The type locality of this species is clarified as western Egypt (between Alexandria and Fayum). We synonymize Leiurus aegyptiacus Lourenço & El-Hennawy, 2021 with L. libycus, stat. n., syn. n.

Data From: The Dynamic Responses Of The Mouse Gut Microbiome To Dietary Supplementation With Various Anthocyanin-Rich Foods In The Context Of A Western Diet, Abby D. Benninghoff

Browse all Datasets

Background/Objectives: Anthocyanin (ACN)-rich foods may support gut health by modulating the microbiome and reducing inflammation, potentially lowering the risk of colitis-associated colorectal cancer. However, the dynamic response of the gut microbiome to ACN-rich diets is not well characterized, including in the context of structural and compositional differences among ACN-containing foods. This study examined the temporal response of the mouse gut microbiome to dietary ACNs, focusing on the impact of structural variation. We hypothesized that microbiome shifts would occur rapidly but require sustained dietary ACN intake to persist. Methods: C57BL/6J mice were fed the total Western diet (TWD) supplemented with freeze-dried …

Passive Integrated Transponders: An Effective Marking Technique For Individual Identification Of Anaxyrus Fowleri?, Emily Leprell

Honors College Theses

With the rise of fungal disease such as Chytridiomycosis, known as chytrid, causing massive population declines for many species of frogs and toads (order Anura), specific conservation strategies are needed now more than ever. In many cases, being able to mark and identify individuals is a necessary step in developing an effective conservation plan. Individual identification allows researchers to obtain accurate population estimates, which are needed to test the progress and validity of conservation management decisions. However, due to their unique life history, including cutaneous respiration and a dichotomous lifestyle, anurans are among the most difficult wildlife species to …

Drinking Behavior And Performance In Neonatal Swine, Yasmine Taylor

Honors Theses

This behavioral study analyzes the relationship between water intake and growth performance in pre-weaned piglets. Growth is paramount in pork production, and maximizing growth in weaned piglets has been thoroughly researched. However, one crucial aspect of growth is often overlooked: water, especially in neonatal piglets. Therefore, this study aimed to determine if there is a positive relationship between water intake and performance in pre-weaned piglets by observing different behaviors. Weights were recorded at birth, after 7-10 days, and at weaning. Piglets were observed three times a day, in the morning, afternoon, and evening, for 21 days via scan sampling. Observation …

How Aza Zoos And Aquariums Are Helping To Fill The Gap, Erika Bauer, Grace Fuller, Candice Dorsey

Animal Sentience

Oldfield & Bonano (2024) identify significant gaps in scientific knowledge about certain animal taxa, such as reptiles, amphibians, invertebrates, and fish. Despite some efforts, published literature remains limited, forcing decision-makers to rely more on experiential knowledge than scientific evidence. AZA-accredited zoos and aquariums are uniquely positioned to bridge these gaps and advance animal welfare science by fostering collaboration, building partnerships, and promoting multi-disciplinary approaches to welfare assessments.

Ammonia Production From Cattle At The Walter C. Todd Agricultural Research Center, Sydney Cunningham, Elizabeth Smith, Rachel Nelson, Brayden Wagner

Undergraduate Research Conference

The Walter C. Todd Agricultural Research Center cattle pen was tested to measure the ammonia emission rates produced by cattle. Samples were collected from six testing locations. Eighteen samples were taken across three days of testing, in 8-hour increments. We found that small-scale cattle in open-air pens produce minimal amounts of ammonia that are not a concern for air quality. Ammonia was detectable in small quantities in the testing sites adjacent to the cattle and not in locations more than 0.1 miles away.

Advantages, Disadvantages, And Factors Influencing The Reproductive Performance Of Gilts And Sows Raised In Gestational Group Housing And Free-Farrowing Systems, Natchanon Dumniem Dr., Thomas D. Parsons, Padet Tummaruk

The Thai Journal of Veterinary Medicine

In the modern global pig industry, there is a growing interest in animal-friendly agriculture, encouraging farmers to prioritize humane practices and meet the welfare needs of their animals. In developed countries, consumers are increasingly concerned about animal welfare, particularly regarding pigs as social animals, advocating for their housing in groups that reflect their natural behaviors in the wild. There is significant societal pressure to eliminate the use of crate systems, which cause discomfort to animals in commercial farming. In these systems, breeding females are often restricted in movement throughout the reproductive cycle. As a result, alternative husbandry and housing systems …

Adaptation Of Influenza A Virus Strains A/Anhui/1/2013 (H7n9) And A/Shanghai/1/2013 (H7n9) For Development Of Effective Mouse Models, Spencer Mullen

Student Research Symposium

Introduction

Animal models are key to the research and development of antiviral interventions. Two strains of low-pathogenic avian influenza virus, A/Anhui/1/2013 and A/Shanghai/1/2013 (H7N9), isolated from a 2013 outbreak in China and acquired by USU’s Institute for Antiviral Research from the CDC, are the subject of this project.

Developing antiviral interventions against Influenza A H7N9 is essential because:

• Global outbreaks have caused high mortality among bird and human populations since 2013.^[1]

• Low-pathogenic avian flu viruses can mutate to become highly pathogenic.^[2]

• No current prophylactic or therapeutic human interventions exist.^[3]

Establishing Methods For In Vitro Static Culture Of Gut Microbiomes For Nutritional Intervention Studies, Jeremy Case

Student Research Symposium

The National Cancer Institute reports colorectal cancer as the leading cause of cancer death for individuals under 50 in the United States (American Cancer Society). These rates continue to rise with poor diet, microbiome dysbiosis, and gut inflammation being the primary drivers.

Our lab performs nutrient- intervention studies on DSS/AOM colitis-induced mouse models fed the total Western diet, reflective of the average American’s diet. A poor diet promotes gut microbiome dysbiosis and subsequent colitis, ultimately yielding colon cancer. We seek to understand how the introduction of a bioactive compound may lessen or promote these effects in in vivo mouse models. …

Exercise And Its Effect On The Nad Content Of Tissues In Niacin Deficient Mice With Free Choice Running Wheels, Stellaluna Star

Student Research Symposium

Nicotinamide adenine dinucleotide (NAD) content of tissues decreases over time during aging. In our study, we determine if physical exercise has an effect on the NAD content in tissues of transgenic mice that were NAD- deficient because of vitamin B3-free diet. The underlying hypothesis of this study is that exercise can prevent NAD decline and maintain higher level of NAD in tissue. A potential impact of this study is that exercise could be used to lengthen healthspan compared to individuals not participating in any physical exercise.

Conventional poultry management techniques are failing to meet increased demand for poultry products as the population continues to grow. As a result, this issue has become a major concern for small-scale farmers, particularly those in low-income areas, in terms of food security. One of the main reasons for this is that the farmers rely on intensive farming methods which are inefficient for automating daily poultry operations. However, intensive farming methods pose major environmental concerns to ecosystems and poultry health. Also, the environmental conditions, welfare, and productivity of poultry operations may be harmed by the global climate crisis and poultry waste …
