We study the phylogenetic relationships of these algae using a phylotranscriptomic data set of 76 protein-coding single-copy nuclear genes. Our data set includes novel RNAseq data for six amphibian-associated and five free-living green algae, and draft genomes of two of the latter. Within the Oophila clade (nested within Moewusinia), we find samples from two European frogs (Rana dalmatina and R. temporaria) closely related to those of the North American frog R. aurora (Oophila …
A Comparison Of Diploid And Triploid Eastern Oysters For Aquaculture Production Under Extreme Temperatures And Salinities, Joshua H. Kim
A Comparison Of Diploid And Triploid Eastern Oysters For Aquaculture Production Under Extreme Temperatures And Salinities, Joshua H. Kim
LSU Master's Theses
Off-bottom aquaculture of Eastern oysters (Crassostrea virginica) is a nascent industry that is increasingly supported by the use of triploid oysters, which grow faster than diploids. Despite their growth advantage, elevated triploid mortality compared to diploids under high temperature, low salinity, or a combination of these conditions challenge consistent triploid production. Identifying the environmental thresholds at which differential triploid mortality occurs and predicting its economic impact are important to informing decision-making in oyster aquaculture. The goal of this thesis was to compare the biological and economic performance of diploid and triploid oysters under high temperature and low salinity conditions. …

Knockdown Of Gonadotropin-Releasing Hormone Ii Receptor Impairs Ovulation Rate, Corpus Luteum Development, And Progesterone Production In Gilts, Amy T. Desaulniers, Rebecca Cederberg, Clay A. Lents, Brett White
Department of Animal Science: Faculty Publications
Reproduction is classically controlled by gonadotropin-releasing hormone (GnRH-I) and its receptor (GnRHR-I) within the brain. In pigs, a second form (GnRH-II) and its specific receptor (GnRHR-II) are also produced, with greater abundance in peripheral vs. central reproductive tissues. The binding of GnRH-II to GnRHR-II has been implicated in the autocrine/paracrine regulation of gonadal steroidogenesis rather than gonadotropin secretion. Blood samples were collected from transgenic gilts, with the ubiquitous knockdown of GnRHR-II (GnRHR-II KD; n = 8) and littermate controls (n = 7) at the onset of estrus (follicular) and 10 days later (luteal); serum concentrations of 16 steroid hormones …

Production, Purification, And Specificity Serologically Determination Of Immunoglobulin-Y (Igy) From Chicken Eggs Against Clostridium Tetani Toxoid, Kürşat Teti̇k, Bariş Sareyyüpoğlu
Turkish Journal of Veterinary & Animal Sciences
Tetanus is a life-threatening bacterial disease of humans and many animal species caused by the neurotoxin tetanospasmin (TeNT) produced by Clostridium tetani. Antitoxins obtained from horses and humans are primarily used to treat this disease. However, there are several clinical side effects and disadvantages associated with the use of these antitoxins. Current techniques for diagnosing tetanus use monoclonal antibodies produced in mice. These antibodies have several advantages, such as homogeneity and specificity. In contrast, a notable feature of polyclonal antibodies, especially egg yolk antibodies (IgYs) extracted from poultry, is that they can be generated in greater quantities than mammalian antibodies …

The Effects Of People, Time Of Day, And Season On Affiliative And Stereotypic Behaviors In Captive Rhinoptera Bonasus And Other Rays Across Two Human-Interactive Enclosures, Wren C. A. Newman
Theses and Dissertations
Cownose rays (Rhinoptera bonasus) are among the most common species found in aquaria, yet the impact of touch enclosures on their welfare remains largely unknown. While research on animal-visitor interactions has produced mixed results for other species, the lack of studies focusing on fish welfare poses a risk of overlooking potential welfare concerns. Therefore, we aimed to establish a baseline for cownose rays regarding stereotypic behaviors, sociality, and activity in captivity, and to examine the influence of human interaction on these behaviors. We collected over 700 hours of footage from two enclosures at Adventure Aquarium in Camden, NJ …
Sex Differences In The Diets Of Forest-Dwelling Baboons (Papio Anubis), Kara Hartunian
Sex Differences In The Diets Of Forest-Dwelling Baboons (Papio Anubis), Kara Hartunian
Theses and Dissertations
The ability to eat and switch between many food sources is an adaptative feeding strategy utilized for meeting nutritional needs across different environments, seasons, and physiological conditions. Baboons (genus Papio) excel at both dietary flexibility and foraging selectively, and consequently have one of the most widespread geographic distributions in the Order. To further expand to our understanding of baboon feeding ecology, I analyzed foraging activity and the nutritional characteristics of the diets of the relatively understudied rainforest baboons (Papio anubis) living in Kibale National Park, Uganda. I also investigated if there are differences in food type choice …
Maternal And Other Social Influences On Signature Whistle Structure Of A Captive Group Of Bottlenose Dolphins (Tursiops Truncatus), Riley Synan
Theses and Dissertations
Bottlenose dolphins (Tursiops truncatus) are social animals that use acoustics as a major method of communicating across a marine environment. They also live in fission-fusion groups and thus interact with many conspecifics over a lifetime. Individual dolphins have a signature whistle that functions as an identity call and serves to maintain group cohesion in murky waters or during reconciliation. Dolphins exhibit vocal learning and the signature whistle of a calf may be modeled after the whistle of their mother or another individual in the pod as they develop. Mother-calf pairs or other related animals sometimes have similar whistle types. Some …

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 …

Balancing The Scales: Evaluating Variables Of Greatest Impact To Profit Margins When Finishing Cattle, Ryan Bake
All Graduate Reports and Creative Projects, Fall 2023 to Present
This study examines the risk associated with finishing cattle in a feedlot, specifically in the context of historically high cattle prices and quality grade grid marketing systems that have not adjusted to these elevated prices. The analysis also looks at performance factors that drive profitability differences in pens of cattle in a commercial feedlot, and how market factors also impact profitability. Regression analysis determines the significance of performance variables such as days on feed, average daily gain, feed conversion rates, and carcass characteristics on pen profitability. The impact of cattle breeding and pre-feedlot management of the cattle are also considered …
