Noteworthy Natural History Notes From The Neotropics, R. Kannan

Journal of the Arkansas Academy of Science

I report some rarely observed, infrequently reported, or hitherto unrecorded ecological interactions from the neotropics. These anecdotal observations were made opportunistically during nature tours or tropical biology classes in Belize, Panama, Costa Rica, and Trinidad & Tobago, between 2014 and 2024.

Sperm Morphology In The Eastern Narrow-Mouthed Frog, Gastrophryne Carolinensis (Anura: Microhylidae), S. E. Trauth

Journal of the Arkansas Academy of Science

Studies by Scheltinga et al. (2002) and Scheltinga and Jamieson (2003) provide the most comprehensive analysis and only review of sperm morphology in Narrow-Mouthed Frogs (family Microhylidae). Of the 490+ species known to occur in this anuran family (Vitt and Caldwell 2014), only 3 are distributed in the United States (Powell et al. 2016), and 2 of these occur in Arkansas (Trauth et al. 2004). Surprisingly, sperm studies on only 12 microhylid species have been conducted (Scheltinga and Jamieson 2003), and no sperm studies are available on any North American species.

Investigating Quinclorac Binding To Human Serum Albumin Using Spectroscopy And Molecular Docking, Le Nguyen, L. Hicks, L. Jodoin, S. Carby, D. S. Sanford, D. Benavides, A. Mishra, R. Yadav

Journal of the Arkansas Academy of Science

Human serum albumin (HSA) is the most abundant plasma protein and serves as a major transporter and reservoir for a wide range of endogenous ligands, including fatty acids, heme, bilirubin, prostaglandins, and metal ions, as well as numerous exogenous compounds, such as pharmaceuticals. HSA is a 66 kDa monomeric, multidomain protein containing two principal ligand-binding sites, Sudlow sites I and II. Sudlow site I contains Trp214, the sole tryptophan residue in HSA, whose intrinsic fluorescence provides a sensitive probe for studying ligand–protein interactions.

In this study, the interaction between HSA and the persistent organochlorine herbicide quinclorac (QNC) was investigated using …

History And Distribution Of The Dark Ibises (Glossy Ibis Plegadis Falcinellus And White-Faced Ibis P. Chihi) In Arkansas, R. Tumlison, P. D. Rodriguez

Journal of the Arkansas Academy of Science

The Glossy Ibis (Plegadis falcinellus) and White-faced Ibis (P. chihi) sometimes are reported simply as Dark Ibises due to difficulty in identifying them when mature characters are not clearly visible. We evaluated reports verified on citizen science websites to examine the origins and distributions of these migratory species in Arkansas. The Glossy Ibis was first documented in Arkansas in 1956, has been reported in 21 of our 75 counties, and is found more commonly in eastern Arkansas. The White-faced Ibis was first reported in Arkansas in 1971, has been reported in 41 of our 75 counties, …

History And Distribution Of Great-Tailed Grackles (Quiscalus Mexicanus) In Arkansas, R. Tumlison, V. Andersen

Journal of the Arkansas Academy of Science

Great-tailed Grackles (Quiscalus mexicanus) were reported first in southwestern Arkansas in 1969, were nesting there in 1977, and established a resident population by 1980. Nesting was reported in far northwestern Arkansas in 1986. Presently, the species is known from 44 of Arkansas’s 75 counties, those mostly in the western and central counties. Most individuals appear to be migratory, with most reports occurring in April and May. However, breeding and now resident populations have been reported in the southwestern, northwestern, and central counties, particularly in urban areas. Birds are very commonly reported to forage at fast-food establishments and truck …

Binucleation And Seasonal Cycle Of Sertoli Cells In The Western Lesser Siren, Siren Nettingi (Caudata: Sirenidae), S. E. Trauth

Journal of the Arkansas Academy of Science

I examined binucleation and the seasonal cycle of Sertoli cells in the Western Siren (Siren nettingi) using light microscopy and transmission electron microscopy. My primary objective in this study was to report, for the first time, the presence of double nuclei in Sertoli cells in a salamander. This study also represents the sixth contribution in a series of investigations that highlight the novel nature of all aspects of spermatogenesis in this unique salamander. My findings add to a growing list of extraordinary morphological and reproductive features that distinguish this salamander from all other vertebrates.

Testing The Accuracy Of A Bear-Tracking Satellite Transmitter Collar Under Natural Conditions, K. A. Watson, K. Phipps, C. Drexler, C. R. Middaugh, M. Means, M. Hooks

Journal of the Arkansas Academy of Science

The Arkansas Game and Fish Commission tracks American black bears (Ursus americanus) using Global Positioning System (GPS) satellite telemetry collars in southeastern Arkansas to assess habitat use and behaviors. Companies test the accuracy of their devices, but researchers have found that natural environments, such as the forested habitat of black bears, can cause an increase in spatial error rates. We therefore tested 1 GPS collar in realistic conditions to help refine data interpretation. We placed the collar at 20 random locations in Columbia County, AR, stratifying habitat type based on data collected from black bears. We determined the …

DLSU Senior High School Research Congress

This research investigated the multifaceted experiences of teenage mothers within BLISTT (Baguio, La Trinidad, Itogon, Sablan, Tuba, Tublay), where adolescent pregnancy remains a persistent social and public health concern. The study highlighted how these young mothers navigated interrupted education, limited economic opportunities, and fragile family relationships, all compounded by cultural stigmas and a lack of reproductive health education. The core research questions explored the lived experiences of these teenagers, the influence of cultural beliefs on societal attitudes, and the challenges and support systems that shaped their lives and futures. Findings revealed that teen mothers within BLISTT faced profound emotional, social, …

A Scoping Review Of Sycophancy In Large Language Models: Operational And Theoretical Recognition, Kallen Zhou, Manning Littlejohn, Isabella Garrard

Endeavors: Mississippi State Undergraduate Research Journal

As large language models (LLMs) usage grows across different domains, sycophancy, the tendency for output to align with users, is increasingly being recognized as a primary issue arising from applying LLMs into critical areas. Current research has provided a variety of theoretical definitions, mitigation techniques, and quantification for sycophancy. However, there is little to no consistency across different papers. This scoping review seeks to connect different works on LLM sycophancy by identifying themes in theoretical definitions, measurement methods, and inducement techniques of sycophancy. By analyzing 26 papers (preprints, conference proceedings, and journal articles) from arXiv, ACL Anthology, and Scopus, this …

Distribution And Impact Of Cogongrass (Imperata Cylindrica) In Northern Mississippi, Carl R. Pulver V, Ryan E. Burke, Elizabeth Esser, Evan Moore, Ashley Schulz

Endeavors: Mississippi State Undergraduate Research Journal

Cogongrass (Imperata cylindrica) is a non-native, rhizomatous grass that has invaded the southeastern United States. It forms dense mats that outcompete native plants, alters decomposition and microbial assemblages, and has highly flammable litter that alters fire behavior, affecting native plant communities. Though surveys for cogongrass have been conducted in southern Mississippi, the degree of cogongrass infestations in northern Mississippi has remained unclear and concerning. This study aimed to update cogongrass location data for the state and identify problem areas to guide state invasive plant management efforts. To provide a starting point, previously documented cogongrass locations were synthesized from natural history …

Near-Infrared Spectroscopy For Monitoring Bovine Respiratory Syncytial Virus Infection In Experimentally Challenged Calves, Erin Blanchard, Jelena Muncan, Grace Beddingfield, Cassandra Barber, Florencia Meyer, Santiago Cornejo, Merrilee Thoresen, Amelia Woolums, Carrie Vance

Endeavors: Mississippi State Undergraduate Research Journal

Bovine respiratory disease (BRD) is a multifactorial disease complex that causes significant economic loss in the cattle industry. Bovine respiratory syncytial virus (BRSV), one of the primary viruses included in BRD, primarily targets the lower respiratory tract and causes a wide variety of subclinical and clinical signs. Current diagnosis techniques require off-site laboratory testing, creating delays that allow BRSV to spread through herds and highlighting the need for rapid diagnostic methods. The objective of the study was to evaluate near-infrared spectroscopy as a diagnostic tool for BRSV detection across varying infection severities. Twenty-two Holstein bull calves were reared in research …

The Thai Journal of Veterinary Medicine

Enterocytozoon bieneusi is now recognised as an emerging pathogen, which can cause a series of intestinal diseases in humans and animals. However, limited information is available about the occurrence of E. bieneusi in hedgehogs. In this study, a total of 205 fecal samples of captive wild hedgehogs (Erinaceus amurensis) were collected from two wildlife conservation centers in Henan and Anhui provinces, China. Genomic DNA was extracted from the stool samples and screened by nested PCR targeting the internal transcribed spacer (ITS) sequences. The overall prevalence of E. bieneusi in captive wild hedgehogs was 44.4% (91/205). Five zoonotic genotypes were identified, …

Biofilm Formation By Histophilus Somni On 3d Bovine Respiratory Tissue Cultures, Bindu Subhadra, Neeti Gandhi, Dianjun Cao, Yue-Jia Lee, Padmavathy Rajagopalan, Thomas J. Inzana

Faculty Publications - Biological Sciences

The development of bacterial biofilms following infection involves bacterial attachment to tissues and maturation of the biofilm matrix (BM). However, studying the development of bacterial biofilms in vivo is difficult to follow. An established example of biofilm formation during host infection is bovine respiratory disease (BRD) due to Histophilus somni. To more accurately investigate in vivo biofilm development, three-dimensional bovine airway organoids comprised of bovine turbinate epithelial (BE) and pulmonary artery endothelial (BAE) cells embedded in type I collagen were developed. Cell-free concentrated culture supernatant (CCS) from biofilm-grown H. somni suppressed proliferation of epithelial cells more than endothelial cells, affected …
