Following the description of Cambarus callainus (Thoma et al., 2014), a range-wide survey was completed to determine the current distribution and conservation status of the species, resulting in federal protection enforced by the United States Fish and Wildlife Service in 2016 and listing as Threatened on the U.S. Endangered Species Act. While significant efforts evaluating the life history of Cambarus callainus have been completed (Vopal & Loughman, 2021), a more specific analysis of microhabitat utilization, habitat preference, resource partitioning, and movement patterns remains incomplete. High-resolution data involving the specific habitat requirements of crayfishes are lacking, which is recognized as a significant limiting factor in crayfish conservation and management (Jones & Bergey, 2007). We aim to resolve these unknowns by observing potential micro- and macrohabitat associations and individual movement patterns of adult C. callainus individuals, assessed via radiotelemetry across a temporal scale. We also hope to determine movement biology and any potential accidental or behavioral drift of crayfish young-of-the-year. Previous studies indicate that radiotelemetry methods are effective in determining the movement biology of Cambarid crayfishes (Bubb et al., 2004, 2006a, 2006b; Sadecky, 2020). Radio-monitoring of C. callainus will be beneficial for conservation management involving this species and will expand our ability to efficiently address issues affecting Threatened and Endangered crayfishes in the future.
根据对Cambarus callainus的描述(Thoma et al.， 2014)，完成了一项范围广泛的调查，以确定该物种的当前分布和保护状况，从而在2016年由美国鱼类和野生动物管理局实施联邦保护，并将其列为美国濒危物种法案的受威胁物种。虽然已经完成了对callainus生活史的评估(Vopal & Loughman, 2021)，但对微栖息地利用、栖息地偏好、资源分配和运动模式的更具体分析仍然不完整。缺乏涉及小龙虾特定栖息地需求的高分辨率数据，这被认为是小龙虾保护和管理的重要限制因素(Jones & Bergey, 2007)。我们的目标是通过观察潜在的微观和宏观栖息地关联以及成年callainus个体的个体运动模式来解决这些未知问题，并通过无线电遥测技术在时间尺度上进行评估。我们还希望确定运动生物学和任何潜在的意外或行为漂移小龙虾的年轻。以往的研究表明，无线电遥测方法可以有效地确定康巴底小龙虾的运动生物学(Bubb et al.， 2004,2006a, 2006b;Sadecky, 2020)。对callainus的无线电监测将有助于该物种的保护管理，并将扩大我们未来有效解决影响受威胁和濒危小龙虾问题的能力。

Escherichia coli (E. coli) is a gut bacterium found in intestinal tracts of warm-blooded animals and pollutes water bodies through fecal contamination. At high concentrations some strains can cause serious illnesses if ingested by individuals. High concentrations of E. coli can also indicate the presence of other potentially harmful pathogens. Surface waters can become contaminated via nonpoint sources of runoff from agricultural lands and resident waterfowl population and point sources including leaking sewage infrastructure and combined sewer overflows (CSOs). In freshwaters E. coli can live free floating throughout the water column or attached to streambed sediments, and when these sediments are resuspended due to precipitation E. coli concentrations increase in the water column. The USEPA has set a maximum safe limit for recreational waters at 235 CFU/100 mL of water for a single sample and a 30-day five-sample mean of 126 CFU/100 mL. We chose seventeen sampling sites to monitor and identify trends and predictors of E. coli in Wheeling Creek watershed, in the northern panhandle of West Virginia. We measured water temperature, pH, dissolved oxygen, conductivity, chloride, and turbidity in the field and used an IDEXX system for E. coli quantification. Our results indicate that 51% of samples (125 out of 245) have exceeded that single sample safe limit (235 CFU/100ml). Escherichia coli concentrations are increasing with increasing urban development and show a positive correlation with turbidity, this could suggest that humans are the primary source of E. coli in Wheeling Creek.

In herpetoculture, there is debate as to whether ultraviolet-B, UVB, lighting is required for providing adequate welfare for snakes in human care. Many believe this supplemental lighting is unnecessary and is not utilized by the snakes, stating that snakes survive and breed in its absence. Previous studies using pythons and corn snakes have demonstrated that offering UVB lighting appears to have a significant effect on their physiology. These studies focused on the increase of 25-hydroxyvitamin D3 concentrations in the blood after UVB exposure. In the present study, false water cobras, Hydrodynastes gigas, were chosen because they are active, diurnal snakes and are therefore more likely to seek out UVB in the wild in comparison with other fossorial snakes. The level of UVB that will be provided is based on the tropical climate of the range for H. gigas. Twelve hatchling H. gigas will be divided into two groups with Arcadia T5 14% UVB lights provided for one group and LED lights provided for the other. The behavior of the snakes will be monitored through video recording to determine the effects of UVB lighting on basking behavior and total time exposed to the UVB lighting. To identify physiological effects, radiographs will be taken to determine any change in bone density. This study aims to find if offering UVB lighting promotes basking behavior and affects bone density in H. gigas. The results of this study can be used to further increase welfare standards for snakes in captivity.

Surface coal mining has been a major economic force in the Appalachian region for hundreds of years. Surface coal mining leads to runoff known as acid mine drainage (AMD) which infiltrates and severely degrades freshwater streams. Acid mine drainage impacted streams often see a marked decrease in biodiversity especially Ephemeroptera, Plecoptera, and Trichoptera (EPT taxa) which are intolerant to pollution. We researched the water quality in four streams. Two downstream mines were impacted by AMD while the other two served as control or unimpaired sites. Water chemistry of all four streams was measured including sulfate, iron, and magnesium using a YSI 9500 photometer. The pH of each stream was measured using a YSI Quatro meter. We found elevated levels of sulfate and iron in the impaired streams while magnesium levels varied across sites. The pH tended to be lower in the impaired streams but remained fairly alkaline ( pH > 5). These data are useful for understanding the chemistry of impaired streams and how freshwater macroinvertebrates may respond to these chemical parameters. Additionally these data aid in remediation efforts which may be dependent on specific water chemistry.

Francisella tularensis is an intracellular pathogen and the causative agent of tularemia. The F. tularensis type six secretion system (T6SS) is required for phagolysosomal escape and invasion of erythrocytes. An effector of the T6SS, PdpC, is required for phagosomal escape and we wanted to test if PdpC was also required for erythrocyte invasion. We constructed a pdpC-null mutant in the live vaccine strain, F. tularensis LVS. The pdpC-null strain is required for invasion of both human and sheep erythrocytes and reintroduction of a copy of pdpC, in trans, rescues this phenotype. Differential Immuno-Fluorescence Microscopy (DIFM) showed that the pdpC-null strain is affected in attachment as well as invasion. Further, a fluorescently labelled pdpC-null strain of F. tularensis LVS was unable to proliferate in THP-1 human peripheral blood monocyte cells. Finally, we constructed a fluorescent fusion of pdpC to emgfp and the resulting PdpC-EmGFP fusion protein localizes as discrete foci in a subset of broth cultured F. tularensis LVS cells. Our results confirm previous observations that PdpC is required for infection and virulence in phagocytic host cells and are the first description of an effector of the Type Six Secretion System that is required for erythrocyte invasion. The pdpC-emgfp strain will be a useful tool to further characterize the role of PdpC in both macrophage infection and red blood cell invasion.

Facial recognition using artificial neural networks is a biometric technology currently being used in fields such as cybersecurity and criminal investigation. We sought to automatically distinguish between an image of a happy human face and an image of a sad human face with predictions that are better than random guesses. We trained a machine learning model (VGG16, a type of convolutional neural network) on a public image dataset of 12,000 human faces. The resulting model predicted the emotion label 93% of time when shown a test set of 200 images that the model had never seen during training. The results show that the VGG16 convolutional neural network learned features from our data that produced an output which was sufficient to train the additional layers of the model to perform our task at 93% accuracy. We suspect this is because VGG16 was already familiar with features that it learned from ImageNet (a separate dataset of over 2 million images). It is currently unknown whether our model can predict labels for new images outside of the FER13 dataset, but preliminary tests show promising results. Our model was trained using a cloud computing service and a relatively small amount of data, indicating that these kinds of results are easily obtainable by all.

The goal of the SUCCESS project is to recruit, retain, and graduate low-income STEM students with high motivation and entrepreneurial mindset that will increase the likelihood of employment in technology-based businesses and/or the creation of technology-based start-up ventures in the region. The program will contribute to society by increasing the number of career-ready STEM graduates from low-income and underrepresented populations and strengthening the pipeline of qualified engineers and scientists, improving the home state, the Appalachian region, and the U.S. economic competitiveness. So far, the project provided scholarships to eight (8) student “scholars” for the cohort in year 1. We are currently in the process of recruiting new students for the second cohort in year 2. Faculty mentors from Electrical and Computer Engineering (ECE) and Computer Science and Information Systems (CSIS) departments are regularly meeting with the scholars to ensure they are making good progress to achieve student success. To facilitate early introduction to research, entrepreneurship, and STEM careers, the scholars were assigned to industrial mentors, encouraged to attend and get involved with campus activities including career fairs, student organizations, senior design seminars, and entrepreneurship courses. SUCCESS team is regularly collecting and analyzing feedback from scholars to ensure that the necessary improvements are implemented. Every semester, scholars’ feedback is collected through pre-, mid- and post- surveys. These surveys provide insights on scholars’ course/program performance, career updates, and also the level of persistence towards their program of study and entrepreneurship minor. This project is funded by NSF DUE S-STEM Program from 2021-2026.

A growing number of human pathogens are becoming resistant to most common antibiotics. Each year, antibiotic-resistant infections are responsible for 35,000 deaths in the United States and billions of dollars in health care costs. This problem is magnified by the fact that very few new antibiotic therapies have been developed and approved for human use in recent years. Historically, plants and other products found in nature have served as essential sources for the discovery of novel antibacterial agents. Piper species are aromatic plants whose secondary metabolites have been shown to have wide ranging human health effects including anti-tumor, anti-diabetic, and anti-inflammatory activity. In collaboration with Dr. Claudia Ospina at Inter American University of Puerto Rico, we generated a crude chemical extract from Piper leaves and will be assessing the antimicrobial activity of this extract against a broad range of bacterial species known to exhibit multidrug resistance. Future studies will involve isolating the active compounds (and/or fractions) from the Piper crude extract using column chromatography and/or HPLC. The pure compounds will be characterized using different spectroscopic techniques such as NMR, IR and MS. We anticipate isolating and identifying several bioactive compounds from the crude Piper leaf extract that exhibit antimicrobial activity.

We anticipate isolating and identifying several bioactive compounds from the crude Piper leaf extract that exhibit antimicrobial activity.","PeriodicalId":92280,"journal":{"name":"Proceedings of the West Virginia Academy of Science","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74231368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gateway math courses can be a major hurdle for students to get over in order to continue on with their majors, especially STEM majors. Previously, students could have taken up to four semesters of remedial math before being able to place into the first gateway math course needed for their major. With Math Support, students no longer have to take those remedial courses; the remediation is built in to the course in addition to the regular level content. These co-requisite courses allow students to start into their major courses much sooner than in the past, therefore allowing them to stay on track in their major and finish successfully. Developmental math courses have been replaced with co-requisite and accelerated learning models. All students can now progress through gateway courses within their first year, regardless of test scores. Gateway courses are offered with additional support to aid students in learning and understanding and fill in any gaps. Fairmont State was one the first colleges in WV to offer these services at full-scale. Attendees will be given an overview of Math Support at Fairmont State and how we have adapted our course to meet the changing needs of students as a result of the COVID pandemic. More data will be reported.

Human skeletal remains are important teaching tools in natural science courses. Many teaching skeletons at universities tend to be forgotten and stored away as they become damaged and are replaced with plastic models. Today, controversy over the ethical acquisition and treatment of skeletal material directly affects many museums and educational institutions. Skeletons tell us a substantial amount of information about each individual and how they lived, giving us an insight into different populations and lifestyles. An unknown number of teaching skeletons were discovered disarticulated, damaged, and stored in a backroom at Fairmont State University. As we do not know the exact means by which these teaching skeletons were acquired these individuals should be analyzed, repaired, and stored properly. For this project, we determined the minimum number of individuals (MNI) and completed standard osteological analyses for each individual. The MNI discovered was 44 while only 16 had enough bones to complete a standard osteological analysis. Standard osteometric and macroscopic analyses were performed on the individuals using Data Collection Procedures for Forensic Skeletal Material 2.0 and the Modified Istanbul Protocol. Age, sex, ancestry, height, metabolic bone disease, and potential cause of death were determined using standard paleopathological techniques. Preliminary results show that all individuals are over 20 years old, 3 individuals between 20-35 years, 3 between 35-50 years, 2 35+ years, and 6 20+ years old. Two individuals were of indeterminate sex, 3 probably male, and 5 probably female. Nine individuals were of Asian ancestry.
