Determining the Relationship Between Phosphorus and Blue-Green Algae Phycocyanin in Western Lake Erie Algal Blooms
No full textAlgal blooms have shown to be detrimental in the Western Lake Erie area in recent years. These algal blooms have proven to be extremely harmful to both public and environmental health, and a definitive cause of these blooms has yet to be found. Determining the parameters of the water in Western Lake Erie is key to finding the reason behind these harmful algal blooms. Harmful algal blooms are not only unsightly, but cause many issues for the people and wildlife in the area, including causing hypoxia and ultimately decimating the fish populations. Data from NOAA’s live-time buoy monitoring systems was collected from late August 2020 through 2024. The data collected included the phosphorus and blue-green phycocyanin levels as the primary focus for this study, but levels for pH, turbidity, and water temperature were also taken. No significant relationship was found between phycocyanin and phosphorus, as the levels were then analyzed using linear regression and showed phycocyanin and phosphorus as being statistically insignificant, with a p-value of 0.58. However, the relationships between phycocyanin and the respective pH, turbidity, and water temperature all proved to be statistically significant with p-values \u3c 0.05. Multiple regression analysis also revealed a significant relationship between phycocyanin and pH with turbidity, with an R2 value of 0.87 and a p-value \u3c 0.05. Research such as this could be the key to eliminating harmful algal blooms in this area, leading to a healthier public and ecosystem in Western Lake Erie
Understanding temporal changes in plant leaf traits of native and non-native Kentucky plants using long-term herbarium records
No full textHerbarium specimens are the most valuable, verifiable, and sustainable records to study the impacts of climate change on the biota. Temporal herbarium data can provide critical information on how species respond to changes in habitat conditions by tracking changes in species’ morphological and phenological traits. This study aims to use Japanese Honeysuckle (Lonicera Japonica) and Common Greenbrier (Simlax rotundifolia) to assess the impact of climate change on invasive and native plants. Further study of these changes can provide vital understanding of how the environment is adapting to major climate change and can even possibly help us know where to focus our efforts to work against global warming
Systematic Leaf Morphology Based on Anatomical Attributes of Members of the Arum Family (Araceae)
No full textThe recent literature concerning the Arum family (Araceae) has grown in number over the past few years, correlating with a rise of their popularity as ornamental houseplants (Haigh et al, 2023). However, I find that literature concerning the anatomical development and morphology of leaves across the family in a comparative study is lacking (Keating, 2002). Currently, within my own personal collection and the shared teaching collection at Murray State University, I have the opportunity to sample a significant representation of species across the family. Through harvesting, sectioning, mounting on a slide, and observation of leaf anatomical structure via a compound microscope, this study aims to provide a comparative anatomy of leaf structure across intrafamilial clades. In doing so, this study also aims to provide an insight into the differences in leaf structure across genera and to highlight the diversity therewithin. Following Yeung’s protocol (1998), I amassed 48 unique specimens and sectioned fresh material using a hand microtome. The key areas of study for this project are the leaf midrib and petiole, as well as including longitudinal sections of the leaf tip to describe hydathodes. The sections are then stained using 1% TBO suspended in a pH=4.4 benzoate buffer and mounted on slides for observation under light microscopy. Microscope images are then to be photographed of key structures throughout the sample, including vascular bundles, chlorenchyma, aerenchyma/mucilage ducts, epidermis, and calcium oxalate crystals. In the present progress of this study, I have noticed differences in the structure and number of vascular bundles, mucilage cells, calcium oxalate crystals, and other overall anatomical features of different species. I plan to examine these differences further and present how structures have changed from more basal to more recent species evolutionarily
Do Higher Association with Intramural Sports result in Better Academic Achievement and longer Retention
No full textCollege varsity sports are a well-known contributor to why students enroll in a university. Varsity sports give the student-athletes a connection where they feel a sense of belonging and the opportunity to represent their university. However, students who are not directly involved in college sports can develop a sense of belonging through being a fan of their university sports teams. There are many benefits of being a fan, including being socially integrated into their university\u27s sports. A study was done by examining students with a team identification scale and persistence in the university. They found that highly identified students were particularly likely to persist in obtaining their degree from the target institution (Wann 2002). Attending games and engaging with other fans gives them a way to integrate themselves into their college to create a sense of belonging.
The current study aims to explore the relationship between participation in college intramurals and student retention at a university. Intramural sports allow students to engage in athletic sports for their enjoyment, without the pressure and responsibilities of being a varsity athlete. Being an athlete or a fan of your university’s sports team gives reasons why students continue to have retention. Students who are involved in intramural sports should have the same levels of retention. Intramural sports athletes allow students to feel a sense of involvement and create a stronger connection to their university. The prediction is that students involved in intramural sports will have higher academic achievement and retention. However, results from the study did not fully support my hypothesis, the data revealed that there are additional factors contributing to the importance of intramural sports. Research indicated that the more students who were involved, and involved in multiple intramural sports, made it more likely them to come back the next school year, as well as making it valuable
Childhood Experiences, Resilience, and Ghanaian Adult Psychological Well-Being
No full textSignificant amounts of research exist concerning adverse childhood experiences and trauma (ACES) and its negative consequences on adult well-being. However, there is minimal research on a concept known as positive childhood experiences (PCES), which are circumstances in childhood that provide safety, security, and predictability in the home. It has been shown that PCES and ACES have co-occurred in childhood. It is apparent that PCES positively affect one\u27s life, can counteract the negative effects of ACE exposure, and can promote resiliency. These studies have been done with samples across the Western Hemisphere. However, this study seeks to examine the effects of adverse and positive childhood experiences on psychological well-being as well as the role of resilience in explaining these relationships among a Ghanaian sample of adults. It is hypothesized that resilience would mediate the relationships between adverse childhood experiences, positive childhood experiences and adult psychological well-being. Data was collected in 2023 from Ghanaian adults (n=303; Mage=21; Age Range=18-50). Findings from this study will better inform our understanding of PCES, their co-occurrence with ACES, and their impact on adult well-being. Findings will also provide strategies for informed care in the Ghanaian population

Pixels from pain: The connection between social media use and childhood trauma in romantic relationships
No full textAttending college provides opportunities for adult functioning and more socialization (Khrapatina and Berman, 2016). Moreover, college allows individuals who have experienced adverse childhood experiences (ACEs) a means of escaping potentially traumatic environments (Khrapatirna and Berman, 2016; Criddle et al. 2022). Most college students also use social media, another means of escapism, and many are at high risk for social media addictions or problematic levels of use (Abbasi, 2018). Current studies show that both childhood trauma and problematic social media use have negative implications for interpersonal relationships (Merz & Jak, 2013; Abbasi, 2018). However, it is unclear whether these two constructs may be related in some way that ultimately negatively influences romantic relationships.
The purpose of this study was to identify the possible relationships between relationship satisfaction and commitment with adverse childhood experiences and screen time on social media. Participants are still being collected in an online form, but roughly eighty-nine participants have been collected so far.
It is possible that college students may be less satisfied and/or committed in their current relationships if they are actively looking for means of escaping childhood trauma environments, especially when that escape is through high screen time use, especially on social media. This may suggest that problematic phone use is a coping mechanism with large relational consequences. Furthermore, these results could shine light on relational consequences that may result from experienced childhood trauma. Thus, the current study explores the relationships between childhood trauma, problematic social media use, and interpersonal factors, such as satisfaction and commitment
