Effects Of Varying Biochar Concentrations On The Growth Of Lactuca Sativa (Newham Bibb Lettuce), Lauren Holler

Williams Honors College, Honors Research Projects

The objective of this research experiment was to investigate the effectiveness of using biochar in potting soil in terms of plant growth and soil quality. This experiment was carried out using varying amounts (0%, 5%, 10%, and 20%) of biochar in the soil to see its effect on seed germination, plant growth, and soil quality such as pH, water retention, and soil temperature. The aim of the experiment was to identify whether biochar can be used in soil to promote healthier and stronger plants. There were four treatments which included 0% (Control), 5% (Treatment 1), 10% (Treatment 2), and 20% …

Bridging The Gap In Science Research: Preparing Students For College- Level Research In The Sciences, Victoria Helwig, Yaoguang Li

UConn Library Presentations

Many first-year students enter college unprepared to fully engage with scientific literature and academic library resources. Drawing on experiences from academic librarians working with STEM students, this session explores common gaps in science research skills, including navigating databases, identifying scholarly sources, and understanding the structure of scientific literature. Participants will be introduced to practical strategies and classroom-ready activities to better prepare students for college-level research. Discussion questions: What science research skills do students struggle with most when entering college? How can high school instruction better support these skills? Where can librarians and educators collaborate to support student success?

Discovering The Genetics Underlying Speciation Traits In Heuchera (Coral Bells), Tajinder Singh

Honors Theses

Hybridization is a key evolutionary mechanism for generating biological diversity, ultimately shaping diversification and adaptation of plant lineages in natural and agroecosystems.  Our understanding of the frequency, distribution, and significance of hybridization is rapidly increasing, but the external driving forces that dictate why certain species hybridize, and others do not remain obscure. The physical traits that shape gene flow and trait sharing among species are likely to be among the key factors that directly control hybridization. Gene flow in most plants is mediated by pollinating insects and thus by pollination syndromes, which are suites of floral traits that have evolved …

How Pollinator Populations Can Impact Chronic Disease Risk, Kylee Cubbison

Honors Projects

This project investigates how pollinator populations can impact chronic disease risk. Pollinator populations are declining, which can have serious implications for human health. Declining pollinator populations can limit healthy food production and affordability. Poor nutrition is a major risk factor for most chronic diseases. Less healthy food available for people to consume can negatively impact diets and increase the risk of developing chronic diseases. This project aims to address a potential gap in research existing on this specific topic regarding pollinator populations and human chronic disease risk. A brochure targeted towards educating the general public on this topic was created …

Contemporary challenges –  such as the full-scale war, which has led to the loss of productive lands in southern and eastern …

New Records Of The American Bumble Bee, Bombus Pensylvanicus, In Michigan, Sharron Z. Miller, Logan M. Rowe, Lillyanna Widdicombe, Robert P. Jean, Rufus Isaacs

The Great Lakes Entomologist

We report recent detections of the American bumble bee, Bombus pensylvanicus (De Geer) (Hymenoptera: Apidae), in 16 counties of Michigan, USA. This bee species is currently listed as state endangered in Michigan. The current report provides an update on the distribution of B. pensylvanicus in Michigan from collections made between 2020 and 2024, including detections from at least 21 locations in the Lower Peninsula, expanding the known distribution in this state. These samples were from four pollinator survey projects with records from photographs and collections and two online participatory science programs where users uploaded photographs of this species while verified …

Ovipositional Behavior Of The Twig Girdler (Cerambycidae: Oncideres Cingulata) On Stems Of Mockernut Hickory (Carya Tomentosa) In Arkansas, R. Tumlison, L. Serviss

Journal of the Arkansas Academy of Science

The Twig Girdler (Cerambycidae: Oncideres cingulata) is a long-horned beetle that girdles stems of certain species of trees to prepare a habitat for its offspring. The stems eventually die, break, and fall from the tree, but the beetle usually had already laid its eggs within the stems. Eggs are laid singly, almost always at growth rings or leaf bases. Because the space for the young to develop is finite, laying too many eggs could cause reproductive failure and too few eggs would be suboptimal. We hypothesized that the female laying eggs should be able to evaluate the stem and …

Neonicotinoid Bioaccumulation In Bluegill And Bullhead Within Lake Julia And Lake Zumwalde, Jake Stuber

Journal of Earth and Life Science

Brown Bullhead Ameiurus nebulosus, Yellow Bullhead Ameiurus natalis, and Bluegill Lepomis macrochirus are unique in their stark differences. Bullhead are scaleless bottom feeders that can tolerate high pollution and low O₂ conditions. In contrast, Bluegill are scaled, aggressive nesters and are less tolerant of high pollutants or low-oxygen conditions. Among these pollutants include a class of chemicals called neonicotinoids (hereafter referred to as neonics). Neonics are a class of insecticides primarily used within agriculture and pest management. Due to the effectiveness, application has escalated on a global scale. They have been well documented by many toxicology assessments. …

A Novel 3d Imaging Approach To Study Evolutionary Innovations In Solanaceae Inflorescences, Devin L. Jackson, Joonseog Kim, Wenheng Zhang Dr.

Undergraduate Research Posters

Understanding the relatedness of angiosperms and the evolution of their inflorescence remains challenging, as these structures are highly modified and prone to convergent evolution. The current research describing inflorescence architecture, whether genetically or morphologically focused, typically relies on text based explanations, 2D images, or 3D based models created with CAD modeling software. This creates a disparity in the reader's understanding of these models since descriptions rely heavily on the author's interpretation of the inflorescence. The goal of our study is to bridge this disconnection by producing anatomically and color-correct 3D inflorescence models using Solanaceae flowers that readers can explore directly, …

Layers Of Biodiversity: Linking Urban Garden Plants And Arthropods, Chenyang Su

Dartmouth College Ph.D Dissertations

Diverse arthropods play essential roles in urban agriculture, while urban agriculture provides food and habitat that support arthropod biodiversity in fragmented urban landscapes. In urban community gardens, a form of urban agriculture characterized by allotment-style gardens, arthropods interact with plants and green space across multiple spatial scales of management, from individual gardeners' plots to broad urban landscapes. Understanding how plant communities in urban community gardens and urban landscapes shape arthropod biodiversity and interactions across scales can inform both agricultural management and urban biodiversity conservation. In this thesis, I conducted a series of field studies on ecologically and economically important arthropods …

Determination Of An Effective Natural Boxelder Bug (Boisea Trivittata) Repellent, Reyna Chavez

Theses and Dissertations

This study investigates the use of ecofriendly repellant alternatives to pest management to control boxelder bugs (Boisea trivittata). This bug gathers by the thousands on warm surfaces of exterior suburban homes during early fall and late spring. I determined bug repellency to turmeric oil (Curcuma longa), catnip (Nepeta cataria), citronella (Cymbopogon nardus), and lavender (Lavandula angustifolia). The treatments consisted of essential oils containing 20% methanol. All treatments demonstrated repellency of Boxelder bugs. Citronella was the most effective and had the highest level of repellency range of 90-99%. Catnip was the least effective with a repellency range of 63-82%.

Examining Private Landowner And Stakeholder Attitudes, Perceptions, And Knowledge Of Prescribed Fire In Louisiana, Chloe E. Crawford

LSU Master's Theses

Periodic fire was a primary driver of ecosystems across the Southeastern United States for millennia; however, fire suppression policies have become pervasive in the United States and led to increased fuel loads in forests as well as reduced biodiversity and reduced disease resilience. Prescribed fire presents a risk mitigation strategy and land management tool whereby practitioners can apply fire to the landscape in a controlled manner, thus reaping the benefits of fire while minimizing the risks associated with fire. Land in Louisiana is primarily privately managed and owned, so state-level conservation goals cannot be met without private landowner participation. As …
