Dorsal Fin Innervation Of The Bluegill, Lepomis Macrochirus, Amanda Torick
Honors Projects
Recent work has shown that the dorsal fins in fish operate not only as locomotive appendages, but also as sensory structures that aid in proprioception. To investigate how fish use these structures for sensing, the innervation of the dorsal fins in bluegill sunfish (Lepomis macrochirus) was assessed through immunohistochemistry assays. I conducted staining using anti-acetylated tubulin (AAT), a non-specific neuron marker, calcitonin-gene related peptide (CGRP) which stains sensory neurons and cytokeratin 20 (CK20), which binds to mechanoreceptor structures. Stained samples of bluegill dorsal fins were imaged under a laser scanning epifluorescence microscope to visualize mechanoreceptors, as well as sensory and …

The human immunodeficiency virus type 1 reverse transcriptase (HIV-1 RT) plays a significant role in viral replication and is one of the targets for anti-HIV. However, a mutation in viral strains rapidly developed the resistance of the com-pounds to the protein, reducing the effectiveness of the inhibitors. This work seeks to utilize machine learning-based quantitative structure-activity relationship (QSAR) analysis in combination with molecular docking simulations to forecast the presence of active compounds derived from medicinal plants. Specifically, the objective is to identify com-pounds that have the potential to operate as inhibitors of HIV-1 reverse transcriptase (RT), encompassing both wild-type and …

Northern Pakistan is interpreted here as including three administrative regions: Khyber Pakhtunkhwa, Gilgit-Baltistan, and Azad Jammu and Kashmir. It is dominated by multiple mountain ranges whose valleys drain, directly or indirectly, into the Indus River. Hazara University, which is in Khyber Pakhtunkhwa, was started in 2002 and its herbarium (HUP) in 2005. Digitization of the herbarium's vascular plants began in 2021 with its records being shared in OpenHerbarium and GBIF. Its online presence is now growing more rapidly than any other Pakistani herbarium. This paper summarizes the taxonomic diversity and geographic origin of its monocot holdings in 2023. In 2023, …

Evidence That Aquaporin 11 (Aqp11) In The Spiny Dogfish (Squalus Acanthias) May Represent A Pseudogene, Christopher P. Cutler, Meghan Canicatti, Esosa Omoregie
Department of Biology Faculty Publications
Various attempts to amplify an AQP11 cDNA from tissues of the spiny dogfish (Squalus acanthias) were made. Two pairs of deoxy-inosine-containing degenerate primers were designed based on conserved amino acid sequences from an AQP11 alignment. These primers yielded some faint bands from gill cDNA that were sequenced. Blast searches with the sequences showed they were not AQP11. An elasmobranch AQP11 nucleotide sequence alignment was produced to identify conserved regions to make further degenerate primers. One primer pair produced a short 148 bp fragment showing particularly strong amplification in gill and intestine. It was sequenced and represented a piece of the …

Genetic selection has been identified as a promising approach for reducing enteric methane (CH4) emissions; a prerequisite for genetic evaluations; however, these are estimates of the necessary genetic parameters based on a population representative of where the genetic evaluations will be used. The objective of this study was, therefore, to derive genetic parameters for a series of definitions of CH4, carbon dioxide (CO2), and dry matter intake (DMI) as well as genetic correlations between CH4, CO2, and DMI in a bid to address the paucity of studies involving methane emissions …

Pennycress (Thlaspi arvense L.) is an annual cover crop known for its exceptional cold tolerance and high oil and protein yields. Pennycress can be integrated into a corn–soybean rotation in the U.S. However, the utilization of pennycress biomass remains largely unexplored, including assessing compositional changes through its growth and organic matter digestibility. This study harvested pennycress at three growth stages, characterized the biomass for anaerobic digestion (AD), and tested the effects of concurrent alkali pretreatment and ensiling on the biomass methane yield. Results showed that the biomass harvested when the plants were undergoing senescence (“third-harvest”) had higher contents of …

Effects Of Hemiparasites In Grassland Restorations Are Not Universal, Anna Scheidel, Victoria Borowicz
Faculty Publications – Biological Sciences
Root hemiparasites infiltrate the vascular tissue of host roots to acquire water and nutrients, which often reduces host growth. Hemiparasites are postulated to be keystone species in grassland communities if they suppress dominant species and increase plant community biodiversity, and ecosystem engineers if they increase nutrient accessibility for surrounding species. We examined keystone effects by evaluating species richness and evenness in 1 m2 plots in a recent prairie restoration where Castilleja sessiliflora was naturally present or absent, and in a longer-established prairie restoration with or without Pedicularis canadensis. We examined ecosystem engineer effects by determining nitrate and phosphate concentrations …

The mechanism of mortality plays a large role in how microorganisms in the open ocean contribute to global energy and nutrient cycling. Salps are ubiquitous pelagic tunicates that are a well-known mortality source for large phototrophic microorganisms in coastal and high-latitude systems, but their impact on the immense populations of smaller prokaryotes in the tropical and subtropical open ocean gyres is not well quantified. We used robustly quantitative techniques to measure salp clearance and enrichment of specific microbial functional groups in the North Pacific Subtropical Gyre, one of the largest ecosystems on Earth. We discovered that salps are a previously …

Guyana manages an estimated 5.3 million hectares of old-growth tropical forests, 29% of its total forest area, for timber extraction. Individuals and companies can apply for time-limited leases that allocate access, management, and extraction rights for timber through a concession system. In many tropical regions, including Guyana, a lack of integrated land use planning often leads to overlapping extractive and forest use rights for logging and mining. Overlapping land rights in turn create uncertainty and limit investments toward sustainable forest management, affecting deforestation and forest degradation rates. In this study, we use matched fixed-effect and difference-in-differences panel data models to …

The essential role of nicotinamide adenine dinucleotide+ (NAD+) in redox reactions during oxidative respiration is well known, yet the coenzyme and regulator functions of NAD+ in diverse and important processes are still being discovered. Maintaining NAD+ levels through diet is essential for health. In fact, the United States requires supplementation of the NAD+ precursor niacin into the food chain for these reasons. A large body of research also indicates that elevating NAD+ levels is beneficial for numerous conditions, including cancer, cardiovascular health, inflammatory response, and longevity. Consequently, strategies have been created to elevate …

The overexpression of HER2 accounts for 20-30% of breast cancer tumors and not only serves as a marker for poor predictive clinical outcomes but also as a target for treatment. Antibody-drug conjugates (ADCs) combine the selectivity of monoclonal antibodies (mAbs) with the efficacy of chemotherapeutic drugs to provide targeted treatment without toxicity to normal tissue. Most of the ADCs currently in the clinic for cancer chemotherapy are based on complex organic molecules. In contrast, the conjugation of metallodrugs to mAbs has been overlooked when there is enormous potential in this area with the resurgence of metal-based drugs as prospective cancer …

Methamphetamine (METH) abuse remains a global health concern, with emerging evidence highlighting its genotoxic potential. In the central nervous system METH enters dopaminergic cells primarily through the dopamine transporter (DAT), which controls the dynamics of dopamine (DA) neurotransmission by driving the reuptake of extracellular DA into the presynaptic neuronal cell. Additional effects of METH on the storage of DA in synaptic vesicles lead to the dysregulated cytosolic accumulation of DA. Previous studies have shown that after METH disrupts intracellular vesicular stores of DA, the excess DA in the cytosol is rapidly oxidized. This generates an abundance of reactive oxygen species …

The Effect Of Urbanization And Temperature On Thermal Tolerance, Foraging Performance, And Competition In Cavity-Dwelling Ants, Brooke A. Harris, Dale Stevens, Kaitlyn A. Mathis
Biology
Human disturbance including rapid urbanization and increased temperatures can have profound effects on the ecology of local populations. Eusocial insects, such as ants, have adapted to stressors of increasing temperature and urbanization; however, these evolutionary responses are not consistent among populations across geographic space. Here we asked how urbanization and incubation temperature influence critical thermal maximum (CTmax) and various ecologically relevant behaviors in three ant species in urban and rural locations in Worcester, MA, USA. We did this by incubating colonies of three species of cavity dwelling ant (Aphaenogaster picea, Tapinoma sessile, and Temnothorax longispinosus) from 2 habitat …

Biology
Fungi have the capacity to assimilate a diverse range of both inorganic and organic sulfur compounds. It has been recognized that all sulfur sources taken up by fungi are in soluble forms. In this study, we present evidence that fungi can utilize gaseous carbonyl sulfide(COS) for the assimilation of a sulfur compound. We found that the filamentousfungus Trichoderma harzianum strain THIF08, which has constitutively high COS-degrading activity, was able to grow with COS as the sole sulfur source. Cultivation with 34S-labeled COS revealed that sulfur atom from COS was incorporated into intracellular metabolites such as glutathione and ergothioneine. COS degradation …

Studying The Genes And Conditions That Influence Root Development, Tessa Holtkamp, Hannah Ordonez Webb
Undergraduate Research Symposium
Root development in plants is essential for their survival and understanding how hormones influence their development can explain how plants grow under different circumstances. Researching how Indole-3-butyric acid (IBA), a hormone that induces root production, affects the plant model Arabidopsis thaliana helps explain the hormone's effect in agricultural crop systems. To understand root pathways, we performed assays on mutant lines of Arabidopsis by growing plants on varying concentrations of IBA. For wild-type and mutant lines, phenotyping experiments like branching of roots, lengths of stems, and root length were conducted along with PCR and restriction digest genotyping experiments to compare their …

Effects Of Beauveria Bassiana On The Mortality And Thorax Width Of Bombus Impatiens Colonies, Bri Petty
Undergraduate Research Symposium
Pesticides are widely used to protect against unwanted insects, but risk assessments of the effects on pollinators have traditionally only been applied on an individual level, not a population level. This has allowed many pesticides to be approved without the knowledge of sub-lethal effects, such as life history characteristics and population structure to name a few. The biopesticide BotaniGard, containing the entomopathogenic fungus Beauveria bassiana, has previously been thought to be safe for non-targeted insects, but recent studies have found it to have significant negative effects on pollinators. Such negative effects can include decrease in longevity and odorant responsiveness with …

Investigations into aDNA offer a window into the past that modern DNA and paleontological studies alone cannot provide and help address the evolution and connections between hominids, domestication timelines, the analysis of populations over time, and general diversity. Progress in aDNA research has been inherently technology-driven, with modern molecular biology methods, such as the inventions of Polymerase Chain Reaction (PCR) and Next Generation Sequencing (NGS), substantially increasing the analysis possibilities of aDNA. My research this semester has taken me along two parallel paths of investigation: literary research into aDNA and practical exposure to the laboratory techniques used in its analysis. …
