Insect Apocalypse? Population Patterns Of Aquatic Macroinvertebrates Across North America, Analiese Kate Bauder
Insect Apocalypse? Population Patterns Of Aquatic Macroinvertebrates Across North America, Analiese Kate Bauder
Honors Thesis
There is a common idea that there is an “insect apocalypse”, that insect populations are on a drastic decline. To test this hypothesis we took data collected by the National Ecological Observatory Network (NEON) from 2015 to 2023 and analyzed it to create a time series model depicting the population of aquatic macroinvertebrates at 34 sites across North America (Appendix 1). NEON is an NSF funded, continental-scale observation facility designed to collect long-term open-access ecological data to better understand the complexities of Earth's ecosystems and how they are changing. From this model, we defined the slope of the change in …

Karbala International Journal of Modern Science
In our study, for the first time worldwide, to the best of our knowledge, cobalt oxide nanoparticles (CoO NPs) were synthesized using naringin (Nar) extracted from citrus peels. The properties of the prepared Nar-CoO NPs were studied using field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), ultraviolet-visible (UV-Vis), X-ray diffraction (XRD), and Fourier transform infrared (FTIR) spectroscopy. All the test results demonstrated the efficiency and success of the nanofabrication process. The solution was then exposed to three types of diode lasers: red (650 nm), green (532 nm), and blue (405 nm). The purpose of this study was …

Biology
To the Editor: Pulmonary veno-occlusive disease (PVOD) is a rare, severe group 1 pulmonary arterial hypertension (PAH) subtype with poor survival (1). PAH-targeted vasodilators can cause life-threatening pulmonary edema in PVOD, underscoring the need for diagnostic tools to distinguish it from other PAH subtypes (1). In patients and mitomycin C–induced (MMC-induced) model animals, aberrant activation of integrated stress response (ISR) via protein kinase R (PKR) drives cardiovascular phenotypes of PVOD (2–4). Inhibition of the PKR-ISR axis, using either the PKR inhibitor C16 or the ISR inhibitor ISRIB, reverses PVOD phenotypes (2–4). Because GDF15 is a cytokine induced by the ISR …

Effects Of Photo-Oxidized Crude Oil On Gulf Killifish Early Life Stages, Charles Campbell
Effects Of Photo-Oxidized Crude Oil On Gulf Killifish Early Life Stages, Charles Campbell
LSU Master's Theses
Photo-oxidation of spilled crude oil generates polar compounds that can heighten toxicity to marine fish embryos. We investigated the effects of photo-oxidized crude oil on early life stages of Gulf killifish (Fundulus grandis) by exposing embryos under flow-through conditions to water-accommodated fractions of four oil treatments: fresh oil unexposed to either sunlight or weathering referred to as dark control (DC), a UV-light oxidized whole oil (LT), the polar fraction extracted from LT (Pol) and the remnants after extracting the Pol from LT (NP). Oil loadings of 0.38–3.00 g oil/kg water were tested. Total PAH concentrations and chemical profiles …

Population Structure Analysis Of Four Basal Higher-Attines Using Bioinformatic Approaches, Gabriel Mcdanield
Population Structure Analysis Of Four Basal Higher-Attines Using Bioinformatic Approaches, Gabriel Mcdanield
Biology Theses
Metapopulations within the family Formicidae are unique among other animals due to the large colonies they build, and the mating strategies required to fertilize a specialized reproductive caste that will often produce young for the life of the colony. One group of ants, the fungus-gardeners (tribe Attini). The population structure of North American non-leafcutting, fungus-gardening ants has been understudied, especially in the southwest of the United States. Additionally, not much is known about their dispersal biology, so the dynamics of dispersal of these species and how they affect population structure is likewise not well known. To shed light on the …

Augmented Reality-Assisted E-Module On Temperature Andheat Content (Emarks), Tetri Sabrina, Ika Mustika Sari, Dedi Sasmita
Jurnal Pendidikan Sains
Temperature and heat content (calor) material in physics often involves concepts and phenomena that are difficult to observe directly or are abstract (such as energy transfer, particle movement, and changes in state). EMARKS (AR-based E-modules) are important because Augmented Reality (AR) allows the visualization of these abstract concepts in the form of interactive 3D models in the user's real environment. This helps students understand the concepts more concretely and easily. The development of E-modules is an innovation in learning media that is relevant to the demands of the digital era and the needs of modern students. The use of advanced …

ABSTRACT OF THE DISSERTATION Mechanisms of Antibody-Mediated Protection in Severe Acute Respiratory Syndrome Coronavirus 2 Infection by Samantha Rae Mackin Doctor of Philosophy in Biology and Biomedical Sciences Immunology Washington University in St. Louis, 2025 Professor Michael S. Diamond, Chair Coronaviruses (CoVs) are enveloped, non-segmented, positive-sense RNA viruses belonging to the Coronaviridae family. The subfamily Coronavirinae includes four genera: alpha-, beta-, gamma-, and deltacoronaviruses. While gamma- and deltacoronaviruses primarily circulate in wild or domestic birds and have shown the potential for cross-species transmission, alpha- and betacoronaviruses mainly infect mammals, resulting in respiratory illnesses that can be mild or severe.

Improving Coral Restoration Outcomes Through Novel Molecular Applications, Matthew H. Gamache
Improving Coral Restoration Outcomes Through Novel Molecular Applications, Matthew H. Gamache
USF Tampa Graduate Theses and Dissertations
Coral reef ecosystems are declining globally from numerous stressors, including localized pollution, disease, and marine heatwaves induced by climate change. To preserve these ecosystems, it is critical to identify corals that can withstand stressors—primarily future marine heatwaves—and prioritize them for coral restoration efforts until these stressors are mitigated. Coral responses to thermal stress can be influenced by several partners, including mutualistic microalgae and a vast prokaryotic community. Here, I use advanced molecular techniques to examine which partners (coral host, algal symbiont, and microbial communities) are associated with coral health, how they contribute to holobiont physiology, and their potential to increase …
