In Situ Carbon Uptake Of Marine Macrophytes Is Highly Variable Among Species, Taxa, And Morphology, Julian Jacobs, Lucian Himes, Florybeth Flores La Valle Dr.

Summer Undergraduate Research in Biology Program

Macroalgae form important coastal ecosystems and are considered to be highly

productive, yet individual macrophyte carbon uptake rates are

poorly documented and methodologies for in situ assessments of productivity

are not well developed. In this study, we employ a 13C enrichment method in

benthic chambers to calculate carbon uptake rates and assess d13C signatures of

a large stock of nearshore benthic macroalgae varying in taxa and morphology in

Southern California. Our objectives are to 1) identify the variability of carbon

uptake and inorganic carbon use among individuals of the same species or

morphology and speculate how macroalgae might respond to …

Vinyl Chloride Accident Unleashes A Toxic Legacy, Chengjun Li, Peng Gao, Riqing Yu, Huan Zhong, Mengjie Wu, Su Shiung Lam, Christian Sonne

Biology Faculty Publications and Presentations

A railroad accident on February 3, 2023, led to the release and combustion of 115,580 gallons, equivalent to over 437,000 L, of vinyl chloride monomer (VCM) in East Palestine, Ohio [1]. This monomer is used in polyvinyl chloride (PVC) production, and its burning produces additional toxins such as hydrochloric acid and lethal phosgene, known as a notorious chemical weapon during World War I

Comparing Pollinator Communities: Onu’S Swanberg Sanctuary V. Midewin National Tallgrass Prairie, Stephanie Clark

Pence-Boyce STEM Student Scholarship

Pollinators play a key role in both ecosystem diversity and agricultural productivity [1]. Declines for pollinators have been seen across the globe and have been linked to agriculture and urbanization [2]. Several species in Illinois have declined so severely, they are now endangered or of significant conservation concern [1]. Past ONU students have collected data on the bees in Northeast IL. However, there is no data for what species are at the Sanctuary. This study will provide baseline data for future studies and by comparing with Midewin, a mature restoration, we can gain an understanding of distinctiveness.

Sex-Specific Effects Of High-Fat And Ketogenic Diet On Inflammatory Responses In The Hippocampus, Shalet James

Honors Theses

Poor diet and metabolic diseases (obesity, Type 2 diabetes) are associated with increased risk of neurodegenerative and neuropsychiatric disorders, including Alzheimer’s disease, anxiety, and depression. Studies indicate that inflammation in the hippocampus could be one mechanism linking these conditions. Previous findings on inflammation, specifically glial activity in response to a high-fat diet, indicate sex differences in microglial responses in the hippocampus. The ketogenic diet is characterized by a high-fat, low-carbohydrate, and moderate-protein diet. While the ketogenic diet is very high in fat content, it may also possess neuroprotective properties against brain aging and neurodegenerative disorders, as well as boost mood …

Carnivore And Ungulate Occurrence In A Fire-Prone Region, Sara J. Moriarty-Graves

Cal Poly Humboldt theses and projects

Increasing fire size and severity in the western United States causes changes to ecosystems, species’ habitat use, and interspecific interactions. Wide-ranging carnivore and ungulate mammalian species and their interactions may be influenced by an increase in fire activity in northern California. Depending on the fire characteristics, ungulates may benefit from burned habitat due to an increase in forage availability, while carnivore species may be differentially impacted, but ultimately driven by bottom-up processes from a shift in prey availability. I used a three-step approach to estimate the single-species occupancy of four large mammal species: mountain lion (Puma concolor), coyote …

Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

The Effects Of Extended Fructose Access On Relative Value And Demand For Fructose, Saccharin, And Ventral Tegmental Stimulation, Megan Halloran

Theses and Dissertations--Psychology

Globally, food addiction (FA) is a growing area of research and is largely attributed to the availability of foods that are both energy dense and high in fats and sugars. Further, it has been suggested, that sugar and fat, when consumed frequently, have properties similar to drugs of abuse. While the validity of FA is questioned, researchers have drawn parallels between substance use disorder (SUD) and FA. For example, sugar binge models emphasize craving, withdrawal and binging as primary components of FA, which are also hallmarks of SUD. Additionally, both natural rewards, like sugars, and drug rewards act on the …

Ecological Risk Assessment Of Transgenic Conditional Lethality Systems For Genetic Biocontrol Strategies, Fernan Rodrigo Perez-Galvez

Theses and Dissertations--Entomology

Genetic strategies of insect pest control are receiving increased interest due to recent advances in genetic engineering. By introducing alleles that make males functionally sterile, genetically modified (GM) insects can be used in area-wide pest management programs similar to the Sterile Insect Technique (SIT). Genetic control strategies carry several potential benefits, including improved efficacy and specificity, lower operation costs, and reduced dependence on chemical insecticides, but their use is still controversial despite extensive technical documentation indicating their innocuity to humans and the environment. This hesitation is likely due to the novel nature of the approach.

Structural Files For The Etr1 Ethylene-Receptor Dimer Based On Computational Modeling, Beenish J. Azhar, Safdar Abbas, Sitwat Aman, Maria V. Yamburenko, Wei Chen, Lena Muller, Buket Uzun, David A. Jewell, Jian Dong, Samina N. Shakeel, Georg Groth, Brad M. Binder, Gevorg Grigoryan, G. Eric Schaller

Dartmouth Scholarship

Structural models for the ETR1 homodimer were generated with AlphaFold-Multimer. Coppers were modeled under two potential coordinations involving Cys65 and His69 of the ETR1 homodimer, one in which the two coppers are bound independently and do not share an interaction with each other, and another where they are closely bonded.

Curriculum Strategy To Increase College Student’S Motivation, Ability And Opportunity Resulting In Reduction In Wasted Food, Sarah D. Brunnig

UNF Graduate Theses and Dissertations

Concerns about Food Loss and Waste (FLW) have been rapidly growing worldwide as it came to be understood how the loss of about one-third of the edible food produced globally leads to environmental damage, leads to loss of about USD 1 trillion and keeps food from hungry people. Consumers in developed countries account for the largest majority of food that is wasted. College presents an excellent opportunity to reach young adults as they are developing their identity, self-efficacy and life skills. Utilizing the Motivation-Ability-Opportunity Framework, this research’s overall goal was to find a Curriculum Strategy to engage allied health students …
