Light, Symbiosis, And The Biology Of Corals, Taylor R. Lindsay Jan 2025

Light, Symbiosis, And The Biology Of Corals, Taylor R. Lindsay

Open Access Dissertations

Light is critical for the survival of most shallow water scleractinian corals. Corals are mixotrophs, acquiring energy via both feeding on water column plankton and photosynthesis via a symbiotic relationship with dinoflagellates living within their tissues. Corals rely heavily on photosynthetically derived metabolites through this symbiotic relationship, intrinsically linking their biology to light availability. Corals are known to modulate their biology to maximize light capture. However, there is a limited understanding of the interaction between morphology, physiology, and energetic strategy, as well as how light may affect these relationships. In Chapter 1, we quantified the morphology, physiology and energetic …

Impacts Of Multiple Coastal Stressors Across Life-History Stages In The Eastern Oyster, Amaelia Zyck Jan 2025

Impacts Of Multiple Coastal Stressors Across Life-History Stages In The Eastern Oyster, Amaelia Zyck

Open Access Dissertations

Urbanized estuaries are characterized as a complex of biotic and abiotic stressors, which currently challenge marine life and are expected to intensify and become increasingly unpredictable under the ongoing impacts of climate change. The persistence of coastal species that inhabit these stressful environments will ultimately depend on their ability to adapt. Many of these species have complex life cycles, featuring distinct morphological and physiological developmental stages that can exhibit unique responses to environmental pressures. However, since all stages share the same genome, selective pressures acting on one stage can have cascading effects throughout the life cycle. The larval stage, being …

Non-Coding Rnas As Regulators Of Coral Biology, Jill Ashey Jan 2025

Non-Coding Rnas As Regulators Of Coral Biology, Jill Ashey

Open Access Dissertations

Coral reef ecosystems face increasing threats from climate change, yet knowledge of the molecular mechanisms that underlie coral acclimatization, resilience, and development remains incomplete. Among these mechanisms, non-coding RNAs (ncRNAs), specifically microRNAs (miRNAs), are emerging as key regulators of gene expression in response to environmental and developmental cues. This dissertation explores the diversity, function, and dynamics of ncRNAs in scleractinian corals across ecological, physiological, and developmental contexts. In Chapter 1, I present the first comprehensive analysis of ncRNAs - specifically long ncRNAs (lncRNAs), miRNAs, and piwi-RNAs (piRNAs) - in three reef-building coral species from Mo’orea, French Polynesia: Acropora pulchra, …

Backyard Chimeric Microbiomes: K-12 Participatory Science, Abigail Saucier

Honors Theses and Capstones

The US education system has seen a recent push for more secondary school curriculum to include STEM (Science, Technology, Engineering, and Mathematics) materials and activities. Middle and high school is a pivotal time when academic and personal experiences affect the development of student attitudes towards STEM (Christensen et al., 2015; Moreno et al., 2016). Teachers often utilize hands-on activities to promote student engagement with science curriculum (Brooks & Poles, 2021; Christensen et al., 2015). Hands-on activities improve student learning, but impacts vary by type of activity. When students work towards a known outcome they can feel disconnected from the work …

Tissue Kallikrein 1 Cleaves Complement Factor C3 And Activates The Alternative Complement Pathway, Sarah E. Sartain, Andrew Yee, Paula Jacobi Jan 2025

Tissue Kallikrein 1 Cleaves Complement Factor C3 And Activates The Alternative Complement Pathway, Sarah E. Sartain, Andrew Yee, Paula Jacobi

Research Data

Hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA), characterized by microvascular endothelial damage and severe renal injury, negatively affects HSCT survivorship with high mortality and long-term renal morbidity. After HSCT, innate immunity and inflammation are often dysregulated. The alternative complement pathway (AP) of the innate immune system is overactivated in HSCT-TMA, but the mechanisms of its initiation are poorly described. Complement component C3 of the AP can be cleaved by proteases outside of the AP. Because mRNA expression of tissue kallikrein 1 (KLK1), an inflammatory serine protease that produces kinins, has been found to be markedly elevated in the renal endothelium …

Comparison Of Hoop Nets To Trap Nets In Sampling Panfish, Jayden R, Alsleben Jan 2025

Comparison Of Hoop Nets To Trap Nets In Sampling Panfish, Jayden R, Alsleben

Journal of Earth and Life Science

Panfish including bluegill Lepomis macrochirus and black crappie Pomoxis nigromaculatus are gamefish species of significance found in Minnesota. Hoop nets and trap nets are two types of gear that can be used to sample these fish. Fisheries managers and anglers alike are interested in the best tactics to capture panfish. The behavior of fish, including bluegill and black crappie, change throughout the sampling season and make it difficult to assume accurate representations. Trap nets have historically been adequate in sampling near shore populations, but questions surrounding the gear have allowed other options to be pursued. The objective of this study …

The Effectiveness Of The Minnesota Buffer Law And Its Impacts On People, Ellen P. Isakson

Journal of Earth and Life Science

In January 2015, the then-governor of Minnesota Mark Dayton announced new legislation that would require 50-foot vegetation buffers along all waterways in Minnesota; this legislation would come to be known as the Minnesota buffer law, exact requirements being “perennial vegetative buffers of up to 50 feet along lakes, rivers, and streams and buffers of 16.5 feet along ditches” (Albert, 2017; MN Board of Water and Soil Resources [MN BWSR] 4 ). A buffer in the context of vegetation and natural resource management is a strip of vegetation around a body of water “designed to intercept stormwater runoff and minimize soil …

Age Class Is Not Related To Size Or Composition Of Home Ranges Among Suburban White-Tailed Deer During Parturition, Nathan D. Pyburn Jan 2025

Age Class Is Not Related To Size Or Composition Of Home Ranges Among Suburban White-Tailed Deer During Parturition, Nathan D. Pyburn

Journal of Earth and Life Science

How white-tailed deer use the landscape in an urban environment can help us understand the effects of urbanization on deer populations. White-tailed deer form observable matriarchal hierarchies in studied populations. This study examines the matriarchal structure, home range size, and home range composition of 25 collared white-tailed deer within the city limits of Bemidji, MN. The results found no significant difference between age class and home range size or composition. However, movement metrics from yearling and mature age classes were more similar than the juvenile age class females. I propose this is because social acceptance between mature females was higher …

The Influence Of Flower-Microbe Interactions On Bumble Bee Behavior And Gut Microbiome Composition, Success Chiamaka Ekemezie Jan 2025

The Influence Of Flower-Microbe Interactions On Bumble Bee Behavior And Gut Microbiome Composition, Success Chiamaka Ekemezie

Graduate Theses/Dissertations

This thesis examines how microbial interactions in floral nectar and environmental variation influence bumble bee (Bombus spp.) foraging behavior and gut microbiome composition. Pollen germination experiments and behavioral assays in the lab tested whether Metschnikowia reukaufii (yeast) and Acinetobacter nectaris (bacteria) induce pollen germination and bursting in nectar and affect bee behavior subsequently. Both microbes reduced intact pollen, but bees did not alter flower preference. Furthermore, the study also assessed how floral and bee community composition shaped gut microbiome composition across six Missouri prairies. Using amplicon-sequenced fungal ITS and bacterial 16S rRNA genes, I found that fungal microbiome composition varied …

Territorial Behavior Of A Terrestrial Salamander: Effect Of Physical Stress, Residency Status, And Sex, Abigail C. Nagl Jan 2025

Territorial Behavior Of A Terrestrial Salamander: Effect Of Physical Stress, Residency Status, And Sex, Abigail C. Nagl

Graduate Theses/Dissertations

Environmentally induced stressors can include threats from predators and competitors. Individuals in territorial species, including the subject of this study, Southern Red-backed Salamanders, Plethodon serratus, face ongoing competitive threats, and loss of contests may be more consequential to territory owners (losing a territory) than to intruders (continuing to be without a territory). Therefore, when the threat of increased predation risk is added, residents may respond differently than intruders. Here, I tested the impact of physical stress, residency status and sex on the territorial behavior of Southern Red-backed salamanders. Territorial behavior was assessed through staged contests with same-sized and same-sexed individuals, …

Inoculating Soybean Plants At Different Growth Stages: Selecting Bradyrhizobium, Sinorhizobium, Or Both, Matthew R. Knoll Jan 2025

Inoculating Soybean Plants At Different Growth Stages: Selecting Bradyrhizobium, Sinorhizobium, Or Both, Matthew R. Knoll

Graduate Theses/Dissertations

Soybean plants rely on nitrogen for growth, however atmospheric nitrogen (N2) is not a usable form and needs to be converted into different forms that are available to the plant. Nitrogen fixing bacteria such as rhizobia form symbiotic relationships with Soybeans in exchange for shelter and excess plant sugars. As a result, the plant can get the nitrogen it needs. There are four main genera of rhizobia that can form root nodules on Soybean including Bradyrhizobium, Sinorhizobium, Mesorhizobium, and Rhizobium. At this point, the effect that age of the host plant has on the selection of …

The Role Of Host Factor Sptbn1 In Hiv-1 Capsid Uncoating In Human Microglial Cells, Callie Marie Fry Jan 2025

The Role Of Host Factor Sptbn1 In Hiv-1 Capsid Uncoating In Human Microglial Cells, Callie Marie Fry

Graduate Theses/Dissertations

HIV-1 is the virus that causes acquired immunodeficiency syndrome (AIDS), and currently, there is no cure once an individual is infected. The development of new drugs targeting HIV-1 replication steps is essential for keeping viral loads low or undetectable to prevent further transmission. An attractive replication step for new drug targets is viral capsid uncoating, where the virus loses the protein structure encapsulating the genome. The exact mechanism of capsid uncoating is unknown; however, several host-factors may be involved including protein SPTBN1. Recent studies have shown a significant decrease in viral infectivity when SPTBN1 is knocked down, yet its role …

Editorial: The Development And Evolution Of Larval Nervous Systems, Oliver Vöcking, Allan Carrillo-Baltodano, Néva Meyer Jan 2025

Editorial: The Development And Evolution Of Larval Nervous Systems, Oliver Vöcking, Allan Carrillo-Baltodano, Néva Meyer

Biology

Throughout their development, animals of various taxa go through different larval stages, which have evolved adaptations to interact with specific environments. Larval nervous systems in particular experience strong selection pressures since they control crucial physiological and behavioral processes, especially in taxa with planktotrophic larvae that need to acquire food. Selection pressures also can vary across life history stages if there are differences in factors such as habitat, predation avoidance, and diet. There is evidence for this in the relationship of the larval nervous system to the adult nervous system, which can vary widely between species. Understanding the specific adaptations of …

Phylogenetic Proximity Is A Key Driver Of Temporal Succession Of Marine Giant Viruses In A Five-Year Metagenomic Time-Series, Sarah M. Laperriere, Benjamin Minch, J.L. Weissman, Shangwei Hou, Yi-Chun Yeh, Nathan Ahlgren, Mohammad Moniruzzaman

Biology

Nucleocytoplasmic large DNA viruses (NCLDVs), also called giant viruses, are widespread in marine systems and infect a broad range of microbial eukaryotes (protists). Recent biogeographic work has provided global snapshots of NCLDV diversity and community composition across the world’s oceans, yet little information exists about the guiding “rules” underpinning their community dynamics over time. We leveraged a five-year monthly coupled metagenomic-viromic time-series to quantify the community composition of NCLDVs off the coast of Southern California and characterize their temporal population dynamics. NCLDVs were dominated by Algavirales (Phycodnaviruses, 59%) and Imitervirales (Mimiviruses, 36%). We identified clusters of NCLDVs with distinct classes …

Characterization Of Fungal Carbonyl Sulfide Hydrolase Belonging To Clade D Β-Carbonic Anhydrase, Ryuka Iizuka, Takahiro Ogawa, Rikako Tsukida, Keiichi Noguchi, David Hibbett, Yoko Katayama, Makoto Yoshida

Biology

Carbonyl sulfide hydrolase (COSase) is a unique enzyme that exhibits high activity towards carbonyl sulfide (COS) but low carbonic anhydrase (CA) activity, despite belonging to the CA family. COSase was initially identified in a sulfur-oxidizing bacterium and later discovered in the ascomycete Trichoderma harzianum strain THIF08. The COSase from T. harzianum has been recognized as a key enzyme in the assimilation of gaseous COS, and homologous genes are widely present not only in Ascomycota but also in Basidiomycota. Here, we characterized the COSases from the basidiomycete Gloeophyllum trabeum NBRC 6430 and T. harzianum to obtain detailed characteristics of fungal COSase. …

Biology

The Drosophila PAX6 homolog twin of eyeless (toy) sits at the pinnacle of the genetic pathway controlling eye development, the retinal determination network. Expression of toy in the embryo is first detectable at cellular blastoderm stage 5 in an anterior–dorsal band in the presumptive procephalic neuroectoderm, which gives rise to the primordia of the visual system and brain. Although several maternal and gap transcription factors that generate positional information in the embryo have been implicated in controlling toy, the regulation of toy expression in the early embryo is currently not well characterized. In this study, we adopt an integrated experimental …
