Assessing The Feasibility Of Seaweed Farm-Offshore Wind Co-Location In New Jersey, Brianna Delaney Reynolds 2024 Montclair State University

Assessing The Feasibility Of Seaweed Farm-Offshore Wind Co-Location In New Jersey, Brianna Delaney Reynolds

Theses, Dissertations and Culminating Projects

New Jersey’s offshore wind energy sector may provide an opportunity to advance the seaweed farming industry through ocean multi-use. Yet, opportunities, constraints, and knowledge gaps for seaweed farm-offshore wind co-location remain largely uninvestigated. Here, I determine the suitability of native seaweed species for offshore cultivation in New Jersey and conduct a quick scoping review (QSR) to assess the knowledge base surrounding seaweed farm-offshore wind multi-use. Saccharina latissima and Fucus vesiculosus were identified as native species with commercial value for cultivation in New Jersey. Yet, offshore waters at the location of a wind development site had insufficient nutrients to meet the …


C. Compactum Acts As A Comprehensive Climate Archive And Ecological Foundation In The Labrador Sea, Sadie Heckman 2024 Claremont Colleges

C. Compactum Acts As A Comprehensive Climate Archive And Ecological Foundation In The Labrador Sea, Sadie Heckman

CMC Senior Theses

Clathromorphum compactum, a species of crustose coralline algae (CCA), is incredibly valuable for the future of high latitude ocean health, both as a comprehensive archive of changing ocean conditions, and ecologically as a foundational species for promoting biodiversity. Previous work establishes C. compactum as an effective climate proxy, and its life history provides several advantages for this use. C. compactum grow in nongeniculate, generally radial formations on hard substrates, over a wide distribution in mid-to-high latitude oceans and at subtidal depth ranges. Indeterminate growth leads to extreme longevity in C. compactum (Halfar et al., 2008), and growth rates are relatively …

Complex Dynamics Of Coral Gene Expression Responses To Low Ph Across Species, Veronica Z. Radice, Ana Martinez, Adina Paytan, Donald C. Potts, Daniel J. Barshis

Biological Sciences Faculty Publications

Coral capacity to tolerate low pH affects coral community composition and, ultimately, reef ecosystem function. Low pH submarine discharges (‘Ojo’; Yucatán, México) represent a natural laboratory to study plasticity and acclimatization to low pH in relation to ocean acidification. A previous >2‐year coral transplant experiment to ambient and low pH common garden sites revealed differential survivorship across species and sites, providing a framework to compare mechanistic responses to differential pH exposures. Here, we examined gene expression responses of transplants of three species of reef‐building corals (Porites astreoides, Porites porites and Siderastrea siderea) and their algal endosymbiont communities …

Dynamic Genomic Evolution Via Active Ltr Transposable Elements In Maize, Taylor Isles 2024 Montclair State University

Dynamic Genomic Evolution Via Active Ltr Transposable Elements In Maize, Taylor Isles

Theses, Dissertations and Culminating Projects

Long terminal repeats (LTR) retrotransposons, found across eukaryotes, are transposable elements which can copy and insert themselves into other loci within a genome. These transposable elements are similar to retroviruses in that they rely on reverse transcriptase to “copy and paste” themselves elsewhere in the genome. From the RNA transcript they are able to use reverse transcriptase to make another DNA copy of themselves. This initially gave them the moniker, selfish genes. However, in the decades after the discovery of reverse transcriptase and LTR retrotransposons, it became known that non-genic DNA could have other functions. LTR retrotransposons are sources of …


Translation Of: Trembley À Réaumer, Abraham Trembley, Morgan McLaughlin 2024 University of San Diego

Translation Of: Trembley À Réaumer, Abraham Trembley, Morgan Mclaughlin

Biology: Student Scholarship & Creative Works

While examining a jar filled with aquatic plants and animals, Abraham Trembley, a young tutor working for Count William Bentinck in the Netherlands, noticed tiny, green, tube-shaped organisms attached to aquatic plants. Uncertain whether they were plants or animals, he devised a brilliant series of experiments to understand their biology. He observed them contract when disturbed and take steps towards a light, gathering in front of a chevron-shaped opening in a piece of cardboard. Nearly convinced they were animals, he cut one in half expecting to see it die. Instead, it regenerated two perfectly formed bodies from the severed halves. …

Michigan Tech Publications, Part 2

Vetiver root is widely used to produce essential oils in the aromatherapy industry. After the extraction of oil, the roots are disposed of as waste. The central objective of this research was to explore the conversion of this waste into a resource using a circular economy framework. To generate biochar, vetiver roots were pyrolyzed at different temperatures (300, 500, and 700 °C) and residence times (30, 60, and 120 min). Analysis showed the root biochar generated at 500 °C and held for 60 min had the highest surface area of 308.15 m2/g and a yield of 53.76%, in addition to …


Comparing Ionoregulation And Modes Of Nitrogen Excretion Across The Life Cycle Of Parasitic And Non-Parasitic Lamprey Species, Shannon Davidson 2024 Wilfrid Laurier University

Comparing Ionoregulation And Modes Of Nitrogen Excretion Across The Life Cycle Of Parasitic And Non-Parasitic Lamprey Species, Shannon Davidson

Theses and Dissertations (Comprehensive)

Abstract

Ionoregulation and nitrogenous waste (N-waste) metabolism in fishes has been extensively documented in teleosts and elasmobranchs, but less so in lampreys (Petromizontiformes). All lamprey species undergo metamorphosis which drastically changes their physiology and modes of feeding. However, differences in ionoregulatory mechanisms due to anadromous versus non anadromous life history strategies emerge following metamorphosis in different lamprey species. Furthermore, some species, such as anadromous juvenile sea lamprey (Petromyzon marinus), are parasitic and migrate to seawater (SW) to ingest blood protein from host fishes, while juveniles of freshwater (FW), non-parasitic species, such as the American brook lamprey …

In addition to its role in genome protection, DNA methylation can regulate gene expression. In this study, we characterized the impact of acidity, phase variation, and the ArsRS TCS on the expression of the Type I m6A DNA methyltransferase HsdM1 (HP0463) of Helicobacter pylori 26695 and their subsequent effects on the methylome. Transcription of hsdM1 increases at least fourfold in the absence of the sensory histidine kinase ArsS, the major acid-sensing protein of H. pylori. hsdM1 exists in the phase-variable operon hsdR1-hsdM1. Phase-locking hsdR1 (HP0464), the restriction endonuclease gene, has significant impacts on the transcription of hsdM1. To determine the …


Upa-Mediated Polyamidoamine Dendrimer-Based Targeted Gene Delivery System On Triple-Negative Breast Cancer, Hsin-Yin Chuang 2024 Missouri University of Science and Technology

Upa-Mediated Polyamidoamine Dendrimer-Based Targeted Gene Delivery System On Triple-Negative Breast Cancer, Hsin-Yin Chuang

Masters Theses

"Around 15% of breast cancers are triple-negative breast cancer (TNBC), which is characterized by the absence of three common receptors—ER, PR, and HER2, and therefore do not respond to hormonal or anti-HER2 therapies. It is urgent to explore targeted therapeutic strategies for TNBC due to its poor prognosis and rare effective targeted therapy. In this study, we developed a polyamidoamine (PAMAM) dendrimer-based targeted gene delivery system—GDP-uPA, to utilize urokinase-type plasminogen activator (uPA) to target uPA receptor (uPAR), which is highly expressed in both TNBC cells and cancer-associated stromal cells. Our results of 1H NMR spectrum, TEM imaging, and MTT assay …


Avian Extraembryonic Membranes Respond To Yolk Corticosterone Early In Development, Emily P. Harders, Mitch Agustin, Ryan T. Paitz 2024 Illinois State University

Avian Extraembryonic Membranes Respond To Yolk Corticosterone Early In Development, Emily P. Harders, Mitch Agustin, Ryan T. Paitz

Faculty Publications – Biological Sciences

During times of maternal stress, developing embryos can be exposed to elevated levels of glucocorticoids which can affect development and permanently alter offspring phenotype. In placental species, the placenta mediates fetal exposure to maternal glucocorticoids via metabolism, yet the placenta itself responds to glucocorticoids to regulate offspring growth and development. In oviparous species, maternal glucocorticoids can be deposited into the egg yolk and are metabolized early in development. This metabolism is mediated by the extraembryonic membranes, but it is unknown if the extraembryonic membranes also respond to maternal glucocorticoids in a way comparable to the placenta. In this study, we …


Assessing Endophyte Frequency Distributions And The Effect Of Epichloë Brachyelytri In The Chemotypic And Genotypic Diversity Of Brachyelytrum Erectum, Rachel Ann Sneed 2024 University of Kentucky

Assessing Endophyte Frequency Distributions And The Effect Of Epichloë Brachyelytri In The Chemotypic And Genotypic Diversity Of Brachyelytrum Erectum, Rachel Ann Sneed

Theses and Dissertations--Plant Pathology

Seed-transmissible epichloid fungal endophytes are best known for their roles as defensive mutualists in cool-season grasses. Historically, the discovery of fungal endophytes was driven by investigations of plant toxicity to livestock, followed by extensive study of their alkaloids and protection against insects and nematodes. Epichloae can produce four classes of alkaloids: ergot alkaloids, lolines (saturated aminopyrrolizidines), indole–diterpenes, and peramine. It is increasingly evident that these hereditary symbionts have much more diverse chemical profiles both in individual populations and between them. To this end, differences in chemotypic profiles of these symbionts may translate to different evolutionary and environmental advantages across plant …

Biogeographic Affiliation And Centers Of Richness As Predictors Of Elevational Range-Size Patterns For Malesian Flora, Melissa Whitman, Sabrina E. Russo

School of Biological Sciences: Faculty Publications

Our goal was to interrogate the idea that “mountain passes are higher in the tropics” by investigating ecological and biogeographic drivers of elevational range-sizes patterns among equatorial flora. We used herbarium records for 60 species-rich plant families, representing 18 535 species total, to estimate distributions over a 4500 m elevational gradient. For each family, we estimated the change in average range-sizes with increasing elevation (i.e. Rapoport's rule, abbreviated as ERR) and quantified 15 metrics of familial richness distribution, evolutionary age, and biogeographic affiliation. We visualized covariation across families using phylogenetic principal components analysis (pPCA). We then evaluated how family-level ERR …

Herbivores play a crucial role in shaping tundra ecosystems through their effects on vegetation, nutrient cycling, and soil abiotic factors. Understanding their habitat use, co-occurrence, and overlap is therefore essential for informing ecosystem-based management and conservation. In the High Arctic, only a marginal proportion of the land area is vegetated, and climate change is impacting herbivore population sizes and their habitats. In this study, we assessed the spatial habitat overlap of a vertebrate herbivore community based on: 1) regional predictive summer habitat suitability models for the resident Svalbard reindeer (Rangifer tarandus platyrhynchus), resident Svalbard rock ptarmigan (Lagopus …


The Role Of Semaphorins In Response To Injury In C. Elegans Neurons, Maria Belen Harreguy Alfonso 2023 New Jersey Institute of Technology

The Role Of Semaphorins In Response To Injury In C. Elegans Neurons, Maria Belen Harreguy Alfonso

Dissertations

When neural tissue is injured by trauma, delicate neuronal processes such as axons and dendrites are prone to lesion damage and often disconnect. The molecular, cellular, and circuit mechanisms that underlie the regrowth and reconnection of these processes and the recovery of behavior are major challenges in the fields of neuroscience, regeneration, and resilience. At the molecular and cellular levels, signaling pathways that mediate neuronal growth cone guidance during development can play a role in neuronal regeneration and recovery from injury. One family of signaling proteins involved in this process comprises the highly conserved semaphorins and their receptors, the plexins. …

Suma: A Lightweight Machine Learning Model Powered Shared Nearest Neighbour Based Clustering Application Interface Of Scrna-Seq, Hamza Umut Karakurt, Pınar Pir

Turkish Journal of Biology

Background/aim: Single-cell transcriptomics (scRNA-Seq) explores cellular diversity at the gene expression level. Due to the inherent sparsity and noise in scRNA-Seq data and the uncertainty on the types of sequenced cells, effective clustering and cell type annotation are essential. The graph-based clustering of scRNA-Seq data is a simple yet powerful approach which presents data as a “shared nearest neighbour” graph and clusters the cells using graph clustering algorithms. These algorithms are dependent on several user-defined parameters. Here we present SUMA, a lightweight tool that uses a random forest model to predict the optimum number of neighbours to have the optimum …

Physicochemical Differences Between Camelid Single-Domain Antibodies And Mammalian Antibodies, Nazli Eda Eski̇er, Doğa Eski̇er, Esi̇n Fi̇ruzan, Si̇bel Kalyoncu

Turkish Journal of Biology

Background/aim: In recent years, single-domain antibodies, also known as nanobodies, have emerged as an alternative to full immunoglobulin Gs (IgGs), due to their various advantages including increased solubility, faster clearance, and cheaper production. Nanobodies are generally derived from the variable domain of the camelid heavy-chain-only immunoglobulin Gs (hcIgGs). Due to the high sequence homology between variable heavy chains of camelids (VHHs) and humans (VHs), hcIgGs are ideal candidates for nanobody development. However, further examination is needed to understand the structural differences between VHs and VHHs. This analysis is essential for nanobody engineering to mitigate potential immunogenicity while preserving stability, functionality, …
