Editorial: Deep Pelagic Ecosystem Dynamics In A Highly Impacted Water Column: The Gulf Of Mexico After Deepwater Horizon, Tracey Sutton, Kevin M. Boswell, Heather Bracken-Grissom, Jose V. Lopez, Michael Vecchione, Marsh Youngbluth

Marine & Environmental Sciences Faculty Articles

The intermediate-sized midwater fauna (fishes, shrimps, and cephalopods; “micronekton” collectively) are dominant components of the pelagic ocean, which is by far the largest ecosystem type on Earth by several metrics (volume, organismal numbers, biomass, and productivity). Deep-pelagic micronekton, those animals residing in the water column below 200 m depth during the day, are the direct link between plankton and oceanic top predators, and through the linked processes of feeding and daily vertical migration facilitate one of Earth's most important ecosystem services to humans, carbon sequestration. Despite increasing recognition of this importance, a disconnect exists between stewardship and human impact; only …

This review provides examples of various documented impacts, common patterns, and trends across organisms and/or their environments, and discusses future implications as well as directions for future research. Organism effects are generally characterized as lethal and sublethal. Sublethal can be short term, long term, or permanent and multigenerational. We present individual examples of effects on behavioral response, olfaction, vision, cardiac function, and gene shift, based on research done in laboratories, mesocosm settings, and the …

The Role Of Glutamine In Supporting Gut Health And Neuropsychiatric Factors, Brett J. Deters, Mir Saleem

Biology Faculty Articles

Recent research has shown that the amino acid glutamine can positively affect gut health by supporting the gut microbiome, gut mucosal wall integrity, and by modulating inflammatory responses. As modulated by the vagus nerve, via the enteric nervous system, the gut-brain connection can impact the brain's neurochemical environment. Poor gut health can disrupt the balance of neurotransmitters, which can result in neuropsychiatric based conditions such as depression. Glutamine supplementation may provide significant adjunctive nutritional support in cases of depression by promoting proper gut health and function.

Someone Else’S Child: A Co-Constructed, Performance Autoethnography Of Adoption From Three Perspectives, Robin L. Danzak, Christina Gunther, Michelle Cole

The Qualitative Report

Through a framework of reconciling the other, this collaborative autoethnographic performance co-constructs the adoption experience from three perspectives in three different families: a mother struggling with the ethical and emotional implications of the transnational adoption of her daughter; an adult reflecting on her childhood as an adoptee feeling loved, but different; and a woman who met her biological sister at age 28 after her parents revealed a lifelong secret. To develop individual adoption narratives, we applied autoethnographic tools of interactive interviews with family members, reflective writing, and document review (Ellis, 2004) of photos, letters, emails, and calendars. During one school …

Experiences Of Mothers Of Lgbtq Children In Serbia: What Comes After Coming Out?, Vedrana Mirković, Ivan Jerković

The Qualitative Report

Coming out process is a necessary step for a LGBTQ person in order to develop integrative sexual and transgender identity (Cass, 1984; Manning, 2014). and mental health of LGBTQ people is under strong influence by the family and social support and their reactions to coming out (D’Augelli, 2002; Ryan et al., 2010; Ryan, Legate, & Winstein, 2015). The goal of the present research is to explore what is the experience of mothers of LGBTQ children in Serbia after the children’s coming out? Using the Interpretative Phenomenological Analysis (Smith, 2015), this study explored the experience of eight mothers of LGBTQ youth …

Mathematics Faculty Articles

Discovering dominant epitopes for T cells, particularly CD4⁺ T cells, in human immune-mediated diseases remains a significant challenge. Here, we used bronchoalveolar lavage (BAL) cells from HLA-DP2-expressing patients with chronic beryllium disease (CBD), a debilitating granulomatous lung disorder characterized by accumulations of beryllium (Be)-specific CD4⁺ T cells in the lung. We discovered lung resident CD4⁺ T cells that expressed a disease-specific public CDR3β T cell receptor motif and were specific to Be-modified self-peptides derived from C-C motif ligands 4 (CCL4) and 3 (CCL3). HLA-DP2-CCL/Be tetramer staining confirmed that these chemokine-derived peptides represented major antigenic targets in CBD. …

State Of Satiation Partially Regulates The Dynamics Of Vertical Migration, Ryan P. Bos, Tracey Sutton, Tamara Frank

Marine & Environmental Sciences Faculty Articles

Vertical migrations into shallower waters at night are beneficial for migrators as they reduce predation risk and allow migrators to encounter a higher density of prey. Nevertheless, ocean acoustics data and trawl data have shown that a portion of some vertically migrating populations remain at depth and do not migrate. One hypothesis for this phenomenon is the Hunger-Satiation hypothesis, which in part states that the non-migrating portion of the migrating species-assemblage refrains from migrating if they have full or partially full stomachs from daytime or nocturnal feeding. However, stomach fullness of the non-migrating subpopulation compared to the migrating portion has …

Comparison Of A Smartfin With An Infrared Sea Surface Temperature Radiometer In The Atlantic Ocean, Robert J. W. Brewin, Werenfrid Wimmer, Phillip J. Bresnahan, Tyler Cyronak, Andreas J. Andersson, Giorgio Dall’Olmo

Marine & Environmental Sciences Faculty Articles

The accuracy and precision of satellite sea surface temperature (SST) products in nearshore coastal waters are not well known, owing to a lack of in-situ data available for validation. It has been suggested that recreational watersports enthusiasts, who immerse themselves in nearshore coastal waters, be used as a platform to improve sampling and fill this gap. One tool that has been used worldwide by surfers is the Smartfin, which contains a temperature sensor integrated into a surfboard fin. If tools such as the Smartfin are to be considered for satellite validation work, they must be carefully evaluated against state-of-the-art techniques …

The Pedagogical Representation Of Mass Functions With Lego And Their Origin, Stefan Kautsch

Chemistry and Physics Faculty Articles

We promote the teaching of mass functions as an integral part of an interdisciplinary science education. Mass functions characterize the frequency distributions of objects with different masses on all cosmic scales. We intend to enhance experiential learning of this concept with a creative LEGO brick experiment for a diverse student audience. To our surprise, the LEGO mass function is not only qualitatively but also quantitatively comparable to mass functions found across the universe. We also discuss the relation between gravitation and mass distributions as a possible explanation for the continuity of the universal mass function.

Microbiome Analyses Demonstrate Specific Communities Within Five Shark Species, Rachael Storo, Cole Easson, Mahmood S. Shivji, Jose V. Lopez

Biology Faculty Articles

Profiles of symbiotic microbial communities (“microbiomes”) can provide insight into the natural history and ecology of their hosts. Using high throughput DNA sequencing of the 16S rRNA V4 region, microbiomes of five shark species in South Florida (nurse, lemon, sandbar, Caribbean reef, and tiger) have been characterized for the first time. The microbiomes show species specific microbiome composition, distinct from surrounding seawater. Shark anatomical location (gills, teeth, skin, cloaca) affected the diversity of microbiomes. An in-depth analysis of teeth communities revealed species specific microbial communities. For example, the genus Haemophilus, explained 7.0% of the differences of the teeth microbiomes …

A Composite Textual Phenomenological Approach To Cures Versus Traditional Laboratory Experiences, Amie S. Sommers, Dana Richter-Egger, Christine E. Cutucache

The Qualitative Report

Here we present unique perspectives from undergraduate students (n=3) in STEM who have taken both a traditional laboratory iteration and a Course-based Undergraduate Research Experience (CURE) iteration of the same introductory chemistry course. CUREs can be effective models for integrating research in courses and fostering student learning gains. Via phenomenological interviews, we asked students to describe the differences in their perspectives, feelings, and experiences between a traditional lab guided by a lab manual and a CURE. We found that (i.) critical thinking/problem solving, (ii.) group work/collaboration, (iii.) student-led research questions and activities, and (iv.) time management are the top four …

Peace and Conflict Studies Journal Conference

This session is derived from the presenters Ph.D. dissertation research on examining the relationship between the high social need for conflict resolution and low social demand. Emily interviewed 30 millennials and 9 conflict resolution practitioners to evaluate language and social engagement and connection with marketing and branding of conflict resolution. The interviews painted a landscape of valleys of potential and uncharted territory of points of connection between the field and potential target markets. The research serves as an important tool for practitioners in evaluating their current practices and supporting strategic design of new practices by outlining gaps in language and …

Crises Beyond Nationalities, J P. Linstroth

Peace and Conflict Studies Journal Conference

The aim of my presentation titled, Crises Beyond Nationalities, is to discuss the topics of “immigration and racism”, “nationalism and terrorism”, “genocide”, “racial trauma”, “biology, neuroscience, and humanity”, and “empathy, love, and peace” so as not only to theorize about these complex issues but to point to ways forward with some progressive thinking. If the topics of “racism and immigration” are isolated without discussing their broader associations such as with nationalism and violence, or in the most extreme with genocide, then the arguments are not broad enough. As an anthropologist and peace activist, it is important to analyze such …

Power, Emotions, And Violent Conflicts, Daniel Rothbart

Peace and Conflict Studies Journal Conference

Hatred, fear, and disdain—these are emotions that drive conflict protagonists to commit acts of violence against their adversaries. Conventional thinking among conflict analysts holds that the private realm of negative emotions exhibited by conflict actors is distinct fundamentally from the public world of objective causal drivers of conflict, such as poverty, structural violence and proliferation of small arms. However, such conventional thinking regarding this inherent duality of emotions and power cannot for the social-psychic force of affect emotions that intersects with the conflict dynamics. In many conflict settings, the release of such a force is a political act, with the …

Discovery Of Molecular Interactions Of The Human Melanocortin-4 Receptor (Hmc4r) Asp189 (D189) Amino Acid With The Endogenous G-Protein-Coupled Receptor (Gpcr) Antagonist Agouti-Related Protein (Agrp) Provides Insights To Agrp's Inverse Agonist Pharmacology At The Hmc4r, Mark D. Ericson, Erica M. Haslach, Sathya M. Schnell, Katie T. Freeman, Zhimin M. Xiang, Frederico P. Portillo, Robert Speth, Sally A. Litherland, Carrie Haskell-Luevano

HPD Articles

The melanocortin receptors (MCRs) are important for numerous biological pathways, including feeding behavior and energy homeostasis. In addition to endogenous peptide agonists, this receptor family has two naturally occurring endogenous antagonists, agouti and agouti-related protein (AGRP). At the melanocortin-4 receptor (MC4R), the AGRP ligand functions as an endogenous inverse agonist in the absence of agonist and as a competitive antagonist in the presence of agonist. At the melanocortin-3 receptor (MC3R), AGRP functions solely as a competitive antagonist in the presence of agonist. The molecular interactions that differentiate AGRP's inverse agonist activity at the MC4R have remained elusive until the findings …

Biology Faculty Articles

The pelagic tunicate pyrosome, Pyrosoma atlanticum, is known for its brilliant bioluminescence, but the mechanism causing this bioluminescence has not been fully characterized. This study identifies the bacterial bioluminescent symbionts of P. atlanticum collected in the northern Gulf of Mexico using several methods such as light and electron microscopy, as well as molecular genetics. The bacteria are localized within the pyrosome light organs. Greater than 50% of the bacterial taxa present in the tunicate samples were the bioluminescent symbiotic bacteria Vibrionaceae as determined by utilizing current molecular genetics methodologies. A total of 396K MiSeq16S rRNA reads provided total pyrosome …

The Meaning Of “Phenomenology”: Qualitative And Philosophical Phenomenological Research Methods, Heath Williams

The Qualitative Report

I show some problems with recent discussions within qualitative research that centre around the “authenticity” of phenomenological research methods. I argue that attempts to restrict the scope of the term “phenomenology” via reference to the phenomenological philosophy of Husserl are misguided, because the meaning of the term “phenomenology” is only broadly restricted by etymology. My argument has two prongs: first, via a discussion of Husserl, I show that the canonical phenomenological tradition gives rise to many traits of contemporary qualitative phenomenological theory that are purportedly insufficiently genuine (such as characterisations of phenomenology as “what-its-likeness” and presuppositionless description). Second, I argue …

Functional Influence Of 14-3-3 (Ywha) Proteins In Mammals, Elizabeth Barley, Santanu De

Mako: NSU Undergraduate Student Journal

The 14-3-3 (YWHA) proteins are homologous, ubiquitous, and conserved in most organisms ranging from plants to animals and play important roles in regulating key cellular events such as cell signaling, development, apoptosis, etc. These proteins consist of seven isoforms in mammals, termed under Greek alphabetization: beta (β), gamma (γ), epsilon (ε), eta (η), tau/theta (τ), sigma (σ), and zeta (ζ). Each of these isoforms can interact with a plethora of binding partners and has been shown to serve a distinct role in molecular crosstalk, biological processes, and disease susceptibility. Protein 14-3-3 isoforms are scaffolding proteins capable of forming homodimers and …

Marine & Environmental Sciences Faculty Articles

The discovery of multi-species synchronous spawning of scleractinian corals on the Great Barrier Reef in the 1980s stimulated an extraordinary effort to document spawning times in other parts of the globe. Unfortunately, most of these data remain unpublished which limits our understanding of regional and global reproductive patterns. The Coral Spawning Database (CSD) collates much of these disparate data into a single place. The CSD includes 6178 observations (3085 of which were unpublished) of the time or day of spawning for over 300 scleractinian species in 61 genera from 101 sites in the Indo-Pacific. The goal of the CSD is …

Thermal Acclimation Of Tropical Coral Reef Fishes To Global Heat Waves, Jacob L. Johansen, Lauren E. Nadler, Adam Habary, Alyssa J. Bowden, Jodie Rummer

Marine & Environmental Sciences Faculty Articles

As climate-driven heat waves become more frequent and intense, there is increasing urgency to understand how thermally sensitive species are responding. Acute heating events lasting days to months may elicit acclimation responses to improve performance and survival. However, the coordination of acclimation responses remains largely unknown for most stenothermal species. We documented the chronology of 18 metabolic and cardiorespiratory changes that occur in the gills, blood, spleen, and muscles when tropical coral reef fishes are thermally stressed (+3.0°C above ambient). Using representative coral reef fishes (Caesio cuning and Cheilodipterus quinquelineatus) separated by >100 million years of evolution and …

An Autoethnographic Self-Study Navigating The Transition To Becoming A Stem Teacher Educator, Miriam Hamilton Dr

Using self-study, I explore how my habitus has influenced my experiences of being a biology teacher at second level to teaching STEM education on initial teacher education programmes. Autoethnographic self-study is the hybrid approach used to describe and systematically analyse my experiences and learning as I struggle with a transitioning identity. The integrated use of both self-study and autoethnographic approaches enabled a deepened understanding of my …

Evaluating The Use Of Marine Protected Areas By Endangered Species: A Habitat Selection Approach, Kelsey E. Roberts, Brian J. Smith, Derek Burkholder, Kristen M. Hart

Marine & Environmental Sciences Faculty Articles

1. Optimizing the design of marine protected area (MPA) networks for the conservation of migratory marine species and their habitats involves a suite of important considerations, such as appropriate scale requirements and the distribution of anthropogenic impacts. Often, a fundamental component of the conservation planning process is delineating areas of high use or high biodiversity within a region of interest.

2. However, basing conservation strategies off merely the number of individuals in an ecosystem is outdated and potentially subject to arbitrary thresholds. To be effective at protecting marine megafauna, MPAs would ideally encompass habitats used by focal species. Through satellite-tracking …
