Does the Density of Invasive Rusty Crayfish Affect Stream Macroinvertebrates?

Rusty crayfish (_Orconectes rusticus_) have invaded streams of the upper Susquehanna River catchment (New York, USA), replacing native crayfish and probably increasing overall crayfish density. Crayfish are important consumers and agents of disturbance in aquatic communities, so the introduction and expansion of rusty crayfish could affect the invaded community through the change in crayfish species composition, the increase in crayfish density, or some combination of the two. Other macroinvertebrates are prey of, competitors with, or subject to disturbance by crayfish and so are likely to be affected by changes in the crayfish assemblage. We conducted correlative field sampling and an enclosure experiment to investigate the effects of invading _O. rusticus_ on the abundance, diversity, and composition of the stream macroinvertebrate assemblage. We sampled crayfish and macroinvertebrates at 13 sites on 4 streams in the upper Susquehanna River catchment that varied in crayfish species composition and density. Total macroinvertebrate abundance, taxon richness, diversity, and density of individual taxa were not significantly correlated to either total crayfish density or the relative abundance of _O. rusticus_. We also conducted an experiment in stream enclosures to test the effects of _O. rusticus_ density on the macroinvertebrate assemblage. Increasing crayfish density caused a significant decrease in total macroinvertebrate density but did not significantly affect macroinvertebrate taxon richness or diversity. The density of some individual taxa were also significantly affected by crayfish density. Our experiment shows that rusty crayfish density can affect the stream community; the mechanism of these effects, and whether they differ from those of native species, remain to be determined

Thermocrinis minervae sp. nov., A Hydrogen and Sulfur-oxidizing, Thermophilic Member of the Aquificales from a Costa Rican Terrestrial Hot Spring

A thermophilic bacterium, designated strain CR11T , was isolated from a filamentous sample collected from a terrestrial hot spring on the south-western foothills of the Rincón volcano in Costa Rica. The Gram-negative cells are approximately 2.4–3.9 mm long and 0.5–0.6 mm wide and are motile rods with polar flagella. Strain CR11T grows between 65 and 85 6C (optimum 75 6C, doubling time 4.5 h) and between pH 4.8 and 7.8 (optimum pH 5.9–6.5). The isolate grows chemolithotrophically with S0 , S2O2{ 3 or H2 as the electron donor and with O2 (up to 16 %, v/v) as the sole electron acceptor. The isolate can grow on mannose, glucose, maltose, succinate, peptone, Casamino acids, starch, citrate and yeast extract in the presence of oxygen (4 %) and S0 . Growth occurs only at NaCl concentrations below 0.4 % (w/v). The G+C content of strain CR11T is 40.3 mol%. Phylogenetic analysis of the 16S rRNA gene sequence places the strain as a close relative of Thermocrinis ruber OC 1/4T (95.7 % sequence similarity). Based on phylogenetic and physiological characteristics, we propose the name Thermocrinis minervae sp. nov., with CR11T (5DSM 19557T 5ATCC BAA-1533T ) as the type strain

Redefining Wellness among Asian American College Students at a Predominantly White Institution through AsianCrit Counter-Storytelling

The dominant narrative of Asian Americans in higher education is one of high achievement, success, and wellness. Dominant voices of white supremacy have primarily constructed this narrative. Asian Americans are regarded as the model minority or the dichotomous “model” while simultaneously maintaining “minority” status. This study centers on seven Asian American college students’ conceptions of and experiences with wellness at a predominantly White institution. These stories are showcased using AsianCrit and the critical race methodology of counter-storytelling. They are situated using anti-oppressive frameworks and the dimensions of wellness in college. Counter-storytelling challenges the dominant narrative about marginalized communities by centering their voices and lived experiences. Findings contribute to higher education and college wellness disciplines by highlighting Asian American experiences, including their significant positioning and liminality in the racial order, and build upon research that works to give voice to the incredibly diverse communities and cultures categorized as Asian American. Their counterstories reveal the cultural assets students bring to navigate racialized wellness experiences, their resilience through community, the deep impact of institutional racism and performativity, colorblind approaches to health and wellness, and an overall mistrust of “the institution.” This study informs higher education administrators of the importance of listening to the often dismissed voices of Asian Americans, and the necessity of dismantling colorblind approaches to student wellness and support services.Key Words: College Students, Asian American, AsianCrit, Critical Race Theory, Wellness, Counter-storytellin

Poster Session

Abstracts Humanities Emma Beeler, Mississippi University for Women Adultery and Fidelity in the Lais of Marie de France Using both literary and historical analysis, I will examine contrasting depictions of adultery and fidelity within the lais written by 12th-century poet Marie de France. A lai is a type of narrative poem, ranging in length from 118 to 1184 lines. Many of Marie de France’s lais follow the literary trope known as courtly love; however, the reader is encouraged to sympathize with different characters depending on the lai. In some lais, the reader is encouraged to sympathize with the adulterous spouse, and in others, with the faithful spouse. To understand these different depictions, I will consider Medieval marriage law, church doctrine, and social factors, as well as literary aspects of the lais. Social Sciences Maddison Caldwell, Northeast Mississippi Community College Parenting Styles: Effects on Lifelong Growth This project will examine parenting styles and how each can affect lifelong development. The parenting styles authoritative, authoritarian, permissive, and uninvolved will be explored. This project will require extensive analysis through different studies and scholarly articles. Parenting styles affect a child’s behavior, social competence, personality, well-being, and career choices. A parent’s choice of a parenting style affects their child their whole entire life. The authoritative parenting style was found to be the most beneficial style that can be used by a parent, while the authoritarian style was prone to cause conflict within the family. When the permissive parenting style is used, children were found to not set boundaries for themselves. Lasty, the uninvolved parenting styles causes relationship difficulties the child inhibits. I will also include a graph to show and explain how the different styles affect different aspects of life. This project clearly explains the four parenting styles and how they affect lifelong development throughout a child’s life. MacKenzie Paul, Mississippi State University To Sweeten or Not to Sweeten: The Unique Impact of Emotional Support and Fatalism on Sugar Consumption Among Southeastern Native Americans In 2020, 14.8% of Mississippi adults and 12.6% of Louisiana adults reported having diabetes, as compared to the national average of 10.8%. Furthermore, Native Americans of Mississippi and Louisiana experience disproportionately higher diabetes prevalence at 38% and 34% respectively. Research has shown that excessive sugar consumption is associated with an increased risk of developing type-2 diabetes. Psychosocial variables such as chronic disease fatalism and emotional support may also influence diabetes self-care behaviors including food consumption patterns like sugar intake. Therefore, the objective of this study is to examine the impact of emotional support and fatalism on sugar consumption among Southeastern Native Americans. The Mississippi INBRE Telenutrition Center Community Health Assessment Survey was utilized to survey 368 adults from Mississippi and Louisiana. Eighty-one of the participants, who self-identified as Native American, were included in the study. A hierarchal linear regression analysis showed that increased emotional support was significantly related with reduced sugar consumption (β = -0.307, p = 0.004), and increased fatalism was significantly associated with elevated sugar consumption (β = 0.286, p = 0.007). More research is necessary to substantiate this relationship among a broader Southeastern Native American population and identify potential implications for diabetes management in this disparate group. STEM Shirli Salihaj, Mississippi University for Women Surface Reconstruction via the Curvature Interpolation Method The surface reconstruction for scattered data becomes a problem as the number of sample points increases to construct a continuous function that satisfies given conditions in three dimensions (3D). However, it is known that this problem does not have a definite solution and therefore requires numerical approximations. This project studies the Curvature Interpolation Method with Iterative Refinement (IR-CIM), an innovative algorithm that produces smooth and reliable surfaces from 3D point cloud data. I use pre-collected data by Light Detection and Ranging (LiDAR) technology and MATLAB to perform digital image processing. I first study interpolation on 2D data and then practice with 3D data sets with simple interpolation methods to practice the implementation of IR-CIM for LiDAR data. The research objective is to compare the efficiency and accuracy of the IR-CIM with the inverse distance weighting method. Furthermore, I will verify that the IR-CIM outperforms the inverse distance weighting method and show that it is a good alternative to replace the outdated algorithm when processing LiDAR data. Sara Lynn Sligh, Mississippi University for Women Effects of Chloride Ion Channel Activators on CFTR Expression The purpose of this research is to determine the effects of newly synthesized compounds, which have shown the ability to function as chloride ion channel activators, on the expression of Cystic Fibrosis Transmembrane-conductance Regulator (CFTR), a protein found within Cystic Fibrosis Bronchial Epithelial (CFBE) cells. Mutations in the CFTR protein cause the genetic disease Cystic Fibrosis (CF). To conduct this research, a tissue culture utilizing three main cell lines is being performed. The three main cell lines are CFBE-wild type, CFBE-ΔF508, and CFBE-41ø. CFBE-wildtype contains the normal, functional CFTR protein. CFBE-ΔF508 contains the nonfunctional CFTR protein as well as the mutation that is responsible for over 70% of CF cases. CFBE-41ø is the parental cell line and will function as a negative control. The main method used to determine the effects of the new compounds is Immunofluorescence Cytochemistry. Through this method, images are generated that identify the location of CFTR within the cell while maintaining the cell’s integrity. These experiments are being run weekly to generate data via images captured by an immunofluorescent microscope. Stephen Trest, Mississippi Gulf Coast Community College The Bonnet Carre Spillway and Its Effects on South Mississippi\u27s Economy The Bonnet Carre Spillway is a flood control system located in Saint Charles Parish, Louisiana. In recent years, this spillway has been opened longer and more often than it had in the past. As a result, there has been a much larger quantity of fresh water in the Mississippi Sound, and this has killed a large quantity of marine life. This seriously impacts our local fishing economy. Many fishers have had to take entire seasons off because it would not be profitable to operate in these conditions. On top of the effects on fishing, the excess fresh water contributes to the flesh-eating bacteria outbreak which has plagued our beaches for years. 2019 was the first time in history that the Bonnet Carre was opened twice in one year, and it was also a particularly bad year for flesh-eating bacteria on our beaches; tourism is a major industry on the coast, and the beach is the main reason for that. We need a healthy Mississippi Sound for our coastal economy to thrive, and the repeated flooding of fresh water through the Bonnet Carre is negatively affecting that. Since flooding New Orleans is not an option, I will go over the other possible solution: restoring the Mississippi River Delta

The atmospheres of the hot-Jupiters Kepler-5b and Kepler-6b observed during occultations with Warm-Spitzer and Kepler

This paper reports the detection and the measurements of occultations of the two transiting hot giant exoplanets Kepler-5b and Kepler-6b by their parent stars. The observations are obtained in the near infrared with Spitzer Space Telescope and at optical wavelengths by combining more than a year of Kepler photometry. The investigation consists of constraining the eccentricities of these systems and of obtaining broad band emergent spectra for individual planets. For both targets, the occultations are detected at 3 sigma level at each wavelength with mid-occultation times consistent with circular orbits. The brightness temperatures of these planets are deduced from the infrared observations and reach T=1930+/-100K and T=1660+/-120K for Kepler-5b and Kepler-6b respectively. We measure optical geometric albedos A_g in the Kepler bandpass and find A_g=0.12+/-0.04 for Kepler-5b and A_g=0.11+/-0.04 for Kepler-6b leading to an upper limit for the Bond albedo of A_B < 0.17 in both cases. The observations for both planets are best described by models for which most of the incident energy is redistributed on the dayside, with only less than 10% of the absorbed stellar flux redistributed to the night side of these planets. The data for Kepler-5b favor a model without a temperature inversion, whereas for Kepler-6b they do not allow distinguishing between models with and without inversion.Comment: 26 pages, 18 figures, 3 tables, submitted to Ap

Promotion of physical activity in rural, remote and northern settings: a Canadian call to action

Introduction: The lack of policy, practice and research action on physical activity and features of the physical (built and natural) environments in rural, remote and northern settings is a significant threat to population health equity in Canada. This paper presents a synthesis of current evidence on the promotion of physical activity in non-urban settings, outcomes from a national priority-setting meeting, and a preliminary call to action to support the implementation and success of population-level initiatives targeting physical activity in non-urban settings. Methods: We conducted a “synopses of syntheses” scoping review to explore current evidence on physical activity promotion in rural, remote, northern and natural settings. Next, we facilitated a collaborative priority-setting conference with 28 Canadian experts from policy, research and practice arenas to develop a set of priorities on physical activity in rural, remote and northern communities. These priorities informed the development of a preliminary Canadian call to action. Results: We identified a limited number of reviews that focused on physical activity and the built environment in rural, remote and northern communities. At the priority-setting conference, participants representing rural, remote and northern settings identified top priorities for policy, practice and research action to begin to address the gaps and issues noted in the literature. These priorities include self-identifying priorities at the community level; compiling experiences; establishing consistency in research definitions and methods; and developing mentorship opportunities. Conclusion: Coordinated action across policy, practice and research domains will be essential to the success of the recommendations presented in this call to action
