Patch Size Drives Colonization By Aquatic Insects, With Minor Priority Effects Of A Cohabitant, Reed C. Scott, Matthew R. Pintar, William J. Resetarits Dec 2021

Patch Size Drives Colonization By Aquatic Insects, With Minor Priority Effects Of A Cohabitant, Reed C. Scott, Matthew R. Pintar, William J. Resetarits

Faculty and Student Publications

Patch size is one of the most important factors affecting the distribution and abundance of species, and recent research has shown that patch size is an important niche dimension affecting community structure in aquatic insects. Building on this result, we examined the impact of patch size in conjunction with presence of larval anurans on colonization by aquatic insects. Hyla chrysoscelis (Cope's gray treefrog) larvae are abundant and early colonists in fishless lentic habitats, and these larvae can fill multiple ecological roles. By establishing larvae in mesocosms prior to colonization, we were able to assess whether H. chrysoscelis larvae have priority …


Spatial Distribution Of Conspecific Genotypes Within Chimeras Of The Branching Coral Stylophora Pistillata, Gabriele Guerrini, Dor Shefy, Jacob Douek, Nadav Shashar, Tamar L. Goulet, Baruch Rinkevich Dec 2021

Spatial Distribution Of Conspecific Genotypes Within Chimeras Of The Branching Coral Stylophora Pistillata, Gabriele Guerrini, Dor Shefy, Jacob Douek, Nadav Shashar, Tamar L. Goulet, Baruch Rinkevich

Faculty and Student Publications

Chimerism is a coalescence of conspecific genotypes. Although common in nature, fundamental knowledge, such as the spatial distribution of the genotypes within chimeras, is lacking. Hence, we investigated the spatial distribution of conspecific genotypes within the brooding coral Stylophora pistillata, a common species throughout the Indo-Pacific and Red Sea. From eight gravid colonies, we collected planula larvae that settled in aggregates, forming 2–3 partner chimeras. Coral chimeras grew in situ for up to 25 months. Nine chimeras (8 kin, 1 non-related genotypes) were sectioned into 7–17 fragments (6–26 polyps/fragment), and genotyped using eight microsatellite loci. The discrimination power of each …


Rcb Initiates Arabidopsis Thermomorphogenesis By Stabilizing The Thermoregulator Pif4 In The Daytime, Yongjian Qiu, Elise K. Pasoreck, Chan Yul Yoo, Jiangman He, He Wang, Abhishesh Bajracharya, Meina Li, Haley D. Larsen, Stacey Cheung, Meng Chen Dec 2021

Rcb Initiates Arabidopsis Thermomorphogenesis By Stabilizing The Thermoregulator Pif4 In The Daytime, Yongjian Qiu, Elise K. Pasoreck, Chan Yul Yoo, Jiangman He, He Wang, Abhishesh Bajracharya, Meina Li, Haley D. Larsen, Stacey Cheung, Meng Chen

Faculty and Student Publications

Daytime warm temperature elicits thermomorphogenesis in Arabidopsis by stabilizing the central thermoregulator PHYTOCHROME INTERACTING transcription FACTOR 4 (PIF4), whose degradation is otherwise promoted by the photoreceptor and thermosensor phytochrome B. PIF4 stabilization in the light requires a transcriptional activator, HEMERA (HMR), and is abrogated when HMR’s transactivation activity is impaired in hmr-22. Here, we report the identification of a hmr-22 suppressor mutant, rcb-101, which surprisingly carries an A275V mutation in REGULATOR OF CHLOROPLAST BIOGENESIS (RCB). rcb-101/hmr-22 restores thermoresponsive PIF4 accumulation and reverts the defects of hmr-22 in chloroplast biogenesis and photomorphogenesis. Strikingly, similar to hmr, the null rcb-10 mutant impedes …

Climate And Seasonality Drive The Richness And Composition Of Tropical Fungal Endophytes At A Landscape Scale, Shuzo Oita, Alicia Ibáñez, François Lutzoni, Jolanta Miadlikowska, József Geml, Louise A. Lewis, Erik F. Y. Hom, Ignazio Carbone, Jana M. U’Ren, A. Elizabeth Arnold

Faculty and Student Publications

Understanding how species-rich communities persist is a foundational question in ecology. In tropical forests, tree diversity is structured by edaphic factors, climate, and biotic interactions, with seasonality playing an essential role at landscape scales: wetter and less seasonal forests typically harbor higher tree diversity than more seasonal forests. We posited that the abiotic factors shaping tree diversity extend to hyperdiverse symbionts in leaves—fungal endophytes—that influence plant health, function, and resilience to stress. Through surveys in forests across Panama that considered climate, seasonality, and covarying biotic factors, we demonstrate that endophyte richness varies negatively with temperature seasonality. Endophyte community structure and …


Test Transferability Of 3d-Mot Training On Soccer Specific Parameters, Micaela Dusseault Dec 2021

Test Transferability Of 3d-Mot Training On Soccer Specific Parameters, Micaela Dusseault

Honors Theses

Objective: The benefits of perceptual-cognitive training in elite level athletes has recently been investigated in multiple sports such as basketball, soccer, and archery, but conclusive evidence proving test transferability of 3D-MOT training is lacking. The purpose of this research is to examine the transferability of perceptual-cognitive training to on-field soccer performance parameters. Participants: NCAA Division I women’s soccer players (n=22) between the ages of 18-25 who were placed into either the experimental group (n=10) or control group (n=12). After baseline testing for both groups to determine visual tracking speed (VTS), the experimental group completed 10 3D-MOT training sessions with NeuroTracker …

A Case For The Decriminalization Of Simple Possession Of Narcotics In Mississippi, Stroud Tolleson Dec 2021

A Case For The Decriminalization Of Simple Possession Of Narcotics In Mississippi, Stroud Tolleson

Honors Theses

Through its incarceration of simple possession offenders, Mississippi is failing to acknowledge the severity of addiction and importance of mental health. In this paper, I will examine Mississippi’s history of opinion and policy on drug use. In order to gain a better understanding of addiction and Mississippi’s criminal justice system, I interview several individuals with experience in varying aspects of these issues. Mississippi has one of the highest rates of incarceration in the United States, with stringent laws regarding the possession of narcotics. Mississippi’s mental health resources have been deemed unconstitutionally deficient on more than one occasion, and addicts are …


Mutants Of The White Abcg Transporter In Drosophila Melanogaster Have Deficient Olfactory Learning And Cholesterol Homeostasis, Jennifer L. Myers, Maria Porter, Nicholas Narwold, Krishna Bhat, Brigitte Dauwalder, Gregg Roman Nov 2021

Mutants Of The White Abcg Transporter In Drosophila Melanogaster Have Deficient Olfactory Learning And Cholesterol Homeostasis, Jennifer L. Myers, Maria Porter, Nicholas Narwold, Krishna Bhat, Brigitte Dauwalder, Gregg Roman

Faculty and Student Publications

Drosophila’s white gene encodes an ATP binding cassette G-subfamily (ABCG) half transporter. White is closely related to mammalian ABCG family members that function in cholesterol efflux. Mutants of white have several behavioral phenotypes that are independent of visual defects. This study characterizes a novel defect of white mutants in the acquisition of olfactory memory using the aversive olfactory conditioning paradigm. The w1118 mutants learned slower than wildtype controls, yet with additional training, they reached wildtype levels of performance. The w1118 learning phenotype is also found in the wapricot and wcoral alleles, is dominant, and is …

Faculty and Student Publications

There are numerous publications demonstrating that plant polyphenols can reduce oxi-dative stress and inflammatory processes in the brain. In the present study we have investigated the neuroprotective effect of plant extract isolated from the roots of L. gmelinii since it contains a rich source of polyphenols and other biologically active compounds. We have applied an oxidative and inflammatory model induced by NMDA, H2O2, and TNF‐α in human primary neurons and astrocytes, and mouse cerebral endothelial cell (CECs) line in vitro. The levels of ROS generation, NADPH oxidase activation, P‐selectin expression, and activity of ERK1/2 were evaluated by quan-titative immunofluorescence analysis, …

Expression Of Mhc Class I Polypeptide-Related Sequence A (Mica) In Colorectal Cancer, Ingrid Espinoza, Sumit Agarwal, Marcelo Sakiyama, Veena Shenoy

Faculty and Student Publications

Background: The major histocompatibility complex class I polypeptide-related sequence A (MICA) is one of the ligands of the natural killer group 2D (NKG2D) activating receptor. MICA stimulates NKG2D, which further triggers activation of natural killer cells and leads to killing of infected target cells. To subvert the biological function of NKG2D, tumor cells utilize an escape strategy by shedding overexpressed MICA. In this study, we determined the levels of MICA in colorectal cancers (CRCs). Additionally, we established correlations between MICA expression and clinical characteristics. Publicly available data and bioinformatics tools were used for validation purposes. Methods: We determined the MICA …
