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

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 …

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 …

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 …

Weak Spatial-Genetic Structure In A Native Invasive, The Southern Pine Beetle (Dendroctonus Frontalis), Across The Eastern United States, Ryan C. Garrick, Ísis C. Arantes, Megan B. Stubbs, Nathan P. Havill
Faculty and Student Publications
The southern pine beetle, Dendroctonus frontalis, is a native pest of pine trees that has recently expanded its range into the northeastern United States. Understanding its colonization, dispersal, and connectivity will be critical for mitigating negative economic and ecological impacts in the newly invaded areas. Characterization of spatial-genetic structure can contribute to this; however, previous studies have reached different conclusions about regional population genetic structure, with one study reporting a weak east-west pattern, and the most recent reporting an absence of structure. Here we systematically assessed several explanations for the absence of spatial-genetic structure. To do this, we developed nine …

The Effect Of Sampling Density And Study Area Size On Landscape Genetics Inferences For The Mississippi Slimy Salamander (Plethodon Mississippi), Stephanie M. Burgess, Ryan C. Garrick
Faculty and Student Publications
In landscape genetics, it is largely unknown how choices regarding sampling density and study area size impact inferences upon which habitat features impede vs. facilitate gene flow. While it is recommended that sampling locations be spaced no further apart than the average individual's dispersal distance, for low-mobility species, this could lead to a challenging number of sampling locations, or an unrepresentative study area. We assessed the effects of sampling density and study area size on landscape genetic inferences for a dispersal-limited amphibian, Plethodon mississippi, via analysis of nested datasets. Microsatellite-based genetic distances among individuals were divided into three datasets representing …

Purification Of Pcbp2 And Its Effect On The Formation Of Dna I-Motifs And Secondary Structures, Nathan Redden
Honors Theses
Several secondary, non-B forms of DNA are associated with the promoter regions of many oncogenes, including the intensely studied c-MYC gene that codes for a transcription factor. Two such secondary structures, G-quadruplexes, and i-motifs, have become topics of interest due to their prevalence within oncogenic promoters, as well as their potential accessibility for drug targeting. B-form DNA can adopt alternative structures under certain conditions. These alternative structures are favored when there is an asymmetric distribution of guanosine and cytosine on complimentary DNA strands. The strand rich in guanosine is able to form a quadruple stranded DNA complex termed a G-quadruplex. …

Effects Of Crowding Agents On I-Motif Dna, Hayden Brines
Honors Theses
Deoxyribonucleic acid (DNA) is a well-known double stranded, helical, biological molecule. In addition to its more commonly known structure, DNA can also form more complicated structures like G-quadruplexes and i-motifs (iM). The iMs are formed by cytosine rich DNA and are a four stranded structure that is typically looped around itself. The iM formation is typically pH-dependent and is favored in more acidic conditions; the pKa value is approximately 6.5. This pKa value allows for potential in vivo formation, since the cells have a pH of approximately 7.3. Due to this, iMs are thought to be powerful, innovative molecules for …

Honors Theses
Osteoarthritis and other debilitating diseases cause chronic pain that is difficult to manage. Nonsteroidal Anti-inflammatory Drugs (NSAIDs) are the current standard of treatment for many long-term pain management, but there are potential systemic effects when using NSAIDs long-term. Therefore, it isnecessary to have an alternative option for NSAID delivery that doesn’t include these systemic effects. Hydrogels can be that alternative option. Hydrogels’ distinct characteristics allow them to be viable in the body, degrade under unique conditions, and be modified through many different chemistries. Additionally, hydrogels can be engineered and their properties optimized for the use as a drug depot inside …
Chemical And Co-Solute Effects Of Polyethylene Glycol On I-Motif Formation, Lindsey Rutherford
Chemical And Co-Solute Effects Of Polyethylene Glycol On I-Motif Formation, Lindsey Rutherford
Honors Theses
DNA typically forms Watson and Crick double helix structures in which adenine, thymine, guanine, and cytosine pair with their complimentary DNA base. However, DNA i-motif structures can form in cytosine rich DNA, typically under slightly acidic conditions (~pH 6). DNA i-motifs are four stranded secondary structures in which cytosine pairs with cytosine to form a quadruplex. The i-motifs are typically formed in acidic conditions because of the protonation in the C•C base pair between one of the three hydrogen bases. Recent studies have suggested i-motifs can also form under neutral conditions, which is more realistic for a cell. It is …
