Functional Trait Values, Not Trait Plasticity, Drive The Invasiveness Of Rosa Sp. In Response To Light Availability, Rebecca E. Drenovsky, Jennifer E. Murphy
Functional Trait Values, Not Trait Plasticity, Drive The Invasiveness Of Rosa Sp. In Response To Light Availability, Rebecca E. Drenovsky, Jennifer E. Murphy
Biology
PREMISE OF THE STUDY : Functional trait plasticity in resource capture traits has been suggested as an underlying mechanism promoting invasive species establishment and spread. Earlier studies on this mechanism treat invasiveness as a discrete characteristic (i.e., invasive vs. noninvasive) and do not consider the potential impacts of evolutionary history. In the present study, we used a continuous measure of invasiveness and a phylogenetic framework to quantify the relationship between functional trait expression, plasticity, and invasiveness in Rosa .

Phenotypic Plasticity And Population Differentiation In Response To Salinity In The Invasive Cordgrass Spartina Densiflora, Rebecca E. Drenovsky, Brenda J. Grewell, Jesus M. Castillo, Meghan J. Skaer Thomason
Biology
Salinity and tidal inundation induce physiological stress in vascular plant species and influence their distribution and productivity in estuarine wetlands. Climate change-induced sea level rise may magnify these abiotic stressors and the physiological stresses they can cause. Understanding the potential of invasive plants to respond to predicted salinity increases will elucidate their potential niche breadth. To examine potential phenotypic plasticity and functional trait responses to salinity stress in the invasive cordgrass Spartina densiflora, we collected rhizomes from four invasive populations occurring from California to Vancouver Island, British Columbia on the Pacific Coast of North America. In a glasshouse common …
A Putative Dual Role For Yorkie In Hippo Pathway Signaling, Caroline Hall
A Putative Dual Role For Yorkie In Hippo Pathway Signaling, Caroline Hall
Celebration of Scholarship 2012-2017
The Hippo Pathway inactivates genes involved in organ size and when aberrant, can lead to cancer. To control organ size, the Hippo Pathway inhibits Yorkie (Yki), a transcriptional co-activator that works with Scalloped (Sd), a DNA binding protein. When active, Yki translocates into the nucleus and initiates transcription. Conversely, when inactive, Yki remains in the cytoplasm. However, my work shows that cytoplasmic, inactive Yki interacts with other proteins in the Hippo Pathway by recruiting them to the plasma membrane. Accordingly, this study challenges the notion that cytoplasmic Yki is inactive and instead, may play a dual role in the Hippo …
The Chondrocranium Of Lepidochelys Olivacea And The Taenia Marginalis, Vinh Trinh
The Chondrocranium Of Lepidochelys Olivacea And The Taenia Marginalis, Vinh Trinh
Celebration of Scholarship 2012-2017
This study describes the anatomy of the chondrocranium of Lepidochelys olivacea (Cryptodira, Cheloniidae) through embryonic development, and aims to understand the taenia marginalis. Cleared and double-stained embryos were dissected and observed. The taenia marginalis is present as a thin, ribbon-like process that extends posteriorly from the dorsal margin of the planum supraseptale, and was found to be present as a transient anatomical bridge between the planum supraseptale and the otic capsule in a late Stage 24 specimen. Though present and well-formed for a short period of time, the taenia martinalis is quickly resorbed and is absent in all later specimens …

Among coccoid Cyanobacteria, special reproductive cells have been found: exocytesand baeocytes. These cells can be very different in terms of development. Exocytesare attached to the apical part of the mother cells. Baeocytesdevelop inside the mother cells, forming robust sheaths (Fig.1.A;B). In the phylogenetic sense, representatives of exocytesproduction belong to the CHROOCOCCALES, as opposed to baeocytesproducers which occur in the PLEUROCAPSALES (Fig.2.). In our research we found coccoid cyanobacteria, that produce baeocytesfrom the Mexican Riviera on the Yucatan Peninsula

Lactate Dehydrogenase Is Crucial For Tumor Associated Macrophage Protection Of Multiple Myeloma Cells Against Chemotherapy, Carolyn Stierhoff
Lactate Dehydrogenase Is Crucial For Tumor Associated Macrophage Protection Of Multiple Myeloma Cells Against Chemotherapy, Carolyn Stierhoff
Celebration of Scholarship 2012-2017
Multiple myeloma (MM) is a cancer characterized by an accumulation of malignant plasma cells in the bone marrow. Although chemotherapy is the most effective treatment, the majority of patients experience relapse. The major cause of treatment failure is the development of multidrug resistance. Thus, overcoming drug resistance will greatly improve patient survival. The enzyme lactate dehydrogenase (LDH) plays an important role in anaerobic respiration by converting pyruvate into lactate in the absence or low supply of oxygen. It has been observed that tumor-associated macrophages (TAMs) present in tumor environments can protect MM from chemotherapy treatment. We discovered that an LDH …

Clinical Guidelines In Practice: How Well Are Primary Care Providers Following National Chronic Kidney Disease Recommendations?, Kaitlyn Edbauer
Celebration of Scholarship 2012-2017
Chronic kidney disease (CKD), prevalent in more than 10% of the United States population, is a progressive, degenerative disease affecting the renal function of afflicted individuals. CKD has gained awareness among clinicians due to growing concern about the many complications that arise in patients with CKD. The KDIGO (Kidney Disease; Improving Global Outcomes) 2012 clinical guidelines for the treatment of CKD created uniform measures aimed to improve quality care and effective treatment of the CKD population. This study investigates the extent to which these measures are being implemented and adhered to among providers at the practice level.
Trait Responses Of Invasive Aquatic Macrophyte Congeners: Colonizing Diploid Outperforms Polyploid, Rebecca E. Drenovsky, Brenda J. Grewell, Meghan J. Skaer Thomason, C. J. Futrell, M. Iannucci
Trait Responses Of Invasive Aquatic Macrophyte Congeners: Colonizing Diploid Outperforms Polyploid, Rebecca E. Drenovsky, Brenda J. Grewell, Meghan J. Skaer Thomason, C. J. Futrell, M. Iannucci
Biology
Understanding traits underlying colonization and niche breadth of invasive plants is key to developing sustainable management solutions to curtail invasions at the establishment phase, when efforts are often most effective. The aim of this study was to evaluate how two invasive congeners differing in ploidy respond to high and low resource availability following establishment from asexual fragments. Because polyploids are expected to have wider niche breadths than diploid ancestors, we predicted that a decaploid species would have superior ability to maximize resource uptake and use, and outperform a diploid congener when colonizing environments with contrasting light and nutrient availability.
