Intraspecific Floral Color Variation As Perceived By Pollinators And Non-Pollinators: Evidence For Pollinator-Imposed Constraints?, Kellen Cedar Paine

Biology ETDs

Pollinator-mediated selection is expected to constrain floral color variation within plant populations, yet populations with high color variability are common in nature. To explore this, we collected floral reflectance spectra for 34 populations of 14 plant species of New Mexico, USA, and translated them into three different visual spaces. We found evidence that the majority comparisons were indistinguishable to bees, the dominant pollinator group. We also found that floral color variation was significantly greater for two non-pollinating groups, birds and humans. Our results suggest that a portion of human-perceived floral color variation within populations persists because it is invisible to …

Unleashing Endogenous Tnf-Alpha As A Cancer Immunotherapeutic., Steven F Josephs, Thomas E Ichim, Stephen M Prince, Santosh Kesari, Francesco M Marincola, Anton Rolando Escobedo, Amir Jafri

Articles, Abstracts, and Reports

Tumor necrosis factor (TNF)-alpha was originally identified in the 1970s as the serum mediator of innate immunity capable of inducing hemorrhagic necrosis in tumors. Today, a wide spectrum of biological activities have been attributed to this molecule, and clinical translation has mainly occurred not in using it to treat cancer, but rather to inhibit its effects to treat autoimmunity. Clinical trials utilizing systemic TNF-alpha administration have resulted in an unacceptable level of toxicities, which blocked its development. In contrast, localized administration of TNF-alpha in the form of isolated limb perfusion have yielded excellent results in soft tissue sarcomas. Here we …

P-Value Histograms: Inference And Diagnostics, Patrick Breheny, Arnold Stromberg, Joshua Lambert

Statistics Faculty Publications

It is increasingly common for experiments in biology and medicine to involve large numbers of hypothesis tests. A natural graphical method for visualizing these tests is to construct a histogram from the p-values of these tests. In this article, we examine the shapes, both regular and irregular, that these histograms can take on, as well as present simple inferential procedures that help to interpret the shapes in terms of diagnosing potential problems with the experiment. We examine potential causes of these problems in detail, and discuss potential remedies. Throughout, examples of irregular-looking p-value histograms are provided and based …

Identification Of Biologically Essential Nodes Via Determinative Power In Logical Models Of Cellular Processes, Trevor Pentzien, Bhanwar L. Puniya, Tomáš Helikar, Mihaela Teodora Matache

Mathematics Faculty Publications

A variety of biological networks can bemodeled as logical or Boolean networks. However, a simplification of the reality to binary states of the nodes does not ease the difficulty of analyzing the dynamics of large, complex networks, such as signal transduction networks, due to the exponential dependence of the state space on the number of nodes. This paper considers a recently introduced method for finding a fairly small subnetwork, representing a collection of nodes that determine the states of most other nodes with a reasonable level of entropy. The subnetwork contains the most determinative nodes that yield the highest information …

Cellulose-Derived Glycosaminoglycan Mimetic For Use In Cartilage Tissue Engineering Strategies, Roseline Dominic Menezes

Dissertations

Articular cartilage has limited healing and self-repair capability due to the absence of vasculature, lymphatic vessels, and nerves. Damage to articular cartilage becomes irreversible leading to formation of osteoarthritis that could severely degrade a person's quality of life. Approximately, 5-10% of cartilage tissue is made up of glycosaminoglycans (GAG), which sequester growth factors as well as provide structural integrity to the native cartilage tissue. Transforming growth factor-beta3 (TGF-β3) is an important growth factor for inducing chondrogenesis in mesenchymal stem cells (MSCs). Bioavailability of TGF-β3 plays a critical role in cartilage repair both in vitro and in vivo. This study evaluates …

Palynological Investigations Of Agropastoralism And Ecological Change At La 20,000, New Mexico, Anya Gruber

Graduate Masters Theses

How did Spanish colonialism alter the landscape of north-central New Mexico? Agropastoral practices imported by Spanish colonists made indelible impacts on an anthropogenic landscape already shaped by hundreds of years of Pueblo agriculture. However, the precise nature of these changes is poorly understood. This project uses two sets of archaeological pollen data from LA 20,000, a Spanish rancho in New Mexico, to demonstrate how 17th century agriculture and animal husbandry made geographically specific, multifaceted changes to the environment. First, patterns analyzed from a pollen column illuminates fluctuations in plant communities over time, indicating localized ecological shifts. Second, sediments collected from …

A Closed Mouth Gonna Get You Nothin’: How Conflict Is Handled After Diversity And Inclusion Training, Enrico E. Manalo

Graduate Masters Theses

Diversity and Inclusion training is often used in organizations to engage with the increasing demographic diversity in the United States. However, many organizations continue to base their trainings and initiatives on a paradigm which was primarily motivated to prevent litigation, rather than to ensure economic opportunity for all. Over time, such Diversity efforts failed in many documented instances to ensure such opportunities and in fact, created a host of unwanted side-effects, such as employee turnover, job dissatisfaction, and misconceptions regarding the soundness of Diversity and Inclusion efforts.

However, a number of organizations have undertaken Diversity and Inclusion efforts in earnest. …

Investigating The Functions Of Two Transcription Factors In Vascular Development And Wall Biosynthesis In Arabidopsis Thaliana, Qian Du

Doctoral Dissertations

Plant vascular system is important for plant growth and development. There are three different cell types in vascular tissues, xylems, phloems and procambial or cambial. In the presence of cambium, plants continuously generate new vascular tissues. During the differentiation process, xylem fibers develop lignified secondary cell walls which provide abundant resources for biofuel industry. However, the underlying mechanisms of vascular development and secondary cell wall formation are still elusive. Our objectives are to identify new transcription factors function in vascular initiation and biomass deposition in Arabidopsis. In this thesis, we identified two activation-tagging mutants, hva-d with high vascular activity …

The Effects Of Density Gradients On The Distribution And Behavior Of Copepods, Connor Cayson

Theses

Observations of fine-scale behavioral dynamics of zooplankton may shed insight into much larger-scale ecosystem patterns and phenomena. Some zooplankton, such as copepods, are known to aggregate near density gradients; however, it is not clear the extent to which density gradients alone affect copepod distribution and behavior, since these gradients are often associated with phytoplankton layers. In this study, we investigated the behavior of Calanus pacificus in response to salinity gradients through laboratory experiments observed with high-resolution video and analyzed using computational techniques. Image data were collected using two cameras recording continuously for a duration of 30 minutes or more, allowing …
