Developmental And Molecular Changes Underlying The Vernalization-Induced Transition To Flowering In Aquilegia Coerulea (James), Bharti Sharma, Timothy A. Batz, Rakesh Kaundal, Elena M. Kramer, Uriah R. Sanders, Valerie J. Mellano, Naveen Duhan, Rousselene B. Larson

Center for Integrated Biosystems Publications

Reproductive success in plants is dependent on many factors but the precise timing of flowering is certainly among the most crucial. Perennial plants often have a vernalization or over-wintering requirement in order to successfully flower in the spring. The shoot apical meristem undergoes drastic developmental and molecular changes as it transitions into inflorescence meristem (IM) identity, which then gives rise to floral meristems (FMs). In this study, we have examined the developmental and gene expression changes underlying the transition from the vegetative to reproductive phases in the basal eudicot Aquilegia coerulea, which has evolved a vernalization response independently relative …

Polemic And Literature Surrounding The French Wars Of Religion, Jeff Kendrick, Katherine S. Maynard

Studies in Medieval and Early Modern Culture

Polemic and Literature Surrounding the French Wars of Religion demonstrates that literature and polemic interacted constantly in sixteenth-century France, constructing ideological frameworks that defined the various groups to which individuals belonged and through which they defined their identities. Contributions explore both literary texts and more intentionally polemical texts that fall outside of the traditional literary genres. Engaging the continuous casting and recasting of opposing worldviews, this collection of essays examines literature's use of polemic and polemic's use of literature as seminal intellectual developments stemming from the religious and social turmoil that characterized this period in France.

Sciatic Nerve Cut And Repair Using Fibrin Glue In Adult Mice, Erica T. Akhter, Travis M. Rotterman, Arthur W. English, Francisco J. Alvarez

Neuroscience, Cell Biology & Physiology Faculty Publications

Peripheral nerve injury (PNI) is an excellent model for studying neural responses to injury and elucidating the mechanisms that can facilitate axon regeneration. As such, several animal models have been employed to study regenerative mechanisms after PNI, including Aplysia, zebrafish, rabbits, cats and rodents. This protocol describes how to perform a sciatic nerve injury and repair in mice, one of the most frequently used models to study mechanisms that facilitate recovery after PNI, and that takes advantage of the availability of many genetic models. In this protocol, we describe a method for using fibrin glue to secure the proximal …

Fgf-Signaling Is Compartmentalized Within The Mesenchyme And Controls Proliferation During Salamander Limb Development, Sruthi Purushothaman, Ahmed Elewa, Ashley W. Seifert

Biology Faculty Publications

Although decades of studies have produced a generalized model for tetrapod limb development, urodeles deviate from anurans and amniotes in at least two key respects: their limbs exhibit preaxial skeletal differentiation and do not develop an apical ectodermal ridge (AER). Here, we investigated how Sonic hedgehog (Shh) and Fibroblast growth factor (Fgf) signaling regulate limb development in the axolotl. We found that Shh-expressing cells contributed to the most posterior digit, and that inhibiting Shh-signaling inhibited Fgf8 expression, anteroposterior patterning, and distal cell proliferation. In addition to lack of a morphological AER, we found that salamander …

Precipitation Mediates Sap Flux Sensitivity To Evaporative Demand In The Neotropics, Charlotte Grossiord, Bradley O. Christoffersen, Aura M. Alonso-Rodríguez, Kristina Anderson-Teixeira, Heidi Asbjornsen, Luiza Maria T. Aparecido, Z. Carter Berry, Christopher Baraloto, Damien Bonal, Isaac Borrego

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Transpiration in humid tropical forests modulates the global water cycle and is a key driver of climate regulation. Yet, our understanding of how tropical trees regulate sap flux in response to climate variability remains elusive. With a progressively warming climate, atmospheric evaporative demand [i.e., vapor pressure deficit (VPD)] will be increasingly important for plant functioning, becoming the major control of plant water use in the twenty-first century. Using measurements in 34 tree species at seven sites across a precipitation gradient in the neotropics, we determined how the maximum sap flux velocity (vmax) and the VPD threshold at which …

Insect Hybridization And Climate Change, Erica Larson, R. M. Tinghitella, Scott A. Taylor

Biological Sciences: Faculty Scholarship

Contemporary global change is altering ecosystems at an unprecedented pace and scale. This critical period is a crisis for biodiversity, but the perturbations caused by global environmental change also offer new opportunities to study the evolution of species boundaries—their persistence, formation, or collapse—over rapid evolutionary timescales. Increasing temperature means and fluctuations have the potential to alter gene flow between species through changes in species distributions, interactions, life history, and temperature-dependent behavior. This is particularly true for insects, whose geographic ranges, behaviors, and life history traits are temperature dependent. Here, we review the potential for climate change to influence gene flow …

School of Biological Sciences: Faculty Publications

Large mammals are at high risk of extinction globally. To understand the consequences of their demise for community assembly, we tracked community structure through the end- Pleistocene megafaunal extinction in North America.We decomposed the effects of biotic and abiotic factors by analyzing co-occurrence within the mutual ranges of species pairs. Although shifting climate drove an increase in niche overlap, co-occurrence decreased, signaling shifts in biotic interactions. Furthermore, the effect of abiotic factors on cooccurrence remained constant over time while the effect of biotic factors decreased. Biotic factors apparently played a key role in continental-scale community assembly before the extinctions. Specifically, …

The Indian Child Welfare Act: A Brief Overview To Contextualize Current Controversies., Frank E. E. Vandervort

Articles

Congress passed and the president signed the Indian Child Welfare Act (ICWA) into federal law in 1978. Because the Constitution grants to Congress the authority to make law regarding Indian tribes, ICWA’s provisions are mandatory, unlike other federal child welfare legislation such as the Child Abuse Prevention and Treatment Act, which are voluntary. State authorities handling any case involving an “Indian child” must comply with ICWA.

Bayesmetab: Treatment Of Missing Values In Metabolomic Studies Using A Bayesian Modeling Approach, Jasmit Shah, Guy N. Brock, Jeremy Gaskins

Internal Medicine, East Africa

Background: With the rise of metabolomics, the development of methods to address analytical challenges in the analysis of metabolomics data is of great importance. Missing values (MVs) are pervasive, yet the treatment of MVs can have a substantial impact on downstream statistical analyses. The MVs problem in metabolomics is quite challenging and can arise because the metabolite is not biologically present in the sample, or is present in the sample but at a concentration below the lower limit of detection (LOD), or is present in the sample but undetected due to technical issues related to sample pre-processing steps. The …

Syndemics: Considerations For Interdisciplinary Research, Rosalynn A. Vega

Anthropology Faculty Publications

In this short piece, I explore how medical anthropology could be deployed through interdisciplinary collaborations in a way that is both theoretically rich and poised to positively impact health outcomes. In particular, I consider how research agendas focused on improving health care outcomes reveal certain limitations and underlying assumptions within the discipline. What types of methodological shifts might occur if we interrogate those limitations and assumptions? What are some alternatives? To answer these questions, I turn to the concept of “syndemics” as one example of how a human rights approach can transform the way we do anthropology for the betterment …

Bulletin of Chinese Academy of Sciences (Chinese Version)

The red soil hilly areas in South China were prone to soil erosion due to their poor soil viscosity, poor water permeability, and inadequate seasonal rainfall distribution. Inappropriate tillage measures aggravated soil erosion, decreased soil fertility, and therefore restricted the sustainable development of local agriculture. Since the Taoyuan Agro-ecosystem Research Station, Chinese Academy of Sciences (CAS) was established in 1979, researchers have systematically upgraded management of regional agricultural ecosystem, increased the overall agricultural benefits, and established a technical system and an optimized mode of the comprehensive development of regional agriculture in the station. The demonstration and promotion will provide important …

Biocompatibility Or Toxicology? Oxidative Stress As A Focal Point Of Nanomaterial Design, Thomas Dziubla

Amgen Seminar Series in Chemical Engineering

Of the weapons employed by the body’s defense mechanisms, oxidative stress appears to be the most ubiquitous, non-specific, and damaging. When oxidative mechanisms have been induced (e.g., the leukocyte respiratory burst), it can result in a degenerative cycle of chronic inflammation and cell death, which further stimulates the release of more harsh oxidants. However, under mild conditions, this oxidative stress stimulates tissue regeneration and cellular upregulation of protective mechanisms (e.g., ischemic preconditioning), improving the overall viability and prognosis of tissue health. A delicate balance of pro-oxidant and antioxidant mechanisms constitutively exist to ensure that only the beneficial effects are observed. …
