A Review of the Physiological Mechanisms in Stenocara gracilipes, Callipepla gambelii, Dipodomys merriami, and Dipsosaurus dorsalis Permitting Survival During Water Deprivation and Salt Imbalance in the Desert Environment.
No full textWater availability is limited in a desert ecosystem and many organisms have adapted unique mechanisms to maintain salt and water balance during periods of dehydration and rehydration. The darkling beetle (Stenocara gracilipes) and the Gambel’s quail (Callipepla gambelii) both employ metabolic changes, where the darkling beetle will oxidize fat to produce metabolic water1. The Gambel’s quail has a field metabolic rate 60% lower than expected for a bird with similar mass and they also regulate their globular filtration rate to limit water loss through urine3, 4. The kangaroo rat (Dipodomys merriami) and the desert iguana (Dipsosaurus dorsalis) both rely on food as their main water intake and the kangaroo rat has very efficient kidneys to retain water and excrete excess salts, while also having a lower water economy index than other mammals of similar size, indicating that they use water more efficiently7, 8. The desert iguana will primarily excrete excess potassium obtained from their diet through their nasal fluids to maintain ion balance during a rehydration period9. This review showed that a variety of mechanisms have evolved in desert organisms to maintain salt and water balance during drought and rehydration
Nature Quest Journal
Get PDFThrough an assignment titled, “A Campus Nature Quest or Neighborhood Nature Challenge,” Professor Emily Baird encourages students in her first-year college writing course to engage in sensory explorations of urban-area natural spaces. This collection includes a discussion of the project goals, the assignment guidelines, and sample student journal entries. Working through this project, students develop reflective abilities, descriptive writing skills, and confident voices for expressing unique observations about the world around them
The Evolution of Consent-Based Performance: A Literature Review
Get PDFIn lieu of an abstract, here is an excerpt:
...it is important to recognize the evolution of this field and the ways in which documentation around this field has itself created certain power imbalances. [...] Many of those whose work has gone unnamed are artists of color, women, disabled individuals, trans and nonbinary individuals whose own experiences of disempowerment in society and in the performance industry forced them to forge practices to protect themselves. These people are the pioneers of consent-based practice. As an intimacy specialist, I recognize that I may never know the names of many who forged the early path for this field, and I may never know the origin of the foundation upon which my practice continues to build. As a scholar, I want to ensure that our evolution moving forward is documented, and I want to understand whose work I should be crediting as I continue forming my own artistic consent-based praxis as an intimacy choreographer, as an educator, and as a theatre maker. I invite other artists and scholars to add to this literature review, and to document the as-of-yet unpublished history of consent-based practices used in performance, and those who created them
A Computer-Based Approach to Solving the Diophantine Equation
Get PDFAssisted by Octave and by a website where one can find the order of a modulo m (here a and m are relatively prime natural numbers), I found a proof for showing that the diophantine equation has only the solution (x,y) = (3,5) in positive integers
Engaging Millennial Students through Community-Engaged Experiential Learning
No full textMillennial students and workers are high-achieving, have a strong desire for ongoing personal and professional development, and tend to be invested in making a sustainable impact on society and in the communities in which they live and work. One avenue to engage these students is community-engaged experiential learning (or service learning). While service learning is not new, this “civically-engaged” pedagogy has increased in popularity and usage. It provides meaningful community-service opportunities that simultaneously teach civic responsibility and encourage life-long civic engagement, while also providing significant real-life, hands-on learning of important skills and vital social understanding. This quantitative study examines the connections between students’ motivations for enrolling in service-learning courses and their perceived likelihood for course and program completion. It also connects student motivations for enrolling in service-learning courses to the literature on millennial students and preparing students for the future workforce. Findings not only identify gains in service-learning motivations overall, but also specific volunteerism motivations that contribute to students’ expressions of intent for course and program completion. The findings also demonstrate that study participants exhibited typical characteristics associated with the millennial generation and that these are strengthened through service-learning participatio
