Impacts of Temperature on O2 Consumption of the Pyrenean Brook Newt (\u3ci\u3eCalotriton asper\u3c/i\u3e) from Populations Along an Elevational Gradient
No full textGlobal warming impacts biodiversity worldwide, leading to species\u27 adaptation, migration, or extinction. The population\u27s persistence depends on the maintenance of essential activities, which is notably driven by phenotypic adaptation to local environments. Metabolic rate – that increases with temperature in ectotherms - is a key physiological proxy for the energy available to fuel individuals\u27 activities. Cold-adapted ectotherms can exhibit a higher resting metabolism than warm-adapted ones to maintain functionality at higher elevations or latitudes, known as the metabolic cold-adaptation hypothesis. How climate change will affect metabolism in species inhabiting contrasting climates (cold or warm) is still a debate. Therefore, it is of high interest to assess the pace of metabolic responses to global warming among populations adapted to highly different baseline climatic conditions. Here, we conducted a physiological experiment in the endemic Pyrenean brook newt (Calotriton asper). We measured a proxy of standard metabolic rate (SMR) along a temperature gradient in individuals sampled among 6 populations located from 550 to 2189 m a.s.l. We demonstrated that SMR increased with temperature, but significantly diverged depending on populations\u27 origins. The baseline and the slope of the relationship between SMR and temperature were both higher for high-elevation populations than for low-elevation populations. We discussed the stronger metabolic response observed in high-elevation populations suggesting a drop of performance in essential life activities for these individuals under current climate change. With the increase of metabolism as the climate warms, the metabolic-cold adaptation strategy selected in the past could compromise the sustainability of cold-adapted populations if short-term evolutionary responses do not allow to offset this evolutionary legacy
Can Functional Tests Predict Throwing Velocity or Batting-Exit Velocity in Division III Collegiate Baseball: A Predictive Validity Investigation
Full text linkUnderstanding the relationships between functional performance tests and actual sport performance is important for sport coaches and trainers. The purpose of this study is twofold: (1) Do relationships exist between upper body, lower body or whole-body tests of strength and power with throwing or batting velocity (2) Which variable or group of variables best predict the sport-specific tasks of throwing and batting velocity
\u3cem\u3eThe French Revolution\u3c/em\u3e Now; or, Carlyle’s Eternal Return
Full text linkThis essay utilizes the publication of the first scholarly edition of The French Revolution: A History (1837) as an occasion to reassess this thoroughgoingly radical—and puzzlingly neglected—masterpiece. It explores how Thomas Carlyle\u27s maverick conceptions of sympathy and affect, the relationship of the individual and the collective, and narrative itself underlie the audacious stylistic innovations that characterize this singular text. Moreover, this paper interprets Carlyle\u27s history as a chronicle of inverted utopianism; that is, an apocalyptic manifestation of what is nevertheless a properly utopian longing for heaven on earth. Thus read, The French Revolution offers perspective on our own volatile times as well as a promise—or perhaps a warning—that the insurrectionary struggle for Liberty, Equality, and Fraternity is not over
\u3cem\u3eMedieval Ballads in Miniature\u3c/em\u3e and \u3cem\u3eOur New Gold\u3c/em\u3e: Collaborative Theatre Projects in the Digital Era
No full textThis article discusses two collaborative theatre projects developed virtually due to COVID-19 restrictions during the 2020–2021 academic year. These projects—Medieval Ballads in Miniature: A Shadow of Myself and Our New Gold—highlight the dynamics of theatrical collaboration outside the traditional performing arts setting or classroom and show how these can be truly synergistic and enriching for academic and non-academic audiences
Social Justice in Spanish Golden Age Theatre
No full textThis collection of original new essays focuses on the many ways in which early modern Spanish plays engaged their audiences in a dialogue about abuse, injustice, and inequality. Far from the traditional monolithic view of theatrical works as tools for expanding ideology, these essays each recognize the power of theatre in reflecting on issues related to social justice. The first section of the book focuses on textual analysis, taking into account legal, feminist, and collective bargaining theory. The second section explores issues surrounding theatricality, performativity, and intellectual property laws through an analysis of contemporary adaptations. The final section reflects on social justice from the practitioners\u27 point of view, including actors and directors. Social Justice in Spanish Golden Age Theatre reveals how adaptations of classical theatre portray social justice and how throughout history the writing and staging of comedias has been at the service of a wide range of political agendas.https://digitalcommons.owu.edu/worldlang_books/1000/thumbnail.jp
Impact of Yoga on Youth Anxiety
No full textAnxiety disorders are the most prevalent psychological disorder among children. Over 4 million youths have a serious psychiatric disorder that causes significant impairments. Prevalence data of a representative U.S. sample showed that 50% of adolescents affected by anxiety had their onset before the age of six. Anxiety is associated with mood disorders, suicide attempts, and psychiatric hospitalization. The impact of anxiety on youth is significant which is why there is a push to find effective ways to reduce anxiety. Yoga has been an increasingly popular activity with the youth populations. In 2007, over 1.5 million children were participating in yoga programs in the United States. Yoga is described as mindful and contemplative practice that includes structured activities that “require individuals to exercise volitional control” over their physical and mental activity. Yoga for children often modifies the movements and postures and focuses on mental and emotional awareness and self regulation skills. There have been many studies about the positive effects of yoga on the adult population. However, there is a lack of evidence on the effectiveness of yoga in reducing anxiety in children and adolescents

Thermal Adaptation Revisited: How Conserved are Thermal Traits of Reptiles and Amphibians?
No full textDoes Hyperoxia Restrict Pyrenean Rock Lizards \u3ci\u3eIberolacerta bonnali\u3c/i\u3e to High Elevations?
No full textEctothermic animals living at high elevation often face interacting challenges, including temperature extremes, intense radiation, and hypoxia. While high-elevation specialists have developed strategies to withstand these constraints, the factors preventing downslope migration are not always well understood. As mean temperatures continue to rise and climate patterns become more extreme, such translocation may be a viable conservation strategy for some populations or species, yet the effects of novel conditions, such as relative hyperoxia, have not been well characterised. Our study examines the effect of downslope translocation on ectothermic thermal physiology and performance in Pyrenean rock lizards (Iberolacerta bonnali) from high elevation (2254 m above sea level). Specifically, we tested whether models of organismal performance developed from low-elevation species facing oxygen restriction (e.g., hierarchical mechanisms of thermal limitation hypothesis) can be applied to the opposite scenario, when high-elevation organisms face hyperoxia. Lizards were split into two treatment groups: one group was maintained at a high elevation (2877 m ASL) and the other group was transplanted to low elevation (432 m ASL). In support of hyperoxia representing a constraint, we found that lizards transplanted to the novel oxygen environment of low elevation exhibited decreased thermal preferences and that the thermal performance curve for sprint speed shifted, resulting in lower performance at high body temperatures. While the effects of hypoxia on thermal physiology are well-explored, few studies have examined the effects of hyperoxia in an ecological context. Our study suggests that high-elevation specialists may be hindered in such novel oxygen environments and thus constrained in their capacity for downslope migration
