Objectives: Adolescents with attention-deficit/hyperactivity disorder are at high risk for sleep difficulties, though sleep problems are widely recognized as a public health concern for adolescents broadly. School climate represents a potentially critical but understudied influence on sleep difficulties, given growing evidence supporting its association with health outcomes. The present study is the first to utilize a multimethod, multi-informant approach, including adolescent-report, parent-report, and actigraphy, to examine associations between school climate and different aspects of sleep functioning among adolescents with and without attention-deficit/hyperactivity disorder.
Methods: Participants included a well-characterized sample of adolescents (45.1% female, 82.6% White) with attention-deficit/hyperactivity disorder (n = 151) and without attention-deficit/hyperactivity disorder (n = 137) between 13 and 15 years old (M = 14.09).
Results: Multigroup path analyses controlling for demographic characteristics, internalizing symptoms, and medication use indicated better-perceived school climate was associated with less adolescent-reported daytime sleepiness and fewer sleep/wake problems, regardless of attention-deficit/hyperactivity disorder status, though stronger associations were found in the non-attention-deficit/hyperactivity disorder group. In contrast, for both adolescents with and without attention-deficit/hyperactivity disorder, school climate was not significantly associated with adolescent- or actigraphy-measured sleep duration, actigraphy-assessed sleep efficiency, or parent-reported sleep quality.
Conclusions: Collectively, findings indicate school climate is associated with specific vs. broad-based aspects of sleep, and that associations may differ based on how sleep is assessed. Findings also contribute to an emerging evidence base supporting the importance of school climate to adolescent sleep quality.

The coordination of floral developmental stages with the environment is important for reproductive success and the optimization of crop yields. The timing of different developmental stages contributes to final yield potential with optimal adaptation enabling development to proceed without being impacted by seasonal weather events, including frosts or end of season drought. Here we characterise the role of FLOWERING LOCUS T 3 (FT3) in hexaploid bread wheat (Triticum aestivum) during the early stages of floral development.

Introduction: The increasing use of biodegradable plastics has led to the inevitable human consumption of biodegradable microplastics (MPs). These MPs can be degraded and absorbed into various organs and tissues via the gastrointestinal tract, with the liver being the primary target for digestion and absorption.
Objectives: This study aimed to investigate the toxic effects and mechanisms of biodegradable MPs on the liver following gastrointestinal degradation.

Human activities contribute to large shifts in the global climate, with far-reaching impacts on ecosystems, societies, and human health. Modern food systems-designed to produce convenience foods that tend to have high inflammatory potential-exacerbate environmental degradation and shape the interwoven challenges of climate, nutrition, and health. Over the past three decades, extreme weather has worsened and poor diets have led to more inflammation-related health problems-two parallel trends that are exposing system-wide weaknesses and harming global health.

Small lakes are common across the Boreal-Arctic zone. Due to shallowness and high shoreline-surface area ratios, they are abundant in aquatic macrophytes. Vegetated littoral zones have been suggested to count as wetlands when quantifying carbon sinks and sources, but the actual magnitude of aquatic vegetation is seldom quantified.

Acid mine drainage (AMD) is a serious environmental problem at legacy and active mine sites around the world. Climate associated drought and rewetting events can increase the severity of AMD impacts through oxidation and release of stored metal(loid)s and acidity from contaminated sediments. The area surrounding Sudbury, Ontario, with its massive mining and smelting complexes, appears especially vulnerable to drought-driven effects.
