TL;DR: The results show that warming in the tropics, although relatively small in magnitude, is likely to have the most deleterious consequences because tropical insects are relatively sensitive to temperature change and are currently living very close to their optimal temperature, so that warming may even enhance their fitness.

TL;DR: It is shown that a highly structured course design, based on daily and weekly practice with problem-solving, data analysis, and other higher-order cognitive skills, improved the performance of all students in a college-level introductory biology class and reduced the achievement gap between disadvantaged and nondisadvantaged students—without increased expenditures.

TL;DR: Students in the new course designs performed better: There were significantly lower failure rates, higher total exam points, and higher scores on an identical midterm, and attendance and course grade were positively correlated.

TL;DR: It is indicated that multiple genetic sources can promote rapid diversification and speciation in response to new ecological opportunity, in agreement with the emerging phylogenomic understanding of the complexity of both ancient and recent species radiations.

TL;DR: The authors found that highly structured course designs, which implement reading quizzes and/or extensive in-class active learning activities and weekly practice exams, can lower failure rates in an introductory biology course for majors, compared with low-structure course designs that are based on lecturing and a few high-risk assessments.
