Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Deep-sea hydrothermal vents are extreme environments that typically form along mid-ocean ridges. Although hundreds of vent systems have been identified, those south of 14°S on the Mid-Atlantic Ridge remain relatively unexplored. To learn more, a recent study investigated the microbes inhabiting the newly discovered Deyin-1 vent in this area. Analysis of 219 metagenome-assembled genomes (MAGs) revealed a highly diverse and variable community. Most of the dominant microbes appeared capable of using reduced sulfur and hydrogen as primary energy sources, and many of the microbes seemed to use multiple energy pathways, indicating adaptability to fluctuating conditions. Multiple types of bacteria were also predicted to participate in the same metabolic pathways, suggesting functional redundancy within the community. Furthermore, the genome sequences suggested that a large proportion of microbes could both make their own food and consume other organisms..."
