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:
"Plants form a close bond with a vast range of microorganisms. In fact, this microbiome could be viewed as an extended phenotype of the plant genome enhancing plants’ ability to cope with environmental stress. To understand this connection, researchers recently examined the microbiome of the model legume Medicago truncatula. They found that bacterial diversity decreased between external and internal plant compartments and that microbiome composition was shaped by strong interactions between compartment type, soil, and plant genotype with the microbial composition of external compartments driven by soil origin and the microbial composition of internal compartments driven by host genetics. All compartments were dominated by Ensifer, the nitrogen-fixing bacteria that form root nodule symbiosis with M. truncatula..."
