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:
"Life, in all its forms, is a constant balance of energy and matter. A look at any food web reveals how organisms are tightly connected to each other and their environment. On the smallest and most fundamental scale, the process is cyclical. Atoms representing vital minerals flow in a never-ending circuit from one sink to the next. Understanding this flow helps scientists answer questions about how organisms transform food into energy and body mass for growth and survival. But while these strategies tend to vary with species, life stage, and sex, studies often treat members of a population as being, for all intents and purposes, the same. Researchers from Jagiellonian University in Poland are taking a different approach. By tracking the assimilation, excretion, and allocation of the individual minerals found in pollen, they’re beginning to understand how the diet of the red mason bee contributes to its growth and survival and how the nutritional budget differs with life stage and sex..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.
