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:
"A warming climate means big changes for polar wildlife, including the polar regions’ smallest residents. Unfortunately, we have a limited understanding of how polar microbiota adapt to their environments and lack functional studies linking genetics to metabolic traits needed for adaptation. A recent study evaluated microbiota in 60 seawater samples collected from several Arctic and Antarctic regions as well as data from the Tara Oceans project. Using metagenomic sequencing, researchers identified the locally enriched strains in each polar region, which differed from those in temperate locations. The results revealed that these microbes differed in the metabolic pathways needed to adapt to their unique environments. Interestingly, antibiotic resistance genes were enriched in the Arctic, while DNA recombination functions were enriched in the Antarctic..."
