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.

By the end of this section, you will be able to:Discuss the biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfurExplain how human activities have impacted these cycles and the potential consequences for Earth

Students are presented with a guide to rain garden construction in an activity that culminates the unit and pulls together what they have learned and prepared in materials during the three previous associated activities. They learn about the four vertical zones that make up a typical rain garden with the purpose to cultivate natural infiltration of stormwater. Student groups create personal rain gardens planted with native species that can be installed on the school campus, within the surrounding community, or at students' homes to provide a green infrastructure and low-impact development technology solution for areas with poor drainage that often flood during storm events.

"Microorganisms are critical drivers of biogeochemical cycles and are the most abundant organisms in frigid regions. Identifying the genomic traits of cold-loving microbes may help explain their physiology and adaptation, but recognizing which genomic traits are important for environmental adaptation is challenging. A new study compared the genomes of Arthrobacter bacteria isolated from the Tibetan Plateau with published genomes of related bacteria and defined a new group of Arthrobacter that live in polar and alpine environments. In the laboratory, the bacteria in this group grew comparatively rapidly at 0 °C. Compared to bacteria from warmer environments, the polar/alpine bacteria had different genomic and amino acid compositions, and their predicted proteins had different stability levels and functions..."

"Isoprene is the most abundantly produced biogenic volatile organic compound (BVOC) on earth.,with annual global emissions rivaling those of methane. Unfortunately, surprisingly little is known about how isoprene is degraded in the environment. A recent study reveals a new set of bacteria that can metabolize isoprene. Researchers used DNA isotope probing to study microbes that degrade isoprene derived from oil palm trees. Among the new genera they discovered were Novosphingobium, Pelomonas, Rhodoblastus, Sphingomonas and Zoogloea. Metagenomic analysis further demonstrated that oil palm soil harboured more and more-diverse isoprene-degrading bacteria than leaves. That finding suggests that oil palm soils could be a bigger sink for isoprene than previously thought. Understanding the distribution and identity of isoprene degraders in the environment is crucial. to determine the extent to which microbes mitigate the effects of this abundant but neglected climate-active gas..."
