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:
"The microbial compositions of hot springs are strongly influenced by temperature and pH. _Acidithiobacillus_ bacteria are found in diverse hot springs, but the genomic features that enable their adaptability are unclear. A recent DNA sequencing study analyzed the genomes of _Acidithiobacillus_ from hot springs in New Zealand and compared them to published non-hot-spring _Acidithiobacillus_ sequences. _Acidithiobacillus_ typically accounted for over 10% of the prokaryote abundance in the springs. Three species, including two novel species (TVZ\\_G2 and TVZ\\_G3), accounted for over 90% of _Acidithiobacillus _and were found in springs with wide-ranging characteristics. A fourth related novel species was also found, although in low abundance. All four species were found at temperatures and pHs above the known limits for _Acidithiobacillus, _likely because they had more GC bases and proline codons in their DNA than other species, increasing their thermostability..."
