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 koala is an iconic Australian species. Unfortunately, some wild populations are at risk of extinction. Captive breeding programs aiming to manage endangered populations face high mortality rates of pouch-dwelling koala young. Recently, researchers investigated infant koala mortality rates associated with bacterial infection by analyzing the microbiome of koala pouches. Gene sequencing showed that the pouch microbiomes of successfully bred female koalas were dominated by Muribaculaceae bacteria early in lactation, while mother koalas who lost their young had Enterobacteriaceae-dominated pouch microbiomes. The bacterial species associated with poor reproductive outcomes were shown to be resistant to antibiotics commonly administered to captive koalas. This work could help reduce mortality rates of infant koalas in captive breeding programs, assess medication regimens used to treat captive koalas, and support general studies of at-risk wild koala populations..."
