The course includes survey and special topics designed for graduate students in the brain and cognitive sciences. It emphasizes ethological studies of natural behavior patterns and their analysis in laboratory work, with contributions from field biology (mammology, primatology), sociobiology, and comparative psychology. It stresses mammalian behavior but also includes major contributions from studies of other vertebrates and of invertebrates. It covers some applications of animal-behavior knowledge to neuropsychology and behavioral pharmacology.

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.

Submitted as part of the California Learning Resource Network (CLRN) Phase 3 Digital Textbook Initiative (CA DTI3), CK-12 Foundation’s high school Biology FlexBook covers cell biology, genetics, evolution, ecology, botany, zoology, and physiology. This digital textbook was reviewed for its alignment with California content standards.

An integrated course stressing the principles of biology. Life processes are examined primarily at the organismal and population levels. Intended for students majoring in biology or for non-majors who wish to take advanced biology courses.

This activity is an interactive game that helps students learn that vertebrates are classified into five groups and that each group has common characteristics that distinguish the animal group from other respective groups.

Join Philip Hastings, curator of the Marine Vertebrate Collection at Scripps and learn how research on fishes of the Gulf of California and Southern California is essential for guiding conservation efforts aimed at protecting marine fisheries and ecosystems. (56 minutes)

This virtual tour of the Sternberg Museum of Natural History covers a broad range of Cretaceous fauna with emphasis on marine life of the Western Interior Seaway. Topics include large marine fish (Xiphactinus), Inoceramid clams, mosasaurs, plesiosaurs, ichthyosaurs, large turtles (Protostega), flightless toothed birds, dinosaurs (including Tyrannosaurus rex), flying reptiles (Pteranodons) and the Western Interior Seaway.

This lesson helps grade 3 students understand the difference between Vertebrates and Invertebrates.
