Specimens from the Museum of Vertebrate Zoology have helped IB scientists discover that the genes that determine the size of your front teeth are different from those that determine the size of your back teeth—a step towards figuring out how nature makes teeth and how we might be able to use this in the dentist's office.
Sky lupines (Lupinus nanus) are a common spring resident of California annual grasslands. Lupines add nitrogen to the soil through their mutually beneficial symbiosis with root-nodulating rhizobium bacteria.
The Valley Life Sciences Building (VLSB) was initially constructed in 1930 and was renovated approximately 60 years later as one of four building projects (Life Sciences Building, Life Sciences Addition, Genetics & Plant Biology Building, North West Animal Facility) undertaken to revitalize the biological sciences on the UC Berkeley Campus.
This salamander (Ensatina eschscholtzii xanthoptica), with orange skin and bright yellow eyes, is a mimic of the Western Newt (Taricha sp.), a poisonous species that lives in the same habitat with Ensatina around the Bay Area.

Rana margaretae is a part of an amphibian community formed by six species living in or around the same stream. The microhabitats vary between these species, and the available resources is partitioned and consumed differently. Tadpoles of the different species forage and graze differently.

Professor Robert Dudley has published a new book (The Drunken Monkey: Why We Drink and Abuse Alcohol; University of California Press, 2014) that assesses the evolutionary origins of attraction to alcohol. Read More
The Department of Integrative Biology (IB) offers Undergradate and Graduate academic programs as well as Faculty Research that focuses on the integration of structure and function that influences the biology, ecology, and evolution of organisms. It investigates integration at all levels of organization from molecules to the biosphere, and in all branches of the tree of life: plants, animals, fungi, and microbes.
