Todd Dawson focuses on how plants from different ecosystems respond ecologically and physiologically to climatic changes. Using field and greenhouse investigations, analysis of isotope composition of tree-ring cellulose and modeling they'll provide the science needed to guide solution-based management and policy decisions.
This tarantula species, a pink-toe tarantula (Avicularia avicularia) in Kourou, French Guiana, is common throughout northern South America, frequently found in dwellings. The coloration reverses around 4-5 years for juvenile specimens: pink bodies with dark-colored feet.
Like octopus and cuttlefish, cephalopods are masters of camouflage quickly changing color, texture and shape to match their environment. Here, a small octopus from Moorea morphs from a form that conceals it amongst corals to a smoother, lighter version as it jets away over white sand.
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.
Jeff Benca's computer rendering of the long-extinct lycopod, Leclercqia scolopendra, and accompanying article has been chosen as the cover of March’s centennial issue of the American Journal of Botany. Bencas is a graduate student in Assistant Professor Cynthia Looy's Lab. Read More
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.
