Symbiosis means "living together", i.e. when two organisms live in close association to benefit each other. For instance, soil bacteria called rhizobia, like Bradyrhizobium diazoefficiens, can enter into symbiosis with leguminous plants, like soybean.

The Bioblitz@Oxy is a citizen science event to document the biodiversity of аIJʿª½±. During this one day event, we will identify as many species as possible on the аIJʿª½± campus. These data will provide baseline knowledge about local biodiversity so we can measure how these species respond to future environmental changes.

We love to study the hidden world of microbes and are particularly excited to investigate microbes directly in their natural environment. My team is interested in many aspects of the nitrogen cycle. Bioavailable nitrogen is essential for all organisms and is the main limiting nutrient for life on our planet.

Chaparral shrub species of California are known for their ability to survive several environmental stresses, such as recurrent summer drought, periodic wildfire, and winter freezing. For example, many species can re-sprout from the ground after fire, and fire stimulates seed germination for other species.

Two biology students have been awarded Science Scholars Fellowships!

Please join us in congratulating Chelsea Blankenchip, a Fletcher-Jones Scholar mentored by Shana Goffredi, and Catherine Conlon, a Norris Scholar mentored by Roberta Pollock!

Biologists have long known that the activity of proteins inside of cells directs the expression of genes. What we generally lack is a quantitative understanding of these regulatory interactions. For example, how does the amount of a regulatory protein determine the nature and extent of regulatory interactions? In this talk, Dr.
