In Memoriam: Roberta Park

Last week, the campus community lost an esteemed colleague as IB Professor Emerita Roberta “Robbie” Park passed away peacefully at the age of 87. Roberta had been an invaluable member of the Physical Education program for more than sixty years, from her time as an undergraduate to her service as a faculty member and department chair of the Department of Physical Education (later Human Dynamics, which merged with Integrative Biology in 1997).

As climate and land-use change accelerate, so must efforts to preserve state’s plants

“We just have a decade or two given the rapid pace of climate and land-use change,” said Brent Mishler, a UC Berkeley professor of integrative biology and director of the University and Jepson Herbaria. “Our opportunities, even 10 years down the line, are way more limited compared to what they are now.

The tiny black dots on the soggy leaf that Emily King plucked out of Mount Diablo Creek the other day did not look very threatening, but the UC Berkeley biologist knows well how looks can be deceiving.

Fertilizer destroys plant microbiome’s ability to protect against disease

New research coming out of Assistant Professor Britt Koskella's lab found that spraying tomatoes with microbes from healthy tomatoes protected them from disease-causing bacteria, but that fertilizing the tomatoes beforehand negated the protection, leading to an increase in the population of pathogenic microbes on the plants’ leaves.
