Desert mosses use quartz rocks as sun shades

A graduate student at the University of California, Berkeley, found that some mosses in the California desert seek protection from the relentless sun and heat by sheltering under translucent quartz pebbles, essentially using the rocks as sunshades.

The soil under these rocks retains more moisture than exposed desert soil, said Jenna Ekwealor, while enough light leaks through the milky quartz to allow the tiny mosses to remain green with chlorophyll. Mosses actually prefer dim light, making these conditions ideal for growth.

 

Congratulations to Britt Koskella on your Promotion to Associate Professor

Professor Koskella is an evolutionary biologist seeking to understand how interactions among species generate and maintain much of the diversity you see on earth. She is interested in how species interactions influence genetic diversity within populations, diversity between populations, and species diversity at the community level. By combining evolutionary theory on coevolution, population dynamics, and infection genetics, she directly tests the underlying assumptions and predicted outcomes of host-pathogen and microbial interactions through the

Berkeley Changemaker Technology Innovation Grant awardees announced

The Department of Integrative Biology is one of the winners of the first-ever Berkeley Changemaker Technology Innovation Grants. Launched by the office of UC Berkeley Chief Technology Officer (CTO) Bill Allison in the office of Chief Information Officer Larry Conrad, the winning projects, announced today (Thursday, June 25), will share $400,000 in general funds that were earmarked by Conrad in the 2019-2020 school year for information technology (IT

In Memoriam: Stephen Glickman, father of world’s only captive hyena colony

Stephen Glickman, a pioneer in behavioral endocrinology and founder of the world’s first colony of captive spotted hyenas — he raised generations of them in a UC Berkeley research facility — died at his home in Berkeley on May 22 from pancreatic cancer. He was 87.

A professor emeritus of psychology and of integrative biology, whose lifelong bond with animals began during his boyhood near the Bronx Zoo in New York, Glickman joined the UC Berkeley faculty in 1968.

Congratulations to UCMP's Director of Education and Outreach, Dr. Lisa White the newly appointed Chair of the AGU s (American Geophysical Union) Diversity and Inclusion Advisory Committee.

Dr. White joined the UCMP in July 2012 as Director of Education and Outreach. She comes to the UCMP after a 22-year history at San Francisco State University where she held positions of Professor of Geosciences and Associate Dean of the College of Science and Engineering.

Congratulations to Caroline Williams on receiving tenure and her promotion to Associate Professor of Integrative Biology.

Professor Williams research combines field-based natural history and experiments with laboratory-based biochemistry and physiology. She studies how insects and other ectotherms respond to variable environments, using the information to predict how insect populations will change as a result of climate change. Much of her research has focused on winter climate change, and at present she is working on how changing snow cover will impact the physiology, ecology, and evolution of montane beetles.
