Congratulations to IB Professor Rasmus Nielsen, who has been elected to the National Academy of Sciences.
Many of the birds that awaken us each morning learn their melodious songs the same way that humans learn a dialect — from parents and neighbors.
While frog and salamander declines worldwide have made scientists outspoken about the need to preserve amphibian genetic diversity, two University of California, Berkeley, biologists emphasize another important reason for conserving these animals: their poisons.
A new study by biologists from the University of California, Berkeley, and Missouri State University in Springfield, however, documents songs in East African sunbirds that have remained nearly unchanged for more than 500,000 years, and perhaps for as long as 1 million years, making the songs nearly indistinguishable from those of relatives from which they’ve long been separated.
The University of California, Berkeley is holding its second virtual Graduate Diversity Admissions Fair October 18-22 to help prospective professional, master's, and doctoral students learn more about UC Berkeley overall, our application process, and departments in your area of interest.
Graduate Diversity Admissions Fair
Dates: Monday, Oct. 18 through Friday, Oct. 22
IB Grad Program Info Session: Oct 19, 2-3pm PST
University of California, Berkeley, doctoral candidate Lawrence Wang, leader of the squirrel documentation project and his team refined efforts to produce the high quality cover images of the August 2021 issue of Science magazine. Their efforts produced some of the best high quality motion shots of fox squirrels showing off their stuff as they leap through the air.
Biologists like Robert Full at the University of California, Berkeley, have shown over the last few decades how animals like geckos, cockroaches and squirrels physically move and how their bodies and limbs help them in sticky situations — all of which have been applied to making more agile robots. But now they are tackling a harder problem: How do animals decide whether or not to take a leap? How do they assess their biomechanical abilities to know whether they can stick the landing?
A new book entitled “What, if Anything, are Species?” by IB Professor Brent Mishler explores this controversial topic in detail, based on 40 years of investigation. He concludes that species are nothing special; entities currently given that rank are simply clades like taxa at all other levels on the tree of life, smaller or larger than the traditional species level. He goes into the advantages of fully rankless classification, and of a multi-level approach to ecology and evolution.
