The Grants’ legendary explorations of the group of 18 bird species known as Darwin’s finches that populate the Galápagos island of Daphne Major — which is in an entirely natural state unaffected by humans — over four decades have produced an array of dazzling insights into evolutionary theory.
“This is one of the only instances I’ve ever heard of where you can have cost-negative carbon sequestration,” said Timothy Treuer, co-lead author of the study and a graduate student in Princeton’s Department of Ecology and Evolutionary Biology.
Researchers identify a common underlying genetic basis for social behavior in dogs and humans. Co-lead authors Bridgett vonHoldt, assistant professor in EEB, and Emily Shuldiner, a 2016 Princeton alumna, worked together to pinpoint the commonalities in the genetic architecture of Williams-Beuren syndrome and canine tameness.
Sims studied the coral reefs of Bermuda and found that nitrogen from polluted groundwater inhibits coral growth, but that healthy fish populations and relatively low levels of phosphate pollution have allowed the reefs to remain stable in spite of pollution coming from the groundwater.
A pair of bald eagles in British Columbia’s Shoal Harbour Migratory Bird Sanctuary snatched up two red-tailed hawk chicks and brought them back to their nest — alive. While one hawklet became a meal, the other was fed by the eagles. “The fact that the eagles are feeding it is actually not surprising,” said Christina Riehl, a biologist at...
Twelve Princeton undergraduates will pursue internships and conduct research internationally this summer as Streicker Fellows.
Earth Day 2017 is shaping up to be one of the most politically charged in a generation.
