Nature highlights research findings from Irwin Lab

Prof. Becky Irwin, Dr. Leif Richardson and other researchers in the Irwin Lab, have found that some compounds in floral nector reduce parasite loads in bees 60%-80%.  While the reduction in parasite load did not increase survival rates, these compounds could confer a benefit to bee colonies by reducing the spread of parasites.  These findings were highlighted in the February 26, 2015 issue of Nature.

EEB Prof. Dominy uses Art to Construct Ecological History of Egypt

Professor Nate Dominy and his collaborators used art and other resources such as census data to construct and ecological history of Egypt.  Their findings have been published in a paper "Collapse of an ecological network in Ancient Egypt" in the Proceedings of the National Academy of Sciences.

His work was featured in Dartmouth Now.  Please click here for a link to the article.
