How strong are the links in food webs? An experiment at Washington University in St. Louis demonstrates that they’re strong enough for a disturbance to propagate across four trophic levels and two ecosystems. The experiment demonstrates that invasive species such as purple loosestrife could have broad effects on surrounding plant and animal communities, many of them cryptic.
Sixteen St. Louis youth will be in Forest Park on June 13 tracking box turtles, fitted with telemetry devices — all to help with a project aimed at studying box turtle movements and their health. The 12- and 13-year-olds are participating in a pilot study designed by scientists from the Saint Louis Zoo and Washington University in St. Louis to document box turtle movements and their health status in urban and rural areas in and around St. Louis.
The Association for the Advancement of Sustainability in Higher Education will name Washington University in St. Louis as the winner of its “Best Lessons Learned Case Study Award” on Tuesday, Oct. 11, during the AASHE 2011 Conference in Pittsburgh. The award, for the case study, “Getting to Net-Zero: Lessons Learned from a Living Building Challenge,” which outlined “the mistakes, corrections, and lessons learned that ultimately led to successful certification” of WUSTL’s Living Learning Center at Tyson Research Center as one of the first net zero energy “living buildings.”
The new Living Learning Center at Tyson Research Center was designed to be one of the greenest buildings in North America. Jonathan Chase, associate professor of biology in the Department of Biology and Environmental Studies in Arts & Sciences and Tyson’s director; and Daniel Hellmuth, principal and co-founder of Hellmuth & Bicknese Architects, L.L.C., will deliver a talk about the Center and its challenges for the Assembly Series at 5 p.m. Thursday, September 24 in Wilson Hall Room 214. The program is free and open to the public.
