|February 2013: BACE exhibit featured as part of NSF's installation at the 2013 AAAS annual meeting in Boston. Camilla, NASA's space chicken, came by and helped us measure soil respiration. Our "moving billboard" video from the exhibit can be seen here, or at the bottom of this page. Also at the bottom of this page is a Prezi presentation featured on a touch-screen display at our AAAS installation.
January 2013: Babson Magazine highlights Vikki Rodgers' research at the BACE.
Summer 2012: New DOE-funded research on soil carbon begins; this is a collaboration between Purdue and Indiana University (Rich Phillips).
December 2011: The BACE is mentioned in a New Scientist story about discrepancies in the temperature sensitivity of plant phenological events as measured in experiments vs. observations.
October 2011: The BACE is featured in a Boston University story about phenological work done by students in Richard Primack's lab. See story and video.
June 2011: Story and press release discuss new publication on the effects of warming and drought on the chemistry of dead leaves, and possible consequences for ecosystems.
The first meeting of all BACE researchers was held on July 16-17, 2009 in Waltham. See the picture below.
On November 19, 2007 the Daily News Tribune covered the BACE in "Professor is plotting the path of global warming."
On July 10, 2007 the BACE was featured on the 5 o'clock news on WCVB-TV Boston (Channel 5; ABC). You can read or view the story here.

On April 26, 2007 the BACE was featured on the 6 o'clock news on WBZ-TV Boston (Channel 4; CBS), as one installment of their "Project Mass.: Global Warming" series. You can read or view the story here.
On Earth Day 2007 the BACE opened its "Climate Change Classroom" with displays on the topic of climate change. This area is open to the public.
Part of the BACE public exhibit was displayed at the 2007 New England Spring Flower Show at the Bayside Expo Center, where it won a Silver Medal from the Massachusetts Horticultural Society.
You can view many of the displays and obtain more information here.
|What is the BACE?|
The Boston-Area Climate Experiment (BACE) is designed to characterize ecosystem responses to climate change over a response surface, as opposed to testing responses to single step increases. Will the processes and properties of communities and ecosystems respond linearly to changes in temperature, or are there important threshold temperatures that could be reached? To what extent does an ecosystem's response to warming depend on precipitation patterns? The BACE will test these questions experimentally, in a New England old-field ecosystem. Researchers will measure responses of several variables, including growth of wildflowers, grasses, and tree seedlings.
The BACE is coordinated by the Dukes lab at Purdue University and the University of Massachusetts Boston. For more information, contact Jeff Dukes by email (dukes (at) stanfordalumni.org).
Collaborating laboratories include those of: Carol Adair (University of Vermont), Richard Conant (Colorado State University), Michael Daley (Lasell College), Rich Phillips (Indiana University), Richard Primack (Boston University), Eldor Paul (CSU), Vikki Rodgers (Babson College), Nishanth Tharayil (Clemson), Matthew Wallenstein (CSU), and Baoshan Xing (University of Massachusetts Amherst).
|Volunteering at BACE|
We are always looking for volunteers who would be interested in helping us out at our field site in Waltham, Massachusetts. Vounteers can expect to learn more about climate change and old-field ecosystems, as well as the science of ecology. If you're a high school student, college student, recent graduate, or community member and you're interested in getting involved, please email Jeff Dukes at dukes (at) stanfordalumni.org.
