Caption: University of Arizona ecologist Henry Adams is pictured with pinyon pine trees inside the 3.4-acre Biosphere 2 dome, where climate was controlled to test the heat effect on drought-stressed trees. "Since much of my work was done in 17 hour shifts, I look unhappy and tired in a lot of photos from Biosphere 2," Adams said.
