Climate change alters the way in which species interact with one another--a reality that applies not just to today or to the future, but also to the past. "We found that, at all time scales, climate change can alter biotic interactions in very complex ways," said paleoecologist Jessica Blois of the University of California, Merced, the study's lead author. "If we don't incorporate this information when we're anticipating future changes, we're missing a big piece of the puzzle."

Researchers study how various sizes, shapes of volcanic ash travel through the atmosphere.

Spurred by increasing levels of atmospheric carbon dioxide, forests over the last two decades have become dramatically more efficient in how they use water. Scientists affiliated with the National Science Foundation's (NSF) Harvard Forest Long-Term Ecological Research (LTER) site report the results in this week's issue of the journal Nature.
