hyporheic zone

Climate change is causing some alpine streams to change from always flowing to flowing only part of the time. This is a challenge that the bugs in those streams have not had to face, but the might have a way out: hunkering down in the hyporheic zone, a subsurface component of the stream. By waiting out drought in this new environment, the bugs might be able to come back and resume life as normal when conditions are more favorable.
