Scientists used artificial stream channels to study the effects of drought on aquatic insects (IMAGE)

University of California, Berkeley, researchers used a network of artificial stream channels to mimic the behavior of headwater streams under present day conditions and future climate change scenarios. In this image, lead researcher Kyle Leathers uses a home-built device to capture insects as they emerge from their nymphal stage, which they spend in the water, into their adult stage, which they spend on land or flying in the air. The team built the device using PVC pipes and mesh, and added pool noodles to help it float.
