This is pretty exciting, as snails can reach high biomass, with obvious consequences for algal standing crop, not to mention other grazer taxa. It's going to be interesting to see what their abundances look like during the second summer of warming.

Snails (Radix peregra) are only found in Hengill's warmer streams, so one response to the experimental warming of Stream 7 that we hoped to see was snail invasion. It's happening.
