Abstract:Results supported an important role for juvenile crayfish in both systems. At Jordan Creek, juveniles were >10 times more abundant than adults during summer and likely accounted for the majority of crayfish effects in the stream. At Shivering Sands Creek, small crayfish greatly reduced the abundance of many invertebrate taxa and also accelerated leaf litter breakdown rates within enclosures. In times and places where they are abundant, juvenile crayfish may strongly modify ecosystem processes and benthic invertebrate assemblages in streams.
