SUCCESSION IN INVERTEBRATE COMMUNITIES IN SOUTHEASTERN BEAVER-CREATED WETLANDS
Beaver-created wetlands in the Southeastern US are typically unstable transitory systems resulting from a history of extreme sedimentation which created unstable stream beds and regional weather patterns. Beaver dams are regularly breached, rebuilt, relocated, or abandoned which results in complexes of newly-created, mature, and abandoned beaver wetlands within a stream network. To compare invertebrate communities among the three basic habitat successional stages, invertebrates were sampled in newly formed (created within 2 years; n = 4), mature (established for >15 years; n = 4), and abandoned wetlands (breached dams; n = 3) and associated streams (n=3) in October 2013 and May 2014 in Oconee National Forest in Georgia, USA. Each wetland type had a relatively high number of taxa (>60 families) and there was strong seasonal variation in invertebrate communities. In October, invertebrate communities differed among all successional stages, while in May only the mature beaver wetland communities differed from newly formed or abandoned ponds. Seasonal differences in community structure suggest that seasonal change as well as longer-term succession strongly control invertebrate community structures in these beaver wetlands.
