SPATIAL AND TEMPORAL VARIABILITY OF AQUATIC INSECT EMERGENCE IN POOL 8 OF THE UPPER MISSISSIPPI RIVER
Large rivers transport nutrients and energy from aquatic to the terrestrial ecosystems via insect emergence. In addition, these rivers provide diverse habitats, ranging from main channel to floodplain, and dynamic environmental conditions. However, little is known about how spatial and temporal variability influences insect emergence. In the study, we quantified spatial and temporal variability in insect emergence diversity and abundance across Pool 8 of the Upper Mississippi River near La Crosse, WI, USA. Physicochemical data and insect emergence were collected at nine different sites, that varied in distance from main channel (far, mid, close). Dissolved oxygen levels were elevated in the far distance sites compared to the close and mid distance sites, however, there were no differences in temperature, pH, and conductivity. Preliminary results of emergence (n=14) suggest community diversity and evenness are affected by distance from main channel. Future processing of samples will aim to quantify peaks in emergence timing. Identifying hotspots and hot moments in insect emergence will help managers better promote and protect this important aquatic-terrestrial transfer of energy.
