Aquatic Invasive Species

Our final group project – a research note on Daphnia lumholtzi in Jordan Lake – is coming up!  D. lumholtzi is an exotic water flea that forms long tail, head, and neck spines, which may reduce its edibility for juvenile fish.  Its ecological impacts have been found to vary in different ecosystems, however, and very little is known about its effects in Jordan Lake (a reservoir near Apex, NC), not to mention its seasonal abundance.  The top figure are the D. lumholtzi and other zooplankton data collected by last semester’s Aquatic Invasive Species students, and the bottom figure are the updated data, with the final data point provided by students from our class. How do you think our research notes will compare to those from last semester?
