A major research program at CBFS is the Oneida Lake projects involving two of CBFS’ senior scientists: Jackson concentrating on fish and fisheries and Rudstam concentrating on lower trophic levels. Paul Curtis continued his work on colonial waterbirds in the lake while Rebecca Schneider studied ground water phosphorus input with PhD student Sol Lisboa. Roxanne Razavi worked with mercury contamination in sport fish as affected by round goby. Amy Hetherington completed her analysis of mussel dynamics in Oneida Lake and worked with Dave Strayer on an analysis of dreissenid mussel dynamics across world lakes. Karim Kassam with graduate student Leo Louis worked on the ecological calendar, and Alexander Karatayev and colleagues used Oneida Lake and similar data from three polymictic Belarusian lakes to study the long-term effects of zebra and quagga mussels on the ecosystem. The Oneida program depends on our dedicated research staff Brooking, VanDeValk, Holeck, and Hotaling. Oneida Lake is a site member of the Global Lakes Ecological Observatory Network (GLEON) and part of several research projects comparing data from lakes across the world. The fisheries data was used by research groups at USGS (Kao, Bunnell) and DFO Canada (Hossain, Koops), and NOAA-GLERL (Rutherford, Mason, Zhang), all three groups working on the coupling between phosphorus and fish using Oneida data and Great Lakes data. Nelson Hairston, Steve Ellner, and Lindsay Schaffner with international collaborators wrapped up a study on eco-evolutionary dynamics in Daphnia (in Nature Ecology and Evolution). It has been an active year on Oneida Lake and the interest from collaborators shows the value of CBFS long-term data.
