Evidence for a Dome-Shaped Relationship Between Turbulence and Larval Fish Ingestion Rates by MacKenzie, Brian R., Miller, Thomas J., Cyr, Stephane, Leggett, William C.

Metal provisioning of ova in walleye and lake whitefish by Johnston, T.A., Wiegand, M.D., Mittermuller, S., Casselman, J.M., Pyle, G.G., Leggett, W.C.
