Evolution of Passerine Bird Sperm/Sperm Competition

In collaboration with Jan Lifjeld at the Oslo Natural History Museum, we are examining the proteins in sperm, seminal fluid and reproductive organs. This is part of a larger project funded by the Norwegian Research Council. Sperm, speciation and promiscuity - an integrated analysis of evolution in passerine birds awarded to Professor Lifjeld. The aim is to identify proteins important in male fertilization success and potential mechanisms for cryptic female choice, and to determine how the mating system influences the evolution of these proteins.
