Sponge-Nitrifier Associations

For the purpose of this text on symbioses as they relate to the marine nitrogen cycle, we wiU first emphasize the more common open ocean diatom-diazotrophic associations (DDAs), then summarize the recent advances in our understanding of sponge-nitrifying microbial associations, and provide brief introductions to a few other relevant symbioses. In addition, we recommend, the chapter by O Neil and Capone (Chapter 21) for details on algal-animal symbioses of Coral Reefs as they relate to the nitrogen cycle. Chapter 4 by Carpenter and Capone on Nitrogen Fixation and Chapter 5 by Ward on Nitrification.
