The ability of genera to utilize organic nutrients indicates a competitive advantage of these genera compared to inorganic nutrient preferring genera when organic nutrients are available.

All three coccolithophores were able to utilize a range of different organic nutrients, but two species did not grow on some organic nutrients.

Species which are not able to utilize organic nutrients may be nitrogen or phosphorus limited under a decreased inorganic to organic nutrient ratio. These limitations may affect silicification and calcification and therefore change biogeochemical cycles. @Bremen, Univ., Diss., 2008 Text North Atlantic Georg-August-Universität Göttingen: GOEDOC |
