Numerical ecology of coccolithophores and their life cycle
	Coccolithophores play an important role in the carbon cycle because of their formation of calcium carbonate platelets called 'coccoliths'. Their impact on the carbon cycle is however highly dependent on the abundance and type of coccolithophore present - as calcification, growth and sinking rates vary widely between species. Nonetheless, representation of coccolithophores in biogeochemical models is usually limited to single functional types. Trait based approaches - which model traits such as size instead of individual species - offer a promising avenue for better representation of coccolithophores in models. Yet, it is not clear which coccolithophore traits are most appropriate or how they can be represented numerically.
	Here I explore coccolithophore traits using an integrated approach combining modelling and laboratory experiments - with a specific focus on the coccolithophore life cycle. Additionally, using machine learning approaches I provide the first species specific global coccolithophore standing stock estimates, which is contextualized with the question: "do we actually need to represent higher coccolithophore biodiversity in models?"
