Treatment	Total coccolithophores	E. huxleyi	R. clavigera	E. huxleyi mass
C		+NH4+ (p = 1.4 × 10–2)	–NO3– (p = 2.6 × 10–2)
W	+ PO43– (p = 7.0 × 10–2)		+PO43– (p = 8.6 × 10–2)
OA		+NO3– (p = 3.0 × 10–2)		+ PO43– (p = 5.0 × 10–3)
GH	+NO3– (p = 7.0 × 10–3); + NH4+ (p = 2.8 × 10–2)	+NO3– (p = 8.7 × 10–2)	+NO3– (p = 5.5 × 10–2); +NH4+ (p = 1.0 × 10–3)	+ NH4+ (p = 4.9 × 10–2)

The positive (negative) signs indicate direct (inverse) significant relationships between the coccolithophore parameters (i.e. coccolithophore cell abundance and E. huxleyi coccosphere calcite mass) and nutrient concentrations. The correspondent p-values are indicated within parentheses.
