That is, although differences between the two sites were only marginally significant, L. variegata seemed more strongly limited by PO 4 3− (Two Proportion Z-test; Z = 1.90; df = 70; P = 0.05) and less strongly limited by NO 3 − (Two Proportion Z-test: Z = −1.79; df = 70; P = 0.07) at Buoy 0 than at Playa Kalki ( Fig. 6 ).
