Fig. 5: Patterns in qPCR-based abundances of dominant diazotroph taxa.
From: UCYN-A/haptophyte symbioses dominate N2 fixation in the Southern California Current System

Distributions of UCYN-A1 symbiosis (A, D), UCYN-A2 symbiosis (B, E), and Het-2 (C, F) in May 2017 (A–C) and October 2017 (D–F). Stations and transects are indicated at the top. Stn. 14 (October, T4) is not included due to missing surface data. Diazotrophs present at low abundances or sporadically detected are not included (Tables S1 and S2).
