Distance-based redundancy analysis (db-RDA) of the influence of cover crop type in each tillage management system on the communities of arbuscular mycorrhizal fungi (AMF) in the maize roots. Dashed lines explain the effect of each type of cover crop. Ellipses represent 95% confidence intervals. A: rotary tillage, B: no tillage. All analyses and Fig. 6 were run and created in the software environment RStudio (Version 1.2.1335 – © 2009–2019 RStudio, Inc.) (http://www.rstudio.com).
