Fern mycorrhizae do not respond to fertilization in a tropical cloud forest
In the present study, we revisited cloud forest plots fertilized with nitrogen and phosphorus for 15 years to assess the root-associated fungi of two epiphytic and two terrestrial fern species. We sampled two replicates per plot (four plots each of nitrogen, phosphorus, and nitrogen + phosphorus fertilization and control) for a total of 125 specimens, and sequenced the root-associated fungi following a metabarcoding approach.
