Moss Transplants in the Tundra Reveal Host-Specific Microbiomes and Nitrogen Fixation Responses

Rebecca S. Key, Julia E. M. Stuart, Stuart F. McDaniel, Michael Hoffert, Emily Lockwood, Noah Fierer, Hannah E. Holland-Moritz, Michelle C Mack

This study transplants mosses between tundra sites to show that nitrogen fixation rates are more influenced by host species and microenvironment than microbiome changes.
