The effects of fire severity on ectomycorrhizal colonization and morphometric features in Pinus pinaster Ait. seedlings

<p><em>Aim of the study:</em> Mycorrhizal fungi in Mediterranean forests play a key role in the complex process of recovery after wildfires. A broader understanding of an important pyrophytic species as <em>Pinus pinaster</em> and its fungal symbionts is thus necessary...
