Fig. 2: Symptomology in nature: biocrust plaques.
From: High impact of bacterial predation on cyanobacteria in soil biocrusts
Main: Macroscopic view of a soil surface colonized by cyanobacterial biocrusts and impacted by multiple plaques as taken after a rain in a quadrat used for field surveys. Insert: Close-up of a single plaque, showing well-demarcated boundaries and a typical central area of new cyanobacterial colonization.
