TABLE 1.

Significance of main and interaction effects of three substrates, open top chambers (OTCs), and irrigation on the concentrations of Pseudogymnoascus roseus DNA in soil at Mars Oasis averaged across all samplings (2009–2012) or in individual years. Values in bold are significant at p < 0.05. Note that the directions of changes in DNA concentrations in response to the main effects of the treatments and the two‐way interactions are shown as arrows (↑, increase; ↓, decrease), with fold changes in response to the main effects being shown after the arrows
