3-factor ANOVA (analysis of variance) results for dark and light chamber NH₄⁺ flux and NH₄⁺ uptake.

<p>Factors are site (Sd = Sandy, Ms = Muddy-sand), season (Wi = Winter, Su = Summer) and treatment (+AS = <i>Austrovenus</i> addition, –AS = <i>Austrovenus</i> removal). Values in bold are significant at <i>p</i><0.05. Tukey post-hoc tests for significant differences between site, season and treatment are shown at α = 0.05.</p><p>Dark NH₄⁺ flux was log₁₀ transformed prior to analysis.
