Table 2 Statistical output for linear mixed-effects model (LMM) fit providing marginal and conditional R2 values. P-values, chi squared (χ2), and degrees of freedom (df) obtained from likelihood ratio tests for effects of treatment and temperature. Data are divided by species. Total number of observations for each analysis: Ulva = 240, Hypnea = 286. Random effects in parentheses below R2c (a = plant ID, b = run, c = RLC order, d = lunar phase).

From: Divergent responses of native and invasive macroalgae to submarine groundwater discharge
