Table 3 Understory structure (species richness, strata quantity) and general ground cover types (bare soil, debris and vegetation) in Nothofagus forests of Tierra del Fuego, according to forest type (deciduous, mixed, or evergreen) and landscape location (coast or mountain)

From: The influence of canopy-layer composition on understory plant diversity in southern temperate forests

  1. F(p) = Fisher statistic with probability between brackets. Different letters show differences by Tukey test at p < 0.05
  2. The variable vegetation was ln(Y + 1) transformed for the analysis to accomplish ANOVA assumptions, but not transformed data are shown
