In Table 3, the rows of the two sections should be differently labelled (below).

Table 3. Relative yields of the eight species grown in all pairwise combinations at two sowing densities (5 and 1 g /m2). Note that we give inverse measures of competitive effects. Species of similar competitive responses and effects (Tukey’s studentized test, P B/ 0.05) are denoted by common superscripts. Using the Mann-Whitney U test, we compared all related means in the two seed-sowing densities treatments (*PB/0.05; **PB/0.01). Species names are abbreviated as in Table 2.
