  1. For the explanatory values, see Table 1. “*” and “**” indicates P < 0.05 and 0.01 in GLMM analyses, respectively. Skew of nymphoids could not be analyzed because of small numbers of colonies producing nymphoids (3 of 13 sister-pair colonies and 3 of 14 unrelated-pair ones, see Additional files 1, 2 and 3).
