Table 3.
Standard effect sizes for each trait from three different assembly tests. Significance was tested with one-tailed Monte Carlo tests SES < 1.55 indicates significant underdispersion and SES > 1.55 indicates significant overdispersion (P values are given in parenthesis). SESdiv: divergence component; abundances randomized within communities; SESric: richness component; trial swap randomization and Rao calculated with species occurrences; SES: trial swap randomization and Rao calculated with abundances; Traits are ordered according to SESdiv from significant overdispersion (top) to significant underdispersion (bottom). Bold figures indicate significance
