Table 3 Repeated measures ANOVA results for ln (biomass) as a function of time (repeated factor), disturbance frequency (DRI), disturbance type (Type), species, and their interactions. Multivariate tests are shown since the data violated sphericity. We used Roy’s largest root for data collected at Archbold Biological Station, Venus, Florida, USA, from 2005 to 2014, as it is the most powerful test in many circumstances (Field 2009). Similar results accrue with tests of within-subject effects in repeated measures ANOVA when corrected for violation of sphericity using Greenhouse-Geisser or Huynh-Feldt corrections
