WHAT THE EVIDENCE SAYS
An accepted peer-reviewed analysis compared abundance, F index, importance value index and h index. F index emphasized widely distributed species; IVI shifted rankings through basal area, and h index classified more narrow-distribution species as dominant.
WHY IT MATTERS / OUR READ
Managers should define dominance according to a decision's purpose: abundance, biomass or geographic prevalence.
CAVEATS / UNCERTAINTY
Metric-dependent differences are not evidence that one index fits every ecosystem. Peer-reviewed accepted record is not yet final formatted.
