Evidence for managing herbivores for reef resilience
Mary K Donovan e outros, 2023 · Proceedings of the Royal Society B: Biological Sciences
Prohibiting herbivorous fish harvest at Kahekili increased parrotfish biomass when present by a factor of 1.1 (p = 0.040).

with the biomass when present 1.1 times higher after the closure (d.f. = 1931, t = 2.06, p = 0.040)
Contexto
What changed: A local ban on the take of herbivorous fishes and urchins was implemented at Kahekili, Maui in 2009. Comparison: Surveys from five years post-closure (2011–2016) compared to two years pre-closure (2008–2009). Limits: Observational before-and-after monitoring at a single managed reef without a randomized control.
