Overview

Field experiments demonstrated predator biomass enhances herbivory and primary productivity in coral reefs, implying nutrient cycling dynamics.

Key Points

  • Increased predator biomass led to enhanced herbivory rates and productivity in nutrient-limited marine systems.
  • Field observations revealed that mesopredatory fish excreta are higher in phosphorus compared to nitrogen, impacting nutrient dynamics.
  • Predator-induced nutrient stoichiometry alterations were found to stimulate ecosystem processes beyond top-down effects.
  • The global decline of apex predators could significantly affect the balance of marine ecosystems and their resilience.
