Implication

Randomized trial investigates seagrass meadow conditions' impact on soundscapes, suggesting conservation strategies.

Key Points

  • This study aims to validate how soundscape structure relates to seagrass meadow conditions and human activity.
  • Analyzed soundscape recordings from 16 sites in Mediterranean Marine Protected Areas over 6,600 recordings.
  • Examined the influence of seasonal patterns and anthropogenic disturbances on acoustic metrics.
  • Explored the relationship between habitat structure, biological processes, and acoustic characteristics.
  • Site-specific soundscapes were identified, with diel cycles leading to increased nocturnal sound associated with fish and invertebrates.
  • Denser seagrass meadows showed enhanced acoustic metrics but reduced low-frequency sound levels due to the canopy's acoustic attenuation.
  • Boat noise significantly reduced acoustic complexity and biodiversity, emphasizing human impacts on marine soundscapes.
