Overview

Randomized trial investigates acoustic habitat differences in delphinids, suggesting key foraging and social areas.

Key Points

  • This research aims to explore how different acoustic signals used by dolphins relate to specific environmental conditions and the presence of fish.
  • Acoustic signals from delphinids were recorded using a wave glider over two months.
  • Environmental data collected included sound pressure level, temperature, depth, and fish presence.
  • Generalized additive models were used to analyze the relationship between signal types and environmental variables.
  • Unique environmental predictors for echolocation and whistles were identified, indicating different habitats for each signal type.
  • Predicted habitat suitability maps for delphinids and soniferous fish demonstrated distinct high detection areas.
  • Delphinid vocalizations were influenced by the presence of soniferous fish, highlighting potential predator-prey interactions.
