Puerto Rico’s frogs reveal the island’s environmental health

Puerto Rico’s frogs, especially the coquis, are providing vital insights into the health of the island’s ecosystems as scientists use bioacoustics to monitor environmental changes.

Benji Jones reports for Vox.


In short:

  • Puerto Rico’s frogs, particularly the coqui species, are key indicators of ecosystem health, with their presence signaling a thriving environment.
  • Scientists use bioacoustics to monitor frog calls, which helps track changes in climate and environmental conditions across the island.
  • Research shows that many frog species are migrating to higher elevations due to rising temperatures, impacting the effectiveness of current wildlife reserves.

Key quote:

“Discerning whether 100 detected calls are from one bird in mating season or dozens of less active individuals remains challenging. Estimating population density through bioacoustics is still quite complex.”

Why this matters:

Understanding frog populations and their movements can help scientists gauge the impact of climate change and guide conservation efforts, ensuring the protection of biodiversity and ecosystem health in Puerto Rico. Read more: The health of wildlife is inseparable from our own.
