Worm munch matters

Earthworms produce detectable sounds despite lacking a discernible mouth, sound-making organs, and ears.

The US Navy's SOSUS network, built to track Cold War submarines, mistook whale calls for the 'Jezebel Monster.'

@juneselby added

Healthy soil often sounds busier because it supports greater biological diversity and abundance.

@juneselby added

Continuous recordings found activity peaked after midnight with earthworms most active, while rewilded grassland had greater biodiversity than intensively grazed pasture.

@juneselby added

Distinct ecoacoustic measurements separate recovering forests from degraded soils, turning soil health into a soundscape.

@juneselby added

Buried hydrophones and acoustic probes reveal ant-nest rustling, beetle-larva clicks, and earthworm activity underground.

@juneselby added

Buried passive acoustic sensors could monitor soil continuously for days across many locations at once.

@juneselby added

Rachel Carson used vanished spring birdsong to expose DDT-driven ecological collapse after thinned eggshells caused reproductive failure.

@juneselby added

Matching soil sounds to broad functional groups may work better than identifying species, revealing why soil health differs between sites.

@juneselby added

Soil type and moisture alter sound transmission, yet their effects remain poorly understood and can confound comparisons between sites.

@juneselby added

Healthy soil sounds different from depleted soil because its animals, physical properties, and structure differ.

@juneselby added

Underwater acoustic monitoring revealed whale and dolphin movements across oceans that land or boat sightings could never fully track.

@juneselby added

Bioacoustics reveals sensory worlds otherwise inaccessible, including how bats experience echolocation and sound.
