The Essential Rhythm 6/26/22: Attack of the clones

Producer/Host: Sarah O’Malley

This episode describes the complex phenomenon of self/non-self recognition in otherwise simple asexually reproducing animals, the anemones. Certain anemones are able to differentiate between their own clones and unrelated individuals in order to defend their territory. This research is featured in Adam Nicolson’s Life Between the Tides.

The Essential Rhythm 5/15/22: Shrimp have deep thoughts too

Producer/Host: Sarah O’Malley

This episode features insights from Adam Nicolson’s Life Between the Tides and describes the parallels between the nervous systems of shrimp and humans. Both animal lineages have fast reacting, non brain linked neural pathways that drive life saving behaviors (sometimes called a “startle response” or reflex).

The Essential Rhythm 5/8/22: Sand fleas are smarter than you think

Producer/Host: Sarah O’Malley

This episode describes the water retaining properties of the exoskeleton of sand fleas as well as research into their unexpectedly complex navigational systems. Together these allow them to forage in the intertidal zone, breaking down organic matter and recycling nutrients.
