Episode notes
Fungus Uses Environmental Cues
- The fungus uses environmental cues like light, temperature, and humidity to place ants precisely in a narrow band optimal for fungal development.
- Experiments shading graveyards reduced new infections and fungal reproductive success, implicating light as a key cue.
The Death Grip Is Regionally Tuned
- The 'death grip' (mandible clamp and leg wrapping) secures the ant in place and varies by region: leaves in tropics, stems in temperate zones.
- Shifts from leaves to stems evolved repeatedly to match local phenology and keep the fungus present longer.
A Resin Zombie Ant On The Desk
- Kelly describes finding a North Carolina zombie ant and keeping a resin-mounted specimen on her desk as a prized object.
- The specimen shows a stem, leg wrap, mandible bite, and a fungal stalk, and she treasures it.
