Episode notes
Prairie Dogs: Keystone Species
- Prairie dogs act as a keystone species, greatly impacting the grassland ecosystem's health and structure.
- They create habitats and maintain grassland features by clipping woody vegetation and building burrows.
Badgerinator Field Experiment
- Researchers used a taxidermied badger on a remote-controlled car, the "badgerinator," to test prairie dog alarm calls' effect on curlews.
- The experiment measured curlew nest defense reactions with and without prairie dog alarm call playbacks.
Prairie Dog Alarm Advantage
- Hearing prairie dog alarm calls boosts curlews' predator awareness significantly, tripling their hiding distance.
- Early warning provides critical survival advantage against predators like badgers.
