Study Notes
- Invasive species can wreak havoc on ecosystems by outcompeting native species and causing imbalances.
- The U.S. government is using creative methods to combat invasive brown tree snakes in Guam, such as air-dropping dead mice filled with acetaminophen, which has been highly effective in killing the snakes.
- Lionfish, invasive predators in the Atlantic Ocean, are being targeted using human-controlled, pressure-resistant robots designed to stun and vacuum them, with the potential for the captured lionfish to be served at restaurants.
- In the Upper Missouri River Basin, researchers are utilizing backpack electrofishing to safely remove invasive brook trout without harming native fish populations.
- In Olympic National Park, invasive mountain goats are being airlifted to their natural habitat in the Cascade Mountains to protect the park's ecosystem, as they have become aggressive and addicted to human pee.
- Stragglers of invasive species can be challenging to eradicate, as seen on Isabela Island in the Galapagos where researchers used chemically altered "Judas goats" to track down and eliminate the remaining goats after a mass culling effort.- Judas goats, unable to reproduce, are left to live out their lives alone after other stragglers are gone.
- Significant resources are required for creative methods to combat invasive species.
- Simple actions like cleaning shoes after hiking or planting native plants can help control invasive species in local areas.
- Taking small steps like these can contribute to maintaining balance in ecosystems.
