“Hitchhikers” on ships and planes – globalization of trade and tourists drives modern “evolution” of species and ecosystems.
A section of War in the Pacific National Historical Park in Guam has been closed after the presence of the invasive little fire ants was discovered.
Pacific Daily News (http://is.gd/LJzSmU) says the Asan Beach unit of the park has been closed to reduce the possibility of spreading the little fire ants.
The closure also aims to protect the public from the ants, which are tiny but can produce painful stings.
Officials are considering several options to eradicate the pest from Asan Beach, including the application of pesticides, and cutting and burning infested trees.
The little fire ant was first discovered in Guam in 2011 and first found in Hawaii in Puna in 1999.
The species is native to South America.
