Salt Water Alone Unlikely to Halt Burmese Python Invasion

Gainesville, Fla. - Invasive Burmese python hatchlings from the Florida Everglades can withstand exposure to salt water long enough to potentially expand their range through ocean and estuarine environments, according to research in the latest issue of the Journal of Experimental Marine Biology and Ecology.

This recent study, based on lab experiments conducted by researchers from the U.S. Geological Survey, provides initial evidence that pythons may be able to survive in marine and estuarine environments such as bays, inlets and open seas. The results raise concerns that the invasive constrictor may invade nearby islands, such as the Florida Keys, said Kristen Hart, a USGS research ecologist and lead author of the study. arrow iconUSGS News Release>>

Famous Manatee Sighted in Chesapeake Bay After Long Absence

Gainesville, Fla. – A manatee spotted this week in Calvert County, Maryland is the same one that first made waves 17 years ago when he appeared in Chesapeake Bay just before the onset of winter and later had to be rescued.

Named "Chessie," the manatee's identity was verified by U.S. Geological Survey biologist Cathy Beck, who used photos taken July 12 and matched them with Chessie's photographic record in a USGS manatee database. Chessie's tell-tale markings include a long, gray scar on his left side. arrow iconUSGS News Release>>

Extent and Speed of Lionfish Spread Unprecedented

The rapid spread of lionfishes along the U.S. eastern seaboard, Gulf of Mexico, and Caribbean is the first documented case of a non-native marine fish establishing a self-sustaining population in the region, according to recent U.S. Geological Survey studies. arrow iconUSGS News Release>>
