Non-native Cuban treefrogs have established a breeding population in New Orleans, Louisiana, the first such population on the U.S. mainland outside Florida. The treefrogs were discovered at the Audubon Zoo shortly after a shipment of palm trees from Florida were planted in the zoo's elephant enclosure in 2016.

Laboratory technician Amelia Ulmer filters water collected in the field, to be analyzed for environmental DNA in the laboratory of Dr. Margaret Hunter. This sample was tested for Burmese python eDNA, in a process similar to that developed by Dr. Hunter for manatee eDNA.

A juvenile Broad-banded Watersnake that tested positive for snake fungal disease (SFD) exhibiting numerous nodules overlaid by roughened skin on the dorsal surface from St. Martin Parish, Louisiana. "FD has proven lethal in many snakes, and the disease is recognized as an emerging threat to wild snake populations.

To understand how changes in rainfall and temperature might affect coastal wetlands in the northern Gulf of Mexico, USGS researchers conducted field studies at 10 estuaries in five states (Texas, Louisiana, Mississippi, Alabama, and Florida). The fieldwork took place in a variety of coastal wetland types, including mangroves, marshes, and salt flats.
