Invasion

Invasion Description

Gulf and Atlantic Coast populations appear to be genetically distinct at some loci, with an apparent boundary near Ocklochonee Bay (NE Gulf of Mexico)/FL (Foltz et al. 1995). This could indicate that Atlantic Coast populations are derived from Florida Gulf or Florida-Atlantic populations. The invasion status of Florida Atlantic populations is uncertain.
