A news story from Wildlife Conservation Online produced by the Wildlife Conservation Society. This story provides a good description of the coyote's coming to Florida.  "The ecological impact of the coyote’s quiet march into Florida may not be clearly understood for decades. “It’s a huge ecological experiment in which we have the chance to get data from the start,” sums up Main. As information flows in from the efforts of biologists like Hershberger, the picture will come into sharper focus."  

I know that in the 1970s and 80 you never saw a coyote or coyote road kill in Florida.  Now they appear as one of the more common species.  What I'd like to know is were coyotes here in the past, before Florida was developed.  Like the Buffalo.
