I wouldn't call Witt Gibbons a 'so called' Scientist. He's been in charge of the Savannah River Ecology Lab for quite some time, several decades I think. And is a very well respected herpetologist who has authored several papers and booklets on reptiles from serious studies to identification guides. Some people here may even have read his works without even knowing it. I believe he wrote, or wrote a large part of, the Boy Scouts Reptile merit badge guide.
I remember watching him give a talk about 15 or so years ago on one of his projects involving the study of snake ranges and tracking their movements using PIT tagging techniques. It was a very interesting talk, but what I remember best was his quirky sense of humor. The type of humor that would be very easy to misrepresent in a printed article. I don't doubt that he actually said what he is claimed to have said in the article, what I would like to know is how he said it and the tone of voice used.
I believe that this study will show very quickly, that burmese pythons can NOT survive as far North as was claimed by that stupid map. Then there would be actual PROOF, not just guesses.
