Hey all,
It is interesting to view the reactions to the subject of my lecture. Such reactions are to be expected, given that they represent the normal expression of conventional wisdom on the subject.
I explained in my lecture that the opinions I was expressing had their foundation in a very interesting book called Invasion Biology Critique of a Pseudoscience, by David I. Theodoropoulos.
You can read about the author and find links to some of his publications at:

On the subject of the post from jman77, well I can't help it if some people lose respect for me for sharing these ideas. I hope some of you who read my reply will investigate this subject further and form your own opinions. I do realize there is a mountain of scientific papers pushing the idea of invasion biology, I am not ignorant of that. Science does not work by concensus. On the contrary, it progresses through novel thinking.
See the following link to a lecture by Michael Crichton for a fascinating discussion of that idea:

I take no credit for the novel thinking about invasion biology-- I only recognize the wisdom in Theodoropoulos' ideas, and hope to share it.
Regarding Melaleuca, one only has to view it from an airplane to fully appreciate what it does. It was planted to dry up sections of the everglades to prepare them for land development/construction, since it grows densely, transpires a lot of water, and thus dries up the wetland. However, viewed from the air it is clear that dense stands grow only along the margins of the everglades already damaged by construction.
Similarly Brazillian pepper is limited to deeply plowed areas, such as along the side of the road or farmland. It often grows in a line on plowed substrate right next to uninvaded, undamaged native forest.
I am not aware of any harm done by iguanas, aside from scaring the *#%& out of people not expecting a 4 foot reptile in the backyard. OK, maybe if you grow a particular type of non-native flowering plant you might get upset if the iguanas ate the flowers.
Pythons are scary too, but has there been or will there be any harm from them here?
Quaker parrots seem to be filling a niche once belonging to a native species of parrot that once ranged from Florida through the Carolinas-- it is now extinct. There are many more species of parrots now flying around south Florida. When they hit my Mango tree and damage the fruit I get annoyed, but of course the Mango is not native here either.
Piranhas. I tend to agree that they would not be welcome here in Florida! Call me a hypocrite!
Caulerpa-- a much maligned and distorted subject of invasion biology "research."
I refer interested readers to the following recent paper kindly sent to me by professor Jean Jaubert:
