We often hear that the barometer is really measuring the weight of the column of air above us. This explains variations in altitude within a reasonable range above the surface, but in the interior gravity drops off and eventually goes to zero. Is there a point where pressure ceases to increase or does it continue all the way down?

Are Florida’s invasive species (Burmese pythons, green iguanas) inbred?

I recently moved to south Florida and discovered that many of the invasive species were initially introduced to the environment through the pet trade.

I understand that with endangered animals, one major concern is whether the remaining population is enough to prevent inbreeding and population drift. The 50/500 is generally used as a rule of thumb in determining this.

My question is, are the populations of iguanas and boas in south Florida inbred? I can't imagine so many individuals being released initially by pet owners so I would assume compared to the native population of these creatures that they have some inbreeding.

Followup question. These species appear to thrive in south Florida. Now that ownership and possession of these species is strictly regulated, there will likely be no to very very little new genetic diversity introduced. Will the current populations be sustainable over time?
