Not every nonnative species becomes invasive. Understanding the difference among introduced, established, and invasive species is essential for interpreting biological invasions, including Burmese pythons in Florida.
Burmese pythons once seemed like unlikely large-scale invaders, but their size, diet, reproduction, maternal care, low energy needs, and low detectability help explain why they became such a formidable ecological problem in Florida.
Large Burmese pythons are physically capable of killing a person, but no human death has been attributed to a wild python in Florida. The real question is how to think clearly about low-probability but real risks.
Burmese pythons do not only affect the animals they eat. By reducing mammalian predators such as raccoons and opossums, they may indirectly alter turtle nest predation in South Florida.
The 2012 PNAS study documented severe declines in several mammal species in Everglades National Park during the same period that invasive Burmese pythons became established and widespread.
Burmese pythons are difficult to manage partly because they are so difficult to detect. A snake can be present, nearby, and still effectively invisible.
No reliable estimate exists for the number of Burmese pythons in Florida, largely because the snakes are cryptic, unevenly distributed, and extremely difficult to detect.
A single crab pot can kill many diamondback terrapins and severely affect a small local population. Research from Georgia illustrates the scale of the losses—and why preventing turtles from entering traps matters.
Crab pots disproportionately capture smaller diamondback terrapins, altering population age structure and sex ratios. Long-term research shows why counting deaths alone can miss the broader consequences—and how gear modifications can reduce risk.
The recapture of a diamondback terrapin first marked in 1986 connects four decades of research at Kiawah Island. Her history illustrates why understanding longevity, survival, and population change requires sustained field studies.
