Burmese pythons — an invasive species in south Florida — could find comfortable climatic conditions in roughly a third of the United States according to new “climate maps” developed by the U.S. Geological Survey. Although other factors such as type of food available and suitable shelter also play a role, Burmese pythons and other giant constrictor snakes have shown themselves to be highly adaptable to new environments. Non-native giant constrictor snakes, such as the Burmese python are now spreading from Everglades National Park in Florida. New “climate match” maps show where climate in the U.S. is similar to places in which Burmese pythons live naturally (from Pakistan to Indonesia). A look at the map shows why biologists are concerned.
