The Florida panther, Puma concolor coryi, is one of the most threatened species on Earth, with only 80-00 individuals remaining. Their population is most threatened by humans, habitat loss, and their own poor health due to genetic diseases. Some conservationists want to introduce new individuals from Texas, the mountain lion, Puma concolor. Scientists are currently uncertain whether the Florida panther and the Texas mountain lion are the same or different subspecies.Many areas in Florida are set aside as preserved lands, especially in the Florida Everglades National Park, National Forests, and numerous state parks. However, these areas are fragmented and often bisected by large highways. One strategy to preserve biodiversity in Florida has been to create tunnels at intervals
underneath the highways. What functions do these tunnels serve?
A. Minimize edge effects
B. Create a single large reserve
C. Provide movement corridors
D. Create a flagship species
E. Simulate island biogeography
