The limiting factor that would have the greatest impact on alligator populations in Florida is likely the availability of suitable habitat, particularly freshwater wetlands. Alligators rely on these ecosystems for breeding, feeding, and thermoregulation. Changes to their habitat due to factors such as urban development, pollution, water management practices, and climate change can significantly affect their population dynamics.
Additionally, water quality and the availability of prey (such as fish and small mammals) are also critical factors that can limit alligator populations. Any significant alteration in water levels or quality, or depletion of prey resources, can directly impact their survival and reproduction. Therefore, maintaining healthy and stable wetlands is essential for supporting robust alligator populations in Florida.
