Figure 8. A) Alligators in the L-40 canal in the Arthur R. Marshall Loxahatchee National Wildlife Refuge. Alligator populations in canals tend to be dense and dominated by adults. Photographer: Brian Jeffery, University of Florida. B) Adult alligators that rely on canals may no longer construct and maintain alligator holes, which could adversely affect populations of marsh fishes, amphibians, and wading birds that rely on alligator holes for dry-season habitat.
