Fig 1. Map of the study area.

Locations of Water Conservation Area 3A (WCA 3A) and Arthur R. Marshall Loxahatchee National Wildlife Refuge (LOX) in the Everglades of Florida, USA, and inset maps of adult female alligator capture sites. In capture-site maps, habitat type shows the densities of tree islands (clusters of trees / shrubs) and locations of canals near capture sites; white areas in the LOX inset are non-habitat. Open-source data for habitat type were obtained from the Ecological Modeling Team at Everglades National Park: http://simglades.org/.
