The American alligator, Alligator mississippiensis, has long been considered a keystone species in the Greater Everglades Ecosystem, largely for its role in the creation and/or maintenance of aquatic refugia. Alligator holes have historically been viewed as critical habitat for a wide range of aquatic species, particularly during the dry season.

This study aims to clarify both the spatial and structural extent of alligator holes in the Arthur R. Marshall Loxahatchee National Wildlife Refuge. Furthermore, the study helps clarify the ecological function of such refugia, and ties their existence to localized increases in plant diversity.
