Ants and plants with extrafloral nectaries in urban and natural landscapes of south Florida.

Native plant species with extrafloral nectaries interact with ants in natural areas, but what happens to these associations in fragmented natural areas, gardens, and other urban places? Ants are attracted to extrafloral nectaries of native legumes in many genera (including Chamaecrista, Senna, Lysiloma, and Pithecellobium) and in several cases we have evidence that the ants may benefit plants by deterring herbivory by phytophagous insects. Many other species of these native plant genera grow as ornamentals or invasive species in south Florida, and serve as host plants for some of the same herbivore species as do the native plant species. We contrast the ant species associated with these plants in natural and urban areas, and use network analysis to compare ant/plant interactions in these two communities.
