Ants and Plants with Extrafloral Nectaries; a comparison of fire successional habitats on Andros (Bahamas).

WE surveyed the abundance of nectar-drinking ants in pineyard and coppice habitat on Andros in the spring of 2004. Using transects honey baits to attract ants, we found more ant activity in pineyard than in coppice habitat. We were surprised to find the greatest ant activity in recently burned pineyard, followed by open pineyard, overgrown pineyard, coppice edge, and coppice. We sampled the vegetation using linear transects, and found the proportion of plants bearing extrafloral nectaries to be higher in pineyard than in coppice. Our results (similar to patterns observed in the Florida Everglades) suggest that ant protection against herbivores may be more important in earlier successional than in later successional habitats in the Bahamas, a hypothesis that warrants further experimental investigation.
