Abstract

We studied the distribution, mortality and association with plants, of 308 nests of the neotropical ant Paraponera clavata, in a pennanen! 50 hectare plot in old-growth forest on Barro Colorado island between September 1993 and February 1995. Ant nests were unifonnly dispersed throughout the plot, and significantly associated wíth the high plateau and patch of young forest in the plot. The average densíty was 6.2 nests per hectare. Mortality of nests was higher with increasing number of neighbors within 20 m, compared to those separated at greater distances. The mortality was between 13.36% and 69.64% depending on the census interval, and recruitment between 22.63% and 31.72%. The nests were found in 84 plant species of 34 families, pertaining to four life fonns: 76 species were trees, 5 were shrubs, 2 were palms and one was a liana. We tested for association between ant nests and lree species and tree size by examining whether nests were more common in certain categories Ihan would be expected by change. Eight species of plants were positively associated with Paraponera clavata. The ant preferentiallyand small shrubs were not associated with the nests. No association was found between ant nests and trees with extra-floral nectaries. Fifty-three percent of the nests had a Phrynus gervaisii (Amblypygi: Phrynidae) cohabiting ínside. These nests had lower mortality rates Ihan the resto
