hawaiian ant flower networks nectar thieving ants prefer undefended native over Introduced Plants with floral defenses
Ecological Monographs, 2011Co-Authors: Robert R. Junker, Curtis C. Daehler, Stefan Dötterl, Alexander Keller, Nico BlüthgenAbstract:Ants are omnipresent in most terrestrial ecosystems, and Plants have responded to their dominance by evolving traits that either facilitate positive interactions with ants or reduce negative ones. Because ants are generally poor pollinators, Plants often protect their floral nectar against ants. Ants were historically absent from the geographically isolated Hawaiian archipelago, which harbors one of the most endemic floras in the world. We hypothesized that native Hawaiian Plants lack floral features that exclude ants and therefore would be heavily exploited by Introduced, invasive ants. To test this hypothesis, ant–flower interactions involving co-occurring native and Introduced Plants were observed in 10 sites on three Hawaiian Islands. We quantified the residual interaction strength of each pair of ant–plant species as the deviation of the observed interaction frequency from a null-model prediction based on available nectar sugar in a local plant community and local ant activity at sugar baits. As pred...
