Estimation of dispersal distances of the obligately plant‐associated ant Crematogaster decamera

Abstract: Abstract. 1. In obligate symbioses with horizontal transmission, the population dynamics of the partner organisms are highly interdependent. Host population size limits symbiont number, and distribution of partners is restricted by the presence and thus dispersal abilities of their respective partner. The Crematogaster decamera -Macaranga hypoleuca ant-plant symbiosis is obligate for both partners. Host survival depends on colonisation by its ant partner while foundress queens require hosts for colony establis… Show more

“…Although we did not directly investigate dispersal mechanisms or food resources, C. pilosa likely has the potential to colonize the entire salt marsh but will establish only in areas with adequate resources and habitat. Most ants, including other Crematogaster species, have winged reproductive castes allowing the species to populate new environments (e.g., Türke et al 2010). We found ants on islets within tidal creeks, indicating they have a dispersal strategy allowing them to colonize areas not connected to current populations.…”

“…Because plant ants usually swarm at night and find their host over comparably large distances (Türke et al . ), many of them use volatile organic compounds (VOCs) in their host‐finding behavior. The queens of both Azteca and Allomerus ants are attracted to the VOCs emitted by C. nodosa plants, which suggests that they use olfactory cues for the long range detection of their host plants (Edwards et al .…”

“…Theory suggests that interspecific differences in the dispersal capability of ant queens play a key role in the maintenance of diversity in these communities, either via tradeoffs between dispersal ability and other life-history traits (e.g., competitive ability, colony fecundity), or from the interaction of dispersal limitation with spatial heterogeneity in host-plant density (reviewed in [3]). Studies in multiple plant-ant systems have demonstrated inequities in the competitive ability of ant queens or colonies [16], [17], plant and colony distribution consistent with habitat partitioning and patch dynamics [18], [19], and patterns of colonization that imply dispersal limitation [8], [12], [20] or interspecific variation in dispersal ability [20], [21]. Nevertheless, drawing general conclusions regarding the importance of dispersal for plant-ant coexistence requires quantitative descriptions of dispersal for multiple ants competing for access to the same host-plants.…”
