並列タイトル等Community-wide effects ofbelowground rhizobia on aboveground herbivore and predator arthropods
一般注記1. Plants take nutrients for their growth and reproduction from not only soil but also symbiotic microbes in the rhizosphere, and therefore, belowground microbes may indirectly influence the aboveground arthropod community through changes in the quality and quantity of plants. 2. Rhizobia are root-nodulating bacteria that provide NH4+ to legume plants. We examined the effects of rhizobia on the structure of the atihropod community on host plants, using 28 pots of a root-nodulating soybean strain (Glycine max L.: R+) and 48 pots of a non-nodulating strain (R-) in a common garden. 3. R+ plants grew larger and produced a greater number ofleaves than R- plants. We observed 33 and 29 arthropod species on R+ and R- plants, respectively. They were classified into sap feeders (12 species), chewers (16 species), predators (3 species), and unknown (5 species). 4. The species richness and abundance of herbivorous arthropods on R+ plants were greater than those on R- plants. Rhizobia positively affected the abundance of both sap feeder and chewer herbivores. The community composition of arthropod herbivores was significantly different between R- and R+ plants. 5. Likewise, the abundance and species richness of the predators on R+ plants were greater than those on R- plants. 6. Greater species richness of herbivores increased the species richness and abundance of predators. Greater abundance of herbivores increased the species richness of predators, although it did not influence predator abundance. 7. These results indicate that aboveground arthropod communities were largely driven by the belowground microbes.
