文摘

The effects of a mud snail, Cipangopaludina chinensis laeta (Martens) (Architaenioglossa: Viviparidae), on terrestrial arthropods through rice plant development in a paddy field were investigated in 2013 and 2014 by a field experiment. There were no significant differences between treatments in the abundance of aquatic organisms, which comprised several functional feeding groups in both years. The presence of mud snails did not significantly affect plant height and soil plant analysis development values, either, except in June 2014, when tiller number and biomass of the rice plants tended to be larger in plots with snails versus those without. Significantly higher abundances of terrestrial organisms, including phytophagous pest insects and other insects, but not natural enemies of the pest insects, occurred in plots with snails. As shown by principal component analysis, the community structure of the terrestrial organisms was significantly different between the two treatments in both years. The results of this study indicate that mud snails play an important role in the paddy field ecosystem, in which they influence the biomass production of rice plants and the abundance of organisms in terrestrial ecosystems through direct and indirect interactions at different trophic levels.
