Considerable impacts of litter inputs on soil nematode community composition in a young Acacia crassicapa plantation

Aboveground litter inputs and root exudates provide basal resources for soil communities, however, their relative contributions to food web are still not well understood. Here, we conducted a field manipulative experiment differentiate the effects of living on nematode community composition surface subsoils in young Acacia crassicapa plantation southern China. Our results showed that both addition presence significantly enhanced abundance by 17.3% 35.3%, respectively. Litter altered trophic group composition, decreased fungivore bacterivore ratio, maturity index structure index, which led bacterial-based energy channel more complex structure. However, had limited impact ecological indices. Despite nematodes assembly, depth did affect or index. findings highlight importance shaping regulating channel.
