Abstract

The spatial heterogeneity in soil properties as well as in molecular and catabolic diversities of the soil microbial community were investigated by soil analyses, Illumina MiSeq sequencing and MicroResp™ profiling, respectively, in 51 plots of a 20 year-old eucalyptus plantation in south Brazil. The relationships between these parameters were assessed to test whether small scale variation in soil properties and understory vegetation generated heterogeneity in the soil microbial community. The spatial variability of soil microbial community and functioning was shown to be substantial. A greenness index, used as a proxy of the density of the understory biomass, explained very little of the soil microbial parameters. Variability in soil properties (mainly C availability, pH) partly explained shifts in molecular and catabolic parameters of the soil microbial community. Bacterial (and, to a lower extent, fungal) molecular parameters were the main factors explaining the catabolic capabilities of the soil microbial community. But overall, the sequencing data was of little use in explaining C processes in these soils, underlying the difficulty in predicting the contribution of large tree-plantations to the global C cycle.

通过土壤分析、Illumina MiSeq 测序和 MicroResp™ 图谱分析,分别对巴西南部一个 20 年树龄的桉树种植园的 51 个地块的土壤性质以及土壤微生物群落的分子和分解代谢多样性的空间异质性进行了研究。对这些参数之间的关系进行了评估,以检验土壤特性和林下植被的小尺度变化是否会导致土壤微生物群落的异质性。结果表明,土壤微生物群落和功能的空间变异很大。作为林下生物量密度代表的绿度指数对土壤微生物参数的解释作用很小。土壤特性(主要是碳的可用性和 pH 值)的变化部分解释了土壤微生物群落分子和分解代谢参数的变化。细菌(以及较低程度上的真菌)分子参数是解释土壤微生物群落分解能力的主要因素。但总体而言,测序数据在解释这些土壤中的碳过程方面作用不大,这也是难以预测大型植树造林对全球碳循环的贡献的原因所在。

期刊介绍: Applied Soil Ecology addresses the role of soil organisms and their interactions in relation to: sustainability and productivity, nutrient cycling and other soil processes, the maintenance of soil functions, the impact of human activities on soil ecosystems and bio(techno)logical control of soil-inhabiting pests, diseases and weeds.
