Plant invasions alter soil biota and microbial activities: A global meta-analysis

Plant invasion is a major component of global environmental change that can significantly alter soil biota, which are essential for organic matter decomposition and nutrient cycling in terrestrial ecosystems. However, the particular linkage between invasive plants, soil biotas, and enzymatic activities remains unclear. Here, we conducted a comprehensive meta-analysis using 688 paired observations from 107 studies to evaluate to the impact of plant invasion on soil biota, enzymatic activities and nutrient cycling. Our results showed that plant invasion significantly reduced herbivores (45%), detritivores (27%) and omnivores (45%) abundance, while allelopathy, woody invaders and forest ecosystems significantly reduced predator abundance by 47, 46, and 32%, respectively. Invasive plants also slightly reduced bacterial and fungal biomass, but significantly increased arbuscular mycorrhizal fungal (AMF) biomass, MBC and MBN by 29, 19 and 32%, respectively. Moreover, invasive plants had incons..., We selected peer-reviewed journal articles using Web of Science and Google Scholars and screened the identified records using Preferred Reporting Items for Systematic Review and Meta-analysis procedure (PRISMA). Primary studies that satisfied the following selection criteria were included: (1) studies specifically described the identities of invasive and native plants and investigated either in the field observational or experimental studies, (2) at least one of the soil functional groups, or microbial composition or enzymatic activity was measured simultaneously in the invasive and native plants using the PLFA method (Kong et al., 2011), (3) invaded sites and control or native plants were found in the same biotic and abiotic conditions, (4) the means and sample sizes of the selected variables were available or could be calculated from the related publications. In our meta-analysis, we only used the soil microbial community composition and structure, soil microbial biomass and their enz..., , # Plant invasions alter soil biota and microbial activities: A global meta-analysis

[Data for plant invasion effects on soil biota functional groups and microbial activities research project. ](https://doi.org/10.5061/dryad.hhmgqnkq5)The dataset includes authors name and year, invasive species, native plant species, growth forms, allelopathy and ecosystem types. In addition, response variables for plant invasion with control and treated data with mean, standard deviation and number of samples, geographic coordinates, continent and country included. Meta-analysis was conducted on soil biota functional groups, microbial activities and nutrient cycling to assess the effect-sizes of plant invasion on the response variables.

# 植物入侵改变土壤生物群落与微生物活性：一项全球荟萃分析

植物入侵是全球环境变化的重要组成部分，可显著改变土壤生物群落——后者对于陆地生态系统中的有机质分解与养分循环至关重要。然而，入侵植物、土壤生物群落与酶活性之间的具体关联仍不明确。本研究基于107项研究中的688组配对观测数据开展了全面的荟萃分析（meta-analysis），以评估植物入侵对土壤生物群落、酶活性及养分循环的影响。

研究结果显示，植物入侵显著降低了草食动物（45%）、腐食动物（27%）与杂食动物（45%）的丰度；而异感作用、木本入侵植物与森林生态系统则分别使捕食者丰度降低47%、46%与32%。入侵植物还小幅降低了细菌与真菌生物量，但显著提升了丛枝菌根真菌（arbuscular mycorrhizal fungal, AMF）生物量、微生物生物量碳（MBC）与微生物生物量氮（MBN），分别提升29%、19%与32%。此外，入侵植物对……

本研究通过Web of Science与Google Scholar检索同行评审期刊论文，并按照系统综述与荟萃分析优先报告条目（Preferred Reporting Items for Systematic Review and Meta-analysis, PRISMA）流程对检索到的记录进行筛选。纳入满足以下标准的原始研究：（1）明确描述入侵植物与本土植物的种类，且开展了野外观测或受控实验；（2）采用磷脂脂肪酸法（PLFA method，Kong等，2011）同步测定了至少一类土壤功能类群、微生物群落组成或酶活性；（3）入侵样地与对照样地/本土植物样地处于相同的生物与非生物环境条件下；（4）所选变量的均值与样本量可从相关文献中获取或计算得到。本荟萃分析仅纳入土壤微生物群落组成与结构、土壤微生物生物量及其酶……

[本研究数据集支持植物入侵对土壤生物功能类群及微生物活性的影响相关研究。](https://doi.org/10.5061/dryad.hhmgqnkq5) 数据集包含作者姓名与发表年份、入侵物种、本土植物物种、生长型、异感作用特性与生态系统类型。此外还包含入侵组与对照组的响应变量数据（含均值、标准差与样本量）、地理坐标、所在大洲与国家。本研究针对土壤生物功能类群、微生物活性与养分循环开展荟萃分析，以量化植物入侵对各响应变量的效应量。
