Predicting microbially mediated plant coexistence is sensitive to vital rate identity and soil conditioning history

Understanding the mechanisms that maintain the coexistence of plant species is critical to addressing the global biodiversity crisis. Increasing attention has been paid to interactions between plants and soil microbes (plant-soil feedback, PSF), which can promote plant coexistence by increasing stabilizing effects, but also hinder it by generating competitive fitness differences. However, the predictive power of the PSF has been questioned in recent studies because estimates of microbially mediated coexistence have correlated poorly with the outcomes of plant interactions observed in the field. This discrepancy may be due to the approaches typically used in PSF research, such as measuring PSF effects on a single vital rate or using soil conditioned for a short time period and without considering abiotic contexts. Here, I examined the effects of soil inoculum with different training histories and training environments (with and without added nutrients) on germination, seedling survival, ..., , # Predicting microbially mediated plant coexistence is sensitive to vital rate identity and soil conditioning history

1. psf_vital.csv - Data from the test phase

Variables:

* pot_code
* ID_focal_sp = identity of species used in the test phase
* soil_history = conspecific training histories of soils used in the test phase: i) 'continuous' type, consisting of soil trained by conspecifics in two subsequent periods (June 2015-June 2019 and July 2019-April 2022); ii) 'recent' type, when the soil was trained by conspecifics in the second period (July 2019-April 2022) but by heterospecifics in the first one; iii) 'past' type, if the soil was train...,

解析维持植物物种共存的机制，对于应对全球生物多样性危机至关重要。当前学界愈发关注植物与土壤微生物间的互作（plant-soil feedback, PSF，植物-土壤反馈）——这类互作既可通过增强稳定效应促进植物共存，也可通过产生竞争性适合度差异阻碍共存。然而近年研究对植物-土壤反馈的预测能力提出了质疑：微生物介导的共存效应估算结果，与野外观测到的植物互作结局关联性较弱。这种偏差可能源于当前植物-土壤反馈研究常用的实验方法局限，例如仅测定微生物对单一生命率的影响，或是使用短期驯化的土壤，且未考虑非生物环境背景。本研究针对不同驯化历史与驯化环境（添加养分与不添加养分）的土壤接种物，探究其对植物萌发、幼苗存活……
