AI Article Synopsis
- The legacy effects of invasive plant species can obstruct the recovery of native ecosystems, particularly under conditions of nitrogen deposition, which favors the growth of invasives and can lead to further invasions.
- The study hypothesizes that nitrogen deposition exacerbates these legacy effects, exploring mechanisms related to community structure, nitrogen metabolism, geochemical cycles, and microbial interactions.
- Findings indicate that microorganisms, particularly nitrogen-fixing bacteria, play a crucial role in this process, influencing plant-soil feedback and offering insights for managing invasive species and enhancing ecosystem recovery.
Article Abstract
The legacy effects of invasive plant species can hinder the recovery of native communities, especially under nitrogen deposition conditions, where invasive species show growth advantages and trigger secondary invasions in controlled areas. Therefore, it is crucial to thoroughly investigate the effects of nitrogen deposition on the legacy effects of plant invasions and their mechanisms. The hypotheses of this study are as follows: (1) Nitrogen deposition amplifies the legacy effects of plant invasion. This phenomenon was investigated by analysing four potential mechanisms covering community system structure, nitrogen metabolism, geochemical cycles, and microbial mechanisms. The results suggest that microorganisms drive plant-soil feedback processes, even regulating or limiting other factors. (2) The impact of nitrogen deposition on the legacy effects of plant invasions may be intensified primarily through enhanced nitrogen metabolism via microbial anaerobes bacteria. Essential insights into invasion ecology and ecological management have been provided by analysing how nitrogen-fixing bacteria improve nitrogen metabolism and establish sustainable methods for controlling invasive plant species. This in-depth study contributes to our better understanding of the lasting effects of plant invasions on ecosystems and provides valuable guidance for future ecological management.

Non-layered 2D materials offer unique and more advantageous physicochemical properties than those of conventional 2D layered materials. However, the isotropic chemical bonding nature of non-layered materials hinders their lateral growth, making the synthesis of large-area continuous thin films challenging. Herein, a facile kinetically tailored chemical vapor deposition (KT-CVD) approach is introduced for the synthesis of 2D molybdenum nitride (MoN), a representative non-layered material.

Introduction: This study aims to explore the contribution of neutrophil extracellular traps (NETs) to kidney stones.
Methods: The microarray data from GSE73680 and bioinformatic analysis were applied to identify differentially expressed genes in patients with kidney stones. A rat model of kidney stones was established through ethylene glycol and ammonium chloride administration.

Background: Legumes, in the initial event of symbiosis, secrete flavonoids into the rhizosphere to attract rhizobia. This study was conducted to investigate the relationship between crop root exudates and soybean nodule development under intercropping patterns.
Method: A two years field experiments was carried out and combined with pot experiments to quantify the effects of planting mode, i.

Critical loads (CLs) are frequently used to quantify terrestrial ecosystem impacts from nitrogen (N) deposition using ecological responses such as the growth and mortality of tree species. Typically, CLs are reported as a single value, with uncertainty, for an indicator across a species' entire range. Mediating factors such as climate and soil conditions can influence species' sensitivity to N, but the magnitudes of these effects are rarely calculated explicitly.

Mangrove ecosystems, a type of blue carbon ecosystems (BCEs), are vital to the global carbon cycle. However, the combined effects of microplastics (MPs) and plastic additives on carbon sequestration (CS) in mangroves remain unclear. Here, we comprehensively review the sources, occurrence, and environmental behaviors of MPs and representative plastic additives in mangrove ecosystems, including flame retardants, such as polybrominated diphenyl ethers (PBDEs), and plasticizers, such as phthalate esters (PAEs).
