High nitrogen enrichment buffers plant photosynthesis against herbivory damage
Functional Ecology, Volume 40, Issue 1, Page 229-238, January 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivorous insects and nitrogen deposition are key drivers of ecosystem productivity under global change. However, their combined effects on plant photosynthesis, particularly during insect outbreaks, remain poorly understood in natural ecosystems.

New Phytologist, Volume 249, Issue 2, Page 764-776, January 2026.Summary Fine roots are critical for soil resource uptake, yet how declining plant diversity alters fine root biomass (RB) and traits remains unclear. We tested how plant functional trait dissimilarity in shade tolerance, drought tolerance, growth rate, and nitrogen‐fixation ability drives variation in root attributes.

Review of Policy Research, Volume 42, Issue 6, Page 1496-1508, November 2025.ABSTRACT This study adopts a policy‐centric perspective to explore the complex relationship between sustainable nitrogen management (SNM) and the health risks associated with unsafe drinking water. The critical policy challenge lies in balancing the essential role of nitrogen fertilizers in achieving high agricultural productivity with their ...

Trait‐Mediated Competition for Light Underpins Plant Diversity Loss Under Eutrophication
Global Change Biology, Volume 31, Issue 9, September 2025.Eutrophication often reduces plant diversity by making the ground layer darker, which reduces understory plants. In a natural alpine grassland, we added LED light beneath the canopy and saw diversity return across different nutrient treatments: with added nitrogen fertilizer, light mainly increased new species; with added phosphorus fertilizer, it ...

, 2021 于2018年在晋北典型农牧交错带盐碱化草地设置增减降水和氮添加处理试验,2019年生长季(5—9月)采用原位顶盖PVC埋管法测定不同水、氮处理下土壤净氮矿化速率,研究盐碱化草地土壤净氮矿化速率对降水格局变化和氮沉降的响应。结果表明:土壤净氮矿化速率表现出明显的季节动态。单独增减降水(±50%)和氮添加(10 g·m~(-2)·a~(-1))以及氮添加+增加50%降水处理对土壤净氮矿化速率影响不显著,氮添加+减少50%降水处理显著提高土壤净硝化速率和净氮矿化速率,分别提高10.8和8.6倍 ...
