Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Studies on Inter-and Intra-specific Competitions among The Seedlings of Spartina alterniflora and Kandelia obovata Grown under Different Nitrogen Nutritions [PDF]
, 2010 互花米草作为我国海岸盐沼入侵植物，对生长在热带、亚热带海岸潮间带的红树植物造成了较严重影响。而当今人类活动造成的氮资源增加能改变物种的竞争关系、促进高生长速率外来种的入侵。本文采用取代实验设计（ReplacementSeriesExperiments），研究了入侵植物互花米草和本地红树植物秋茄分别在单种种植和混合种植、可控氮浓度（CK-0、2.5、5、7.5和10mmol•L-1）条件下的生长和光合生理反应，从植物竞争影响和竞争反应方面来探讨互花米草和秋茄分别对竞争的抵御能力和竞争效应 ...

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.

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 ...
