Plant functional trait dissimilarity drives plant mixture effects on fine root biomass and trait variations. [PDF]
New PhytolSummary 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.

Shuitu Baochi Xuebao, 2001 以莫莫格湿地为研究对象 ,研究了氮磷在湿地土壤中的空间分布。结果表明 ,表层土壤全氮、全磷含量显著高于下层土壤 ,土壤全氮的水平变异性较全磷强 ;全氮和全磷的垂直分布总体变化趋势均为由上到下依次减少 ,且都以 5 0 cm处为其变化转折点 ,但全氮的变化较全磷快 ;全磷、全氮含量与土壤有机质、N/ P比极显著相关 ,但p H值对其影响十分微弱。

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.
