Functional Ecology, Volume 40, Issue 7, Page 2332-2344, July 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric ratios of carbon (C), nitrogen (N) and phosphorus (P) serve as important indicators for assessing nutrient balance in forest ecosystems, but their relationships with photosynthetic dynamics require deeper characterization.

Journal of Animal Ecology, Volume 95, Issue 7, Page 1178-1193, July 2026.This population‐comparative study reveals that male and female parents respond differently to social and ecological conditions. This sex‐specific responsive strategy is related to the incongruent parental care systems across populations in Chinese penduline tits.

Zhejiang Daxue xuebao. Lixue ban, 2005 采用膨胀颗粒污泥床(EGSB)处理涤纶仿真丝绸印染废水，通过污泥负荷和水力负荷的递增来启动反应器，从活性污泥性状和反应器性能两方面考察启动过程.活性污泥依次经历絮状、膨胀、细粒化和成熟颗粒四个阶段，反应器性能与此相应变化，有机物去除率和产气率逐渐提高且趋于稳定.结果表明，EGSB处理涤纶仿真丝绸印染废水的启动过程用了 50 d左右，启动后形成的颗粒污泥床层占反应器有效容积的25% 和污泥量的65% 左右，COD去除率为57% ~64%，产气率为0.12~0.17 m3 • (kgCOD)-1 ...

Global Change Biology, Volume 32, Issue 7, July 2026.Grassland recovery following nutrient cessation is asymmetric and strongly shaped by nutrient enrichment history. Higher nutrient addition rates and longer enrichment duration caused larger departures from control conditions, with biomass recovering more rapidly than species richness over decadal timescales.

Gongye shui chuli, 2007 从筛选到的絮凝剂产生菌中构建出比单一菌群产生更高活性絮凝剂的复合菌群——复合1(BAFRT4+CYGS1)。为降低培养成本,接种复合1至啤酒废水培养基中,产生了絮凝活性为96.8%的微生物絮凝剂(MBF)。所产MBF对靛蓝印染废水有良好的处理效果,CODCr去除率和脱色率最高分别达79.2%和87.6%。研究了复合1所产MBF在优化工艺条件下处理靛蓝印染废水的絮凝过程,并得出了MBF去除CODCr和脱色的经验动力学方程。
