The underappreciated roles of fog and dew on vegetation and biocrusts

New Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

喀斯特峡谷区不同恢复阶段土壤微生物量及呼吸商

Shuitu Baochi Xuebao, 2011
土壤微生物生物量、土壤微生物呼吸及微生物商值(微生物商qMB、微生物呼吸商qCO2)是土壤质量的敏感性指标。对喀斯特峡谷区不同植被恢复阶段土壤微生物生物量、土壤微生物呼吸及其qMB、qCO2进行研究,结果表明:在植被恢复过程中,土壤微生物生物量、土壤微生物呼吸及qMB均表现为从退耕地到草本群落下降,从草本到灌木群落上升,从灌木到乔木群落略微上升或者趋于稳定;qCO2的变化规律与它们相反。在同一恢复阶段,土壤微生物生物量,土壤微生物呼吸,qMB值均随土层加深而减小。土壤微生物生物量、微生物呼吸及其qMB ...

Root exudates mediate microorganisms to improve rhizosphere nutrient availability and crop productivity under straw mulching and slow‐release nitrogen fertilizer

Functional Ecology, Volume 40, Issue 6, Page 1725-1739, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

施肥对金沙江干热河谷退化草地土壤微生物的影响

Shuitu Baochi Xuebao, 2005
在金沙江干热河谷区的退化草地上进行了2年的氮磷施肥试验,试验结束后分析了土壤特性及土壤微生物数量和生物量的变化。结果表明,在施氮量为5 ,15g/ (m2 ·a)时,土壤微生物的数量和生物量均没有明显变化,而当施氮量增加到2 5g/ (m2 ·a)时,土壤微生物的数量和生物量比对照明显增加。施磷没有引起土壤微生物数量和生物量的明显增加。施氮和施磷均没有引起土壤细菌、真菌和放线菌组成的变化。这表明氮虽然影响土壤微生物的数量,但对土壤微生物的组成没有影响。施氮导致土壤硝态氮增加,但对氨态氮影响不大 ...

Sustainable Nanocellulose‐Based Materials for Environmental Remediation: Structure–Function Relationships and Applications

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Environmental pollution across water, air, and soil systems poses escalating threats to human health and ecosystem stability, driven by heavy metals, persistent organic pollutants, particulate matter (PM), bioaerosols, and toxic gases. Conventional remediation technologies often suffer from limited selectivity, insufficient efficiency, and the

冰灾后城市森林不同恢复类型土壤微生物特性及其对土壤因子的响应

Shuitu Baochi Xuebao, 2011
为探究冰灾后城市森林不同植被恢复类型土壤微生物的演变特征,对长沙天际岭林场冰灾后3种恢复植被的栾树人工纯林、蕨草地、针阔混交林冬夏两季的土壤微生物数量、微生物活度、土壤理化性质及其相互关系进行了比较研究.结果表明,夏初不同植被恢复类型0-15 cm土层土壤微生物活度以针阔混交林最高(0.302),蕨草地次之(0.261),栾树人工纯林最低(0.192);3类植被中栾树人工纯林土壤冬季放线菌活力最弱,夏季细菌活力最弱;栾树人工纯林、针阔混交林土壤微生物生命活动冬季以真菌、细菌为主,夏季以真菌、放线菌为主 ...

Nitrogen deposition does not exacerbate phosphorus limitation of rhizosphere microbes in subalpine forests

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.

Wildfire strengthens the relationship between soil biodiversity and ecosystem multifunctionality in subtropical forests

Functional Ecology, Volume 40, Issue 5, Page 1415-1427, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Wildfires are disrupting and regenerating forces in nature that affect all ecosystem components. However, the impact of wildfires on soil multitrophic biodiversity and the resulting consequences for ecosystem multifunctionality (EMF) remain poorly understood.

Elevation, soil pH and calcium availability shape regional and local scale spatial patterns of PhoD gene abundance in tropical and subtropical forests

Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.
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.
