Frequent fire alters soil total phosphorus but does not affect phosphorus availability in a montane grassland [0.03%]
频繁的野火会改变亚高山草原土壤总磷含量但不会影响磷有效性
Nicola J Findlay,Guy Thibaud,Alan D Manson et al.
Nicola J Findlay et al.
Phosphorus (P) is often a limiting nutrient in highly weathered soils. Fire is a major driver of nutrient redistribution and can temporarily increase the pool of plant-available P in P-limited ecosystems. Yet, the long-term effects of frequ...
Iron and sulphur regulate carbon dioxide emissions in drained coastal peatlands of The Netherlands [0.03%]
铁和硫调节荷兰排水滨海泥炭地二氧化碳的排放
Duygu Tolunay,Gizem Ergut,Levi Simon et al.
Duygu Tolunay et al.
Fluctuating groundwater levels in drained peatlands create a transition zone with seasonally changing oxygen availability. This zone drives dynamic iron (Fe) and sulphur (S) cycling under alternating anoxic and oxic conditions, influencing ...
Organic acid concentration thresholds to mobilize phosphorus (P) in dryland soils [0.03%]
干旱地区土壤中有机酸浓度的提高对磷活化的影响阈值研究
Kalpana Kukreja,Elizabeth Noriega Landa,Wen-Yee Lee et al.
Kalpana Kukreja et al.
Available phosphorus (P) concentrations are low in dryland soils due to high pH values linked to the presence of pedogenic carbonates. Thus, dissolution and mobilization of P compounds are important controls on P availability for plants, mi...
Vegetation type influences particulate organic matter storage along a low Arctic vegetation gradient [0.03%]
植被类型影响低纬度北极植被梯度上的颗粒有机物储存
Lewis Sauerland,Rica Wegner,Andrei Moise et al.
Lewis Sauerland et al.
Permafrost soils constitute a large part of the terrestrial carbon pool that is vulnerable to future climate warming. Continued warming of the low Arctic is also leading to the encroachment of large shrubs and trees into tundra ecosystems w...
Temporal variability in dissolved organic matter composition export in streams [0.03%]

Export of dissolved organic carbon (DOC) from freshwater systems has been the focus of many studies owing to its pivotal role in regulating global carbon fluxes and ecosystem function. Both the flux and composition of dissolved organic matt...
Ocean surface waves impact on global air-sea CO [Formula: see text] flux [0.03%]
海浪对全球空气-海洋二氧化碳通量的影响

Ocean surface gravity waves facilitate gas exchanges primarily in two ways: (1) the formation of bubbles during wave breaking increases the surface area available for gas exchange, promoting CO 2 transfer, and (2) wave-current interactio...
Influence of temperature on selenium mobility under contrasting redox conditions: a sediment flow-through reactor experiment [0.03%]
温度对不同氧化还原条件下硒迁移的影响：沉积物流动反应器实验研究

Audrey Laberge-Carignan et al.
Selenium (Se) biogeochemistry in boreal and permafrost-rich soils and sediments remains poorly constrained, despite its importance as both an essential micronutrient and potential contaminant. As climate change accelerates warming in northe...
Ironing out the question: what is limiting cyanobacteria in freshwater lakes in the Prairie Pothole Region? [0.03%]
铁了心的问题：草原洼地地区淡水湖泊中蓝藻生长受限因素是什么？
Irena F Creed,Owen Salmon,Kevin J Erratt et al.
Irena F Creed et al.
The Canadian Prairie Pothole Region is a notable hotspot for cyanobacteria-dominated lakes. This study found minor variations in cyanobacterial genera across these lakes yet observed significant differences in standing biomass, as the lakes...
Springtime soil and tree stem greenhouse gas fluxes and the related soil microbiome pattern in a drained peatland forest [0.03%]
排水泥炭地森林中春季土壤和树干温室气体通量及其相关土壤微生物群落格局
Reti Ranniku,Fahad Ali Kazmi,Mikk Espenberg et al.
Reti Ranniku et al.
Spring can be a critical time of year for stem and soil methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) emissions as soil freeze-thaw events can be hot moments of gas release. Greenhouse gas fluxes from soil, Downy birch (Betula...
Global observation gaps of peatland greenhouse gas balances: needs and obstacles [0.03%]
