A warming climate combined with frequent and severe fires cause permafrost to thaw, especially in the region of discontinuous permafrost, where soil temperatures may only be a few degrees below 0 °C. Soil thaw releases carbon (C) and nitro...
Seasonality of nitrogen balances in a Mediterranean climate watershed, Oregon, US [0.03%]
美国俄勒冈州地中海气候流域的氮平衡的季节变化规律性分析

We constructed a seasonal nitrogen (N) budget for the year 2008 in the Calapooia River Watershed (CRW), an agriculturally dominated tributary of the Willamette River (Oregon, U.S.) under Mediterranean climate. Synthetic fertilizer applicati...
Neotropical ostracode oxygen and carbon isotope signatures: implications for calcification conditions [0.03%]
新热带介形虫氧同位素和碳同位素特征：对钙化条件的启示
Claudia Wrozyna,Juliane Meyer,Martin Dietzel et al.
Claudia Wrozyna et al.
Calcitic valves of non-marine ostracodes are important geochemical archives. Investigations of the relationship between the ranges of oxygen and carbon isotope values of modern ostracode populations and their host water provide important in...
Soil phosphorus status and P nutrition strategies of European beech forests on carbonate compared to silicate parent material [0.03%]
碳酸盐和硅酸盐母质欧洲山毛榉林的土壤磷状况及其营养对策
Jörg Prietzel,Jaane Krüger,Klaus Kaiser et al.
Jörg Prietzel et al.
Sustainable forest management requires understanding of ecosystem phosphorus (P) cycling. Lang et al. (2017) [Biogeochemistry, https://doi.org/10.1007/s10533-017-0375-0] introduced the concept of P-acquiring vs. P-recycling nutrition strate...

Geochemical indicators are emerging as important predictors of soil organic carbon (SOC) dynamics, but evidence concerning the role of calcium (Ca) is scarce. This study investigates the role of Ca prevalence in SOC accumulation by comparin...
A holistic framework integrating plant-microbe-mineral regulation of soil bioavailable nitrogen [0.03%]
整合植物-微生物-矿物调节土壤生物有效氮的综合框架
Amanda B Daly,Andrea Jilling,Timothy M Bowles et al.
Amanda B Daly et al.
Soil organic nitrogen (N) is a critical resource for plants and microbes, but the processes that govern its cycle are not well-described. To promote a holistic understanding of soil N dynamics, we need an integrated model that links soil or...
Soil organic matter turnover rates increase to match increased inputs in grazed grasslands [0.03%]
放牧草地的土壤有机质周转率增加以匹配增加的输入量
Shane W Stoner,Alison M Hoyt,Susan Trumbore et al.
Shane W Stoner et al.
Managed grasslands have the potential to store carbon (C) and partially mitigate climate change. However, it remains difficult to predict potential C storage under a given soil or management practice. To study C storage dynamics due to long...
Characterizing bioavailable phosphorus concentrations in an agricultural stream during hydrologic and streambed disturbances [0.03%]
水文和河床扰动下农业河流中有效磷浓度的变化特征分析
Matt T Trentman,Jennifer L Tank,Heather A M Shepherd et al.
Matt T Trentman et al.
In freshwater ecosystems, phosphorus (P) is often considered a growth-limiting nutrient. The use of fertilizers on agricultural fields has led to runoff-driven increases in P availability in streams, and the subsequent eutrophication of dow...
From hogs to HABs: impacts of industrial farming in the US on nitrogen and phosphorus and greenhouse gas pollution [0.03%]

Nutrient pollution and greenhouse gas emissions related to crop agriculture and confined animal feeding operations (CAFOs) in the US have changed substantially in recent years, in amounts and forms. This review is intended to provide a broa...
Biogeochemistry of "pristine" freshwater stream and lake systems in the western Canadian Arctic [0.03%]
加拿大西部北极地区原始淡水溪流和湖泊系统的生物地球化学属性
Joshua F Dean,Michael F Billett,Robert Baxter et al.
Joshua F Dean et al.
Climate change poses a substantial threat to the stability of the Arctic terrestrial carbon (C) pool as warmer air temperatures thaw permafrost and deepen the seasonally-thawed active layer of soils and sediments. Enhanced water flow throug...
