X-Ray micro-tomography unveils the internal features of volcanic ash aggregates [0.03%]
X射线显微断层扫描揭示火山灰集合体的内部特征
Pietro Gabellini,Eduardo Rossi,Raffaello Cioni et al.
Pietro Gabellini et al.
Volcanic ash aggregation occurs during transport in the atmosphere when individual ash particles collide and stick together. It significantly impacts ash residence time in the atmosphere, with major consequences for hazard assessment and as...
Drivers of antimicrobial resistance in pig production systems of Uganda [0.03%]
乌干达猪生产系统中抗微生物药物耐药性产生的驱动因素

Increasing protein demand in low- and middle-income countries may accelerate livestock intensification, antibiotic overuse and antimicrobial resistance (AMR) risk. Here, we examined Uganda's growing pig sector, tracking 70 farmers and their...

Bioarchaeology not only provides insights into human, animal, and environmental ecology, but also generates huge amounts of stable and radiogenic isotope data that are not well recognised by other disciplines. Here, we present potential ave...
Fine root and soil carbon stocks are positively related in grasslands but not in forests [0.03%]
草地而并非森林中的细根与土壤碳储量之间的关系呈正相关
Avni Malhotra,Jessica A M Moore,Samantha Weintraub-Leff et al.
Avni Malhotra et al.
Increasing fine root carbon (FRC) inputs into soils has been proposed as a solution to increasing soil organic carbon (SOC). However, FRC inputs can also enhance SOC loss through priming. Here, we tested the broad-scale relationships betwee...
Foliar methane and nitrous oxide fluxes in Salix bebbiana respond to light and soil factors [0.03%]
光和土壤因素对Salix bebbiana叶片甲烷和氧化亚氮通量的影响

Foliar exchange of methane and nitrous oxide is a significant yet poorly understood component of global greenhouse gas budgets. To address this knowledge gap, we investigated foliar methane and nitrous oxide fluxes in Salix bebbiana, under ...
Sea ice controls net ocean uptake of carbon dioxide by regulating wintertime stratification [0.03%]
海冰通过调节冬季海洋层化控制海洋二氧化碳的净吸收作用
Elise S Droste,Dorothee C E Bakker,Hugh J Venables et al.
Elise S Droste et al.
Sea-air exchange of carbon dioxide in the Southern Ocean is strongly seasonal, with ocean uptake in summer, which is partly offset by carbon dioxide outgassing in winter. This seasonal balance can shift due to sea ice conditions, inducing i...
Stratospheric aerosol injection can weaken the carbon dioxide greenhouse effect [0.03%]
向平流层注入气溶胶可以削弱二氧化碳温室效应
Haozhe He,Brian J Soden,Gabriel A Vecchi et al.
Haozhe He et al.
Stratospheric aerosol injection is a proposed method for offsetting greenhouse gas-induced warming by introducing scattering aerosols into the lower stratosphere to reflect sunlight. Here we explore a potentially more efficient alternative:...
Satellite data indicates recent Arctic peatland expansion with warming [0.03%]
卫星数据显示近期北极泥炭地随着气候变暖而扩张
K A Crichton,K Anderson,R E Fewster et al.
K A Crichton et al.
Northern peatlands are an important carbon store in mid to high latitudes, but become increasingly discontinuous in the higher latitudes, associated with temperature and precipitation limits on plant growth. During the last four decades, me...
Battery electric vehicles show the lowest carbon footprints among passenger cars across 1.5-3.0 °C energy decarbonisation pathways [0.03%]
在1.5-3.0°C脱碳路径下，电动汽车的碳足迹最低
Joris Šimaitis,Rick Lupton,Christopher Vagg et al.
Joris Šimaitis et al.
Passenger car carbon footprints are highly sensitive to future energy systems, a factor often overlooked in life cycle assessment. We use a time-dependent prospective life cycle assessment to enhance carbon footprints under four 1.5-3.0 °C...
Prioritisation of ocean biodiversity data collection to deliver a sustainable ocean [0.03%]
优先开展海洋生物多样性数据采集工作 以实现可持续发展海洋目标

Fundamental ecological questions about the distribution of ocean life remain unanswered, hindering both the effective management of the ocean, and our comprehension of life on this planet. The benthic and pelagic realms are subject to diffe...
