Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

Rare Metals, EarlyView.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Rare Metals, EarlyView.ABSTRACT Rare earth elements (REEs) play an irreplaceable role in modern technology and industry. However, due to the highly similar physicochemical properties among REEs, their separation remains a significant challenge. Additionally, REEs often exist in low‐concentration solutions, making efficient REE recovery an urgent task.

Rare Metals, EarlyView.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

Shuitu Baochi Xuebao, 2006 大田试验研究了保护性耕作对土壤微生物量、活跃微生物量、土壤呼吸、呼吸商、土壤酶的影响。结果表明，秸秆还田能够显著提高土壤微生物量碳和活跃微生物量，深松耕还田能显著提高土壤活跃微生物量。随耕作作业之后时间的推迟，活跃生物量减小。秸秆还田初期（小麦越冬期）能显著提高土壤呼吸作用，提高99．7％；后期（小麦播种期）能显著降低土壤呼吸，降低16．6％。随耕作作业之后时间的推迟，秸秆还田和保护性耕作都会减少农田向大气中CO2的排放，减少土壤碳库的亏损。深松耕还田显著提高土壤脲酶、蔗糖酶活性 ...
