2024-09-03Chromolaena odorata affects soil nitrogen transformations and competition by altering ammonia oxidation microorganismsThe invasion mechanism of alien plants is the key basis for preventing and controlling biological invasion. Invasive plants can improve the utilization efficiency of soil nutrients by altering soil microbial composition, and creating a favorable soil environment conducive to invasion. Therefore, it is important to understand how invasive plants ...Read More -
2024-08-28Genetic consequences of long generation time and semelparity in the “queen of the Andes” (Puya raimondii)Puya raimondii Harms (Bromeliaceae), also colloquially known as the ‘Queen of the Andes’, is an endemic species of Peru and Bolivia that occurs in often very isolated populations (Fig. 1). Its habitat ranges from 3,000 to 4,800 m above sea level (asl) in the Puna ecosystem. This long-lived semelparous plant is an iconic species in the high And...Read More -
2024-08-25The global fate of inorganic phosphorus fertilizers added to terrestrial ecosystemsChinese Academy of Sciences built a global database of the fate of Pi fertilizers[the percentage of Pi fertilizer taken up by plants,the percentage of Pi fertilizer stored in the soil,and the percentage of Pi fertilizer lost,]. Phosphorus (P) is essential for the growth, functioning, and reproduction of all life on Earth. To meet the increasing demand for food and wood production, the global annual inorganic P (Pi) fertilizer consumption has increased from 5.0 Tg (1 Tg = 1012 g) in 1961 to approximately 25 Tg in 2020, and is expected to reach 27 Tg in 2050. Phosphorus ...Read More -
2024-08-20Atmospheric nitrogen deposition changes silicon cycle in subtropical forestSilicon (Si) is the second−most−abundant element in the earth's crust, which facilitates plant growth and defense and is closely associated with the carbon (C) cycle of terrestrial ecosystems. The absorption and utilization of Si by plants affect the biogeochemical cycle of Si and its coupling with C cycle. However, potential mechanisms by whi...Read More -

2024-07-27South China Botanical Garden reveals the mechanism of forest types regulating soil organic carbon compounds in response to exogenous phosphorus additionTropical forests are sensitive to exogenous nutrient input. The relative availability of phosphorus (P) compared to nitrogen (N) thus plays a vital role in tropical carbon (C) budget, yet how nutrient availability regulates the conversion between sink and source in tropical forest soil organic carbon (SOC) remains uncertain. Through the biochemi...Read More -
