Exposure to cadmium (Cd), a toxic heavy metal classified as a group 1 carcinogen can lead to cancer, osteoporosis and renal disorder.
　　Contamination of soil with Cd results in human dietary intake from plant-derived food, with rice as the major source of dietary Cd for nearly half of the ...

　　Urbanization, the migration of populations from rural to urban areas, has been causing great stress on natural environments, leading to air pollution and nitrogen (N) deposition, negatively affecting forest health. Although there is evidence that urbanization has changed forest N cycling, li...

　　Biological nitrogen (N) fixation (BNF), an important source of N in terrestrial ecosystems, plays a critical role in terrestrial nutrient cycling and net primary productivity. Currently, large uncertainty exists regarding how nutrient availability regulates terrestrial BNF and the drivers re...

　　The limiting factor of tree growth in subtropical regions of China has not been conclusive. Numerous studies have shown that climate is not the primarily limit factor of tree growth. Therefore, it is widely speculated that competition may play a vital role, but there is no relevant report at...

　　Forest conversion to agriculture has recently been found to result in a substantial decrease in microbial nitrate (NO3-) assimilation in soil, which is a key cause of NO3- accumulation and thus increases the risk of nitrogen losses from agricultural soils.
　　However, how and why the respec...
