Leaf Photosynthetic and Functional Traits of Grassland Dominant Species in Response to Nutrient Addition on the Chinese Loess Plateau

Plants, 2022
Leaf photosynthetic and functional traits of dominant species are important for understanding grassland community dynamics under imbalanced nitrogen (N) and phosphorus (P) inputs. Here, the effects of N (N0, N50, and N100, corresponding to 0, 50, and 100

Dental Erosion [PDF]

Polish Journal of Public Health, 2014
Dental erosion is described as an irreversible loss of dental hard tissue resulting from exposure to non-bacterial acids or chelating substances. It may be caused by exogenous or endogenous factors. In the former case, food, drink, as well as the environment might be sources of acids; in the latter, acids flowing into the oral cavity from the stomach ...

Overgrazing depresses soil carbon stock through changing plant diversity in temperate grassland of the Loess Plateau

Plant, Soil and Environment, 2018
This study mainly estimates the effect of grazing on plant diversity and soil storages on the northern Loess Plateau of China. Four grazing intensities of ungrazed (UG), light (LG), moderate (MG), and heavy (HG) grassland were selected according to the ...
