Phylogenetic conservation of soil bacterial responses to simulated global changes. [PDF]

open access: yes, 2020
Soil bacterial communities are altered by anthropogenic drivers such as climate change-related warming and fertilization. However, we lack a predictive understanding of how bacterial communities respond to such global changes.

Soil Phosphorus Fraction Characteristics in Different Alpine Grassland Types of the Qinghai–Tibet Plateau

open access: yesAgronomy
The alpine grassland ecosystem of the Tibetan Plateau is a vital base for animal husbandry and a key ecological security barrier in China. Phosphorus (P), an essential nutrient, is among the primary factors limiting grassland productivity.
