Stability response of alpine meadow communities to temperature and precipitation changes on the Northern Tibetan Plateau.

Biomass temporal stability plays a key role in maintaining sustainable ecosystem functions and services of grasslands, and climate change has exerted a profound impact on plant biomass. However, it remains unclear how the community biomass stability in alpine meadows responds to changes in some climate factors (e.g.

Effects of adding betaine on biological nitrogen and phosphorus removal from simulated pickled vegetables wastewater.

Laboratory-scale sequencing batch reactors (SBR) were used to examine the effects of adding dosage and ways of adding betaine on nitrogen and phosphorus removal from simulated pickled vegetables wastewater under two different concentrations of salt. The activated sludge was pre-acclimated in a salt environment prior to the experiment. Adding 0.
