Core Insights - The research conducted by Lanzhou University reveals the impact of nitrogen enrichment on the stability of alpine meadow ecosystems in the Tibetan Plateau, highlighting the importance of plant phenology in understanding ecological stability under climate change scenarios [1][2] Group 1: Research Findings - Nitrogen enrichment negatively affects the temporal stability of plant community biomass in alpine meadows, while changes in precipitation do not have a significant impact [2] - The decline in temporal stability under nitrogen enrichment is not linked to the loss of species diversity but is determined by species asynchrony and the temporal stability of dominant functional groups, regulated by the phenology of alpine plants [2] Group 2: Methodology and Implications - The research team conducted a four-year observational study on 55 species of alpine meadow plants, focusing on leaf emergence and flowering phenology, to assess the effects of nitrogen enrichment and precipitation changes on community stability [1] - The findings provide critical scientific evidence for evaluating the impact of climate change on ecological safety in the Tibetan Plateau, offering new perspectives for the protection of alpine meadow ecosystems [2]
