Summary

This study examines how nitrogen addition from human activities affects the dominant alpine grass Leymus secalinus in an alpine meadow on the Qinghai–Tibetan Plateau. Through a long-term field experiment, researchers measured various plant traits including leaf structure to understand how the plant adapts its growth strategies, water use, and resource competition in response to different nitrogen levels. The research highlights how increasing nitrogen deposition alters the adaptive strategies of this key species.

Human activities are increasing the amount of nitrogen that falls onto alpine grasslands, altering how plants grow, use water, and compete for resources.

In this study, we examined how the dominant alpine grass Leymus secalinus responds to different levels of nitrogen addition in an alpine meadow on the Qinghai–Tibetan Plateau.

Using a long-term field experiment, we measured a wide range of plant traits, including leaf structure.
