Physiological Responses of Dominant Alpine Plant Species to Environmental Gradients on the Tibetan Plateau.

Poa litwinowiana ( Figure 3 c) showed the strongest structural correlation with meteorological variables, indicating that it was the most sensitive to temperature changes; Carex moorcroftii ( Figure 3 b) showed a weaker relationship with environmental gradients at the level of population indicators, showing a certain degree of conservatism in environmental adaptations; Carex parvula ( Figure 3 a) showed highly significant structural correlations with meteorological variables in several key physiological indicators, reflecting that it had stronger integration and regulation of its physiological pathways along environmental gradients.
