Extended Data Fig. 1: Frequency distributions of data for survey plots, climate, and plant species.
From: Contrasting thermophilization among forests, grasslands and alpine summits
a, Frequency distribution of plot at baseline and resurvey years in forest, grasslands, and alpine summits. b, Frequency distribution of growing season (April to September) mean temperature (Tmean) change rate across the duration of plant surveys in forests, grassland, and alpine summits. The rate of Tmean change for each plot was calculated as the difference between the average mean temperature during the 5 years preceding the baseline survey and the resurvey, divided by the time interval between the two surveys. The medians of the growing season Tmean change rate across forests, grasslands, and alpine summits were 0.31, 0.22, and 0.31 °C per decade, respectively. c, Frequency distribution of the number of grid cells representing species range sizes quantified by area of occupancy (AOO). Across the species pool in our study, 36.4% of the species have AOO < 1000, among which 77.5% of the species have AOO < 500. The green and blue dashed line indicate an AOO of 500 and 1000, respectively.
