Fig. 4: Estimated demographic parameters across functional groups.
From: Linking functional traits and demography to model species-rich communities
Minimum tolerated temperature (a), sensitivity to biomass rate (b) and intraspecific competition rate (c) were estimated from the median of the posterior distribution of the parameters. Functional groups were forbs (76 species), grasses (26 species), legumes (11 species) and shrubs (5 species). Boxplots indicate the median, first and third quartiles of each distribution. Whiskers represent the minimum and maximum values that remain inferior 1.5 times the interquartile range below or above the distribution median. Anova tests indicate that all three demographic parameters were significantly different among functional groups (θmin: F = 2.742, p = 0.047; l F = 3.719, p = 0.013; c F = 4.669, p = 0.004). Uppercase letters above the boxplots symbolize the results of pairwise t-tests on demographic parameters among functional groups. Distinct letters characterize significantly different demographic parameter distributions among functional groups (p value ≤ 0.05 after adjustment by Holm’s correction). Note that min. tol. Temperature is relative to a mean annual temperature standardized across the study sites and is therefore unit-less.
