Table 1; Summary results of univariate linear models showing
the relationships between available resources (net primary
productivity), annual mean precipitation, annual mean temperature,
temperature seasonality or precipitation seasonality with altitudes.
Table 2; Results for pairwise contrasts of the linear model
with log-transformed lizard body size (n = 432) and altitudinal
gradients (low altitudes: <1,000m; mid altitudes: 1,000–2,000
m; high altitudes: >2,000 m asl). Reported degrees of
freedom is for t statistics.
Table 3; Statistical parameters from linear mixed-effects
models of body size patterns with seasonally available resources across
different altitudes accounting for lizards’ population origins. Results
presented are for the model with resource availability (net primary
productivity), seasonality (temperature seasonality and precipitation
seasonality), altitudes and the interaction between resource
availability with altitudes as predictors.
Table 4; Statistical
parameters from linear mixed-effects models of body size patterns with
environmental conditions across different altitudes accounting for
lizards’ population origins. Results presented are for the model with
climatic conditions (annual mean temperature and annual mean
precipitation), seasonality (temperature seasonality and precipitation
seasonality), altitudes and the interaction between resource
availability with altitudes as predictors
Figure 1; Map showing
altitudinal gradients and collection sites of female Eremias
argus lizards from different altitudes across China. Color gradients
represent China’s altitudinal gradients in square meters, with colored
points depicting the geographical locations across China occupied by
female lizards in our study
Figure 2; Relationship
between log-transformed body size of lizards with altitudinal clines
across populations of lizards. Predicted values ± 1 SE of estimates from
the linear regression model (n = 432) that account for population
origins of lizards are shown by the connected dots.
Figure 3; The relationship between log-transformed lizard body
size with (a) net primary productivity and seasonal precipitation along
altitudinal clines; (b) net primary productivity and changes in seasonal
temperature along altitudinal clines. Color gradient of points
represents the changes in the pattern of log-transformed body size of
lizards with seasonally available resources at different altitudes.
Color gradient trendlines represent predicted values ± 1 SE of estimates
from the linear regression model (n = 432 ) that accounts for the
population origins of lizards. Separate coloured trendlines illustrate
significant (P < 0.05) relationships between lizard
body size seasonal available resources while single trendlines
illustrate non-significant relationships between lizard body size
seasonal available resources along altitudinal clines.
Figure 4; Relationship between lizard body sizes with a) annual
mean temperature, b) annual mean precipitation, c) precipitation
seasonality and d) temperature seasonality at different altitudes. Color
gradient of points represents the changes in the pattern of
log-transformed body size of lizards with climatic conditions at
different altitudes. Color gradient trendlines represent predicted
values ± 1 SE of estimates from the linear regression model (n =
432 ) that accounts for the population origins of lizards. Separate
colored trendlines illustrate significant (P < 0.05)relationships between lizard body size with climatic conditions along
altitudinal clines.
