Fig. 4: Partial response plots of climate variables used in species distribution modeling for Cochemiea halei . The plots show the marginal response of C. halei to each variable. The variables are (a): annual temperature range, “Trng”, (b): average temperature of the warmest quarter, “Awarm”, (c): precipitation of the warmest quarter, “Pwarm”, and (d): precipitation of the coldest quarter. The y -axis for each plot is on a logit scale, showing the relative impact of values of the variable on the probability of occurrence. The x -axis for the temperature variables, (a) and (b), is in degrees C. Precipitation variables, (c) and (d), are in mm. The x -axis is marked with a decile rug plot.
