Extended Data Fig. 4: The global biogeography of the proportion of annual herbs and the effects of yearly and quarterly climate patterns using a gridded system.
From: Revising the global biogeography of annual and perennial plants
A, The global proportion of annuals herbs in cells with sufficient data; cells with insufficient data (see Methods) are coloured grey resulting in 5,824 coloured cells. B, The distribution of annual herbs proportions among grid cells. C, A scatterplot of the effects of mean yearly precipitation and temperature (the outline of Whittaker’s biomes is marked by orange lines). D, Predictions of a regression model of the annual herbs proportion as a function of mean yearly temperature and precipitation (contour lines every 5%). E, A scatterplot of the effects of total precipitation and mean temperature of the warmest quarter. F, Predictions of a regression model of the annual herbs proportions as a function of total precipitation and mean temperature of the warmest quarter (contour lines every 5%). N = 5,824. G, A sample of how enlarged grid cells (150 km × 150 km) omit islands/coastal regions.
