Below are downloads for all image files used by Royer et al. (2008). The total size of the individual image files for each species is noted. For the Quercus kelloggii files, each number (001 to 154) represents a different tree, and each letter represents a different leaf on that tree. For the Acer rubrum files, in most cases all leaves from a single site are contained in a single file; exceptions to this have the suffix "#[number]". See "Other supplementary information" below for physiognomic and environmental information about all leaves. All images are completely unprocessed and in .TIF (Q. kelloggii) or .NEF (A. rubrum) format; all images require some sharpening and contrast adjustment. Scale bar units = 1 cm.
You are welcome to use these images and data for your own research. We only ask that you let us know and acknowledge us in any resulting publications. Processed images, which include clean backgrounds and tooth selection, are available upon request. Reproduction of the images posted here is prohibited for commercial use.
