Signaling defenses with color: a meta‐analysis of leaf color variation, palatability, and herbivore damage

open access: yesNew Phytologist, Volume 247, Issue 2, Page 884-896, July 2025.
Summary We investigated the impact of leaf color variation on herbivory, testing current hypotheses indicating that leaf color could influence herbivory through bottom‐up control (by signaling leaf quality and defenses) or top‐down control (by attracting predators).
