Leaf colour change is commonly observed in temperate deciduous forests in autumn. This is
not simply a side effect of leaf senescence, and, in the past decade, several hypotheses …

In addition to providing pigmentation to facilitate plant reproduction, flavonoid and betalain
metabolites have important functions in plant tolerance to abiotic and biotic stresses …

Yellow and red autumn leaves are typical of many temperate/boreal woody plants. Since the
19th century, it has been either considered the non‐functional outcome of chlorophyll …

This book about various types of visual defense (coloration, morphology, movement) of
plants against herbivores is not just a list of facts and hypotheses, with a reference source …

Whether plants use leaf colour to deter herbivores remains controversial. The warning signal
hypothesis predicts that red pigmentation is adaptive by reducing herbivory; plants with …

Aposematic (warning) coloration is a common defense in plants, although it was largely
ignored before 2001. The fact that many aposematic animals use both plant-based pigments …

Instead of red anthocyanins, birches synthesise colourless (to human eye), UV-absorbing
flavonols during autumn senescence. To test if flavonols protect against insects, and if …

I review the hypotheses that have been proposed to explain the adaptive value of autumn
leaf colours. The available adaptive hypotheses can be reduced to the following …

Most innate responses to color stimuli lead herbivorous insects to orient to “green” and
“yellow” surfaces. Early research showed that aphid orientation to plants is influenced by …

Leaf margins of many plant species belonging to the floras of several continents feature a
conspicuous band of red/purple color around their periphery. Despite the widespread …
