We lack an adaptive explanation for a striking phenomenon, that of bright colours displayed in autumn by the leaves of many deciduous trees. The usual explanation is that it is simply a non-adaptive secondary effect of leaf senescence. A game-theoretic model of biological signalling provides an adaptive hypothesis for autumn colours showing that they can be the result of a process of coevolution between insects and trees: if leaf colour acts as a warning indicator of the tree's vigour to autumn…

The coevolution theory of autumn colours

This work tries to clarify what the coevolution theory of autumn colours actually says and to correct some misunderstandings that have been put forward, and reviews current research on autumn colours.

A test of the coevolution theory of autumn colours: colour preference of Rhopalosiphum padi on Prunus padus

Observed colonization of the aphid Rhopalosiphum padi on individual tress of Prunus padus in autumn and observed a strong preference of aphids for trees with green leaves, the first direct observation of a key assumption of the coevolution theory, that parasites avoid bright colours.

Evidence from the domestication of apple for the maintenance of autumn colours by coevolution

It is shown that aphids avoid apple trees with red leaves in autumn and that their fitness in spring is lower on these trees, which suggests that red leaves are an honest signal of the quality of the tree as a host.

The adaptive significance of autumn leaf colours

It is argued that the principal assumptions of the theory that autumnal leaf colours were signals produced by the trees to warn potential insect herbivores of their defensive ability do not match current knowledge of plant pigment biochemistry and aphid ecology.

Coevolution and the adaptive value of autumn tree colours: colour preference and growth rates of a southern beech aphid

It is suggested that aphid preference for green might have evolved to exploit better their host during the autumn rather than to improve their performance in spring.

A field study with geometrid moths to test the coevolution hypothesis of red autumn colours in deciduous trees

The results clearly showed that anthocyanin concentration was not correlated with the growth performance of the moths in any of the studied tree species, and this study does not support the coevolution hypothesis of autumn colours.

Importance of olfactory and visual signals of autumn leaves in the coevolution of aphids and trees.

The indirect defence hypothesis is presented to explain low aphid diversity on tree species that are green during autumn and suggests that green foliage can continue to produce herbivore-inducible plant volatiles and maintain volatile-based indirect plant defences against aphids until leaf abscission.

Classification of hypotheses on the evolution of autumn colours

I review the hypotheses that have been proposed to explain the adaptive value of autumn leaf colours and defines assumptions and predictions, and discusses briefly conceptual problems and available evidence.

Fruit Flags: Two Hypotheses

The two hypotheses presented here illustrate how fruit flags may increase conspicuousness of fruiting species thereby increasing visitation by frugivorous birds and creating a long-distance signal for bird-dispersed seeds.

Differential colonization of resistant and susceptible host plants: Pemphigus and Populus.

The ability of colonizers to select appropriate hosts when colonization occurs long before feeding, and when traits available as cues may be least associated with host quality is examined.

Leaf-mining insects and fluctuating asymmetry in elm Ulmus glabra leaves

Developmental stability of leaves, as measured by fluctuating asymmetry, was associated with susceptibility to one kind of herbivory in elm trees, and appeared to be causal since increased asymmetry caused by the fertilizer treatment gave rise to an increased abundance of leaf miners.

Direct and indirect effects of plant genetic variation on enemy impact

A positive correlation between survival of Phyllonorycter and Phyllocolpa eleanorae and parasitism of these species were negatively correlated with densities of the same heterospecific herbivores among clones may suggest either facilitation of survival between herbivore species, or an apparent interaction caused by host plant genetic variation.

Quantitative Investigations of Leaf Pigments From Their Inception in Buds Through Autumn Coloration to Decomposition in Falling Leaves

Pigments in hazel, aspen, and pin oak leaves were measured from their inception in buds to development of a summer maximum, and through the autumn coloration period to decomposition in dry falling leaves, discussing the usefulness of chlorophyll content as an index of net primary productivity.

Evolution and the Theory of Games

It is beginning to become clear that a range of problems in evolution theory can most appropriately be attacked by a modification of the theory of games, a branch of mathematics first formulated by Von Neumann and Morgenstern in 1944 for the analysis of human conflicts.
