Whether general patterns of signal evolution can be explained by selection for signal efficacy (detectability) has yet to be established. To establish the importance of signal efficacy requires evidence that both signals and their detectability to receivers have evolved in response to habitat shifts in a predictable fashion. Here, we test whether habitat structure has predictable effects on the evolution of male and female display coloration in 21 lineages of African dwarf chameleon… 
Selection for Social Signalling Drives the Evolution of Chameleon Colour Change
TLDR
It is shown that evolutionary shifts in capacity for colour change in southern African dwarf chameleons (Bradypodion spp.) are associated with increasingly conspicuous signals used in male contests and courtship, supporting the view that transitory display traits should be under strong selection for signal detectability.
Rapid divergence of social signal coloration across the White Sands ecotone for three lizard species under strong natural selection
TLDR
Compared social signal coloration of three lizard species across a substrate colour ecotone in New Mexico, the magnitude and direction of change in coloration varied among taxa, and differences in hue and chroma accounted for more variation in social coloration than for dorsal coloration.
Invasive chameleons released from predation display more conspicuous colors
TLDR
It is shown that Jackson's chameleons inadvertently introduced from Kenya to Hawaii (Oahu), where there are no coevolved, native lizard predators, experienced pronounced character release of color signals, demonstrating that relaxed predation pressure can result in characterRelease of dynamic social signals in introduced species experiencing strong sexual selection.
The evolution of multi-component visual signals in darters (genus Etheostoma)
TLDR
Comparative methods used to examine patterns of evolution in multiple compo- nents of a complex courtship signal in darters support the hypothesis that different components of complex signals may be subject to distinct evolutionary pressures, and suggests that the combination of behavioral displays and morphology in communication may have a strong influence on patterns of signal evolution.
Habitat structure drives the evolution of aerial displays in birds
TLDR
A continent-wide phylogenetic comparative analysis found that aerial displays are seven times more likely to evolve in open habitats than in forests, likely as a result of physical properties that allow aerial displays to transmit more broadly inopen habitats.
Habitat light and dewlap color diversity in four species of Puerto Rican anoline lizards
TLDR
Examination of dewlap color in four closely related species of Anolis lizards that occupy habitats with different light conditions concluded that divergent selection for signal detectability does not, by itself, explain the evolution of deWlap color diversity.
Predation-associated modulation of movement-based signals by a Bahamian lizard
TLDR
It is found that male brown anoles dramatically decreased the amplitude of their head-bob displays in the presence of a predatory lizard, resulting in less conspicuous signals, which may be safer for the signaling individuals but also reduce the distance from which potential mates or competitors can detect them.
Sexual Dimorphism in Bite Performance Drives Morphological Variation in Chameleons
TLDR
Results indicate that both natural and sexual selection are acting within both habitat types, but to varying degrees, with sexual selection seems to be the predominant force within the closed-canopy habitats, which are more protected from aerial predators, enabling chameleons to invest more in ornamentation for communication.
Geographic variation in aggressive signalling behaviour of the Jacky dragon
TLDR
It is argued that display variation might be a consequence of behavioural plasticity and that, despite difference in genetic structure, morphology and behaviour, this species retains a cohesive communication system.
Color polymorphic lures target different visual channels in prey

TLDR
Modeling supported a distinct bias in the chromatic or achromatic contrast presented by spiders at the times when they caught prey, as opposed to all other times at which they may be viewed, suggesting that color polymorphism may be adaptively maintained by selection for conspicuousness within different visual channels in receivers.

The Evolution of Signal Design in Manakin Plumage Ornaments
TLDR
It is shown that plumage contrast against the background increases with sexual dichromatism in males but not females, suggesting that sexual selection has favored the evolution of male plumage ornaments that enhance signal efficacy.
Dark habitats and bright birds illustrate the role of the environment in species divergence
TLDR
This study shows that variation in the physical environment can cause species divergence, and this will occur whether perceptual systems are variable or relatively constant.

TLDR
It is shown that canopy and understory act as distinct selective regimes that strongly influence bird coloration, and the evolution of color patterns for all organisms living in contrasted light environments is of general interest.

Signals, Signal Conditions, and the Direction of Evolution
TLDR
Sensory systems, signals, signaling behavior, and habitat choice are evolutionarily coupled and should coevolve in predictable directions, determined by environmental biophysics, neurobiology, and the genetics of the suites of traits.

TLDR
Factors are discussed which influence the evolution of color pattern polymorphisms, sexual dimorphism and dichromism, and some color pattern elements may be closely linked to physiologically variable loci, which further affect the variation in color patterns.
