Abstract Animal signals are inherently complex phenotypes with many interacting parts combining to elicit responses from receivers. The pattern of interrelationships between signal components reflects the extent to which each component is expressed, and responds to selection, either in concert with or independently of others. Furthermore, many species have complex repertoires consisting of multiple signal types used in different contexts, and common morphological and physiological constraints…

Woodpecker drum evolution: An analysis of covariation in elements of a multicomponent acoustic display among and within species
The evolution of the woodpecker drum display is explored, finding evidence for strong coevolution of drum speed and length among species and within species, and in all cases of covariation at both evolutionary scales, the relationship between drumSpeed and length is positive, indicating mutual elaboration of display components and not a performance trade‐off.
Covariation among multimodal components in the courtship display of the túngara frog.
How multimodal components of a communication system relate to each other are demonstrated and provide an important foundation for future studies on how receivers integrate and compare complex displays.
Integration of intra- and inter-sexual selection signaling
The presence of an integrated syndrome demonstrates that intra- and intersexual signals are incorporated in a redundant signal strategy in Acheta domesticus, demonstrating one way in which classic hypotheses can be integrated with modern systems approaches.
Natural selection acting on integrated phenotypes: Covariance among functional leaf traits increases plant fitness.
It is suggested that the coordinated expression of leaf traits has an adaptive value, probably related to the optimization in the expression of traits related with water conservation and nitrogen acquisition.
Specificity of Male Responses to Female Vibratory Signals in two Chinavia Species (Hemiptera: Pentatomidae) is Based on Signal Structure and Narrow Temporal Parameters
The results confirm that specific elements of male vibratory signals are critical for female signal recognition and discrimination by males and could contribute to prezygotic isolation in sympatric Chinavia species.


Elaborate visual and acoustic signals evolve independently in a large, phenotypically diverse radiation of songbirds
It is found that elaborate visual and vocal sexual signals evolve independently among tanagers, although the relationship between song and plumage complexity varies among subfamilies.
Signal Design and Perception in Hypocnemis Antbirds: Evidence for Convergent Evolution Via Social Selection
Songs in both sexes elicit strong territorial responses within and between species, whereas songs of a third, allopatric and more closely related species are structurally divergent and elicit weaker responses, providing compelling evidence that social selection can act across species boundaries to drive convergent or parallel evolution in taxa competing for space and resources.
Multimodal signalling in the North American barn swallow: a phenotype network approach
This work integrates model testing with correlation-based phenotype networks to infer the contributions of female mate choice and male–male competition to the evolution of barn swallow communication, and interprets model results in the context of a network of traits.
Complex signal function: developing a framework of testable hypotheses
This work builds a framework of functional hypotheses of complex signal evolution based on content-driven (ultimate) and efficacy-driven selection pressures (sensu Guilford and Dawkins 1991), and point out key predictions for various hypotheses and discuss different approaches to uncovering complex signal function.
Multivariate Phenotypic Evolution: Divergent Acoustic Signals and Sexual Selection in Gryllus Field Crickets
A role for sexual selection in shaping patterns of phenotypic covariation that can ultimately affect the evolutionary trajectory of a multivariate mating signal is highlighted.

Experimental and correlative results indicate the need to incorporate the so far poorly considered role of phenotypic plasticity in the complex connection between environmental structure and individual call attributes of the frog Hypsiboas pulchellus.

Advertisement calls of closely related species often differ in quantitative features such as the repetition rate of signal units. These differences are important in species recognition. Current
Phenotypic integration: studying the ecology and evolution of complex phenotypes
It is suggested that studying integration provides a particularly stimulating and truly interdisciplinary convergence of researchers from fields as disparate as molecular genetics, developmental biology, evolutionary ecology, palaeontology and even philosophy of science.
Phenotypic covariance structure and its divergence for acoustic mate attraction signals among four cricket species
P was of full or almost full dimensionality in all four species, indicating that all traits conveyed some information that was independent of the other traits, and that phenotypic trait covariances do not constrain the combinations of signaling traits available to selection.
Phenotypic plasticity affects the response of a sexually selected trait to anthropogenic noise
It is shown that background noise is a considerable pressure in shaping a sexually selected multicomponent acoustic signal, bird song, and that plasticity integration between components may further restrict the elaboration of song.
