“…Acoustic communication in crickets shows widespread (i) behavioral coupling, where male and female traits are matched within species; (ii) temperature coupling, where cooler males produce slower songs that are preferred by cooler females (5); and (iii) developmental coupling where males reared at cool temperatures sing slower songs that are preferred by females reared at equally cooler temperatures (30)(31)(32). Several authors have hypothesized mechanisms for both the physiological and genetic bases of behavioral coupling (3,5,6,33).…”

The genetic coupling hypothesis of signal-preference evolution, whereby the same genes control male signal and female preference for that signal, was first inspired by the evolution of cricket acoustic communication nearly 50 years ago. To examine this hypothesis, we compared the genomic location of quantitative trait loci (QTL) underlying male song and female acoustic preference variation in the Hawaiian cricket genus Laupala. We document a QTL underlying female acoustic preference variation between 2 closely related species (Laupala kohalensis and Laupala paranigra). This preference QTL colocalizes with a song QTL identified previously, providing compelling evidence for a genomic linkage of the genes underlying these traits. We show that both song and preference QTL make small to moderate contributions to the behavioral difference between species, suggesting that divergence in mating behavior among Laupala species is due to the fixation of many genes of minor effect. The diversity of acoustic signaling systems in crickets exemplifies the evolution of elaborate male displays by sexual selection through female choice. Our data reveal genetic conditions that would enable functional coordination between song and acoustic preference divergence during speciation, resulting in a behaviorally coupled mode of signalpreference evolution. Interestingly, Laupala exhibits one of the fastest rates of speciation in animals, concomitant with equally rapid evolution in sexual signaling behaviors. Genomic linkage may facilitate rapid speciation by contributing to genetic correlations between sexual signaling behaviors that eventually cause sexual isolation between diverging populations.Laupala ͉ sexual isolation ͉ signal ͉ speciation

“…This might be almost inevitable when there are intimate associations between traits under ecological selection and assortative mating, such as those seen for flowering time in plants (Hall et al, 2006) or nest structure and body size in sticklebacks (Ólafsdót-tir et al, 2006). The importance of ecological plasticity to significant variation in mating signals or preferences is poorly understood (Olvido and Mousseau, 1995), in particular we know of no study which has addressed if plasticity could influence multiple effect (or 'magic') traits by facilitating the phenotypic linkage of ecological adaptation and assortative mating.…”

Speciation research has seen a renewed interest in ecological speciation, which emphasises divergent ecological selection leading to the evolution of reproductive isolation. Selection from divergent ecologies means that phenotypic plasticity can play an important role in ecological speciation. Phenotypic plasticity involves the induction of phenotypes over the lifetime of an organism and emerging evidence suggests that epigenetic marks such as cytosine and protein (histone) modifications might regulate such environmental induction. Epigenetic marks play a wide role in a variety of processes including development, sex differentiation and allocation, sexual conflict, regulation of transposable elements and phenotypic plasticity. Here we describe recent studies that investigate epigenetic mechanisms in a variety of contexts. There is mounting evidence for environmentally induced epigenetic variation and for the stable inheritance of epigenetic marks between generations. Thus, epigenetically-based phenotypic plasticity may play a role in adaptation and ecological speciation. However, there is less evidence for the inheritance of induced epigenetic variation across multiple generations in animals. Currently few studies of ecological speciation incorporate the potential for the involvement of epigenetically-based induction of phenotypes, and we argue that this is an important omission

“…Diet quality influences horn length in beetles (Emlen 1994), eye span in stalk-eyed flies (Knell et al 1999;David et al 2000) and wattle colour in pheasants (Ohlsson et al 2002). In the striped ground cricket Allonemobius fasciatus variation in calling-song characteristics is related to rearing temperature (Olvido & Mousseau 1995). However, experimental support for the proposition that multiple male ornaments may specifically serve to reflect condition over different time-scales (Møller & Pomiankowski 1993) is lacking.…”

Sexual-selection theory predicts that multiple signals may reveal male condition at different stages of life, thus allowing females to make a more reliable assessment of male quality. While the effect of current condition on signal design is well established, few studies have experimentally investigated the effects of past condition. We therefore manipulated the nutritional condition of male nymph field crickets Gryllus campestris and assessed the enduring effects on multiple components of the adult calling song. Foodrestricted males had longer nymphal development times and smaller adult body sizes than nymphs with ad libitum food access. Nymphal feeding conditions specifically affected the allometric relationship between body size and harp size, as food-restricted males developed comparatively small harps, leading to a calling song of higher carrier frequency than that produced by similar-sized control males. Other calling-song components, notably chirp rate and chirp intensity, were not affected by the nymphal food treatment, exposing carrier frequency as the key component indicating past condition. In a previous study we established chirp rate as the sole indicator of current condition. The combined results represent experimental evidence of a multicomponent sexual signal that provides distinct information on male condition during different stages of life.
