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 . We document a QTL underlying female acoustic preference variation between 2 closely related species ( and ). 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 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 signal-preference evolution. Interestingly, 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.10abioacoustics10acrickets10aevolution10aorthopera10aradiation10asong1 aShaw, Kerry, L.1 aLesnick, Sky, C.  uhttp://dx.doi.org/10.1073/pnas.090022910601819nas a2200193   4500008004100000245009600041210006900137260001000206300001400216490000800230520124300238653001701481653001301498653001501511653001001526100002001536700002401556856004501580       2000                        eng d00aAcoustic preference functions and song variability in the Hawaiian cricket Laupala cerasina0 aAcoustic preference functions and song variability in the Hawaii  cMarch  a577–5840 v2673 a10.1098/rspb.2000.1040 Female preference functions for different sexual traits can differ significantly, from 'unimodal' to 'open ended'. Through the study of acoustic communication in anurans, several studies have reported an association between static (stereotyped) traits versus dynamic (variable) traits and preference function shape (unimodal versus open ended, respectively). Observing a similar pattern in a phylogenetically independent group would suggest that deterministic forces have caused a relationship between signal variability and preference function shape in acoustic signalling systems. We examined this phenomenon in crickets, another animal characterized by intersexual acoustic communication. We measured the within–male variability for three acoustic features of the male calling song in and the corresponding shape of the female preference function for each of these features. We offer support for the generalization that open–ended preference functions correspond to relatively dynamic courtship traits and unimodal preference functions correspond to relatively static courtship traits. We discuss the evolutionary significance of these findings in the context of the natural history of the species radiation.10abioacoustics10acrickets10aorthoptera10asongs1 aShaw, Kerry, L.1 aHerlihy, Daniel, P.  uhttp://dx.doi.org/10.1098/rspb.2000.104001818nas a2200181   4500008004100000245017300041210006900214260001300283300001800296490000700314520119400321653001701515653001301532653001101545653001501556100002001571856004501591       2002                        eng d00aConflict between nuclear and mitochondrial DNA phylogenies of a recent species radiation: What mtDNA reveals and conceals about modes of speciation in Hawaiian crickets0 aConflict between nuclear and mitochondrial DNA phylogenies of a   cDecember  a16122–161270 v993 a10.1073/pnas.242585899 It has been asserted that recent mtDNA phylogenies support the plausibility of sympatric speciation, long considered a controversial mechanism of the origin of species. If such inferences are reliable, mtDNA phylogenies should be congruent with phylogenies based on other data. In previous work, a mtDNA phylogeny suggested that diversification of the Hawaiian cricket genus was initiated by single invasions into each of several Hawaiian islands, followed by multiple sympatric divergences within each island. In contrast, a systematic hypothesis based on morphology argues that speciation in has occurred primarily in allopatry, with two independent species radiations diversifying across the archipelago. In this study, I analyze nuclear DNA (nDNA) sequences from to compare with sequences from the mtDNA. The nDNA phylogeny corroborates the hypothesis of allopatric divergence and multiple invasions, and when compared with mtDNA patterns, suggests that interspecific hybridization is a persistent feature of the history of . The discrepancy between mtDNA and nDNA phylogenies reveals that speciation histories based on mtDNA alone can be extensively misleading.10abioacoustics10acrickets10ahawaii10aspeciation1 aShaw, Kerry, L.  uhttp://dx.doi.org/10.1073/pnas.242585899
