One dramatic consequence of changes in the MRS is the failure of individuals from divergent lineages to successfully court and mate, thereby reducing gene flow between these groups. Here, we test the role of an acoustic mating signal on mate choice in a Hawaiian cricket genus (Gryllidae: Laupala). Speciation in Laupala is proceeding at an extremely rapid rate, apparently driven by divergence in aspects of the mate recognition system, most conspicuously the pulse rate of male calling song. Previous studies demonstrate that females prefer the pulse rate of a conspecific male{\textquoteright}s song when perceived at long range, in laboratory phonotaxis trials. In this study, we examined mate choice in two species that differ dramatically in pulse rate: Laupala paranigra and Laupala kohalensis. We tested the female{\textquoteright}s preference in both species for pulse rates at close range, by providing females an opportunity to mate with hybrid males producing a range of intermediate pulse rates. Results of our study demonstrate that while strong behavioral barriers exist between these two species, variation in the pulse rate of male calling song did not predict female mate choice at close range. These results suggest a more complex architecture to mate recognition in Laupala than previously hypothesized.}, keywords = {behaviour, communication, crickets, hawaii, orthoptera}, doi = {10.1007/s00265-005-0107-7}, url = {http://dx.doi.org/10.1007/s00265-005-0107-7}, author = {Mendelson, Tamra and Shaw, Kerry} } @article {Robert2009Insect, title = {Insect Bioacoustics: Mosquitoes Make an Effort to Listen to Each Other}, journal = {Current Biology}, volume = {19}, number = {11}, year = {2009}, month = {June}, pages = {R446{\textendash}R449}, keywords = {bioacoustics, communication, hearing, insects}, issn = {09609822}, doi = {10.1016/j.cub.2009.04.021}, url = {http://dx.doi.org/10.1016/j.cub.2009.04.021}, author = {Robert, Daniel} } @article {GeberzahnFemales, title = {Females alter their song when challenged in a sex-role reversed bird species}, journal = {Behavioral Ecology and Sociobiology}, year = {Submitted}, abstract = {Abstract\ \ Birdsong serves to attract mates and to deter territorial rivals. Even though song is not restricted to males, this dual function has almost exclusively been demonstrated for male song. To test the generality of hypotheses on birdsong, we investigated female song in the sex-role reversed, classically polyandrous African black coucal (Centropus grillii) in the context of female{\textendash}female competition. We compared spontaneously vocalizing females with females vocally responding to a playback simulating a conspecific intruder. Females changed vocal parameters in response to playbacks: They lowered the pitch of their vocalizations and enhanced the duration of song elements when being challenged. Also, the composition of the vocalizations was altered. There was no significant correlation between pitch and body size parameters in spontaneous song, but there was for response songs, with larger females having a lower pitch. These changes in vocal properties suggest that the vocalizations are important for mutual assessment of competitive abilities in females. Our findings confirm the general role of intrasexual competition in vocal communication of birds.}, keywords = {bioacoustics, birds, communication, song}, doi = {10.1007/s00265-009-0836-0}, url = {http://dx.doi.org/10.1007/s00265-009-0836-0}, author = {Geberzahn, Nicole and Goymann, Wolfgang and Muck, Christina and ten Cate, Carel} } @article {Hall2008EXPERIMENTAL, title = {EXPERIMENTAL EVIDENCE THAT SEXUAL CONFLICT INFLUENCES THE OPPORTUNITY, FORM AND INTENSITY OF SEXUAL SELECTION}, journal = {Evolution}, volume = {62}, number = {9}, year = {2008}, pages = {2305{\textendash}2315}, address = {Evolution \& Ecology Research Centre and School of Biological, Earth \& Environmental Sciences, University of New South Wales, Sydney, New South Wales 2052, Australia; E-mail: m.hall@student.unsw.edu.au; Zoologisches Museum der Universitt Zrich, Winterthure}, abstract = {Sexual interactions are often rife with conflict. Conflict between members of the same sex over opportunities to mate has long been understood to effect evolution via sexual selection. Although conflict between males and females is now understood to be widespread, such conflict is seldom considered in the same light as a general agent of sexual selection. Any interaction between males or females that generates variation in fitness, whether due to conflict, competition or mate choice, can potentially influence sexual selection acting on a range of male traits. Here we seek to address a lack of direct experimental evidence for how sexual conflict influences sexual selection more broadly. We manipulate a major source of sexual conflict in the black field cricket, Teleogryllus commodus, and quantify the resulting changes in the nature of sexual selection using formal selection analysis to statistically compare multivariate fitness surfaces. In T. commodus, sexual conflict occurs over the attachment time of an external spermatophore. By experimentally manipulating the ability of males and females to influence spermatophore attachment, we found that sexual conflict significantly influences the opportunity, form, and intensity of sexual selection on male courtship call and body size. When males were able to harass females, the opportunity for selection was smaller, the form of selection changed, and sexual selection was weaker. We discuss the broader evolutionary implications of these findings, including the contributions of sexual conflict to fluctuating sexual selection and the maintenance of additive genetic variation.}, keywords = {communication, crickets, mating, orthoptera, sexual-selection}, doi = {10.1111/j.1558-5646.2008.00436.x}, url = {http://dx.doi.org/10.1111/j.1558-5646.2008.00436.x}, author = {Hall, Matthew D. and Bussi{\`e}re, Luc F. and Hunt, John and Brooks, Robert} } @article {Bailey1983SOUND, title = {SOUND PRODUCTION IN MICRONECTA BATILLA HALE (HEMIPTERA: CORIXIDAE)?AN ALTERNATIVE STRUCTURE}, journal = {Australian Journal of Entomology}, volume = {22}, number = {1}, year = {1983}, month = {February}, pages = {35{\textendash}38}, keywords = {bioacoustics, communication, hemiptera, insecta, stridulation, waterbugs}, issn = {1326-6756}, doi = {10.1111/j.1440-6055.1983.tb01836.x}, url = {http://dx.doi.org/10.1111/j.1440-6055.1983.tb01836.x}, author = {Bailey, Winston J.} } @article {Rodriguez2006Evidence, title = {Evidence that female preferences have shaped male signal evolution in a clade of specialized plant-feeding insects}, journal = {Proceedings of the Royal Society B: Biological Sciences}, volume = {273}, number = {1601}, year = {2006}, month = {October}, pages = {2585{\textendash}2593}, abstract = {10.1098/rspb.2006.3635 Mate choice is considered an important influence in the evolution of mating signals and other sexual traits, and{\textemdash}since divergence in sexual traits causes reproductive isolation{\textemdash}it can be an agent of population divergence. The importance of mate choice in signal evolution can be evaluated by comparing male signal traits with female preference functions, taking into account the shape and strength of preferences. Specifically, when preferences are closed (favouring intermediate values), there should be a correlation between the preferred values and the trait means, and stronger preferences should be associated with greater preference{\textendash}signal correspondence and lower signal variability. When preferences are open (favouring extreme values), signal traits are not only expected to be more variable, but should also be shifted towards the preferred values. We tested the role of female preferences in signal evolution in the species complex of treehoppers, a clade of plant-feeding insects hypothesized to have speciated in sympatry.

We raised female under conditions that reliably induced either summer or winter phenotype and tested their preferences for the call parameters that differ between summer and winter males. Neither generation was selective for the presence of verses, but females had strong preferences for pulse rates: only a narrow range of pulse rates was attractive. The attractive ranges did not differ between summer and winter females. Both male pulse rate and female preference for pulse rate changed with ambient temperature, but female preference changed more than the male calls. As a result, the summer call was attractive only at 25{\textdegree}C, whereas the slower winter call was attractive only at 20{\textdegree}C. Thus, developmental plasticity of male calls compensates for differences in temperature dependency between calls and preferences and enables the communication system to function in heterogeneous environments.

Two rows of spines on abdominal tergites II and III of both species are rubbed by an elongate area of tubercules on the inner femoral surface of the hind legs. Analysis showed that the motion of the leg relative to the abdomen involves a complex counter-rotation of the leg between leg and abdomen. The defensive display may be performed in day light. Social signalling in both species occurs after dark, and involves drumming on the substrate by both hind legs in loose synchrony. Drumming is rhythmic and species{\textquoteright} specific.

However, there is little experimental evidence for the importance of acoustic signals in social contexts and the influence of sound on mating decisions of females. Cichlid fish are known for their bright nuptial coloration, which plays an important role in mate choice and reproductive isolation between the many species of cichlid fish in East Africa. They also produce sounds in both aggressive and courtship interactions. In this study, we show that the sounds produced by males of Lake Victoria cichlids are species specific. There is also a correlation between fish size and peak frequency of sounds across species. We did not find context-dependent differences within a species (Pundamilia nyererei) between male sounds produced during aggressive displays toward males or sexual displays toward females. We also show with playback experiments that courtship sounds influence the mate preferences of female cichlids.

However, it has been suggested that echolocation calls may also have a communicative function, for instance between roost members. In principle, this seems possible because echolocation calls are species specific and known to differ between the sexes, and between colonies and individuals for some species. We performed playback experiments with lesser bulldog bats, Noctilio albiventris , to which we presented calls of familiar/unfamiliar conspecifics, cohabitant/noncohabitant heterospecifics and ultrasonic white noise as a control. Bats reacted with a complex repertoire of social behaviours and the intensity of their response differed significantly between stimulus categories. Stronger reactions were shown towards echolocation calls of unfamiliar conspecifics than towards heterospecifics and white noise. To our knowledge, this is the first time that bats have been found to react to echolocation calls with a suite of social behaviours. Our results also provide the first experimental evidence for acoustical differentiation by bats between familiar and unfamiliar conspecifics, and of heterospecifics. Analysis of echolocation calls confirmed significant individual differences between echolocation calls. In addition, we found a nonsignificant trend towards group signatures in echolocation calls of N. albiventris .
