Vibrational communication is important for successful mating in various stink bugs species. The vibrational signals from males and females of Dichelops melacanthus Dallas (Hemiptera: Pentatomidae) are recorded from a nonresonant substrate (i.e. a loudspeaker membrane) to characterize the temporal and spectral properties of these vibrational signals, as well as on a resonant substrate (i.e. bean plants) to obtain information about how these signals are altered when they are transmitted through the plants. On the loudspeaker membrane, D. melacanthus males and females emit only one male or one female song, respectively. However, when the insects are placed on bean leaves, a more complex repertoire is recorded, with three different songs for each sex. The first female and male songs appear to have calling functions and the third male and female songs are emitted during courtship. The second female and male songs are emitted after the first song, although their functions in mating behaviour are not clear. The identified repertoire is similar to those of other Neotropical stink bugs, starting with songs 1 and 2 and developing into song 3. Frequency modulation is observed in the female songs recorded from the loudspeaker membrane and the plants. The signals recorded from plants present higher harmonic peaks compared with the signals recorded from the loudspeaker membrane. The presence of species and sex‐specific songs during mating confirms the important role of vibrational communication in mate location and recognition. The temporal and spectral characteristic signals are influenced by the substrate used to record the songs emitted by D. melacanthus. 相似文献

In animal communication systems, matching mating signals and preferences enable species identification and successful reproduction. In some species, the environment introduces substantial variation in signals and/or preferences. Only a few studies have tested how the match between signals and preferences is maintained despite phenotypic variation. Signal–preference coupling in the context of phenotypic plasticity is the focus of this study. The bivoltine cricket Gryllus rubens displays seasonal differences in the pulse rate of its mating songs. The seasonal effect on other fine‐temporal characters of the songs besides pulse rate, such as pulse and interval duration, duty cycle, as well as the dominant frequency, is not known and is described in the first part of the study for a Kentucky population. In the second part of the study, we tested preferences of spring and fall females to determine whether they match the seasonal plasticity of male songs using single‐speaker phonotaxis experiments. We found that fall songs had a faster pulse rate, shorter pulse and interval durations, and a higher dominant frequency than spring songs. Female preferences shifted in parallel with male song plasticity, that is, spring females preferred the spring song and fall females the fall song. In addition, female responsiveness to male song was plastic as well, that is, fall females were significantly more responsive than spring females. The parallel plasticity of male songs and female preferences facilitates successful communication despite the environmentally induced variation. The potential origin and function of behavioral plasticity in G. rubens are discussed. 相似文献

Songs emitted during mating by male and female Holcostethus strictus were recorded as substrate vibrations. Spectra of the vibrational signals have a dominant frequency peak between 100 and 260 Hz and in this respect reflect the general characteristic of the family Pentatomidae. Songs of H. strictus differ from the song repertoire of the southern green stink bug Nezara viridula (L.) (Pentatomidae) in many respects. The female calling and courtship songs differ in echeme and phrase duration. The male calling song is composed of spectrally different subunits. The male courtship song is characterised by three types of spectrally and temporally different echemes. The male copulatory song is composed of echemes of two types, which constitute a phrase of less regular temporal structure. In H. strictus, males start to sing first and female songs are less complex than in N. viridula. The female calling song is evoked by male calling and does not trigger male response. The female and male courtship song phrases are superimposed on one another and we have not observed any obvious regularity in their exchange. The possible role of different songs in H. strictus is discussed and compared with that in other pentatomide landbug species. 相似文献

Divergence of male sexual signals and female preferences for those signals often maintains reproductive boundaries between closely related, co‐occurring species. However, contrasting sources of selection, such as interspecific competition, can lead to weak divergence or even convergence of sexual signals in sympatry. When signals converge, assortative mating can be maintained if the mating preferences of females diverge in sympatry (reproductive character displacement; RCD), but there are few explicit examples. Pied flycatchers (Ficedula hypoleuca) are sympatric with collared flycatchers (F. albicollis) on the Baltic island of Öland, where males from both species compete over nestboxes, their songs converge, and the two species occasionally hybridize. We compare song discrimination of male and female pied flycatchers on Öland and in an allopatric population on the Swedish mainland. Using field choice trials, we show that male pied flycatchers respond similarly to the songs of both species in sympatry and allopatry, while female pied flycatchers express stronger discrimination against heterospecific songs in sympatry than in allopatry. These results are consistent with RCD of song discrimination of female pied flycatchers where they co‐occur with collared flycatchers, which should maintain species assortative mating despite convergence of male sexual signals. 相似文献

Many aspects of the social behaviour of birds are mediated by vocal displays, and variation in song output or song structure conveys different information to receivers. After nest construction begins, when vermilion flycatcher (Pyrocephalus rubinus) females are potentially fertile, males increase their song rate during the dawn chorus. A previous study failed to give evidence that males discriminate among song rates. However, males sing in sequences of songs (song bouts), and an increase in song rate may be achieved by increasing the number of bouts, the number of songs in each bout (bout size) or both. Studying a vermilion flycatcher population in Mexico City, we evaluated whether dawn song rate is related to song bout size or to number of bouts. Bout size correlated with song rate and differed among males. We hypothesized that longer bouts are more threatening signals than shorter ones and predicted a stronger response by males towards the former. We exposed each male to three playback treatments: (1) Long song bout (Long), in which we replied to the male with twice the number of songs he sang in the bout, (2) Short song bout (Short), in which we played half the number of songs sung by the male and (3) Control, this was the same as the Long treatment but we used songs from a related species, the tropical kingbird (Tyrannus melancholicus). Males responded with a higher proportion of calls near the speaker when exposed to the Long treatment than during the Short or Control treatments, indicating that they discriminate among song bouts differing in size, that they may perceive longer bouts as more threatening and that they use calls rather than songs to address threatening situations. Our results suggest that song bout size is a relevant song attribute that conveys information during intrasexual interactions. 相似文献

The learned songs of songbirds often cluster into population-wide types. Here, we test the hypothesis that male and female receivers respond differently to songs depending on how typical of those types they are. We used computational methods to cluster a large sample of swamp sparrow (Melospiza georgiana) songs into types and to estimate the degree to which individual song exemplars are typical of these types. We then played exemplars to male and female receivers. Territorial males responded more aggressively and captive females performed more sexual displays in response to songs that are highly typical than to songs that are less typical. Previous studies have demonstrated that songbirds distinguish song types that are typical for their species, or for their population, from those that are not. Our results show that swamp sparrows also discriminate typical from less typical exemplars within learned song-type categories. In addition, our results suggest that more typical versions of song types function better, at least in male–female communication. This finding is consistent with the hypothesis that syllable type typicality serves as a proxy for the assessment of song learning accuracy. 相似文献

Diverging sexual communication systems can lead to the evolution of new species that no longer recognize each other as potential mates. The coevolution of male and female components of sexual communication is facilitated by physical linkage between genes underlying signals and preferences. By crossing two closely related Hawaiian crickets (Laupala kohalensis and Laupala paranigra) with vastly different song pulse rates and female preferences, and assessing segregation of songs and preferences among second generation backcrosses, we show a strong genetic correlation between song and preference variation. Furthermore, multiple, but not all, quantitative trait loci underlying song variation also predict female preferences. This physical linkage or pleiotropy may have facilitated the striking diversification of pulse rates observed among Laupala species in conjunction with one of the most rapid species radiations so far recorded. 相似文献

We carried out two experiments across 2 yr on song perception in female cowbirds (Molothrus ater). In the first experiment, juvenile and adult female brown‐headed cowbirds, living in same‐sex flocks in outdoor aviaries, were periodically tutored with recordings of local male cowbirds’ songs. In the spring, four adult male cowbirds were placed with half of the females for a 12‐d period. We then tested song preferences of all females by measuring copulation solicitation displays during the breeding season. We found that the females exposed only to tape‐tutor songs preferred those songs to those of the unfamiliar males used as companions and that the females allowed to interact with males preferred their songs over the familiar tape‐tutor songs. These data establish the modifiability of female cowbirds’ song preferences at the level of local song. In a second experiment, we studied the playback responses of juvenile females, hand‐reared from the egg, who were tape‐tutored only in the spring in the presence or absence of adult females. There were no differences between the responses of juveniles housed with or without adult females and the hand‐reared juveniles were significantly less responsive to song than adult females. Adult females responded more to familiar songs than to the unfamiliar songs: juvenile females made no such distinction. Taken as a whole, these data are the first to document that female cowbirds’ song preferences for local song can be reshaped by post‐natal experience. These data complement recent study in cowbirds and other species showing that socially more complex contexts reveal plasticity in female song preferences that are not apparent when learning opportunities are constrained by impoverished laboratory settings. 相似文献

Hardly any behavioral data are available for the silvery gibbon (Hylobates moloch), an endangered primate that is endemic to the island of Java, Indonesia. We studied the singing behavior of the easternmost population of this species in the Dieng mountains, central Java, in 1998-1999. We aimed to document the timing of singing, quantify the amount of singing by the respective sexes, and explore the role of bioacoustics in density estimation. A total of 122 song bouts in at least 12 groups were monitored. No duet songs were heard. Most of the song bouts (91.5%) were female solo song bouts or female scream bouts. In contrast to an earlier study on the westernmost population of silvery gibbons, during which few if any male songs were heard, at least 8.5% of the song bouts in our study were male solo song bouts. They were significantly longer in duration than the female songs. All male song bouts uttered before dawn (0520 hr) were produced in a chorus fashion, with at least three individuals participating. Choruses occurred about once every 8.5 days, and lasted longer and occurred earlier than female solo song bouts. Most male songs (60%) started between 0355-0440 hr, when it was still dark. All female songs, in contrast, started after 0500 hr, and female singing activity peaked around 0600. Regular male singing, male chorusing, and regular predawn singing have not previously been reported for silvery gibbons. Similarly separated periods of male and female solo songs and the absence of duetting have been observed in Kloss's gibbons (H. klossii) on the Mentawai Islands, and may represent synapomorphies shared by both species. The pronounced individual-specific song characteristics of silvery gibbons allow accurate mapping of groups. The density of gibbons at our study site was established to be 1.9-3.7 groups/km2, corresponding to 6.7-13.1 individuals/km2. We reassess the suitability of gibbon songs as a means of estimating the density and size of gibbon populations, and discuss the proximate causes for the absence of duetting in silvery gibbons. 相似文献

Geographic variation in male bird songs has been studied extensively, but there have been few investigations of geographic variation in female songs or sex differences in patterns of geographic variation. We compared patterns of variation in male and female songs of eastern whipbirds Psophodes olivaceus by analyzing recordings from 16 populations across the species’ geographic range in eastern Australia. We found remarkably different patterns of geographic variation between the sexes. Female eastern whipbird songs are easily categorized into discrete song types. Song types are shared between nearby females, but female songs show pronounced differences at a continental scale. In contrast, male eastern whipbird songs show high consistency throughout the species’ geographic range. All recorded males share the ability to transpose the frequency of the introductory whistle and most recorded males share the ability to vary the direction of the slope of the terminal whip crack. For eight of nine measured variables, female songs show significantly higher levels of variation than male songs. We discuss whether sex differences in dispersal, song learning strategies, and song function may explain these sex differences in patterns of song variation. We suggest that eastern whipbirds have experienced a decoupling of male and female song learning strategies and that the songs of each sex have responded to different selective pressures in the context of countersinging interactions. We speculate that consistency in male songs throughout the geographic range of eastern whipbirds may arise through female preference for males that perform large bandwidth whip cracks. 相似文献

Interspecific territoriality is frequently reported between closely related species; however, few studies have demonstrated interspecific territoriality between distantly related species living in sympatry. We conducted playback experiments to investigate territorial behaviour in male and female White‐bellied Wrens (Uropsila leucogastra) in response to simulated conspecific and heterospecific intruders during the breeding and non‐breeding seasons. We explored whether heterospecific songs of the Happy Wren (Pheugopedius felix), a distantly related species and ecological competitor, elicited antagonistic responses from focal White‐bellied Wrens, and whether such responses differed between the sexes. We also examined whether male and female responses to conspecific and heterospecific rivals varied with season. We found that male White‐bellied Wrens always responded to conspecific song, and responded significantly more to heterospecific song compared to a control stimulus (Tropical Parula, Setophaga pitiayumi). In contrast, although female White‐bellied Wrens responded strongly to conspecific song, their response to heterospecific song did not differ significantly from the control stimulus. The proportion of males that responded to heterospecific songs and the proportion of females that responded to conspecific songs varied seasonally, showing significantly lower responses during the breeding season. The intense responses of male White‐bellied Wrens to playback of heterospecific songs suggest that they recognise ecological competitors based on their vocal signals. Furthermore, the decrease in agonistic interactions during the breeding season is in line with the hypothesis that aggressive behaviour may be detrimental to reproductive and parental activity, and the hypothesis that heterospecific animals pose less of a threat during the breeding season. 相似文献

The Wheat dwarf virus, the causal agent of the wheat dwarf disease, is transmitted by leafhoppers from the genus Psammotettix and currently the main protection strategy is based on the use of insecticide treatments. Sustainable management strategies for insect vectors should include methods that are targeted to disrupt reproductive behavior and here we investigated the mating behavior of Psammotettix alineus (Dahlbom 1850) in order to determine the role of vibrational signals in intra‐specific communication and pair formation. Both genders spontaneously emit species‐ and sex‐specific calling songs that consisted of regularly repeated pulse trains and differ primarily in pulse train duration and pulse repetition time. Females preferred the conspecific male calling song. After a coordinated exchange of pulse trains, the male approached the stationary female. During the close range courtship and also immediately prior to copulatory attempts distinct male vibrational signals associated with wing flapping and wing vibrations were recorded from the substrate. In the presence of a receptive female, competing males emitted vibrational signals most likely aimed to interfere with male‐female interaction. Mated females regained sexual receptivity after they laid eggs. Although results suggest that the viruliferous status of insects may have an effect on vibrational songs, our current results did not reveal a significant effect of virus on leafhopper performance in mating behavior. However, this study also suggests, that detailed understanding of plant–vector–virus interactions relevant for vector mating behavior is essential for trying new approaches in developing future control practices against plant viruses transmitted by insect vectors. 相似文献

Gibbons are characterized by their species-specific calls, or songs. There are few studies of songs of Hainan gibbon (Nomascus hainanus). To study the sound spectrum characteristics and test for intergroup differences in Hainan gibbon song, we studied the singing behavior of Hainan gibbons in Bawangling National Nature Reserve, Hainan Province, China, intermittently from August 2002 to February 2013, collecting 184 recordings. Our results show that: 1) Hainan gibbon song bouts occur mainly 0–4 h after dawn. 2) The songs of adult males living in groups are composed mainly of one to three short notes and one to five long notes, while solitary adult male songs consist only of long frequency modulated notes and no short or single notes. 3) The song chorus is dominated by adult males, while females add a great call. Males do not have a great call, unlike those in other gibbon species. There are no female solos. 4) The sound spectrum frequency is similar in adult males living in two different groups, but the duration of the first long note differed significantly between the groups. The sonic frequencies of male and female songs are lower than those of other gibbons: no more than 2 kHz. Hainan gibbon sound structure is simple, although females participate in the chorus, reflecting their primitive status among gibbon species. 相似文献

The structure of male songs and the timing of female replies with respect to the male songs are described for four species of the palaearctic bushcricket genus Barbitistes (B. constrictus, B. ocskayi, B. serricauda, B. yersini). In a male song, 3 to 16 syllables form a chirp followed by a trigger syllable after a longer interval. The trigger syllable releases a female reply with a latency of 30 to 50 ms in all four species. In B. serricauda songs, there is no clearly separated trigger syllable. Instead, the first syllable of a chirp functions as a trigger syllable. Some B. serricauda males may produce a short female-type syllable just at the moment, when a female would reply. The possible function of such a syllable is acoustical mimicry. When comparing at least two song parameters, each species occupies a specific combination of values. According to the overlap of parameters a close phylogenetic relationship between B. constrictus and B. serricauda and between B. ocskayi and B. yersini is assumed. This interpretation is compared with a hypothesis based on morphological investigations. 相似文献

The effectiveness of hybridization barriers determines whether two species remain reproductively isolated when their populations
come into contact. We investigated acoustic mating signals and associated leg movements responsible for song creation of hybrids
between the grasshopper species Chorthippus biguttulus and C. brunneus to study whether and how songs of male hybrids contribute to reproductive isolation between these sympatrically occurring
species. Songs of F1, F2, and backcross hybrids were intermediate between those of both parental species in terms phrase number
and duration. In contrast, species-specific syllable structure within phrases was largely lost in hybrids and was produced,
if at all, in an irregular and imperfect manner. These divergences in inheritance of different song parameters are likely
the result of incompatibility of neuronal networks that control stridulatory leg movements in hybrids. It is highly probable
that songs of hybrid males are unattractive to females of either parental species because they are intermediate in terms of
phrase duration and lack a clear syllable structure. Males of various hybrid types (F1, F2, and backcrosses) are behaviorally
sterile because their songs fail to attract mates. 相似文献

Courtship behaviour and songs of six Zaprionus species show differences not only between species but also between sexes. Courtship behaviour differs from that in the related genus Drosophila. In most species, males produce two song types which may alternate or be repeated. Singing occurs during courtship displays, mounting, after copulation and briefly during male-to-male interactions. Females produce a loud whine and body rocking movements in refusal but have a species-specific pulsed song produced during normal courtship which differs from the conspecific male song. One species produces an irregular male song but a regular female song. Sex-specific songs may have selective advantages but pose problems for the sensory template hypothesis. 相似文献

Many animals defend territories against conspecific individuals using acoustic signals. In birds, male vocalizations are known to play a critical role in territory defence. Territorial acoustic signals in females have been poorly studied, perhaps because female song is uncommon in north‐temperate ecosystems. In this study, we compare male vs. female territorial singing behaviour in Neotropical rufous‐and‐white wrens Thryothorus rufalbus, a species where both sexes produce solo songs and often coordinate their songs in vocal duets. We recorded free‐living birds in Costa Rica using an eight‐microphone Acoustic Location System capable of passively triangulating the position of animals based on their vocalizations. We recorded 17 pairs of birds for 2–4 consecutive mornings and calculated the territory of each individual as a 95% fixed kernel estimate around their song posts. We compared territories calculated around male vs. female song posts, including separate analyses of solo vs. duet song posts. These spatial analyses of singing behaviour reveal that males and females use similarly sized territories with more than 60% overlap between breeding partners. Territories calculated based on solo vs. duet song posts were of similar size and similar degrees of overlap. Solos and duets were performed at similar distances from the nest for both sexes. Overall, male and female rufous‐and‐white wrens exhibit very similar spatial territorial singing behaviour, demonstrating congruent patterns of male and female territoriality. 相似文献

Although traits of related species are likely to be similar due to common ancestry, mating signals are an exception. In singing insects, for example, song similarity has been documented only for allopatric or allochronic species pairs, and even then, not often. Where song similarity does occur, it has been logically attributed to the inheritance of ancestral traits rather than convergence. It is quite common for related, sympatric insect species to differ dramatically in calling song, which is predicted by evolutionary theory to maximize intraspecific mating success. Given that there are a limited number of ways to make sounds on anatomically similar organs and given that there would be no selective pressure for songs to differ in widely separated geographic areas, convergence in songs among related species living on different continents might be expected. Here we present the first well-documented case of such convergence, in a group of sibling, cryptic species characterized by substrate-borne vibrational mating songs. In this example from green lacewings of the carnea group of the genus Chrysoperla, a variety of statistical tests shows that one species in North America and another in Asia possess songs that are strikingly similar to each other. DNA data demonstrate that the species involved belong to divergent speciose lineages, and behavioral data demonstrate that the convergent songs are readily accepted by members of both species. 相似文献

The song of the male bushcricket Ancistrura nigrovittata consists of a sequence of verses. Each verse comprises a syllable group, plus, after about 400 ms a single syllable serving as a trigger for the female response song. The carrier frequency of the male song spectrum peaks at around 15 kHz, while the female song peaks at around 27 kHz. The thresholds of female responses to models of male songs are lowest for song frequencies between 12 and 16 kHz and therefore correspond to the male song spectrum. The threshold curve of the female response to the trigger syllable at different frequencies has the same shape as the tuning for the syllable group. Phonotactic thresholds of male Ancistrura nigrovittata to synthetic female responses at different frequencies are lowest between 24 and 28 kHz and thereby correspond to the female song spectrum and clearly differ from female response thresholds. Activity of the tympanic fibre bundle of both sexes is most sensitive between 15 and 35 kHz and therefore not specifically tuned to the partner's song. Individual behavioural thresholds have their minimum within 10 dB of the values of tympanic thresholds. 相似文献
