Abstract:

Primates give alarm calls in response to the presence of predators. In some species, such as the Thomas langur ( Presbytis thomasi ), males only emit alarm calls if there is an audience. An unanswered question is whether the audience's behaviour influences how long the male will continue his alarm calling. We tested three hypotheses that might explain the alarm calling duration of male Thomas langurs: the fatigue , group size and group member behaviour hypotheses. Fatigue and group size did not influence male alarm calling duration. We found that males only ceased calling shortly after all individuals in his group had given at least one alarm call. This shows that males keep track of and thus remember which group members have called.

Abstract:

AbstractSexual traits are typically thought to convey information about a male's quality or condition. Female preference for older males has been documented in many taxa, but the evidence that males signal their age is inconclusive. We investigated lifetime patterns of acoustic mate attraction signalling in a longitudinal study of the spring field cricket, Gryllus veletis. We recorded males continuously throughout their lives, such that every pulse of sound produced by every male was analyzed. Our study answers two main questions: (1) Do calls change as males age? Our results reveal that the calls of male spring field crickets change with age; the calls of older males were quieter, with more silent periods within and between chirps, and produced less often than those of younger males. As males aged most of the changes in call structure reflect decreased calling effort. (2) What is the relationship between calling effort and longevity? Lifetime calling effort was positively related to longevity, such that males that called the most over their life also lived longer than males that called less. Together, our findings provide the most thorough exploration of lifetime signalling patterns in crickets to date.

Abstract:

[abstFig src='/00290001/23.jpg' width='300' text='Calling behavior of a male Japanese Tree Frog' ] Sensing the external environment is a core function of robots and autonomous mechanics. This function is useful for monitoring and analyzing the ecosystem for our deeper understanding of the nature and accomplishing the sustainable ecosystem. Here, we investigate calling behavior of male frogs by applying audio-processing technique on multiple audio data. In general, male frogs call from their breeding site, and a female frog approaches one of the males by hearing their calls. First, we conducted an indoor experiment to record spontaneous calling behavior of three male Japanese tree frogs, and then separated their call signals according to independent component analysis. The analysis of separated signals shows that chorus size (i.e., the number of calling frogs) has a positive effect on call number, inter-call intervals, and chorus duration. We speculate that a competition in a large chorus encourages the male frogs to make their call properties more attractive to conspecific females.

Abstract:

The Xhosa male initiation practice, as it was viewed in the past, is discussed by focusing on its impact upon the initiates, its contribution to the moral upholding of values and its role in promoting the values of ‘ ubuntu’. The present circumstances surrounding the initiation practice are also evaluated. The outcry of Church and other leaders, who are calling for the practice to be abolished, is recognized. The author asserts that, because of the importance of this practice to Xhosa culture, calling for its abolition is not a solution. It is suggested that the practice rather be redefined to better contribute to the broader challenges of moral regeneration in South Africa.

Abstract:

This study focused on the manner in which a sense of calling - presence and search - is perceived by first- and final-year male and female medical students. Differences in level of calling between first-year students and last-year students were predicted, more so for women than for men due to gender bias and family-work integration challenges. A total of 192 medical first and sixth (last) year students at the five Israeli medical schools filled-out a short self-report measure of calling and recorded demographic factors. Discriminate function analysis resulted in one significant discriminate function weighted positively on presence of calling and negatively on search for calling. Group centroids indicate that male medical students perceived presence of calling and search for calling as two poles of a bipolar continuum, whereas first-year students had a distinct feeling of the presence of calling coupled with a low need to search for calling and final-year students had a low feeling of presence of calling coupled with a distinct need to search for calling. In contrast, female medical students - both first-year and final-year - perceived presence and search as two independent dimensions that can coexist. Understanding these differences may be important in helping medical educators find gender-specific ways to maintain and enhance feelings of calling among tomorrow’s male and female physicians. Key words: gender, medical students, presence of calling, search for calling.

Abstract:

[Types of Speech Acts Following Calling Interjection In Japanese] In speaking, there are times when a calling interjection can be followed by more than one type of speech acts. This research discusses the calling interjection which are used by male speakers in the film Brother Beat. In addition, this study also discussed what kind of speech acts that may follow the call in a speech interjection. The data in this study is a narrative that contains interjection calling spoken by male speakers in the Brother Beat movie. The method used is descriptive qualitative method. To get the data, the researcher usesscrutinize technique and tapping notes method. The results obtained in this research are, calling interjection, such as Anosa, oi, Anona, nee, you, and ano, are often used by male speakers to call the addressees. After the calling interjection, directive speech act and assertive speech act are speech act which appear to follow the calling interjection. Interjection ano sa, oi, anona, and ano, are types of calling interjection which can be followed by a directive speech acts and assertive speech act. In the other hand, calling interjection of nee, can be only followed by a directive speech act, while calling interjection of you can be followed by a ssertives speech act.

Abstract:

AbstractFemales of the white grub beetle, Dasylepida ishigakiensis, release both (R)- and (S)-2-butanol as sex pheromones, but the males are only attracted to (R)-2-butanol. In laboratory-reared females, the proportion of the (R)-isomer decreased significantly as their calling opportunities increased and as they aged. We examined whether such qualitative changes also occur in field populations. We collected virgin females from the field and then trapped and analysed the volatiles emitted during their first and second callings. The ratio of (R)- to (S)-2-butanol (R/S) was 78:22 at the first calling, but shifted to 39:61 at the second calling. While investigating the composition of the female pheromones, the question arose as to whether the male preferences change in response to the shift in female pheromone composition. To answer this question, we observed the behaviour of young and old males in response to various R/S ratios as lures in the laboratory and in the field. In the flight tunnel assay of laboratory-reared individuals, young males touched female models with a 9:1 R/S ratio lure less than those with pure (R)-2-butanol; however, older males touched the two groups with equivalent frequency. In the field trap test, older males were much more attracted to (R)-2-butanol-scented lures. When we tested using lures with the same amount of (R)-2-butanol but added different amounts of the (S)-isomer, we found that increased levels of (S)-2-butanol resulted in lower attractiveness to males. (S)-2-butanol was confirmed to have an inhibitive activity in the attractiveness of (R)-2-butanol.

Abstract:

AbstractFood - calling is a display performed by male fowl during courtship. In a series of experiments with adult male junglefowl, we manipulated food deprivation, variety of food available, sexual experience, familiarity with a female, and familiarity with the environment. We measured the frequency and duration of food - calling to a female during standardized tests, and in some experiments we also measured the distance between male and female. Our results show that all the variables had significant effects on food - calling. We interpret these results to mean that causal factors associated with hunger, sex, and fear/exploration all influence the occurrence of food - calling. Some comparisons of courtship food - calling with parental foodcalling and food - running are discussed with respect to the causation, function, and evolution of these displays.

Abstract:

Abstract Amphibian species require specific conditions for reproduction, such as cover structures and shelters, in both aquatic and terrestrial habitats, which directly influence reproductive success. A careful selection of calling sites is an important process, driving life-history strategies and tactics in amphibians. Despite this, a significant knowledge gap on how different variables modulate amphibian microhabitat selection processes is noted. Thus, we aimed to: (1) describing the microhabitat use of adult neotropical Boana punctata males during the breeding season; and (2) quantitatively analyzing the selection process of five resource variables (i.e., vegetation cover, vegetation density, vegetation height, water depth, and distance to the water shore). We then compared the microhabitat selection of males that achieved spawning and that of males that did not achieve spawning. To quantify selection, we used a resource selection function approach, applying a case/control design where the calling site used by each male was paired to eight surrounding, unused locations. We found that males selected microhabitats with higher vegetation than surrounding areas for reproduction, which suggests territorialism, and selected microhabitats slightly (∼ 30 cm) inside the assessed ponds. Males also acted randomly with regard to the other variables, not influencing the males’ microhabitat selection. Microhabitat use of males successful in obtaining females to spawn was similar to that of males exhibiting mating failure. In addition to being of ecological interest, our study highlights that preserving tall vegetation and the ponds’ shores is important for the conservation of existing B. punctata urban populations.

Abstract:

We studied the response of males to the singing of nearby male conspecifics in two species of the orthopteran genus Cyphoderris, primitive relatives of crickets and katydids. Lone male Cyphoderris buckelli stridulating in a large cage made a phonotactic approach to a nearby speaker broadcasting conspecific calling song. But in field experiments no phonotaxis to song broadcasts occurred; rather, a significant number of male C. buckelli increased their chirp duty cycle and pulse rate. There was no change in their carrier frequency. Calling male Cyphoderris monstrosa were exposed in the field to (i) playback of a synthetic calling song at a typical conspecific pulse rate, (ii) relayed broadcast of their own call, and (iii) low-frequency audio noise. Call duty cycle decreased significantly in response to the noise, while the pooled song models fell just short of significance. Singing C. buckelli were marked individually and their perches flagged over successive nights. We observed low site fidelity and extensive male displacement. Such behaviour is inconsistent with defense of topographically fixed singing territories and concurs with the absence of fighting in this species. Chirp duty cycle was increased significantly in C. buckelli in response to the singing of nearby conspecifics, but unlike in C. monstrosa, this change in duty cycle plays no role in overt aggression, though it may maintain a male's relative attractiveness to females.

Abstract:

AbstractIntensity of male-male competition and sexual selection were studied in the field cricket, Gryllus pennsylvanicus, in an outdoor arena at four sex ratios, male-only (5:0), male-biased (5:2), unity (5:5) and female-biased (5:10). Fighting frequency was highest at male-biased and unity sex ratios. Fighting success was correlated with male body weight at all sex ratios. Calling duration and searching distance decreased with increased female numbers. Opportunity for selection was highest at the male-biased and lowest at the female-biased sex ratio. Selection gradients and differentials were calculated and demonstrated that direct and total selection was highly variable and often relaxed. Direct selection favored male weight at the male-biased sex ratio and total selection for weight occurred at unity. There was no selection on male weight at the female-biased sex ratio. Total and direct selection for increased calling duration occurred at the male-biased sex ratio. Only total selection for calling duration was found at unity, whereas direct selection acted against calling duration at the female-biased sex ratio. Selection did not act on searching at any sex ratio. Natural variations in sex ratios occur and fluctuations in selection on correlated male traits may maintain additive genetic variation for traits important in male-male competition.

Abstract:

AbstractWe address the issue of whether call alternation is a mechanism for diminishing call overlap between male midwife toads who are competing acoustically. Additionally, we study the effect of call overlap on the calling behavior of males and on female preferences. In both species, naturally interacting males emitted calls that did not overlap less than expected when males called randomly. Interactive playback calls showed that males increase their calling rate when responded to by a non-overlapping call, and that they do not increase their calling rate when responded to by calls that overlap with their own calls. In phonotaxis tests, females discriminated against duets of males that overlapped their calls. Furthermore, when calling males overlapped the males' calls, females did not discriminate between the male who was leading a calling duet and the follower. We conclude, therefore, that call overlap plays an important role in communication, since overlapping calls are less attractive to females. However, timing of male calling interactions does not diminish the overlap between calls.

Abstract:

Male sagebrush crickets exhibit differential mating success based on their previous mating experience: virgin males have a higher probability of obtaining a mating than do non-virgin males. Measures of lifetime mating success in male sagebrush crickets have revealed that the median mating frequency is one, with many males failing to secure a mate at all and a small minority obtaining two to four mates. The purpose of this study was to investigate the acoustic and morphological characteristics that make male sagebrush crickets attractive to females. Male crickets were captured from Deadmanâs Bar in Grand Teton National Park and their songs were recorded on subsequent evenings. Five song characteristics were measured including pulse duration, interpulse duration, dominant frequency, train duration, and intertrain duration. Multivariate selection analysis revealed significant linear and nonlinear selection on male song, with each of the five measured song characters contributing to male attractiveness. There was significant directional selection favoring longer pulse durations and shorter interpulse durations, which could be an honest indicator of male quality because these song characters likely impose high energetic costs. Significant stabilizing selection favored males with ~ 13.2 kHz calls and intermediate intertrain durations, which may be imposed by the auditory sensitivity of females.

Abstract:

The intentionality that characterizes human language currently still lacks conclusive evidence for precursors in animal vocal communication. Complex intersubjectivity as in language is usually supposed to be either evolutionary rooted in gestural communication or unique to humans. Here we systematically tested various groups of wild putty-nosed monkeys (Cercopithecus nictitans) for female first-order intentional alarm calling using a recently suggested framework to comparatively test for intentionality in animal communication. Specifically, we used a leopard model to elicit female alarm calls that usually trigger the group’s male alarm calls and further recruit that male to mob and deter the nearby predator. We experimentally disentangled male alarm calling from male predator mobbing to test for female goal directedness in recruiting males for predator defense, voluntary alarm call usage, and the successful manipulation of male behavior. Females monitored male behavior and immediately ceased own alarm calling once the group’s male took over group defense but not after perceiving the male’s typical alarm calls. Unsuccessful male recruitments and the absence of male predator mobbing resulted in persistent and considerably longer female alarm calling. We discuss different communicative functions of female alarms and conclude that our results are most likely explained by the intentional use of female alarms in order to recruit males as ‘hired guns.’

Abstract:

Abstract Male pickerel frogs (Rana palustris) vocalize both above water and underwater. Males have a complex vocal repertoire consisting of an advertisement call and two additional call types (i.e., aggressive calls) that can be elicited by the playback of a conspecific advertisement call. Additionally, in a previous study, males in these playbacks often dove and vocalized underwater for a few minutes before returning to the surface. The purpose of this study was to investigate whether physical or acoustical disturbance cause male pickerel frogs to call underwater. Experimental manipulations were performed with resident males that, initially, were calling above water. In the first, 16 males were physically disturbed with the intent to make them dive underwater. Eleven of these began to call underwater within 10 to 95 seconds and continued for up to four minutes before returning to calling above water. The second experiment involved playbacks in which males were disturbed acoustically by two minutes of continuous advertisement calling from either one Bufo americanus or Pseudacris crucifer male. Only one of 15 males dove and then called underwater in response to B. americanus calls even though most subjects emitted aggressive calls during the test period, and no male called underwater in response to P. crucifer calls (n = 13). In conclusion, male pickerel frogs will shift to underwater calling in response to a physical disturbance, but do not shift in response to the sounds of one heterospecific caller.

AbstractWe investigated changes in calling behavior of individual male Bufo woodhousei in response to playback of natural and synthetic acoustic stimuli. Males lowered their call rates and avoided acoustic overlap with all stimuli centered at 1.4 kHz; only a high frequency (3.8 kHz) stimulus was ineffective. Even filtered noise centered at 1.4 kHz was an effective inhibitor of calling activity. Variation in rate of amplitude modulation of acoustic stimuli had no apparent effect on male calling behavior. These results are discussed in relation to species recognition in bufonids, and acoustic competition between male anurans in general.

Full text

Abstract:

During the breeding season, male harbor seals (Phoca vitulina Linnaeus, 1758) produce underwater calls for sexual advertisement. The daily and seasonal timing of these calls is influenced by female availability (i.e., tidal haul-out patterns, foraging behavior, and oestrus cycle). Therefore, temporal patterns of male calling can provide clues about patterns of female behavior. We collected underwater recordings during the 2014 breeding season at Hornby Island, British Columbia, Canada, and examined the relationships of light level, progression of breeding season, and tide relative to call presence or absence and calling rate. Calls were 15 times more likely to occur at night than during the day. Nocturnal peaks in calling rate have been observed in other harbor seal populations and have been attributed to tidal haul-out patterns and nocturnal foraging of females. In this study, tide level did not have a significant effect on calling rate, and female foraging behavior was not monitored. One acoustic observation of mammal-eating killer whale (Orcinus orca (Linnaeus, 1758)) calls was followed by 48 h of decreased calling rate. We infer that predation risk influences the temporal pattern of male calling at this location and suggest further study to support this hypothesis.

Abstract:

AbstractChorusing male anurans typically spend only a part of the breeding season calling although chorus tenure is often the best predictor of mating success. We determined the number of nights males attended a chorus (chorus tenure) and its influence on mating success in the European tree frog, Hyla arborea. The median chorus tenure was 7.5 nights out of a study season of 38 nights. Males that spent more than two nights in the chorus were present for an average of 47% of the nights between their first and last night in the chorus. Minimum daily temperature, ambient temperature at initiation of calling, and daily rainfall explained 37.8% of the variance in male attendance. Twenty-five males were calling on the night of peak activity, a fraction of the 44 males marked. This suggests that estimates of male population size based on peak activity, widely used by conservation biologists, are inaccurate. We suggest that, when mark-recapture methods cannot be used, male population size be calculated by using a regression model based on the peak number of calling males that can be further developed as more data accumulates.

Abstract:

BackgroundThe evolution of exaggerated vocal signals in anuran species is an important topic. Males and females have both evolved the ability to discriminate communication sounds. However, the nature of sexual dimorphism in cognition and sensory discrimination and in the evolution and limitation of sexual signal exaggeration remain relatively unexplored.MethodsIn the present study, we used male calls of varied complexity in the serrate-legged small treefrog,Kurixalus odontotarsus, as probes to investigate how both sexes respond to variations in call complexity and how sex differences in signal discrimination play a role in the evolution of sexual signal exaggeration. The compound calls of maleK. odontotarsusconsist of a series of one or more harmonic notes (A notes) which may be followed by one or more short broadband notes (B notes).ResultsMale playback experiments and female phonotaxis tests showed that increasing the number of A notes in stimulus calls elicits increased numbers of response calls by males and increases the attractiveness of the stimulus calls to females. The addition of B notes, however, reduces male calling responses. Moreover, call stimuli which contain only B notes suppress spontaneous male calling responses. Phonotaxis experiments show that females prefer calls with greater numbers of A notes and calls containing both A notes and B notes, but do not prefer calls with only B notes.DiscussionMale-male competition and female choice appear to have played different roles in the evolution and limitation of signal complexity inK. odontotarsus. These results provide new insights into how exaggerated compound signals evolve and how signal complexity may be limited in anurans.

Abstract:

Vestigial morphological traits are common and well known in a variety of taxa. Identification of vestigial genes has illustrated the potential for evolutionary reversals and the re-expression of atavistic traits. Here we induce expression of a behavioural sexual signal, male calling song, in a cricket species, Gryllus ovisopis, which lacks a functional calling song. We successfully used acetylcholine injections in the frontal space of the head of male crickets to activate cerebral command neurons for cricket calling, and we recorded calling songs with a temporal chirp pattern similar to that of G. ovisopis ' close evolutionary relatives, G. firmus and G. pennsylvanicus , implying that the neural pattern generators that underlie cricket calling behaviour persist in a vestigial state in G. ovisopis . To our knowledge, this is the first demonstration of the induced expression of a vestigial behaviour in any organism. The retention of latent neural capacity to express sexual behaviours could have important implications for rapid evolution, trait re-emergence and reproductive isolation.

Abstract:

Bioacoustics is an effective way of recording detailed data during population surveys and monitoring. In the present study, we used an automated digital recorder (ADR) to describe the temporal variation in the calling activity of Scinax fuscomarginatus (Lutz, 1925) in central Brazil. We also evaluated the role of climatic variables (air temperature and precipitation) on calling activity by using a Generalized Additive Model (GAM). We conducted the recordings at five ponds in the Cerrado savanna of Rio Verde Municipality, in Goiás state between November 2013 and October 2014. The analysis of the 43.2 hours of acoustic recording showed that S. fuscomarginatus has a prolonged breeding pattern. The ADR provides a fine-scale description of the nocturnal calling pattern, as well as the oscillations between the rainy and dry seasons. The results of the analytical model also indicate that calling patterns were related to minimum (but not maximum) air temperatures and precipitation, which may be related to their reproductive and thermoregulatory requirements. Based on these findings, we conclude that the ADR method has potentially valuable applications for the collection of data on the natural history of anuran species, as well as supplying important insights for conservation initiatives.

Abstract:

The morphology and pair-forming acoustic signals of Isophya sicula sp. n., a new phaneropterine bush-cricket species from the Eastern Carpathians (Romania) is described. The species is morphologically similar to I. posthumoidalis and I. camptoxypha, but the male calling song differs clearly from the songs of those species. The male calling song is a long series of evenly repeated, very short syllables. Syllables are much shorter than in I. camptoxypha, and the song is composed from only one syllable type differently from I. posthumoidalis, where the male calling song is composed of two syllable types. Pair formation is achieved during an acoustic duet. The delay of female response (40–70 ms) is shorter than in I. camptoxypha and I. posthumoidalis. Basic descriptive statistics of sonometric and morphometric characters of the new species as well as SEM photos of the male stridulatory file and female stridulatory bristles are presented.

Abstract:

AbstractWe studied the calling behavior of male mink frogs, Rana septentrionalis, and how their calling activity varied through nightly calling periods. We observed focal males during their summer breeding season for 1 h periods during chorus activity, which extends from midnight until 0900h, and recorded call types and rates. During this period, male R. septentrionalis produced a repertoire of single and multi-note calls composed of one or two note types, referred to as cuk and rumble notes. Calls that included series of both note types were most frequent between 0100 and 0330h, while single cuks were primarily produced early and late in the chorus period. Call rate peaked between 0200h and 0300h, declined until dawn, then increased until 0900h. Call properties were analyzed from recordings of male vocalizations; temporal properties, such as call and note duration, were the most variable, both within and among males, whereas spectral properties, such as dominant frequency, varied the least. In general, males produced the most complex and variable calls during a peak period of calling activity.

Abstract:

AbstractThe present study was performed to examine why female Burmese red junglefowl (Gallus gallus spadiceus) approach a food-calling male. Females from three small groups were tested individually with a male under different conditions. Deprivation of food for 24 h did not affect the reaction of females to food-calling, showing that the feeding system is not crucially involved. This result makes it unlikely that courtship food-calling with inedible objects is a case of deception, as was suggested previously. Further it was shown that females willing to perform the sexual crouch and females low in the peck-order were more likely to approach food-calling. These factors were found to be interrelated and fear was suggested to play a crucial role both in inhibiting and modulating approach and in willingness to crouch. The data gathered on the involvement of the sexual system did not allow for any definite conclusions, but as an alternative it was suggested that females might approach courtship food-calling because it arouses curiosity, or, exploration.

Abstract:

AbstractOxygen consumption of calling male spring peepers (Pseudacris crucifer) was measured at five temperatures (7, 10, 15, 19, and 23°C) encompassing the natural range of variation encountered during the breeding season. Oxygen consumption increased as a linear function of calling rate, which in turn was a linear function of temperature. Hence, nearly all the increased cost of calling at warmer temperatures was accounted for by increases in calling rate; temperature did not appear to have any independent effect on activity metabolism. During one breeding season, ambient temperature increased throughout the season, resulting in an hourly cost of calling at the end of the season that was double the cost at the beginning. Periodic warm spells also resulted in major increases in the cost of calling.

Abstract:

Genetic and environmental sources of variation in the temporal patterning of song structure may be important variables influencing male field cricket reproductive success. Song structure in both field and laboratory populations of Gryllus pennsylvanicus was examined to assess possible sources of variation. Factors examined included temperature, male age, body mass, time of day, and male spacing patterns. Temperature was positively correlated with pulse rate and negatively correlated with interchirp interval for both field and laboratory populations. Temperature was negatively correlated with chirp duration only in the field population. Calling song structure did not vary with male age or mass. Time of day had a significant effect on the song parameters examined, even when data were corrected for temperature differences. Males calling in the morning had faster pulse rates and shorter chirp durations than males recorded at night time. Male spacing patterns also influenced calling; isolated males had longer intervals between consecutive chirps than clumped males. Data are discussed in terms of acoustical competition between males and female choice.

Abstract:

Field crickets are extensively used as a model organism to study female phonotactic walking behaviour, i.e. their attraction to the male calling song. Laboratory-based phonotaxis experiments generally rely on arena or trackball-based settings; however, no attention has been paid to the effect of substrate texture on the response. Here, we tested phonotaxis in female Gryllus bimaculatus , walking on trackballs machined from methyl-methacrylate foam with different cell sizes. Surface height variations of the trackballs, due to the cellular composition of the material, were measured with profilometry and characterized as smooth, medium or rough, with roughness amplitudes of 7.3, 16 and 180 µm. Female phonotaxis was best on a rough and medium trackball surface, a smooth surface resulted in a significant lower phonotactic response. Claws of the cricket foot were crucial for effective walking. Females insert their claws into the surface pores to allow mechanical interlocking with the substrate texture and a high degree of attachment, which cannot be established on smooth surfaces. These findings provide insight to the biomechanical basis of insect walking and may inform behavioural studies that the surface texture on which walking insects are tested is crucial for the resulting behavioural response.
