“…This study adds to a growing number of studies in frogs (reviewed in Bee 2016; Bee et al 2016) and other animals (reviewed in Temeles 1994) demonstrating variation in neighbor recognition and the dear enemy effect among territorial species. Vocally-mediated neighbor recognition has been demonstrated in two frog species in the family Ranidae (Davis 1987;Bee and Gerhardt 2002;Chuang et al 2017), but studies of some other distantly related frog species, including other poison frogs (Bee 2003;Tumulty et al 2018), have failed to find robust evidence that territory holders recognize neighbors and behaviorally discriminate between the calls of neighbors and strangers (Bee 2016;Bee et al 2016). The difference in neighbor recognition and the dear enemy effect between closely related species shown here highlights that this behavior is evolutionarily labile.…”

“…This is because even though Kai rocket frogs share territory boundaries with neighbors for shorter durations than golden rocket frogs, they still defend territories for at least several weeks, which is should provide ample opportunity for males to learn their neighbors' calls. For example, male bullfrogs (Howard 1978) and olive frogs (Chuang et al 2013) also defend territories for several weeks during the breeding season, and both of these species exhibit neighbor recognition and the dear enemy effect (Davis 1987;Chuang et al 2017).…”

Navigating social relationships frequently rests on the ability to recognize familiar individuals using phenotypic characteristics. Across diverse taxa, animals vary in their capacities for social recognition but the ecological and social sources of selection for recognition are often unclear. In a comparative study of two closely related species of poison frogs, we identified a species difference in social recognition of territory neighbors and investigated potential sources of selection underlying this difference. In response to acoustic playbacks, male golden rocket frogs (Anomaloglossus beebei) recognized the calls of neighbors and displayed a "dear enemy effect" by responding less aggressively to neighbors' calls than strangers' calls. In contrast, male Kai rocket frogs (Anomaloglossus kaiei) were equally aggressive to the calls of neighbors and strangers. This species difference in behavior was associated with key differences in reproductive ecology and characteristics of territories. Golden rocket frogs defended reproductive resources in the form of bromeliads, which is expected to create a threat asymmetry between neighbors and strangers favoring decreased aggression to neighbors. In contrast, Kai rocket frogs did not defend reproductive resources. Further, compared with Kai rocket frog territories, golden rocket frog territories occurred at higher densities and were defended for longer periods of time, creating a more complex social environment with more opportunities for repeated but unnecessary aggression between neighbors, which should favor the ability to recognize and exhibit less aggression towards neighbors. These results suggest that differences in reproductive ecology can drive changes in social structure that select for social recognition.

“…In Matheran, usually temperature during the breeding season varies from 22.4 to 24.4°C (a variation of 2°C). Consequently, less fluctuation in the prevailing temperature could be responsible for the lack of correlation between temperature and acoustic properties of N. humayuni as suggested (Chaung et al, ).…”

“…By virtue of being ectothermic, calling behaviour and acoustic properties of male anurans are affected by environmental factors such as rainfall and temperature (Gerhardt & Huber, ). For instance, fundamental frequency, call rise time, pulse repetition, amplitude and frequency modulation were correlated with temperature (An & Waldman, ; Bee et al, ; Chaung, Kam, & Bee, ). In the present study, however, none of the call properties of N. humayuni was correlated with temperature.…”

In anurans, vocalisation is used to communicate within and between the sexes during reproduction. Knowledge of vocal repertoire and its diversity is essential in understanding its significance in sexual selection. In this context, we studied the vocal behaviour of Nyctibatrachus humayuni and quantified the urinary metabolites of androgens and corticosterone to understand the associations among hormones, body condition index and vocalisation. Our results show that males of N. humayuni produce an amplitude‐modulated call consisting of a train of pulses. Interestingly, a high degree of inter‐individual variation was observed in the call parameters. The dominant frequency and pulse interval were negatively correlated with male body size, whereas pulse duration and pulse duty cycle were positively correlated with it. Dominant frequency was negatively correlated with androgens and corticosterone, whereas pulse interval was negatively correlated with corticosterone. Further, pulse duty cycle, pulse duration and pulses per call were positively associated with corticosterone. Surprisingly, none of the acoustic parameters was associated with male body temperature and body condition. A significant variation was evident in the vocal effort, dominant frequency and amplitude of advertisement calls produced under different social situations. Calls produced during territory establishment had lower dominant frequency but higher vocal effort, whereas those produced during courtship had higher amplitude and vocal effort than the calls produced in the absence of a competitor/female. Our results suggest that greater inter‐male variability in the advertisement call of N. humayuni could be important in female choice as it may help females to assess the quality of a male. Further, androgens and corticosterone could be important in modulating crucial parameters of the advertisement call.

But reduced aggression, for instance, via dear-enemy effects (Temeles 1994), can likewise be an important benefit of maintaining long-term social bonds, especially in territorial animals (Jaeger 1981; Chuang, Kam & Bee 2017; Siracusa et al . 2019).…”

24 25 1. Social bonds can have important fitness consequences. Although there is increasing 26 evidence that social bonds carry over across contexts, few studies have investigated 27 whether social bonds formed early in life are carried over to adulthood. For example, 28 juveniles of monogamous species go through a major life-history stage transition-pair 29 formation-during which the pair bond becomes a central unit of the social organization. 30 At present, it remains unclear if pair members retain their early-life social bonds after 31pair formation and, if so, when they display these preferences most strongly. 32 2. Here we investigated whether bonds formed early in life carry over into adulthood and 33 whether carry-over was dependent on season, in a monogamous species. Moreover, we 34 investigated the role of familiarity, genetic relatedness and aggression on the 35 perseverance of social bonds. 36 3. We studied the social structure before and after pair formation in captive barnacle geese 37 (Branta leucopsis), a highly social, long-lived, monogamous species. We constructed 38 social networks of groups of geese before pair formation, during the subsequent breeding 39 season, and in the following wintering season. From these networks, we identified the 40 preferred associations among individuals, and how these are carried over during seasonal 41 changes. 42 4. We found that early-life associations in females were lost during the breeding season, 43 but resurfaced during the subsequent wintering season. In males, the early-life 44 associations persisted across both seasons, and were mediated by genetic relatedness and 45 familiarity. The high level of aggressiveness of males, but not females, in the breeding 46 season suggests that males may have played a key role in shaping both their own social 47 environment and that of their female partners. 48 3 5. By taking advantage of a captive population in which animals had no temporal or spatial 49 restrictions to re-associate after pairing and for which we had complete data on their 50 social history, we show that early-life social relationships can be maintained well into 51 later life. Such bonds can be sustained even if they are temporarily disrupted, for example 52 due to reproductive behaviour. Our findings therefore highlight that the early-life social 53 environment can have life-long consequences on individuals' social environment. 54 55 Key-words: aggression, early life, familiarity, genetic relatedness, monogamous, pair 56 formation, social bonds, social networks 57 58 59 Consistency of social bonds affects the extent to which individuals can develop cooperative 60 interactions, build up reputations and form stable dominance hierarchies (Trivers 1971; Axelrod . There is increasing evidence showing that social bonds 65 carry over across time, place, and context. Shizuka et al. (2014) showed that golden-crowned 66 sparrows (Zonotrichia atricapilla) that flocked together in one winter flocked together in the 67 subsequent winter more often than expected ba...
