  • Activity budgets and behavioural synchrony in a wild equid living in a
           fission-fusion social system (Advance Article)
    • Authors: Antoine St-Louis; Steeve D. Côté
      Abstract: Source: Page Count 20Variation in activity budgets among individuals of different age-sex classes and reproductive status may lead to decreases in behavioural synchrony (i.e., individuals performing the same behaviour at the same time in the same group) in social species. Here, we assessed the costs of behavioural synchrony in terms of time allocated to feeding behaviour among individuals of different age-sex classes and reproductive status in the kiang (Equus kiang), a poorly known wild equid that inhabits the Tibetan Plateau. Our study was conducted in Eastern Ladakh (India), during summer and fall. Our results showed that groups were highly synchronized, and that individuals in groups were particularly synchronized when feeding. Despite a slight sexual dimorphism, males and females had similar activity budgets. Males in groups, however, spent less time feeding than solitary males, and females in groups with foals spent less time feeding and more time standing than females in groups without foals. We suggest that group formation in males and the presence of foals for females incur behavioural costs by lowering their time spent feeding. Because these costs occur at a predictable time of the year, it could be profitable for adult kiangs not to form permanent groups year-round. Individuals with divergent needs might benefit from the loose social system observed in kiangs, which could be a key feature of their adaptation to a highly seasonal environment.

  • Alarm cue specificity and response ontogeny in juvenile rainbow trout ()
    • Authors: Marianna E. Horn; Douglas P. Chivers
      Abstract: Source: Page Count 9Many aquatic prey animals release chemical cues upon being captured by a predator. These chemical cues, referred to as alarm cues, may act to warn nearby individuals of danger. For the cues to be useful, fish must be able to discern if they are indicative of a real threat; cues from conspecifics in different age groups may be irrelevant due to size- and habitat-related shifts in predation risk. We test the response of newly-hatched rainbow trout, Oncorhynchus mykiss, to three concentrations of alarm cues from conspecifics from two age groups: newly-hatched versus six-month-old juveniles. Newly-hatched trout demonstrated a significant fright response to all three concentrations of alarm cues, but showed no difference in strength of response based on either concentration or age of the cue donor. We propose that the newly-hatched trout did not respond differently because of the high risk of predation that they face during this life stage.

  • Is it one call or two? Perception of inter-pulse and inter-call
           intervals in the grey treefrog,
    • Authors: Joshua J. Schwartz; Ridwan Hossain
      Abstract: Source: Page Count 20Female grey treefrogs, Hyla versicolor, treat a call with an anomalously large gap between call pulses as relatively unattractive. However, whether such a ‘call’ is treated (or perhaps perceived) as a single call or two separate calls, an issue relevant to the problem of perceptual segregation of calls of different males, was unclear. We tested whether there could be gaps shorter than a typical inter-call interval that would be sufficient to elicit the latter percept by offering females a choice between a 5-pulse call and 13-pulse call separated by a 1575-ms gap and these pulse strings separated by shorter gaps. Preliminary results suggested that perception of inter-call gaps was categorical, and the distributions of such gaps between males in choruses were compatible with this finding. However, when we also offered females call alternatives designed to specifically test the hypothesis of categorical perception, predictions were only sometimes met.

  • Simulated maternal care facilitates the formation of filial imprinting in
           domestic chicks (Advance Article)
    • Authors: Félix Junco
      Abstract: Source: Page Count 24The potential effects of maternal care-related stimuli on imprinting in domestic chicks were examined. In the first phase, one group of chicks received a simulated brooding experience with a primary imprinting object during two training sessions, whereas chicks in another group received exposure to the object without being brooded. In subsequent testing, the brooded chicks showed a robust preference for the primary imprinting object, whereas the non-brooded chicks showed a weaker preference for the object. In the second phase, one group of chicks was exposed to a secondary imprinting object associated with a feeding opportunity, whereas another group received exposure to the object in the absence of such an experience. In subsequent testing, the fed chicks showed a strong preference for the secondary imprinting object, whereas the non-fed chicks showed no preference. These results suggest that stimuli experienced through usual maternal care may be an important factor in filial imprinting.

  • Information depends on context: behavioural response to chemical signals
           depends on sex and size in crayfish contests
    • Authors: Sarah J. Wofford; Phillip M. LaPlante Paul A. Moore
      Abstract: Source: Page Count 26Securing information about oneself or an opponent can be crucial to update the likelihood of winning a contest and the relative costs of continuing or escalating. This information can subsequently reduce costly errors. However, information encoded in signals exchanged by opponents can differ based on context. We sought to unravel these differences by pairing male and female crayfish (Orconectes rusticus) under varying sex and size conditions. A pre-optimized technique was used to visualize a well-studied contest signal in crayfish (i.e., urine). Behavioural responses were quantified prior to and after the release of that signal. There was a characteristic de-escalation of behavioural intensity after an opponent released urine. However, behavioural changes after the release event were dependent on the sex and the relative size of the opponents. Urine also significantly altered both sender and receiver behaviour, but lack of behavioural differences suggests urine plays a role in both opponent and auto-communication.

  • Isolation call ontogeny in bat pups ()
    • Authors: Sina Engler; Andreas Rose Mirjam Knörnschild
      Abstract: Source: Page Count 20Bat pups produce isolation calls to solicit maternal care. During maturation, pup isolation calls may gradually develop into echolocation calls or exist in parallel to them, depending on the species involved. We studied the ontogeny of isolation calls in nectivorous bats, Glossophaga soricina. Isolation calls of G. soricina pups were frequency modulated calls uttered in bouts of varying length. Newborn pups already produced both isolation calls and echolocation call precursors (which developed into ‘normal’ echolocation calls), indicating that isolation calls of G. soricina pups occur independently and exist in parallel to echolocation calls during ontogeny. We found strong statistical evidence for an individual signature encoded in isolation calls. Moreover, we provide evidence for considerable changes in isolation call parameters over a short ontogenetic time span. Throughout ontogeny, the call interval decreased significantly whereas most frequency parameters increased significantly and call entropy rose (i.e., isolation calls became less tonal but noisier).

  • Time partitioning in mesocarnivore communities from different habitats of
           NW Italy: insights into martens’ competitive abilities (Advance
    • Authors: E. Torretta; A. Mosini, M. Piana, P. Tirozzi, M. Serafini, F. Puopolo, N. Saino A. Balestrieri
      Abstract: Source: Page Count 26Most studies focused on species coexistence have been directed at the differential use of habitat and food resources; nonetheless, the differential use of the diel cycle may enhance the coexistence of same-sized species. We investigated the activity patterns of mesocarnivores (red fox (Vulpes vulpes), European badger (Meles meles), pine marten (Martes martes), stone marten (M. foina)) in NW Italy via camera-trapping. We hypothesized that the smallest species would tend to avoid competition by selecting time periods when larger species were less active. Foxes, badgers, and stone martens were mainly nocturnal. In lowland areas overlap between coexisting species was generally low, while in Mediterranean habitats all activity patterns tended to be unimodal and overlap was generally high. The pine marten showed a cathemeral pattern. We suggest that the lower ability of the stone marten to avoid interference competition at community-level may play a major role in determining its widespread exclusion from forested areas by the pine marten.

  • The sensory ecology of prey detection in the bat-eared fox ()
    • Authors: S. Renda; A. le Roux
      Abstract: Source: Page Count 14In the absence of direct sunlight, nocturnal animals face sensory challenges different to those affecting their diurnal counterparts whilst foraging. Anecdotal observations have led to the general prediction that the auditory sensory mode is the most prominent for the bat-eared fox (Otocyon megalotis), a nocturnal, insectivorous canid. The present study aimed to clarify the relative importance of different sensory modes to foraging bat-eared foxes by conducting sensory trials with individuals belonging to a habituated population in the Kuruman River Reserve in South Africa. Foxes were tested in repeated trials controlling for particular sensory stimuli using live or pre-killed prey. Auditory cues proved significant (p⩽0.01) predictors of fox foraging success with olfactory and visual cues indicated as being of secondary importance. This study thus provides empirical confirmation for anecdotal reports that the bat-eared fox is predominantly reliant on auditory cues to determine hunting success.

  • Impact of personality traits and early life experience on timing of
           emigration and rise to alpha male status for wild male white-faced
           capuchin monkeys () at Lomas Barbudal Biological Reserve, Costa Rica
    • Authors: Susan Perry; Irene Godoy, Wiebke Lammers Andy Lin
      Abstract: Source: Page Count 32It is rare in studies of long-lived animals to know enough about the personalities and early experiences of individuals to use this information to predict their behaviour during major life transitions in adolescence and adulthood. Here, we examine how personality traits and early experiences predict age of natal emigration and timing of first ascent to alpha status in 169 wild male white-faced capuchins studied at Lomas Barbudal, Costa Rica, 75 of whom emigrated and 23 of whom acquired alpha status. Males were more likely to delay natal emigration if they were more extraverted, more neurotic, if their fathers co-resided longer with them, and if there were fewer alpha male turnovers. More extraverted males attained alpha status sooner.

  • Social complexity and cultural transmission of dialects in killer whales
           (Advance Article)
    • Authors: Olga A. Filatova; Tatiana V. Ivkovich, Mikhail A. Guzeev, Alexandr M. Burdin Erich Hoyt
      Abstract: Source: Page Count 24Many social animals have cultural traditions that may shape their societies while the social structure can in turn influence how the culture is acquired. Killer whales possess culturally transmitted dialects. The divergence of dialects was thought to occur simultaneously and consistently with the gradual fission of matrilines. In this paper we compare the social associations across matrilineal units, Bayesian phylogeny of dialects and similarity of particular syllables to test whether dialects affect social structure and whether associations or common origin define similarity of call types. We found that neither phylogeny of dialects nor similarity of syllables was correlated to associations between matrilineal units, but similarity of syllables was correlated to phylogeny of dialects for four of the six syllables analysed. The complexity and fluidity of social ties between matrilineal units and the variation in cultural transmission patterns produce a complex relationship between the social network and the socially learned vocalizations.

  • Aggressive defence of food by precocial chicks varies with its
           concentration in space
    • Authors: Reyna Hernández-Reyes; Cristina Rodríguez Hugh Drummond
      Abstract: Source: Page Count 8In juvenile and adult animals, including mammals, birds, fishes and a crustacean, competition for food becomes increasingly aggressive as its spatial concentration increases. This ecological relationship has not been investigated in infant animals, although it is thought that broods of precocial chicks of some avian species compete aggressively for food or status in a brood hierarchy. When pairs of common quail broodmates were offered the same amount of ground corn in four spatial concentrations between ages 15 and 59 days, aggression increased progressively with concentration, culminating in an overall 16-fold increase when corn was in a single clump. These results suggest that aggressive defence may increase with spatial concentration of food in precocial chicks generally, and raise the possibility that a similar pattern could occur in some altricial chicks during the transition to independence and in infants of other animal species.

  • Chemical cues influence retreat-site selection by flat rock spiders
    • Authors: Scott Penfold; Buddhi Dayananda Jonathan K. Webb
      Abstract: Source: Page Count 13Many animals use chemical cues to detect conspecifics and predators. On sandstone outcrops, flat rock spiders Morebilus plagusius and Polyrachis ants use sun-exposed rocks as nest sites, and defend rocks from intruders. We investigated whether chemical cues influenced retreat-site selection by spiders. In the field, spiders showed significant avoidance of rocks used by ants. In laboratory trials, we gave spiders the choice between conspecific-scented and unscented refuges, and ant-scented and unscented refuges. In conspecific scent trials, spiders showed no avoidance of spider scented refuges during the night, but significantly more spiders chose unscented refuges as their diurnal retreat-site. In ant scent trials, spiders made more visits to unscented refuges than ant-scented refuges during the night, and significantly more spiders chose unscented refuges as their diurnal retreat site. Our results demonstrate that spiders can detect chemical cues from ants and conspecifics, and that such cues influence retreat-site selection.

  • Assessing anti-predator decisions of foraging eastern chipmunks under
           varying perceived risks: the effects of physical and social environments
           on vigilance (Advance Article)
    • Authors: Jeanne Clermont; Charline Couchoux, Dany Garant Denis Réale
      Abstract: Source: Page Count 18Animals foraging under risk have to trade-off resource acquisition and predator avoidance. Environmental factors can modulate the level of risk and should thus influence the expression of anti-predator behaviours such as vigilance. In this study, we investigated the effects of physical and social environments on eastern chipmunks’ (Tamias striatus) vigilance, by varying the perceived risk through playback experiments of alarm calls and neutral environmental sounds, and by integrating habitat and weather characteristics, as well as neighbour density. Chipmunks showed higher levels of vigilance when foraging in more open habitats, under high wind conditions, when they heard alarm calls and when surrounded by a high neighbour density. The effects of wind intensity and neighbour density on vigilance were also stronger during the broadcast of alarm calls rather than neutral sounds. Our results emphasize how both the physical and social environments can modify risk perception and therefore risk-taking decisions of foraging individuals.

  • The role of male coloration in the outcome of staged contests in the
           European common wall lizard () (Advance Article)
    • Authors: J. Abalos; G. Pérez i de Lanuza, P. Carazo E. Font
      Abstract: Source: Page Count 25Colour signals play a key role in regulating the intensity and outcome of animal contests. Males of the common wall lizard (Podarcis muralis) show conspicuous ventrolateral ultraviolet (UV)-blue and black patches. In addition, some populations express a striking ventral colour polymorphism (i.e., discrete orange, white and yellow morphs). In this study, we set out to evaluate the potential signalling function of these colour patches by staging pairwise combats between 60 size-matched adult lizards (20 per morph). Combats were held in a neutral arena, with each lizard facing rivals from the three morphs in a tournament with a balanced design. We then calculated a fighting ability ranking using the Bradley–Terry model, and used it to explore whether ventral colour morph, the size of UV-blue and black patches or the spectral characteristics of UV-blue patches (i.e., brightness, hue, chroma) are good predictors of fighting ability. We did not find an effect of the UV-blue patches on contest outcome, but the size of black patches emerged as a good predictor of fighting ability. We also found that winners were more aggressive when facing rivals with black patches of similar size, suggesting that black patches play a role in rival assessment and fighting rules. Finally, we found that orange males lost fights against heteromorphic males more often than yellow or white males. In light of these results, we discuss the potential signalling function of ventrolateral and ventral colour patches in mediating agonistic encounters in this species.

  • Iridescent blue and orange components contribute to the recognition of a
           multicomponent warning signal

      Abstract: Source: pp 1 - 16Warning colouration functions to deter predators from attacking unprofitable (e.g., unpalatable or toxic) prey items. While warning colours are often characterized by long-wavelength components (e.g., orange, red or yellow), many distasteful animals across the animal kingdom display orange or red colour patches adjacent to or within a field of short-wavelength colouration such as blue (e.g., strawberry poison dart frogs, pipevine swallowtail and pyjama nudibranch), which yields a multicomponent visual warning signal. Here we show that, in such signals, blue and orange patches can function as redundant signal components; avian predators trained not to attack the intact blue and orange colouration of the pipevine swallowtail (Battus philenor) recognised the butterflies as distasteful even when the blue and orange were presented individually. Our results demonstrate that blue colouration and potential multiple, unimodal, signal components should be considered in research on visual warning signals, including in well-studied animals, such as dendrobatid frogs and swallowtail butterflies.
