Many ungulate species live in large gregarious groups, where there is potential to obtain vital information from conspecifics. However, there is a lack of data concerning the cognitive processes involved in social learning in the ungulates. This study focuses on a domestic species, the goat, <em>Capra hircus</em>, and tests whether they are capable of using social information to solve a foraging problem and if successive transmissions can corrupt information. We used a diffusion-chain paradigm, in which an individual can learn by observing a single trained model and subsequently become a model for the following individual in the chain. We used a puzzle box that could be opened using two different techniques. A majority of goats were able to use the same technique that they saw performed by a conspecific, with a positive association between opening success and rate of observation of the model. Unsuccessful goats also made more attempts to open the box with the technique previously used by the model. This is the first evidence of horizontal diffusion for a new foraging technique in goats. As dispersed foragers, goats may be efficient at monitoring the foraging activities of their conspecifics.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123082"},"PeriodicalIF":2.3,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we first trained dogs to learn correct responses in a two-choice task using a compound stimulus consisting of social (human pointing) and nonsocial stimuli (printed figures on paper) as cues. Social and nonsocial stimuli were presented alone to examine whether the social stimulus overshadowed the nonsocial stimulus. We also examined the correlation between temperament scores (based on the Canine Behavioral Assessment &amp; Research Questionnaire, C-BARQ) and task performance. The results showed that social stimuli overshadowed nonsocial stimuli in most dogs, indicating that dogs used social stimuli from humans more frequently than nonsocial stimuli. Strong positive correlations were observed between attachment scores from the C-BARQ and correct response rates to nonsocial stimuli, but there was no correlation between aggression/fear and correct response rates to social stimuli. We considered that positive correlations between attachment scores and correct response rates to nonsocial stimuli indicate the degree of individual attentiveness to various environmental stimuli, and that responses to human pointing are likely to be reinforced from an early age. In addition, individual fear and aggression and social cognitive abilities can vary separately.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123099"},"PeriodicalIF":2.3,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying how nonhuman animals respond to music can contribute to a better understanding of the effect of sound on animals. Animals are frequently exposed to human music, whether intentionally (for example, in laboratory settings), or unintentionally (for example, when animals live in close proximity to humans). Although several papers examine animals' responses to music, these typically do so from a purely animal behavioural perspective, sometimes missing relevant details about salient features of the music being played. An interdisciplinary approach that places musical and scientific knowledge on equal footing can improve our understanding of how animals respond to music and music-like sounds, in new and exciting ways. Here, we show with a systematic review that crucial factors (intrinsic music properties, listener properties, playback context and producer properties and contexts; ILPP) are not being adequately considered or reported in recently published scientific articles on the effects of music on animals, which hinders scientific reproducibility within this area of study. These problems are caused by improper referencing of music sources, misunderstanding of music and unexamined assumptions about individual variation and preferences between individuals of the same or different species. We then suggest that Berlyne’s psychobiological theory might provide a useful framework for studying how animals respond to human-generated sounds.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123074"},"PeriodicalIF":2.3,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143096749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies, particularly in birds and mammals, show that parents modulate their response to these signals according to characteristics such as their intensity and number per unit of time. In crocodilians, mature embryos still in the egg emit hatching calls perceived by other embryos and by the adult guarding the nest. These calls help to synchronize hatching within the nest and encourage the adult to dig the nest and help the young to hatch. However, the embryos do not start calling all at once, and it can take several hours or even days after embryos have started to vocalize before the adult digs the nest. When and why does the crocodile parent decide to respond to the hatching calls of its offspring? Here we show that Nile crocodile, <em>Crocodylus niloticus</em>, mothers only start digging their nests if the hatching calls are emitted in a sustained manner by the offspring. While females react with head and body orientation movements to isolated calls, only continuous bursts of calls lasting several tens of seconds induce digging behaviour. This high response threshold on the part of the mothers probably limits the untimely digging up of eggs that may not have reached full maturity, thus avoiding damaging them, and is likely to favour the synchronization of offspring hatching. Overall, this study suggests that the parental response of Nile crocodiles to offspring solicitations is not necessarily linearly correlated with the number of begging signals received but may require a sufficient number of begging signals to exceed a threshold.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"220 ","pages":"Article 123040"},"PeriodicalIF":2.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prey animals can thus adjust their own activity rhythm to avoid the most dangerous periods. We studied this situation in a coevolutionary perspective, considering that, if prey spread their activity across the day to counter predator temporal preferences, these preferences may in turn change to track prey activity. We therefore built a game-theoretical model to derive evolutionarily stable activity patterns for a predator constantly trying to maximize its chance of capture and a prey trying to minimize this probability. Key parameters concern circadian variations in environmental conditions and their influence on predator hunting efficiency and energy demands of the prey, which dictate its total amount of activity. The model predicts high levels of prey activity during periods of reduced predator efficiency. The predator may then either track these activity peaks and copy the activity patterns of its prey, or concentrate its hunting effort during periods when prey activity is low but conditions favour hunting. In the first case, predator and prey activity patterns will be synchronized. In the second one, they will exhibit strong temporal segregation. We show how these diverging scenarios emerge and how they can help to disentangle the wide variety of situations existing in the wild.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"221 ","pages":"Article 123078"},"PeriodicalIF":2.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143480431","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

House mice, <em>Mus musculus</em>, are intensively studied; however, little is known about their vocalizations emitted during courtship sequences and whether and/or how they influence male copulatory success. To address these questions, we recorded the behaviour and vocalizations of pairs of wild house mice across distinct phases of courtship and mating. Over 53 000 vocalizations were detected and classified, and of these ca. 90% were ultrasonic (USV) and 10% were broadband (BBV) vocalizations, presumably emitted by males and females, respectively. Mice altered their vocal rate, composition and repertoire at each stage of courtship and mating. They increased the emissions of all simple USVs while reducing other calls upon contact with a potential mate. Then, once males began mounting and engaging in other sexual interactions, the pairs emitted more complex calls, especially harmonic USVs and BBVs with spectral nonlinearities. Vocalizations were closely associated with male mating behaviour and peaked in rates and complexity just before males approached the female to mount. USV bouts began earlier and contained more complex syllables when mounting attempts ended in copulation. As courtship progressed, the timing of USV and BBV emissions became tightly synchronized, as with duetting of songbirds. We observed several differences in the vocal repertoire and spectral features of calls between mice that successfully copulated with ejaculation and those that did not. USV emission was positively correlated with male sexual behaviours, especially among copulating mice, suggesting that the effect of USV emission on male mating success depends on their sexual behaviour, and vice versa. Our results show that the courtship vocalizations of wild house mice are more complex and dynamic than those previously reported and provide the first evidence for vocalizations that correlate with and predict male copulatory success.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"220 ","pages":"Article 123024"},"PeriodicalIF":2.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143178393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the field, premoulting, gregarious, last-instar nymphs stopped marching and remained on a roosting bush. In response to an approaching simulated vertebrate predator, both pre- and postmoulting nymphs quickly dropped into the bush and hid themselves under branches. Although middle-moulting nymphs that were shedding an old exocuticle were immobile for approximately 10 min, once the femurs were out of the old exocuticle, the insects started to exhibit dropping/hiding escape behaviour. Behavioural experiments confirmed that pre-, middle- and postmoulting individuals were able to extend their wings by climbing after dropping. However, if dropped locusts were not allowed to climb and stayed on the ground, they failed to extend their wings. Hence, our results suggest that the integration of a physically protected moulting site choice before entering the moulting state, a dropping/hiding escape behaviour, which does not require dynamic locomotion, and flexible movement during the soft-bodied state could act to reduce moulting-associated predation.
