Despite the importance of social information in movement decision making, little is known about how individuals proceed when social information comes from multiple sources. Here, we specifically tackled this issue by experimentally testing (1) how social information from multiple sources is used to make relocation decisions and (2) whether a contrast in this information enables individuals to orient themselves in space. Using the common lizard as a model species, we conducted repeated experiments in which a focal neonate received information from two other neonates coming from distinct peripheral environments before being given the opportunity to relocate to either peripheral environment. Specifically, we focused on information on resource availability and intraspecific competition by considering informants' body mass (BM) at birth and their subsequent food intake. Our analyses revealed that the amount of resources in the informants' environments affected relocation decisions, depending on the focal individual's phenotype. We found the probability of relocation increased when both the informants' food intake and the focal individual's BM increased or decreased. We also found the relocation increased when both the informants' and focal individual's BM increased or decreased. Our findings suggest that focal individuals adjust their relocation response to social information according to their needs and/or physical abilities. Conversely, we found no significant effect of differences in BM between informants or spatial variability in resource availability on spatial orientation. This study highlights that multiple sources of social information that reflect the quality of the surrounding environment (competition or resource availability) can be used for movement decision making.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534674","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}

We reviewed published instances of apparent nutritional coprophagy across all vertebrate taxa, casting a wide net to capture incidental observations as well as focused studies. We found that coprophagy is a recognized, natural behaviour in five of seven vertebrate classes (all except Agnatha and Chondrichthyes), with reports of nutritional coprophagy in over 150 species. Nutritional coprophagy is common among some families and appears to be more common among herbivores and omnivores compared to faunivores. Across all taxa in which they occur, coprophagic behaviours cluster into seven distinct groups, distinguished by source of faeces, life stage, frequency and dietary ecology, as follows. (A) Routine reingestion to fulfil nutrient requirements (20 families of mammals and amphibians); (B) Juvenile nutritional support (11 families of mammals, reptiles and birds); (C) Nutritional supplementation of adults during parental care (18 families of mammals and birds); (D) Adaptation to aphotic, nutrient-poor habitats (2 families of amphibians and bony fish); (E) Frequent supplemental feeding strategy in biodiverse environments (38 families of mammals, reptiles, birds and bony fish); (F) Rare supplemental nutrition (12 families of mammals, reptiles and birds); (G) Targeted ingestion of seeds and fruits found in faeces (7 families of mammals, reptiles and birds). We propose that these groups represent different manifestations of adaptive nutritional coprophagy. Despite the numerous reports of coprophagy that have been documented, the behaviour is still widely considered abnormal or pathological in many animals. Applying this framework may help field researchers, wildlife managers and animal caretakers recognize nutritional coprophagic behaviours and characterize them as part of a dietary strategy. The framework also suggests possible evolutionary pathways for coprophagy as an adaptive behaviour.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534796","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}

Here, we show that, in cooperatively breeding carrion crows, <em>Corvus corone</em>, core social units persist at higher levels of aggregations (roosts). In our study population, individuals live in cohesive territorial kin groups year-round in an all-purpose territory. At night, crows from different territories may sleep communally in one of the four roosts available in the area. By radiotracking 73 individuals, we found that roosts were used mainly in winter and on cold nights in autumn and spring, suggesting a thermoregulatory function of nocturnal aggregations. Interestingly, we also discovered that members of the same social group preferentially used the same roost, showing a social cohesion that was not achieved by mere attraction to the same roosting site but was based on an active choice of joining groupmates. Therefore, our results indicate that social preference persists in different aggregation contexts in cooperative crows, revealing a further complexity of their society and suggesting a social function of roosts. However, different social groups did not merge in a stable and predictable way at the roost level, providing weak support for a multilevel society in this population.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534673","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}

Despite often being viewed as static, persistent linear structures, hierarchies are fundamentally dynamic and can change over time due to ecological conditions, demographic changes and ontogenetic development. There are numerous methods used to construct hierarchies and quantify individual dominance rank, but methods to capture the dynamics of a hierarchy across time have only recently been developed. As such, relatively little is known about the longitudinal hierarchy dynamics in many social species, including nonhuman primates, and the timescale at which these hierarchy dynamics play out. Here we consider the longitudinal hierarchy dynamics across a 4-year period in a large group of rhesus macaques, <em>Macaca mulatta</em>. We investigated group and individual level predictors of active rank dynamics, or dynamics that arise from rank reversals. We found that, despite rhesus macaques being considered to have relatively stable hierarchies, there was significant active rank mobility in both males and females, even in the face of limited resource competition. Female rank change was not solely driven by matrilineal structure or demographic processes as females also opportunistically ascended in rank. Furthermore, we found strong links between rank certainty and hierarchy dynamics with periods of high hierarchy instability associated with low mean dominance certainty. Lastly, we found limited evidence of associations between periods of high active rank dynamics and social global network structure. This suggests more localized dynamics during hierarchy instability are at play rather than widescale network reorganization. Together, these results stress the importance of considering social context in rank dynamics, illustrate the dynamic nature of macaque dominance rank and further highlight the opportunistic nature of the species.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534671","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 context, we aimed to test whether the Neotropical fruit bats <em>Artibeus lituratus</em> and <em>Carollia perspicillata</em> show individual repeatability (i.e. personality) related to activity, docility and boldness and, if so, whether correlations between these personality axes constitute behavioural syndromes.

For <em>A. lituratus</em>, docility and boldness were positively correlated but activity was not correlated with docility or boldness. Considering these different syndromes, our results suggest that <em>C. perspicillata</em> may show reduced variation in behavioural profiles compared to <em>A. lituratus</em>, likely influenced by species-specific selective pressures.

However, in species lacking parental care, juveniles' behaviour likely has a greater impact on their survival than in species with parental care, owing to the lack of parental feeding and protection. Here, we explored whether affiliative behaviour differed between juvenile and adult eastern water dragons, <em>Intellagama lesueurii</em>, a species with no parental care. Specifically, we investigated the effect of age on individuals’ social associations and social environment (i.e. number of available social partners). We found that adult males were less gregarious, found in smaller groups and had fewer associates than both juveniles and adult females. Additionally, adult males fostered weaker associations than juveniles. Most importantly, this phenomenon was observed despite adult males experiencing similar opportunities to socialize as adult females and juveniles on the observation scale, while having more opportunities than juveniles on the yearly scale.

Here, we provide a broader assessment of intraspecific variation in signals and responses across the range of <em>P. fuscatus</em>. We quantify the amount of perceivable facial pattern variation in each population as a measure of individual identity signalling. We also measure how accurately wasps from each population learn to discriminate between a standard set of conspecific faces as a measure of individual face recognition. We show that wasps are equally adept at learning to discriminate faces of wasps from their own population and faces of wasps from different populations, confirming that discriminating a standard set of faces provides a comparable measure of individual face learning capacity. We find that there is striking variation in signals and responses across wasp populations and that individual identity signals and receiver responses are linked. Wasps from populations with more variable individual identity signals learn to discriminate between a standard set of conspecific faces more accurately than wasps from populations with less variable individual identity signals.

Among species, hiding is associated with the availability of cover habitat; however, our understanding of these behaviours often has been limited to relatively coarse and infrequent observations. We leveraged modern technologies, including GPS collars affixed to neonates, LiDAR, fine-scaled encounter risk with predators, accelerometers and multiscale temperature readings, to complement these observations in evaluating how predation risk, thermoregulation and nutritional attributes of habitat contribute to hiding behaviour and its consequences for survival in mule deer, <em>Odocoileus hemionus</em>. Hiding decisions by mule deer were nuanced and counter to prevailing notions that suggest hiding is associated with increasing availability of cover. In support of the risk hypothesis, mule deer were most likely to hide in areas where vegetation height was low and encounter risk with predators was high, and behavioural shifts were prominent relative to variation in time of day, with hiding behaviour increasing at night during periods of predator activity. Nutrition and thermoregulatory hypotheses were supported in that hiding was more likely and neonate and mother were in closer proximity in areas with greater resource availability, and neonates adjusted hiding behaviour to minimize thermoregulatory costs. Variation in hiding indicated the importance of activity and interaction with the mother for neonate survival. Broad-scale habitat patterns have proven useful for defining hiding behaviour across species and may play an important role in setting the bounds that define individual variation; however, we encourage considering local conditions as drivers of hiding and following behaviour in ungulates. Together, patterns across multiple scales are more likely to describe the nature of neonate behaviour, relative to considerations at one scale alone.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":null,"pages":null},"PeriodicalIF":2.3,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534797","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}
