However, while extensive investigation into the sensory basis of maps has implicated roles for visual, olfactory and magnetic cues, many details of their mechanism and ontogeny are less well understood. Here, we introduce a framework that deconstructs maps into three components: (1) cues, the nature of the environmental properties that animals use to determine goalward directions; (2) structure, the organization of information used to determine the goalward direction, distinguishing discrete and continuous map structures; and (3) implementation, encompassing strategies relating to how animals approach their goals and how animals combine multiple information sources. In some cases, inherited rules and imprinting are involved in the ontogeny of these components of map and compass navigation. However, in many instances, including those which require extrapolation of gradients or involve flexible navigation between multiple goals, extensive learning is probably required; none the less, how animals resolve the spatial arrangement of cues to learn maps, especially over large scales, is little understood. Mechanisms for determining vectors of self-motion, termed path integration, play an important role in map learning in mammals over relatively small spatial scales; we suggest that path integration could play a similar role in map learning in other taxa and over larger spatial scales. This would imply that path integration is more taxonomically widespread and plays a greater role in navigational learning than currently appreciated. This review helps to clarify links between disparate findings and raises questions about navigational mechanisms and ontogeny to better our understanding of map and compass navigation across taxa and scales.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"227 ","pages":"Article 123272"},"PeriodicalIF":2.3,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144680418","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}

The benefits of helping behaviour, such as raising the young of conspecifics, are well studied in cooperative breeding systems, where kin selection plays a role. However, for communal breeding, which consists of multiple, unrelated individuals with shared reproduction, such benefits and the impact of parental care remain poorly understood. Thus, in this study, the combined effects of communal breeding and parental care on reproductive success and offspring traits were investigated using burying beetles, <em>Nicrophorus vespilloides</em>, which is a species that breeds in pairs or communal groups and provides care for larvae during pre and posthatching. The reproductive shares in communal groups were also examined through parentage analysis. Single carcass was allocated to breeding groups of either two pairs (communal breeding) or one pair (pair breeding) of beetles, thereby manipulating the parental treatment by allowing larvae to be raised in the presence or absence of posthatching care (full care versus half-care) for both breeding groups and observing their reproduction and offspring performance. Communal breeding was expected to enhance offspring development compared with pair breeding because of more breeders increasing cooperative care for larger communal broods. Contrary to expectations, communal groups produced smaller offspring but the same brood sizes compared with pair-breeding groups. As predicted, the absence of posthatching care resulted in smaller offspring in both breeding groups, whereas its absence did not impose considerable cost in communal breeding compared with pair breeding. Dominants in communal groups accounted for most reproduction compared with subordinates, but dominants and subordinates produced substantially fewer larvae compared with pair-breeding females. Therefore, communal breeding results in higher costs than more benefits for reproduction and offspring fitness, where more breeders may not necessarily provide enhanced total parental care to the offspring of shared broods.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"227 ","pages":"Article 123269"},"PeriodicalIF":2.3,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144680420","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}

As only the baited cup makes a noise when shaken, the animals can locate the reward by inferring that only a baited cup would make noise that an empty cup would make no noise or both. In a previous iteration of this paradigm in wolves, <em>Canis lupus</em>, and dogs, <em>Canis familiaris</em>, wolves seemed to outperform dogs.

Results indicate that wolves and dogs made their choices based on the saliency and order of the stimuli presented and not based on inference, which is consistent with the previous study.

As such, understanding how animals respond to unequal outcomes is key to uncovering evolutionary roots of cooperation and fairness. Recent research has demonstrated that various animal species respond negatively when they receive less preferred rewards than a partner for completing the same task, often refusing the reward or withdrawing from the task. While most studies on inequity aversion focus on dyadic contexts, which ensure experimental control, these settings do not capture the complexity of natural social environments and may limit partner choice. In this study, we explored responses of brown capuchin monkeys, <em>Sapajus</em> [<em>Cebus</em>] <em>apella</em>, to inequity in a more naturalistic group context, extending their well-documented inequity aversion from dyadic contexts. We compared both food refusals and the number of trades in a token exchange task across various conditions (advantageous and disadvantageous inequity, contrast and equity) involving different combinations of food values. Considering refusals, as in dyadic studies, brown capuchin monkeys were sensitive to disadvantageous inequity, refusing low-value rewards when their partners received higher-value rewards, but rarely rejecting medium- or high-value food. Unexpectedly, we found a negative response to contrast and advantageous inequity, neither of which had been observed in previous studies. In contrast, the number of exchanges capuchins initiated was driven by food value, with no effect of what their partner received. We discuss various factors, such as group dynamics and constraints of the tasks that may explain differential responses in group versus dyadic contexts pointing to new research directions. This study highlights the importance of more naturalistic conditions to achieve a nuanced understanding of the impact of the social context on primate decision making.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"226 ","pages":"Article 123257"},"PeriodicalIF":2.3,"publicationDate":"2025-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144605390","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}

Other prey can innately recognize these cues, allowing them to reliably estimate the level of risk present in a habitat. Unsurprisingly, researchers widely apply alarm cues across aquatic taxa to study antipredator responses of prey organisms. As alarm cues degrade quickly, scientists often freeze them to retain efficacy over extended periods. While many past studies have successfully used frozen cues to induce antipredator defences, uncertainty remains regarding whether these responses match the magnitude of those elicited by fresh cues. Only rarely have empirical comparisons been conducted between these cues, and in the few instances that have occurred, researchers have primarily assessed short-term behavioural responses. While incorrect short-term responses incur low costs and may thus be triggered by inaccurate cues, the high costs of long-term morphological plasticity should select for greater cue scrutiny. Thus, we comparatively assess both behavioural and morphological responses to these cues and do so for the first time in an invertebrate species, the gastropod <em>Physella acuta</em>. We exposed individuals one time (for behavioural trials) or lifelong (for morphological trials) to either fresh conspecific alarm cues, previously frozen conspecific alarm cues, a fresh water control as well as a previously frozen water control. We then assessed their crawl-out behaviour or their shell thickness, both established antipredator responses in this model system. In line with previous research, exposure to alarm cues induces faster crawl-out behaviour and thicker shells compared to the water control. Furthermore, previously frozen and fresh alarm cues induce comparable responses, suggesting that at least in <em>P. acuta</em>, continuing this convenient practice that also reduces donor animal use does not seem to have unintended consequences.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"226 ","pages":"Article 123252"},"PeriodicalIF":2.3,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144564084","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}

This study investigates whether honey bees, <em>Apis mellifera</em>, show directional biases during a foraging task in an artificial meadow and how this affects their trajectories and foraging efficiency. Twenty bees from four colonies foraged from 16 artificial flowers arranged in a 4 × 4 grid. We measured their overall directional biases in visiting (and revisiting) flowers and in the first flower choices over 16 trials. Moreover, we analysed foraging consistency and efficiency. An overall rightward population level was observed across trials. When analysing only the first flower choices, seven bees showed significant lateral biases (three favouring right and four left). Foraging efficiency, measured by time and trajectories, showed no clear pattern; only two lateralized individuals showed faster times and more consistent paths than nonlateralized bees. The results suggest that individual lateralization may not significantly impact foraging efficiency but could be advantageous for colony resource distribution. For all bees, whether lateralized or not, there was a strong correlation between trajectory similarity and foraging time: the more consistent the paths, the quicker the foraging. This study highlights lateralization in honey bees as a dynamic, context-dependent trait, potentially offering varying advantages depending on the task.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"226 ","pages":"Article 123237"},"PeriodicalIF":2.3,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144534393","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}
