Female brood parasites may choose nests by imprinting on the habitat in which they were born, parasitizing nests randomly within their natal habitat, parasitizing a specific nest type or imprinting and preferring a specific host species. We took advantage of our system of nestboxes to conduct the first study on how female brown-headed cowbirds, <em>Molothrus ater</em>, decide which nests to parasitize by testing the nest site and host preference hypotheses. First, we tested cowbird host selection using a paired nestbox experiment with the prothonotary warbler, <em>Protonotaria citrea</em>. One nestbox had an entrance large enough for warblers and cowbirds to enter, while the second box had an entrance that only allowed warblers to enter. Cowbirds only parasitized nestboxes containing warblers and when warblers used nestboxes with small entrances, the cowbirds attempted to lay in those boxes instead of laying in the paired boxes with larger entrances that contained dummy eggs, indicating a preference for the host rather than the nest site. Second, we monitored cowbird host choice within the cavity-nesting community to ascertain whether cowbirds choose hosts based on nest type and use nestboxes at an equal rate (the nest site hypothesis) or whether they select specific hosts within the nestboxes (the host preference hypothesis). Cowbirds never parasitized inactive nestboxes and parasitized prothonotary warblers significantly more frequently than northern house wrens, <em>Troglodytes aedon</em>, and tree swallows, <em>Tachycineta bicolor</em>. Our results support the host preference hypothesis that brown-headed cowbirds choose nests to parasitize based on the individual attributes of hosts, although they may use additional cues such as the nest structure within the cavities and appearance of host eggs.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"223 ","pages":"Article 123157"},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894837","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 research on the impact of USVs is predominantly focused on common laboratory species; however, their exact role in rodents' lives remains unknown. Within vole species, USVs are present during sexual encounters and are primarily emitted by males. Female voles, characterized as induced ovulators, require male stimuli for behavioural oestrus and ovulation. Ultrasounds occurring during male–female interactions may thus serve as external stimuli influencing female reproductive behaviour. In this study, using prerecorded male vocalization, we investigated the effects of male USVs on female proceptive and receptive behaviours towards males in two lab-bred wild-derived vole species: bank voles, <em>Clethrionomys glareolus</em> or <em>Myodes glareolus</em> and common voles, <em>Microtus arvalis</em>. The confrontation between males and females was performed after a significant delay following exposure to the vocalization, rather than immediately afterwards. This approach allowed us to investigate the delayed reactions of females. Our findings reveal that exposure to male USVs before behavioural tests significantly influenced the reproductive behaviour of females in both species. Specifically, we observed an increased frequency of lordosis positions and copulations after the ultrasound exposure, however with variations in the response timing between species. Furthermore, ultrasound exposure notably reduced the latency to the first copulation, suggesting changes in female physiology induced by the USVs. Taken together, this work underscores the significance of male USV as a potential stimulus capable of influencing female voles’ behaviour and potentially their physiology, resulting in enhanced receptivity.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"223 ","pages":"Article 123128"},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894961","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}

In this study, we investigated the efficacy of using a recently proposed, less effort-intensive method for collecting social association data based on the observed order of individuals in single-file movements. We used this method to estimate the social network of a group of semi-free-ranging Barbary macaques, <em>Macaca sylvanus</em> and then applied the Louvain community detection algorithm to estimate the community structure within the group. We validated the results by comparing them to networks informed by data from more traditional sampling methods for social network analysis, namely scan sampling and focal observations. Using Mantel tests with Spearman correlations, we found statistically significant but weak positive associations between the community assignments and dyadic association indices derived from the single-file movement data and those from the scan and focal data. Our findings do not provide convincing evidence that association data obtained from only 20 observations of single-file movements can reliably be used to estimate the strength of dyadic relationships or the composition of discrete communities within the larger group. However, the results from the community detection algorithm converged to similar estimates for the modularity value and the number of communities present in the group, irrespective of the data collection method used. We suggest that data from observations of single-file movements may not be useful for estimating fine-grained social network structure but may offer researchers a ‘quick and dirty’ method for determining whether meaningful community structure exists within their study groups as part of a pilot study and an efficient method for wildlife managers and conservationists to monitor population-level disturbances to social structure.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"223 ","pages":"Article 123146"},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894971","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}

Environmental conditions, especially temperature, can affect these key traits. Environmental conditions can vary across, and frequently delimit, species’ geographical ranges. Pairing suboptimal conditions with relative rarity of conspecifics at range margins may set the stage for hybridization. Despite the importance of mating behaviours as a reproductive barrier, a general understanding of the interaction between behavioural choices and the environment is lacking, in part because systematic studies are rare. With this report, we begin to bridge that gap by providing evidence that temperature has a significant but inconsistent influence on mating choices and success and, thus, on reproductive isolation in <em>Drosophila</em>. We studied mating propensity and success at four different temperatures among 14 <em>Drosophila</em> species in no-choice conspecific mating trials and in heterospecific trials among two <em>Drosophila</em> species triads that are known to regularly hybridize in the wild. We found that mating frequency varied significantly across a 10 °C range (from 18 °C to 28 °C), both in 1:1 mating trials and in high-density en masse trials, but that the effect of temperature was highly species specific. We also found that mating frequency was consistently low and that temperature had a moderate effect on some heterospecific crosses. As conspecific mating propensity decreased outside of the optimal thermal range, while heterospecific matings remained constant, the proportion of heterospecific matings at suboptimal temperatures was relatively high. This result indicates that temperature can modulate behavioural choices that impose reproductive barriers and influence the rate of hybridization. More broadly, our results demonstrate that to truly understand how mating choice and reproductive isolation occur in nature, they need to be studied in an environmental context.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"223 ","pages":"Article 123168"},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894844","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 is because there is increased uncertainty in larger social groups with differentiated social interactions, providing an advantage for more diverse and more flexible signals to transfer diverse messages and to manage the behaviour of others. In this study, we offer a comprehensive approach to contrast the multimodal communicative systems of two closely related true lemur species having similar morphology and ecology but different social systems. We collected behavioural and acoustic data on 13 wild adult red-fronted lemurs, <em>Eulemur rufifrons</em>, belonging to three different groups, and 10 wild adult mongoose lemurs, <em>E. mongoz</em>, belonging to four different groups, in the Kirindy and Ankatsabe forests, respectively. We describe a new analytical framework to assess the complexity of signalling systems across modalities. Applying a multimodal approach may help uncover the different selective pressures acting on the communicative system and better understand adaptive functions that might not be obvious from the isolated study of its components. The results support the prediction of a more complex communicative system in <em>E. rufifrons</em>, which has a more complex social system than <em>E. mongoz</em>. <em>E. rufifrons</em> exhibited larger signalling repertoires, greater signalling rates, a greater number of signal combinations and a significantly lower level of predictability in its signalling network compared to <em>E. mongoz</em>. We discuss the differences in the communicative systems of the two species and the potential functions associated with nonhomologous signals. We further explore potential evolutionary pathways at the communicative system level and discuss the proposed framework’s advantages and limitations at a cross-taxonomic scale.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"223 ","pages":"Article 123163"},"PeriodicalIF":2.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143894840","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}

MR flocks were more cohesive than LR flocks in the novelty challenge, but showed similar levels of cohesion during the novel site homing challenge. Predation threat decreased cohesion in both flock types, with a stronger effect in LR flocks.
