American Journal of Primatology. 2026;88:e70148. https://doi.org/10.1002/ajp.70148Upon reviewing the final published version, we identified a typographical error in the Figure 4 legend, where the subpanel labels were mismatched.

(f) Correlation heatmap of viral-bacterial functional associations in the wild group.In the published legend, panels d and e were incorrectly labeled as the LEfSe analyses, while panels b and c were incorrectly labeled as the PCoA and Mantel test. This was a caption labeling error only and does not affect the original data, analytical results, or research conclusions.The corrected Figure 4 legend is as follows:FIGURE 4 (a) PCoA of gut viral KEGG functional profiles (Level 3) based on Bray-Curtis distance.

During two separate periods (November 2022 and April 2023), we monitored encounters between tourists and Indri, categorizing tourist group size into small (1–5) and large (> 5) groups, recording who the initiator of encounters was and the behaviors of both actors. Observations were recorded using ad libitum sampling. Tourists mainly initiated interactions during encounters, accounting for 65.4% of observed cases (N = 144/220). Indri initiated 28.2% (N = 62/220) of interactions while guides accounted for the remaining 6.4% (N = 14/220). Tourist-initiated behaviors primarily included approaching Indri (44.5%, N = 64/144), observing them (38.9%, N = 56/144), remaining indifferent (9.02%, N = 13/144), imitating their calls (6.2%, N = 9/144), and shaking a branch and feeding them (1.38%, N = 2/144). Only tourist-initiated acts had a noticeable effect on Indri responses. Indri tended to avoid approaching when tourists approached, but approached when tourists looked away. Tourist's group size seemed strongly associated to Indri. Smaller tourist groups often responded by emitting Indri vocalizations, presumably unaware that they were territorial vocalizations. The territorial calls of Indri are very famous in Analamazaotra, and the guides probably explained their significance to tourists. Larger tourist groups tended to result in Indri either “looking away” or “ignoring” them. No significant difference was observed between the number of daily interactions and Indri responses. If choosing indifference instead of escaping were to limit energy expenses in Indri, conservation efforts should take this into account when educating ecotourists.</div>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148040783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, even fewer have examined the responses elicited by these markings. In this study, we investigated the response behaviors to scent marking in wild tamarins. We hypothesized that scent serves a sexual communication function to facilitate mate attraction and/or mate guarding, and predicted differences in the number and type of responses by males and females. We further predicted increased response rates at the periphery of the home range, where reproductive competition with neighboring groups may be higher. We focused on a group of wild saddleback tamarins (Leontocebus weddelli) and recorded investigatory and overmarking responses to each observed scent marking event, together with the GPS location where the scent was deposited. We found that scent marks of the single breeding female received the highest number of responses, consistent with a role of olfaction in mate attraction. Additionally, most overmarks were performed by primary breeding males in response to female scent marks, suggesting that odor may play a role in mate guarding, potentially mediating male–male competition. However, location within the home range was not associated with the likelihood of responses. Overall, olfactory communication within the social group occurred primarily between the breeding female and the breeding males, with males responding to her scent marks through both investigation and overmarking. Our results provide new data on scent-based communication and putative reproductive dynamics among group members.","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 5","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ajp.70167","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148040723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
