Understanding the ranging ecology of endangered species is essential in avoiding these traps. The Hainan gibbon (<i>Nomascus hainanus</i>), the world's rarest primate, reportedly takes refuge in suboptimal montane habitats and occupies an abnormally large home range, resulting in suggestions for enhancing montane habitat quality with high priority. However, these conservation suggestions and actions are not based on solid science. For the first time, we habituated two groups of Hainan gibbon, and studied their ranging ecology over a year from January to December 2022. We found that the average home range size of these groups was 164.5 ± 70.6 ha (95% KDE-href) and 155.2 ± 71.1 ha (95% MCP), which is comparable to other <i>Nomascus</i> gibbons and represents an adaptive trait in response to their heterogeneous habitat. Furthermore, gibbons have shown a preference for higher-altitude habitats between 800 and 1100 m, where food is more abundant than in low-altitude habitats. Our findings, combined with the evidence of favorable food conditions and short interbirth intervals of the Hainan gibbon, indicate that montane habitats meet gibbons' life-history requirements and are suitable for them. The idea that “montane habitat is suboptimal” is a cognitive trap. Given the Hainan gibbons' isolated habitat is approaching saturation, we suggest prioritizing ecological corridor construction to enable gibbons to rapidly gain access to other suitable montane forests.</p></div>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"87 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741637","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}

Assisted habitat regeneration is underway in both China and Vietnam to conserve the species. However, the lack of crucial information on habitat use and habitat preferences of these gibbons could severely compromise the conservation outcomes. To understand gibbon habitat use patterns and guide ongoing habitat restoration, we studied the ranging behavior of two cao vit gibbon groups in Bangliang Gibbon Nature Reserve, Guangxi, China. We established vegetation plots within gibbon's habitat along the altitudinal gradient. Then quantified food distribution in different altitudinal ranges. Both groups avoided using areas above 800 m, but preferred lower areas, and they spent more time feeding in low-altitude areas compared to high-altitude areas. Our analysis revealed that the altitudinal ranging pattern was affected by both food distribution and temperature. The gibbons preferred altitudes that provided more food for their diet, and their selectivity for lower altitudes increased as temperatures dropped while they adopted an energy-conserving strategy during cold seasons. Our results suggested that gibbons prefer habitats at lower altitudes, which serve as important feeding sites and provide refuges during cold exposure. Therefore, we strongly propose prioritizing reforestation in areas below 750 m by planting important food species.</p></div>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"87 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741638","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}

This study examined the interplay of familiarity and numeric odds in shaping the behavioral and hormonal responses of male mantled howler monkeys (<i>Alouatta palliata</i>) to simulated intruder calls. Using playback experiments, we tested whether responses were consistent with “dear enemy” dynamics, which predict stronger responses to unfamiliar intruders, or “nasty neighbor” dynamics, which predict stronger responses to familiar intruders. Additionally, we assessed the influence of numeric odds, hypothesizing stronger responses under favorable conditions. Behavioral responses, including vocalization and approach latencies, were primarily influenced by numeric odds, with shorter latencies observed under favorable odds. Vocal duration, however, was longer when intruders were familiar, consistent with “nasty neighbor” dynamics. Hormonal responses, measured via fecal glucocorticoid and testosterone metabolites, increased in response to unfamiliar intruders, supporting “dear enemy” predictions. Interaction effects showed that familiarity modulated approach duration and latency when numeric odds were unfavorable. These findings reveal the distinct roles of numeric odds and familiarity in shaping immediate and prolonged responses to intruders. Numeric odds influenced engagement decisions, while familiarity was related to stress-related hormonal changes and vocal communication strategies. This study contributes to the understanding of intergroup dynamics by clarifying the role of competitive asymmetries and social relationships in conflict management. Future work incorporating multimodal cues and ecological variability will further elucidate the adaptive significance of these responses.</p></div>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"87 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143741432","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}

Here we explore how human food supplementation impacts wild primates by comparing the gut microbiomes of free-ranging brown howler monkeys (<i>Alouatta guariba</i>) in periurban Brazil that do or do not have access to human foods. We found that howler monkeys consuming human foods had reduced gut microbial diversity and reduced relative abundances of fiber degrading microbial taxa, which has been associated with negative health consequences in other animals, including humans. However, the effect size of these differences was relatively small and varied over time. Additionally, the composition of the gut microbiome varied significantly across months, regardless of the access to human foods.

Variation in prehensile tail use between species might result in anatomical variations, as has been shown in primates but remains undocumented in most species. The present study, therefore, sought to describe prehensile tail use and substrate type utilization between two primates, the Guianan red howler (<i>Alouatta macconnelli</i>) and Brown capuchin (<i>Sapajus apella</i>) and one carnivoran, the Kinkajou (<i>Potos flavus</i>).

From October 2022 to September 2023, we recorded the behavior of a group of wild macaques and collected data on food availability, temperature, rainfall, and day length. We found that over a 12-month period, the Tibetan macaques fed on 109 plant species. The main food types consumed were fruits (54.5%), leaves (24.3%), seeds (7.7%), stems (6.5%), flowers (4.0%), and buds (2.5%). Tibetan macaques were found to target fruits as a main resource during months in which fruits were most abundant. During months when fruits were scarce, they increased their consumption of leaves, seeds, and stems. The top three plant species each month accounted for 70.7% of total feeding time indicating that their foraging effort focused on a small number of highly productive plant species each month. The Tibetan macaque daily activity budget was dominated by feeding (3.98 h or 33.7%) and resting (3.81 h or 32.8%), followed by traveling (2.40 h or 20.9%) and socializing (1.45 h or 12.6%). When time spent feeding on leaves increased, the Tibetan macaques experienced a significant increase in time spent resting and a significant decrease in time spent feeding. In addition, during the months of December and January, pine seeds were found to be an important food for Tibetan macaques. It is possible that increasing lipid consumption during the cold winter months serves to offset the additional costs of thermoregulation.
