Proyecto Tití has been leading conservation efforts in Colombia and has developed successful conservation education programs that engage communities in activities that promote the long-term survival of cotton-top tamarins. TITIRITIANDO is an educational theatrical program that introduces children to cotton-top tamarins and the challenges they face in the illegal pet trade. We presented this program to 4018 elementary school children to determine if using puppets and interactive messaging created an emotional connection between children and cotton-top tamarins that inspired them to engage in actions that aid cotton-top tamarin conservation. Pre- and post-test evaluations were conducted on 1917 students. Pre-surveys found 34% of the children were unable to identify at least one action to help cotton-top tamarins. Following the program students could on average identify at least 3 actions that positively impacted cotton-top tamarins with \"not having a cotton-top tamarin as a pet\" (75%) as the most frequently sited response. Misconceptions regarding the health and wellbeing of pet cotton-top tamarins was evident with 20% of the students believing that animals were well cared for and had a better life living with people than in the forest. Following the program, students were able to understand and empathize with pet cotton-top tamarins and on average could identify at least 3 negative impacts on individual welfare/well-being with the most common answers as they (1) are sad/depressed (91%), (2) die (87%), (3) are fed an inappropriate diet (80%), (4) have lost their family (74%) and (5) have lost their freedom (39%).

We compared the performance of instantaneous group scan sampling (scan sampling) and focal continuous sampling with variable session durations (focal sampling) in estimating activity patterns, diet composition, and spatial proximity in seven groups of wild coppery titi monkeys ( Plecturocebus cupreus ) in Peruvian Amazonia. We used a series of paired samples Wilcoxon tests to compare daily proportions of time allocated to each type of activity/food/proximity category in each sampling method. In addition, we compared our results with those of other studies conducted on the same population of titi monkeys at other times. Focal sampling provided significantly lower estimates for moving time and significantly higher estimates for resting time compared to scan sampling, likely because scan sampling tends to give higher estimates of more conspicuous behaviors and lower estimates of less conspicuous behaviors. For diet composition, scan sampling gave similar results to other studies, while focal sampling gave significantly lower estimates for feeding on fruits and higher estimates for feeding on arthropods. The most likely reason is that focal sampling with variable session durations tends to overestimate behaviors during which a focal animal is less likely to go out of view, such as feeding on arthropods in the lower strata of the forest. Our results suggest that a pilot study comparing different methods should be conducted prior to collecting data, as not all methods are interchangeable.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135618498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Very little is known about the extent of illegal trade and its impacts on declining primate populations. Our study proposes a potential method based on estimating the number of individuals that die in the trade before being detected and those that probably cannot be detected. This facilitates estimating the number of animals extracted and allows an assessment of how trafficking impacts their populations. We derive estimates from seizure data of primates in Mexico between 2010 and 2019. To do this, we created wildlife detection rates and mortality rates from the existing literature (scientific articles, journalistic articles, and notes) to estimate the number of primates that die during capture, transport, and sale and the number of trafficked primates that were not detected by Mexican authorities. We estimate that 946 primates were removed from the wild for the pet trade each year (spider monkey Ateles geoffroyi = 854; black howler monkeys Alouatta pigra = 38, mantled howler monkey Alouatta palliata = 54). The annual reduction in population size caused by trafficking was greatest for Ateles geoffroyi (2.2%), followed by Alouatta pigra (1.3%), and Alouatta palliata (0.4%). Our estimates show the percentage of impacts that trafficking has on Mexican primate populations. Nevertheless, trade has the potential to impact declining populations and still must be addressed.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136038212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Andean night monkey (Aotus lemurinus) is a nocturnal American primate living in mountain forests in the Northern Andes with scant information on its behavior and ecology. The main goal of this study is to describe the vocal repertoire of a group of wild Andean night monkeys and compare it with earlier bioacoustics studies on the only nocturnal platyrrhines. We recorded the vocal behavior of a group of night monkeys living in the eastern Andes of Colombia between August and December 2019. Based on an auditory and a visual inspection of the vocal records, and through a quantitative analysis of the acoustic parameters of the vocalizations, we were able to identify five different calls emitted by the Andean night monkey. Four of these calls are stereotyped while the fifth vocalization (Squeak) is more variable, having different forms. Additionally, one call (Acetate) was found to be unique to this species. The result of this study contributes to the scant information on the ecology and behavior of the Andean night monkey and sets baseline information on the vocal behavior of night monkeys that may be used in future studies on communication of these and other nocturnal primates.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49087348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These patterns can be observed in multiple social contexts and across all ages, and can serve functions such as appeasement, reconciliation, practice and dominance assertion. In this study, we investigated same-sex and immature sexual behaviour in a group of robust capuchins (Sapajus nigritus) living in an Atlantic forest fragment and urban areas. We predicted that in order to practice sex, sexual behaviour in same-sex dyads and/or dyads that included immatures would resemble the adult heterosexual repertoire for solicitation through courtship displays, mounts and post-copulatory display. We also predicted that immature individuals would engage more frequently than adults in sexual interactions, in order to practice sex. We conducted all-occurrence observations of sexual behaviour in the study group (28 individuals: four adult males, one sub-adult male, eight adult females, eight juveniles and seven infants) from September 2016 to August 2017. Sexual interactions that included at least one immature individual in the dyad and/or occurred between individuals of the same sex were infrequent (N = 52, 0.13 interactions/hour), but much more frequent than heterosexual sexual interactions between adults in the group (N = 4, 0.01 interactions/hour). The same-sex and immature sexual repertoire resembled the described heterosexual patterns for the same species from the literature. Individuals displayed solicitation behaviours in “one-way courtship”, usually followed by a two-way courtship and then mounts, but post-copulatory behaviour was never observed. Except for the alpha male, all age-sex classes engaged in sexual interactions in same-sex dyads or in dyads that included immature individuals. We found no difference in frequency of participation across age classes, however, male-male dyads engaged more frequently in sexual interactions and may be practicing sex and courtship behaviours. Mounts are unlikely to be a form of dominance assertion as the alpha male did not participate, subordinate adult males did not engage in mounts with other subordinate adult males, juveniles mounted adult males and vice versa, and there were mount switches (taking turns as mounter and mountee) regardless of the initial mounter’s age. Contrary to the post-conflict context observed in Cebus, most mounts in this study were preceded by play. Combining our study with additional evidence for the genus, same-sex mounts and mounts that include immatures seem to occur most commonly in affiliative contexts within Sapajus. Sexual behaviour functions in Sapajus require additional investigation, especially among adult males and juveniles of both sexes.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43898797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The activity budgets of the macaques were stable across sites regardless of geographic, climatic, and anthropogenic characteristics, but dietary composition varied among habitats; the percentage of fruits and seeds was significantly lower at higher latitudes. The plasticity of frugivory in response to regional variations in the food environment was similar to that of macaques inhabiting temperate regions. In habitats with strong human activity, the percentage of anthropogenic foods in the macaque diet was remarkably higher, and fruits and seeds was lower than that in natural habitats.

Here, we compared drawing behaviour using fingers or tools on a touch-sensitive monitor between five chimpanzees from the Kumamoto Sanctuary (KS) and two from the Primate Research Institute (PRI), both located at Kyoto University, Japan. Regarding drawing duration, both PRI females drew relatively longer than the other, with the exception of one KS female. However, a long drawing duration did not correspond with a decrease in the number of pauses, which can be interpreted as a lack of concentration or interest. Therefore, to better understand the engagement of individuals, we recorded the time spent looking at the touchscreen. Pan, one of the two PRI females, had the longest drawing periods and spent the most time looking at the screen. We compared her with Ai, the other PRI female, to better understand their individual marking techniques and behaviours. By adapting to each one’s specific behaviour and previous experience with tool-assisted drawing on paper, we offered the females appropriate tools for making marks on the touchscreen. Our results indicate that electronic devices are not limiting in the expression of drawing behaviour. The females did not have the same drawing technique and also showed different types of engagement as motivation, which could not have been detected by only studying the completed drawings. By focusing more on the process rather than on the drawings themselves, we try to show inter-individual differences in drawing behaviour of chimpanzees and the relevance to adapt to it as experimenters.","PeriodicalId":50437,"journal":{"name":"Folia Primatologica","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44921077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the initial phase of separation, a period of habituation to group members followed during which the infant was brought to the front of the group enclosure daily for two months. We then started a phased reintroduction process that lasted a year. Because the biological mother was the group member most attracted to the infant, the process began by allowing the two individuals to interact. In the next stages, we introduced the infant to the other individuals one after the other, starting with the females. Females then acted as protectors against potential male aggression. At the age of one year and two months, the introduced individual had fully integrated her original group. Two years later, she appeared to behave like the other group members.
