Adult transfer of solid food to infants has been reported in 45 primate species. For aye-ayes, this behaviour was recorded in captivity where individuals were provisioned, but little is known about this behaviour in the wild. Wild aye-ayes consume hard-to-process foods that are inaccessible to infants such as wood-boring larvae embedded in trees and the endosperm of Canarium spp. seeds which are protected by a hard coat. Learning to process these food resources may be essential for aye-aye development. We used ad libitum sampling to record the social activities and behaviours of a mother and her male infant from January to December 2020 in Sangasanga Forest, Kianjavato, Madagascar. We collected in total 4 hours 57 minutes and 57 seconds of social behaviours. Over two days in December, we observed eight occurrences of the 11-month-old infant usurping Canarium sp. seeds from his mother. Our findings suggest that, due to physical limitations, the infant aye-aye primarily resorted to food transfer via theft to obtain hard-to-process food. Transfer of larvae, their main resource, was not observed, though it may occur until young aye-aye have the bite force needed to gouge holes in substrates and the coordination to retrieve and extract wood-boring larvae. Future research should explore if food transfer differs across individuals' sex, sites and type of food as well as the effects of anthropogenic disturbances on foraging.</p>","PeriodicalId":520627,"journal":{"name":"Folia primatologica; international journal of primatology","volume":" ","pages":"1-13"},"PeriodicalIF":0.8,"publicationDate":"2026-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148458303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We surveyed Philippine tarsiers from 24 June to 10 July 2025 in a mangrove forest within the Del Carmen Mangrove Reserve on Siargao Island. We were able to record 44 sleeping sites from six Philippine tarsiers that were radio-tracked. The tarsiers frequently slept on screw pines, non-mangrove trees, and thickets, although they also used true mangrove species (Rhizophora sp. and Nypa fruticans) within the flooded portions of the site. Adult males were skittish and consistently slept solitarily, whereas the adult females were often accompanied by their juvenile offspring. From the three adult males we fitted with GPS tags, we estimated minimum home range sizes (±SE) of 3.16 ± 0.59 ha based on minimum convex polygons and 4.22 ± 1.34 ha based on kernel density estimates, with percentages of mangrove overlap ranging from 17.56 to 72.99%. Our observations underscore the value of mangrove habitats as potential refugia for supporting insular primate populations against predators, disturbances, and stochastic events, and as evolutionarily significant ecosystems that, along with their behavioral flexibility, possibly contributed to their dispersal across open oceans.

In the mating season, TS displays performed by peripheral and non-group (i.e., non-central) males were almost always accompanied by loud vocalizations, whereas central males were less vocal. Also, non-central males rarely performed female-directed aggressive behaviours, whereas central males frequently did so. Aggression towards females by non-central males poses a potential cost, i.e. punishment by central males, whereas vocalizing to attract females appears to have few costs, if any, yet it might provide substantial reproductive benefits. By contrast, central males performed fewer TS displays with vocalizations as they were at less risk of getting punished for threatening or attacking females. In the non-mating season, almost all TS displays were performed by central males; non-central males were rarely observed in or around the feeding site in the non-mating season. TS displays in the non-mating season may help central males to reinforce their high-ranking positions.

Whereas more distant relatives can avoid competition by occupying distinct ecological niches, more subtle niche partitioning may explain how congeners coexist in the same place at the same time. Here, we examine the behavioral ecology of sympatric furry-eared (Cheirogaleus crossleyi) and Sibree's (C. sibreei) dwarf lemurs at Tsinjoarivo- a high-altitude rainforest in central-eastern Madagascar. Specifically, we followed 24 collared individuals during the pre- and post-hibernation seasons of 2011-2014 to determine activity budgets, spatial distribution, foraging behavior and macronutrient selection. Overall, we find that furry-eared dwarf lemurs, compared to Sibree's dwarf lemurs, had smaller home ranges and traveled shorter nightly distances, spent more time foraging and less time in their resting sites. The species were somewhat spatially differentiated, with furry-eared dwarf lemurs more often found closer to forest edges and in generally more degraded habitats. Furry-eared dwarf lemurs consumed a more diverse diet, but both species foraged for fruits (and flowers) that were rich in sugars and/or fats, key nutrients particularly during the fattening season prior to hibernation. Since this study was conducted, anecdotal observations at this site strongly suggest that the furry-eared dwarf lemur is replacing Sibree's dwarf lemur, in step with ongoing habitat fragmentation and degradation. Placing our results in broader context highlights the furry-eared dwarf lemur as a more generalist species in terms of habitat occupation, geographic distribution, and ecological flexibility. In contrast, Sibree's dwarf lemur seems to be a specialist highly adapted only to Madagascar's intact and high-elevation rainforests. If this is the case, the sympatric occurrence of these two species at Tsinjoarivo may be recent, tenuous, and unsustainable in the long run. We advocate for greater research of the behavioral ecology of sympatric dwarf lemurs at this and other sites across Madagascar.</p>","PeriodicalId":520627,"journal":{"name":"Folia primatologica; international journal of primatology","volume":" ","pages":"1-16"},"PeriodicalIF":0.8,"publicationDate":"2026-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147438780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within the Sofia Region, Inter-River System (IRS) III is the only home to the Ambarijeby mouse lemur (M. danfossi) and the Anjiamangirana sportive lemur (L. grewcockorum). In 2008, surveys of the nocturnal lemurs in IRS III highlighted Anjajavy as a promising site for these species, both of which were listed, at the time, as Data Deficient by the IUCN. Here, 15 years later, we conducted standard, nocturnal surveys at Anjajavy across the dry season to document encounter rates of mouse and sportive lemurs, with sporadic observations of sympatric dwarf lemurs (Cheirogaleus sp. cf. medius) in two areas of the Private Reserve. Overall, we encountered 17.6 mouse lemurs per kilometer, with significant variation by transect area and study month. We saw more mouse lemurs between August and October and a greater number of individuals per sighting in September, likely due to the onset of the reproductive season. We encountered 2.3 sportive lemurs per kilometer, with little variation by transect area or study month. A lack of dwarf lemur sightings from May through September loosely establishes an approx. 5-month hibernation season at this site. Compared to sportive and dwarf lemurs, we observed mouse lemurs at lower heights in the canopy, particularly when feeding. Our survey data of Ambarijeby mouse lemurs and Anjiamangirana sportive lemurs, now respectively listed as Vulnerable and Critically Endangered, reaffirms Anjajavy as a haven for the nocturnal lemurs of IRS III.

We recorded wild sportive lemur vocalisations over a six-week period in early 2023.

Depending on the call type, calls were produced singly, in sequences and combinations, or in extended bouts. We then used an unsupervised machine learning technique, fuzzy c-means clustering, to objectively classify the repertoire and quantify its graded structure using 25 acoustic measurements extracted from the spectrograms. Fuzzy clustering identified two acoustic clusters, revealing gradation both within call types and between clusters. These patterns were visualised with Uniform Manifold Approximation and Projection ('UMAP') dimensionality reduction. We present representative spectrograms for each call type, and compare our results with the published repertoires of other sportive lemur species.

Categorizing primates by diet can be subjective and reductionist as different researchers may define a given dietary category differently and primate diet tends to be quite complex, varying seasonally, for example. As the earliest members of the order Primates were said to experience a shift from insectivory to frugivory, it is important to develop methods to study that dietary shift. The following work treats diet as a continuous variable as the percentage of foraging time spent feeding on insects (%insects) instead of categorizing primates by broad dietary categories. Extant taxa were chosen for this analysis where both relevant dietary data were available in the literature, as well as previously published dental topographic data; in this case Dirichlet normal energy (DNE), which is a measure of surface curvature or sharpness. This study considered 16 non-folivorous primate taxa that vary in %insects, including tarsiers, lorises, galagos, lemurs, platyrrhines, and a cercopithecoid. Results suggest that as taxa spend more of their foraging time feeding on insects, their molar curvature increases. A phylogenetic generalized least squares regression suggests that %insects is significantly correlated ( P < 0.001) and a moderate predictor ( R 2 = 0.579) of molar curvature. This method of treating diet as a continuous variable served as a more nuanced approach to characterize variation in molar topography compared to previous methods of categorizing taxa by diet. Overall, these results provide further evidence that DNE is a useful method for capturing molar shape relevant to important dietary transitions throughout primate evolution, and that treating an aspect of diet as a continuous variable rather than a categorical variable provides insight into important differences in molar form among primates and mammals more generally.</p>","PeriodicalId":520627,"journal":{"name":"Folia primatologica; international journal of primatology","volume":" ","pages":"1-11"},"PeriodicalIF":0.8,"publicationDate":"2026-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146260653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
