Relations between neighboring communities are intensely hostile, and males in the same community cooperate in potentially lethal intercommunity aggression. Permanent community fissions sometimes occur, but genetic data indicate that these are rare, and only a single case, from Gombe, had been known until recently. The unusually large Ngogo chimpanzee community in Kibale National Park, Uganda, observed continuously since 1995, underwent a gradual permanent fission during the 2010s that culminated in the inception of lethal intercommunity aggression in 2018. Males at Ngogo could be assigned to different socio-spatial neighborhoods based on association data before the permanent fission, but data on characteristics of grooming networks show that all belonged to a single community until around 2011. Subsequently, grooming networks showed clear differentiation between what became the Ngogo Central and Ngogo West communities. This preceded the first obvious behavioral signs of permanent fission. In principle, a model developed by Sueur et al. (2011; cf. Sueur and Maire 2014) to explain how increases in group size in papionin primates could lead to fracturing of female grooming networks and facilitate permanent fissions should apply to male chimpanzees, given the importance of male-male grooming for maintaining social bonds and cooperation in intergroup aggression. However, analysis of long-term data on male-male grooming indicates that increases in the number of females at Ngogo and variation in their residence decisions apparently had a greater effect on the dissolution of a community-wide male grooming network than did increases in the number of males. These results support the hypothesis that the main drover of the permanent fission was male reproductive competition, not constraints on the ability of males to maintain grooming networks.</p></div>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"87 10","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145146925","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}

We collected 72 milk samples from wild toque macaques (<i>Macaca sinica</i>) in Polonnaruwa, Sri Lanka, up to an infant age (iAge) of 2.2 y and assayed them by standard methods as developed at the Smithsonian's National Zoo. During the first 7 mo <i>M. sinica</i> milk contained on average 86.1% water, 13.9% dry matter, 4.25% fat, 1.62% protein, 7.84% sugar, 0.792 kcal/g energy, 0.083% calcium, 0.026% phosphorus, 0.012% magnesium, 3.32 ppm zinc, 18.1 mM/kg H<sub>2</sub>O sodium, 4.01 mM/kg H<sub>2</sub>O potassium and 16.2 mM/kg H<sub>2</sub>O chloride.

In this paper, we present a demographic history of the Puthuthottam population through comparisons with studies conducted by various research groups, beginning in the 1970s, and report a five-fold increase in population size over a period of four decades. Using Generalized Linear Mixed Models, we analyze and discuss the effects of population demographic parameters on birth rates, including a moderately reduced growth- and birth rate, as compared to previous records for the population. The most frequent contributor to mortality, especially of the vulnerable juvenile age class, was found to be roadkill deaths, followed by other anthropogenic causes, including electrocution on exposed electric lines. We also report a shift in the social system, pervasive across this population, from unimale–multifemale to multimale–multifemale social groups. We strongly believe that the observed drastic alterations to the socioecological profile of the study population, as a result of habitat fragmentation and increased utilization of human habitats, have major implications for the long-term survivability of this macaque population.

Using seeds from fruits, we induced chemical scarification of their outer coat, and with these, intact seeds and seeds found in droppings, we conducted micromorphological analyses, water permeability tests and germination assays. We observed that the passage of seeds through the digestive tract of mantled howler monkeys did not scarify their outer coat, nor did it enhance their water absorption capacity. There was both a positive and negative effect on the germination of <i>Ficus americana</i> and <i>Ficus insipida</i> seeds, respectively. Chemical scarification of the seeds, although it reduced their coat thickness, did not increase water permeability, significantly decreased their viability, and prevented germination. These results suggest that, in the case of small seeds, scarification is not a relevant treatment for germination and may, in fact, be unfavorable. Therefore, the importance of seed consumption by mantled howler monkeys, and other frugivores, may lie in the removal of pulp in terms of the facilitation of germination. Thus, by moving, releasing and cleaning the seeds, these animals may increase the probability that they will encounter adequate environmental conditions for germination and establishment.</p></div>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"87 9","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145038931","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}

Using long-term demographic data on natural populations of 18 primate species, we find a strong positive brain size effect on immature survival, which is already apparent during the first year.

We build on these studies by investigating developmental changes in one of the most common calls of white-faced capuchins (<i>Cebus imitator</i>), the twitter. Specifically, we examined the behavioral context around twitter vocalizations in a wild population of white-faced capuchins in the Taboga Forest Reserve, Costa Rica. We analyzed the use of twitters in relation to behavioral state (social, foraging, travel, or resting), immediate context (approaching and leaving others), and specific social behaviors (grooming and aggression). Immatures (infants and juveniles) twitter primarily in a social state, while adults twitter primarily in a foraging state. The twitters produced by immatures were more closely associated with approaching other group members within 1 m, compared to adults. This contextual shift with development from social to foraging prompted us to also look for corresponding acoustic changes. However, the acoustic properties of twitters were not related to context or age, with the one exception that adult twitters were longer than those from immatures. Overall, our results suggest that the twitter is a call with multiple functions, with a shift in usage from social to foraging contexts across development.
