Salivary tannin ‐binding proteins are a pervasive strategy used by the folivorous/frugivorous black howler monkey
Dietary tannins can affect protein digestion and absorption, be toxic, and influence food selection by being astringent and bitter tasting. Animals that usually ingest tannins may regularly secrete tannin‐binding salivary proteins (TBSPs) to counteract the negative effects of tannins or TBSPs production can be induced by a tannin‐rich diet. In the wild, many primates regularly eat a diet that contains tannin‐rich leaves and unripe fruit and it has been speculated that they have the physiological ability to cope with dietary tannins; however, details of their strategy remains unclear. Our research details the salivary...

Gastrointestinal protists and helminths of habituated agile mangabeys (Cercocebus agilis) at Bai Hokou, Central African Republic
Infectious diseases including those caused by parasites can be a major threat to the conservation of endangered species. There is thus a great need for studies describing parasite infections of these species in the wild. Here we present data on parasite diversity in an agile mangabey (Cercocebus agilis) group in Bai Hokou, Dzanga‐Sangha Protected Areas (DSPA), Central African Republic. We coproscopically analyzed 140 mangabey fecal samples by concentration techniques (flotation and sedimentation). Agile mangabeys hosted a broad diversity of protistan parasites/commensals, namely amoebas (Entamoeba spp., Iodamoeba buetsch...

The effects of social context and food abundance on chimpanzee feeding competition
We presented tolerant pairs of chimpanzees from a semi‐captive social group with an apparatus comprising a matrix of transparent tubes between two adjacent rooms, of which, either all (abundant condition) or only a small proportion (scarce condition) were baited with peanuts. Dyads were either grouped into the competitive treatment, in which peanuts were accessible from both sides of the apparatus simultaneously, or the non‐competitive treatment, in which the peanuts were pre‐divided; half of the tubes were accessible to one chimpanzee from one side, and the other half were accessible only from the opposite side of t...

The influence of phylogeny, social style, and sociodemographic factors on macaque social network structure
Among nonhuman primates, the evolutionary underpinnings of variation in social structure remain debated, with both ancestral relationships and adaptation to current conditions hypothesized to play determining roles. Here we assess whether interspecific variation in higher‐order aspects of female macaque (genus: Macaca) dominance and grooming social structure show phylogenetic signals, that is, greater similarity among more closely‐related species. We use a social network approach to describe higher‐order characteristics of social structure, based on both direct interactions and secondary pathways that connect group m...

“Stink flirting” in ring‐tailed lemurs (Lemur catta): Male olfactory displays to females as honest, costly signals
Sexual selection for honest behavioral displays of quality has driven the development of remarkably complex courtship behavior in many animal species. Olfactory displays are often overlooked as an area of inquiry compared to auditory and visual displays. Ring‐tailed lemur (Lemur catta) scent marking of substrates has been studied extensively, although the male olfactory displays of anointing and wafting tails to females has received relatively little attention. We studied the role of male olfactory displays to females, evaluating whether such signals function as honest, costly signals of male dominance status in two grou...

Genetic assessment for the endangered black lion tamarin Leontopithecus chrysopygus (Mikan, 1823), Callitrichidae, Primates
This is the first study analyzing genetic diversity in captive individuals of the endangered black lion tamarin, Leontopithecus chrysopygus, and also comparing genetic diversity parameters between wild populations and captive groups using the same set of molecular markers. We evaluated genetic diversity and differentiation for the Brazilian and European captive groups and a wild population through 15 polymorphic microsatellite markers. The genetic diversity levels were similar among Brazilian captive, European captive and wild animals from the National Forest of Capão Bonito. Expected heterozygosity showed values ranging ...

The grand challenge of great ape health and conservation in the anthropocene
“Ecosystem Health recognizes the inherent interdependence of the health of humans, animals and ecosystems and explores the perspectives, theories and methodologies emerging at the interface between ecological and health sciences.” This broad focus requires new approaches and methods for solving problems of greater complexity at larger scales than ever before. Nowhere is this point more salient than the case of disease emergence and control at the human‐non human primate interface in shrinking tropical forests under great anthropogenic pressure. This special edition brings together transdisciplinary experts who have c...

The evolution of cranial base and face in Cercopithecoidea and Hominoidea: Modularity and morphological integration
The evolutionary relationship between the base and face of the cranium is a major topic of interest in primatology. Such areas of the skull possibly respond to different selective pressures. Yet, they are often said to be tightly integrated. In this paper, we analyzed shape variability in the cranial base and the facial complex in Cercopithecoidea and Hominoidea. We used a landmark‐based approach to single out the effects of size (evolutionary allometry), morphological integration, modularity, and phylogeny (under Brownian motion) on skull shape variability. Our results demonstrate that the cranial base and the facial co...

Through the eyes of children: Drawings as an evaluation tool for children's understanding about endangered Mexican primates
This study seeks to understand children's perceptions and knowledge of endangered Mexican primates. The black howler monkey (Alouatta pigra) is a charismatic species endemic to Southern Mexico, Northern Belize, and Guatemala and is a symbol of the region that fosters a sense of local pride. Therefore, it can be considered a flagship species for the forests of Southern Mexico. We evaluated the perception and knowledge that 297 Mexican elementary school children (8–10 years old) have about black howler monkeys. Specifically, we analyzed and categorized drawings made by these children based on gender, geographic context (ru...

Genetic analysis of samples from wild populations opens new perspectives on hybridization between long ‐tailed (Macaca fascicularis) and rhesus macaques (Macaca mulatta)
In the past decade, many researchers have published papers about hybridization between long‐tailed and rhesus macaques. These previous works have proposed unidirectional gene flow with the Isthmus of Kra as the zoogeographical barrier of hybridization. However, these reports analyzed specimens of unknown origin and/or did not include specimens from Thailand, the center of the proposed area of hybridization. Collected specimens of long‐tailed and rhesus macaques representing all suspected hybridization areas were examined. Blood samples from four populations each of long‐tailed and rhesus macaques inhabiting Thailand,...

Cranial shape variation in adult howler monkeys (Alouatta seniculus)
In this study we quantitatively analyzed the cranial shape variation in Alouatta seniculus, to evaluate possible influences and constraints in face and braincase associated with airorhynchy. We also considered the structural role of the pteric area within the cranial functional matrix. We applied landmark‐based analysis and multivariate statistics to 31 adult crania, computing shape analyses based on 3D coordinates registration as well as the analysis of the Euclidean distance matrix to investigate patterns of intraspecific morphological variability. Our results suggest that allometry is the main source of variation invo...

Social play among juvenile wild Japanese macaques (Macaca fuscata) strengthens their social bonds
Social play and grooming are typical affiliative interactions for many primate species, and are thought to have similar biological functions. However, grooming increases with age, whereas social play decreases. We proposed the hypothesis that both social grooming and social play in juveniles strengthen their social bonds in daily activities. We carried out field research on the social relationships among juvenile wild Japanese macaques in a troop in Kinkazan, Miyagi Prefecture, Japan, from fall 2007 to spring 2008 to investigate this hypothesis. We evaluated three relationships among juveniles, play indices (PI), grooming ...
