Age‐Trajectory of Mother–Infant Relationships in Wild Assamese Macaques
Maternal care is ubiquitous in mammals, yet its degree and duration vary across taxa. In primates, mothers provide extended care for young and follow similar developmental transitions in the mother–infant relationship, yet at different paces of change. Since ecological pressures shape life‐history traits including female reproductive rate and timing of infant independence, research is needed on mother–infant relationships in wild populations expo…
Assessing the Sociodemographic Factors Associated With Mycobacterium tuberculosis Complex Infection Among Free‐Ranging Long‐Tailed Macaques ( Macaca fascicularis ) in Thailand
The threat of disease transmission at the intersection of human‐wildlife interfaces underscores the urgent need for detailed studies on the transmission of human‐borne pathogens across species, especially among nonhuman primates in urban areas. This research focuses on the social and demographic determinants of Mycobacterium tuberculosis complex (MTBC) infection in free‐ranging long‐tailed macaques ( Macaca fascicularis ) in Thailand. Behavioral …
Assessing Gestation and Fetal Sex in Wild Assamese Macaques Using Urinary Estrogen Analysis
In mammals, estrogens and progestogens are crucial for gestation, fetal development, and maternal preparation for parturition and lactation. Measuring these hormones allows for the diagnosis of pregnancy, estimation of pregnancy failures, and potentially prenatal sex determination. We evaluated urinary estrogen and progestogen metabolites as biomarkers for gestation detection and for their utility for fetal sex determination in wild Assamese maca…
Influence of Covid‐19 on the emergence of stone‐tool use behavior in a population of common long‐tailed macaques ( Macaca fascicularis fascicularis ) in Thailand
Stone tool use is a rare behavior across nonhuman primates. Here we report the first population of common long‐tailed macaques ( Macaca fascicularis fascicularis ) who customarily used stone tools to open rock oysters ( Saccostrea forskali ) on a small island along the Thai Gulf in Koh Ped (KPE), eastern Thailand. We observed this population several times during the past 10 years, but no stone‐tool use behavior was observed until our survey durin…
Macaque progressions
Developmental and environmental modulation of fecal thyroid hormone levels in wild Assamese macaques ( Macaca assamensis )
Thyroid hormones are key modulators of development, as well as mediators of environmental conditions, by regulating developmental processes and metabolism in primates. Hormone measurement in noninvasively collected samples, that is, feces and urine, is a valuable tool for studying the endocrine function of wildlife, and recent studies have demonstrated the feasibility of measuring thyroid hormones in fecal samples of zoo‐housed and wild nonhuman …
Reproductive seasonality in wild northern pig-tailed macaques (Macaca leonina)
Prevalence of Enterobacteriaceae in Wild Long-Tailed Macaques (Macaca fascicularis) in Thailand
An expanding human population has increased the risk of zoonosis (Devaux et al. 2019), particularly between humans and wild primates, given our close evolutionary histories and shared ecologies (Fuentes and Hockings 2010). Among the major classes of zoonotic agents, some enteropathogenic bacteria (family Enterobacteriaceae) can cause lethal diarrheal disease and pose a serious threat to all primates (McLennan et al. 2018). Enterobacteriaceae may …
Dominance status and copulatory vocalizations among male stump-tailed macaques in Thailand
The human–primate interface in the New Normal
The emergence of SARS‐CoV‐2 in late 2019 and human responses to the resulting COVID‐19 pandemic in early 2020 have rapidly changed many aspects of human behavior, including our interactions with wildlife. In this commentary, we identify challenges and opportunities at human–primate interfaces in light of COVID‐19, focusing on examples from Asia, and make recommendations for researchers working with wild primates to reduce zoonosis risk and levera…
Extractive foraging of toxic caterpillars in wild northern pig-tailed macaques (Macaca leonina)
Extractive foraging in nonhuman primates may involve different levels of technical complexity in terms of the number of actions that must be performed and the manual dexterity involved. We describe the extractive foraging of caterpillars in wild northern pig-tailed macaques (Macaca leonina) at Khao Yai National Park, Thailand. The study group, observed from May to December 2016 (n = 146 days), comprised 60-70 habituated individuals, including 3-4…
An analysis of white‐handed gibbon male song reveals speech‐like phrases
OBJECTIVES: Our goal was to document song phrases of the white-handed gibbon (Hylobates lar), an Asian ape that produces elaborate songs, often in well-coordinated male/female duets. We focused on the male coda, which is produced during vocal turn-taking with one's mate, and particularly its phrases containing rapid spectral and temporal variation, to investigate if modulation rates resemble those of lip-smacking in other nonhuman primates and hu…
Short dispersal distance of males in a wild white‐handed gibbon ( Hylobates lar ) population
OBJECTIVES: It has long been recognized that in gibbons both sexes disperse from the natal group. However, the fate of dispersed individuals was rarely documented. Here we provide the first detailed information on sex differences in dispersal patterns by analyzing the spatial genetic structure of a well-known white-handed gibbon (Hylobates lar) population. MATERIALS AND METHODS: Mitochondrial DNA (mtDNA) and Y-chromosomal haplotypes, and autosoma…
Mitochondrial DNA and two Y‐chromosome genes of common long‐tailed macaques ( Macaca fascicularis fascicularis ) throughout Thailand and vicinity
Macaca fascicularis fascicularis is distributed over a wide area of Southeast Asia. Thailand is located at the center of their distribution range and is the bridge connecting the two biogeographic regions of Indochina and Sunda. However, only a few genetic studies have explored the macaques in this region. To shed some light on the evolutionary history of M. f. fascicularis, including hybridization with M. mulatta, M. f. fascicularis and M. mulat…
Analysis of sea almond ( Terminalia catappa ) cracking sites used by wild Burmese long‐tailed macaques ( Macaca fascicularis aurea )
Nut-cracking is shared by all non-human primate taxa that are known to habitually use percussive stone tools in the wild: robust capuchins (Sapajus spp.), western chimpanzees (Pan troglodytes verus), and Burmese long-tailed macaques (Macaca fascicularis aurea). Despite opportunistically processing nuts, Burmese long-tailed macaques predominantly use stone tools to process mollusks in coastal environments. Here, we present the first comprehensive …
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 …
Technological Response of Wild Macaques (Macaca fascicularis) to Anthropogenic Change
Anthropogenic disturbances have a detrimental impact on the natural world; the vast expansion of palm oil monocultures is one of the most significant agricultural influences. Primates worldwide consequently have been affected by the loss of their natural ecosystems. Long-tailed macaques (Macaca fascilularis) in Southern Thailand have, however, learned to exploit oil palm nuts using stone tools. Using camera traps, we captured the stone tool behav…
Speech‐like orofacial oscillations in stump‐tailed macaque ( Macaca arctoides ) facial and vocal signals
OBJECTIVES: Speech is unique to humans and characterized by facial actions of ∼5 Hz oscillations of lip, mouth or jaw movements. Lip-smacking, a facial display of primates characterized by oscillatory actions involving the vertical opening and closing of the jaw and lips, exhibits stable 5-Hz oscillation patterns, matching that of speech, suggesting that lip-smacking is a precursor of speech. We tested if facial or vocal actions exhibiting the sa…

An SNP marker at the STAT6 locus can identify the hybrids between rhesus (Macaca mulatta) and long-tailed macaques (M. fascicularis) in Thailand
Morphological characteristics and genetic diversity of Burmese long‐tailed Macaques ( Macaca fascicularis aurea )
Macaca fascicularis aurea (Mfa) is the only macaque which has been recorded to use stone tools to access encased foods. They live in close contact with M. fascicularis fascicularis (Mff) in southwestern Thailand and the hybrids were reported [Fooden, 1995]. Although Mff and Mfa can be seen in the same habitat types, tool-use behavior has never been reported in Mff. Thus, comparing the morphological characteristics and genetics between Mfa and Mff…

Assessment of the hybridization between rhesus ( M acaca mulatta ) and long‐tailed macaques ( M . fascicularis ) based on morphological characters
OBJECTIVES: Hybridization between rhesus (Macaca mulatta) and long-tailed (M. fascicularis) macaques has become a focal point of interest. The majority of such studies have evaluated their genetics, but not their morphological characters. MATERIALS AND METHODS: We analyzed morphological characters of eight free-ranging populations of Indochinese rhesus and long-tailed macaques distributed at the proposed hybrid zone (15.75-21.58° N) in comparison…
Marine prey processed with stone tools by burmese long‐tailed macaques ( Macaca fascicularis aurea ) in intertidal habitats
Long‐tailed macaques ( Macaca fascicularis ) feed opportunistically in many habitats. The Burmese subspecies ( M. f. aurea ) inhabits coastal areas in southwestern Thailand and Myanmar, and some of their populations have adapted lithic customs for processing encased foods in intertidal habitats. We investigated the diet of such macaques in Laemson National Park, Thailand, and identified the variety of foods they processed with stones. We conducte…

Body Size and Proportions and Pelage Color of Free-Ranging Macaca mulatta from a Zone of Hybridization in Northeastern Thailand
Social Relationships in Free-Ranging Male Macaca arctoides
Macaque social relationships differ greatly between species. Based on captive studies that focus mainly on females, researchers have classified stumptail macaque (Macaca arctoides) social relationships as tolerant, as indicated by a high rate of affiliation, frequent aggression, and symmetrical conflicts. To accumulate more data on male social relationships, which are relatively understudied, and to generate comparative data, we investigated male…

Long‐tailed macaques use human hair as dental floss
Long‐tailed macaques in Lopburi, Thailand, use human hair as if it were dental floss. This eccentric behavior is seen mainly in a large group of macaques that live at the old Buddhist shrine of Prang Sam Yot. Many monkeys of this group take hair and sort a few pieces to make a string and then brush their teeth by pulling it tightly with right and left hands alternatively between their teeth. This habit is not seen in the other localities near Lop…
Female long‐tailed macaques with scrotum‐like structure
Female long‐tailed macaques ( Macaca fascicularis ) living in multimale and multifemale societies show a swelling and reddening of the sexual skin around the anogenital region when they approach ovulation. These swellings are limited to the base of the tail in many local populations. We recently observed another type of sexual swelling in long‐tailed macaques inhabiting localities north of the Isthmus of Kra, Thailand. This swelling was located i…
Stone‐tool usage by Thai long‐tailed macaques ( Macaca fascicularis )
In January and March of 2005, we conducted surveys of long‐tailed macaques at Piak Nam Yai Island, Laem Son National Park (9° N 34–35′, 98° E 28′), Ranong Province, situated in southern Thailand. Two of the three troops of long‐tailed macaques found on the island were observed using axe‐shaped stones to crack rock oysters, detached gastropods ( Thais tissoti , Petit, 1852), bivalves ( Gafrarium divaricatum , Gmelin, 1791), and swimming crabs ( Th…

The physical characteristics and usage patterns of stone axe and pounding hammers used by long‐tailed macaques in the Andaman Sea region of Thailand
Stone hammering in natural conditions has been extensively investigated in chimpanzees and bearded capuchins. In contrast, knowledge of stone tool use in wild Old World monkeys has been limited to anecdotal reports, despite having known for over 120 years that Macaca fascicularis aurea use stone tools to process shelled foods from intertidal zones on islands in the Andaman Sea. Our report is the first scientific investigation to look at the stone…

Sex differences in the stone tool‐use behavior of a wild population of burmese long‐tailed macaques ( Macaca fascicularis aurea )
We investigated sex differences in how Burmese long‐tailed macaques ( Macaca fascicularis aurea ) used stone tools to open shelled food items along the shores of two islands in Laemson National Park, Thailand. Over a 2‐week period in December 2009, we collected scan and focal samples on macaques when they were visible along the shores and mangroves. We found females used stones more often while feeding and used smaller tools than males. Females a…

Molecular evidence for the introgression between Hylobates lar and H. pileatus in the wild
Extra‐pair paternity confirmed in wild white‐handed gibbons
Knowledge of the genetic mating system of animal species is essential for our understanding of the evolution of social systems and individual reproductive strategies. In recent years, genetic methods have uncovered an unexpected diversity of paternal genetic contributions across diverse animal social mating systems, but particularly in pair-living species. In most pair-living birds, for example, genetic and behavioral observations have confirmed …

Lar gibbon ( Hylobates lar ) great call reveals individual caller identity
Gibbons (family Hylobatidae) produce loud, elaborate vocalizations (songs), often in well-coordinated male/female duets. The female's great call, the most conspicuous phrase of the gibbon vocal repertoire, functions primarily to mediate territorial defense. Despite the fact that lar gibbons (Hylobates lar) are the most widely distributed and well researched hylobatid species and produce a rich vocal repertoire, the individual-specificity of their…
