The emergence of SARS-CoV-2 in late 2019 and human responses to the resulting COVID-19 pandemic early 2020 have rapidly changed many aspects behavior, including our interactions with wildlife. In this commentary, we identify challenges opportunities at human-primate interfaces light COVID-19, focusing on examples from Asia, make recommendations for researchers working wild primates reduce zoonosis risk leverage research opportunities. First, briefly review evidence zoonotic origins discuss...
Abstract The global trade in nonhuman primates represents a substantial threat to ecosystem health, human and primate conservation worldwide. Most of the involves for pet-keeping, consumption, or biomedical experimentation. We present an overview international through five case studies; each describes different facet this trade. draw on published scientific literature, media outlets, open access datasets, including CITES Trade Database build these studies. Case study 1 role introduced island...
The western hoolock gibbon (<Hoolock hoolock>, Harlan 1834) is a Critically Endangered primate species in Bangladesh and globally Endangered, yet its distribution across the highly anthropogenic disturbed landscapes of southeast northeast not well understood. We assessed occurrence habitats through community engagement activities from January 2018 to June 2022 conducted population surveys field 2019 March 2024 using total count method estimate abundance most habitats. Our results...
Abstract Altitude influences forest structure and food abundance distribution, which in turn affect primate feeding ranging patterns. Javan gibbons ( Hylobates moloch ) are endemic to forests spanning a broad range of altitudes on Java, Indonesia. Most information about gibbon behavior comes from studies lowland forests, while the vast majority wild remaining inhabit hill lower montane forests. We studied diets, activity patterns, three groups hill/lower (950–1,100 m asl) Gunung...
Accurately estimating population sizes for free-ranging animals through noninvasive methods, such as camera trap images, remains particularly limited by small datasets. To overcome this, we developed a flexible model upper limit populations and exemplified it studying group-living synanthrope, the long-tailed macaque ( Macaca fascicularis ). Habitat preference maps, based on environmental GPS data, were generated with maximum entropy combined data obtained from traps, line transect distance...
Abstract Gibbons of both sexes have been observed emigrating from their natal groups, but the consequences dispersal in gibbons are poorly understood, and it is unclear whether these same for sexes. I sequenced a 350‐bp fragment mitochondrial DNA 18 adults seven siamang ( Symphalangus syndactylus ) groups at Way Canguk Research Station southern Sumatra to assess patterns matrilineal relatedness among within fit with different sex‐specific dispersal. A total 11 haplotypes were identified...
Abstract In mammals with biparental care of offspring, males and females may bear substantial energetic costs reproduction. Adult strategies to reduce stress include changes in activity patterns, reduced basal metabolic rates, storage energy prior a reproductive attempt. I quantified patterns behavior five groups wild siamangs ( Symphalangus syndactylus ) detect periods high investment by adults examine the relationships between infant adult patterns. For females, estimated lactation peaked...
Primates tend to prefer specific plant foods, and primate home ranges may contain only a subset of food species present in an area. Thus, feeding strategies should be sensitive the phenology encountered within range addition responding larger scale phenomena such as seasonal changes rainfall or temperature.

Abstract Flowers are included in the diets of many primates, but not generally regarded as making an important contribution to primate energy budgets. However, observations a number lemur, platyrrhine, and cercopithecine populations suggest that some flower species may function key fallback foods periods low abundance preferred (generally ripe fruits), flowers be cases. I report heavy reliance on during study months for siamang ( Symphalangus syndactylus ) population southern Sumatra....
Abstract Malaysia is inhabited by ≥25 nonhuman primate species from five families, one of the most diverse faunas on earth. Unfortunately, Malaysian primates are threatened with extinction due to habitat loss, degradation, and fragmentation, hunting synergies among these processes. Here, we review research issues related their conservation in Malaysia. Despite charisma cultural importance primates, ecological processes such as seed dispersal, robust development biodiversity-related sciences...
Abstract Forest fires can cause direct mortality to wildlife, and the associated habitat damage reduce carrying capacity population densities. However, little is known about long‐term responses of animals fire in wet tropics. From 2000‐2015, we examined siamang ranging patterns damaged by assess effects on these arboreal frugivores. We mapped home ranges (HR) seven groups inhabiting contiguous HR 3‐5, 10‐12, 17–18 years post‐fire. predicted that if connectivity or quality improved over time...
Rhinopithecus roxellana are generally seasonal breeders, although copulation can occur throughout the year. Previous studies suggest that estradiol modulates female sexual behavior during mating season. However, effects of social context on estrogen levels and have not been fully explored. We studied relationship between behaviors fecal estrogens in a group captive R. period instability. collected behavioral data for six months samples at 2–3‐day intervals four spanning nonmating seasons,...
Abstract Small ape habitat throughout Malaysia is rapidly being lost, degraded, and fragmented, the effects of these changes on abundance this taxon are currently unknown. This study assessed group density Hylobates agilis in virgin forest, previously logged forest (1960s–1990s), recently (2015–2017) Ulu Muda Forest Reserve (UMFR), Kedah, Malaysia. We conducted fixed‐point active acoustic triangulation at nine survey areas to estimate density. used vegetation “speed plots” satellite imagery...
Abstract Citizen science‐based research has been used effectively to estimate animal abundance and breeding patterns, monitor movement, for biodiversity conservation education. Here, we evaluate the feasibility of using social media observations assess distribution small apes in Peninsular Malaysia. We searched reports ape Malaysia on (e.g., blogs, Facebook, Instagram, Twitter, YouTube, iNaturalist, etc.), also online, radio, print messaging, word mouth invite citizen scientists such as...
Audience effects on sexual behavior, including changes in copulation frequency and duration the presence of conspecifics, have been reported multimale–multifemale groups several primate species. We examined interaction male behavior with group composition within-group mating pattern a population siamangs ( Symphalangus syndactylus ) containing unimale–unifemale multimale–unifemale using mixed models. Aggression context was never observed. As predicted, however, rates were lower copulations...
