Abstract Periodic episodes of food scarcity may highlight the adaptive value certain anatomical traits, particularly those that facilitate acquisition and digestion exigent fallback foods. To better understand selective pressures favored distinctive dental locomotor morphologies gibbons orangutans, we examined foraging ranging behavior sympatric Hylobates albibarbis Pongo pygmaeus wurmbii during an episode low fruit availability at Tuanan, Kalimantan Tengah, Indonesia. We found ranged 0.5 km...
For orangutans, the largest predominantly arboreal primates, discontinuous canopy presents a particular challenge. The shortest gaps between trees lie thin peripheral branches, which offer least stability to large animals. affordances of forest experienced by orangutans different ages however, must vary substantially as adult males are an order magnitude larger in size than infants during early stages locomotor independence. Orangutans have developed diverse range behaviour cross trees,...
Ecosystem service assessments are increasingly used to support natural resource management, but there is a bias in their application towards terrestrial systems and higher income countries. Tropical marine applications particularly scarce, especially SE Asia. Given the growing coastal population expansion blue economy sectors Asia, evidence effective planning, such as ecosystem assessments, urgently needed. Data deficiencies for systems, (but not only) lower countries significant obstacle...
ABSTRACT Marine plastics stranded on the coastlines of remote small islands threaten both ecological integrity local ecosystems and communities’ well‐being. However, despite growing quantities in these locations, nature sites renders monitoring intervention efforts difficult to undertake. Within this context, we developed a citizen science approach monitor marine collaboration with villagers living island Indonesia. This study reports co‐development application an that can be used maintained...
<title>Abstract</title> Humans accumulate extensive repertoires of culturally-transmitted information, reaching breadths exceeding any individual’s innovation capacity (culturally-dependent repertoires). It is unclear whether other animals require social learning to acquire adult-like information in the wild, including by key developmental milestones, or if are capable constructing their knowledge primarily through independent exploration. We investigated mediates orangutans' diet-repertoire...
<title>Abstract</title> In human infants, exploratory object manipulations (henceforth called “EOM”) stimulate cognitive development and affect performance in later life. Zoo-housed great apes are frequently used to study the evolution of cognition, however, it is unknown how zoo environment affects their daily expression EOM. We investigated wild zoo-housed Sumatran orangutans differ EOM throughout collected ~ 12’000 events by 51 individuals all ages. showed significantly higher rates than...
The long call is an important vocal communication signal in the widely dispersed, semi‐solitary orangutan. Long calls affect individuals' ranging behavior and mediate social relationships regulate encounters between dispersed individuals a dense rainforest. aim of this study was to test utility Acoustic Location System (ALS) for recording triangulating loud free‐living primates. We developed validated data extraction protocol ALS used record wild orangutan males' at Tuanan field site...
Acoustic individual discrimination has been demonstrated for a wide range of animal taxa. However, there far less scientific effort to demonstrate the effectiveness automatic identification, which could greatly facilitate research, especially when data are collected via an acoustic localization system (ALS). In this study, we examine accuracy caller recognition in long calls (LCs) emitted by Bornean male orangutans (Pongo pygmaeus wurmbii) derived from two data-sets: first consists...

This study assessed the conditions a tropical marine biodiversity hotspot, Tambolongan and Polassi islands, located within transition zone UNESCO's Bonerate Reserve islands' reefs receive multitude pressures from anthropogenic...
Abstract Sexually‐selected infanticide by males is widespread across primates. Maternal protection one of many avoidance strategies employed female Bornean orangutan ( Pongo pygmaeus wurmbii ) mothers with younger offspring are less social than older offspring. Additionally, the distance between a mother and decreases in presence male conspecifics, but not conspecifics. We hypothesized that responsible for change mother‐offspring proximity when present. Using year behavioral data from...
Flanged male orang-utans emit loud vocalizations called long calls. In this study, we examined the correlates of variation in long-calling rates among flanged Sumatran orang-utans, as well ranging responses adult females and males to these Males that gave calls more often were likely approach by others. Results bolster a female attraction function did not significantly avoid or However, when alone than guarding mate, approached calls, especially those dominant male, so regardless their...
Abstract In many group-living species, individuals are required to flexibly modify their communicative behaviour in response current social challenges. To unravel whether sociality and communication systems co-evolve, research efforts have often targeted the links between organisation repertoires. However, it is still unclear which or interactional factors directly predict complexity. address this issue, we studied wild zoo-housed immature orangutans of two species assess impact...
Passive acoustic monitoring is a promising tool for at-risk populations of vocal species, yet extracting relevant information from large datasets can be time-consuming, creating bottleneck at the point analysis. To address this, we adapted an open-source framework deep learning in bioacoustics to automatically detect Bornean white-bearded gibbon ( Hylobates albibarbis ) “great call” vocalisations long-term dataset rainforest location Borneo. We describe steps involved developing this...
Abstract From early infancy, human face-to-face communication is multimodal, comprising a plethora of interlinked communicative and sensory modalities. Although there also growing evidence for this in nonhuman primates, previous research rarely disentangled production from perception signals. Consequently, the functions integrating articulators (i.e. organs involved multicomponent acts) channels modalities multisensory remain poorly understood. Here, we studied close-range social...
