<title>Abstract</title> This study explores contagious yawning in adult chimpanzees (<italic>Pan troglodytes</italic>) the presence of a non-biological humanoid agent, an android. Chimpanzees observed android portraying specific facial expressions, including yawns and gapes. The results showed that exhibited across-agent yawn contagion, with graded response: highest contagion occurred when displayed fully wide-open mouth (Yawn condition), reduced response was partially opened (Gape no...
The long-term effects of early life adversities on social capacities have been documented in humans and wild-caught former laboratory chimpanzees (Pan troglodytes). However, pet entertainment received little attention to date. This study aimed investigate the experience 18 chimpanzees, based grooming data collected at a primate rescue centre over 12-year period. Moreover, we also focused possible short-term that alterations group composition might patterns. For this purpose, compared stable...
Chimpanzees used as pets and in the entertainment industry endure detrimental living conditions from early infancy onwards. The preferred option for ending their existence pet or circus chimpanzees is rescue transfer to a primate sanctuary that will provide them with optimal social conditions, so they can thrive. In this case study, we had rare opportunity compare activity budgets of three time 2004 at MONA 2020, after almost decade centre. We found behaviour patterns changed accordance...
Housing different animal groups in close-by facilities is common wildlife centers. However, the impact on welfare insufficiently studied literature. In this study, we analyzed behavior of two adjacently housed chimpanzee to investigate how intergroup interactions may affect their and, thus, welfare. We recorded occurrences abnormal and self-directed behaviors, well-known indicators stress chimpanzees. Furthermore, explored social responses said by recording all inter- intragroup affiliative...
Chimpanzee’s nocturnal sleep is a dynamic and complex process, still not fully understood. As in humans, getting enough quality due to frequent or lasting disruptions may affect their physical mental health, hence wellbeing, which be reflected daytime behavior. This study aims understand the impact of abiotic factors, such as temperature humidity on activity well awakening events behavior sanctuary-housed chimpanzees. We monitored noisy through audio recordings for one year, documenting...
Wild chimpanzees (Pan troglodytes) live in flexible fission-fusion societies with frequent changes both group size and composition. These depend mostly on resource availability individual social preferences yet captivity are determined by housing organizations. During a period of seven years, we observed sanctuary chimpanzees, focusing how they adapted to the composition over time. Using linear mixed models (LMMs), factors such as size, sex ratio, seasonality, individuals' origin (wild...
The question of 'if and how captive primates are affected by visitors' has gained increasing attention over the last decades. Although majority reported undesirable effects on behavior wellbeing, many studies contradicting results. Most these were conducted at zoos, typically with little or no control actions. Yet is known about impact under very controlled visitor conditions. In order to fill this gap, we study a primate sanctuary which allows public access only via guided visit strict...
The genus Pan is the closest related to humans (Homo sapiens) and it includes two species: troglodytes (chimpanzees) paniscus (bonobos). Different characteristics, some of biomedical aspect, separate them from us. For instance, common human medical conditions are rare in chimpanzees (menopause, Alzheimer disease) although unclear which extent longevity plays an active role these differences. However, both present similar pathologies, thus, understanding traits can help unravel molecular...
Wild chimpanzees live in large and complex social communities, but their complexity is determined by the number of potential partners as well frequent changes group composition due to fission–fusion dynamics. Alternatively, captive housed chimpanzee groups are usually much smaller less complex. However, studies have shown that can be adjacent habitats, potentially increasing partners, i.e., granting additional relationship opportunities enhanced complexity. While most network analyze closed...
Advances in the field of social network analysis facilitate creation multiplex networks where several interaction types can be analysed simultaneously. In order to test potential benefits this approach, we investigated sociability atypically raised chimpanzees by constructing and analysing 4-layered two groups former pet entertainment (Pan troglodytes). These are based on four (stationary vicinity, affiliative behaviour, allogrooming, passive close proximity) representing low- high-level...
Human fascination with chimpanzees has driven extensive research on the species, but also led to exploitation by private owners and entertainment industries. These animals often suffer species-specific inadequate conditions, which can result in development display of abnormal behaviors even after rescue. highlight importance for zoos sanctuaries actively prevent worsening effects previous treatment providing apes social stimulating environments that support their recovery. We conducted a...
ABSTRACT Captive housed non-human primates, specifically great apes such as chimpanzees (Pan troglodytes) are frequently reported to have died from or diagnosed with potentially fatal heart conditions that require the monitoring of physiological signals electrocardiogram (ECG) respiratory rate. ECG screening must be conducted after applying full anaesthesia, causing potential physical and emotional stress well risk for animal. Here, we present an electronic system simultaneously measures...
