“…the extent to which individuals are integrated into their social environments: Brent et al 2008) seem to affect individual stress levels (Engh et al 2006;Brent et al 2008;Crockford et al 2008;Wittig et al 2008;Emery Thompson et al 2010). As the link between stress and behavioural measures of anxiety is not yet fully understood (Higham et al 2009;Wascher et al 2010;Campbell & Ehlert 2012), future studies should adopt a multidisciplinary approach combining physiological, behavioural and possibly social network data, so as to comprehensively examine the underlying mechanisms that regulate emotional responses to social events.…”

“…SDBs thus provide simple behavioural indicators that can be used in a variety of species in a comparative perspective (e.g., humans: Troisi ; primates: Aureli & Fraser ; birds: Wascher et al. ; Radford ; rodents: Ferkin ). By examining SDB variations, researchers can non‐invasively investigate the factors that affect individual emotional responses in a variety of contexts with the appropriate temporal resolution.…”

Emotional responses to social interactions and the associated behavioural measures (e.g., self‐directed behaviours, SDBs) have been little studied in New World monkeys, especially in wild settings. In this study, we investigated the factors affecting anxiety in a wild group of tufted capuchin monkeys (Cebus apella nigritus) using self‐scratching (hereafter scratching) as its measure. Scratching was more strongly affected by the social context than by individual characteristics. Indeed, inter‐individual variability was not explained by the age, sex and dominance rank of the monkeys. The monkeys scratched themselves more often when being distant from other group members than when in close proximity with them, suggesting that even short‐distance separation from group members may be an important factor affecting capuchins emotional response. The risk of receiving aggression seemed also to elicit anxiety, as scratching was higher when in proximity to more dominant individuals and females, which were the categories of group members that were more aggressive. By contrast, scratching was lower when in proximity to more secure partners, like kin. Finally, scratching rates following the receipt of aggression were higher than at baseline, indicating a post‐conflict increase in anxiety. Overall, our results contribute to the understanding of the factors affecting emotional responses in capuchin monkeys, confirming and expanding previous findings in other animal species.

“…A particular emphasis of this review was placed upon variations in HR occurring under natural conditions and during interactions with humans, human developments, and agricultural regions. This provided insight into changes in metabolic rate in response to human and environmental stressors [8,[25][26][27][28][29][30].…”

Development and utilization of implantable cardiac monitors in free-ranging American black and Eurasian brown bears: system evolution and lessons learned

et al. 2018

Biologgers can be used to monitor both human and animal physiology and behaviors, activity patterns, and/or environmental stressors. Monitoring of heart rates and rhythms, respiratory patterns, and activity in free-ranging bears can provide unique insights into physiological mechanisms. Such research can also influence the conservation of wildlife, the management of human-wildlife conflicts, and potentially human medicine. Here we describe our experiences with the development and utilization of three generations of implantable biologgers in American black and Eurasian brown bears (Ursus americanus and Ursus arctos arctos). These devices have enabled novel investigations into the underlying mechanisms for winter survival, including the discovery of an extreme respiratory sinus arrhythmias that acts to conserve energy while providing adequate circulation to maintain alertness (i.e., "fight or flight" behaviors). Extreme variations in heart rate have also been documented, including a 33.8 s asystole and a 261 beats/min sinus tachycardia in black bears and a 39.4 s asystole and a 240 beats/min sinus tachycardia in brown bears. Long-term data recording has also identified annual trends in heart rates and activity in both species. Combining physiological data with concurrent GPS collar locations provided insights into the impacts of human and environmental stressors (hunting, predation by other bears, road crossings, drones), which would not have been apparent through spatial data analysis alone. More recently, short-range wireless telemetry has allowed for real-time streaming of data via telemetry stations placed in remote den locations. Future iterations include transponders for biomonitoring and as an early warning system to aid in the prevention of poaching in free-ranging animals. In this review, we discuss the primary experimental capabilities of the current and next-generation systems. We highlight device evolution in terms of new physiological measurements (e.g., temperature, activity, impedance, posture), increased data storage capacity, improved wireless capabilities, and miniaturization to reduce the invasiveness of implantation procedures. These biologgers are now being applied to other species, and the possibilities seem limitless as technologies continue to advance.

“…Social grooming reduces anxiety because it is linked with the release of rewarding opioid neuropeptide beta-endorphins [45,46] and has been connected with a reduction in heart rate [14,47] and SDB [10,16,22]. We thus included the occurrence of social grooming in the models as it is possible that it influences the likelihood of occurrence of SDB compared to observations where social grooming did not occur.…”

Scratch that itch: revisiting links between self-directed behaviour and parasitological, social and environmental factors in a free-ranging primate

et al. 2016

Different hypotheses explain variation in the occurrence of self-directed behaviour such as scratching and self-grooming: a parasite hypothesis linked with ectoparasite load, an environmental hypothesis linked with seasonal conditions and a social hypothesis linked with social factors. These hypotheses are not mutually exclusive but are often considered separately. Here, we revisited these hypotheses together in female Japanese macaques (Macaca fuscata fuscata) of Kōjima islet, Japan. We input occurrences of scratching and self-grooming during focal observations in models combining parasitological (lice load), social (dominance rank, social grooming, aggression received and proximity), and environmental (rainfall, temperature and season) variables. Using an information-theory approach, we simultaneously compared the explanatory value of models against each other using variation in Akaike's information criterion and Akaike's weights. We found that evidence for models with lice load, with or without environmental–social parameters, was stronger than that for other models. In these models, scratching was positively associated with lice load and social grooming whereas self-grooming was negatively associated with lice load and positively associated with social grooming, dominance rank and number of female neighbours. This study indicates that the study animals scratch primarily because of an immune/stimulus itch, possibly triggered by ectoparasite bites/movements. It also confirms that self-grooming could act as a displacement activity in the case of social uncertainty. We advocate that biological hypotheses be more broadly considered even when investigating social processes, as one does not exclude the other.
