Behavioural synchronisation between different groups of dogs and wolves and their owners/handlers: Exploring the effect of breed and human interaction.

Dogs have previously been shown to synchronise their behaviour with their owner and the aim of this study was to test the effect of immediate interactions, breed, and the effects of domestication. The behavioural synchronisation test was conducted in outdoor enclosures and consisted of 30 s where the owner/handler was walking and 30 s of standing still. Three studies were conducted to explore the effect of immediate interaction (study A), the effect of breed group (study B), and the effect of domestication (study C). In study A, a group of twenty companion dogs of various breeds were tested after three different human interaction treatments: Ignore, Pet, and Play. The results showed that dogs adjusted their movement pattern to align with their owner's actions regardless of treatment. Furthermore, exploration, eye contact, and movement were all influenced by the owners moving pattern, and exploration also decreased after the Play treatment. In study B, the synchronisation test was performed after the Ignore treatment on three groups: 24 dogs of ancient dog breeds, 17 solitary hunting dogs, and 20 companion dogs (data from study A). Irrespective of the group, all dogs synchronised their moving behaviour with their owner. In addition, human walking positively influenced eye contact behaviour while simultaneously decreasing exploration behaviour. In study C, a group of six socialised pack-living wolves and six similarly socialised pack-living dogs were tested after the Ignore treatment. Interestingly, these animals did not alter their moving behaviour in response to their handler. In conclusion, dogs living together with humans synchronise with their owner's moving behaviour, while wolves and dogs living in packs do not. Hence, the degree of interspecies behavioural synchronisation may be influenced by the extent to which the dogs are immersed in everyday life with humans.

Interactions with humans reduce the success of foraging for anthropogenic food by capuchin monkeys (Sapajus libidinosus) in Brasília National Park, Brazil.

The progressive growth of urban environments has increasingly forced populations of nonhuman primates to coexist with humans in many cities, which has resulted in problems such as behavioral alterations, conflicts with humans, and threats to the health of the monkeys, due to their consumption of anthropogenic foodstuffs. These anthropogenic foods, which are rich in calories, are the principal driver of the proximity between humans and primates, even though the acquisition of these foods tends to be risky for the monkeys and involve a variety of challenges derived from specific features of the urban environment. The present study evaluated the success/risk relationship of foraging for anthropogenic food by tufted capuchins (Sapajus libidinosus) in Brasília National Park. The data were analyzed using a binary logistic regression, with the backward-stepwise Wald method, to investigate the factors related to the foraging success of the capuchins, considering variables such as their sex and age, the type of approach and its context, and interactions with humans. The capuchins were influenced by the anthropogenic context, which affected their foraging strategies and diet. Interactions with humans reduced the success of foraging for anthropogenic foods. Conflicts between humans and the capuchins were common, especially in the context of access to food. The capuchins thus preferred to access feeding resources directly, probably due to the reduced human interference, which resulted in greater foraging success for unattended food brought by park visitors and the raiding of trash cans. Based on the observed behavior patterns, a number of measures can be proposed to mitigate these conflicts. These recommendations include not bringing food into areas frequented by the capuchins, not reacting to approaching animals, and removing all trash generated during a visit. A cleaning team dedicated to the maintenance of the visitation area free of anthropogenic waste is also be recommended.

Glucocorticoid response to naturalistic interactions between children and dogs.

Although research has shown that pets appear to provide certain types of social support to children, little is known about the physiological bases of these effects, especially in naturalistic contexts. In this study, we investigated the effect of free-form interactions between children (ages 8-10 years) and dogs on salivary cortisol concentrations in both species. We further investigated the role of the child-dog relationship by comparing interactions with the child's pet dog to interactions with an unfamiliar dog or a nonsocial control condition, and modeled associations between survey measures of the human-animal bond and children's physiological responses. In both children and dogs, salivary cortisol decreased from pre- to post-interaction; the effect was strongest for children interacting with an unfamiliar dog (compared to their pet dog) and for the pet dogs (compared to the unfamiliar dog). We found minimal evidence for associations between cortisol output and behaviors coded from video, but children scoring higher on survey measures of the human-animal bond exhibited the greatest reductions in cortisol when interacting with dogs. Self-reported loneliness was not related to cortisol or the human-animal bond, but measures of both loneliness and the human-animal bond were higher among children who participated after the onset of the COVID-19 pandemic, relative to those who participated before the pandemic. This study builds on previous work that investigated potential stress-buffering effects of human-animal interaction during explicit stressors and demonstrates important physiological correlates of naturalistic interactions between children and dogs, similar to those that occur in daily life.

Cat behaviour in the secure base test: Comparison between owned and shelter animals.

The aim of the present study was to compare affiliative behaviours of owned and shelter cats directed to human in a novel environment after a brief temporary absence of the person. A sample of 20 owned and 20 shelter animals were individually tested in a Secure Base Test, with three 2-min episodes: 1) cat accompanied by a person who sits on the floor inside a circle, 2) the person leaves and the animal is left alone, 3) the person returns, and sits inside the circle again. Three categories were used for coding videotapes of experimental sessions: (1) inside circle, (2) allo-rubbing and (3) tail up. Shelter animals showed more proximity maintenance and affiliative signs with a person than owned animals. Our findings suggested similarities between the secure base effect in cats and in human children: cats seek proximity and maintain contact with a person, displaying affiliative signs to the person, especially after being left alone frightened by an unfamiliar environment.

Culturally determined interspecies communication between humans and honeyguides.

Species interactions that vary across environments can create geographical mosaics of genetic coevolution. However, traits mediating species interactions are sometimes culturally inherited. Here we show that traditions of interspecies communication between people and wild birds vary in a culturally determined geographical mosaic. Honey hunters in different parts of Africa use different calls to communicate with greater honeyguides (Indicator indicator) that lead them to bees' nests. We show experimentally that honeyguides in Tanzania and Mozambique discriminate among honey hunters' calls, responding more readily to local than to foreign calls. This was not explained by variation in sound transmission and instead suggests that honeyguides learn local human signals. We discuss the forces stabilizing and diversifying interspecies communication traditions, and the potential for cultural coevolution between species.

[On the Evolutionary, Bio-Psychological Foundations of the Human-Animal Relationship]. / Zu den evolutionären, bio-psychologischen Grundlagen der Mensch-Tier-Beziehung.

Ever since, people live in contact with nature and animals, even in relatively non-utilitarian ways. Erich Fromm and Edward Wilson termed this human universal "Biophilia". But why different species can live together in a social way, is explained by a "common social toolbox" of neural, psychological and physiologicalmechanisms, which evolved over phylogeny.Major components of this toolbox are found in the vertebrate brain, which evolved over the past 600 million years in a succession of key innovations and conservative preservation.The tegmental and diencephalic brain hosts a 450 million year old, structurally and functionally virtually unchanged "social network" which, in crosstalk with the mammalian prefrontal cortex or the analogous bird forebrain, enables complex social behaviour - within as well as between species. In addition, this toolbox features common principles of behavioural organization, including the expression and reading of emotions, as well as shared emotional, stress and calming systems. Such a common ground for social behaviour also explains the potential effectiveness of animal-assisted interventions in a wide range of pedagogic and therapeutic settings. However, positive effects aremostly revealed by experience and plausibility, whereas studies on animal- assisted activities and interventions according to biomedical scientific standards are still rare.

Mother Nature's playground: Sometimes in the wild it is all about fun.

From surfboard-stealing sea otters to sailboat-chomping killer whales, the summer of 2023 was a landmark year of wild animal antics. Why is wildlife suddenly interacting with humans and their toys in this way? Speculation and headlines have espoused theories about learned behaviors due to enticements with food, increased intrusion, and proximity of humans in wild habitats, as well as aberrant animal responses instigated by oceanic noise or disease-related neurological disorders. However, the most honest answer is, "We don't really know. Maybe the animals are just playing around."

'Pawing' uncertainty! how dogs attenuate the impact of daily hassles at work on uncertainty.

PURPOSE: This study relied on the integrative model of uncertainty tolerance to delineate an argument proposing that daily hassles trigger uncertainty, and this influences adaptive performance. Furthermore, relying on the "furr-recovery method" -where interactions with dogs allow dog owners to recover from negative situations or job demands - this study tested whether having a dog would moderate the relationship between daily hassles and uncertainty. METHODOLOGY: To test this proposed model, daily data during ten working days was gathered with a sample of white-collar workers who were teleworking (N = 233 × 10 = 2,330). FINDINGS: Multilevel results showed that daily hassles influenced adaptive performance via perceived uncertainty. However, the relationship between daily hassles and uncertainty was conditional on the ownership of a dog, in such a way that the relationship became weaker for those who had dogs. That is, those who did not have dogs had increased levels of uncertainty after daily hassles when compared to those who had dogs. PRACTICAL IMPLICATIONS: Managers may consider the adoption of pet-friendly work practices (for instance, telework - working from home allow employees to work nearby and interact with their dogs during worktime) as dogs appear to have a beneficial effect to help employees effectively cope with daily hassles and reduce their uncertain reactions. ORIGINALITY: This study advances knowledge regarding the pawing-effect (the reduced uncertainty to daily hassles on dog owners) on employees' uncertainty to daily hassles and opens new venues for research regarding their role in work-related outcomes. Further, future research could examine how human-dog interactions or the quality of their relationship may benefit owners and explore the benefits of bringing dogs to work periodically.

Companion Animal Fostering as Health Promotion: A Literature Review.

There is growing interest in the health-promoting potential of human-companion animal relationships from a broad public health perspective while acknowledging barriers to ownership, particularly for older adults. Companion animal fostering is an alternative to pet ownership that aligns with the Ottawa Charter health promotion principle that caring for others in everyday settings promotes health. This narrative review of the literature on companion animal fostering draws on Te Whare Tapa Wha (the four-sided house), an indigenous model of health that is influential in Aotearoa/New Zealand, and the Ottawa Charter. We found that companion animal fostering can be considered health-promoting for human and non-human animals, using a broad and multidimensional understanding of health. As well as improving the long-term outcomes for homeless animals, companion animal fostering has the potential to promote the health of the individuals, families, and communities who provide foster homes. Our review highlights the importance of health promoters considering the reciprocal relationship between human and animal health. Future research should explore different aspects of human and non-human health, perspectives of different types of fosterers in different settings and communities, barriers to fostering, and methods that explore the role of caring for a wider range of companion animals in creating and sustaining wellbeing.

Examining human-animal interactions and their effect on multidimensional frailty in later life: a scoping review.

This scoping review sought to compile outcomes associated with any human-animal interaction study regarding adults aged 50 and older in any living context and concerning a multidimensional (i.e., physical, psychological, cognitive, and social) perspective of frailty. Despite our best attempts at incorporating the broadest inclusion criteria possible, only four articles were relevant to this review. Participants across the included studies were rural, community-dwelling Japanese or Chinese individuals aged 60 years and older. Thematic analysis of reported results includes dog ownership as a protective factor regarding frailty, the interconnected health effects of pet ownership, and increased meaning and purpose through pet ownership implications. More research is needed globally to determine how human-animal interactions may moderate frailty comprehensively, as well as the efficacy and appropriateness of these interactions or interventions in older adult populations and across cultural boundaries.

Bird tolerance to humans in open tropical ecosystems.

Animal tolerance towards humans can be a key factor facilitating wildlife-human coexistence, yet traits predicting its direction and magnitude across tropical animals are poorly known. Using 10,249 observations for 842 bird species inhabiting open tropical ecosystems in Africa, South America, and Australia, we find that avian tolerance towards humans was lower (i.e., escape distance was longer) in rural rather than urban populations and in populations exposed to lower human disturbance (measured as human footprint index). In addition, larger species and species with larger clutches and enhanced flight ability are less tolerant to human approaches and escape distances increase when birds were approached during the wet season compared to the dry season and from longer starting distances. Identification of key factors affecting animal tolerance towards humans across large spatial and taxonomic scales may help us to better understand and predict the patterns of species distributions in the Anthropocene.

"There's Something to Remind You that Everything Is Okay": Australian Trans Young People and the Presence of Animals in Interactions With Healthcare Professionals.

While animals have long been a focus in therapeutic spaces for young people via approaches such as animal-assisted therapies, there is a sense in which such approaches overlook the broader contribution that animals play by being present in young people's lives. In this article, we explore how the presence of animals (both physical and psychological) in interactions with healthcare professionals may hold specific meaning for trans young people living in Australia. Participants were recruited through Parents of Gender Diverse Children. Interviews were conducted in November 2021 with 17 trans young people and one of each of their parents living in Australia. All interviews were audio recorded, transcribed, and analyzed using thematic analysis. Two main themes were developed: (1) how healthcare professionals respond to conversations about animals and (2) the beneficial role of the presence of animals. The article concludes by discussing the importance of thinking about the presence of animals beyond existing frameworks and recognizing the value placed on the presence of animals by trans young people.

Still-face Effect in Dogs (Canis familiaris). A Pilot Study.

The Still-face Paradigm has been widely used for the assessment of emotion regulation in infants, as well as for the study of the mother-child relationship. Given the close bond that dogs have with humans, the purpose of this research was to evaluate, through an exploratory descriptive study, the presence of the Still-face effect in dogs. To this end, a group of Beagle dogs were exposed to three one-minute phases in which first, an unknown experimenter interacted actively and positively with each dog (Interaction). Then, suddenly, she interrupted the interaction and remained passive, with a non-expressive face and without speaking or petting the dog (Still-face). Finally, the experimenter reestablished the interaction (Reunion). Our results showed a decrease in affiliative behaviors in dogs during the Still-face phase according to changes in the human's behavior, a pattern similar to the one previously found in infants. Contrary to expectations, no stress-related behaviors were shown during that phase. A carry-over effect was also observed in the Reunion phase. This study provides information about the human-dog interaction and the effects of its disruption on dogs' behaviors.

Horses form cross-modal representations of adults and children.

Recently, research on domestic mammals' sociocognitive skills toward humans has been prolific, allowing us to better understand the human-animal relationship. For example, horses have been shown to distinguish human beings on the basis of photographs and voices and to have cross-modal mental representations of individual humans and human emotions. This leads to questions such as the extent to which horses can differentiate human attributes such as age. Here, we tested whether horses discriminate human adults from children. In a cross-modal paradigm, we presented 31 female horses with two simultaneous muted videos of a child and an adult saying the same neutral sentence, accompanied by the sound of an adult's or child's voice speaking the sentence. The horses looked significantly longer at the videos that were incongruent with the heard voice than at the congruent videos. We conclude that horses can match adults' and children's faces and voices cross-modally. Moreover, their heart rates increased during children's vocalizations but not during adults'. This suggests that in addition to having mental representations of adults and children, horses have a stronger emotional response to children's voices than adults' voices.

Man's best friend(s): Effects of a brief befriending meditation on human-animal relations.

In two studies using samples representative of the US adult population with regard to age, sex and ethnicity, we investigated relationships between loving-kindness and compassion-based practices with speciesism, animal solidarity and desire to help animals. In a cross-sectional study (Study 1, N = 2,822), results showed that past 30 days practice and estimated lifetime number of hours of lovingkindness or compassion meditation were associated with more animal solidarity and greater desire to help animals. Past 30 days practice was also associated with less speciesism, but only when adjusting for sociodemographic characteristics. In an experimental study (Study 2, N = 1,102), results showed that participants randomized to a befriending meditation (a practice similar to loving-kindness and compassion meditation) condition scored higher on animal solidarity and desire to help animals than participants randomized to a control condition. No significant difference was observed on speciesism, but mediation analyses suggested that effects on all three outcomes were mediated through perceived commonality with animals.

Indigenous insights on human-wildlife coexistence in southern India.

As human-wildlife conflicts escalate worldwide, concepts such as tolerance and acceptance of wildlife are becoming increasingly important. Yet, contemporary conservation studies indicate a limited understanding of positive human-wildlife interactions, leading to potentially inaccurate representations of human-animal encounters. Failure to address these limitations contributes to the design and implementation of poor wildlife and landscape management plans and the dismissal of Indigenous ecological knowledge. We examined Indigenous perspectives on human-wildlife coexistence in India by drawing ethnographic evidence from Kattunayakans, a forest-dwelling Adivasi community living in the Wayanad Wildlife Sanctuary in Kerala. Through qualitative field study that involved interviews and transect walks inside the forests, we found that Kattunayakans displayed tolerance and acceptance of wild animals characterized as forms of deep coexistence that involves three central ideas: wild animals as rational conversing beings; wild animals as gods, teachers, and equals; and wild animals as relatives with shared origins practicing dharmam. We argue that understanding these adequately will support efforts to bring Kattunayakan perspectives into the management of India's forests and contribute to the resolution of the human-wildlife conflict more broadly.

Conocimiento Originario sobre la Coexistencia entre Humanos y Fauna en el Sur de la India ResumenConforme el conflicto humano-fauna escala a nivel mundial, los conceptos como la tolerancia y aceptación de la fauna son cada vez más importantes. Aun así, los estudios actuales sobre conservación muestran un conocimiento limitado de las interacciones positivas entre los humanos y la fauna, lo que lleva a representaciones potencialmente erróneas de los encuentros entre estos dos grupos. Las fallas al abordar estas limitaciones contribuyen al diseño e implementación de planes deficientes de manejo de fauna y paisajes y la desestimación del saber ecológico de los pueblos originarios. Analizamos las perspectivas de los pueblos originarios sobre la coexistencia entre las personas y la fauna en la India mediante la toma de evidencia etnográfica de los Kattunayakans, una comunidad Adivasi residente del bosque en el Santuario de Fauna Wayanad en Kerala. Realizamos un estudio cualitativo de campo con entrevistas y caminatas por transectos dentro del bosque. Con el estudio descubrimos que los Kattunayakans demostraron una tolerancia y aceptación por los animales silvestres caracterizada como maneras de coexistencia profunda que involucra tres ideas centrales: los animales silvestres son seres hablantes racionales; los animales como divinidades, maestros e iguales; y los animales silvestres como familiares practicantes del dharmam con orígenes compartidos. Argumentamos que el entendimiento de estas ideas centrales respaldará los esfuerzos por incorporar las perspectivas de los Kattunayakan a la gestión forestal de la India y contribuirá a grandes rasgos a la solución del conflicto humano-fauna.
