The international governing body for equestrian sports, the Fédération Equestre Internationale (FEI), states that the welfare of the horse must be paramount and never subordinated to competitive or commercial influences. However, there is growing unease about welfare issues from both within and outside the sport. The aim of this study was to understand stakeholder perceptions of current welfare issues within equestrian sport, determine whether there is scope for change, and explore attitudes towards welfare assessment. Participants (n = 48) from equestrian sport (n = 38) and animal welfare research (n = 10) attended a workshop that included welfare-related presentations and focus group sessions. The focus group sessions were recorded, anonymised and analysed using thematic analysis. Conflict between the demands of competition and the needs of the horse was identified as a key welfare challenge. Although the physical health of equine athletes is closely monitored, horses’ psychological needs are sometimes overlooked. Participants recognised that improving competition practices may not be as impactful as improving the general management and training of horses. The term “quality of life” was considered preferable to “welfare”, which had negative connotations. Participants appreciated the idea of incorporating formal welfare assessments into their training and competition plans but stated that existing tools are rarely used and are not deemed feasible for real-life conditions.

Population growth near protected areas threatens the capacity of such areas for biodiversity conservation. Protected areas may even encourage growth by providing economic benefits that attract migrants. Consequently, understanding the relationships between human demographics and biodiversity is important for conservation. We studied a community-governed Wildlife Management Area bordering the Selous Game Reserve in Tanzania, set up to benefit local people and the subsistence rural economy. Annual population growth in this area is 5%. We used a combination of ecological and socio-economic surveys to determine the causes of this growth and its effect on wildlife in the Wildlife Management Area. One-third of local people interviewed were immigrants to the area. Population growth appeared to be unrelated to the protected area; instead an increasing proportion of immigrants cited readily available land as their reason for moving. Pastoralism was associated with fewer signs of large grazing mammals and elephants Loxodonta africana and agriculture was associated with fewer signs of elephant and buffalo Syncerus caffer but more signs of other ungulates. Few residents were aware of the Wildlife Management Area and few received any benefits from wildlife and therefore had little reason to conserve it. This situation is attributable to poor management of the Wildlife Management Area. Detrimental effects of human activity could spread to the Selous Game Reserve if population growth continues. However, natural resources could benefit residents if properly managed. Interactions between human demographics and protected areas are complex and may be best managed on a case-by-case basis.

The role that working equids play in both rural and urban communities in low and middle-income countries is invaluable. They contribute to daily tasks such as carrying food, water and people, support income generation, and are of social and cultural importance. Despite their importance, global standards of working equid welfare are low. Many variables can impact the welfare status of animals under human care, but often specific factors are explored in isolation. Factors can include, but are not limited to an owner’s socioeconomic status and their attitudes and beliefs towards animals. In this study we assessed the relationships between 1.) Attitudes and belief in horse sentience, 2.) Owner’s socioeconomic status (including household income, coverage of needs and education) and 3.) Horse welfare status. The study, consisting of an owner questionnaire and a welfare assessment of their horses, was conducted in three regions in Senegal; participants included 299 owners and their horses. Overall, our findings show that a more positive attitude towards horses, stronger belief in horse sentience, a higher standard of living and a greater ability to cover the needs of the household was associated with more positive horse welfare. A stronger belief in horse sentience was a significant predictor of horse’s body condition, larger households and those with a higher income were more likely to own a horse in good general health. Our findings demonstrate a complex relationship between working horse welfare, their owner’s attitudes, and their socioeconomic status. It is the first study we are aware of that has explored the relationships between these different variables. The findings from this study provide valuable insights into the interconnected factors which impact upon working equid welfare in Senegal and potentially more widely.

The ability to discriminate between emotion in vocal signals is highly adaptive in social species. It may also be adaptive for domestic species to distinguish such signals in humans. Here we present a playback study investigating whether horses spontaneously respond in a functionally relevant way towards positive and negative emotion in human nonverbal vocalisations. We presented horses with positively- and negatively-valenced human vocalisations (laughter and growling, respectively) in the absence of all other emotional cues. Horses were found to adopt a freeze posture for significantly longer immediately after hearing negative versus positive human vocalisations, suggesting that negative voices promote vigilance behaviours and may therefore be perceived as more threatening. In support of this interpretation, horses held their ears forwards for longer and performed fewer ear movements in response to negative voices, which further suggest increased vigilance. In addition, horses showed a right-ear/left-hemisphere bias when attending to positive compared with negative voices, suggesting that horses perceive laughter as more positive than growling. These findings raise interesting questions about the potential for universal discrimination of vocal affect and the role of lifetime learning versus other factors in interspecific communication.

Living in complex societies is thought to promote the development of sophisticated social, cognitive, and communicative skills. Investigating the extent of these skills across taxa is critical to understanding the evolution of the advanced abilities found in some species, including humans. Facial expressions are rich sources of social information for humans and some primates; however whether this is true for other animals is largely unknown. Horses are an ideal study species for these questions: they form valuable social relationships and display some advanced socio-cognitive skills, but are phylogenetically distant from primates and so might be expected to communicate quite differently. Here I present a method for quantifying and coding horse facial movements (EquiFACS), which reveals that horses have an extensive capacity for producing facial expressions. I then utilise EquiFACS to demonstrate that horses produce facial actions that mirror the emotional content of auditory stimuli, providing evidence for a perception-action representation of emotional information. Through my experiments on the perception of facial expressions in horses I show that these expressions display meaningful information to conspecifics, which influences their behaviour in functionally relevant ways. I also shed light on the physiological processes involved in the perception of emotional conspecific facial expressions, showing that viewing negatively valenced conspecific emotional expressions raises resting heart rate. This is indicative of emotional contagion, which may be a mechanism through which information is obtained and social interactions are regulated. Collectively, my research demonstrates the ability to produce and use complex facial expressions as a source of social information is not limited to primates, but is present in at least two phylogenetically distant groups. This suggests these skills may either be an evolutionarily conserved trait or have evolved under common selective pressures. As well as their scientific significance, these findings have implications for horse management and welfare.
