Title Show me your best side: Lateralization of social and resting behaviors in feral horses Type Journal Article
Year 2023 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume 206 Issue Pages 104839
Keywords (down) Cerebral lateralization; Drone technology; ; Hemispheric specialization; Horses; Social interactions
Abstract Growing evidence shows a variety of sensorial and motor asymmetries in social and non-social interactions in various species, indicating a lateralized processing of information by the brain. Using digital video cameras on tripods and drones, this study investigated lateralization in frequency and duration of social behavior patterns, in affiliative, agonistic, and resting contexts, in a feral population of horses (Equus ferus caballus) in Northern Portugal, consisting of 37 individuals organized in eight harem groups. Affiliative interactions (including grooming) were more often performed, and lasted longer, when recipients were positioned to the right side. In recumbent resting (animals lying down) episodes on the left side lasted longer. Our results of an affiliative behavior having a right side tendency, provide partial support to the valence-specific hypothesis of Ahern and Schwartz (1979) – left hemisphere dominance for positive affect, affiliative behaviors. Longer recumbent resting episodes on the left side may be due to synchronization. However, in both instances it is discussed how lateralization may be context dependent. Investigating the position asymmetries of social behaviors in feral equids will contribute to a better understanding of differential lateralization and hemispheric specialization from the ecological and evolutionary perspectives.

Title Emotional reactions to learning in cattle Type Journal Article
Year 2004 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 85 Issue 3 Pages 203-213
Keywords (down) Cattle; Expressive behaviour; Operant learning; Reinforcer
Abstract It has been suggested that during instrumental learning, animals are likely to react emotionally to the reinforcer. They may in addition react emotionally to their own achievements. These reactions are of interest with regard to the animals' capacity for self-awareness. Therefore, we devised a yoked control experiment involving the acquisition of an operant task. We aimed to identify the emotional reactions of young cattle to their own learning and to separate these from reactions to a food reward. Twelve Holstein-Friesian heifers aged 7-12 months were divided into two groups. Heifers in the experimental group were conditioned over a 14-day period to press a panel in order to open a gate for access to a food reward. For heifers in the control group, the gate opened after a delay equal to their matched partner's latency to open it. To allow for observation of the heifers' movements during locomotion after the gate had opened, there was a 15m distance in the form of a race from the gate to the food trough. The heart rate of the heifers, and their behaviour when moving along the race towards the food reward were measured. When experimental heifers made clear improvements in learning, they were more likely than on other occasions to have higher heart rates and tended to move more vigorously along the race in comparison with their controls. This experiment found some, albeit inconclusive, indication that cattle may react emotionally to their own learning improvement.

Title The effectiveness of livestock protection measures against wolves (Canis lupus) and implications for their co-existence with humans Type Journal Article
Year 2020 Publication Global Ecology and Conservation Abbreviated Journal
Volume 21 Issue Pages e00868
Keywords (down) Carnivore; Depredation; Efficiency; Germany; Intervention; Predator
Abstract Wolves (Canis lupus) can kill domestic livestock resulting in intense conflicts with humans. Damage to livestock should be reduced to facilitate human-wolf coexistence and ensure positive outcomes of conservation efforts. Current knowledge on the effectiveness of livestock protection measures from wolves is limited and scattered in the literature. In this study, we compiled a dataset of 30 cases describing the application of 11 measures of protecting cattle and smaller livestock against wolves, estimated their effectiveness as a relative risk of damage, and identified the best measures for damage reduction. We found that: (1) lethal control and translocation were less effective than other measures, (2) deterrents, especially fladry which is a fence with ropes marked by hanging colored flags that sway in the wind and provide a visual warning signal, were more effective than guarding dogs; (3) deterrents, fencing, calving control and herding were very effective, but the last two measures included only one case each; and (4) protection of cattle was more effective than that of small stock (sheep and goats, or sheep only) and mixed cattle and small stock. In all of these cases, the relative risk of damage was reduced by 50-100%. Considering Germany as an example of a country with a recovering wolf population and escalating human-wolf conflicts, we suggest electric fences and electrified fladry as the most promising measures, which under suitable conditions can be accompanied by well-trained livestock guarding dogs, and the temporary use of deterrents during critical periods such as calving and lambing seasons. Further research in this field is of paramount importance to efficiently mitigate human-wolf conflicts.

Title Does Music Influence Emotional State in Race Horses? Type Journal Article
Year 2015 Publication Journal of Equine Veterinary Science Abbreviated Journal
Volume 35 Issue 8 Pages 650-656
Keywords (down) Cardiac activity; Emotional state; Music; Race horse
Abstract The aim of the study was to determine the effect of music featured in the barn, on the emotional state of race horses. Seventy 3-year-old Purebred Arabian horses in their first race season were divided into experimental group (EXP) of 40 horses and control group (CNT) of 30 horses and placed in separate barns. The EXP was subject to specifically composed music featured in the barn for 5 hours in the afternoon during the whole study. The emotional state in the horses was assessed at rest, saddling, and warm-up walk under rider. Measurements were taken six times, every 30 to 35 days, starting from the beginning of featuring the music. The horse's emotional state was assessed by cardiac activity variables. The music effect on the emotional state was also considered with regard to the horse's performance estimated by race records. The cardiac activity variables were compared with repeated measures design, whereas race records were analyzed with analysis of variance generalized linear model. The music positively affected the emotional state in race horses. The influence was noticeable already after the first month of featuring the music and increased in the second and third months. Despite the fact that later the variables began to return to initial levels, a positive effect of the music on prizes won by the horses in the EXP compared to the CNT was found (P < .05). The results suggest that the music may be featured in the barn, preferably for 2 to 3 months as a means of improving the welfare of race horses.

Title Military training areas facilitate the recolonization of wolves in Germany Type Journal Article
Year 2019 Publication Conservation Letters Abbreviated Journal Conservation Letters
Volume 12 Issue 3 Pages e12635
Keywords (down) Canis lupus; large carnivores; population growth; protected areas; recolonization
Abstract Abstract Wolves (Canis lupus) are currently showing a remarkable comeback in the highly fragmented cultural landscapes of Germany. We here show that wolf numbers increased exponentially between 2000 and 2015 with an annual increase of about 36%. We demonstrate that the first territories in each newly colonized region were established over long distances from the nearest known reproducing pack on active military training areas (MTAs). We show that MTAs, rather than protected areas, served as stepping-stones for the recolonization of Germany facilitating subsequent spreading of wolf territories in the surrounding landscape. We did not find any significant difference between MTAs and protected areas with regard to habitat. One possible reason for the importance of MTAs may be their lower anthropogenic mortality rates compared to protected and other areas. To our knowledge, this is the first documented case where MTAs facilitate the recolonization of an endangered species across large areas.

Title A Review of Wolf Predation in Southern Europe: Does the Wolf Prefer Wild Prey to Livestock? Type Journal Article
Year 1996 Publication Journal of Applled Ecology Abbreviated Journal J. Appl. Ecol
Volume 33 Issue Pages 1561-1571
Keywords (down) Canis lupus, conservation, food habits, prey abundance, prey availability.
Abstract 1. The recent recovery of the wolf in southern Europe has not yet removed the risk

of local extinction. Wolf populations are fragmented and often comprise fewer than

500 individuals. In North America, northern and eastern Europe, wolves feed maiiily

on wild herbivores. In southern Europe, this canid has apparently adapted to feed

also on fruit, rubbish, livestock, small and medium-size mammals.

2. The main conservation problem lies with predation o n domestic ~ingulates,w liich

leads to extensive killing of wolves. The reintroduction of wild large herbivores has

been advocated as a means of reducing attacks on livestock, but predatiori on the

latter may remain high if domestic ungulates are locally abundant.

3. Our synthesis of 15 studies, published in the last 15 years, on food habits of the

wolf in southern Europe, has shown that ungulates have been the main diet component

overall. A significant inverse correlation was found between the occurrence (%) of

wild and domestic ungulates in the diet. The presence of relatively few wild ungulate

species was necessary to reduce predation on livestock.

4. Selection of wild and domestic ungulate prey was influenced mainly by their local

abundance, but also by their accessibility. Feeding dependence on rubbish was local

and rare. In Italy, the consumption of riibbish/fruit and that of ungulates was significantly

negatively correlated. Diet breadth increased as the presence of large prey

in tlie diet decreased.

5. The simultaneous reintroduction of severa1 wild ungulate species is likely to reduce

predation on livestock and may prove to be one of the most effective conservation

measures.

Title The Acoustic Structure Of Wolf Howls In Some Eastern Tuscany (Central Italy) Free Ranging Packs Type Journal Article
Year 2010 Publication Bioacoustics Abbreviated Journal Bioacoustics
Volume 19 Issue 3 Pages 159-175
Keywords (down) Canis lupus, acoustic structure, mammal communication, sonogram, fundamental frequency.
Abstract Italian wolf howls are described for the first time from observations between 2003–2008 of a population living in eastern Tuscany, central Italy. A sample of 37 howls selected among single responses and 128 howls included in the choruses of 7 free ranging packs was recorded and analysed. The mean fundamental frequency of the howls ranged between 274–908 Hz. Two main structures recognised by means of multivariate explorative analysis, in particular Principal Component and Cluster Analysis, were ascribed to breaking and flat howls. Discriminant Function Analysis was applied to the recognised groups with the aim to find a general rule for classification. Howls with different features were correctly assigned to the groups obtained by explorative analysis in 95.8% of cases. The analysis of the variables characterising the structure of the howls suggests that maximum frequency and range of fundamental frequency are the most important parameters for classification, while duration does not appear to play any significant role.

Title The pitfalls of wildlife camera trapping as a survey tool in Australia Type Journal Article
Year 2015 Publication Australian Mammalogy Abbreviated Journal Aust. Mammal.
Volume 37 Issue 1 Pages 13-22
Keywords (down) camera trap constraints, critical review, remote cameras.
Abstract Camera trapping is a relatively new addition to the wildlife survey repertoire in Australia. Its rapid adoption has been unparalleled in ecological science, but objective evaluation of camera traps and their application has not kept pace. With the aim of motivating practitioners to think more about selection and deployment of camera trap models in relation to research goals, we reviewed Australian camera trapping studies to determine how camera traps have been used and how their technological constraints may have affected reported results and conclusions. In the 54 camera trapping articles published between 1991 and 2013, mammals (86%) were studied more than birds (10%) and reptiles (3%), with small to medium-sized mammals being most studied. Australian camera trapping studies, like those elsewhere, have changed from more qualitative to more complex quantitative investigations. However, we found that camera trap constraints and limitations were rarely acknowledged, and we identified eight key issues requiring consideration and further research. These are: camera model, camera detection system, camera placement and orientation, triggering and recovery, camera trap settings, temperature differentials, species identification and behavioural responses of the animals to the cameras. In particular, alterations to animal behaviour by camera traps potentially have enormous influence on data quality, reliability and interpretation. The key issues were not considered in most Australian camera trap papers and require further study to better understand the factors that influence the analysis and interpretation of camera trap data and improve experimental design.

Title Gender and Equestrian Sport Type Book Whole
Year 2013 Publication Abbreviated Journal
Volume Issue Pages
Keywords (down) British Equestrian Sport Canadian Show Jumping Cojones and Rejones Comparative Analysis Equestrian World through a Gender Lens Equestrianism during the 20th Century Fluid Masculinities on Brazilian Dressage Gender Studies and Equestrian Sport Horseracing and Gender in the United Kingdom Juvenile Equine Fiction for Girls Men and Horse Riding Spanish Mounted Bullfight Sport and Culture Swedish Equestrian Sports Women Riding Rodeo in Southern Brazil Women in Equestrian Polo
Abstract This volume brings together studies from various disciplines of the social sciences and humanities (Anthropology, Sociology, Cultural Studies, History and Literary theory) that examine the equestrian world as a historically gendered and highly dynamic field of contemporary sport and culture. From elite international dressage and jumping, polo and the turf, to the rodeo world of the Americas and popular forms of equestrian sport and culture, we are introduced to a range of issues as they unfold at local and global, national and international levels. Students and scholars of gender, culture and sport will find much of interest in this original look at contemporary issues such as “engendered” (women’s and men’s) dentities/subjectivities of equestrians, representations of girls, horses and the world of adventure in juvenile fiction; the current “feminization” of particular equestrian activities (and where boys and men stand in relation to this); how broad forms of social inequality and stratification play themselves out within gendered equestrian contexts; men and women and their relation to horses within the framework of current discussions on the relation of animals to humans (which may include not only love and care, but also exploitation and violence), among others. Singular contributions that incorporate a wide variety of classic and contemporary theoretical perspectives and empirical methodologies show how horse cultures around the globe contribute to historical and current constructions of embodied “femininities” and “masculinities”, reflecting a world that has been moving “beyond the binaries” while continuing to be enmeshed in their persistent and contradictory legacy. The final chapter makes a brave attempt at synthesizing individual chapters and moving forward from the evidences they provide, to suggest a compelling agenda for future research.

Volume 6 Issue 5 Pages 178-190
Keywords (down) brain size – neocortex – social brain hypothesis – social skills – mind reading – primates
Abstract Conventional wisdom over the past 160 years in the cognitive and neurosciences has assumed that brains evolved to process factual information about the world. Most attention has therefore been focused on such features as pattern recognition, color vision, and speech perception. By extension, it was assumed that brains evolved to deal with essentially ecological problem-solving tasks. © 1998 Wiley-Liss, Inc.
