Abstract |
Poaching is a widespread and well-appreciated problem for the conservation of many threatened species. Because poaching is illegal, there is strong incentive for poachers to conceal their activities, and consequently, little data on the effects of poaching on population dynamics are available. Quantifying poaching mortality should be a required knowledge when developing conservation plans for endangered species but is hampered by methodological challenges. We show that rigorous estimates of the effects of poaching relative to other sources of mortality can be obtained with a hierarchical state-space model combined with multiple sources of data. Using the Scandinavian wolf (Canis lupus) population as an illustrative example, we show that poaching accounted for approximately half of total mortality and more than two-thirds of total poaching remained undetected by conventional methods, a source of mortality we term as 'cryptic poaching'. Our simulations suggest that without poaching during the past decade, the population would have been almost four times as large in 2009. Such a severe impact of poaching on population recovery may be widespread among large carnivores. We believe that conservation strategies for large carnivores considering only observed data may not be adequate and should be revised by including and quantifying cryptic poaching. |

Abstract |
Twelve yearlings were divided into two groups and subjected to two different training schedules: (a) 30min of training daily (the daily trained group); and (b) 30min of training for 4 days, followed by a 3-day rest (the intermittently trained group), in order to compare the effect of two training methods on the ability of the horses to learn to be driven and ridden and to respond to the handlers? cues. The length of this experimental training was 17 days. The first step of training was surcingling and proceeded to lunging, to driving from the ground, and finally to being ridden at a trot on a track. Both groups were tested four times during the experimental period when they were at the same stage of training. They were driven and then ridden at a walk by a rider on a specified course and evaluated. The time to complete the course, accuracy of traveling the course, and heart rate during the test were used as the indicators of success in training. In three out of the four tests, the daily trained group tended to move faster and with more accuracy than the intermittently trained group. It would appear that daily training without a long interruption is more effective for yearlings. |

Abstract |
This study explored the relationship between two creative styles (adaptor and innovator) and the Big Five personality traits (extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience). 164 teachers from 3 secondary and 2 primary schools in Singapore completed a self?report questionnaire, which consisted of the Kirton Adaption?Innovation Inventory and the NEO?Five Factor Inventory. It was found that adaptors were significantly more conscientious than innovators, while innovators were significantly more extraverted and open to experience than adaptors. No significant differences were found between adaptors and innovators in neuroticism and agreeableness. The study also revealed a meaningful pattern of relationships between the Big Five personality traits and the three facet scales of the KAI. Specifically, Sufficiency of Originality was negatively correlated with Openness to Experience and Extraversion; Rule Governance was positively correlated with conscientiousness but negatively correlated with openness to experience; Efficiency was positively correlated with conscientiousness. The overall findings supported the fundamental contention that different creative styles were due to different combinations of personality traits, with adaptors being more conscientious, while innovators being more extraverted and open to experience. These personality?based differences in creative styles between adaptors and innovators had resulted in much social conflict between them. One way of resolving it is to make known the nature and value of different creative styles to these two different types of creators. |

Abstract |
Many studies have been carried out into both motor and sensory laterality of horses in agonistic and stressful situations. Here we examine sensory laterality in affiliative interactions within four groups of domestic horses and ponies (N = 31), living in stable social groups, housed at a single complex close to Vienna, Austria, and demonstrate for the first time a significant population preference for the left side in affiliative approaches and interactions. No effects were observed for gender, rank, sociability, phenotype, group, or age. Our results suggest that right hemisphere specialization in horses is not limited to the processing of stressful or agonistic situations, but rather appears to be the norm for processing in all social interactions, as has been demonstrated in other species including chicks and a range of vertebrates. In domestic horses, hemispheric specialization for sensory input appears not to be based on a designation of positive versus negative, but more on the perceived need to respond quickly and appropriately in any given situation. |

Abstract |
Context: It is argued in self-determination theory that the motivation underlying behavior has implications for health and well-being independent of the behavior itself. Objective: To examine associations between athlete motivations for returning to sport after injury and perceived psychological return-to-sport outcomes. Design: A correlational survey design was employed to obtain data in Canada, Australia, and England. Participants: Elite and subelite athletes (N = 180) with injuries requiring a minimum 2-month absence from sport participation. Main Outcome Measures: Participants completed an inventory measuring perceptions of motivation to return to sport from a serious injury and psychological return-to-sport outcomes. Results: Correlational analyses revealed that intrinsic motivations for returning to competition were associated with a positive renewed perspective on sport participation. Conversely, extrinsic motivations for returning to sport were associated with increased worry and concern. Conclusions: The motivation underlying return to sport might play an important role in return-to-sport perceptions among elite and subelite athletes. |

Abstract |
Humans have domesticated many kinds of animals in their history. Dogs and horses have particularly close relationships with humans as cooperative partners. However, fewer scientific studies have been conducted on cognition in horses compared to dogs. Studies have shown that horses cross-modally distinguish human facial expressions and recognize familiar people, which suggests that they also cross-modally distinguish human emotions. In the present study, we used the expectancy violation method to investigate whether horses cross-modally perceive human emotions. Horses were shown a picture of a human facial expression on a screen, and they then heard a human voice from the speaker before the screen. The emotional values of the visual and auditory stimuli were the same in the congruent condition and different in the incongruent condition. Horses looked at the speaker significantly longer in the incongruent condition than in the congruent condition when they heard their caretaker's voices but not when they heard the stranger voice. In addition, they responded significantly more quickly to the voice in the incongruent condition than in the congruent one. To the best of our knowledge, this is the first study to show that horses cross-modally recognized the emotional states of their caretakers and strangers. |

Abstract |
Während die traditionellen Pferdesportdisziplinen Dressur- und Springreiten Mitglieder verlieren, haben sich weitere Pferdesportarten in Deutschland etabliert und erfreuen sich wachsender Beliebtheit. Die vorliegende Arbeit beschäftigt sich mit den Hintergründen dieser Entwicklung. In einer empirischen Untersuchung wurden 1814 Reiter zu ihren Reitmotiven befragt. Mit Hilfe von Hauptkomponenten- und Clusteranalyse wurde eine Typologie gebildet, die ein differenziertes Bild der Motive verschiedener Reitergruppen ermöglicht. Während die leistungsorientierten Reiter eher in klassischen Reitsportdisziplinen vertreten sind, dominieren in moderneren Reitsportdisziplinen vor allem Genussmotive. Insgesamt entwickelt sich der Trend im Reitsport deutlich vom Drill in der Reitbahn hin zu mehr Entspannung, Erholung und Selbstverwirklichung. Der Wunsch, in der Freizeit Leistung zu bringen, sich mit anderen zu messen und Erfolg zu haben, ist nur noch für einen kleineren Teil der Pferdesportler bedeutsam. Aus der Verteilung der Motive ergeben sich neue Herausforderungen für den organisierten Reitsport, um den Spagat zwischen den Anforderungen der leistungsorientierten Sportreiter und den Erholungssuchenden zu meistern. |

AbstractThe last two decades have seen a virtual explosion in empirical research on the role of social interactions in the development of animals' behavioral repertoires, and a similar increase in attention to formal models of social learning. Here we first review recent empirical evidence of social influences on food choice, tool use, patterns of movement, predator avoidance, mate choice, and courtship, and then consider formal models of when animals choose to copy behavior, and which other animals' behavior they copy, together with empirical tests of predictions from those models. |

Abstract |
The social and spatial organization of urban fox groups prior to and during an outbreak of sarcoptic mange was compared with predictions derived from the resource dispersion hypothesis (RDH). We investigated the availability of three key resources. Neither daytime rest sites nor breeding sites appeared to be limited in availability. The availability of food deliberately supplied by local householders was examined by questionnaire surveys. The daily and weekly amount of food supplied was greatly in excess of the minimum requirements of a pair of foxes, but was consistent between territories. The availability of this food source increased markedly as a result of more people feeding the foxes. In agreement with the RDH, group size prior to the outbreak of mange increased from 2.25 animals (N=4) to 6.57 animals (N=7). Before the outbreak of mange, two territories were divided. Increased scavenge availability on smaller territories may have promoted these changes. Excluding these spatial changes, territories were very stable between years. After the outbreak of mange, group size declined as a direct result of mange-induced mortality. Surviving animals increased their ranges only after neighbouring groups had died out. Ranges did not increase in size in response to a decline in food availability. Nor were the increases in range size associated with the relinquishment of parts of the existing territory. These postmange changes are contrary to the RDH. Three factors may have promoted these changes: the elimination of interstitial space, the forced dispersal of young or future division of the territory. |
