  Title Behavioural correlation of heart rate changes in family dogs Type Journal Article
  Year 2008 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.  
  Volume 109 Issue 2 Pages 329-341  
  Keywords  
  Abstract Fourteen dogs (7 males and 7 females) were tested for their heart rate (HR) and heart rate variability (HRV) responses in different activities and environmental challenges while their movement was controlled. First, we wanted to compare the dogs? cardiac responses in different body positions (lying, sitting and standing) and during slow walking to reveal their possible influence on HR and HRV. Second, we tested the HR response during an attentive state when the dog was gazing at its favourite toy while remaining in a steady body position. Finally we investigated the heart activity during separation from the owner. We also analysed the individual differences and the influence of gender on the heart responses. We found that the HR increased during periods of increased activity (walking) and was lowest during lying, while it did not differ between sitting and standing. At the same time no changes in HRV were found in the case of different body positions and walking. In contrast, HRV significantly increased when dogs oriented towards their favourite toy, and we found a distinct individual characteristic HR change in this situation compared to the similar body position without the toy being shown. Interestingly during separation from the owner the HR did not increase, but when a strange person was petting the dog, a significant increasing effect was seen in the HR. However the HRV increased only when the petting was discontinued. In general, large individual variation was found with regard to the HR and HRV, while gender did not influence the cardiac activity of the dogs.These results show that body position affected HR significantly in dogs. Further it seems that HRV could be a good indicator of the dog's attentive state. Thus in future studies both the physical and cognitive factors should be given more attention when HR or HRV is investigated as a dependent variable.

  Title Social learning strategies and predation risk: minnows copy only when using private information would be costly Type Journal Article
  Year 2008 Publication Proc Biol Sci Abbreviated Journal Proc. R. Soc. Lond. B  
  Volume 275 Issue 1653 Pages 2869-2876  
  Keywords  
  Abstract Animals can acquire information from the environment privately, by sampling it directly, or socially, through learning from others. Generally, private information is more accurate, but expensive to acquire, while social information is cheaper but less reliable. Accordingly, the 'costly information hypothesis' predicts that individuals will use private information when the costs associated with doing so are low, but that they should increasingly use social information as the costs of using private information rise. While consistent with considerable data, this theory has yet to be directly tested in a satisfactory manner. We tested this hypothesis by giving minnows (Phoxinus phoxinus) a choice between socially demonstrated and non-demonstrated prey patches under conditions of low, indirect and high simulated predation risk. Subjects had no experience (experiment 1) or prior private information that conflicted with the social information provided by the demonstrators (experiment 2). In both experiments, subjects spent more time in the demonstrated patch than in the non-demonstrated patch, and in experiment 1 made fewer switches between patches, when risk was high compared with when it was low. These findings are consistent with the predictions of the costly information hypothesis, and imply that minnows adopt a 'copy-when-asocial-learning-is-costly' learning strategy.

  Title Systematic Review of the Empirical Evidence of Study Publication Bias and Outcome Reporting Bias Type Journal Article
  Year 2008 Publication Plos One Abbreviated Journal Plos One  
  Volume 3 Issue 8 Pages e3081  
  Keywords  
  Abstract Background The increased use of meta-analysis in systematic reviews of healthcare interventions has highlighted several types of bias that can arise during the completion of a randomised controlled trial. Study publication bias has been recognised as a potential threat to the validity of meta-analysis and can make the readily available evidence unreliable for decision making. Until recently, outcome reporting bias has received less attention. Methodology/Principal Findings We review and summarise the evidence from a series of cohort studies that have assessed study publication bias and outcome reporting bias in randomised controlled trials. Sixteen studies were eligible of which only two followed the cohort all the way through from protocol approval to information regarding publication of outcomes. Eleven of the studies investigated study publication bias and five investigated outcome reporting bias. Three studies have found that statistically significant outcomes had a higher odds of being fully reported compared to non-significant outcomes (range of odds ratios: 2.2 to 4.7). In comparing trial publications to protocols, we found that 40-62% of studies had at least one primary outcome that was changed, introduced, or omitted. We decided not to undertake meta-analysis due to the differences between studies. Conclusions Recent work provides direct empirical evidence for the existence of study publication bias and outcome reporting bias. There is strong evidence of an association between significant results and publication; studies that report positive or significant results are more likely to be published and outcomes that are statistically significant have higher odds of being fully reported. Publications have been found to be inconsistent with their protocols. Researchers need to be aware of the problems of both types of bias and efforts should be concentrated on improving the reporting of trials.

  Title Preliminary investigations into the ethological relevance of round-pen (round-yard) training of horses Type Journal Article
  Year 2008 Publication Journal of Applied Animal Welfare Science Abbreviated Journal  
  Volume 11 Issue 3 Pages 285-298  
  Keywords  
  Abstract Recently, training horses within round-pens has increased in popularity. Practitioners often maintain that the responses they elicit from horses are similar to signals used with senior conspecifics. To audit the responses of horses to conspecifics, 6 mare-young-horse dyads, this study introduced them to each other in a round-pen and videoed them for 8 min. These dyads spent significantly more time farther than 10 m apart than they did less than 1 m apart (p < .001). The time they spent less than 1 m apart decreased over the 8-min test period (p = .018). Mares occupied the center of the round-pen and chased youngsters for 0.73% of the test period (p < .001). Mares made all agonistic approaches (p < .001), and youngsters (p = .018) made all investigative approaches. Head lowering and licking-and-chewing were exhibited most when the youngsters were facing away from the mares (p < .001). The frequency of head lowering increased during the test period (p = .027), whereas the frequency of licking-and-chewing did not change. The results bring into question the popular interpretation and ethological relevance of equine responses commonly described in round-pen training and show that mares did not condition young horses to remain in close proximity to them.
