Studies on environmental enrichment for reptiles are lacking in the scientific literature. Although the literature reflects a limited take on reptile enrichment in the zoological community, it may not be the case in reality as enrichment is generally considered an important aspect of the care of nonhuman animals in captivity. This project investigated the current state of reptile enrichment as it is being used in zoos. Although respondents were disproportionately accredited by the Association of Zoos and Aquariums, the results showed many forms of enrichment being used for reptiles in zoos and happening at much greater levels than what has been suggested in the scientific literature. There were significant differences between a) reptile groups for each form of enrichment, and b) enrichment forms within each reptile group, except with the use of natural enrichment devices and structural/habitat design, which did not differ across all reptile groups. Enrichment goals, assessment methods, and sources of information for reptile enrichment used by zoos suggest the need for more scientific publications for facilities to make evidence-based decisions to improve the welfare of reptiles in captivity. 相似文献

Gender plays a significant role in influencing people's attitudes toward animals, however, little is known about how it influences their attribution of emotions to animals. To investigate the role that gender plays in public attitudes toward animals' experience of emotions and beliefs about whether animals can grieve, a face-to-face survey of 1,000 members of the general public was carried out in Brisbane, Australia. Potential respondents were asked to complete a 10-min “social attitudinal” survey. Males were significantly less likely than females to believe that animals experience complex emotions, including depression (p < 0.05), anxiety (p < 0.05), love (p < 0.01), and grief (p < 0.05), but did not differ in regard to basic emotions including distress, fear, happiness, anger, sadness, and fear. Males were also less likely to believe that animals show some behavioral (eating p < 0.05; vocalizing p < 0.01) changes when they experience grief (p < 0.05) and that animals grieve as a result of separation from a conspecific (p < 0.005). These results demonstrate a greater skepticism in males, compared with females, regarding the attribution of emotions to animals. 相似文献

Expanding on studies of the incidence and valence of emotions in dreams and their relationship with waking life satisfaction, home and rapid eye movement (REM) sleep dreams were collected from 30 late adulthood and 28 young women who had filled out a life satisfaction scale. Four positive and 4 negative dream emotions were self-rated. Both groups reported more emotions, with greater intensity, in home dreams than in REM dreams, particularly the older group. Regardless of age, intensity of negative emotions was lower in laboratory dreams than in home dreams, but there was no difference for positive emotions. The older women's home dreams had fewer negative emotions, with lower intensity, than did the young women's. Life satisfaction did not differ between age groups and was not significantly related to dream emotions. These results reinforce the distinction between home and laboratory dreams and question the relation between dream emotions and life satisfaction.

Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic foot mat) during 4 consecutive reproductive cycles. Cage type and reproductive phase (estrous synchronization of doe rabbits, artificial insemination, partum, preweaning, and postweaning) were not statistically significant but tendentially affected FCCs (.05 < p < .10). Buck rabbits housed in SC showed higher FCCs than those housed in BC (27.42 pg g? 1 dried feces and 25.57 pg g? 1, respectively; SEM = 2.952). The highest FCC values were detected at artificial insemination (BC, 27.91 pg g? 1; SC, 30.45 pg g? 1; SEM = 3.520), highlighting that the phase of semen collection could be one of the most critical moments for buck rabbits, although further investigations are needed. These preliminary results suggest that measurement of FCC could be used as an indicator of chronic stress in buck rabbits. 相似文献

Lethal control is used extensively in New Zealand to control nonnative nonhuman mammals. Respondents were surveyed about 8 mammal groups considered pests and their attitudes toward their control and pest status. They also identified the most appropriate method of control for the 8 different mammals. Information was gathered from 3 groups of respondents: nonhuman animal protectionists, conservationists, and the general public. Conservationists routinely rated all animal groups as more severe pests than the general public or animal protectionists, who provided the lowest scores. Rats, stoats, brushtail possums, and rabbits were identified as the 4 most serious pests by all 3 groups. Conservationists were 5.7 and 2.6 times more likely to prefer a lethal method of control than protectionists and the general public, respectively. For all 3 groups an increase in pest score for a given animal saw a decline in importance placed upon the animal's welfare. This relationship was strong for the general public but weak for conservationists and animal protectionists. Understanding aspects of potentially opposing viewpoints may be invaluable in supporting the development of new welfare-focused control methods. 相似文献

This study was conducted within the context of the Animal Welfare Indicators (AWIN) project and the underlying scientific motivation for the development of the study was the scarcity of data regarding inter-observer reliability (IOR) of welfare indicators, particularly given the importance of reliability as a further step for developing on-farm welfare assessment protocols. The objective of this study is therefore to evaluate IOR of animal-based indicators (at group and individual-level) of the AWIN welfare assessment protocol (prototype) for dairy goats. In the design of the study, two pairs of observers, one in Portugal and another in Italy, visited 10 farms each and applied the AWIN prototype protocol. Farms in both countries were visited between January and March 2014, and all the observers received the same training before the farm visits were initiated. Data collected during farm visits, and analysed in this study, include group-level and individual-level observations. The results of our study allow us to conclude that most of the group-level indicators presented the highest IOR level (‘substantial’, 0.85 to 0.99) in both field studies, pointing to a usable set of animal-based welfare indicators that were therefore included in the first level of the final AWIN welfare assessment protocol for dairy goats. Inter-observer reliability of individual-level indicators was lower, but the majority of them still reached ‘fair to good’ (0.41 to 0.75) and ‘excellent’ (0.76 to 1) levels. In the paper we explore reasons for the differences found in IOR between the group and individual-level indicators, including how the number of individual-level indicators to be assessed on each animal and the restraining method may have affected the results. Furthermore, we discuss the differences found in the IOR of individual-level indicators in both countries: the Portuguese pair of observers reached a higher level of IOR, when compared with the Italian observers. We argue how the reasons behind these differences may stem from the restraining method applied, or the different background and experience of the observers. Finally, the discussion of the results emphasizes the importance of considering that reliability is not an absolute attribute of an indicator, but derives from an interaction between the indicators, the observers and the situation in which the assessment is taking place. This highlights the importance of further considering the indicators’ reliability while developing welfare assessment protocols. 相似文献
