Zoo elephant populations are in serious demographic peril. Advances in elephant management and care are expected to lead to improved reproductive success. The existing cohort of reproductively viable adult females is aging, however, and effective changes may not come fast enough to sustain the population over time. If so, importation of captive, semi‐domesticated, and wild elephants from range countries may be necessary for zoo programs to survive. Yet, due to the high profile elephants now have with animal rights activists, there may be increasing legal and political barriers to elephant importation. This makes it especially important that zoos become more proactive in addressing remaining weaknesses in elephant management and care and building the case for elephants in zoos. This article summarizes the key considerations for AZA‐accredited zoos that are contemplating future importations. These include ethical, legal, practical, public relations, and other considerations. The authors strongly recommend that zoos position themselves for possible future importations immediately instead of waiting until the last minute. It is equally critical that zoos recognize their existing vulnerabilities and attempt to address them proactively; only then, can they take control of their own fate and reduce the potential for later regret.

Poor reproductive success compromises the long-term viability of captive Asian elephant populations. A questionnaire was designed to assess the importance of reproductive behavior and husbandry factors on breeding success. This was circulated to a number of institutions, zoos, and circuses in Asia, Europe, and North America, all of which kept Asian elephants. The aims were to compare Asian elephant breeding success in different institutions, establish possible causes for any differences, and make recommendations for improving the welfare and breeding success of the animals. The results showed that breeding success in most of the zoos was notably lower and the percentages of stillbirths and infant mortality were relatively higher when compared with those of the institutions in Asia. Female elephants in zoos appeared to reach sexual maturity and reproduce earlier than those in the Asian establishments. However, zoo elephants produced fewer young per female. The different facilities and husbandry methods used are described. Recommendations are made for both short- and long-term changes that could be used to modify existing practices to improve the welfare and breeding success of captive Asian elephants.

ABSTRACTWe surveyed the attitudes of people toward captive elephants in australia, where importation into zoos has been controversial recently, compared with India, where elephants are indigenous. Both australian (AR, n = 101) and Indian (IR, n = 101) respondents rated conservation as the most important reason for the role of zoos and sanctuaries. Australian respondents were more concerned about the husbandry conditions for keeping wild animals in zoos and sanctuaries than Indian respondents (p = 0.02). This concern for captive animals increased with the higher educational level of the respondents. Female australian respondents were more concerned about the practice of keeping elephants in captivity than australian men. More australian respondents were prepared to pay extra to visit a zoo with elephants (AR 42.6%, IR 7.9%, p < 0.001). Indian respondents believed more than their australian counterparts that it was important for any zoo to display elephants, and wanted to interact with elephants by feeding, touching, and riding on them. While australian respondents? perceptions of captive elephants acknowledged their scientific value, Indian respondents viewed elephants primarily of religious, cultural, and historical significance. We conclude that australians and Indians have different requirements for keeping elephants in zoos, which should inform zoo directors about the best way to present them to the public. 相似文献

In the discussion about zoo elephant husbandry, the report of Clubb et al. (2008, Science 322: 1649) that zoo elephants had a “compromised survivorship” compared to certain non-zoo populations is a grave argument, and was possibly one of the triggers of a large variety of investigations into zoo elephant welfare, and changes in zoo elephant management. A side observation of that report was that whereas survivorship in African elephants (Loxodonta africana) improved since 1960, this was not the case in Asian elephants (Elephas maximus). We used historical data (based on the Species360 database) to revisit this aspect, including recent developments since 2008. Assessing the North American and European populations from 1910 until today, there were significant improvements of adult (≥10 years) survivorship in both species. For the period from 1960 until today, survivorship improvement was significant for African elephants and close to a significant improvement in Asian elephants; Asian elephants generally had a higher survivorship than Africans. Juvenile (<10 years) survivorship did not change significantly since 1960 and was higher in African elephants, most likely due to the effect of elephant herpes virus on Asian elephants. Current zoo elephant survivorship is higher than some, and lower than some other non-zoo populations. We discuss that in our view, the shape of the survivorship curve, and its change over time, are more relevant than comparisons with specific populations. Zoo elephant survivorship should be monitored continuously, and the expectation of a continuous trend towards improvement should be met. 相似文献

In 1987 the National Zoological Park inaugurated a Zoo Biology training program for developing country zoos, particularly those in the tropics where the threats to biological diversity are greatest. The program last 2 to 4 weeks, is targeted to mid-level zoo managers, and aspires to improve the care and management of wildlife in zoos through in situ training. A host zoo in the foreign country is responsible for selecting and inviting trainees from other zoos in the country or region. Training activities include daily lectures, demonstrations, quizzes, problem solving exercises, and class projects. In addition, the class participates in creating an animal inventory for the host zoo, and endemic species are identified for studbook compilation and captive propagation projects. Most mid-level zoo managers in tropical developing countries are college-educated men in their thirties, and have on average less than 10 years of zoo experience. We evaluate our program, and discuss the problems confronting tropical zoos in the developing world. Finally, we suggest ways that zoos in developed countries can influence tropical conservation through training and education. 相似文献

With increased scrutiny surrounding the welfare of elephants in zoological institutions, it is important to have empirical evidence on their current welfare status. If elephants are not receiving adequate exercise, it could lead to obesity, which can lead to many issues including acyclicity and potentially heart disease. The goal of the current study was to compare the walking rates of elephants in the wild versus elephants in zoos to determine if elephants are walking similar distances relative to their wild counterparts. Eleven wild elephants throughout different habitats and locations in Botswana were compared to 8 elephants at the San Diego Zoo Safari Park. Direct comparisons revealed no significant difference in average walking rates of zoo elephants when compared with wild elephants. These results suggest that elephants at the San Diego Zoo Safari Park walk similar rates to those of wild elephants and may be meeting their exercise needs. 相似文献

Caring for all aspects of zoo elephants’ well-being is considered a major challenge. Providing an appropriate flooring substrate to facilitate lying rest presents a meaningful part of a holistic management concept. Investigating the impact of a new sand flooring on the nocturnal resting behavior of a breeding group of seven African elephants living at one zoo revealed more total lying rest, longer bouts of lying rest and a reduced side preference in the adult females. With an average total daily lying rest of about 1.5–2.0 hrs, the investigated zoo elephants expressed longer lying rest compared to recently reported data from free-ranging individuals in Botswana. In addition, the presence of nursing calves in the observed elephant group seemed to impact the resting pattern of all group members, with around 60% of all lying bouts being discontinued after interruption by the youngsters. With respect to observed nursing during leaning rest, we encourage the installation of appropriate horizontal structures in breeding facilities to support leaning rest behavior of their female elephants. In doing so, zoos may improve rest quality of nursing females, and, in general, the welfare aspect of sleep for their elephants. 相似文献

Media characterizations of zoo and aquarium animal deaths were randomly monitored on the internet for a 20‐month period (September 2003–May 2005). Based on 148 samples collected, it was possible to classify articles into one of four categories, which were operationally defined: 1) dispassionate observers; 2) accusers; 3) sympathizers; and 4) balancers. In addition, with the notable exception of seven cases, all of the articles examined focused on large, charismatic mammals, such as gorillas, dolphins, lions, and elephants. Although a majority of the articles examined (70.4%) were either dispassionate and objective or sympathetic, nearly a third (29.6%) were either accusatory or attempted to balance the accusatory statements of animal rights activists with sympathetic statements from zoo professionals. Recommendations are offered for how zoos should deal with the increasing media and public interest in zoo animal deaths, including: 1) a greater commitment to studying the reasons for mortality in a wide variety of species; and 2) an increased investment in record keeping and analysis, which should allow zoos to calculate average life spans in animal populations and to monitor and assess the risk of certain lethal diseases on a real‐time basis. Comparisons are drawn between zoo veterinary practices and human medicine, which are both inexact sciences. Suggestions are made for how the public and key decision‐makers can distinguish between media reports on zoo animal deaths that are legitimate cause for concern vs. those that are sensationalist and meant to generate controversy and sell papers. A greater focus on the science of zoo animal death is necessary for accredited zoos to maintain the public's confidence in their animal care practices.

While recent work has assessed how environmental and managerial changes influence elephant welfare across multiple zoos, few studies have addressed the effects of management changes within a single institution. In this paper, we examine how management changes related to social structure and diet affect the behavior of a group of zoo elephants over a 23‐month period while also considering underlying factors, such as time of day, hormonal cycle, and individual differences. We recorded individual behaviors using 2‐min scan samples during 60‐min sessions. We analyzed behavioral changes across several study variables using generalized linear mixed models. We found that increasing browse can improve opportunities for foraging throughout the day but may not be sufficient to reduce repetitive behaviors. We observed that increasing group size and integration of bulls with cows can lead to increased social interaction in African elephants. Our results highlight the importance of using multiple management alterations to address elephant welfare, and considering environmental factors, when making management decisions. 相似文献

As recorded in domestic nonhuman animals, regular interactions between animals in zoos and keepers and the resulting relationship formed (human–animal relationship [HAR]) are likely to influence the animals' behaviors with associated welfare consequences. HAR formation requires that zoo animals distinguish between familiar and unfamiliar people. This ability was tested by comparing zoo animal behavioral responses to familiar (routine) keepers and unfamiliar keepers (participants in the “Keeper for the Day” program). Study subjects included 1 African elephant (Loxodonta Africana), 3 Rothschild's giraffes (Giraffa camelopardalis rothschildi), 2 Brazilian tapir (Tapirus terrestris), and 2 slender-tailed meerkats (Suricata suricatta). Different behavior was evident and observed as decreased avoidance behavior toward familiar keepers (t7 = 6.00, p < .001). This finding suggests the zoo animals have a lower level of fear toward familiar keepers. Keeper familiarity did not significantly affect any other behavioral measure. This finding suggests that in the current study, unfamiliar keeper presence did not appear to have detrimental effects. Furthermore, unfamiliar keeper–animal interactions could provide an increased number of positive human–animal interactions and potentially enhance animal welfare. 相似文献

ABSTRACTTo some, zoos are prisons exploiting animals. In reality zoos range from bad to better. I make this distinction: A bad zoo makes animals work for it; a good zoo works for animals. Good zoos do effective conservation work and continually strive to improve exhibits, relevance to conservation, and inspiring public engagement for wildlife. Many zoos have improved enormously; the better ones being crucial in saving species that would have otherwise gone extinct. Nonetheless, for some people the mere word “zoo” carries impressions of old zoos, bad zoos, circuses, and theme-park shows that many find distasteful. Good zoos know they must innovate forward. As society grows increasingly estranged from nature and continues driving broad declines of wildlife, wild lands, and natural systems, the goal of zoos and every organization concerned with animal welfare should not be to separate humans from other animals, but to entangle all humans in nonhuman lives. Zoos of the next decades must become the first stage in bringing young people into life-long, engaged caring about animals. They could carry on that mission in their communities, in schools, in wild lands, as well as inside their gates. Without a strong public constituency, wild animals will not withstand continued human proliferation. Zoos and aquariums must innovate toward being a crucial force abetting the continued existence of wildness on Earth. Zoos of the future must become uplifting places of respect, rescue, enhancement, conservation, and public engagement. 相似文献

ABSTRACTNonhuman animal welfare science is the scientific study of the welfare state of animals that attempts to make inferences about how animals feel from their behavior, endocrine function, and/or signs of physical health. These welfare measurements are applicable within zoos yet inherently more complex than in farms and laboratories. This complexity is due to the vast number of species housed, lack of fundamental biological information, and relatively lower sample sizes and levels of experimental control. This article summarizes the invited presentations on the topic of “Advances in Applied Animal Welfare Science,” given at the Fourth Global Animal Welfare Congress held jointly by the Detroit Zoological Society and the World Association of Zoos and Aquariums in 2017. The article focuses on current trends in research on zoo animal welfare under the following themes: (a) human–animal interactions and relationships, (b) anticipatory behavior, (c) cognitive enrichment, (d) behavioral biology, and (e) reproductive and population management. It highlights areas in which further advancements in zoo animal welfare science are needed and the challenges that may be faced in doing so. 相似文献

The concept that animals have personalities is gaining traction in the scientific community and is well established in zoos and aquariums. Applying knowledge of animal personalities has occurred more slowly and is most often only considered informally. However, animal personalities are likely to affect the welfare animals experience in captivity and thus should be of primary concern to zoo managers. In addition, animal personality likely affects the outcomes of zoo guest experiences and potentially guests' conservation‐related behavior. With over 1,000,000 animals in the care of zoos internationally and hundreds of millions of visitors annually, it would be prudent and beneficial to maximize our use of animal personality data in zoos to effect positive conservation outcomes. Understanding how to broaden population planning techniques to include measures of animal personality and the important outcomes of welfare and education value is of prime importance to the zoo industry. In order to succeed, it is necessary to employ techniques that reliably assess animal personalities and provide measures that can easily be used in population planning models. We discuss the outcomes of recent workshops designed to determine the best techniques for measuring animal personalities in the zoo setting with the goal of incorporating personality into population planning.

ABSTRACTAnimal welfare concerns have plagued the professional zoo and aquarium field for decades. Societal differences remain concerning the well-being of animals, but it appears a shift is emerging. Scientific studies of animal welfare have dramatically increased, establishing that many previous concerns were not misguided public empathy or anthropomorphism. As a result, both zoo and aquarium animal welfare policy and science are now at the center of attention within the world’s professional zoos and aquariums. It is now possible to view a future that embraces the well-being of individual captive exotic animals, as well as that of their species, and one in which professional zoos and aquariums are dedicated equally to advancing both. Though the ethics of keeping exotic animals and animals from the wild in captivity are still a contentious subject both outside and even within the profession, this study argues. We argue that this path forward will substantially improve most zoo and aquarium animals' welfare and could significantly reduce societal concerns. If animal welfare science and policy are strongly rooted in compassion and embedded in robust accreditation systems, the basic zoo/aquarium paradigm will move toward a more thoughtful approach to the interface between visitors and animals. It starts with a fundamental commitment to the welfare of individual animals. 相似文献

The management of socially complex species in captivity is challenging. Research on their social behavior improves our understanding of interactions in captive animals and captive‐group management. We conducted a detailed analysis of social relationships shown by the orcas kept at Loro Parque zoo and their tendency to reconcile after aggressive episodes. Affiliative interactions were the most frequent social activities compared to agonistic or sexual interactions. Within affiliative behaviors, we documented the pattern “gentle tongue bite”, where an animal touches the other's tongue with his teeth but does not bite it. Affiliative interactions between a specific pair of orcas occurred significantly more often than expected by chance, and together with low levels of agonistic interactions, indicated particular affinity between some individuals. The most frequently observed low‐level agonistic relationship was that of the two older males (Tekoa–Keto); however, they also showed frequent sexual and affiliative interactions. Sexual‐like behaviors (pursuit, mount, and penis between males) were found in both sexes. Finally, the observed corrected conciliatory tendency (31.57%) was within the range described for other primate and cetacean species. This study provides a systematic way to assess social interactions as well as conflict management strategies in cetaceans housed in zoos and zoo‐like facilities and may help to improve animal welfare and management of animals in controlled environments. 相似文献

The artificial living conditions of captive animals present numerous challenges for animal caretakers. In this study I explored abnormal behaviors in certain caged animals at the Kuala Lumpur Zoo. Findings obtained from observations of animals and interviews of the zoo staff are followed by recommendations: including the development of standards and manuals, licensing of zoos and animals, and increased budgets from governments or alternative sources. Such interventions should bring considerable improvements in animal welfare at the zoos in the region. 相似文献

Modern zoos strive to improve standards of animal management, husbandry and welfare of their animals as part of a continual evaluation process. Elephants (Elephantidae) have received particular attention in recent years due to the challenge of providing environments which promote natural behavior and opportunities for social interaction. A number of measures have been proposed to measure wellbeing, with sleep quality increasingly being used. Sleep is a vital aspect of life for cell replenishment as well as optimal development of young. Sleep deprivation can lead to immunosuppression and illness; therefore animal managers have a responsibility to ensure they reduce the potential for disturbance through noise, light, or other environmental factors. The social environment also plays an essential role in wellbeing, particularly for species that live in multi-generational family units. In this study the nocturnal behavior of a multi-generational captive herd was observed to determine impacts of husbandry changes on sleep duration and bout length (measured as recumbent rest). As expected, average total duration of sleep was higher in younger elephants and rates were comparable to those reported in other studies of Asian elephants. Overnight access to an outdoor paddock in warmer weather increased overall average bout length of sleep in the herd. Average total duration of sleep also increased for the herd following the movement of an unrelated adult female who had previously shown weak bonds with other herd members. This indicates that social compatibility is a vital component of elephant welfare, impacting not only behavioral interactions but sleep quality and duration. 相似文献

Although the accredited institutions of the Association of Zoos and Aquariums have all committed to enhancing the welfare of nonhuman animals, acceptable standards and best practices are still under debate. Currently, experts from zoos and the field hold widely divergent opinions about exhibition and management standards for elephants. Standards and practices for managing nonhuman primates provide a model for other nonhuman creatures exhibited in zoos and aquariums. Examining the key issues for primates demonstrates the value of applying scientific data before promulgating standards. The field of applied behavior analysis provides a wealth of information to frame the debate. Animal behaviorists have contributed to an emerging science of animal welfare, which may provide a foundation for empirical zoo management, standards, and practices. 相似文献
