The design of zoo and aquarium exhibits has a strong influence on visitor behavior in exhibit enclosures. Furthermore, zoo exhibits with underwater viewing draw large crowds. The intent of this study was to formulate significant design criteria, through post-occupancy evaluation, to be used for the design of successful underwater exhibits in zoos. This study was conducted to reveal factors significantly influencing viewing time and visitor behavior in zoo exhibits with underwater viewing. At four zoo facilities, 331 visitor groups were observed and asked to participate in a short survey at six zoo exhibits. Chi-square analysis and analysis of variance (ANOVA) were used to evaluate observation and survey results. The size of the underwater viewing window, animal size, animal aquatic activity, presence of infant animals, visitor group type and crowding levels had a significant impact on visitor behavior. Recommendations for the future design of underwater zoo exhibits are discussed.

Zoological gardens, or zoos, keep and display wild animals, mainly for the purposes of education, conservation and biological research. However, it is evident that a significant component of zoos is the vast number of people who visit them, since without the support of visitors, zoos would not be financially viable and would cease to exist. This research investigates the behaviours of these visitors and develops an understanding of their awareness relating to what they see and do while they are in the zoo, along with their motivations for visiting. The study focuses on two major metropolitan zoos in Australia: Adelaide (in South Australia) and Taronga (in Sydney, New South Wales). A brief historical account contextualises changes, raising awareness of the significance of visitors to the livelihood of zoos. More and more zoos are integrating into their management routines different programmes that relate to the care and welfare of the animals. Despite recent growth in scientific attention, which has focused on human-animal relationships, little research has been conducted relating to the human visitor in the zoo. To date, decisions made by administrators have been based upon assumptions of the visitors’ understanding of the work of zoos rather than on actual quantitative findings. This empirical research is significant in that it uses both quantitative and qualitative methods to appraise factual data and information. The data from unobtrusive tracking observations at different exhibits, combined with the results of questionnaire surveys, are used to explore and assess the perceptions of visitors. In developing a demographic profile of the people who visit zoos, this work considers the motivations and the frequency of visitors. Various factors that influence the viewing patterns of visitors are explored to assess the popularity of exhibits, and the perceptions of visitors relating to animals and enclosures are investigated, to assess the diverse levels of satisfaction. Case studies explore the perceptions and understandings of visitors towards the use of enrichment items, the use of signs and labels, and a hypothetical approach to the feeding of carnivores in zoos. The results are important in that they contribute essential knowledge that describes the perceptions of a wide range of people who visit zoos, along with their expectations, since it is crucial for these institutions to maintain their popularity with the public.

An increased understanding of species-specific behavioral needs has lead zoos to focus on providing more naturalistic and stimulating environments. Scientific assessments of how changes in habitat affect animal behavior are necessary in improving overall animal welfare. This study examined the move of three orangutans housed at the Oregon Zoo into a new and innovative exhibit. Post-occupancy evaluation (POE), which offers systematic information regarding the success or failure of the built environment (Maple & Finlay, 1987), was utilized to effectively evaluate the results of the move. The collection of behavioral data and adrenal activity monitoring through collection of non-invasive saliva, urine and hair provided a comprehensive methodology for comparing changes in behavior and physiological functioning. Behavioral results showed that following the move to the new enclosure animals spent less time inactive, more time at higher elevations and utilized exhibit structures at a greater frequency. Hormonal results suggest that detection of cortisol in orangutan hair could be a useful tool for monitoring chronic stress.

Five captive Bornean orangutans (Pongo pygmaeus) were observed in order to better understand their spatial selection, behavior, and interaction with their environment and each other. A newly introduced adult male's interactions with a female group containing two adults, one adolescent, and one juvenile, was documented. Visual observations were performed to document individual behaviors, along with any interactions with silvery langur monkeys, public crowd levels, temperature, and enrichment props. Methods included 15 observation periods, 0.5-3 hours in length each, during which behaviors were verbally and visually confirmed using a HD video camera. Spatial locations of each individual were recorded every three minutes during each observation period. The orangutan enclosure was measured and mapped using terrestrial laser scanning (TLS), and observed behaviors and spatial locations were georeferenced to the resulting 3D model depicting the exhibit. Results were summarized as time-activity budgets and were geo-visualized using 3D plots and density maps. This research demonstrated how the application of spatiotemporal and behavioral analysis coupled with TLS and three-dimensional modelling can be used to better study captive primates. These types of studies are important as zoos increasingly become home to great ape species.

African savanna elephants (Loxodonta africana) and Asian elephants (Elephas maximus) are a focus of welfare research in zoos due to their high intelligence, complex social structure, and sheer size. Due to these challenges, some argue that zoos are inherently incapable of providing appropriate care for elephants, while others believe that zoos can fulfill the needs of these species with improved husbandry. There is a general consensus from both within and outside of zoos, however, that zoos must improve their elephant programs or cease exhibiting these animals altogether. Now more than ever, applied research on zoo elephant welfare is needed to provide context for this debate. Researchers are interested in how far zoo elephants walk due to the potential health and welfare benefits of walking in these highly mobile species. Zoo researchers recently adopted GPS technology to study elephant walking, and preliminary evidence suggests that African elephants in large zoo exhibits walk distances that correspond with wild elephants under non-extreme conditions. However, data are limited from Asian elephants and from elephants in more typically-sized exhibits. In Chapter Two, I discuss important methodological considerations of utilizing GPS in a zoo environment, including an introduction to the technology, sources of error and mitigation, methods to improve GPS performance, and possible effects of GPS device attachment on animal behavior. This review shows GPS performance is adequate for tracking zoo elephant walking when proper methodological techniques are applied, and should serve as a useful reference for zoo researchers considering using GPS. In Chapter Three, I used GPS anklets to measure outdoor daily walking distance in 56 adult female African (n = 33) and Asian (n = 23) elephants housed in 30 zoos. I collected 259 days of data and found that elephants walked an average of 5.34 km/day with no significant difference between species. Multivariate regression models predicted that elephants with more dynamic feeding regimens (more diverse feeding types and frequencies; unscheduled feeding times) will walk more. Distance walked was also predicted to be higher in elephants that spend time in a greater number of different social groups. Distance walked was predicted to decline with age. Finally, I found a significant negative correlation between distance walked and nighttime space experience. The results of the analysis suggest that zoos that want to increase walking in their elephants need not rely solely on larger exhibits, but can increase walking by adding quality and complexity to exhibits. However, my results failed to establish a definitive link between walking distance and other validated measures of elephant welfare. Thus, the direct health and welfare benefits of walking in zoo elephants remain unresolved. Resting behaviors are an essential component of animal welfare, but have received little attention in zoological research. In Chapter Four, I used accelerometers in anklets to complete the first large-scale multi-species investigation of zoo elephant recumbence. I collected 344 days of data from 72 adult female African (n = 44) and Asian (n = 28) elephants at 40 zoos. I found that African elephants are recumbent an average of 2.14 hours/day, which is significantly less than Asian elephants at 3.22 hours/day. Multivariate regression models predicted that African elephant recumbence increases when they experience more space at night, and Asian elephant recumbence increases when they spend time housed alone. Both species showed a similar response to substrate, such that African elephants spending time on all-hard substrates are predicted to be recumbent less, while Asian elephants spending time on all-soft substrates are predicted to be recumbent more. The discovery that occasional non-recumbence is a common behavior in zoo elephants also introduces a new area of research that may have important animal welfare consequences. Finally, this study established that zoos should continue their efforts to replace hard substrate with soft substrate in order to provide zoo elephants with environments that facilitate recumbence. Overall, this work assessed walking and recumbence in zoo elephants, which will allow zoos to gauge the prevalence of these behaviors in their elephants as compared to the sub-population studied here. A variety of factors that are associated with these behaviors were also identified. With this information, zoos can prioritize modifications to their facilities and animal management programs to create an environment that encourages zoo elephants to express walking and recumbence behavior, should they choose to do so. This work is one component of the Elephant Welfare Project, the largest zoo animal welfare project ever undertaken, and is unprecedented in both scope and scale. The project was funded by the Institute of Museum and Library Services (IMLS), an independent, U.S., federal, grant-making agency that supports libraries, museums, and zoos. At the time of this writing, the first manuscripts from this project are being submitted to academic journals. These papers will describe the prevalence and distribution of a variety of elephant behaviors and welfare indicators, serve as a benchmark for future elephant welfare studies, and aid in decision making with regard to best practices in elephant management.

The purpose of this thesis project is to develop a set of interactive digital solutions designed to enhance the interest and knowledge intake of visitors at Skånes Djurpark (Zoo of Scania) in Höör. The project was carried out in collaboration with Skånes Djurpark and representatives from its visitors. Our thesis is based on academic works in the fields of interaction design, exhibit design and contextual learning. Ethnographical field studies have been conducted at Skånes Djurpark with additional field studies at Tropikariet in Helsingborg, Copenhagen Zoo and Regionmuseet Kristianstad. Existing information signs in Skånes Djurpark are primarily image- and textbased, forcing visitors to divert their attention from the different species of Nordic animals that inhabit the zoological park. Our proposed set of designs include interactive signage solutions using audiomedia, which allows visitors to learn by listening to stories while experiencing and physically looking at living animals.

The present study, in contrast with previous work that has isolated one or two important factors influencing the status of the zoo, considered the three important zoo reference groups--animals, visitors, and staff members--and their interrelationships within the zoo environment. Two approaches were used to investigate the system of interactions within the zoo. First, an in-depth examination of a new set of naturalistic exhibits was performed. Second, a comparison of two of these naturalistic exhibits with two older, sterile exhibits which housed the same species at the same zoo was made. Multiple methods were used in the present study and included behavior mapping of visitors, staff, and animals, timing of visitor stays at exhibits, tracking of visitors through the exhibits, a visitor questionnaire, and interviews with staff members. One major finding was the lack of correspondence among the major groups as to the acceptability of exhibits. For example, one exhibit which was considered beneficial to the enclosed animals and was well utilized and positively evaluated by visitors presented staff members with great difficulties in animal containment and exhibit maintenance. Comparisons of naturalistic enclosures and sterile cement enclosures housing the same species revealed no consistent, clear-cut differences in animal and visitor behavior, however, attitudinal differences were found for staff members and visitors. Visitors and staff members preferred the naturalistic exhibits and perceived them as more beneficial to animals and visitors. These findings were discussed in terms of theoretical and applied issues relevant to zoo design and management and to research in zoos.

By studying how captive animals use outdoor space, we can determine which areas fulfill their biological and behavioral needs to improve enclosure design for animal welfare and visitor experience. The aim of the study was to determine the differential use of outdoor space in a mixed exhibit of captive ring-tailed lemurs (Lemur catta) and red ruffed lemurs (Varecia rubra), and to assess both the effect of adding environmental enrichment and possible visitor and meteorological effects on the lemurs’ use of space and behavior. For one month, five-minute interval scan sampling was used to record lemur location and behavior, as well as the meteorological conditions and presence of zoo visitors in the lemurs’ outdoor enclosure. That baseline was followed by four alternating two-week periods of food or structural enrichment, both with and without visitors. Enrichment increased the lemurs’ use of the enriched sectors, decreased resting, and increased locomotion. Structural enrichment increased their exploratory behaviors and stimulated arboreal locomotion. Both species preferred sunny and warm conditions for sunbathing and resting, while moving more around the enclosure in cooler and cloudier weather. The visitor effect on the lemurs’ use of space was weaker than the effects of enrichment and meteorological conditions. The availability of areas to hide and possible habituation to humans may have played a role in the reduced visitor effect. The results of the study showed inter-specific differences in the lemurs’ use of space and behavior and a complex combined effect of enrichment, visitor presence and meteorological conditions.

Zoos and aquariums are uniquely placed to promote pro-environmental messages to a broad sector of the population. Their ability to connect people with wildlife may facilitate meaningful behaviour change in support of conservation efforts. Many modern zoos have evolved their educational strategies to incorporate social science and psychology to enhance the effectiveness of their visitor conservation education programs. However, very little has been published on the role of zoo design in contributing to the effective delivery of conservation or pro-environmental messages aimed at affecting behaviour change in zoo visitors. This novel study seeks to understand whether zoo exhibit design can impact the efficacy of these zoo-based campaigns. Visitor surveys and observations at two Sumatran tiger exhibits in New South Wales, Australia (Taronga Zoo and Taronga Western Plains Zoo), were used to understand the impact of visiting these exhibits on visitors' perceived behavioural control, attitudes, connections and behavioural intention regarding tiger conservation. The results of this study show that these factors were positively impacted by visiting a tiger exhibit. Perceived behavioural control is the most significant contributor to intention to undertake behaviours that help protect in the wild. There is some relationship between engagement with zoo exhibits (particularly interactive elements) and visitor perceived behavioural control, attitudes related to tiger conservation, and sense of connection to the natural world. Tiger visibility was found to be the most significant exhibit engagement factor in contributing to increasing a sense of connection to tigers. This thesis demonstrates that modern, immersive zoo exhibit design can be an effective part of the 'behaviour-change toolkit' available to modern zoos in the pursuit of meaningful pro-environmental behaviour outcomes in the zoo-going public, and makes explicit suggestions for zoos on how to maximise the success of their behaviour change campaigns.

Amid rapidly increasing anthropogenically caused wildlife extinctions, zoos are often expected to embrace the role of proactive conservation organizations. Many are leading the way through innovations in the development of engaging visitor experiences. This paper evaluates the effectiveness of the new and cutting-edge immersive interpretation within the TigerTrek Exhibit at Taronga Zoo (Sydney, Australia), for its ability to influence visitors to engage in pro-conservation behaviors related to certified sustainable palm oil advocacy and consumerism. Survey data were collected from zoo visitors prior to entering the Sumatran Tiger Trek exhibit (n = 514), upon exiting the exhibit (n = 509), and by email at six-week (n = 106) and six-month (n = 18) intervals post-visit to investigate the immediate and long-term impacts of the exhibit on visitors’ pro-conservation behavioral intentions and actual behaviors. Results indicate an increase in post-visit respondents’ levels of awareness (χ2 = 65.26 (1), p < .001), motivation (t = -6.976 (1029), p < .000) and behavior intentions (t = -5.256 (1042), p < .000), however, post-visit respondents also reported increased levels of concern that all palm oil is grown unsustainably (χ2 = 9.09 (1), p < .01), which runs contrary to interpretive messaging. Follow up surveys revealed after both six-weeks and six-months post-visit; 29.2% of respondents purchased a product because it contained Certified Sustainable Palm Oil, however, 50% of six-week respondents had actively avoided buying a product because it contained palm oil. By understanding how visitors perceive the interpretive messaging within an exhibit and appreciating the types of conservation behaviors visitors are willing and able to engage in, zoos can more effectively achieve their conservation campaign goals.
