Dolphin shows and interaction programs: benefits for conservation education?

Ambassador Animals Do Not Have a Clear Effect on Visitor Conservation Knowledge and Attitudes Toward Exotic Pets at a Zoo Exhibit

There is relatively little work examining visitor outcomes of ambassador animal programs, such as whether these programs are educationally effective or unintentionally promote exotic pet ownership. We designed a two-way factorial experiment to test whether ambassador animals enhanced or detracted from the educational outcomes of a zoo exhibit. We surveyed 312 visitors at the Oakland Zoo at a static exhibit focused on the illegal wildlife trade. Participants were surveyed either before or after visiting the exhibit, with or without a trainer presenting either an ambassador ball python (Python regius) or yellow-naped Amazon parrot (Amazona auropalliata). The survey assessed attitudes toward conservation, knowledge of conservation behavior, and the suitability of various species, including the ambassador species, as pets. We used an ANOVA to examine 299 complete surveys for differences between experimental groups' mean responses. There were no significant differences in conservation attitudes. Subjects demonstrated more knowledge of conservation behavior after leaving the exhibit, regardless of whether or not an animal was present. While the exhibit reduced favorable attitudes toward parrots as pets, ambassador animal presence neither positively nor negatively impacted on this effect. Participants who viewed a python were more likely to indicate that they viewed a python as a good pet. However, the sample expressed overall negative attitudes toward exotic pet ownership. This study suggests that ambassadors neither enhanced learning nor unintentionally promoted exotic pets. Further research is needed to understand the role of interpretive messaging when using ambassadors in an educational context.

A meta-analysis of the effect of visiting zoos and aquariums on visitors' conservation knowledge, beliefs, and behavior

Zoos and aquariums are well placed to connect visitors with the issues facing biodiversity globally and many deliver interventions that seek to influence visitors' beliefs and behaviors with respect to conservation. However, despite primary studies evaluating the effect of such interventions, the overall effect of engaging with zoos and the factors that influence this effect remain unclear. We conducted a systematic review to investigate the effect of zoo-led interventions on knowledge, beliefs (attitudes, intentions, self-efficacy, and social norms), and behavior among zoo visitors. These outcomes were identified using the Theory of Planned Behavior as a theoretical lens. We identified and described the nature of zoo-led interventions in 56 studies and used the behavior change technique (BCT) taxonomy to identify 6 specific BCTs used in interventions to date. Multilevel meta-analyses revealed a small to medium positive effect of engaging with zoo-led interventions on outcomes (d+  = 0.40, 95% confidence interval = 0.28-0.51). Specifically, visitors were more knowledgeable about conservation issues, held more favorable attitudes toward conservation, and reported being more likely to act for the benefit of biodiversity. No evidence of publication bias was present. Effect sizes were, however, heterogeneous and subgroup analyses revealed that the nature of the intervention or type of outcome did not explain this variance. Larger effects were, however, found in studies conducted at a single institution relative to research at multiple institutions and studies that used within-participant designs relative to between-participant designs. Taken together, these findings demonstrate how behavior change frameworks can be used to describe zoo-led interventions and supports the assertion that zoos and aquariums can promote changes in beliefs and behaviors that may help protect biodiversity.

Animals as performers or exhibits: A study of their relevance to Portuguese, Spanish, and Greek pre-service teachers

This study involves Portuguese, Spanish and Greek pre-service primary teachers (n = 210) and pre-service kindergarten teachers (n = 195) and identifies through a questionnaire a) their personal opinions and b) perception of the didactic value of eight performances with live animals. The results were compared by course among countries and between courses in the same country. Globally, the pre-service teachers neither showed a great personal interest, nor recognized great didactic relevance in these shows. Pre-kindergarten teachers from Portugal and Spain tend to value them more positively as a way to bring children closer to animals. Shows with aquatic mammals received the greatest appreciation in both dimensions, especially in the Greek sample; birds of prey shows were valued more by the Iberian participants. Violent shows, such as fighting animals and bullfighting, were very negatively viewed. Shows with pets and birds of prey were viewed frequently as more detrimental to animals than they are. The results show that a better understanding of the impact of each show on animals is needed, if pre-service teachers are to make informed decisions in their professional future.

The Role of Zoos and Aquariums in a Changing World

Zoos and aquariums have evolved significantly. From their origins as enclosures for the mere entertainment of the public, these institutions have undertaken new functions responding to the biodiversity crisis and social demands. Modern zoos and aquariums have the opportunity to educate people, contribute to species conservation, and produce animal-related research. However, there is increasing criticism toward the outcomes of their actions and the holding of species in their facilities. This review offers an integrated analysis of the state of knowledge about the role that zoos and aquariums play today. It describes their performance regarding their conservation, education, and research functions, highlighting general patterns and offering future perspectives. It identifies some challenges common to all these institutions, concluding that the way they keep up with the ever-growing social and environmental expectations will be decisive hereafter.

Learning outcomes measured in zoo and aquarium conservation education

Communicating the topic of conservation to the public and encouraging proenvironmental behaviors can mitigate loss of biodiversity. Thus, the evaluation of educational efforts is important to ascertain the educational effects and provide high-quality conservation education. The learning outcomes of conservation education are diverse (e.g., attitudes, knowledge, and behavior). Considering the specific characteristics of these different outcomes and the factors that influence them is crucial to delivering successful conservation education. We reviewed 29 peer-reviewed articles published in English from January 2011 to April 2020 on empirical studies of learning outcomes of on-site conservation education in zoos and aquaria, institutions that seek to educate the public about conservation. We examined the range of learning outcomes, their definitions, and factors that influenced them. Cognitive outcomes were most frequently investigated (37%) in comparison with other outcomes (e.g., affective outcomes, 31%). The articles did not use explicit definitions for learning outcomes, and implicit or explorative definitions provided were inconsistent. Outcomes were influenced by various factors (e.g., prior experiences, staff interaction, animal behavior). Our results suggest the agenda of conservation education research should be broadened by examining all learning outcomes relevant to behavior change. Educational and behavior change theories should be used as a background for conservation education research to ensure clear and consistent definitions, derive appropriate instruments to measure learning outcomes, and relate learning outcomes to influencing factors. We recommend conservation education researchers and practitioners to treat conservation education holistically and acknowledge its learning outcomes' full complexity.

Effects of New Seal Introductions on Conspecific and Visitor Activity

Simple Summary

Modern zoos and aquariums are defined by several goals, which include improving the welfare of their animals, conservation efforts, public education, research, and visitor enjoyment. Animal-Visitor Interactions (AVIs) are a means to study the outcomes of some of these goals. These outcomes can be measured in terms of visitor effects (the effects of the visitors on the exhibited animals) and visitor experiences (the effects of the animals and the institution itself on the visitors). Additionally, new animal introductions have been examined for their effects on animals, but little has been done to measure the introduction visitor experience. The purpose of this study was to observe the effects of new animal introductions at two exhibits on both animal and visitor activity. Changes in existing animals’ behaviors and visitor crowd size and length of stay were measured before and after new animal introductions. The introduction had neutral to positive impacts on both variables, suggesting potential benefits on AVIs based on new animal introductions. Such studies could help establish best practices for new animal introductions and ways to promote positive AVIs within a zoo/aquarium setting.

Abstract

Modern zoos and aquariums are defined by several primary goals, which include improving the welfare of their animals, public education, and inspiring visitors to develop an interest in conservation. Animal-Visitor Interactions (AVIs) (i.e., the impact of captive animals and visitors on each other) are a primary means to study these goals. The introduction of new animals into two seal exhibits—the harbor and northern fur seals—at the Seattle Aquarium presented a valuable opportunity to assess the impacts of introductions on the currently exhibited animals and aquarium visitors. The impacts of animal introductions were measured through direct observations of seal activity (i.e., ethogram behavioral observations) and visitor activity (i.e., crowd size and visitor length of stay) before and after new seal introductions. This study consisted of two experiments: Experiment 1 (Harbor seal exhibit) and Experiment 2 (Northern fur seal exhibit). In Experiment 1, we found that the introduction had few impacts on the existing harbor seals or on visitor activity. In Experiment 2, the introduction of a new fur seal had significant positive impacts on the existing fur seal, as was seen through increased social behaviors and decreased stereotypic behaviors, as well as a significant increase in crowd size post-introduction. Based on these findings, new animal introductions were associated with neutral to positive changes in both seal and visitor activity. Findings from this study suggest that studying new animal introductions can result in better understanding and promoting positive interactions with existing animals (introduction effects) and likewise positive experiences for zoo and aquarium visitors (introduction experiences).

Impact of animal programming on children's attitudes toward local wildlife

Attitudes toward wildlife can have direct implications on children's interest in conservation behaviors. Animal programs are an example of interactive, educational experiences that have the potential to change attitudes by providing individuals the opportunity to get close to animal ambassadors and participate in engaging conversations about them. We conducted an animal program assessment with summer camps at the Ohio Wildlife Center to quantify changes in children's affiliation with local wildlife and their willingness to live near local wildlife. Campers showed an overall increase in affiliation and willingness scores from before to after an animal program, although with a small effect size. Overall willingness scores were lower than affiliation scores, but there was a significantly larger increase in willingness following the program. We found a strong correlation between affiliation and willingness scores. Overall, the study found that these animal programs positively influenced children's attitudes toward local wildlife and increased their willingness to live near them, suggesting animal programming could be used to decrease human-wildlife conflict. Visually seeing animals in the programs improved attitude scores, even for those not seen in this study, which suggests that program animals can act as an ambassador for other species. This opens the potential for utilizing animal ambassadors as powerful tools in conservation education about threatened and endangered species.

The Animal-Visitor Interaction Protocol (AVIP) for the assessment of Lemur catta walk-in enclosure in zoos

Animal–Visitor Interactions (AVI) are activities offered by zoos and other tourism facilities, in which visitors come into close contact with animals. These activities can promote conservational and educational content, raise conservation mindedness and responsibility for the environment and animal welfare, but if not properly managed can jeopardize visitors’ and animals’ well-being and conservation efforts. The Animal-Visitor Interaction assessment Protocol (AVIP) has been designed to perform an integrated and multidisciplinary assessment of these activities, encompassing the “One Health, One Welfare” approach. AVIP throughout six different steps allows to assess the effects of AVIs both on animals, visitors, and the staff involved. Results can assist zoos to improve management decisions, ensure a transparent evaluation of their activities and promote conservation education goals. Lemurs walk-in enclosures have become increasingly popular among zoos, nevertheless studies focused on their assessment are still scarce. To validate AVIP to this particular AVI, we applied it to assess a walk-in enclosure hosting five Lemur catta in an Italian zoo. Results of behavioural and physiological analyses suggested no changes in animal welfare level and the Animal Welfare Risk Assessment showed low animal welfare risks. Two Visitor Experience Surveys were used to interview 291 visitors, showing that the assessed AVI could help promote the zoo’s conservation objectives and visitor education. Risk Assessment found low and medium risks to the health and safety of visitors. Results were then combined to perform a final ethical assessment. Some potential ethical concerns were detected, but the outcomes indicated that these conflicts were well managed. In the context of recent findings AVIP demonstrated its potential for application also in assessing AVIs involving primates. Our findings confirmed the usefulness of AVIP in assessing and monitoring AVIs, allowing to gain key information in a single process on multiple welfare-related parameters, educational impact, safety of the main stakeholders involved, and ethical concerns.

Molecular Assessments, Statistical Effectiveness Parameters and Genetic Structure of Captive Populations of Tursiops truncatus Using 15 STRs

Simple Summary

The bottlenose dolphins are one of the most used species in entertainment, assisted therapy, education, and research on welfare. However, their maintenance in captivity requires powerful and sensitive tools for preserving their diversity. The number of genetic markers for this purpose remains controversial, restraining the marine species’ genetic diversity determination. We aimed to select 15 hypervariable molecular markers whose statistical parameters were made in 210 captive dolphins from 18 Mexican centers to support their usefulness. The proposed set of markers allowed us to obtain a genetic fingerprint of each dolphin. Additionally, we identified the structure of the captive population, analyzing the groups according to the capture location. Such characterization is key for maintaining the captive species’ biodiversity rates within conservation and reintroduction programs. However, these 15 genetic markers can also be helpful for small- isolated populations, subspecies and other genera of endangered and vulnerable species.

Abstract

Genetic analysis is a conventional way of identifying and monitoring captive and wildlife species. Knowledge of statistical parameters reinforcing their usefulness and effectiveness as powerful tools for preserving diversity is crucial. Although several studies have reported the diversity of cetaceans such as Tursiops truncatus using microsatellites, its informative degree has been poorly reported. Furthermore, the genetic structure of this cetacean has not been fully studied. In the present study, we selected 15 microsatellites with which 210 dolphins were genetically characterized using capillary electrophoresis. The genetic assertiveness of this set of hypervariable markers identified one individual in the range of 6.927e¹³ to 1.806e¹⁶, demonstrating its substantial capability in kinship relationships. The genetic structure of these 210 dolphins was also determined regarding the putative capture origin; a genetic stratification (k = 2) was found. An additional dolphin group of undetermined origin was also characterized to challenge the proficiency of our chosen markers. The set of markers proposed herein could be a helpful tool to guarantee the maintenance of the genetic diversity rates in conservation programs both in Tursiops truncatus and across other odontocetes, Mysticeti and several genera of endangered and vulnerable species.

Factors Affecting Zoo Visitors’ Conservation Beliefs and Knowledge of Large Carnivores in 2009 and a Dozen Years Later

Teaching in a formal learning environment mainly focuses on gaining knowledge, and scarcely on the development of pro-environmental attitudes. Knowledge can also be gained in informal learning institutions, such as zoos, and their potential use in general public education should not be neglected. This paper explores factors influencing the conservation beliefs of zoo visitors about brown bears, grey wolves, and Eurasian lynx. The study undertaken in Zoo Ljubljana (Slovenia) consisted of surveys performed in 2009 (n = 613) and in 2021 (n = 257). The levels of knowledge and education influenced both supporting and opposing beliefs about the three large carnivore species. The gender factor was less uniform: both supporting and opposing beliefs about lynx were demonstrated, but only opposing beliefs about brown bear and wolf. The study indicates that knowledge has the most significant influence on conservation beliefs, thus highlighting the importance of educational and communication activities in management and conservation actions regarding large carnivore species. The varied gender influence suggests that species-specific educational activities should be encouraged.

Conservation Education Impacts of Animal Ambassadors in Zoos

To mitigate the effects of anthropogenic environmental impacts, conservation education (CE) aims to increase public awareness of biodiversity and encourage the uptake of pro-environmental behaviours (PEB). One way of achieving this goal is the use of controlled animal interactions with animal ambassadors to promote CE goals. This study aimed to determine how differing experiences with ambassador Humboldt penguins (Spheniscus humboldti) affected visitors’ knowledge of conservation actions (CA) and their likelihood to perform PEBs in a UK zoo. A quasi-experimental repeated measures questionnaire was used to investigate this aim. Visit types were categorised as (a) ‘penguin parade’, (b) ‘animal encounter’, (c) ‘exhibit viewing’ and (d) a ‘control’ groups. A Kruskal–Wallis test was used to determine if responses to rating scale items related to PEBs differed according to experience. No significant (p > 0.05) differences were detectable between groups. Qualitative data provided in open ended questions relating to CAs were coded into themes and the percentage of responses were calculated for each theme. Whilst the ‘exhibit viewing’ group mentioned sustainable fish significantly more (p = 0.017) than the ‘control’ group, no significant difference was found for any other pair-wise comparison (p > 0.05 in all cases). Overall, this study highlights that zoo visitors gained specific conservation-based knowledge and had higher behavioural intentions towards PEBs than they previously had. However, no evidence was found to suggest that animal encounters improved CE outcomes. To ensure best practice is followed and CE outcomes are considered equally alongside ambassador animal welfare concerns, further research is recommended.

Human Positioning in Close-Encounter Photographs and the Effect on Public Perceptions of Zoo Animals

With the rising popularity of social media, conservation organisations and zoos need to understand its impact on public perceptions of the animals they house and their role in conservation. In addition, many zoos offer close-encounter experiences, and visitors frequently share images from these experiences online. This study measured the effects that viewing such encounter images had on public perceptions of both the zoo and the animals they saw. One of sixteen images was randomly presented to participants in two samples: one of Zoo Community followers and members of Zoos Victoria (n = 963), and a representative sample of the Australian public (n = 1619). Each image featured one of four animals (Eclectus parrot, Kangaroo Island kangaroo, Monteith's leaf insect, Centralian carpet python) and one of four human positions (human and animal touching, human and animal ~30 cm apart, human and animal ~1 m apart, animal alone). Results indicated that viewing different animals and the different human positions within these human-animal encounter images can affect public perceptions of zoo animals. In particular, the closer the proximity of a human to an animal in an image, the more likely respondents were to think that the animal was not displaying a natural behaviour and the more likely it was for General Public respondents to think that the animal would make a good pet. These findings can be used by zoos, wildlife tourism, and media organisations to ensure that they are sending clear, positive, and intended messages about zoo facilities and animals, as well as providing insights into animal encounter images in wider settings.

Challenges and successes to the implementation of a zoo conservation-education program

Zoo conservation-education programs have potential to address biodiversity loss, although evidence of their effectiveness to encourage social change is in its infancy. Moreover, how a program is implemented may influence program efficacy, yet there is little evidence of the factors that shape this process in zoos. Accordingly, through a process evaluation of Zoos Victoria's 'When Balloons Fly" (WBF) conservation-education program against marine debris, we identified barriers and enablers to the implementation of the program which can be addressed to improve future initiatives. Between April-May 2018, 24 Zoos Victoria professionals completed an online survey focussed on identifying challenges and successes in implementing WBF. Four participants additionally completed a follow-up telephone interview. Themes were identified and organised according to the model of diffusion in service organisations (Greenhalgh, Robert, Macfarlane, Bate, & Kyriakidou, 2004). Our results illuminate that features of the organisation (e.g., structure, culture) rather than features of individuals (e.g., skills, motivation) or characteristics of the conservation-education program itself (e.g., messaging), were most influential to implementation success. Based on these findings, attention to the organisational context is critical for promoting and evaluating the success of conservation-education programs and must be given significant attention alongside program characteristics and staff capability to deliver them.

Towards understanding the welfare of cetaceans in accredited zoos and aquariums

Cetaceans are long-lived, social species that are valued as ambassadors inspiring the public to engage in conservation action. Under professional care, they are critical partners with the scientific community to understanding the biology, behavior, physiology, health, and welfare requirements of this taxonomic group. The Cetacean Welfare Study was a highly collaborative research effort among zoos and aquariums accredited by the Alliance for Marine Mammal Parks and Aquariums and/or the Association of Zoos & Aquariums that provided important empirical and comparative information on the care and management of cetaceans. The goal was to identify factors that were related to the welfare of bottlenose dolphins and to develop reference intervals and values for common and novel indicators of health and welfare for common bottlenose dolphins (Tursiops truncatus), Indo-Pacific bottlenose dolphins (Tursiops aduncus), beluga whales (Delphinapterus leucas), and Pacific white-sided dolphins (Lagenorhynchus obliquidens). Data were collected from cetaceans at 43 accredited zoos and aquariums in seven countries in 2018 and 2019. This overview presents a summary of findings from the initial research articles that resulted from the study titled "Towards understanding the welfare of cetaceans in zoos and aquariums." With multiple related objectives, animal-based metrics were used to advance frameworks of clinical care and target key conditions that were associated with good welfare of cetaceans in zoo and aquarium environments. As a result of this collaboration, species-specific reference intervals and values for blood variables and fecal hormone metabolites were developed and are freely available in an iOS application called ZooPhysioTrak. The results suggested that environmental enrichment programs and social management factors were more strongly related to behaviors likely indicative of positive welfare than habitat characteristics for common and Indo-Pacific bottlenose dolphins. These findings can be widely applied to optimize care and future science-based welfare practice.

Assessment of animal management and habitat characteristics associated with social behavior in bottlenose dolphins across zoological facilities

Bottlenose dolphins are a behaviorally complex, social species that display a variety of social behaviors. Because of this, it is important for zoological facilities to strive to ensure animals display species-appropriate levels of social behavior. The current study is part of the multi-institutional study entitled "Towards understanding the welfare of cetaceans in zoos and aquariums" commonly referred to as the Cetacean Welfare Study. All participating facilities were accredited by the Alliance of Marine Mammal Parks and Aquariums and/or the Association of Zoos and Aquariums. Behavioral data were collected on 47 bottlenose dolphins representing two subspecies, Tursiops truncatus and Tursiops aduncus, at 25 facilities. The social behaviors of group related activity (group active) as well as interacting with conspecifics (interact with conspecific) were examined for their relationships to both animal management factors and habitat characteristics. The behavioral state of group active and the rate of interact with conspecific were both positively related to the frequency of receiving new forms of environmental enrichment. Both were inversely related to the random scheduling of environmental enrichment. Additional results suggested interact with conspecific was inversely related with daytime spatial experience and that males displayed group active more than females. Overall, the results suggested that animal management techniques such as the type and timing of enrichment may be more important to enhance social behavior than habitat characteristics or the size of the habitat. Information gained from this study can help facilities with bottlenose dolphins manage their enrichment programs in relation to social behaviors.

Relationships between animal management and habitat characteristics with two potential indicators of welfare for bottlenose dolphins under professional care

Accredited zoos and aquariums continually strive to ensure high levels of animal welfare for the animals under their professional care. Best management practices include conducting research to better understand factors that lead to optimal welfare and then turning findings into practice. The current study is part of the larger Cetacean Welfare Study or more formally, "Towards understanding the welfare of cetaceans in zoos and aquariums." Facilities participating in the study were accredited by the Alliance of Marine Mammal Parks and Aquariums and/or the Association of Zoos and Aquariums. Animal management factors and habitat characteristics were examined in relation to two potential indicators of welfare for common (Tursiops truncatus) and Indo-Pacific (Tursiops aduncus) bottlenose dolphins. Specifically, we examined environmental enrichment, animal training, and habitat characteristics that were significantly related to behavioral diversity and route tracing, a form of stereotypic behavior. Behavior was recorded from 47 animals at 25 facilities around the world. Overall, the rate of route tracing behavior observed during the study was very low and few animal management factors or habitat characteristics were found to be related to this behavior. One factor, enrichment diversity, had a significant positive relationship with route tracing and an inverse relationship with behavioral diversity. This finding may be a product of a response mounted by animal care specialists to the behavior as opposed to a cause. Animals that engaged in this behavior were likely provided more diverse enrichment in attempts to ameliorate the stereotypic behavior. However, multiple factors were found to significantly relate to behavioral diversity, a potential positive indicator of welfare for bottlenose dolphins. Dolphins that were trained on a predictable schedule had higher behavioral diversity than those on a semi-predictable schedule. There was a positive significant relationship between behavioral diversity and the number of habitats to which an animal had access, and a significant inverse relationship with the maximum depth of the habitat. Finally, animals that were split into groups and reunited or rotated between subgroups had higher behavioral diversity than animals managed in the same group. Information gained from the current study suggested that animal management techniques may be more important in ensuring good welfare for bottlenose dolphins than focusing on habitat size.

Visitor attachment to dolphins during an interaction programme, are there implications to dolphin behavior?

Millions of people visit zoos and aquariums globally each year, with a smaller number choosing to participate in animal interaction programmes which allows visitors closer contact with individual animals. These are reportedly having mixed effects in increasing conservation-related behaviors. Human-animal interactions (HAIs) during these programmes are generally positive experiences for the human participants, however are there behavioral implications for the animals involved? The Bottlenose Dolphin (Tursiops truncatus) is the most widely used cetacean for dolphin interactions, known as "swim with dolphin" (SWD) programmes. This study investigated visitor attachment to the dolphins they interacted with, whilst assessing behavioral implications of the dolphins. A total of 41 visitors to a Spanish dolphinarium, who participated in a SWD were surveyed using a modified version of the Lexington Attachment to Pets Scale. Alongside this, 15-min continuous focal samples monitored three female dolphins (D1, D2, and D3) aged 22-40, split into pre (n = 96), during (n = 96) and post (n = 96) SWD. 80% of visitors reported a sense of attachment to the dolphin they interacted with. An exploratory factor analysis extracted three factors from the survey, these were "relationships," "emotional attachment," and "non-attachment." A Friedmans two-way analysis of variance produced significant results for some behavior categories for each individual, including locomotory (D1: F₂  = 9.556, p < .01), rest (D2: F₂  = 14, p < .01, D3: F₂  = 10.889, p < .01) and individual play (D1: F₂  = 11.677, p < .01 D2: F₂  = 6.353, p < .05) however, pairwise comparison showed no differences pre-post SWD. In this context it can be implied that participating in the SWD was neither enriching nor aversive for the individual animals, although due to the small sample size further research is required. As visitors reported a sense of attachment post HAI, this can have applications in improving conservation education during SWD. This study has provided scope for further research into methods that facilities can use to utilize the emotional attachment developed to individual animals to facilitate learning about conservation issues.

Conservation Education: Are Zoo Animals Effective Ambassadors and Is There Any Cost to Their Welfare?

Animal ambassador encounters (AAE), where visitors come into close-contact with animals, are popular in zoos and are advocated as promoting connection to wild species. However, educational and animal-welfare implications are relatively unknown. We conducted a systematic literature review (PRISMA) to investigate visitor and animal outcomes of AAE. We identified 19 peer reviewed articles and 13 other records focused on AAEs. Although we found net positive or neutral impacts overall, several studies indicated that high-intensity visitor contact and long-term exposure may be detrimental to animal welfare. Most studies lacked rigour and claims were based on an absence of negative impacts rather than evidence of benefits. Multiple publications were derived from the same datasets and there were no standardised measures for either welfare or education impacts. Of the peer-reviewed articles, just two considered both education and welfare. Education studies often used perceived learning or only post-experience testing. Welfare studies used small samples (median n = 4; range 1–59), and limited measures of welfare. In order to justify the continued use of AAEs in modern zoos, animal welfare costs must be proven to be minimal whilst having demonstrable and substantial visitor educational value. Large-scale, standardised impact assessments of both education and welfare impacts are needed.

Visitor Attitudes Toward Little Penguins (Eudyptula minor) at Two Australian Zoos

This study identified and compared the attitudes of visitors toward zoo-housed little penguins, their enclosure and visitor experience that may influence the way visitors behave toward little penguins at two Australian zoos. Visitor attitudes were assessed using an anonymous questionnaire, targeting visitor beliefs, and experiences, where visitors were randomly approached at the penguin exhibit after they had finished viewing the penguins. Visitors were given two options to complete the questionnaire, on an iPad during their zoo visit or online (URL sent via email) after their zoo visit. A total of 638 participants (495 at Melbourne Zoo and 143 at Taronga Zoo) completed the questionnaire, 42% were completed onsite during their zoo visit and 58% were completed online after their zoo visit. Most participants were living in Australia, non-zoo members, female, previously or currently owned a pet, aged between 26 and 35 years and had a University degree. Results showed that the attitude dimensions of visitors were consistent between the two zoos which indicates that these measures of attitudes were stable over time and location. Overall, visitors at both zoos had positive attitudes toward little penguins, penguin welfare, the enclosure, and visitor experience. However, whether these positive attitudes and positive visitor experience influenced the way visitors behaved toward the penguins remains unclear. There were some differences in visitor attitudes toward the perceived “aggressiveness” and “timidness” of little penguins, “negative penguin welfare”, “experience with the penguins”, “learning”, “visual barriers” and the way visitors rated their overall experience at the penguin enclosure. While the reasons for the differences in visitor attitudes and visitor experience between the zoos were not clear, some factors such as penguin behavior and enclosure design, may have been attributable to these differences. Also, a relationship was found between visitor attitudes and how visitors rated the welfare of penguins, the enclosure and visitor experience at the enclosure; more positive visitor attitudes were associated with higher ratings of penguin welfare, the enclosure and visitor experience. The practical implications of these results for zoos is unclear because the differences in visitor attitudes were numerically small. This requires further comparisons between zoos or enclosures that are more markedly different than the penguin enclosures in the present study and further research on how visitors assess zoo animals, enclosures and visitor experience.

Connecting High School Students With Nature - How Different Guided Tours in the Influence the Success of Extracurricular Educational Programs

Zoos attract millions of visitors every year, many of whom are schoolchildren. For this reason, zoos are important institutions for the environmental education of future generations. Empirical studies on the educational impact of environmental education programs in zoos are still rare. To address this issue, we conducted two studies: In study 1, we investigated students’ interests in different biological topics, including zoos (n = 1,587). Data analysis of individual topics revealed large differences of interest, with advanced students showing less interest in zoos. In study 2, we invited school classes of this age group to visit different guided tours at the zoo and tested connection to nature before and after each educational intervention (n = 608). The results showed that the guided tours are an effective tool to raise students’ connection to nature. Add-on components have the potential to further promote connection to nature. The education programs are most effective with students with a low initial nature connection.

What Is the Zoo Experience? How Zoos Impact a Visitor's Behaviors, Perceptions, and Conservation Efforts

Modern zoos strive to educate visitors about zoo animals and their wild counterparts' conservation needs while fostering appreciation for wildlife in general. This research review examines how zoos influence those who visit them. Much of the research to-date examines zoo visitors' behaviors and perceptions in relation to specific exhibits, animals, and/or programs. In general, visitors have more positive perceptions and behaviors about zoos, their animals, and conservation initiatives the more they interact with animals, naturalistic exhibits, and zoo programming/staff. Furthermore, zoo visitors are receptive to conservation messaging and initiatives at zoos and are more likely to participate in on-site conservation opportunities as opposed to after their visits. The research also suggests that repeat visitors are even more inclined to seek out conservation efforts compared to those visiting zoos for the first time. While current research suggests that repeat visitors are more likely to engage in conservation efforts, little is known about causal factors related to such findings, and almost no research exists to-date comparing the conservation efforts of visitors vs. non-visitors. This latter comparison will likely play a greater role in future zoo visitor research, since it poses one of the most important metrics for evaluating the specific effects visiting a zoo can have on people engaging in conservation efforts in general.

A Protocol for the Ethical Assessment of Wild Animal-Visitor Interactions (AVIP) Evaluating Animal Welfare, Education, and Conservation Outcomes

Due to the popularity of wild animal-visitor interactions (AVIs), there is a need for an ethical assessment of their impact on animal welfare, education, and conservation. The protocol presented in this study is designed to evaluate such interactions on an integrated level, using a transparent analysis of all the aspects involved, including all the stakeholders and the potential conflicts of values. The protocol consists of a six-step process encompassing dedicated data acquisition and a specific ethical assessment. When the protocol was applied to assess a "giraffe feeding" interaction, steps devoted to data acquisition found that animal welfare risks were low, and that visitors described giraffes with emotionally linked descriptors more often after the interaction. The net promoter score, which refers to how likely visitors would recommend to a friend to join the animal-visitor interaction, was 74%. The subsequent ethical assessment, which consisted of a comparison of the results of the previous steps with an ethical matrix highlighting the ideal situation for all stakeholders' interests, allowed the overall identification of the ethical concerns entailed by the interaction. A final ethical checklist of the examined AVI had a "yes" in entries regarding animal welfare, emotional, and conservation mindedness outcomes and ethical assessment.

Reassessing public opinion of captive cetacean attractions with a photo elicitation survey

Background

Captive cetacean attractions are growing in number globally, their operators citing entertainment, education, and conservation as benefits. Those for and against developing such attractions claim public support. Previous public opinion research, however, shows little consensus, partly due to the introduction of biases in study design that influence participants' responses. Those involved in, or concerned with, developing and licensing these attractions need to better understand what drives the lack of consensus to take socially-acceptable decisions.

Methods

We reviewed previous research on public opinion of cetacean captivity, noting possible sources of bias. Survey question wording can be a major source of introduced bias, so we used an open-ended photo elicitation approach. We showed tourists in the Turks Caicos Islands (N = 292) images of a marine mammal park (MMP) killer whale show and a swim-with-the-dolphins (SWTD) attraction and asked for their qualitative comments on the potential development of each. They also indicated how likely they would be to visit each on a Likert scale.

Results

Respondents were generally against visiting MMP killer whale shows, with 60.9% not likely to visit. SWTD attractions were more popular; 60.3% were likely to visit. For SWTD, USA residents were more likely to visit; older respondents and those staying in all-inclusive resorts were less likely. Those staying in all-inclusive resorts were also less likely to visit MMP killer whale shows. The great majority of qualitative comments centred on either entertainment value or animal welfare concerns. There were very few, if any, comments on the education or conservation value of these attractions.

Discussion

Our findings contradict several previous studies on public opinion of captive cetaceans that did not use photo elicitation. The support shown for MMP killer whale shows in this survey was well below that claimed by studies conducted on behalf of captive cetacean attraction operators. Opposition to SWTD was also noticeably lower than that found in surveys conducted with wild cetacean tourism participants. This difference can likely be attributed to the different survey populations and settings, but this variation is also very likely attributable to researcher-introduced bias. While photo selection can introduce bias, photo elicitation reduces reliance on pre-scripted questions and responses, and seems to effectively reduce other forms of bias. Allowing open-ended responses, where participants responded to an image, seems to have given a more representative understanding of what is at the forefront of the public's mind than closed questioning. These conclusions, among others made in this study, suggest that development decisions for captive cetacean attractions are being made on imprecise data. Going forward, data collected via responder-led, open-ended, bias-minimising approaches should at least be considered when informing such decisions.

Religious Travellers’ Improved Attitude towards Nature

Pilgrimage is one of the most ancient forms of tourism. Nowadays, it is becoming a mass phenomenon that can lead to serious problems of environmental degradation in valuable sites. In this work, we have analysed by means of a structural equation model how religious consciousness is inspired in the religiosity/spirituality of each pilgrim. It could predict its effects on tourists regarding an improved (i.e., sensitised and more sustainable) attitude towards nature. The study was carried out in Guadalupe, Spain, which is a commonly known pilgrimage destination since 1389. A total of 203 visitors were surveyed using a questionnaire composed of 16 questions, divided into 4 dimensions (enriched attitudes toward nature, religious consciousness, sustainable development, and environmental human development), which were used as constructs in the model. The results showed how religious consciousness positively influences sustainable development (β = 0.657, t = 11.306) and environmental human development (β = 0.566, t = 8.255) explaining 75.6% of religious travellers’ more sensitive attitudes towards nature. Our findings suggest that a deeper research, on the role played by religiosity as a seed of fostering sustainability, is still needed.

Zoo visitor perceptions, attitudes, and conservation intent after viewing African elephants at the San Diego Zoo Safari Park

Elephants in the wild face several conservation issues. With the rebranding of zoos as conservation and education pioneers, they have the ability to both educate and inspire guests to action. The purpose of this research was to analyze visitor perceptions and attitudes toward elephant conservation and outcomes post-exhibit visit. A one-page survey was randomly administered to assess perceptions of elephant behavior, attitudes about elephant conservation, and intended conservation-related outcomes from September 2013 to January 2014. Principle component analysis identified three major components: concern for elephants in zoos, importance of elephants in the wild, and modification of nature. Visitors who scored highly on conservation intent were those with positive attitudes towards elephants in the wild and negative attitudes regarding the modification of nature. The greatest changes in conservation intent were a result of a self-reported up-close encounter and the ability to witness active behaviors. Providing guests with the opportunity to witness or experience such occurrences may aid in a more successful delivery of the zoo's conservation message. Further research into guest emotions and affective states in relation to viewing elephants in a zoological institution would provide greater insight into improving the guest experience and helping zoos meet their conservation mission.

Advancing Behavior Analysis in Zoos and Aquariums

Zoos, aquariums, and other captive animal facilities offer promising opportunities to advance the science and practice of behavior analysis. Zoos and aquariums are necessarily concerned with the health and well-being of their charges and are held to a high standard by their supporters (visitors, members, and donors), organized critics, and the media. Zoos and aquariums offer unique venues for teaching and research and a locus for expanding the footprint of behavior analysis. In North America, Europe, and the UK, formal agreements between zoos, aquariums, and university graduate departments have been operating successfully for decades. To expand on this model, it will be necessary to help zoo and aquarium managers throughout the world to recognize the value of behavior analysis in the delivery of essential animal health and welfare services. Academic institutions, administrators, and invested faculty should consider the utility of training students to meet the growing needs of applied behavior analysis in zoos and aquariums and other animal facilities such as primate research centers, sanctuaries, and rescue centers.
