Technology at the Zoo: The Influence of a Touchscreen Computer on Orangutans and Zoo Visitors

A computer‐controlled touchscreen apparatus (hereafter referred to as “touchscreen”) in the orangutan exhibit at Zoo Atlanta provides enrichment to the animals and allows cognitive research to take place on exhibit. This study investigated the impact of the touchscreen on orangutan behavior and visibility, as well as its impact on zoo visitors. Despite previous research suggesting that providing a single computer system may negatively affect orangutan behavior, there was not a significant increase in aggression, stereotypic, or distress‐related behaviors following the activation of the on‐exhibit touchscreen. We also investigated the possibility that zoo visitors may be negatively affected by technology because it deviates from naturalism. However, we did not find a change in stay time or overall experience rating when the computer was turned on. This research was the first to assess visitor attitudes toward technology at the zoo, and we found that visitors report highly positive attitudes about technology for both animals and visitors. If subjects visited the exhibit when the computer was turned on, they more strongly agreed that orangutans benefit from interacting with computerized enrichment. This study is the first investigation of an on‐exhibit touchscreen in group‐housed apes; our findings of no negative effects on the animals or zoo visitors and positive attitudes toward technology suggest a significant value of this practice.

Visitor interest in zoo animals and the implications for collection planning and zoo education programmes

As zoos have sought to further their conservation missions, they have become powerful providers of environmental education. Outside of “formal” education initiatives, such as those designed for school and other organized groups, or structured public talks programmes, much of the learning potential that the zoo has to offer is around the viewing of animals and the response of visitors to them. In this, zoo learning is a very personal construct, develops from the previous knowledge, and experiences and motivations of each individual. In this article, we make the assertion that learning potential, although difficult to quantify, is very much related to the attractiveness of animal species and the interest that visitors show in them. Using standard behaviorist measures of attraction and interest (the proportion of visitors that stop and for how long), we analyzed the relative interest in 40 zoo species held in a modern UK zoo and the variables that are significant in predicting that popularity. Further to this, the suggestion is made that the zoo collection planning process could use such information to make more informed decisions about which species should be housed for their educational value. Taxonomic grouping was found to be the most significant predictor of visitor interest—that is, visitors were far more interested in mammals than any other group—although body size (length), increasing animal activity and whether the species was the primary or “flagship” species in an exhibit or not, were all found to have a significant bearing on visitor interest.

Assessing the Effects of New Primate Exhibits on Zoo Visitors' Attitudes and Perceptions by Using Three Different Assessment Methods

ABSTRACT

Using three different methods, this study investigated how zoo visitors behaved in response to both old and new exhibits of four nonhuman primate species and how they perceived these primates. On-site observations showed that zoo visitors were more likely to stop in front of new exhibits and spend more time viewing new exhibits compared with old exhibits. Response to an on-site questionnaire also showed that zoo visitors perceived primates in the new exhibits more positively than the same animals in the old exhibits. The results from these two types of local assessment indicate that the attractiveness and holding power of the new exhibits was greater than that of the old. However, the results of a questionnaire given to zoo visitors on leaving the zoo showed that the preference ranks of the visitors for the four primate species did not increase after the new exhibits were established, indicating that the new exhibits did not change the zoo visitors' perception of primates relative to other zoo animals. Using all three assessment methods appears to be of considerable value for the assessment of visitors' perceptions towards new exhibits in terms of both the immediate locality and the zoo as a whole.     

Public Attitudes toward the Use of Animals in Research: Effects of Invasiveness,Genetic Modification and Regulation

ABSTRACT

This study describes an online public engagement experiment aimed at investigating how acceptance of animal-based research is affected by: (a) the presence of regulations that govern the use of nonhuman animals in laboratories, (b) the invasiveness of procedures, and (c) the use of genetically modified (GM) animals. To meet these aims, participants were asked if they were willing to accept the use of pigs in different scenarios involving agricultural research. Two-thirds of the 681 participants were female and the majority (58%) were young (19–29 years old) with college or university level education (62%). Participants came from 26 different countries, with the United States, Canada, and the United Kingdom being the top three countries represented. Participants who self-identified as being vegetarians, familiar with animal welfare, animal advocates, environmental advocates, and familiar with animal research were significantly more likely to be opposed to animal-based research. Older participants were significantly less likely to oppose animal-based research. Support significantly decreased when animal-based research involved an invasive procedure or GM animals. Support for invasive research significantly increased when regulation was in place, but regulation had less effect on acceptance of GM animal use. Comments provided by participants illustrated different decision-making strategies regarding different types of animal-based research. Given the increasing use of GM animals in research, more effort is required to understand people's concerns regarding this type of animal use and to determine how these concerns should be reflected in policy.     

Acceptability of Animal-Assisted Therapy: Attitudes toward AAT,Psychotherapy, and Medication for the Treatment of Child Disruptive Behavioral Problems

Animal-assisted therapies (AATs) are not widely promoted in routine mental healthcare but represent a viable treatment option given positive perceptions of pets and growing evidence that animals provide meaningful contribution to psychological wellbeing. Relatively little is known about the general public's attitude toward AATs, especially in relation to more commonly used alternatives. This study compared the acceptability of four different treatment options (AAT, medication, psychotherapy, and no active treatment) for common externalizing behaviors in children. Parents from a community sample (N = 189) were presented with vignettes describing a child with symptoms of an externalizing behavior disorder and were asked to rate the acceptability of the four different treatment options. Participants rated AAT as a highly acceptable form of treatment and more acceptable than no active treatment and medication. However, AAT was rated as less acceptable than psychotherapy. Experiences with animals (both positive and negative) were unrelated to the acceptability of AAT. These findings suggest that AAT is viewed as a highly acceptable form of treatment for common externalizing behaviors and should be more systematically investigated as a treatment for children's mental health problems.     

Feeding Behavior of Purple‐throated Fruitcrow (Querula purpurata: Cotingidae) in the Colombian Amazon and Its Implications for Seed Dispersal1

We studied some feeding behaviors of the purple‐throated fruitcrow (Querula purpurata) in two Colombian Amazonian forests, which affect the primary seed dispersal of the plants on which it feeds. Visit length, number of fruits removed and dispersed, feeding rates, and fruit‐handling times were compared to those obtained for two other cotingas feeding on the same fruiting trees. Querula purpurata exhibited shorter visits (98 sec) and fruit‐handling times (4 sec), and higher mean feeding rates (1.6 fruits/min) than Phoenicircus nigricollis and Cotinga cayana. In contrast, P. nigricollis dispersed the highest number of seeds of four of the five tree species studied. Although Q. purpurata and P. nigricollis exhibited feeding behaviors that increase seed dispersal, Q. purpurata may be more important in the transport of seeds between habitats, while P. nigricollis may be a major seed disperser within the primary forest.     

A Retrospective Study of Mortality in Varanid Lizards (Reptilia:Squamata:Varanidae) at the Bronx Zoo: Implications for Husbandry and Reproductive Management in Zoos

Varanid lizards have been maintained in zoological parks for more than a century, yet few studies to date have attempted to pinpoint significant health issues affecting their management or areas of captive husbandry that are in need of improvement. In an effort to identify and better understand some of the husbandry‐related challenges and health issues specifically affecting varanids in zoos, this study examined mortality in 16 species maintained at the Bronx Zoo between 1968 and 2009. Out of 108 records reviewed, complete necropsy reports were available for 85 individuals. Infection‐related processes including bacterial (15.3%), protozoal (12.9%), nematode (9.4%), and fungal (3.5%) infections accounted for the greatest number of deaths (47.1%). Noninfectious diseases including female reproductive disorders (7.1%), neoplasia (7.1%), gout (10.8%), and hemipenal prolapse (1.3%) accounted for 29.4% of deaths. Multiple disease agents were responsible for 5.9% of deaths, and a cause for death could not be determined for 17.7% of individuals. Reproductive complications accounted for 11.5% of female deaths, but were identified in 23.1% of females. Although not necessarily the cause for death, gout was present in 18.8% of individuals. Differences in mortality between species, genders, and origin (captive‐bred vs. wild‐caught) were also evaluated. The results of this study corroborate earlier findings that identify bacterial infections, neoplasia, female reproductive disorders, gout, and endoparasitism as major sources of mortality in captive varanids. In light of these results, we discuss potential etiologies and offer recommendations for improving captive management practices in zoos.

MOET: a web-based gene set enrichment tool at the Rat Genome Database for multiontology and multispecies analyses

Biological interpretation of a large amount of gene or protein data is complex. Ontology analysis tools are imperative in finding functional similarities through overrepresentation or enrichment of terms associated with the input gene or protein lists. However, most tools are limited by their ability to do ontology-specific and species-limited analyses. Furthermore, some enrichment tools are not updated frequently with recent information from databases, thus giving users inaccurate, outdated or uninformative data. Here, we present MOET or the Multi-Ontology Enrichment Tool (v.1 released in April 2019 and v.2 released in May 2021), an ontology analysis tool leveraging data that the Rat Genome Database (RGD) integrated from in-house expert curation and external databases including the National Center for Biotechnology Information (NCBI), Mouse Genome Informatics (MGI), The Kyoto Encyclopedia of Genes and Genomes (KEGG), The Gene Ontology Resource, UniProt-GOA, and others. Given a gene or protein list, MOET analysis identifies significantly overrepresented ontology terms using a hypergeometric test and provides nominal and Bonferroni corrected P-values and odds ratios for the overrepresented terms. The results are shown as a downloadable list of terms with and without Bonferroni correction, and a graph of the P-values and number of annotated genes for each term in the list. MOET can be accessed freely from https://rgd.mcw.edu/rgdweb/enrichment/start.html.     

Assessing deer densities and impacts at the appropriate level for management: a review of methodologies for use beyond the site scale

• 1 Population density alone is unlikely to be a good predictor of the impacts of deer on their environment. The assessment of management requirements should therefore be based on assessment of deer impacts, alongside estimates of density.
• 2 Both density and impacts need to be monitored at a landscape scale, and there is a need to develop appropriate methodologies that allow managers to consider the current and likely future impact of deer.
• 3 The relevant scale for assessment (and management) varies both with deer species and context of impact, but should always encompass at least the estimated biological range of the population of deer present in an area. Some impacts (e.g. deer–vehicle collisions, and risks of disease transmission) may need to be assessed at a wider regional level.
• 4 In this review we consider various approaches available for assessing: absolute or relative animal abundance; impacts of ungulates on agriculture, forestry, amenity woodlands and other conservation sites; impacts on public safety (e.g. through road traffic accidents) and on humans or livestock through potential spread of disease.
• 5 In each case the advantages and disadvantages of a variety of methods are considered, before recommendations are made for methodologies which are sufficiently accurate, sufficiently robust and sufficiently practical to be favoured in a management context.
• 6 To address impacts at the landscape scale requires management policies that integrate information on both positive and negative impacts of deer in order to ensure appropriate and holistic management. We present a decision‐support framework suitable for use within the UK, using inputs from a variety of possible impact types to assist managers and forewarn of situations where current management may need to be modified.
