Does the absence of zoo visitors during the COVID-19 pandemic impact Gorilla behavior?

Whether or not primates are behaviorally affected by the presence of visitors in a zoo setting is a question of great relevance to zoo animal well-being. The situation imposed by the COVID-19 pandemic provided an unusual opportunity to examine how the absence of visitors impacts behavior. We took advantage of this opportunity to study the behavior of a gorilla troop during periods of no-visitors compared to our long-term database on gorilla behavior during normal zoo operations. While there were notable individual differences in response to visitors, we found no significant relationship between presence of visitors and behavior. These results suggest that the presence of visitors does not have a significant impact on behavior and well-being of zoo-housed gorillas.

The impact of social isolation on health and behavior in Drosophila melanogaster and beyond

Many organisms, including humans, have evolved dynamic social behaviors to promote survival. Public health studies show that isolation from social groups is a major risk factor for adverse health outcomes in humans, but these studies lack mechanistic understanding. Animal models can provide insight into the molecular and neural mechanisms underlying how social isolation impacts health through investigations using genetic, genomic, molecular, and neuroscience methods. In this review, we discuss Drosophila melanogaster as a robust genetic model for studying the effects of social isolation and for developing a mechanistic understanding of the perception of social isolation and how it impacts health.

Understanding the performance of truffle dogs

Trained dogs can detect many biochemical traces, from the most hostile, such as COVID-19, to the most expensive, such as truffles. However, it is still unclear how the interplay of genetic disposition, education, experience, personality, and environmental conditions influences the performance of dogs. Here, we combine published evidence with the knowledge of truffle hunters to assess direct and indirect factors that affect the hunting performance of truffle dogs. Since the transport of truffle aroma into the canine nasal cavity is most puzzling, we propose 5 experiments to further investigate the role of weather conditions, soil parameters, and bacterial composition on the dispersal of truffle volatiles perceived by trained dogs. We also suggest exploring whether the application of multiple dogs increases the success of truffle hunting. Moreover, we argue that interdisciplinary research on dog behavior and performance, including insights from veterinary science and comparative psychology as well as the experience of truffle hunters and farmers, is needed to improve the quantity and quality of truffle harvests.

The Role of Animal Health Components in a Biosurveillance System: Concept and Demonstration

Biosurveillance defines the process of gathering, integrating, interpreting, and communicating essential information related to all-hazards threats or disease activity affecting human, animal, or plant health to achieve early detection and warning, contribute to overall situational awareness of the health aspects of an incident, and to enable better decision making for action at all levels. Animal health surveillance is an important component within biosurveillance systems comprising a continuum of activities from detecting biological threats, to analyzing relevant data, to managing identified threats, and embracing a One Health concept. The animal health community can strengthen biosurveillance by adopting various developments such as increasing the alignment, engagement, and participation of stakeholders in surveillance systems, exploring new data streams, improving integration and analysis of data streams for decision-making, enhancing research and application of social sciences and behavioral methods in animal health surveillance, and performing timely evaluation of surveillance systems. The aim of this paper is to explore components of a biosurveillance system from an animal health perspective and identify opportunities for the animal health surveillance community to enhance biosurveillance. Structural and operational diagrams are presented to demonstrate the required components and relevant data of animal health surveillance as an effective part within a biosurveillance system.

Special Issue: One health. (Special Issue: One health.)

This special issue consists of 17 papers dealing with issues animal health (captive and wild primates), environmental health (rain forests and mountain areas), and human health (the role of religion in One Health, lessons from the Hanuman langur (Semnopithecus entellus) and other human-non-human primate interactions,and Covid-19).

Reflections from the team: co-creating visual media about ecological processes for young people. (Special Issue: Nature on screen: The implications of visual media for human-nature relationships.)

Many migratory fish populations are declining, threatened by human-induced pressures such as habitat loss and fragmentation caused by dams, roads, land use change, climate change and pollution. However, public awareness of fish migration and associated human pressures remains limited. It is important to communicate about hard-to-see and complex environmental topics and issues, such as fish migration, with young people, who stand to be the most affected by ongoing global changes. Young people are also at a critical stage in their attitude formation and may be particularly receptive to learning enrichment and engagement for behaviour change about environmental issues. Arts-based methods can be particularly effective in fostering broad personal connections with nature, especially for complex topics like fish migration. The collaborative and creative processes involved in developing such media often lack critique, which limits learning from previous experiences. In this article, we reflect on the co-creation of the Shout Trout Workout (STW), a lyric poem, comic and music video for 8- to 14-year-olds, designed to entertain, engage and enrich learning about migratory fishes and aquatic environments. We chart the process of creation, including conception of ideas, writing the poem, fact-checking and developing the storyline with scientists and creating a comic and music video with visual artists and musicians. We explore some of the challenges and merits of collaborative working, consider the impacts of the COVID-19 pandemic on the creative and initial engagement process and share what we learned about creative input, communication and respect. We also discuss how the experience shaped our thoughts about the nature of co-creation itself, and how in creating STW, collaborators contributed to the process in multiple, nuanced and unanticipated ways (e.g. artistic input, ideas, science, dissemination), representing a spectrum of co-creative practice. We hope that sharing our experiences and reflections is useful and inspiring for other cross-disciplinary collaborations, and for those who aim to create learning enrichment and engagement material about ecological processes and environmental issues for young people.

Behavioral–biological surveillance of emerging infectious diseases among a dynamic cohort in Thailand

Background Interactions between humans and animals are the key elements of zoonotic spillover leading to zoonotic disease emergence. Research to understand the high-risk behaviors associated with disease transmission at the human-animal interface is limited, and few consider regional and local contexts. Objective This study employed an integrated behavioral–biological surveillance approach for the early detection of novel and known zoonotic viruses in potentially high-risk populations, in an effort to identify risk factors for spillover and to determine potential foci for risk-mitigation measures. Method Participants were enrolled at two community-based sites (n = 472) in eastern and western Thailand and two hospital (clinical) sites (n = 206) in northeastern and central Thailand. A behavioral questionnaire was administered to understand participants’ demographics, living conditions, health history, and animal-contact behaviors and attitudes. Biological specimens were tested for coronaviruses, filoviruses, flaviviruses, influenza viruses, and paramyxoviruses using pan (consensus) RNA Virus assays. Results Overall 61/678 (9%) of participants tested positive for the viral families screened which included influenza viruses (75%), paramyxoviruses (15%), human coronaviruses (3%), flaviviruses (3%), and enteroviruses (3%). The most salient predictors of reporting unusual symptoms (i.e., any illness or sickness that is not known or recognized in the community or diagnosed by medical providers) in the past year were having other household members who had unusual symptoms and being scratched or bitten by animals in the same year. Many participants reported raising and handling poultry (10.3% and 24.2%), swine (2%, 14.6%), and cattle (4.9%, 7.8%) and several participants also reported eating raw or undercooked meat of these animals (2.2%, 5.5%, 10.3% respectively). Twenty four participants (3.5%) reported handling bats or having bats in the house roof. Gender, age, and livelihood activities were shown to be significantly associated with participants’ interactions with animals. Participants’ knowledge of risks influenced their health-seeking behavior. Conclusion The results suggest that there is a high level of interaction between humans, livestock, and wild animals in communities at sites we investigated in Thailand. This study highlights important differences among demographic and occupational risk factors as they relate to animal contact and zoonotic disease risk, which can be used by policymakers and local public health programs to build more effective surveillance strategies and behavior-focused interventions.

Mountain lions reducemovement, increase efficiency during the COVID-19 shutdown

Wildlife strongly alter behaviour in response to human disturbance;however, fundamental questions remain regarding the influence of human infrastructure and activity on animal movement. The Covid-19 pandemic created a natural experiment providing an opportunity to evaluate wildlife movement during a period of greatly reduced human activity. Speculation in scientific reviews and the media suggested that wildlife might be increasing movement and colonizing urban landscapes during pandemic slowdowns. However, theory predicts that animals should move and use space as efficiently as possible, suggesting that movement might actually be reduced relative to decreased human activity. The researchers quantified space use, movement, and resource-selection of 12 GPS-collared mountain lions (eight females, four males) occupying parklands in greater Los Angeles during the Spring 2020 California stay-at-home order when human activity was far below normal. The researchers also tested the hypothesis that reduced traffic on Los Angeles area roadways increased permeability of these barriers to animal movement. Contrary to expectations that wildlife roamed more widely during pandemic shutdowns, resident mountain lions used smaller areas and moved shorter distances relative to their historical behaviour in greater Los Angeles. They also relaxed avoidance of anthropogenic landscape features such as trails and development, which likely facilitated increased travelling efficiency. However, there was no detectable change in road-crossing, despite reduced traffic volume. Our results support the theoretical prediction that animals maximize movement efficiency and suggest that carnivores incur energetic costs while avoiding humans. While mountain lions may restrict movement at the landscape level relative to barriers, they appear to increase distances moved at finer scales when avoiding human activity - highlighting the scale-dependent nature of animal responses to human disturbance. Avoiding humans can reduce direct mortality of large carnivores and is often suggested to be an important mechanism promoting coexistence in shared landscapes. However, energetic costs incurred by increased movement and space-use while avoiding human activity may have important consequences for population viability, predator-prey interactions, community structure, and human-wildlife conflict. Management providing sufficient wild prey and education regarding best practices for protection of domestic animals are important for conserving large carnivores in human-dominated landscapes.

Behavioral Assessment of Six Reptile Species during a Temporary Zoo Closure and Reopening.

Although reptiles are commonly housed in zoos and aquariums, their welfare is understudied for the diversity of species housed and the taxon's current captive population size. The sensory abilities of reptiles have adapted to the varied ecological niches they inhabit, and these evolutionary adaptations impact how reptiles perceive the stimuli around them-including zoo visitors. This study aimed to assess visitor effects on small groups of six reptile species during a temporary zoo closure due to COVID-19 by measuring behavioral diversity, use of space (measured by a spread of participation index), and select behaviors. The species assessed showed diverse responses. The Catalina Island rattlesnakes (Crotalus catalinensis) demonstrated increased investigation and behavioral diversity after the zoo reopened compared to when the zoo was closed, but the European glass lizards (Pseudopus apodus) showed decreases in the amount of time spent exposed to the observers' view and in their evenness of space use after the zoo was reopened to visitors. The other species, including beaded lizards (Heloderma horridum), Sonoran spiny-tailed iguana (Ctenosaura macrolopha), Arrau turtles (Podocnemis expansa), and dwarf caimans (Paleosuchus palpebrosus), had intermediate changes in their responses to visitor presence.

Exploring the Effect of the COVID-19 Zoo Closure Period on Flamingo Behaviour and Enclosure Use at Two Institutions

Simple Summary: The COVID-19 pandemic led to widespread closures of zoos, which afforded an opportunity to compare the behaviour of two species of flamingo at two zoos between a period of visitor absence to a period of normal visitor presence. We found that the behaviours performed and the enclosure areas used by the flamingos were consistent over time, indicating that the return of visitors did not unduly alarm the birds. One of the flamingo flocks showed minor changes in some behaviours but these effects were explained by analysis of weather influences on flamingo behaviour and visitor numbers. The constant interaction with zookeepers and the gradual opening to visitors are likely to have positively influenced the birds' behaviour and responses to the zoos' re-openings. Visitors can influence the behaviour of zoo animals through their auditory and visual presence, with mixed findings of negative, neutral, and positive effects on welfare. This study opportunistically utilised the UK-wide COVID-19 period of zoo closure to investigate the activity and enclosure usage of Greater (Phoenicopterus roseus) and Chilean (P. chilensis) Flamingos housed at two zoos. Flamingo behaviour at both sites was observed during the last week of a three-month closure period and the immediate reopening of the zoos. Photographic data were collected at three timepoints during each observation day. Negative binomial GLMMs compared the behaviour observed during zoo closure to the behaviour observed during zoo reopening, whilst accounting for climatic variables and time of day. Spearman's correlation identified relationships between behaviour with the number of visitors and weather. Greater Flamingos were not influenced by the reintroduction of visitors to the zoo setting. Chilean Flamingos showed an increase in inactivity and decrease in movement and feeding when the zoo reopened. These possible behavioural responses are better explained by the influence of temperature on the behaviour of Chilean Flamingos and by the correlation between temperature and visitor number, rather than a direct consequence of visitor presence. This research details the multifactorial nature of any potential anthropogenic effects on zoo animal behaviour and highlights the importance of considering environmental variables alongside the measurement of visitor presence or absence.

Stress-free vet visits: considering the effects of the COVID-19 pandemic

Visits to the small animal veterinary practice are typically stressful for many animals, especially where they already have an anxious or fearful disposition. Although the purpose of the visit is to improve the animal's welfare (by improving physical health and wellbeing), there may be an impact on the animal's mental health and emotional state. The current pandemic situation has made vet visits even more difficult, because a number of options for preparing for the visit, or carrying out the visit itself, have not always been available. This article considers techniques for minimising fear, anxiety and stress in companion animals being treated at the vet practice, through preparation, protocols and procedures. Principles of good practice when helping animals to have the least stressful experience during a vet visit are considered. Additional special measures for particularly anxious or fearful animals are also discussed. The identification of stress-reducing protocols is largely based on the low-stress handling techniques identified in research and the importance of these as perceived by veterinary staff. Changes within the practice that have impacted animals' anxiety levels, as a result of the COVID-19 pandemic, are identified and considered. Reflections concerning the pandemic experience, as provided to the author by a number of veterinary surgeons and nurses, are recorded and considered as the basis for further research. Consideration is also given to the feasibility and value of retaining some changes implemented during the COVID-19 pandemic.

Changes in the haematological profile in dogs owned by owners with COVID-19

The study was performed over a period of approximately 3 months in two private clinics in Iasi, on an umber of 43 dogs of different breeds and ages whose owners were diagnosed in the last 3 months, prior to the study, with SARS CoV 2. The main change from a behavioral point of view was the change in eating habits, respectively the increase in food consumption, a fact confirmed by 86% of respondents. It was also found that there was a very significant statistical correlation between the diagnosis of relative neutrophilia and relative eosinopenia in the investigated dogs.

A Review and Categorization of Artificial Intelligence-Based Opportunities in Wildlife, Ocean and Land Conservation

The scholarly literature on the links between Artificial Intelligence and the United Nations’ Sustainable Development Goals is burgeoning as climate change and the biotic crisis leading to mass extinction of species are raising concerns across the globe. With a focus on Sustainable Development Goals 14 (Life below Water) and 15 (Life on Land), this paper explores the opportunities of Artificial Intelligence applications in various domains of wildlife, ocean and land conservation. For this purpose, we develop a conceptual framework on the basis of a comprehensive review of the literature and examples of Artificial Intelligence-based approaches to protect endangered species, monitor and predict animal behavior patterns, and track illegal or unsustainable wildlife trade. Our findings provide scholars, governments, environmental organizations, and entrepreneurs with a much-needed taxonomy and real-life examples of Artificial Intelligence opportunities for tackling the grand challenge of rapidly decreasing biological diversity, which has severe implications for global food security, nature, and humanity.

COVID 19 - induced stress in dogs owned by elderly people

The study was conducted over a period of 2 months, between March and May 2020, in collaboration with 3 private clinics in Moldova region on 23 dogs of different breeds, sex and ages, paraclinically examined by hematological and biochemical tests. The inclusion criterion in the study was the ownership of all subjects by elderly persons affected.by COVID 19 limitations during the emergency state in Romania. The study aimed to establish the correlation between the limited walking time in dogs and the level of stress induced by it. Each subject underwent 2 paraclinical check-ups in term of hematological testing and cortisol dosage at the end of March and beginning of May. Also, a control group of 13 dogs owned by active people was examined in a similar manner, both at the beginning of the experiment and also at the end of it. Compared with the initial values which were highly elevated (10,89..1,66 g/dl) in all dogs owned by elderly people, the second testing revealed values comparable to normal, but still increased (4,85..1,22 g/dl). The study demonstrates the impact of COVID 19 limitations in terms of outdoor time for dogs which produced transitional changes in cortisol levels, but also the adaptive compensatory mechanisms used to cope with modified environmental conditions.

Accuracy of Risk Perception of Zoonoses Due to Intensive Animal Farming and People’s Willingness to Change Their Animal Product Consumption

Zoonoses have become more frequent and intense. As intensive animal farming plays a role in the emergence of zoonoses, the increase in intensive animal farming increases the risk of future zoonotic outbreaks. This raises the question of to what extent people are aware that intensive animal farming poses a risk to zoonoses. Furthermore, if people would be made aware, would they be willing to take protective measures, such as reducing their animal food consumption? This was investigated in a representative descriptive study of 1009 Dutch citizens. We measured participants’ perception of the risk of intensive animal farming and their perception of the way animals are treated. We measured their willingness to consume fewer animal products and their opinions on governments banning intensive animal farms. Additionally, participants estimated the percentage of meat from intensive farms that they consume. The main results showed that most participants were aware that zoonoses can occur through intensive animal farming, but not where their meat comes from. The majority of participants were willing to change their animal consumption behavior if this could reduce future zoonotic outbreaks.

COVID-19 Restrictions in a Nature Reserve Reveal the Costs of Human Presence for the Threatened Nubian Ibex (Capra nubiana)

The increasing pressure of ecotourism on wildlife in their natural habitats leads many wild animals to alter their behaviors. The restrictions issued in many places due to COVID-19 provide a rare opportunity to examine wildlife behavior in nature reserves with reduced human presence, and to reveal the impact of human visitation on the behaviors and fitness of local wildlife species. In 2019 and 2020 we placed trail cameras next to two natural springs in the Israeli Negev Desert, Ein-Avdat and Ein-Shaviv, located 9 km apart. Both sites serve as the main water source for local Nubian ibex (Capra nubiana) populations, but Ein-Avdat is situated within a popular national park into which visitors' entrance was restricted due to COVID-19 regulations in 2020, while Ein-Shaviv is more remote and thus attracts only few visitors regardless of COVID-19 regulations. Our study revealed that during 2020, ibex in Ein-Avdat arrived to drink earlier in the day and the population's Female:Kids ratio more than doubled. These changes were not observed in Ein-Shaviv. We found that the daily number of visitors in Ein-Avdat affected the arrival time of ibex to the water pool. We conclude that the reduced number of visitors to Ein-Avdat in 2020 compared to 2019 may have allowed ibex to arrive in preferred hours, and may have contributed to the increased kid-to-females ratio. Our study shows that behavioral adaptions to human visitation in nature reserves might carry a high fitness cost.

Applying Behavioral and Physiological Measures to Assess the Relative Impact of the Prolonged COVID-19 Pandemic Closure on Two Mammal Species at the Oregon Zoo: Cheetah (A. jubatus) and Giraffe (G. c. reticulata and G. c. tippelskirchii).

The effect of visitor presence on zoo animals has been explored in numerous studies over the past two decades. However, the opportunities for observations without visitors have been very limited at most institutions. In 2020, the Oregon Zoo was closed, in response to the global SARS-CoV-2 (COVID-19) pandemic, from 15 March 2020 to 12 July 2020, resulting in approximately four consecutive months without visitor presence. This study aimed to quantify potential behavioral and hormonal changes expressed during two transition periods in zoo visitor attendance: the initial time period before and after closure in March 2020 and time before and after reopening in July 2020. Fecal glucocorticoid metabolite (fGM) concentrations of resident giraffes (n = 2) and cheetahs (n = 2) were tracked using enzyme immunoassay (EIA) analyses. Average fGM concentrations during the two transition periods were compared using a two-way mixed ANOVA. Additionally, twice-weekly scan sampling was used to quantify behavioral observations across the transitions, which were analyzed as individual behavior proportions. Individual behavior proportions were compared across the Zoo's opening status and time of day using Kruskal-Wallis (H) tests. The results of our analyses showed the following outcomes: (1) significant increases in fGM concentrations for cheetahs and giraffes between the transition periods but not within them; (2) a significant increase in time spent 'not visible' in the cheetahs in the second transition period; and (3) increased vigilance behaviors in the giraffes immediately after the Zoo's closure. However, the changes observed in fGM concentrations may be more strongly correlated with concomitant social changes (giraffes) and some medical events (cheetahs) rather than with the Zoo's opening status. Nevertheless, this study was able to quantify differences in behavioral frequencies and fGM concentration in cheetahs and giraffes at the Oregon Zoo during the times of transition between visitor's presence and absence. The results indicate that, while there was a possible, but relatively minor impact of the presence and absence of visitors on some behaviors, the differences observed in fGM concentration may have been more affected by some of the concomitant social changes and medical events that happened during the same period than by the presence or absence of visitors.
