AbstractAnimal gut mycobiota, the community of fungi that reside within the gastrointestinal tract, make an important contribution to host health. Accordingly, there is an emerging interest to quantify the gut mycobiota of wild animals. However, many studies of wild animal gut mycobiota do not distinguish between the fungi that likely can reside within animal gastrointestinal tracts from the fungal taxa that are non-residents, such as macrofungi, lichens or plant symbionts/pathogens that can be ingested as part of the host’s diet. Confounding the non-resident and resident gut fungi may obscure attempts to identify processes associated with the authentic, resident gut mycobiota per se. To redress this problem, we propose some strategies to filter the taxa identified within an apparent gut mycobiota based on an assessment of host ecology and fungal traits. Consideration of the different sources and roles of fungi present within the gastrointestinal tract should facilitate a more precise understanding of the causes and consequences of variation in wild animal gut mycobiota composition.

Probiotics are viable microorganisms widely used for their claimed beneficial effects on the host health. A wide number of researchers proved that the intake of probiotic bacteria has numerous health benefits which created a big market of probiotic foods worldwide. The biggest challenge in the development of these products is to maintain the viability of bacterial cells during the storage of the product as well as throughout the gastrointestinal tract transit after consumption, so that the claimed health benefits can be delivered to the consumer. Different approaches have been proposed for increasing the resistance of these sensitive microorganisms, including the selection of resistant strains, incorporation of micronutrients, and most recently the use of microencapsulation techniques. Microencapsulation has resulted in enhancing the viability of these microorganisms which allows its wide use in the food industry. In this review, the most common techniques used for microencapsulation of probiotics will be presented, as well as the most usual microcapsule shell materials.

In China, the wild animals and animal products that are sold through illegal trafficking are mainly those that can be made into medicines; are raw materials in the form of ivory, rhinoceros horns, and turtle shells; and are edible or have ornamental value, such as birds, monkeys, turtles, and lizards. Due to its rapid economic development over the past decade, China has become one of the world's largest wildlife markets. The main reasons for trafficking are a lack of viable substitutes for raw materials used in traditional Chinese medicines (e.g., bear bile, bear bile powder, pangolin, and other products); a preference in traditional food culture for delicacies made from wildlife; and of the private consumption by some rich and corrupt government officials of tiger's meat, bear's paw, pangolin and other wild animal products—bear's paw and pangolin being the most popular. This type of wild animal trafficking endangers the safety of animal species protected by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), and damages the international image of the government and people of China. Since 2013, under the frame of construction of ecological civilization, China has taken stricter measures on legislation, administrative enforcement, judicial adjudication, and international cooperation on prevention and punishment of illegal trafficking.

Animal lawyers in Australia and around the world often struggle to find room in law to participate in decision-making and give animals a voice. Collaborative governance is a regulatory mechanism that has the potential to overcome this struggle. This ‘new governance’ is of growing importance in environmental and natural resource management, premised on decentralised decision-making and removal of permanent hierarchies. This article will utilise two case studies to outline the benefits of legally integrated collaborative processes for wild animal welfare, including the allocation of a permanent voice in regulation for animal advocates and the ability to promote internalisation of animal-friendly norms.

The use of wild animals as photo props is prevalent across the globe and is widely recognised to represent a potential animal welfare concern. However, detailed information regarding the specific impacts of such activity on wild animal behaviour is currently lacking. Herein, we investigated how brown-throated three-toed sloths (Bradypus variegatus) were handled by tourists, and how sloths behaved during wildlife ‘selfies’ taken in Manaus, Brazil and Puerto Alegria and Iquitos in Peru. In total, we observed 17 sloths (during 70 focal observations) that were provided for use in wildlife selfies on 34 different tours. We found that an average number of 5 people held each sloth during each focal observation. For 48.6% of the time the sloths were handled in a way which involved physical manipulation of the sloths’ head and/or limbs and/or being held by the claws. From the eight different types of sloth behaviour observed, we found that the two types performed for the longest average duration of time were surveillance (55.3%) and limb stretching (12.6%). Our findings show that when being handled sloths were frequently held in ways that may compromise their welfare. Although to date the behaviour of sloths while being handled has not been reported in any published literature, in this study we document certain behaviours which may act as indicators of compromised welfare. We suggest that our data provides a potential baseline for future study into the behaviour and welfare of sloths.

Abstract The illegal poisoning of dogs and other domestic and wild animals presents a worldwide problem causing animal suffering and R. Macedonia is not an exeption. The goal of this study is to make a comparison of the results from the histopathological examination conducted among poisoned dogs in the Republic of Macedonia. Morphological and histopathological changes in poisoned dogs were investigated for a period of 10 years. The examination was performed on 31 dogs, 13 of which were home kept, 7 were street dogs and 11 of unknown origin. The most significant necropsy findings concerned the inflammatory and necrotic processes of the gastrointestinal tract. The histopathological changes were mainly located in the kidneys, stomach, intestines and the lungs.

The gut microbiota can have important, wide-ranging effects on its host. To date, laboratory animals, particularly mice, have been the major study system for microbiota research. It is now becoming increasingly clear that laboratory animals often poorly model aspects of the biology of wild animals, and this concern extends to the study of the gut microbiota. Here, the relatively few studies of the microbiota of wild rodents are reviewed, including a critical assessment of how the gut microbiota differs between laboratory and wild rodents. Finally, the many potential advantages and opportunities of wild-animal systems for research into the gut microbiota are considered.

Insight Into

We provide an initial insight into the occurrence and characteristics of animal-visitor interactions (AVIs) involving captive wild animals within zoos and aquaria. Using information provided online via official public websites of modern zoos and aquaria, we found that AVIs were provided by the majority of facilities. Our study revealed that a variety of AVI types were being offered. Globally, petting captive wild animals was the most prevalent AVI type advertised (n = 1241 observations, 43% (534) of facilities) and Mammalia was the most advertised taxonomic class (n = 5142; 53% (2739)). We found certain AVI types that were more commonly offered than predicted. These were opportunities to: (1) Hand feed captive wild animals in Asia, North America and Oceania; (2) ride wild animals in Europe and North America; (3) walk with or swim through wild animal enclosures in Asia; and (4) walk with wild animals in Asia and Europe. Given the global prevalence of AVIs in modern zoos and aquaria, and an apparent lack of animal welfare focused research, we provide recommendations to help effectively balance and manage captive wild animal welfare with other primary interconnected goals.

Submission of learning materials with animal themes, especially wild animals to early childhood becomes a challenge for teachers. Two-dimensional displacement media in the form of a monotonous image has the potential to decrease interest in children's learning. Bringing wild animals directly or bringing the children to the zoo requires considerable cost and time and harm. Based on these problems, the authors develop android-based applications that contain fourteen species of wild animals in 3D format that is packed with Virtual Reality (VR) technology. The authors develop applications using development research methods with the ADDIE model. The developed VR application is capable of displaying wild animal animations complete with the sounds and environment of the habitat, as well as the description narrative features and food that can be viewed in 3D and VR modes. The test results showed that the application received a positive response from users, especially children in TK Negeri Pembina Singaraja. The average percentage for the user response test is 88.50%, which means it is very good where children can know the types of wild animals, the movements of wild animals, the sounds of wild animals, the habitats of wild animals and can use them easily.

In this paper, I consider whether we should offer assistance to both wild and domesticated animals when they are suffering. I argue that we may have different obligations to assist wild and domesticated animals because they have different morally-relevant relationships with us. I explain how different approaches to animal ethics, which, for simplicity, I call capacity-oriented and context-oriented, address questions about animal assistance differently. I then defend a broadly context-oriented approach, on which we have special obligations to assist animals that we have made vulnerable to or dependent on us. This means that we should normally help suffering domesticated animals, but that we lack general obligations to assist wild animals, since we are not responsible for their vulnerability. However, we may have special obligations to help wild animals where we have made them vulnerable to or dependent on us (by habitat destruction or by captivity, for instance). I consider some obvious difficulties with this context-oriented approach, and I conclude by looking more closely at the question whether we should intervene, if we could do so successfully, to reduce wild animal suffering by reducing predation.

ABSTRACT Heightened concerns about wildlife on produce farms and possible introduction of pathogens to the food supply have resulted in required actions following intrusion events. The purpose of this study was to evaluate the survival of Salmonella in feces from cattle and various wild animals (feral pigs, waterfowl, deer, and raccoons) in California, Delaware, Florida, and Ohio. Feces were inoculated with rifampin-resistant Salmonella enterica cocktails that included six serotypes: Typhimurium, Montevideo, Anatum, Javiana, Braenderup, and Newport (104 to 106 CFU/g). Fecal samples were stored at ambient temperature. Populations were enumerated for up to 1 year (364 days) by spread plating onto tryptic soy agar supplemented with rifampin. When no colonies were detected, samples were enriched. Colonies were banked on various sampling days based on availability of serotyping in each state. During the 364-day storage period, Salmonella populations decreased to ≤2.0 log CFU/g by day 84 in pig, waterfowl, and raccoon feces from all states. Salmonella populations in cattle and deer feces were 3.3 to 6.1 log CFU/g on day 336 or 364; however, in Ohio Salmonella was not detected after 120 days. Salmonella serotypes Anatum, Braenderup, and Javiana were the predominant serotypes throughout the storage period in all animal feces and states. Determination of appropriate risk mitigation strategies following animal intrusions can improve our understanding of pathogen survival in animal feces. HIGHLIGHTS
