Studying captive animals
Studying Captive Animals outlines the methods that may be used to study the behaviour, welfare and ecology of animals living under the control of humans, including companion animals, feral populations, and those living on farms and in zoos.
This book is a step-by-step guide to the whole process of conducting a scientific study: from designing the original project, formulating testable hypotheses, and collecting and analysing the data, to drawing conclusions from the work and writing it up as a scientific report or paper. It also illustrates how to write a formal research proposal - a crucial and often difficult element of the student project - and how to deal with the ethical review process.
Sample data collection sheets are provided and the analysis and presentation of data are worked through in diagrammatic form. In addition, exercises are included that enable the reader to practice analysing different types of data and advice is provided on the selection of appropriate statistical tests. The text describes the different types of student projects that may be undertaken in the field, and explains where secondary data may be found for zoos.
This is an insightful resource, particularly for those studying and working with zoo and farm animals. It is essential reading for students studying zoo biology and animal management; it is also suitable for students on courses in animal behaviour, animal welfare, zoology, biology, psychology, animal science, animal production, animal ecology, conservation biology, and veterinary science. This book is primarily intended for undergraduates but will also be of value to postgraduate students who have not previously engaged in field studies. Professionals working in institutions that are members of the World Association of Zoos and Aquariums, the European Association of Zoos and Aquaria and other regional and national zoo organisations will benefit from access to this practical guide.

Vegan is love : having heart and taking action
Outlines what can be done to protect animals and the environment by making such decisions as refusing products tested on or made from animals, avoiding aquariums and zoos, and choosing to buy organic food.

Zoo Conservation Biology
In the face of ever-declining biodiversity, zoos have a major role to play in species conservation. Written by professionals involved in in situ conservation and restoration projects internationally, this is a critical assessment of the contribution of zoos to species conservation through evidence amassed from a wide range of sources. The first part outlines the biodiversity context within which zoos should operate, introducing the origins and global spread of zoos and exploring animal collection composition. The second part focuses on the basic elements of keeping viable captive animal populations. It considers the consequences of captivity on animals, the genetics of captive populations and the performance of zoos in captive breeding. The final part examines ways in which zoos can make a significant difference to conservation now and in the future. Bridging the gap between pure science and applied conservation, this is an ideal resource for both conservation biologists and zoo professionals.

Wild life : the institution of nature
Wild Life documents a nuanced understanding of the wild versus captive divide in species conservation. It also documents the emerging understanding that all forms of wild nature—both in situ (on-site) and ex situ (in captivity)—may need to be managed in perpetuity. Providing a unique window into the high-stakes world of nature conservation, Irus Braverman describes the heroic efforts by conservationists to save wild life. Yet in the shadows of such dedication and persistence in saving the life of species, Wild Life also finds sacrifice and death. Such life and death stories outline the modern struggle to define what conservation should look like at a time when the long-established definitions of nature have collapsed.
Wild Life begins with the plight of a tiny endangered snail, and ends with the rehabilitation of an entire island. Interwoven between its pages are stories about golden lion tamarins in Brazil, black-footed ferrets in the American Plains, Sumatran rhinos in Indonesia, Tasmanian devils in Australia, and many more creatures both human and nonhuman. Braverman draws on interviews with more than one hundred and twenty conservation biologists, zoologists, zoo professionals, government officials, and wildlife managers to explore the various perspectives on in situ and ex situ conservation and the blurring of the lines between them.

A combined amplicon approach to nematode polyparasitism occurring in captive wild animals in southern China
Background
Gastrointestinal tract (GIT) nematodes prefer to live in the intestines of wild animals, causing damage and even death, and posing a zoonotic risk. The polyparasitism of GIT nematodes results in the complex dynamics of the nematode communities that occur naturally in wild animals. However, the nematode community in captive wild animals is poorly understood.
Methods
We combined microscopic examination and amplicon sequencing for community diversity.
Results
We characterized GIT nematode assemblages to one order, one family, four genera, and ten species, in 512 fecal samples of 121 species from captive wild animals in southern China. The positive rate of GIT nematodes was 20.7% (106/512), including 42.3% (11/26) in reptiles, 26.5% (39/147) in herbivores, 25.0% (25/100) in non-human primates, 20.0% (5/25) in omnivores, 12.2% (9/74) in carnivores, and 12.1% (17/140) in avians. The dominant nematodes were
Haemonchus contortus
in herbivores and
Trichuris
species in primates. The nematode communities of arboreal primates differed from their terrestrial counterparts, reflecting both host phylogeny and ecological constraints. Soil-transmitted
Strongyloides
species were widespread throughout the herbivore, primate, avian, and carnivore communities, and tended to infect omnivorous primates and terrestrial herbivores. In addition, new
Trichuris
and
Heterakis
species were found in the nematode communities of captive porcupines and peafowls.
Conclusion
This study highlights the variation in the composition of the GIT nematode community and strengthens the attention to the harms induced by zoonotic nematodes and co-infective nematodes with low species richness.

Genetic Structure and Diversity of Hatchery and Wild Populations of Yellow Catfish ITachysurus fulvidraco/I from Korea
Yellow catfish Tachysurus fulvidraco is an important commercial fish species in South Korea. However, due to their current declines in its distribution area and population size, it is being released from hatchery populations into wild populations. Hatchery populations also produced from wild broodstocks are used for its captive breeding. We reported 15 new microsatellite DNA markers of T. fulvidraco to identify the genetic diversity and structure of its hatchery and wild populations, providing baseline data for useful resource development strategies. The observed heterozygosity of the hatchery populations ranged from 0.816 to 0.873, and that of the wild populations ranged from 0.771 to 0.840. Their inbreeding coefficient ranged from −0.078 to 0.024. All populations experienced a bottleneck (p < 0.05), with effective population sizes ranging from 21 to infinity. Their gene structure was divided into two groups with STRUCTURE results of K = 2. It was confirmed that each hatchery population originated from a different wild population. This study provides genetic information necessary for the future development and conservation of fishery resources for T. fulvidraco.
