Furry and wide-eyed, lorises and pottos are small, nocturnal primates inhabiting African, Asian and Southeast Asian tropical and subtropical forests. Their likeable appearance, combined with their unusual adaptations – from a marked reduction of the tail to their mostly slow, deliberate locomotion, powerful grasping and, in some species, a venomous bite – has led to a significant rise in research interest in the family Lorisidae over the last decade. Furthermore, lorises in particular have featured frequently in international media largely due to illegal trade, for example as pets. This is the first volume to present a full picture of the breadth of research being undertaken on lorisids to aid future studies as well as conservation efforts. Focusing on five key topics: evolutionary biology, ecomorphology, behavioural ecology, captive management and conservation, Evolution, Ecology and Conservation of Lorises and Pottos is a vital read for graduate students and researchers in primatology, biological anthropology, evolutionary biology, animal behaviour and conservation.

K.A.I. Nekaris is Professor of Biological Anthropology at Oxford Brookes University, Oxford, UK, where she directs the Nocturnal Primate Research Group and the MSc Primate Conservation. She has conducted fieldwork on lorisids since 1993, and is Director of the Little Fireface Project, using conservation education, ecology and advocacy to conserve nocturnal mammals.
Anne M. Burrows is Professor of Anatomy at Duquesne University, Pittsburgh, Pennsylvania, USA. She has been working on evolutionary morphology of lorises and pottos for 20 years, focusing on feeding mechanisms and communication. She is co-editor of The Evolution of Exudativory in Primates (Springer, 2010) and co-author of Primate Communication: A Multimodal Approach (Cambridge University Press, 2013).
"As is made abundantly clear in this volume, and I know well from my own experience, nocturnal primates are never easy to study in the wild; in addition, pottos and lorises are rarely kept in captivity. Nevertheless, the editors have managed to gather together an impressive array of work from over 70 authors, covering a large number of topics ranging from the fossil record of these species to their conservation, through morphology, ecology, trade and many other subjects. In spite of all the information in this book, it also illustrates how much more research is needed on individual species in different field sites to ensure the conservation of these small, elusive, but fascinating, nocturnal creatures."
