Dr. Valerie Behan-Pelletier is an Honorary Research Associate (an Emeritus position) with the Research Branch of Agriculture and Agri-Food Canada, the federal department responsible for maintaining the national collections of insects, arachnids, nematodes, fungi and vascular plants. As a global specialist in the taxonomy and ecology of Oribatida for over 45 years, she has published a number of large monographs on oribatid mites for North America and has contributed to multi-chapter works on biodiversity, soil ecology, and ecological assessments. She is a Section Editor of the 2012 Oxford University Press publication Soil Ecology and Ecosystem Services, is a coeditor of the Global Soil Biodiversity Atlas (2016) and is coauthor of a chapter on Aquatic Oribatida in Thorp and Covich's (2016) Freshwater Invertebrates (4th ed.), Vol. II: Keys to Nearctic Fauna, Elsevier. She has published over 150 research papers. She is a past Scientific Editor of Memoirs of the Entomological Society of Canada, former Secretary of the International Congress of Acarology, and Fellow of the Entomological Society of Canada. Dr. Zoë Lindo is Full Professor, Department of Biology, Western University, London, Ontario. They are an expert in forest soil biodiversity and ecosystem function. Zoë has worked extensively in Canadian forests including the mixed-wood boreal of Alberta, the subarctic taiga of Quebec, the coastal temperate rainforest of British Columbia, and the black spruce / peatlands of Ontario. As a specialist in the ecology of soil invertebrates and the taxonomy and ecology of Oribatida for 25 years, their research focusses on ecosystems that are currently undergoing dramatic changes in biodiversity due to habitat loss and fragmentation associated with land use change, pollution, overexploitation, and climate change. They have published over 75 research papers and was recently a lead author for the UN-FAO Report on the State of Knowledge of Soil Biodiversity: Status, Challenges and Potentialities (Dec. 2020). They are a member of the Global Soil Biodiversity Initiative, the Biological Survey of Canada and is Editor-in-Chief of Pedobiologia-Journal of Soil Ecology.

It is said that each step one takes in any natural habitat is being supported by thousands of tiny legs of soil-dwelling arthropods. A major portion of these belong to oribatid mites, yet North American biologists never have had a resource that could take them from zero knowledge to species identification. Now they do – but this book is far more than an identification guide to an underappreciated group of diverse and fascinating animals. The experienced and knowledgeable authors introduce well-referenced topics that show how oribatid mites can help us address a vast range of biological, ecological and biogeographical questions.-- Roy A. Norton, Emeritus Professor and acarologist, State University of New York, College of Environmental Science and Forestry, USAThis book is an amazing work – impeccably arranged, both methodologically and in terms of content. It supplies a highly reliable and interesting collection of data on the taxonomy, ecology and geographic distribution of oribatid mites in all ecosystems of Canadian and Alaskan landscapes. The authors present an original interpretation of the high diversity, ecological importance, and natural causes of occurrence of these mites across many different ecosystems throughout the world. This book is unrivalled in the worldwide scientific literature in its field, and it will certainly meet with major interest, both in and outside Canada.-- Wojciech Niedbała, Emeritus Professor, Department of Animal Taxonomy and Ecology, Adam Mickiewicz University, PolandThis is a book I wish I had had available when I started working on oribatid mites. It is unique in providing a comprehensive compendium of all aspects of acarine biology, making it an ideal introduction that will serve as a treasured reference book for a long time, fostering a holistic understanding of these fascinating, but often understudied organisms. Bringing all these informations on form, function, phylogeny and distribution together in one comprehensible and concise collection will no doubt incite the widened interest and collaborative research the oribatida deserve. Many thanks to all authors for undertaking the effort to provide us with this invaluable resource.-- Paavo Bergmann, Department of Biology, Konstanz University, Germany
