"This book is an impressive collection of facts and ideas neatly packed into quite condensed texts. It is a breath-taking demonstration of the power of modern biology. Some elements of the global ‘Pristionchus pacificus’ project are still in the reach for even modestly equipped laboratories. Thus, the ‘La Réunion case’ is a good example of how the study of intra-specific groups of nematodes can reveal a complicated history of colonisations and adaptation. Such books serve as special messengers for the scientific community, provoking thought for further research."Sergei E. Spiridonov (Center of Parasitology, A.N. Severtsov Institute of Ecology and Evolution RAS, Moscow) in: Russian Journal of Nematology."This monograph provides an excellent, thorough and up-to-date overview of research on the diplogastrid nematode Pristionchus pacificus. From small beginnings, work on Pristionchus has expanded by now to generate dozens of significant papers each year, in varied areas of biology. It is therefore very timely to review what has been achieved, and to lay out the stall for yet more research on P. pacificus".Jonathan Hodgkin in: Nematology, Volume 17, Issue 10 (2015).
