This text, in three volumes, presents a detailed revision of the systematics and taxonomy of the platyhelminth class Trematoda, subclasses Aspidogastrea and Digenea. These parasites attack animals and humans and have a great economic impact.

The book by K. V. Galaktionov and A. A. Dobrovolskij maintains the tra- tion of monographs devoted to detailed coverage of digenetic tr matodes in the tradition of B. Dawes (1946) and T. A. Ginetsinskaya (1968). In this - spect, the book is traditional in both its form and content. In the beginning (Chapter 1), the authors provide a consistent analysis of the morphological features of all life cycle stages. Importantly, they present a detailed char- terization of sporocysts and rediae whose morphological-functional orga- zation has never been comprehensively described in modern literature. The authors not only list morphological characteristics, but also analyze the functional significance of different morphological structures and hypothesize about their evolution. Special attention is given to specific features of m- phogenesis in all stages of the trematode life cycle. On this basis, the authors provide several original suggestions about the possible origins of morp- logical evolution of the parthenogenetic (asexual) and the hermaphroditic generations. This is followed by a detailed consideration of the various m- phological-biological adaptations that ensure the successful completion of the complex life cycles of these parasites (Chapter 2). Life cycles inherent in different trematodes are subject to a special analysis (Chapter 3). The authors distinguish several basic types of life cycles and suggest an original interpretation of their evolutionary origin. Chapter 4 features the analysis of structure and the dynamics of trematode populations and is unusual for a monograph of this type.

When this historically significant volume was first published in 1968, the detailed study of the Trematoda had been neglected in Britain. Dawes' aim in this book was to make available in English information that will enable students, teachers, and research workers to identify the trematode parasites of representative animals from the European fauna.

We first discussed the possibility of organizing a symposium on helminth communities in June, 1986. At that time, we were engaged in writing a joint paper on potential structuring mechanisms in helminth communities; we disagreed on a number of issues. We felt the reason for such debate was because the discipline was in a great state of flux, with many new concepts and approaches being introduced with increasing frequency. After consider able discussion about the need, scope and the inevitable limitations of such a symposium, we decided that the time was ripe to bring other ecologists, engaged in similar research, face-to-face. There were many individuals from whom to choose; we selected those who were actively publishing on helminth communities or those who had expertise in areas which we felt were particularly appropriate. We compiled a list of potential participants, contacted them and received unanimous support to organize such a symposium. Our intent was to cover several broad areas, fully recognizing that breadth negates depth (at least with a publisher's limitation on the number of pages). We felt it important to consider patterns amongst different kinds of hosts because this is where we had disagreed among ourselves.

Canine Parasites and Parasitic Diseases offers a concise summary, including the distribution, epidemiology, lifecycle, morphology, clinical manifestations, diagnosis, prophylaxis and therapeutic measures on the most important parasites affecting dogs. The book includes their classification, structure, lifecycles, occurrence, and the diagnosis and treatment of infestations. Chapters are presented in a consistent and logical format with extensive use of tables, photographs and line drawings that help veterinarians and students quickly find answers to questions. The book informs on 100 different species of parasite related to the canine world and is is aimed not only at veterinary practitioners but also in dog enthusiasts, pharmacies and laboratories. - Fully illustrated with high-quality figures and illustrations - Provides insights on the risk factors and prevention of parasite infections in dogs and gives guidelines for anthelmintic treatment - Serves professionals, students, parasitologists and veterinary scientists - Present an easy-to-use handbook on the identification of canine parasites and the diseases associated with parasitic infection
