Parasitology: A Conceptual Approach is a new textbook for upper-level undergraduate and graduate students which focuses on concepts and principles without neglecting important aspects of a traditional, taxonomically based approach to parasitology. Concentrating on concepts enables readers to gain a broader perspective that will increase their ability to think critically about various parasitic associations. The interfaces between the study of parasitism and prominent biological disciplines such as biodiversity, immunology, ecology, evolution, conservation biology, and disease control are highlighted. End-of-chapter questions are provided, as is an Instructor Manual.Information on individual parasites is expertly summarized in a concise appendix called the RoguesÕ Gallery. This appendix is organized taxonomically and includes details on taxonomy, life cycle, associated pathology, treatment, and control. Species included in the RoguesÕ Gallery are highlighted in red throughout the main text.
