Book excerpt: The ecological relationships found to exist between tick vectors and pathogens in their zootic cycle can profoundly influence patterns of transmission and disease for humans and domestic animals. This book examines the ecological parameters affecting the conservation and regulation of tick-borne zoonoses as well as the geographic and seasonal distributions of those infections. Written by an eminent authority on the subject, the book will be sought after by students and researchers in ecology, invertebrate zoology, parasitology, entomology, public health, and epidemiology.
