Dictyostelids: Biology, Biogeography, Systematics, Bioactivity, and Bacterial Symbionts

This book provides a comprehensive overview of dictyostelids, the second major group of slime molds and one of the most abundant and widespread microorganisms in terrestrial ecosystems. The chapters cover a wide range of topics, including the biology, morphology, and social behavior of dictyostelids, as well as methods for isolating and culturing them in laboratory settings. Readers will gain insights into the dispersal mechanisms, biogeography, and molecular studies that have advanced our understanding of these organisms. The book also examines the symbiotic relationships that dictyostelids maintain with bacteria and other microorganisms, offering insights into their complex interactions and evolutionary significance. The book highlights the latest molecular studies that have reshaped their classification and revealed potential bioactive compounds with antibacterial and anticancer properties. Since their discovery in 1869, nearly 200 species have been identified across habitats ranging from the high Arctic to the subantarctic, with approximately 30% of these species described in this volume. Often confused with the myxomycetes, dictyostelids possess unique life cycles and distinct biological significance. The book explores their primary microhabitat-the soil and humus layer of forest floors-as well as other environments where they play vital ecological roles and serve as model organisms in studies of cell development and evolution. This book is an essential resource for researchers, scholars, and students in microbiology, ecology, and related fields. With well-illustrated content, including microscopic images, this volume offers a detailed and engaging exploration of dictyostelids, inviting readers to appreciate their complexity and significance in the natural world.
