One Line Description
Bridging foundational studies with cutting-edge innovations via DNA barcoding, computational morphology, and ecological monitoring, this comprehensive volume offers an indispensable, global framework for advancing diatom taxonomy and systematics across biological and environmental sciences, while comprising a necessary basis for all diatom studies and providing a multi-discipline approach for those in the laboratory, museum, digital, or analytical setting. The scope of the volume ranges from classical to modern diatom taxonomic treatments that compliment contemporary interest in climate science, biodiversity, and molecular biology as well as digital techniques, information science, and computational methodologies.

Audience
This book is intended for use by those in taxonomy and systematics, molecular biology, evolutionary biology, ecology, biological methods, environmental and climate sciences, museum studies, computer vision sciences, algorithm sciences, pattern recognition sciences, nanoscience, and applied engineering.

Description
Historically, diatom research has centered on taxonomy and systematics. With at least 200,000 species and over 1200 genera, the importance of diatom taxonomy cannot be overstated. All other biological disciplines rely on taxonomy as their starting point, whether the research is directed toward evolutionary, ecological, developmental, molecular, or genetic studies. Diatom taxonomic studies provide the impetus to develop advanced methods in naming new species for use in biological studies, where such methods include not only traditional descriptive methods, but also DNA barcoding, big data compilation and analysis, as well as other computational techniques.
This volume is a comprehensive survey of diatom taxonomic studies, covering historical overviews, traditional taxonomy and the establishment of new species designations, diatom collections as repositories for type material and research, applications of diatom taxonomy in ecology and ecosystem sustainability, biodiversity studies, and environmental sciences. The studies in this volume represent diatom research from all over the world for a wide range of fields, including environmental monitoring, climate science, biodiversity at the species or ecosystem level, and phylogenetics. This essential guide fosters a deep appreciation for the importance of diatom taxonomy to facilitate the understanding of our biological world.
Readers will find the volume:
• Offers a compilation of diatom taxonomic studies, exploring concepts concerning taxonomy in a traditional sense as well as applications of taxonomy for biodiversity and ecological studies;
• Illustrates the importance of diatom taxonomy through a perspective of global research importance of diatom taxonomy;
• Introduces a vast array of topics, such as the history of diatom systematics, the importance of typography, the identification of new species, and verification of taxa via checklists;
• Explores applied studies for specific environmental regions, including deserts and coastal lagoons, as well as their adaptability to extreme conditions;
• Uses analytical methods as an aid to determine the extent of morphological variability among species in a genus.
