The book “Systematics and Biology of Freshwater Organisms of Northeast Asia”, created by the team of authors, is a unique scientific publication that immerses the reader in the richness and diversity of freshwater fauna of this mysterious region. This book is a real storehouse of knowledge for professionals, students, researchers and anyone interested in the nature and ecosystems of Northeast Asia, as well as for nature lovers seeking to understand the complex relationships in freshwater ecosystems. The book focuses on the systematics and biology of freshwater organisms living in unique water bodies of the region, such as lakes, rivers and ponds located in Russia, China, Mongolia and Korea. The authors examine in detail the diversity of species, their morphological features, ecological niches and adaptations to living conditions in fresh water, which makes the publication a valuable source for scientists involved in hydrobiology, ecology and zoology. Special attention is paid to biodiversity, its conservation and the impact of anthropogenic factors on the ecosystems of the region. The book “Systematics and Biology of Freshwater Organisms of Northeast Asia” is not only a scientific work, but also a guide to the rich world of freshwater organisms. The reader will be able to get acquainted with the diversity of fish, amphibians, molluscs, crustaceans and aquatic plants, as well as learn about their role in ecosystems, about the relationships between species and how environmental changes affect their numbers and health. The authors use modern research methods, such as molecular taxonomy and environmental monitoring, which makes the book relevant and modern-oriented. This book is especially recommended for university students and faculty specializing in biological sciences, as well as for professional ecologists and hydrobiologists working in the field of conservation of natural resources. It will also be of interest to those involved in the practical protection of nature, as it reveals important aspects of biodiversity and its vulnerability. In addition, the book can be an inspiration for those who dream of traveling to the wild corners of Northeast Asia and want to understand what species live there and how they interact with the environment. The author's team, united under the guidance of experts in the field of hydrobiology and systematics, created a work that combines scientific rigor and accessibility. The style of presentation is distinguished by clarity and logical structure, which allows even beginners in science to easily navigate the complex issues of biology of freshwater organisms. The book presents not only theoretical foundations, but also practical recommendations for the study and protection of the aquatic ecosystems of the region. Special attention is given to topical topics such as the impact of climate change, water pollution and the introduction of invasive species on biodiversity. These questions make the book particularly important in the context of the current environmental challenges facing Northeast Asia. The reader will be able to understand why the conservation of freshwater species is not only a scientific task, but also a crucial part of the global responsibility for the future of the planet.
