The book “Methodical issues of studying the primary production of plankton of inland water bodies”, created by the team of authors, is a unique study that immerses the reader in the world of aquatic ecosystems and their biological diversity. This publication will be especially interesting for those who are fond of ecology, biology, hydrobiology and environmental protection. It will become an indispensable tool for students, graduate students and researchers working in the field of water research. The book focuses on the primary production of plankton the basis of the food chain in water bodies. The authors examine in detail methodological approaches to the study of this important component of ecosystems, focusing on various research methods that provide accurate and reliable data on the state of planktonic communities. The reader will be able to learn about modern methods of collecting and analyzing samples, as well as how to correctly interpret the results. The book offers not only theoretical foundations, but also practical recommendations, making it a valuable resource for practicing scientists. The topics raised in the book cover a wide range of issues related to inland water ecosystems. The authors investigate the influence of various factors — from climatic conditions to anthropogenic influences — on the productivity of plankton. This allows for a deeper understanding of how changes in the environment can affect biodiversity and water health. In the context of global climate change and increasing human pressure, such studies are becoming especially relevant. The book “Methodical issues of studying the primary production of plankton of inland water bodies” will be of interest not only to specialists, but also to a wide audience, which seeks to understand how ecosystems function and what role microscopic organisms play in them. It can be useful for teachers who are looking for quality teaching materials for their students, as well as for environmentalists involved in the protection of water bodies and the restoration of ecosystems. The style of the authors is distinguished by scientific rigor, but at the same time the availability of the presentation, which makes the material understandable even for those who do not have deep knowledge in the field of biology. The team of authors consists of experienced scientists who have already established themselves in the scientific community thanks to their previous works. Their experience and knowledge, gathered in one edition, create a unique value for the reader. If you are looking for books that will help you better understand ecosystems and their interactions, then this edition will be a great addition to your library. It can be compared to other work in the field of ecology and hydrobiology, such as “The ecology of freshwater bodies” or “Plankton biology”, but stands out for its emphasis on methodological aspects and practical recommendations. Thus, “Methodical issues of studying the primary production of plankton of inland water bodies” is not just a book, but a whole world of knowledge that opens the door for the reader to the fascinating and important world of aquatic ecosystems. If you are interested in how ecosystems function and want to learn more about plankton and its role in nature, this book will be your reliable guide in this exciting exploration.
