Mammals by Sergey Semenovich Schwartz is a fascinating and in-depth study that immerses the reader in the world of mammals living in the harsh conditions of the Subarctic. This volume is the first part of a large-scale project dedicated to the adaptation of animals to extreme climatic conditions, and offers a unique look at the biological and environmental mechanisms that allow these creatures to survive and thrive in difficult natural conditions. The book will be of interest not only to specialists in the field of zoology and ecology, but also to a wide range of readers, including students, teachers, as well as everyone who is interested in nature and the animal world. If you are interested in biology, ecology, zoogeography or just want to understand more deeply how living beings adapt to the environment, this work will be a real find for you. Schwartz, with a wealth of experience and deep knowledge, creates an accessible and engaging text that not only informs but also inspires. In his book, the author examines many aspects of mammalian life, ranging from their anatomical and physiological adaptations to behavioral strategies that help them survive in low temperatures, short daylight, and limited resources. Schwartz shares the results of his many years of research, drawing parallels between different species and their ways of adapting to harsh conditions. He draws attention to unique traits, such as changes in metabolism, breeding and migration patterns, and the impact of human activity on the ecosystems of the Subarctic. The topics raised in the book go beyond purely scientific analysis. Schwartz addresses environmental and conservation issues, emphasizing the importance of conserving biodiversity in the face of global climate change. It encourages readers to think about how human actions affect fragile ecosystems and what measures need to be taken to protect them. This makes the book relevant and important in the context of contemporary environmental challenges. Schwartz's style is distinguished by clarity and accessibility, which makes complex scientific concepts understandable to a wide audience. It skillfully combines scientific data with fascinating stories about the life of animals, which allows the reader not only to learn, but also to enjoy the reading process. This approach makes his work unique and attractive to those who want to learn more about nature. Among other well-known works of Sergei Semyonovich can be distinguished his research on ecology and zoology, which also received recognition in scientific circles.
