BOTANY VOLUME 4 - ECOLOGY - 2007

Preface to the Russian Edition

E. Strasburger's textbook "Botany", offered here to the reader's attention, was first published over 100 years ago and quickly gained recognition from the global scientific community for its fundamental nature and breadth of coverage, its original and vivid presentation, and its accessible style, eventually becoming a classic guide for many generations of researchers. Plant life in all The Diversity of its manifestations, along with The complexity of the Structural and functional interrelations that determine The Role and position of plants in the biosphere, becomes much clearer and more tangible after reading this book. Following E. Strasburger's passing, the republication of the book has been sustained by international teams of renowned scientists who, while preserving its foundational Structure, enrich it with up-to-date factual material and maintain a theoretical level appropriate to the time of publication.

This continuous updating has given the book an exceptionally long life. The present edition differs significantly from previous ones: new authors contributed to the revision of four out of the six main sections. The Introduction/27.html">Translation of the 35th edition of this original work—undoubtedly a classical compendium of botany—will be an essential and valuable resource for Russian-speaking readers studying botany as an integrative life science. It should not be viewed merely as a standard textbook; rather, it is a guide for anyone who has chosen the plant kingdom as a fascinating subject of study and wishes to acquire the most up-to-date scientific insights. This makes it invaluable for the novice botanist, the experienced naturalist-researcher, and particularly for undergraduate students, graduate students, and university faculty.

The book begins with a Description of the Structure and properties of Water and the biochemistry of plant Cell polymers (Nucleic Acids, Proteins, Polysaccharides, and Lipids). This approach is well-founded, as it provides a solid foundation for subsequent sections—cytological, morphological, and anatomical—enabling a better grasp of the principles underlying the functional Organization of both The Cell and the plant Organism as a whole. The section on Cell Structure covers the methodology of its study and presents MODERN CONCEPTS OF biochemistry, physical chemistry, membrane function, cellular compartmentalization, and the evolution of cell compartments.

A substantial portion of the book is dedicated to describing the physiological Functions of the plant organism and their underlying metabolic systems, which sustain life and enable adaptation to diverse environmental conditions. These metabolic systems interact in complex ways, and the coordination of their functions across time and space is presented from a contemporary perspective.

Metabolic reactions within the organism require significant energy inputs, driven by energy-Transduction processes that are universal across bacterial, chloroplast, and plant or mitochondrial animal Cells. In all these systems, light energy or the energy of oxidized substrates is utilized to drive electron transport across membranes, coupled with the generation of a proton gradient that ultimately powers ATP synthesis. A thorough understanding of these mechanisms requires careful Study of the respective chapters, focusing on the General Principles of Electron Transport Chain organization in coupling membranes and the characteristics of their primary components. The interactions between Mitochondria and METABOLISM/14.html">Chloroplasts play a vital role in plant life, establishing feedback and feedforward loops crucial for maintaining The Cell as an integrated functional unit that can flexibly adjust its Respiration rate in response to various endogenous and exogenous factors. A fundamental task in understanding plant life processes is exploring modern concepts of Photosynthesis AS THE physiological function that forms the core of Bioenergetics. The foundational processes of photosynthesis—the structural and functional ORGANIZATION OF THE photosynthetic apparatus, the Molecular structure and PHYSICOCHEMICAL PROPERTIES OF pigment systems, the mechanisms of primary energy-conversion processes, and the Structure and function of reaction centers—have been re-investigated in recent years, and these updates are fully reflected in the relevant chapters.

As Key Components of the biosphere, plants perform immense geochemical work driven primarily by their modes of mineral Nutrition and water relations. In recent years, our understanding of ion and water uptake in plants has evolved significantly, alongside a marked expansion of knowledge regarding the functions of mineral nutrients. The book covers a wealth of material on the mechanisms of ion and water entry into the apoplast, membrane transport systems, short- and long-distance Transport of substances, and their internal Circulation within the plant, providing a clear picture of how these processes contribute to a functionally integrated whole.

Plant GROWTH AND DEVELOPMENT are integrative physiological functions through which the genetic potential of the organism unfolds, securing the adaptive and reproductive potential of the species. Studying the principles of hormonal, light, thermal, and Other forms of regulation in Plant Growth and development constitutes a vital branch of botany. A plant's life unfolds in constant interaction with both abiotic (Physical and Chemical) and biotic (other plants, animals, and microorganisms) environmental factors. These interactions can significantly modify plant development and reproductive potential. The Structure of Plant communities is likewise subject to change under the profound influence of abiotic and biotic stressors. Evolution has forged numerous mechanisms that enable plants to overcome adverse conditions while preserving their potential for reproduction and dispersal. The impact of each stress factor is analyzed both in terms of its damaging effects and through the lens of the plant's active responses aimed at developing adaptive mechanisms to withstand or evade unfavorable conditions.

Beyond its text, a definitive strength of the book is its extensive use of diagrams, tables, and diverse illustrations: drawings, high-resolution micrographs, maps, and photographs of landscape vegetation. Notably, the "Ecology" section has been substantially expanded to include all essential modern insights into Earth's plant cover, alongside plant Taxonomy reorganized to reflect the latest molecular-genetic research on Phylogenetic relationships among taxa. The approaches developed by botanists in recent years have greatly advanced our understanding of plant organisms and plant communities as integrated biological systems. This is vividly reflected in the book and will undoubtedly captivate a wide readership.

In the wild, plants exist in states of competition and partnership with other organisms, constantly responding to the multifaceted influences of climate and soil. The resulting communities and ecosystems reflect these interactions. Complex environmental conditions give rise to diverse plant communities, such as those found in the montane belt of the northern Alpine foothills near Engelberg, Switzerland (1,200 m). Within a compact area, mountain forests, bogs, tall-herb communities, snow patches, rocky vegetation, stream-bank meadows, and human-molded cultural landscapes converge. Beech is one of the most prominent forest-forming tree species in Europe (the foreground shows a beech twig with insect galls; see Fig. 9.1), transitioning in this zone into mountain maple and Norway spruce.
