Book Description
International Series of Monographs in Pure and Applied Biology, Volume 9: The Vegetation of Poland focuses on the plant geography of Poland, including climate, hydrography, geology, and ecology. The selection first offers information on the historical outline of the development of plant geography and the factors affecting the geographical distribution of plants in Poland. Discussions focus on the development of phytogeographical cartography, floristic and ecological plant geography, and the climate, boundaries, land-relief, hydrography, and geology of Poland. The text then ponders on the influence of man and his economic activities on the vegetation of Poland and the floristic statistics and the elements of the Polish flora. The publication examines the terrestrial and fresh-water plant communities and vegetation of the Polish Baltic. Topics include composition and structure of plant communities and methods of their study, associations of coastal and inland dunes, aquatic and swamp associations, and the most important representatives of the benthic flora of the Polish Baltic. The manuscript is a dependable source of data for botanists and those concerned with the plant resources of nature, including agriculturists, horticulturists, and soil scientists.

Book Description
International Series of Monographs on Pure and Applied Biology: The Plant Cell Wall, Volume 2 is a four-chapter text that covers the botanical aspects of cell wall. This book specifically discusses the cell types and cell walls in vascular plants, as well as the classification and constitution of cell wall. This book deals first with the fractionation, biosynthesis, components, formation regulation, and breakdown of cell wall. These topics are followed by discussions on cell wall polysaccharides, lignin structures, cell wall changes during cell growth, and the analysis of the wall-lysing enzymes. Other chapters examine the types and chemical components of cell wall carbohydrates and the surface processes in lignin polymer formations. A study of the phylogenetic aspects of lignins and lignin synthesis is presented. A chapter is devoted to the classification and features of plant species. The remaining chapter focuses on the non-vascular plants, protista, and metazoa. The book can provide useful information to scientists, botanists, students, and researchers.

Book Description
Mineral Salts Absorption in Plants details the contemporary knowledge regarding the mineral salt absorption mechanisms of plants. The title first covers the history of mineral salt absorption in plants, and then proceeds to tackling the experimental materials and methods. Next, the selection discusses the mechanisms of ion transport. Chapter 4 deals with the factors affecting salt absorption, while Chapter 5 talks about salt absorption and metabolisms. In the sixth chapter, the text covers the structural aspects of salt absorption in cells. The seventh chapter discusses the salts relations of vascular plants. The selection also talks about the soil as a source of mineral salts, along with salt tolerance. The book will be of great use to botanists and horticulturists. Students and researchers in the field of mineral nutrition will also benefit from the text.

Book Description
International Series of Monographs on Pure and Applied Biology, Volume 8: Short Guide to Geo-Botanical Surveying focuses on the guide used in the geo-botanical surveying of pastures, bogs, and forests. The book first offers information on geo-botanical maps and plans and geo-botanical surveys. Discussions focus on the general features of geo-botanical maps and plans, classification of geo-botanical maps, transect surveys, auxiliary methods of investigation in geo-botanical surveys, and aero geo- botanical surveys. The text then examines geo-botanical surveys for forestry needs, including survey work in forest valuation, forest-typology surveys, and notes on interpretation of aerial photographs of forest vegetation. The publication ponders on geo-botanical surveys for the needs of the peat industry and agricultural reclamation of bogs and geo-botanical surveys for study of pastures. Topics include geo-botanical survey of bogs in connection with their agricultural reclamation; general information on geo-botanical surveys in bogs; features of surveys in semi-deserts and deserts; and features of surveys on the tundra. The text is a valuable source of data for readers interested in geo-botanical surveying.

Book Description
Pure and Applied Biology, Volume 3: Physical Properties of the Steroid Hormones illustrates the efficiency of methodology for the solution of problems of isolation, identification and quantitative determination of the physical properties of steroids. This volume is composed of five chapters, and begins with a survey of the factors that influence the partition coefficient of steroid hormone, along with the consideration of the types and preparation of solvent systems for determination. The next chapter describes the chromatographic mobilities of steroids using several chromatographic methods, such as paper chromatography. A chapter presents the ultraviolet absorption data on structural correlations of steroids. Another chapter highlights the conversion of a steroid into a fluorescent compound through the steroid-acid interaction mechanism. The final chapter deals with the selective absorption spectra of steroids in concentrated sulfuric acid without heating. This book is directed primarily toward steroid chemists and researchers.
