Paperback. Condición: Very Good. The Hawaiian Islands are the most isolated archipelago on Earth. The chance arrival of plants and animals to these rich volcanic islands resulted in the evolution of a host of unique speciesalmost 90 percent of the plants native to this island chain do not occur anywhere else in the world.
 But the Hawaiian Islands were not to remain as they were. They were discovered by humans, and with the settlers came other invaders. Native species, which had evolved with few natural enemies, had little or no protection. The invasion had begun.
 The losses suffered have been huge, and until recently, few understood how much was being lost as these biological riches vanished from the Pacific Basin.
 Focusing on plants endemic to the Hawaiian Islands, Hawaii's Native Plants also includes a sampling of species that occur elsewhere in the Pacific Basin, as well as those brought by early settlers, and other alien species. Dr. Bohm begins with the basic questions island biologists ask: Where is everything? How did it all get here? When did it all happen?
 The reader will also learn of the islands' fascinating geological history and the development of its native flowering plants and ferns, and the pests that have wreaked or threatened havoc on island biodiversity and others whose impact remains to be seen. The concept of endemism, or nativeness, is also discussed. The scope of the discussion is invaluable in answering the question of what can we do now to protect what remains of Hawaii's priceless natural heritage.…

Boards show regular shelfwear, small indentations, a touch of scuffing. Issued without a dust jacket. -- The book provides an exhaustive analysis of flavonoids' role in determining relationships among plant groups, specifically within Asteraceae, the largest family of flowering plants. This monograph compiles over 2,500 reports of flavonoid studies published from 1950 onwards and interprets these findings against the backdrop of modern taxonomic alignments. The book synthesizes data from phylogenetic studies based on both morphological and DNA data, offering insights into the systematic and evolutionary relevance of flavonoids within this diverse plant family. The text outlines flavonoid patterns across various tribes of Asteraceae, such as Anthemideae, Astereae, Eupatorieae, and others, demonstrating how these compounds act as taxonomic markers at different hierarchical levels - subfamilial, tribal, subtribal, and specific. Additionally, the authors delve into the biosynthesis of flavonoids, their biological functions, and how they indicate evolutionary processes like hybridization and introgression. The work also addresses flavonoid relationships with other plant families and provides a robust evaluation of how flavonoid systems have evolved in the Asteraceae family. This publication serves as the most comprehensive reference on the systematic and evolutionary importance of flavonoids within any large family of angiosperms. It is an essential resource for botanists, plant taxonomists, chemists, and evolutionary biologists interested in plant systematics and phylogeny. -- "Flavonoids are secondary plant products that have previously been shown to be helpful in determining relationships among plant groups. This work presents comprehensively the occurrence, patterns of variation, and systematic and evolutionary importance of flavonoids in the sunflower family (Asteraceae), the largest family of flowering plants (23,000 species). It gathers together the more than 2500 reports of flavonoids in Asteraceae published between 1950 to the present and interprets these data in context of new taxonomic (especially generic) alignments. The authors discuss flavonoid patterns with reference to modern phylogenetic studies based on morphology and DNA data. This book provides, therefore, the most exhaustive synthesis and evaluation of the systematic and evolutionary import of flavonoids ever accomplished for any large family of angiosperms.".…

Taschenbuch. Condición: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book provides an overview of geographic patterns in the distribution of plant secondary metabolites in natural populations. Examples include most common natural product classes: acetylenic derivatives; alkaloids; carotenoids; cyanogenic glycosides; flavonoids; terpenes of various sizes; as well as other structural types less easily categorized. By comparison, earlier reports in the literature on 'chemical races' focused either on individual classes of compounds, on specific taxa, or on a particular geographic region.Following an introduction that includes definitions of phytochemical and biogeographic ideas, information is presented in five loosely defined geographic trans-oceanic categories: examples within continents; after the ice; intercontinental disjunctions; oceanic islands; and polar disjunctions.It has often been said that natural variation is the essence of evolution. It seems reasonable to suggest that this is as true with plant secondary metabolites as with any other feature that confers an advantage to one set of individuals over antiherbivore or antifungal activity of plants as they colonize new habitats, and thus meet new challenges; or subtle changes in floral pigmentation and patterning that would affect behavior of pollinators. …
