Download or read book Biosystematics of Triticeae written by Chi Yen and published by Springer Nature. This book was released on 2022-08-13 with total page 725 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book review and rearrange the research data of Triticeae published over hundreds of years, applying a modern scientific approach. Triticeae is an important tribe in the grass family (Peaceae). It includes the major cereal crops, such as wheat, barley and rye, in addition to many valuable forage crops found in different genera, such as Elymus, Agropyron, Pasthyrostachys, and Leymus. The knowledge of appropriate Triticeae taxonomy and biosystematics will serve as genetic breeding of wheat, barley, rye and forage grass. The authors attempted to remain the truth and remove the false for deriving a more natural biosystematics of Triticeae. This book covers taxonomy, cytogenetics, and molecular phylogeny. It summarizes the biosystematics of Triticeae with comprehensive and updated data. This book is divided into five volumes (Volumes 1- 5), and includes 30 genera, 2 subgenera, 464 species, 9 subspecies, and 186 varieties in Triticeae. Volume 5 introduces nine perennial genera in Triticeae: Campeiostachys, Elymus, Pascopyrum, Lophopyrum, Trichopyrum, Hordelymus, Festucopsis, Peridictyon, and Psammopyrum. Elymus (StH), Campeiostachys (StYH), Lophopyrum (E), and Trichopyrum (ESt)are polymorphic genus. They show similar morphological characters, and it is difficult to distinguish them based merely on morphological variation. Pascopyrum (StHNsXm), Hordelymus (XoXr), Festucopsis (L), Peridictyon (Xp), and Psammopyrum (EL) are small genera, mostly monotypic genera. This book can serve as highly qualified, valuable, and convenient handbooks for audiences who are interested in Triticeae. This book also includes many illustrations, in addition to the description, to help the audience understand, morphological features of the concerned taxa, which makes the explanation more precise and obvious. It is a useful tool to understand the relationship among species in Triticeae.

Available in PDF, EPUB and Kindle. Book excerpt: Praise for the first edition— "This book is guaranteed to enrich the reader's next forest visit."—Library Journal "Pielou's book brings forest ecology to naturalists, bird lovers, hikers, cyclists, canoeists, skiers, mountaineers, and back-country campers."—Seattle Post-Intelligencer "It is E. C. Pielou's contention that evergreen forests... are taken for granted and rarely well understood. To remedy this, the distinguished biogeographer has written a book focusing on the northern evergreen forests. This is a book that many naturalists, both novice and experienced, will read with pleasure and interest."—Canadian Field-Naturalist "Pielou makes a strong, irrefutable, case for the preservation of old-growth forests and wilderness. Anyone who appreciates the outdoors should have this book and take its message to heart."—Forest Planning Canada Global warming and human-driven impacts from logging, natural gas drilling, mining of oil sands, and the development of hydropower increasingly threaten North America's northern forests. These forests are far from being a uniform environment; close inspection reveals that the conifers that thrive there—pines, larches, spruces, hemlocks, firs, Douglas-firs, arborvitaes, false-cypresses, junipers, and yews—support a varied and complex ecosystem. In The World of Northern Evergreens, the noted ecologist E. C. Pielou introduces the biology of the northern forests and provides a unique invitation to naturalists, ecologists, foresters, and everyone living in northern North America who wants to learn about this unique and threatened northern world and the species that make it their home. Through identification keys, descriptions, and life histories of the conifer tree species, the author emphasizes how different these plants are both biologically and evolutionarily from the hardwoods we also call "trees." Following this introduction to the essential conifers, the author's perceptive insights expand to include the interactions of conifers with other plants, fungi, mammals, birds, and amphibians. The second edition, enriched by new illustrations by the author of woodland features and creatures, updates the text to include new topics including mycorrhizal fungi, soil, woodlice, bats, and invasive insects such as the hemlock woolly adelgid. Emphasis is given to the very real human-driven impacts that threaten the species that live in and depend on the vital and complex forest ecosystem. Pielou provides us with a rich understanding of the northern forests in this work praised for its nontechnical presentation, scientific objectivity, and original illustrations.

Available in PDF, EPUB and Kindle. Book excerpt: Global Advances in Biogeography brings together the work of more than 30 scientific authorities on biogeography from around the world. The book focuses on spatial and temporal variation of biological assemblages in relation to landscape complexity and environmental change. Global Advances embraces four themes: biogeographic theory and tests of concepts, the regional biogeography of individual taxa, the biogeography of complex landscapes, and the deep-time evolutionary biogeography of macrotaxa. In addition, the book provides a trove of new information about unusual landscapes, the natural history of a wide array of poorly known plant and animal species, and global conservation issues. This book is well illustrated with numerous maps, graphics, and photographs, and contains much new basic biogeographical information that is not available elsewhere. It will serve as an invaluable reference for professionals and members of the public interested in global biogeography, evolution, taxonomy, and conservation.

Available in PDF, EPUB and Kindle. Book excerpt: A 2017 Choice Magazine "Outstanding Academic Title" Conifers are known to everyone as a conspicuous kind of evergreen trees or shrubs that feature prominently in gardens and parks as well as in many managed forests in the cool to cold temperate regions of the Northern Hemisphere. Numerous books have been written about them and continue to appear, mostly with a bias towards these uses in Europe and North America. This second edition, revised and updated, of A Handbook of the World's Conifers is departing from this traditional approach in that it includes all the world's 615 species of conifers, of which some 200 occur in the tropics. It gives as much information about these and the Southern Hemisphere conifers as about the better known species, drawing on research into the taxonomy, biology, ecology, distribution and uses by the author over nearly 35 years. The result is a truly encyclopedic work, a true handbook of all the world's conifers, richly illustrated by the author with his line drawings and photographs taken from the natural habitats of the species.
