Download and read online Australian Seeds in PDF and EPUB This is the first complete guide to the collection, processing and storage of wild collected seed. While the main focus is on Australian seeds, the procedures and protocols described within the book are of international standard and apply to users throughout the world. The book provides a basic understanding to seed biology, evolution and morphology, and includes chapters on all aspects of harvesting, processing and storage of seeds. This will enable users to collect, process and store seed more efficiently, thus reducing loss of seed viability during the storage process with potentially huge savings in time, effort and expense in the rehabilitation and restoration industries. With a strong emphasis on the species-rich Western Australian region, Australian Seedsfeatures photographs of more than 1200 species showing clearly their size and shape. Comprehensive seed germination data enables users to know how long to allow for germination times and whether some form of pre-germination treatment is required and what this should be. This is of major importance to horticulturists and agriculturists planning crop and weed control programes. It will also be a valuable resource to anyone interested in Australian flora
Download and read online A Manual for the Identification of Plant Seeds and Fruits in PDF and EPUB The taxonomic identification of individual seeds and fruits of wild and cultivated plants is not always straightforward. The specialist literature and botanical reference collections can be helpful, and knowing where to begin reading and comparing can save a considerable amount of time. We wrote A Manual for the Identification of Plant Seeds and Fruits to make your search easier. It describes the inflorescence(s) and infructescence(s) seen in each of a set of 19 plant families, as well as the morphology of its seeds and fruits (with special emphasis on fruit typology); the dispersal units (diaspores); and, if present, heterocarpism and seed dimorphism. The manual is richly illustrated with 460 colour photos of inflorescences, infructescences, seeds, and fruits. Each entry concludes with a concise seed atlas that depicts the variation in the individual plant family's seed and fruit forms. A Manual for the Identification of Plant Seeds and Fruits includes the following plant families: Amaranthaceae Apiaceae Asteraceae Boraginaceae Brassicaceae Caryophyllaceae Convolvulaceae Cyperaceae Fabaceae Geraniaceae Juncaceae Lamiaceae Malvaceae Plantaginaceae Poaceae Polygonaceae Ranunculaceae

Download and read online Tree Identification Book in PDF and EPUB A new method for the practical identification and recognition of trees -- and an important supplement to existing botanical methods. The book is in two parts: Pictorial Keys and Master Pages. The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus. Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system. All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

Download and read online Cannabis in PDF and EPUB Cannabis sativa is best known as the source of marijuana, the world’s most widely consumed illicit recreational drug. However, the plant is also extremely useful as a source of stem fiber, edible seed oil, and medicinal compounds, all of which are undergoing extremely promising research, technological applications, and business investment. Indeed, despite its capacity for harm as a recreational drug, cannabis has phenomenal potential for providing new products to benefit society and for generating extensive employment and huge profits. Misguided policies, until recently, have prevented legitimate research on the beneficial properties of cannabis, but there is now an explosion of societal, scientific, and political support to reappraise and remove some of the barriers to usage. Unfortunately, there is also a corresponding dearth of objective analysis. Towards redressing the limitation of information, Cannabis: A Complete Guide is a comprehensive reference summarizing botanical, business, chemical, ecological, genetic, historical, horticultural, legal, and medical considerations that are critical for the wise advancement and management of cannabis in its various forms. This book documents both the risks and benefits of what is indisputably one of the world’s most important species. The conflicting claims for medicinal virtues and toxicological vices are examined, based mainly on the most recent authoritative scientific reviews. The attempt is made consistently to reflect majority scientific opinion, although many aspects of cannabis are controversial. Aside from the relevance to specialists, the general public should find the presentation attractive because of the huge interest today in marijuana. Unfortunately, society has become so specialized and compartmentalized that most people have limited appreciation of the importance of science to their lives, except when a topic like marijuana becomes sensationalized. This review of cannabis can serve as a vehicle for public education in the realm of science and technology. Indeed, towards the goal of disseminating the important information in this book to a wide audience, the presentation is user-friendly, concise, and well-illustrated in the hope that non-specialists will find the topics both informative and entertaining.

Download and read online Guns Germs and Steel The Fates of Human Societies in PDF and EPUB "Fascinating.... Lays a foundation for understanding human history."—Bill Gates In this "artful, informative, and delightful" (William H. McNeill, New York Review of Books) book, Jared Diamond convincingly argues that geographical and environmental factors shaped the modern world. Societies that had had a head start in food production advanced beyond the hunter-gatherer stage, and then developed religion --as well as nasty germs and potent weapons of war --and adventured on sea and land to conquer and decimate preliterate cultures. A major advance in our understanding of human societies, Guns, Germs, and Steel chronicles the way that the modern world came to be and stunningly dismantles racially based theories of human history. Winner of the Pulitzer Prize, the Phi Beta Kappa Award in Science, the Rhone-Poulenc Prize, and the Commonwealth club of California's Gold Medal.

Download and read online The Book of Eggs in PDF and EPUB From the brilliantly green and glossy eggs of the Elegant Crested Tinamou—said to be among the most beautiful in the world—to the small brown eggs of the house sparrow that makes its nest in a lamppost and the uniformly brown or white chickens’ eggs found by the dozen in any corner grocery, birds’ eggs have inspired countless biologists, ecologists, and ornithologists, as well as artists, from John James Audubon to the contemporary photographer Rosamond Purcell. For scientists, these vibrant vessels are the source of an array of interesting topics, from the factors responsible for egg coloration to the curious practice of “brood parasitism,” in which the eggs of cuckoos mimic those of other bird species in order to be cunningly concealed among the clutches of unsuspecting foster parents. The Book of Eggs introduces readers to eggs from six hundred species—some endangered or extinct—from around the world and housed mostly at Chicago’s Field Museum of Natural History. Organized by habitat and taxonomy, the entries include newly commissioned photographs that reproduce each egg in full color and at actual size, as well as distribution maps and drawings and descriptions of the birds and their nests where the eggs are kept warm. Birds’ eggs are some of the most colorful and variable natural products in the wild, and each entry is also accompanied by a brief description that includes evolutionary explanations for the wide variety of colors and patterns, from camouflage designed to protect against predation, to thermoregulatory adaptations, to adjustments for the circumstances of a particular habitat or season. Throughout the book are fascinating facts to pique the curiosity of binocular-toting birdwatchers and budding amateurs alike. Female mallards, for instance, invest more energy to produce larger eggs when faced with the genetic windfall of an attractive mate. Some seabirds, like the cliff-dwelling guillemot, have adapted to produce long, pointed eggs, whose uneven weight distribution prevents them from rolling off rocky ledges into the sea. A visually stunning and scientifically engaging guide to six hundred of the most intriguing eggs, from the pea-sized progeny of the smallest of hummingbirds to the eggs of the largest living bird, the ostrich, which can weigh up to five pounds, The Book of Eggs offers readers a rare, up-close look at these remarkable forms of animal life.
