Download or read book Toxins and Targets written by Dianne Watters and published by Taylor & Francis. This book was released on 2022-11-12 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: First Published in 1992. The last decade of the twentieth century has seen an unprecedented advocacy for the preservation of a safe environment, and the prevention of ill-health from toxic chemicals. Human activity, however, is responsible for introducing new toxins into the environment. In order to control competitors for human food sources, an armament of pesticides has been assembled and their widespread and largely uncontrolled application has been permitted. It is only when the health of the population begins to suffer from the effects of these chemicals that the efficacy of their use is questioned. Decision-makers whose roles involve the promotion and control of the environment must look to lessons that can be learnt from biosystems that include animals other than man. Toxins and Targets details the way in which organisms from diverse habitats in the plant and animal kingdoms have adapted to handle toxins safely. Part I, on the aquatic environment, highlights the means by which marine organisms have adapted their toxins to be effective in a world of high aqueous solubility and infinite dilution. Part II deals with venomous terrestrial organisms and the mechanisms by which they damage animal cells, and Part III considers the way in which human society attempts to investigate toxicity and to control both synthetic and naturally occurring poisons. The development of a safe environment depends on increased knowledge and novel approaches to solving escalating problems. This book is a step towards this end.
Download or read book Cycads written by John Sydney Donaldson and published by World Conservation Union. This book was released on 2003 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IUCN/SSC Cycad ACtion Plan brings together the best available information on this ancient and fascinating group of plants. Cycads were a dominant part of the earth's flora during the age of the dinosaurs and many species were common even in more recent times. However, many of the 297 species and subspecies dealt with in the Cycad Action Plan have been badly affected by habitat destruction and plant collecting within the last century. As a result, more than half the known species are now classified as threatened, and the cycads stand out as one of the most threatened groups of plants in this world.The Action Plan provides an overview of all the cycads and the threats to their survival. This is followed by separate assessments for the four broad regions where cycads now occur, namely Africa and the Indian Ocean Islands, Australia, Asia, and the New World. Trade in cycads has had a substantial impact on wild cycad populations and there is a separate chapter on trade and the effectiveness of control measures such as CITES. In addition, with so many species facing extinction in the wild, garden collections have become increasingly important and we have assessed the global status of cycad collections.Finally, the Cycad Action Plan presents a set of objectives and actions to reduce the threat to cycads in the wild and to provide ex situ conservation for those that almost certainly will become extinct in the wild. Wherever possible, we have tried to identify and build on innovative projects, such as community-based nurseries, and to link cycad consideration with other global and local initiatives such as the conservation of biodiversity hotspots.
Download or read book History of the Australian Vegetation written by Robert S. Hill and published by University of Adelaide Press. This book was released on 2017-03-01 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Australian vegetation is the end result of a remarkable history of climate change, latitudinal change, continental isolation, soil evolution, interaction with an evolving fauna, fire and most recently human impact. This book presents a detailed synopsis of the critical events that led to the evolution of the unique Australian flora and the wide variety of vegetational types contained within it. The first part of the book details the past continental relationships of Australia, its palaeoclimate, fauna and the evolution of its landforms since the rise to dominance of the angiosperms at the beginning of the Cretaceous period. A detailed summary of the palaeobotanical record is then presented. The palynological record gives an overview of the vegetation and the distribution of important taxa within it, while the complementary macrofossil record is used to trace the evolution of critical taxa. This book will interest graduate students and researchers interested in the evolution of the flora of this fascinating continent.

Download or read book CRC World Dictionary of Palms written by Umberto Quattrocchi and published by CRC Press. This book was released on 2017-08-03 with total page 3591 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the Foreword Umberto Quattrocchi has brought us some amazing and useful works through the various dictionaries that he has compiled. This time it is for two very important plant families the palms and the cycads that are synthesized here in these two volumes. Each entry is fascinating not just for the botany and full nomenclature of the plant species but for all the associated uses, folklore and interactions with other organisms. ...These entries are fascinating glimpses of natural history. ... Botanists, conservationists, ethnobotanists, anthropologists, geographers, bird watchers, naturalists, historians and those of many other disciplines will find these volumes a most valuable and useful resource. It is the sort of book that will be in frequent use in my library. ----- Professor Sir Ghillean Prance FRS, VMH, Former Director, Royal Botanic Gardens, Kew Following the same format as Umberto Quattrocchi’s highly praised and well-used previous works, The CRC World Dictionary of Palms: Common Names, Scientific Names, Eponyms, Synonyms, and Etymology brings together the vast and scattered literature on palms and cycads to provide better access to information on these economically important plants. Each genus and species has a detailed morphological description and includes a list of synonyms and vernacular names in many languages. Bibliographies accompany each entry which are comprehensive, up-to-date and multi-lingual. The detailed information for every entry on habitats, economic uses, historical and biographical data, botanical exploration, and linguistics will be useful for any library involved with botany, herbal medicine, pharmacognosy, medicinal and natural product chemistry, ecology, ethnobotany, systematics, general plant science, agriculture or horticulture. Umberto Quattrocchi is the author of the bestselling CRC World Dictionary of Plant Names, winner of the prestigious Hanbury Botanical Garden Award. His most recent multi-volume work, CRC World Dictionary of Medicinal and Poisonous Plants, received strong praise as being "... an unparalleled starting place—a tool of first resort for any thoughtful researcher. Quattrocchi and CRC have delivered a dictionary like no other, a learned finger pointing in the right direction." —John de la Parra, Northeastern University, Boston, Massachusetts, USA, from Economic Botany, Vol. 68, 2014
Download or read book The Book of Seeds written by Paul Smith and published by University of Chicago Press. This book was released on 2018-04-06 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Deftly showcases 600 unique species from across the globe and reveals the wonders of nature. . . . Recommended.” —Library Journal Seeds are nature’s consummate survivors. The next time you admire a field of waving green grassland or a stunning grove of acacia, stop to consider how it got that way—often against incredible odds. Seeds can survive freezing temperatures and drought. They can pass through our digestive systems without damage and weather a trip across the ocean, hitching a ride on marine debris. The Book of Seeds takes readers through six hundred of the world’s seed species, revealing their extraordinary beauty and rich diversity. Each page pairs a beautifully composed photo of a seed—life-size, and, in some cases, enlarged to display fine detail—with a short description, a map showing distribution, and information on conservation status. The whole spectrum of seeds is covered here. There are prolific species like corn and less widely distributed species, like the brilliant blue seeds of the traveler’s palm or the bird of paradise flower. There are tiny seeds and seeds weighing up to forty pounds. And while seeds in all their shapes, sizes, and colors grant us sustenance, there are even some we would be wise to treat with caution, such as the rosary pea, whose seeds are considered toxic. The essential guide to these complex plant creations, The Book of Seeds offers readers a rare, up-close look that will inspire scientists and nature lovers alike. “Handsome and handy.” —New York Times “A well-written primer on seed anatomy, evolution, and use, including conservation.” —Huntia

Download or read book Cyanobacteria in Symbiosis written by A.N. Rai and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyanobacterial symbioses are no longer regarded as mere oddities but as important components of the biosphere, occurring both in terrestrial and aquatic habitats worldwide. It is becoming apparent that they can enter into symbiosis with a wider variety of organisms than hitherto known, and there are many more still to be discovered, particularly in marine environments. The chapters cover cyanobacterial symbioses with plants (algae, bryophytes, Azolla, cycads, Gunnera), cyanobacterial symbioses in marine environments, lichens, Nostoc-Geosiphon (a fungus closely related to arbuscular mycorrhiza fungi) symbiosis, and artificial associations of cyanobacteria with economically important plants. In addition, cyanobiont diversity, sensing-signalling, and evolutionary aspects of the symbiosis are dealt with. Renowned experts actively involved in research on cyanobacterial symbioses deal with ecological, physiological, biochemical, molecular, and applied aspects of all known cyanobacterial symbioses. This volume on cyanobacteria in symbiosis complements the two earlier volumes on cyanobacteria published by Kluwer (Molecular Biology of Cyanobacteria, edited by D.A. Bryant and Ecology of Cyanobacteria, edited by B.A. Whitton and M. Potts). Together, the three volumes provide the most comprehensive treatment of cyanobacterial literature as a whole. The book will serve as a valuable reference work and text for teaching and research in the field of plant-microbe interactions and nitrogen fixation.
