Download or read book The Pollination Biology of North American Orchids Volume 1 written by Charles L. Argue and published by Springer Science & Business Media. This book was released on 2011-09-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have revealed remarkable complexity and diversity in orchid-pollinator relationships. These studies comprise a vast literature currently scattered in numerous, often obscure, journals and books. The Pollination Biology of North American Orchids brings together, for the first time, a comprehensive treatment of this information for all native and introduced North American orchids found north of Mexico and Florida. It provides detailed information on genetic compatibility, breeding systems, pollinators, pollination mechanisms, fruiting success, and limiting factors for each species. Distribution, habitat, and floral morphology are also summarized. In addition, detailed line drawings emphasize orchid reproductive organs and their adaptation to known pollinators. This, the first of two volumes, furnishes a brief introduction to the general morphology of the orchid flower and the terminology used to describe orchid breeding systems and reproductive strategies. It treats the lady’s-slippers of genus Cypripedium, subfamily Cypripedioideae, and nine genera of the subfamily Orchidoideae, including the diverse rein orchids of genus Platanthera. The Pollination Biology of North American Orchids will be of interest to both regional and international audiences including: Researchers and students in this field of study who are currently required to search through the scattered literature to obtain the information gathered here. Researchers and students in related fields with an interest in the co-evolution of plants and insects. Conservation specialists who need to understand both the details of orchid reproduction and the identity of primary pollinators in order to properly manage the land for both. Orchid breeders who require accurate and current information on orchid breeding systems. General readers with an interest in orchid biology. Charles Argue, Ph.D., is a plant biologist at the University of Minnesota specializing in the study of pollen grains. His articles have appeared in numerous journals including the American Journal of Botany, International Journal of Plant Sciences (formerly Botanical Gazette), Botany (formerly Canadian Journal of Botany), Grana, Pollen et Spores, North American Native Orchid Journal, The Native Orchid Conference Journal, Fremontia, and as chapters in a number of books.

Download or read book Atlas of Crustacean Larvae written by Joel W. Martin and published by JHU Press. This book was released on 2014-07 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: An illustrated guide to the sweeping diversity of crustacean larval forms. Winner of the CHOICE Outstanding Academic Title of the Choice ACRL Crustaceans—familiar to the average person as shrimp, lobsters, crabs, krill, barnacles, and their many relatives—are easily one of the most important and diverse groups of marine life. Poorly understood, they are among the most numerous invertebrates on earth. Most crustaceans start life as eggs and move through a variety of morphological phases prior to maturity. In Atlas of Crustacean Larvae, more than 45 of the world's leading crustacean researchers explain and illustrate the beauty and complexity of the many larval life stages. Revealing shapes that are reminiscent of aliens from other worlds—often with bizarre modifications for a planktonic life or for parasitization, including (in some cases) bulging eyes, enormous spines, and aids for flotation and swimming—the abundant illustrations and photographs show the detail of each morphological stage and allow for quick comparisons. The diversity is immediately apparent in the illustrations: spikes that deter predators occur on some larvae, while others bear unique specializations not seen elsewhere, and still others appear as miniature versions of the adults. Small differences in anatomy are shown to be suited to the behaviors and survival mechanisms of each species. Destined to become a key reference for specialists and students and a treasured book for anyone who wishes to understand "the invertebrate backbone of marine ecosystems," Atlas of Crustacean Larvae belongs on the shelf of every serious marine biologist.

Download or read book Glaciers of the Karakoram Himalaya written by Kenneth Hewitt and published by Springer Science & Business Media. This book was released on 2013-09-12 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Karakoram contains the greatest concentration of glaciers and most of the largest ice masses outside high latitudes. They comprise major stores and sources of fresh water in an otherwise extreme, continental, dry region. As many as 200 million people living downstream, in the valleys of the Indus and Yarkand Rivers, depend on melt waters from snow and ice. They are at risk from climate-change impacts on glaciers and water supply, and from hazards such as glacial lake outburst floods. Useful research initiatives go back to the nineteenth century, but coverage has generally been limited geographically and has not been continuous over time. It is almost 80 years since a monograph was devoted to the Karakoram glaciers. The book presents a comprehensive overview, including statistics for the ice cover, glacier mass balance and dynamics, glacierized landscapes, rock glaciers, water resources and environmental hazards. Published glaciological and related research is surveyed along with expedition reports and archival materials in several languages. The expanding potential of satellite coverage is exploited, but conditions and processes reported from field investigations are the main focus. Previously unpublished observations by the author are presented, based on some 45 years of work in the region. Broad understanding of the glacial environment is used to address emerging concerns about the High Asian cryosphere and the fate of its glaciers. These are discussed in relation to the pressing issues of water supply, environmental risk and sustainability. Questions of what is not known help identify much needed monitoring and research. The book is of interest to researchers, professionals, and those studying glaciers, mountain environments, water resources and environmental hazards. The topics discussed should be of concern for anyone involved in regional development and global change in South and Inner Asia.

Available in PDF, EPUB and Kindle. Book excerpt: Optics and photonics technologies are ubiquitous: they are responsible for the displays on smart phones and computing devices, optical fiber that carries the information in the internet, advanced precision manufacturing, enhanced defense capabilities, and a plethora of medical diagnostics tools. The opportunities arising from optics and photonics offer the potential for even greater societal impact in the next few decades, including solar power generation and new efficient lighting that could transform the nation's energy landscape and new optical capabilities that will be essential to support the continued exponential growth of the Internet. As described in the National Research Council report Optics and Photonics: Essential Technologies for our Nation, it is critical for the United States to take advantage of these emerging optical technologies for creating new industries and generating job growth. The report assesses the current state of optical science and engineering in the United States and abroad-including market trends, workforce needs, and the impact of photonics on the national economy. It identifies the technological opportunities that have arisen from recent advances in, and applications of, optical science and engineering. The report also calls for improved management of U.S. public and private research and development resources, emphasizing the need for public policy that encourages adoption of a portfolio approach to investing in the wide and diverse opportunities now available within photonics. Optics and Photonics: Essential Technologies for our Nation is a useful overview not only for policymakers, such as decision-makers at relevant Federal agencies on the current state of optics and photonics research and applications but also for individuals seeking a broad understanding of the fields of optics and photonics in many arenas.

Download or read book Family group Names of Recent Fishes written by Richard Van Der Laan and published by . This book was released on 2014 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The family-group names of animals (superfamily, family, subfamily, supertribe, tribe and subtribe) are regulated by the International Code of Zoological Nomenclature. Family names are particularly important because they are among the most widely used of all technical animal names. Apart from using the correct family-group name according to the Code, it is also important to use one unique universal name (with a fixed spelling) to avoid confusion. We have compiled a list of familygroup names for Recent fishes, applied the rules of the Code and, if possible, tried to conserve the names in prevailing recent practice. We list all of the family-group names found to date for Recent fishes (N=2625), together with their author(s) and year of publication. This list can be used in assigning the correct family-group name to a genus or a group of genera. With this publication we contribute to the usage of correct, universal family-group names in the classification of, and for communication about, Recent fishes.
