Download or read book Pollination Biology written by Dharam P. Abrol and published by Springer Science & Business Media. This book was released on 2011-10-05 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Download or read book Status of Pollinators in North America written by National Research Council and published by National Academies Press. This book was released on 2007-05-13 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the female parts of flowers for plant reproduction-are an essential part of natural and agricultural ecosystems throughout North America. For example, most fruit, vegetable, and seed crops and some crops that provide fiber, drugs, and fuel depend on animals for pollination. This report provides evidence for the decline of some pollinator species in North America, including America's most important managed pollinator, the honey bee, as well as some butterflies, bats, and hummingbirds. For most managed and wild pollinator species, however, population trends have not been assessed because populations have not been monitored over time. In addition, for wild species with demonstrated declines, it is often difficult to determine the causes or consequences of their decline. This report outlines priorities for research and monitoring that are needed to improve information on the status of pollinators and establishes a framework for conservation and restoration of pollinator species and communities.

Download or read book The Sibley Guide to Trees written by David Allen Sibley and published by Knopf. This book was released on 2009-09-15 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The definitive field guide to the trees of North America, featuring maps, detailed illustrations, and information on more than 600 species of trees, from the preeminent, bestselling author and illustrator “A beautiful, masterful, and much-needed work that will henceforth be our guide to the North American trees.”—Edward O. Wilson The Sibley Guide to Trees is an astonishingly elegant guide to a complex subject. It condenses a huge amount of information about tree identification—more than has ever been collected in a single book—into a logical, accessible, easy-to-use format. With more than 4,100 meticulous, exquisitely detailed paintings, the Guide highlights the often subtle similarities and distinctions between more than 600 tree species—native trees as well as many introduced species. More than 500 maps show the complete range, both natural and cultivated, for nearly all species. No other guide has ever made field identification so clear. Highlighted features include: • leaves (including multiple leaf shapes and fall leaf color) • bark • needles • cones • flowers • fruit • twigs • silhouettes Trees are arranged taxonomically, with all related species grouped together. By focusing on the fundamental characteristics of, for example, oaks or chestnuts or hickories, the Guide helps the user recognize these basic species groups the same way birders recognize thrushes, warblers, or sparrows. In addition, there are essays on taxonomy, on the cultivation of trees, and on conservation issues, reflecting Sibley’s deep concern with habitat preservation and environmental health. An important contribution to our understanding of the natural world, The Sibley Guide to Trees is a necessity for every tree lover, traveler, and naturalist.
Download or read book Changes in the Land written by William Cronon and published by Hill and Wang. This book was released on 2011-04-01 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book that launched environmental history, William Cronon's Changes in the Land, now revised and updated. Winner of the Francis Parkman Prize In this landmark work of environmental history, William Cronon offers an original and profound explanation of the effects European colonists' sense of property and their pursuit of capitalism had upon the ecosystems of New England. Reissued here with an updated afterword by the author and a new preface by the distinguished colonialist John Demos, Changes in the Land, provides a brilliant inter-disciplinary interpretation of how land and people influence one another. With its chilling closing line, "The people of plenty were a people of waste," Cronon's enduring and thought-provoking book is ethno-ecological history at its best.

Available in PDF, EPUB and Kindle. Book excerpt: A page-turning novel that is also an exploration of the great philosophical concepts of Western thought, Jostein Gaarder's Sophie's World has fired the imagination of readers all over the world, with more than twenty million copies in print. One day fourteen-year-old Sophie Amundsen comes home from school to find in her mailbox two notes, with one question on each: "Who are you?" and "Where does the world come from?" From that irresistible beginning, Sophie becomes obsessed with questions that take her far beyond what she knows of her Norwegian village. Through those letters, she enrolls in a kind of correspondence course, covering Socrates to Sartre, with a mysterious philosopher, while receiving letters addressed to another girl. Who is Hilde? And why does her mail keep turning up? To unravel this riddle, Sophie must use the philosophy she is learning—but the truth turns out to be far more complicated than she could have imagined.

Download or read book Historical Dictionary of Mesoamerica written by Walter Robert Thurmond Witschey and published by Scarecrow Press. This book was released on 2012 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mesoamerica is one of six major areas of the world where humans independently changed their culture from a nomadic hunter-gatherer lifestyle into settled communities, cities, and civilization. In addition to China (twice), the Indus Valley, the Fertile Crescent of southwest Asia, Egypt, and Peru, Mesoamerica was home to exciting and irreversible changes in human culture called the "Neolithic Revolution." The changes included domestication of plants and animals, leading to agriculture, husbandry, and eventually sedentary village life. These developments set the stage for the growth of cities, social stratification, craft specialization, warfare, writing, mathematics, and astronomy, or what we call the rise of civilization. These changes forever transformed humankind. The Historical Dictionary of Mesoamerica covers the history of Mesoamerica through a chronology, an introductory essay, an extensive bibliography, and over 900 cross-referenced dictionary entries covering the major peoples, places, ideas, and events related to Mesoamerica. This book is an excellent access point for students, researchers, and anyone wanting to know more about Mesoamerica.
Download or read book A Sanctuary in the Hora of Illyrian Apollonia written by Jack L. Davis and published by Lockwood Press. This book was released on 2022-06-01 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the years 2004-2006, a joint team from the International Centre for Albanian Archaeology in Tirana, Albania, the Institute of Archaeology in Tirana, and the University of Cincinnati conducted excavations in the plain west of the walls of the ancient Greek colony of Apollonia, a short distance to the southwest of the modern village of Pojan. The site lies almost entirely within a complex of farm buildings known locally as Bonjaket. This volume represents the full publication of the results of three campaigns of excavation at the site. The new excavations discovered and documented a previously unknown monumental temple and have made it possible to describe for the first time the material remains of Greek rituals as practiced at the time of, or not long after, the foundation of Apollonia.

Download or read book The Chrysokamino Metallurgy Workshop and Its Territory written by Philip P. Betancourt and published by ASCSA. This book was released on 2006 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: This detailed report describes archaeological fieldwork conducted between 1995 and 1997 in rural northeast Crete. Excavations were made in two locations: a metallurgy workshop (abandoned in EM III) and a nearby rural habitation site, perhaps a farmhouse (used until LM III). An intensive survey of the vicinity revealed other activities in the area from the Early Neolithic onwards, and placed the sites in a micro-regional context. A publication of the Minoan farmhouse will appear subsequently, but this volume stands on its own as both an overview of the project and as a detailed study of the copper smelting workshop.
Download or read book Bark and Wood Boring Insects in Living Trees in Europe a Synthesis written by François Lieutier and published by Springer Science & Business Media. This book was released on 2007-08-24 with total page 569 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the first time, a synthesis on the research work done in Europe on all Bark And Wood Boring Insects In Living Trees (BAWBILT) is presented. As final product of a four-year research project gathering together 100 scientists from 24 countries, the book is the fruit of a real collective synthesis in which all European specialists have participated. It reviews and comments on all the European literature, while considering the biological (trees, insects, associated organisms, and their relationships) and forest management aspects. However, although focused on the European forest, it also compares the available information and interpretations to those concerning similar species in other continents. It ends with propositions of research priorities for Europe. The book is directed to all scientists and students concerned with forest entomology and ecology, as well as to forest managers and all scientific public interested in forest biology.
