Download or read book Insects and Diseases of Cottonwood written by and published by . This book was released on 1975 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects and disease organisms are a continuing threat to cottonwood (Populus deltoides Bartr.), especially during the tree's first 5 years. The danger is intensified in large plantings of a single species and age because rapid buildup of damaging agents can occur. This booklet, will help forest nurserymen and plantation managers identify and control pest problems. The major insects and diseases are illustrated; and information on their importance, signs of infestation, biology, and natural control is presented. Brief mention is made of other pests which may be of local or sporadic concern. A list of registered chemical controls is also provided. This list is subject to change as new materials are approved, and revisions will be made available at periodic intervals.

Download or read book From Kostenki to Clovis written by Olga Soffer and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 510 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the American Side I went to the USSR for the first time in 1982 to attend the 11th meeting of the International Union for Quaternary research (INQUA) held at the Moscow State University. At that time relations between our two countries were anything but congenial and many restrictions were placed on our viewing the archaeological and paleontological collections and labora tory facilities. This was not the ideal climate for the free exchange of ideas needed for meaningful research. However, it was obvious to us that the strained relations did not extend to scientific discussions between scholars. We left that meeting well aware that if the problems of prehistoric Old World-New World relationships were to be resolved, it would eventually require cooperative research efforts within the world community of archaeologists. At that time, the pre-Clovis problem in New World archaeology was foremost in the minds of many North American researchers: tool technology and assemblages were being studied as a possible means of establishing cultural relationships across the Bering Strait, Clovis sites and mammoth kills were being looked at with new ideas for interpretation, and New World researchers realized that to resolve these questions they had to become familiar with the archaeological record of northeast Asia. A chance meeting of the writer with Olga Soffer in 1983 led to serious discussions of the sites on the Russian or East European Plain.

Download or read book Native Speaker written by Chang-rae Lee and published by Penguin. This book was released on 1996-03-01 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: ONE OF THE ATLANTIC’S GREAT AMERICAN NOVELS OF THE PAST 100 YEARS The debut novel from critically acclaimed and New York Times–bestselling author of On Such a Full Sea and My Year Abroad. In Native Speaker, author Chang-rae Lee introduces readers to Henry Park. Park has spent his entire life trying to become a true American—a native speaker. But even as the essence of his adopted country continues to elude him, his Korean heritage seems to drift further and further away. Park's harsh Korean upbringing has taught him to hide his emotions, to remember everything he learns, and most of all to feel an overwhelming sense of alienation. In other words, it has shaped him as a natural spy. But the very attributes that help him to excel in his profession put a strain on his marriage to his American wife and stand in the way of his coming to terms with his young son's death. When he is assigned to spy on a rising Korean-American politician, his very identity is tested, and he must figure out who he is amid not only the conflicts within himself but also within the ethnic and political tensions of the New York City streets. Native Speaker is a story of cultural alienation. It is about fathers and sons, about the desire to connect with the world rather than stand apart from it, about loyalty and betrayal, about the alien in all of us and who we finally are.

Download or read book Wildland Fire in Ecosystems written by U. S. Department Of Agriculture and published by CreateSpace. This book was released on 2012-10 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This state-of-knowledge review about the effects of fire on flora and fuels can assist land managers in planning for ecosystem management and fire management, and in their efforts to inform others about the ecological role of fire. Chapter 1 presents an overview and a classification of fire regimes that is used throughout the report. Chapter 2 summarizes knowledge of fire effects on individual plants, including susceptibility to mortality of aerial crowns, stems, and roots; vegetative regeneration; seedling establishment from on-site and off-site seed sources; seasonal influences such as carbohydrates and phenological stage; and factors affecting burn severity. Five chapters describe fire regime characteristics such as fire severity, fire frequency, and fire intensity, and postfire plant community responses for ecosystems throughout the United States and Canada. Typical fuel compositions, fuel loadings, and fire behavior are described for many vegetation types. Vegetation types including Forest-Range Environmental Study (FRES), Kuchler, and Society of American Foresters (SAF) types are classified as belonging to understory, mixed, or stand replacement fire severity regime types. The severity and frequency of fire are described for the pre-Euro-American settlement period and contrasted with current fire regimes. Historic fire frequencies ranged from a fire every 1 to 3 years in some grassland and pine types to a fire every 500 to 1,000 years in some coastal forest and northern hardwood types. In many vegetation types characterized by understory fire regimes, a considerable shift in fire frequency and fire severity occurred during the past century. Successional patterns and vegetation dynamics following disturbance by fire, and in some cases related grazing and silvicultural treatments, are described for major vegetation types. Management considerations are discussed, especially for the application of prescribed fire. A chapter on global climate change describes the complexity of a changing climate and possible influences on vegetation, fuels, and fire. The uncertainty of global climate change and its interactions with vegetation means expectations for fire management are general and tentative. Nonetheless, manipulation of wildlands and disturbance regimes may be necessary to ensure continual presence of some species. The last chapter takes a broader, more fundamental view of the ecological principles and shifting fire regimes described in the other chapters. The influences of fire regimes on biodiversity and fuel accumulation are discussed. Strategies and approaches for managing fire in an ecosystem context and sources of technical knowledge that can assist in the process are described. Research needs are broadly summarized.
