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 Allelopathy written by Manuel J. Reigosa and published by Springer Science & Business Media. This book was released on 2006-02-28 with total page 635 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are many good books in the market dealing with the subject of allelopathy. When we designed the outline of this new book, we thought that it should include as many different points of view as possible, although in an integrated general scheme. Allelopathy can be viewed from different of perspectives, ranging from the molecular to the ecosystem level, and including molecular biology, plant biochemistry, plant physiology, plant ecophysiology and ecology, with information coming also from the organic chemistry, soil sciences, microbiology and many other scientific disciplines. This book was designed to include a complete perspective of allelopathic process. The book is divided into seven major sections. The first chapter explores the international development of allelopathy as a science and next section deals with methodological aspects and it explores potential limitations of actual research. Third section is devoted to physiological aspects of allelopathy. Different specialists wrote about photosynthesis, cell cycle, detoxification processes, abiotic and biotic stress, plant secondary metabolites and respiration related to allelopathy. Chapters 13 through 16 are collectively devoted to various aspects of plant ecophysiology on a variety of levels: microorganisms, soil system and weed germination. Fundamental ecology approaches using both experimental observations and theoretical analysis of allelopathy are described in chapters 16 and 17. Those chapters deal with the possible evolutionary forces that have shaped particular strategies. In the section named “allelopathy in different environments”, authors primarily center on marine, aquatic, forest and agro ecosystems. Last section includes chapters addressing application of the knowledge of allelopathy.

Download or read book Historical Dictionary of the Republic of Cameroon written by Mark Dike DeLancey and published by Scarecrow Press. This book was released on 2010-05-03 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cameroon is a country endowed with a variety of climates and agricultural environments, numerous minerals, substantial forests, and a dynamic population. It is a country that should be a leader of Africa. Instead, we find a country almost paralyzed by corruption and poor management, a country with a low life expectancy and serious health problems, and a country from which the most talented and highly educated members of the population are emigrating in large numbers. Although Cameroon has made economic progress since independence, it has not been able to change the dependent nature of its economy. The economic situation combined with the dismal record of its political history, indicate that prospects for political stability, justice, and prosperity are dimmer than they have been for most of the country's independent existence. The fourth edition of the Historical Dictionary of the Republic of Cameroon has been updated to reflect advances in the study of Cameroon's history as well as to provide coverage of the years since the last edition. It relates the turbulent history of Cameroon through a chronology, an introductory essay, a bibliography, and over 600 cross-referenced dictionary entries on significant persons, events, places, organizations, and other aspects of Cameroon history from the earliest times to the present.
Download or read book Assessing Site Significance written by Donald L. Hardesty and published by Rowman Altamira. This book was released on 2009-03-16 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: Assessing Site Significance is an invaluable resource for archaeologists and others who need guidance in determining whether sites are eligible for listing in the National Register of Historic Places (NRHP). Because the register's eligibility criteria were largely developed for standing sites, it is difficult to know in any particular case whether a site known primarily through archaeological work has sufficient 'historical significance' to be listed. Hardesty and Little address these challenges, describing how to file for NRHP eligibility and how to determine the historical significance of archaeological properties. This second edition brings everything up to date, and includes new material on 17th- and 18th-century sites, traditional cultural properties, shipwrecks, Japanese internment camps, and military properties.
