Condizione: Fine. x, 488, text figs. . HB. Fine. Authoritative collection of papers on the world's leading wetlands - a must for all those who study these vital but rapidly shrinking natural areas.During the past century approximately fifty percent of the world's wetlands have been destroyed, largely due to human activities. Increased human population has lead to shrinkage of wetland areas, and data show that as they shrink, their important functions decline. Reduced wetland area causes more flooding in Spring, less available water during drought, greater risk of water pollution, and less food production and reduced carbon storage. Much of the remaining pristine wetland systems are found in the world's largest wetlands, and yet these areas have received surprisingly little scientific research or attention. This volume presents the views of leading experts on each of the world's largest wetland systems. Here, this international team of authors share their understanding of the ecological dynamics of large wetlands and their significance, and emphasise their need of conservation. [9780521834049]. …

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book has two principal objectives. The first is to provide an overview of existing knowledge about competition. The second is to organize this knowledge in such a way that new research paths are suggested. Such a treatment of competition is badly needed. Although there is a voluminous literature on the topic there is no recent synthesis to which experienced researchers or new students may turn. This is my attempt to provide such an overview. I have tried not only to summarize what is known, but also to stress the unknowns in the hope that some new and innovative research will result. A book such as this faces two challenges at the outset: the sheer volume of the literature, and the presence of established research traditions which determine how that literature is to be interpreted and understood. The literature on competition is as vast and diverse as beetles in the biosphere. How better to begin, then, than with the preface from Crowson's (1981) volume on the Coleoptera He observed: To deal with so vast a group as the Coleoptera . . . is doubtless an over ambitious aim for any single author; it is inevitable that my attempt to do so will not satisfy specialists in their own particular fields.…

Buch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Competition is one of the most important factors controlling the distribution and abundance of living creatures. Sperm cells racing up reproductive tracts, beetle larvae battling inside single seeds, birds defending territories, and trees interfering with the light available to neighbours, are all engaged in competition for limited resources. Along with predation and mutualism, competition is one of the three major biological forces that assemble living communities. Recent experimental work, much of it only from the last few decades, has enhanced human knowledge of the prevalence of competition in nature. There are acacia trees that use ants to damage vines, beetles that compete in arenas for access to dung balls, tadpoles that apparently poison their neighbours, birds that smash the eggs of potential competitors, and plants that associate with fungi in order to increase access to soil resources. While intended as an up-to-date reference work on the state of this branch of ecology, the many non-technical examples will make interesting reading for those with a general interest in nature. Greatly expanded from the first prize-winning edition, there are entirely new chapters, including one on resources and another on competition gradients in nature. The author freely ranges across all major taxonomic groups in search of evidence. The question of whether competition occurs is no longer useful, the author maintains; rather the challenge is to determine when and where each kind of competition is important in natural systems. For this reason, variants of competition such as intensity, asymmetry and hierarchies are singled out for particular attention. The book concludes with the difficulties of finding general principles in complex ecological communities, and illustrates the limitations on knowledge that arise out of the biased conduct of scientists themselves. Competition can be found elsewhere in living systems other than ecological communities, at sub-microscopic scales in the interactions of enzymes and neural pathways, and over large geographic areas in the spread of human populations and contrasting ideas about the world. Human societies are therefore also examined for evidence of the kinds of competition found among other living organisms. Using an array of historical examples, including Biblical conflicts, the use of noblemen's sons in the Crusades, the Viking raids in Europe, strategic bombing campaigns in the Second World War, and ethnic battles of the Balkans, the book illustrates how most of the aspects of competition illustrated with plants and animals can be extended to the interactions of human beings and their societies.…
