This book was released on 2012-12-06 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: R. K. Peet Dep. of Botany, University of North Carolina, Chapel Hill, N. C. 27514, USA Robert Whittaker's contributions to ecology were many and remarkably varied. His publication record will long stand as a monument to his greatness, and whatever we do to honor him will likely be rather small in comparison. Less well known were his personal interactions and the impact they had on the development of ecology as well as individual scientists. Over the years he touched many of us and we felt not just a professional but also a deep personal loss in his passing. After his death I was contacted by numerous colleagues who wondered what they might do to honor him. Whittaker had long served on the editorial board of Vegetatio, which prompted Eddy van der Maarel to suggest that a series of papers in the journal might be a fitting memorial, and so this project was conceived. Whittaker was a master of synthesis and during his career he published numerous review papers which showed clearly how his work related to and built on that of others. For this reason it seemed inappropriate and redundant to solicit papers reviewing areas to which Whittaker made important contributions. Instead, I chose to solicit research papers illustrating current applications of approaches Whittaker developed and showing a few of the recent advances which have grown directly from his pioneering work.

Book Synopsis Ordination of Plant Communities by : R.H. Whittaker
Download or read book Ordination of Plant Communities written by R.H. Whittaker and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large part of ecological research depends on use of two ap proaches to synthesizing information about natural communities: classification of communities (or samples representing these) into groups, and ordination (or arrangement) of samples in relation to environmental variables. A book published in 1973, 'Ordination and Classification of Communities,' sought to provide, through contributions by an international panel of authors, a coherent treatise on these methods. The book appeared then as Volume 5 of the Handbook of Vegetation Science, for which R. TuxEN is general editor. The desire to make this work more widely available in a less expensive form is one of the reasons for this second edition separating the articles on ordinction and on classification into two volumes. The other reason is the rapid advancement of understanding in the area of indirect ordination-mathematical techniques that seek to use measurements of samples from natural communities to produce arrangements that reveal environmental relationships of these communities. Such is the rate of change in this area that the last chapter on ordination in the first edition is already, 4 or 5 years after it was written, out of date; and new techniques of indirect ordination that could only be mentioned as possibilities in the first edition are becoming prominent in the field. In preparing the second edition the chapter on evaluation of ordinations has been rewritten, a new chapter on recent developments in continuous multivariate techniques has been included, and references to recent work have been added to other chapters.

Download or read book Murray Springs written by C. Vance Haynes and published by University of Arizona Press. This book was released on 2022-04-05 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Murray Springs Site in the upper San Pedro River Valley of southeast Arizona is one of the most significant Clovis sites ever found. It contained a multiple bison kill, a mammoth kill, and possibly a horse kill in a deeply stratified sedimentary context. Scattered across the buried occupation surface with the bones of late Pleistocene animals were several thousand stone tools and waste flakes from their manufacture and repair. Because of the unique occurrence of an algal black mat that buried the Clovis-age surface immediately after abandonment, the distributional integrity of the artifacts and debitage clusters is exceptional for Paleoindian sites. Excavation of the Clovis hunters’ camp 50 to 150 meters south of the kills revealed artifactual evidence typical of hunting camp activity, including hide working and weapons repair. Impact flakes conjoining with Clovis points clearly tied the camp to the bison kill. The unique nature of the site and this comprehensive study of the excavated material constitute one of the most important contributions to our knowledge of Paleoindian hunters in the New World.

Book Synopsis Packrat Middens by : Julio L. Betancourt
Download or read book Packrat Middens written by Julio L. Betancourt and published by University of Arizona Press. This book was released on 2021-11-16 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past thirty years, late Quaternary environments in the arid interior of western North America have been revealed by a unique source of fossils: well-preserved fragments of plants and animals accumulated locally by packrats and quite often encased, amberlike, in large masses of crystallized urine. These packrat middens are ubiquitous in caves and rock crevices throughout the arid West, where they can lie preserved for tens of thousands of years. More than a thousand of these deposits have been dated and analyzed, and middens have supplanted pollen records as a touchstone for studying vegetation dynamics and climatic change in radiocarbon time (the last 40,000 years). Now, similar deposits made by other mammals like hyraxes are being reported from other parts of the world. This book brings together the findings and views of many of the researchers investigating fossil middens in the United States, Mexico, Africa, the Middle East, and Australia. The contributions serve to open a forum for methodological concerns, update the fossil record of various geographic regions, introduce new applications, and display the vast potential for fossil midden analysis in arid regions worldwide. The findings presented here will serve to foster regional research and to promote general studies devoted to global climate change. Included in the text are more than two hundred charts, photographs, and maps.
