Book excerpt: Since the 1970s and particularly the works of Tüxen (1978) and Géhu & Rivas-Martínez (1981), dynamico-catenal phytosociology has facilitated the integration of vegetation dynamics by more precisely describing the trajectories of vegetation series. A national habitat mapping program (CarHAB), launched by France’s Ministry of Ecology, aims to map the vegetation and vegetation series of metropolitan France at a scale of 1: 25,000 by 2025. In this context, Corsica has been selected as a pilot region, due to its unique characteristics regarding Mediterranean and alticole vegetation. This book describes in detail the vegetation series and geoseries (ecology, structure, dynamic trajectories, effects of anthropogenic factors on vegetation dynamics, catenal positioning in the landscape) of two Corsican sectors: Cap Corse and Biguglia pond. These two study sites were selected using two methods: • For Cap Corse, the typology and mapping are based on an inductive approach, which seeks to understand the dynamics of vegetation by drawing on the mature, substitutional, pioneering and anthropogenic associations likely to exist within a tessellar envelope. These various dynamic stages characterize “the vegetation series” (sigmetum or synassociation), the fundamental unit of symphytosociology (Géhu 2006; Biondi 2011). The aim of symphytosociology is, therefore, to define the vegetation series; in other words, it seeks to identify the repetitive combinations of syntaxa under homogeneous ecological conditions. • For Biguglia pond, the typology and mapping are based on a deductive approach, which combines (under SIG) the ecological descriptor maps with the vegetation mapping, in order to reveal the tesselas and the natural potential vegetation that underlies them. Thanks to the improvement of GIS techniques, this approach has been frequently used to characterize plant landscapes from vegetation to vegetation geoseries since the 2000s, with applications to the conservation management of natural and semi-natural environments.
Download or read book Tree Rings and Climate written by H Fritts and published by Elsevier. This book was released on 2012-12-02 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree Rings and Climate deals with the principles of dendrochronology, with emphasis on tree-ring studies involving climate-related problems. This book looks at the spatial and temporal variations in tree-ring growth and how they can be used to reconstruct past climate. Factors and conditions that appear most relevant to tree-ring research are highlighted. Comprised of nine chapters, this book opens with an overview of the basic biological facts and principles of tree growth, as well as the most important terms, principles, and concepts of dendrochronology. The discussion then shifts to the basic biology governing the response of ring width to variation in climate; systematic variations in the width and cell structure of annual tree rings; and the significance of tree growth and structure to dendroclimatology. The movement of materials and internal water relations of trees are also considered, along with photosynthesis, respiration, and the climatic and environmental system. Models of the growth-climate relationships as well as the basic statistics and methods of analysis of these relationships are described. The final chapter includes a general discussion of dendroclimatographic data and presents examples of statistical models that are useful for reconstructing spatial variations in climate. This monograph will be of interest to climatologists, college students, and practitioners in fields such as botany, archaeology, hydrology, oceanography, biology, physiology, forestry, and geophysics.

Download or read book Woodland Conservation and Management written by George Peterken and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Professor John Harper, in his recent Population Biology of Plants (1977), made a comment and asked a question which effectively states the theme of this book. Noting that 'one of the consequences of the development of the theory of vegetational climax has been to guide the observer's mind forwards', i. e. that 'vegetation is interpreted as a stage on the way to something' , he commented that 'it might be more healthy and scientifically more sound to look more often backwards and search for the explanation of the present in the past, to explain systems in relation to their history rather than their goal'. He went on to contrast the 'disaster theory' of plant succession, which holds that communities are a response to the effects of past disasters, with the 'climax theory', that they are stages in the approach to a climax state, and then asked 'do we account most completely for the characteristics of a population by a knowledge of its history or of its destiny?' Had this question been put to R. S. Adamson, E. J. Salisbury, A. G. Tansley or A. S. Watt, who are amongst the giants of the first forty years of woodland ecology in Britain, their answer would surely have been that understanding lies in a knowledge of destiny. Whilst not unaware of the historical facts of British woodlands, they were preoccupied with ideas of natural succession and climax, and tended to interpret their observations in these terms.

Download or read book Mammals of the Holy Land written by Mazin B. Qumsiyeh and published by Texas Tech University Press. This book was released on 1996 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 110 species of mammals roamed the forests, mountains, and deserts of this ancient "Land of Canaan"--Jordan, Israel, Syria, Lebanon, Palestine. Their impact on humans can be seen in cave drawings made by the Neanderthal inhabitants of northern Palestine some 200,000 years ago and gleaned from the writings of all Near Eastern civilizations. In recent centuries, encroachment by an increasing human population has resulted in the extinction of several species--aurochs (wild ox), red deer, onagers, Syrian wild asses roebucks (roe deer), fallow deer, Syrian brown bears, and cheetahs. Currently at risk are such large mammals as the leopard, wolf, wild cat, caracal, ibex, and dessert gazelles as well as may small mammals especially small carnivores, insectivores, and bats. Mammals of the Holy Land, summarizes the information that is known about the mammals that inhabit this historic land. with keys to identification, a glossary of terms, a basic introduction to the study of mammals, and a discussion of the impact these mammals have had on humans, a well as taxonomic and natural history information for each species, this book will be useful to both the professional and non-professional.

Download or read book Dendroecology written by Mariano M. Amoroso and published by Springer. This book was released on 2017-12-12 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dendroecologists apply the principles and methods of tree-ring science to address ecological questions and resolve problems related to global environmental change. In this fast-growing field, tree rings are used to investigate forest development and succession, disturbance regimes, ecotone and treeline dynamics and forest decline. This book of global scope highlights state-of-the-science dendroecological contributions to paradigm-shifts in our understanding of ecophysiology, stand dynamics, disturbance interactions, forest decline and ecosystem resilience to global environmental change and is fundamental to better managing our forested ecosystems for the full range of ecosystem goods and services that they provide.
Download or read book Methods of Dendrochronology written by E.R. Cook and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a review and description of the state-of-the-art methods of tree-ring analy~is with specific emphasis on applications in the environmental sciences. Traditionally, methods of tree-ring analysis, or more properly in this case methods 0/ dendrochronology, were developed and used for dating archaeological and historical structures and for reconstructing past climates. The classic book Tree Rings and Climate, by H.C. Fritts, published in 1976, provided a superb introduction to the science and an in-depth description of techniques useful for extracting climatic information from tree rings. This book, which was published by Academic Press, is sadly out of print and, even though only 12 years old, lim ited in its methods and applications. This is owing to the extremely rapid development of the science since the 1970s. Only recently have tree rings as environmental sensors been fully recog nized as a valuable tool in detecting environmental change. For example, tree ring measurements have been critically important in studies of forest decline in Europe and North America. There are also attempts to use tree-ring analysis for ecological prognosis to solve large-scale regional problems including the sustain ability of water supplies, prediction of agricultural crops, and adoption of silvi cultural measures in response to ecological changes. More speculatively, dendro chronological methods are also used for dating and evaluating some astrophysical phenomena and for indicating possible increase in the biospheric carrying capac ity due to increased atmospheric carbon dioxide.

Download or read book Stable Isotopes in Ecology and Environmental Science written by Robert Michener and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights new and emerging uses of stable isotope analysis in a variety of ecological disciplines. While the use of natural abundance isotopes in ecological research is now relatively standard, new techniques and ways of interpreting patterns are developing rapidly. The second edition of this book provides a thorough, up-to-date examination of these methods of research. As part of the Ecological Methods and Concepts series which provides the latest information on experimental techniques in ecology, this book looks at a wide range of techniques that use natural abundance isotopes to: follow whole ecosystem element cycling understand processes of soil organic matter formation follow the movement of water in whole watersheds understand the effects of pollution in both terrestrial and aquatic environments study extreme systems such as hydrothermal vents follow migrating organisms In each case, the book explains the background to the methodology, looks at the underlying principles and assumptions, and outlines the potential limitations and pitfalls. Stable Isotopes in Ecology and Environmental Science is an ideal resource for both ecologists who are new to isotopic analysis, and more experienced isotope ecologists interested in innovative techniques and pioneering new uses.
Download or read book Grazing and Conservation Management written by Michiel F. WallisDe Vries and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grazing animals enjoy an ambiguous reputation in the field of nature conservation. Livestock are often treated as a scourge, yet native large herbivores form the prime attraction of many a reserve. This book gives the first comprehensive overview of the use of grazing as a tool in conservation management. Considering in turn the ecological and historical background, the impact of grazing on community structure, management applications and future prospects, this book examines issues such as the role of herbivores as keystone species, the assessment of habitat quality and the function of scientific models in advancing grazing management. Large herbivores are shown to be potentially powerful allies in the management of nature reserves, particularly in the maintenance, enhancement or restoration of biodiversity. Grazing and Conservation Management will appeal to conservation biologists and rangeland managers, providing them with a clearer understanding of grazing and conservation management.

As forests are the main carbon sink on land, the results are of great importance for all global change studies.
Download or read book The Impacts of Climate Variability on Forests written by Martin Beniston and published by Springer. This book was released on 2006-04-10 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of scientific papers which were presented at an international workshop on the impacts of climatic variability held in Wengen, Switzerland, September 1997. For the first time, an assessment is made of the interactions between physical and biological elements of the Earth System on the basis of shifts in extreme climatic conditions, rather than simply changes in mean atmospheric conditions which research has tended to focus on until recently. Natural ecosystems and forests are typical examples of systems which, while constrained within certain ranges of mean climate, can undergo rapid and often irreversible damage in the face of short-lived but intense extreme events.
