Quantitative Methods In Landscape Ecology

Quantitative Methods In Landscape Ecology written by Monica G. Turner and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 1991 with Nature categories.

"Landscape ecology as a modern interdisciplinary science is making use increasingly of quantitative research techniques adopted from other fields. So far, no synthetic reference has been available to those wishing to acquaint themselves with new approaches to quantitative analysis of spatial heterogeneity at the landscape level. This book seeks to meet this need by providing a conceptual framework and illustrating potential applications for methods such as pattern analysis, spatial statistics, fractals modeling, broad-scale studies, and extrapolation across scales. Each technique is discussed in sufficient detail to be adaptable to a variety of research problems. Quantitative Methods in Landscape Ecology will be an important resource for researchers and students of landscape and ecosystem ecology in understanding and analyzing the dynamics of complex spatial systems."--

Lichen Physiology And Cell Biology

Lichen Physiology And Cell Biology written by D. H. Brown and has been published by Springer this book supported file pdf, txt, epub, kindle and other format this book has been release on 1985-12-31 with Nature categories.

It is currently impossible to grow lichens under controlled conditions in the laboratory in sufficient quantity for physiological experiments. Lichen growth is slow and conditions which might accelerate the process tend to favour either the algal or fungal partner, resulting in the breakdown of balance symbiosis. Lichen physiologists are therefore forced to use field-grown material with all the problems associated with the unknown influences of unpredictable and unreproducible climatic conditions. Study of major biochemical topics, such as the nature of the carbohydrate and nitrogenous compounds passing between the symbionts, is less influenced by climatic conditions than the intrinsic nature of the symbionts and many advances have been made in these areas. Recently, the challenge of using field-grown plant material, the physiological status of which is intimately linked to environmental conditions, has proved to be a stimulus rather than a hindrance to a number of research groups. The occurrence of lichens in extreme habitats has prompted a number of field and laboratory studies with material from such diverse localities as the cold deserts of Antarctica and the temperate rain forests of the New Zealand bush. A comparative approach, using contrasted species or habitats from a particular geographical region has yielded much information and an appreciation of the variety of physiological adaptations which may exist. The close linkage between morphology and physiology is now being directly demonstrated, as is the relevance of ultrastructural information.

Critical Loads

Critical Loads written by M. Hornung and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 1993 with Science categories.

The concept of critical loads is of great ecological, economic and political importance. Although a simple concept - the threshold at which a pollutant load causes harm to the environment - turning this basic idea into scientifically-acceptable criteria is an ambitious undertaking. Nevertheless, governments are pressing ahead with European legislation on air pollution based on acceptable critical loads. However, there has been little opportunity for the ecological community as a whole to participate in these vital discussions on European policy, or for those who have been involved to present the results of their deliberations to their scientific peers.
