Available in PDF, EPUB and Kindle. Book excerpt: These investigations identify and clarify some basic assumptions and methodological principles involved in ecological explanations of plant associations. How are plants geographically distributed into characteristic groups? What are the basic conditions that organize groups of interspecific plant populations that are characteristic of particular kinds of habitats? Answers to these questions concerning the geographical distribution of plants in late 19th century European plant geography and early 20th century American plant ecology can be distinguished according to differing logical assumptions concerning the habitats of plant associations. Through an analysis of several significant case studies in the early history of plant ecology, Konopka distinguishes a logic of habitats that conceives of plant associations in an analogy to individual organisms with a logic that conceives of plant associations in a reciprocal relation to habitat physiography. He argues that a phenomenological conception of the logical attributes of habitats can philosophically complement the physiographic tradition in early plant ecology and provide an attractive alternative to standard reductionism and holism debates that persist today. This wide ranging and original analysis will be valuable for readers interested in the history and philosophy of ecology.

Download or read book Long Term Ecological Research written by Felix Müller and published by Springer Science & Business Media. This book was released on 2010-06-21 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecosystems change on a multitude of spatial and temporal scales. While analyses of ecosystem dynamics in short timespans have received much attention, the impacts of changes in the long term have, to a great extent, been neglected, provoking a lack of information and methodological know-how in this area. This book fills this gap by focusing on studies dealing with the investigation of complex, long-term ecological processes with regard to global change, the development of early warning systems, and the acquisition of a scientific basis for strategic conservation management and the sustainable use of ecosystems. Within this book, theoretical ecological questions of long-term processes, as well as an international dimension of long-term monitoring, observations and research are brought together. The outcome is an overview on different aspects of long-term ecological research. Aquatic, as well as terrestrial ecosystems are represented.

This book was released on 2013-03-13 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is ecology at a crossroad? After three decades of rapid, though somewhat anarchic development, many ecologists now are beginning to ask this question. They have the feeling of no longer belonging to a unified and mature scientific discipline. Many of them claim to be mere empiricists, whereas others are proud to be considered theoreticians. Each side has its own journals and holds its own specialists' meetings, tending to disregard the achievements of the other. The communication gap between the two schools is quickly widening, to the detriment of both. To make things worse, the word "ecology" now has a different meaning for the professional biologists and the general public. Ecology is still considered as a creditable (though rather "soft") scientific discipline by the former, whereas it is perceived as a new, non-conformist political philosophy by the latter. Empirical ecologists are fundamentally naturalists who enjoy the immense complexity of the natural world and devote their lifetimes to the description of the many adaptive characteristics--morpholog ical, biological, or behavioral--of the hundreds of thousands of species sharing the earth with us. They generally are ignorant of, if not allergic to, the use of any mathematical representation of living phenomena. They' feel that ecological theory is rapidly becoming a mathematical game that has lost any contact with the "realities of life.

Download or read book Standard Soil Methods for Long Term Ecological Research written by G. Philip Robertson and published by Oxford University Press. This book was released on 1999-10-28 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Standardized methods and measurements are crucial for ecological research, particularly in long-term ecological studies where the projects are by nature collaborative and where it can be difficult to distinguish signs of environmental change from the effects of differing methodologies. This second volume in the Long-Term Ecological Research (LTER) Network Series addresses these issues directly by providing a comprehensive standardized set of protocols for measuring soil properties. The goal of the volume is to facilitate cross-site synthesis and evaluation of ecosystem processes. Chapters cover methods for studying physical and chemical properties of soils, soil biological properties, and soil organisms, and they include work from many leaders in the field. The book is the first broadly based compendium of standardized soil measurement methods and will be an invaluable resource for ecologists, agronomists, and soil scientists.

Download or read book Human and Ecological Risk Assessment written by Dennis J. Paustenbach and published by John Wiley & Sons. This book was released on 2024-04-15 with total page 1319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understand the fundamentals of human risk assessment with this introduction and reference Human risk assessments are a precondition for virtually all industrial action or environmental regulation, all the more essential in a world where chemical and environmental hazards are becoming more abundant. These documents catalog potential environmental, toxicological, ecological, or other harms resulting from a particular hazard, from chemical spills to construction projects to dangerous workplaces. They turn on a number of variables, of which the most significant is the degree of human exposure to the hazardous agent or process. Human and Ecological Risk Assessment combines the virtues of a textbook and reference work to introduce and analyze these vital documents. Beginning with the foundational theory of human health risk assessment, it then supplies case studies and detailed analysis illustrating the practice of producing risk assessment documents. Fully updated and authored by leading authorities in the field, the result is an indispensable work. Readers of the second edition of Human and Ecological Risk Assessment will also find: Over 40 entirely new case studies reflecting the latest in risk assessment practice Detailed discussion of hazards including air emissions, contaminated food and soil, hazardous waste sites, and many more Case studies from multiple countries to reflect diverse international standards Human and Ecological Risk Assessment is ideal for professionals and advanced graduate students in toxicology, industrial hygiene, occupational medicine, environmental science, and all related subjects.
