  • Ecology studies interactions among organisms and between organisms and their environment in nature and is also concerned with the effects that organisms have on the inanimate environment. It is concerned with not only what kind of air a species must have but also what effect that species has on the air. This book is not an elementary ecology textbook. A textbook would be longer and more didactic.

  • The study of wetland plants has been of interest to botanists for many years, but the need to identify and understand these plants has expanded dramatically since the 1970s. At that time, ecologists began to make known the vital role that wetlands play in our landscapes. The image of wetlands has shifted from that of mosquito-ridden wastelands to natural areas of critical importance. Because the field of wetland ecology has expanded, so has the study of the plants that thrive there, and their role in ecosystem dynamics.

  • Drawing on the collective expertise of world authorities, Ecological Basis of Agroforestry employs extensive use of tables and figures to demonstrate how ecologically sustainable agroecosystems can meet the challenges of enhancing crop productivity, soil fertility, and environmental sustainability. Divided into four sections, this comprehensive volume begins with a study of tree-crop interaction in tropical and temperate climates.

  • The discipline of Landscape Ecology is rapidly emerging as a motive force, both in the domain of theoretical ecology, and in applied fields such as biodiversity conservation planning. Without it and its further development, the more reductionist elements of, and approaches to, ecology will continue to make the discipline decreasingly relevant to land management, which will be made totally on the basis of politics and socioeconomics.

  • Enzymes that function within plants, animals, and microorganisms are fundamental to life, and their contributions to metabolic pathways and processes have been studied extensively. For over 100 years there has been interest in what today is called ecological or environmental enzymology. This aspect of enzymology originates from the work of Woods, who, in 1899, wrote about the survival and function in soil of plant peroxidases following their release from decaying plant roots.

  • In response to a growing need to bridge aspects of geography and ecology, Troll (1950, 1968) coined the term “landscape ecology,” which was adopted as a new scientific discipline. According to Troll (1968), the landscape can be studied in terms of its morphology, classification, and changes in time (history), as well as the functional relationships between its components, which he called landscape ecology. Troll also considered that problems of landscape protection as well as management should be included in geographical analyses of landscapes.

  • Research in tropical forestry is confronted with the task of finding strategies to alleviate pressure on remaining forests, and techniques to enhance forest regeneration and restore abandoned lands, using productive alternatives that can be attractive to local human populations. In addition, sustainable forestry in tropical countries must be supported by adequate policies to promote and maintain specific activities at local and regional scales.

  • In the decade that has passed since the first edition of this book, the global environment has changed rapidly. Even the most steadfast ‘‘deny-ers’’ have come to accept that atmospheric CO2 enrichment and global warming pose serious challenges to life on Earth.

  • Whereas the mechanical performance of plant organs has often been discussed in evolutionary biology [1,2], tree biomechanics has rarely been considered in the context of functional ecology. Functional ecology aims at understanding the functions of organisms that result in fluxes of biomass or energy within an ecosystem, e.g., a forest. This discipline studies the processes controlling these fluxes, at either the scale of an individual, community, or ecosystem, with their response to natural or anthropic environmental variations....

  • Ecotoxicological models have been applied increasingly to perform chemical risk assessments since the first models of this kind emerged about 25 years ago. The first ecotoxicological models were applied to very specific cases — for instance, cadmium contamination of Lake Erie or mercury contamination of Mex Bay, Alexandria. The models were inspired by the experience gained in ecological modeling and therefore contained good descriptions of ecological processes. Slightly later, the so-called fate models emerged, which were first developed by McKay and others.

  • An Ecosystem Approach provides a modern perspective of insect ecology that integrates two approaches traditionally used to study insect ecology: evolutionary and ecosystem. This integration substantially broadens the scope of insect ecology and contributes to prediction and resolution of the effects of current environmental changes, as these affect and are affected by insects. The third edition includes an updated and expanded synthesis of feedback and interactions between insects and their environment.

  • Urban Ecology is the study of ecosystems that include humans living in cities and urbanizing landscapes. It is an emerging, interdisciplinary field that aims to understand how human and ecological processes can coexist in human-dominated systems and help societies with their efforts to become more sustainable. It has deep roots in many disciplines including sociology, geography, urban planning, landscape architecture, engineering, economics, anthropology, climatology, public health, and ecology.

  • First and foremost, it is a book geared towards fish aquarists. And it is a heavy read with alot of chemistry and biology. To sum up the book: the author wrote the book to bring it to the reader's attention that an aquarium is a sort of (semi)closed ecosystem, and it needs to be thought of as this in order to be successful in raising the plants and animals inside the aquarium. she then describes the biological principles behind her methods of setting up and maintaining "low-tech" planted aquariums (as opposed to hi-tech, like those of takashi amano). She uses...

  • It is intended that this book be suitable for a variety of engineers and ecologists, who may wish to gain an introduction to the rapidly growing field of ecological and environmental modelling. An understanding of the fundamentals of environmental problems and ecology, as presented for instance in the textbook Principles of Environmental Science and Technology is assumed. Furthermore, it is assumed that the reader has either a fundamental knowledge of differential equations and matrix calculations or has read the Appendix, which gives a brief introduction to these topics....

  • A sequel to the bestselling Ecological Risk Assessment, Ecological Risk Assessment for Contaminated Sites focuses on how to perform ecological risk assessments for Superfund sites and locations contaminated by improper disposal of wastes, or chemical spills. It integrates the authors' extensive experience in assessing ecological risks at U.S. government sites with techniques and examples from assessments performed by others.

I initially thought that the process was going to be very straightforward. The USEPA had produced a framework document and there were published case studies.
