Plant Production in Closed Ecosystems


Book Description

Plant Production in Closed Ecosystems provides overviews of the current trends and concepts in plant production in closed or semi-closed environments. The overviews reflect both the present and future challenges that face the agricultural industry and the methods and tools which will meet these challenges. Plant Production in Closed Ecosystems contains the full texts of the Special Lectures from the International Symposium on Plant Production in Closed Ecosystems, plus several contributed papers. The challenges which await the agricultural industry are diverse. This diversity is reflected in the topics that were covered in the special lectures given by experts in the field. These topics included: greenhouse horticulture, hydroponics, micropropagation, food production in space, environmental control, co-generation, controlled ecological life support systems (CELSS), and resource conservation.




Plant Life under Changing Environment


Book Description

Plant Life under Changing Environment: Responses and Management presents the latest insights, reflecting the significant progress that has been made in understanding plant responses to various changing environmental impacts, as well as strategies for alleviating their adverse effects, including abiotic stresses. Growing from a focus on plants and their ability to respond, adapt, and survive, Plant Life under Changing Environment: Responses and Management addresses options for mitigating those responses to ensure maximum health and growth. Researchers and advanced students in environmental sciences, plant ecophysiology, biochemistry, molecular biology, nano-pollution climate change, and soil pollution will find this an important foundational resource. - Covers both responses and adaptation of plants to altered environmental states - Illustrates the current impact of climate change on plant productivity, along with mitigation strategies - Includes transcriptomic, proteomic, metabolomic and ionomic approaches




Principles of Terrestrial Ecosystem Ecology


Book Description

Features review questions at the end of each chapter; Includes suggestions for recommended reading; Provides a glossary of ecological terms; Has a wide audience as a textbook for advanced undergraduate students, graduate students and as a reference for practicing scientists from a wide array of disciplines




The Economics of Non-Convex Ecosystems


Book Description

Economists often assume that ecosystem and population dynamics are subject to convex, even linear processes. But research by ecosystem and population ecologists suggests that such processes are very often non-convex, for example a possible flip of the Gulf Stream due to fresh water intrusion from melting glaciers. This has dramatic implications for environmental and resource economics, since mistakes in management could prove more costly than imagined.




Tundra Ecosystems


Book Description

Brings together the results of research programmes in Austria, Canada, U.S.A., Finland, Norway, Sweden, Greenland, U.K., Ireland, U.S.S.R. and the Antarctic describing tundra and related ecosystems in a comparative manner. Includes sections on the abiotic, plant production and fauna components, the decomposer cycle and the utilisation and conservation of tundra.

Terrestrial Ecosystem Ecology


Book Description

Human activities impact the environment and modify the cycles of important elements such as carbon and nitrogen from local to global scales. In order to maintain long-term and sustainable use of the world's natural resources it is important that we understand how and why ecosystems respond to such changes. This book explains the structure and functioning of terrestrial ecosystems, using examples ranging from the Arctic to the tropics to demonstrate how they react under differing conditions. This knowledge is developed into a set of principles that can be used as starting points for analysing questions about ecosystem behaviour. Ecosystem dynamics are also considered, illustrating how ecosystems develop and change over a range of temporal and spatial scales and how they react to perturbations, whether natural or man-made. Throughout the book, descriptive studies are merged with simple mathematical models to reinforce the concepts discussed and aid the development of predictive tools.







Forest Ecosystems


Book Description

The common idea for many people is that forests are just a collection of trees. However, they are much more than that. They are a complex, functional system of interacting and often interdependent biological, physical, and chemical components, the biological part of which has evolved to perpetuate itself. This complexity produces combinations of climate, soils, trees and plant species unique to each site, resulting in hundreds of different forest types around the world. Logically, trees are an important component for the research in forest ecosystems, but the wide variety of other life forms and abiotic components in most forests means that other elements, such as wildlife or soil nutrients, should also be the focal point in ecological studies and management plans to be carried out in forest ecosystems. In this book, the readers can find the latest research related to forest ecosystems but with a different twist. The research described here is not just on trees and is focused on the other components, structures and functions that are usually overshadowed by the focus on trees, but are equally important to maintain the diversity, function and services provided by forests. The first section of this book explores the structure and biodiversity of forest ecosystems, whereas the second section reviews the research done on ecosystem structure and functioning. The third and last section explores the issues related to forest management as an ecosystem-level activity, all of them from the perspective of the "other" parts of a forest.
